abstract = {In 2020, I wrote an mSphere of Influence commentary on two studies that shaped my research perspective on the human gut microbiome (McNulty et al., Sci Transl Med 3:106ra106, 2011, https://doi.org/10.1126/scitranslmed.3002701; Hamilton et al., Gut Microbes 4:125, 2013, https://doi.org/10.4161/gmic.23571). The microbiome field has continued to progress since the publication of these studies over 10 years ago, emerging as a considerable factor in almost all areas focused on disease development. My previous commentary highlighted two areas that piqued my interest early on in my career: (i) that the extant microbial community should be considered when proposing to manipulate the microbiota, such as via probiotics or fecal microbiota transplantation, and (ii) that realized (i.e., transcribed) functional changes of the microbiota may occur independent of changes in its composition. Since writing that commentary, two microbiota-based therapeutics for the treatment of Clostridioides difficile infection have been approved, highlighting the potential success of using the microbiota to treat or prevent disease. Despite these wins and ever-growing evidence of the importance of the microbiome in managing our health, translating mechanistic studies into therapeutic value has been slower. In this minireview, I expand upon two large questions that would increase our ability to translate the microbiome into therapies, highlighting both historical and recent progress.},

abstract = {Gut microbiota dysbiosis has been observed in HBV-related cirrhosis, but its role in early-stage disease and its correlation with liver pathology remain unclear. Moreover, whether dysbiosis is a cause or consequence of liver cirrhosis is still debated. We recruited 20 treatment-naïve patients with chronic HBV infection, assessing liver injury via biopsy. Fecal metagenomic sequencing was used to analyze the correlation between gut microbiota and liver histology. To explore the causality, fecal samples from an HBV-related cirrhosis patient were transplanted into mice with CCl4-induced liver fibrosis. Patients with significant histological damage exhibited reduced alpha diversity and greater microbial homogeneity. Species such as Eubacterium_sp_CAG_180, Gemmiger_formicilis, and Oscillibacter_sp_ER4 had decreased abundance, while Parabacteroides_distasonis, Bacteroides_dorei, and Bacteroides_finegoldii were enriched. Mice receiving fecal transplants from the cirrhotic patient showed aggravated liver fibrosis, with increased collagen deposition; elevated ALT, AST, and ALP levels; and heightened hepatic inflammatory gene expression. Additionally, abnormal bile acid profiles with elevated unconjugated bile acids (e.g., GCA and CA) were observed. Gut microbiota dysbiosis is closely associated with liver histological damage in chronic HBV infection and may drive fibrosis progression via microbial-bile acid interactions. These findings suggest potential for gut microbiota-based assessment and treatment strategies in chronic hepatitis B.IMPORTANCEThis study elucidates a significant association between gut microbiota dysbiosis and liver histological damage in patients with chronic hepatitis B (HBV), potentially exacerbating fibrosis progression through bile acid interactions. By analyzing patient gut microbiota and conducting fecal transplant experiments in mice, researchers have identified that gut microbiota dysbiosis contributes to hepatic fibrosis during chronic HBV infection. These findings underscore the importance of the gut-liver axis in HBV disease progression, indicating that monitoring or modulating gut bacteria may facilitate early diagnosis or therapeutic interventions. This research bridges the gap in understanding whether microbial alterations drive disease progression or result from it, providing a foundation for developing therapies targeting the microbiome to mitigate liver damage in chronic HBV infections.},

abstract = {Mild cognitive impairment (MCI) is a transitional stage between normal aging and Alzheimer's disease (AD). Recent studies suggest that alterations in gut microbiota and microbial metabolites are associated with cognitive decline, highlighting the gut-brain axis as a potential therapeutic target. This narrative review explores current evidence on the relationship between gut microbiota, microbial metabolites, and MCI. It summarizes intervention strategies including probiotics, prebiotics, synbiotic, fecal microbiota transplantation, dietary modifications, medicinal herbs, phytochemicals, metformin, and lifestyle factors. Probiotic strains such as Lactobacillus and Bifidobacterium have shown cognitive benefits. Adherence to the Mediterranean and MIND diets, as well as metformin use, is associated with lower MCI risk. Novel strategies, including plant-based compounds and nature exposure, show promise in modulating gut microbiota and improving cognitive outcomes. Gut microbiota modulation represents a promising avenue for early intervention in MCI. Personalized, multifactorial approaches based on individual microbiome profiles may enhance prevention and management strategies. However, more high-quality clinical trials are needed to establish evidence-based guidelines.},

abstract = {Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by amyloid-beta (Aβ) plaques, tau hyperphosphorylation, and chronic neuroinflammation. While neuroinflammation-mediated by microglial and astrocyte activation-has long been considered a secondary response to Aβ pathology, emerging evidence positions it as a primary driver of cognitive decline. Notably, the gut microbiota, through the microbiota-gut-brain axis (MGBA), is crucial in modulating neuroinflammation. Dysbiosis disrupts gut barrier integrity, promotes systemic inflammation, and exacerbates neuroinflammatory responses, thereby accelerating AD progression. Recent advances reveal that gut microbiota-derived metabolites (e.g., short-chain fatty acids, lipopolysaccharides) directly influence microglial activation and Aβ aggregation. These findings have opened new therapeutic possibilities, with microbiota-targeted approaches such as probiotics, prebiotics, and fecal microbiota transplantation demonstrating promising neuroprotective effects in preclinical studies by reducing neuroinflammation and preserving cognitive function. However, translating these findings into clinical applications requires further validation through randomized controlled trials. This review summarizes the current understanding of gut microbiota-driven neuroinflammation in AD, from molecular mechanisms to potential therapeutic strategies. Targeting the MGBA represents a paradigm shift in AD management, emphasizing the modulation of neuroinflammation and pathological progression through gut microbiota interventions. The discussion also addresses existing research challenges and outlines future directions to advance this promising field.},

abstract = {PURPOSE: The pathogenesis of pancreatic cancer (PC) is extremely complex and involves genetic and environmental factors, as well as significant changes in the immune response to tumor cells from the loss of immune surveillance to the development of immunotolerance to cancer. Currently available literature data on this subject is inconsistent. The purpose of our study was to evaluate the status of dendritic cells (DC) and other immune cells in the pancreas and blood of mice genetically predisposed to pancreatic cancer (Kras[G12D] mutation). The second objective was to assess the impact of fecal microbiota transplantation (FMT) from PC mice on pancreatic tumor development and alterations in pancreatic and blood immune cell counts in mice genetically predisposed to PC.

METHODS: We used LSL-K-Ras[G12D] mice, which possess the conditional knock-in mutant K-Ras[G12D] driven by its endogenous promoter and Ela-CreERT mice, which express tamoxifen-regulated CreERT specifically in pancreatic acinar cells under the control of a full-length elastase gene promoter. The immunophenotype of immune cells separated from pancreatic tissue and circulating blood was analyzed with the use of multicolor flow cytometry and immunochemistry staining. Fecal pellets from LSL-K-Ras[G12D] mice, that developed PC after the cerulein (CER) treatment, were collected and transplanted into animals previously treated with the antibiotic.

RESULTS: Using immunohistochemistry and flow cytometry, we found that in mice genetically predisposed to PC, cerulein (CER) administered intraperitoneally induced tumor growth and inflammatory cell infiltration in pancreatic tissue, but without affecting immune cell differentiation in the blood. In contrast, orally administered FMT activated the immune system in the gastrointestinal tract, leading to generalized immune cell activation, as observed in the blood, and local infiltration of cells in the pancreatic tissue of Kras mutant mice that developed pancreatic tumors. Interestingly, immunohistochemical evaluation of pancreatic tissue revealed that the Kras mutation alone causes increased infiltration of CD11b[+], CD20[+], CD3[+], CD4[+], and CD8[+] cells. After FMT, there was a trend toward an increased intensity of infiltration by these immune cells, with the exception of CD11b[+].

CONCLUSIONS: Our data suggest that pancreatic cancer development in genetically predisposed mice is accompanied by profound changes in immune cell composition. Treatment with tumor-inducing agents such as CER or FMT from tumor-bearing mice, accelerated PC progression. The type of immune system response, systemic or local, in mice with pancreatic cancer depends on the route of entry of the inflammatory agent. Oral administration of FMT activated the systemic immune response, in contrast to the intraperitoneal injection of CER.},

abstract = {AIM: To prospectively evaluate the effect of preoperative radiotherapy followed by surgery versus surgery alone on patient-reported outcomes (PROs) 1 year after surgery.

METHOD: Prospective observational cohort study in 127 colorectal cancer centres. Patients with rectal cancer completed European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core (EORTC-QLQ-C30) and Colorectal module (-CR29) questionnaires (thus providing PROs) before initialization of treatment [baseline (T0)] and at 12 months after surgery [follow up (T1)]. The PRO data together with sociodemographic information were linked to clinical data. Relevant confounders were identified using directed acyclic graphs. The effect of preoperative radiotherapy on selected PROs 12 months after surgery was estimated using adjusted tobit regression models.

RESULTS: Of 1635 patients with rectal cancer for whom both baseline and follow-up PROs were available, 565 (35%) received preoperative radiotherapy. Twelve months after surgery, patients with surgery alone reported better scores for global health status/Quality of Life, urinary incontinence, faecal incontinence (patients without stoma), dyspareunia (female patients) and impotence (male patients) than did patients receiving preoperative radiotherapy. The statistically significant effects ranged between 33.20 (p < 0.001, R[2] = 0.19) for impotence and 39.01 (p = 0.001, R[2] = 0.10) for dyspareunia. For global health status/QoL and urinary incontinence, no statistically significant effect could be found.

CONCLUSION: Radiotherapy in addition to surgery negatively affects selected PROs 1 year after surgery in patients with rectal cancer. Compared with surgery alone, patients report profoundly impaired bowel and sexual function after preoperative radiotherapy. However, global health status/QoL was not affected statistically significantly. These results are an important argument for limiting preoperative radiotherapy to patients with a high risk of recurrence of rectal cancer and may facilitate informed decision-making.

abstract = {BACKGROUND: Gut microbiota has emerged as a promising therapeutic target for neurodegenerative disorders through regulation of neuroinflammatory responses, while its role in optic nerve degeneration remains incompletely characterized. This study elucidates the neuroprotective role of gut microbiota derived tryptophan metabolites in glaucoma through gut-eye communication and inhibition of microglia-mediated neuroinflammation.

METHODS: Gut microbiota profiling (16 S rRNA sequencing) and serum indoleacetic acid (IAA) quantification were performed in glaucoma patients versus controls. Microbiota-metabolite relationships were further validated through fecal microbiota transplantation (FMT). The neuroprotective and anti-neuroinflammatory effect of Bacteroides fragilis (B. fragilis) and IAA was assessed in both microbead-induced ocular hypertension mice model and in vitro BV-2 microglial cell inflammation model via immunofluorescence, qPCR, Western blot and mice behavioral assays. To explore the underlying mechanisms, retinal transcriptomics and microglia-neuron co-cultures were also employed.

RESULT: Glaucoma patients exhibited gut dysbiosis characterized by depleted tryptophan-metabolizing bacteria (B. fragilis, Bacteroides thetaiotaomicron, Anaerostipes hadrus) and reduced serum IAA levels. Mice receiving FMT from glaucoma patients exhibited lower systemic IAA levels. In in vivo and in vitro models, B. fragilis or IAA restored AhR activation, suppressed inflammation by inhibiting microglial activation and the release of pro-inflammatory mediators throughout the retina, reduced retinal ganglion cells (RGCs) loss and preserved visual function. Mechanistically, IAA attenuated RAGE/NF-κB pathway activation via AhR-dependent signaling, conferring neuroprotection.

CONCLUSION: Our study proposes a novel AhR-mediated gut microbiota-eye axis in glaucoma pathogenesis and demonstrates that IAA serves as an effective neuroprotective strategy with clinical potential for managing RGCs neurodegeneration.},

Fecal microbiota, live-jslm (REBYOTA; RBL, previously RBX2660) was shown to prevent recurrent C difficile infection in a phase 3 clinical trial (PUNCH CD3) based on a randomized, double-blinded, placebo-controlled design.

METHODS: Stool samples from participants in PUNCH CD3 who received a single blinded dose of rectally administered RBL or placebo were sequenced to determine microbial community composition and calculate the Microbiome Health Index for postantibiotic dysbiosis. The composition of bile acids (BAs) in the same samples was quantified by liquid chromatography-mass spectrometry. Relationships between BA composition and microbiota community structure and correlations with treatment outcomes were assessed.

RESULTS: Before administration, Gammaproteobacteria and Bacilli dominated the microbiota community, and primary BAs were more prevalent than secondary BAs. Clinical success after administration correlated with shifts to predominantly Bacteroidia and Clostridia, a significant increase in Microbiome Health Index for postantibiotic dysbiosis, and a shift from primary to secondary BAs. Several microbiota and BA changes were more extensive in RBL-treated responders as compared with placebo-treated responders, and microbiota changes correlated with BA changes.

CONCLUSIONS: Clinical response and RBL administration were associated with significant restoration of microbiota and BA composition.

In this study, we performed a multi-center, double-blind randomized placebo-controlled trial to investigate the efficacy and safety of herbal medicine JCM-16021 on IBS-D with a focus on its effects on gut microbiota.

RESULTS: Our study assessed the clinical efficacy and safety of JCM-16021 in alleviating abdominal pain in IBS-D patients. The results suggested that JCM-16021 is both effective and safe, with its therapeutic effects closely linked to the modulation of short-chain fatty acid (SCFA) producers. Through fecal microbiota transplantation (FMT) experiments in mice, we showed that SCFA producers mediate the alleviation of abdominal pain symptoms by the JCM-16021 treatment. In a TNBS-induced mouse model of IBS, we showed that butyrate producers enriched by JCM-16021 significantly ameliorate abdominal pain. Importantly, baseline gut microbial profiles, such as the presence of Eubacterium rectale in IBS-D patients are predictive of their responses to JCM-16021 treatment.

CONCLUSIONS: Our findings not only affirm the efficacy of JCM-16021 in mitigating abdominal pain in IBS-D patients but also highlight a microbiota-dependent mechanism, underscoring the therapeutic potential of gut microbiota modulation in treating gastrointestinal disorders. By combining clinical trials in humans with biological experiments in mice, this study establishes a translational approach to investigate the role of gut microbiota in the treatment of herbal medicine.

abstract = {Atherosclerosis is a common chronic inflammatory cardiovascular disease affecting both coronary and peripheral arteries, which is influenced by multiple factors. It is increasingly evident that gut microbes and their byproducts play a crucial role in the development of atherosclerosis. The most representative feature of microbial dysbiosis in coronary artery disease patients is the reduction of the abundance of the phylum Bacteroidetes and the increase of the abundance of the phylum Firmicutes, which may cause changes in functional genes and metabolites. The gut microbiota and its metabolites influence the early, intermediate, and late stages of atherosclerosis mainly by inhibiting or promoting inflammatory responses. In addition, the reshaping of gut microbiota through probiotics, prebiotics, and fecal microbiota transplantation (FMT) is discussed as an alternative to traditional therapeutic methods. By summarizing how gut microbiota and their metabolites affect the process of atherosclerosis, we can better understand the complex relationship between gut microbiota and atherosclerosis.IMPORTANCEAtherosclerosis is an inflammatory cardiovascular disease, making it crucial to understand its pathogenesis and develop effective treatments.

abstract = {BACKGROUND: The epidemic of overweight and obesity affects more than 390 million children and adolescents aged 5 to 19 years and 37 million children under five years of age. Overweight and obesity are associated with both short- and long-term consequences, including chronic inflammation, metabolic diseases, as well as alterations in the gut microbiome composition. Gut microbiome-based approaches may impact microbiome-related metrics such as diversity or the abundance of intestinal bacteria, which may be linked to obesity-related outcomes. However, evidence regarding the effect of gut microbiome-based interventions for the management of obesity is limited.

OBJECTIVES: To assess the effects of gut microbiome-based interventions in the management of overweight or obesity in children and adolescents in all their diversity aged 0 to 19 years.

SEARCH METHODS: We searched CENTRAL, MEDLINE, CINAHL, Web of Science Core Collection, BIOSIS Previews, Global Index Medicus (all regions), IBECS, SciELO, PAHO, PAHO IRIS, WHO IRIS, WHOLIS, Bibliomap, TRoPHI as well as ICTRP Search Portal and ClinicalTrials.gov. The date of the last search for all databases was 24 January 2025. We did not apply any language restrictions.

SELECTION CRITERIA: We included randomised controlled trials that evaluated gut microbiome-based interventions [i.e. prebiotics, probiotics, synbiotics, short-chain fatty acids (SCFAs), and faecal microbiota transplantation (FMT)] compared to standard-of-care, placebo, or control interventions in children and adolescents aged 0 to 19 years with overweight or obesity.

DATA COLLECTION AND ANALYSIS: Two review authors independently screened titles and abstracts and full texts, extracted data, and assessed the risk of bias using the Cochrane Risk of Bias 2 tool and certainty of the evidence using Grading of Recommendations Assessment, Development and Evaluation (GRADE), a framework for assessing the certainty of evidence and making recommendations in systematic reviews. Random-effects meta-analyses were performed unless only one study per outcome was available, for which fixed-effect analyses were performed.

MAIN RESULTS: We found 17 studies (838 participants) from various countries, evaluating the effects of prebiotics, probiotics, synbiotics, SCFAs, and FMT on body mass index (BMI), body weight, waist circumference, total body fat percentage (%TBF), systolic and diastolic blood pressure, and adverse events. Of the 17 studies included, five studies were in adolescents aged 10 to 19 years, and 12 studies were in children and adolescents spanning both age groups, 0 to 19 years. Upon contacting authors for data grouped by age of the participants, no studies provided separate outcomes data for children and adolescents. The included studies were funded by either academic funding sources or grants from the public and private sectors. Additionally, 15 studies were classified as currently being conducted ('ongoing'). The certainty of evidence throughout was very low. In adolescents 10 to 19 years of age, probiotics compared to placebo or no intervention may have little to no effect on BMI, body weight, waist circumference, %TBF, blood pressure, and adverse events. Similarly, FMT compared to placebo may have little to no effect on waist circumference, %TBF, blood pressure, and adverse events in this age group. According to one study with 41 participants and in children and adolescents 0 to 19 years of age, intervention with prebiotics compared to placebo may result in a small reduction in BMI (mean difference = -0.70, 95% CI = -1.25 to -0.15) and body weight (mean difference = -1.5, 95% CI = -2.61 to -0.39). Prebiotics compared to placebo may have little to no effect on waist circumference, %TBF, systolic blood pressure, and adverse events. No data were available on the effect of prebiotics on diastolic blood pressure. Probiotics compared to placebo may have little to no effect on BMI, body weight, waist circumference, %TBF, blood pressure, and adverse events in children and adolescents (0 to 19 years). Synbiotics compared to placebo may result in a reduction in systolic blood pressure (mean difference = -40.00, 95% CI = -50.63 to -29.37) in children and adolescents (0 to 19 years); according to one study with 56 participants. The evidence is very uncertain about the effects of synbiotics compared to a placebo on BMI, body weight, waist circumference, blood pressure, and adverse events. No data were available on the effect of synbiotics compared to placebo on %TBF. Synbiotics, compared to probiotics, may have little to no effect on waist circumference, %TBF, and adverse events. No data were available on the effect of synbiotics compared to probiotics on BMI, body weight, and blood pressure. According to one study with 48 participants and very low-certainty of evidence, SCFAs compared to placebo may result in a reduction in waist circumference (mean difference = -5.08, 95% CI = -7.40 to -2.76) and BMI (mean difference = -2.26, 95% CI = -3.24 to -1.28) in children and adolescents (0-19 years). SCFAs compared to placebo may have little to no effect on adverse events. No data were available on the effect of SCFAs on body weight, %TBF, and blood pressure. Adverse events, i.e. abdominal cramps, abdominal discomfort, abdominal pain, diarrhoea, vomiting, and migraine, were reported in the prebiotics group but with very low incidence. Additionally, adverse events such as nausea and headache were reported in the SCFAs group, but with low incidence.

AUTHORS' CONCLUSIONS: In adolescents aged 10 to 19 years, gut microbiome-based interventions may result in little to no difference in obesity-related outcomes. In children and adolescents aged 0 to 19 years, prebiotics may result in a small reduction in BMI and body weight; synbiotics may result in a reduction in systolic blood pressure, and SCFAs may result in a reduction in BMI and waist circumference, albeit the certainty of evidence was very low. The evidence was of very low certainty due to few studies per comparison, small sample sizes, short intervention durations, and insufficient reporting of adverse events. More rigorous research examining different types of gut microbiome-based interventions for the management of obesity is required in children and adolescents, both in clinical and community settings. Future trials should also report methods related to randomisation, blinding, and compliance, as well as include prespecified analysis plans.},

abstract = {Post-traumatic stress disorder (PTSD) is a severe mental disorder that occurs after experiencing or witnessing a traumatic event. Not only does this disorder severely impair the quality of life and emotional wellbeing of patients, but in recent years the global rate of PTSD diagnoses has increased to 1.5-2 times, and the prevalence of PTSD associated with COVID-19 events in particular has surged to 10%-25%, underscoring the urgency of developing effective treatments. The lifetime prevalence of PTSD in the general population is estimated to be approximately 3.9%, while in high-risk populations, such as war veterans, it can be as high as 30%. As a key pathway connecting the central nervous system to peripheral organs, the gut-brain axis has received increasing attention for its role in PTSD. Although the gut-brain axis has been shown to be associated with several psychiatric disorders, especially depression, its specific role in PTSD remains undercharacterized. Existing studies suggest that specific strains of Lactobacillus (e.g., Lactobacillus reuteri) may alleviate inflammatory responses and improve PTSD-like behaviors by down-regulating the expression of pro-inflammatory factors (IL-6 and TNF-α). In this study, we used a narrative review approach to sort out the research progress of gut microbiota alteration in PTSD, and compared the characteristics of changes in specific microbial taxa (e.g., Bacteroides, Lactobacillus, etc.), the index of microbiota diversity (α/β diversity), and the levels of inflammatory markers (e.g., IL-6, TNF-α) between the animal model and the human patients, respectively, in order to We further explored the potential pathogenic mechanisms mediated by microorganisms, such as influencing the vagal pathway, hypothalamic-pituitary-adrenal (HPA) axis function, immune system and other processes involved in the pathology of PTSD, and summarized the intervention strategies targeting gut microecology, such as probiotic supplementation, dietary interventions and fecal bacteria transplantation.},

With the advent of enzyme replacement therapy (ERT), patient survival has improved, revealing new long-term complications. We report a case of a 4-year-old male with severe neurovisceral GD who developed protein-losing enteropathy (PLE) secondary to mesenteric lymphadenopathy, despite ERT starting in the neonatal period. Furthermore, we review the literature related to this rare complication. The patient presented with severe recurrent diarrhea, abdominal distension, weight loss, and malnutrition. Abdominal CT revealed multiple enlarged mesenteric lymph nodes with calcification. Laboratory findings showed lymphopenia and increased fecal alpha-1-antitrypsin. Other causes of diarrhea were excluded. Treatment with a specific diet (high-protein, MCT-enriched) and a course of budesonide resulted in persistent clinical improvement and normalization of laboratory parameters. This case highlights the emergence of gastrointestinal complications in patients with neurovisceral GD on long-term ERT, particularly the development of PLE due to mesenteric lymphadenopathy. It underscores the need for vigilance in monitoring GD patients for such complications and demonstrates the potential efficacy of dietary interventions and anti-inflammatory therapy in managing PLE in this context. The case also emphasizes the limitations of current ERT in addressing all aspects of GD, particularly in sequestered sites like lymph nodes, and calls for new therapeutic strategies to address these challenges.},

FMT was safe and well tolerated, causing only mild, transient gastrointestinal symptoms. While no significant motor symptom changes were observed, there was a trend toward reduced daily OFF time at 2 months. Whilst no sustained improvement in non-motor symptoms was found after 6 months, transient improvements in quality of life and non-motor scores were noted at 2 months; these gains regressed by study end. Overall, extended FMT therapy in PD appears safe and tolerable, with reduction in daily motor OFF time and self-reported non-motor symptoms that was not sustained throughout the 6-months of treatment.},

We conducted whole-genome shotgun sequencing on stool samples (N = 117) collected at various times from patients with multiple myeloma (n = 33) who underwent idecabtagene vicleucel (ide-cel) anti-B-cell maturation antigen CAR-T therapy. We observed a significant decrease in bacterial diversity after ide-cel infusion, along with significant differences in the bacterial composition linked to therapy response and toxicities. Specifically, we found significant enrichment of Flavonifractor plautii, Bacteroides thetaiotaomicron, Blautia fecis, and Dysosmobacter species in ide-cel responders. A notable finding was the link of major microbiome disruption, defined as the presence of dominant specific taxa (>35% prevalence), and increased facultative pathobionts, like Enterococcus, with ide-cel toxicities, especially cytokine release syndrome (CRS). Patients with genus dominance in baseline samples had a higher incidence of grade 2 or higher CRS at 46.2% than those without genus dominance (11.1%; P = .043). In addition, network analysis and mass spectrometric assessment of stool metabolites revealed important associations and pathways, such as F plautii being linked to increased indole metabolites and pathways in responders. Our findings uncovered novel microbiome associations between ide-cel responses and toxicities that may be useful for developing modalities to improve CAR-T outcomes.},

This review aims to provide a comprehensive understanding of dysbiosis and its role in DGBI while examining the latest advancements in fecal microbiota transplantation (FMT). It also highlights key challenges in the field and outlines critical directions for future research to optimize FMT strategies, ultimately improving patient outcomes in this evolving treatment area.

RECENT FINDINGS: In DGBI, dysbiosis triggers immune responses, increases gut permeability, and disrupts nervous system signaling, with contributing factors including diet, antibiotics, stress, and infections. Individuals with DGBI exhibit distinct microbial imbalances, such as an increased Firmicutes-to-Bacteroidetes ratio and reduced beneficial bacteria. FMT has shown mixed results, with factors like patient selection, treatment protocols, and microbiome diversity influencing outcomes. While FMT can improve symptoms in refractory irritable bowel syndrome (IBS), effects may fade over time, requiring repeat treatments. Future FMT approaches should focus on targeted microbial interventions, considering the role of archaea, fungi, and microbial metabolites, while prioritizing optimal donor selection and large-scale trials for long-term efficacy. Despite the promising findings, FMT has not yet been widely endorsed in clinical guidelines due to the variability and heterogeneity of the data available. While much of the research has focused on IBS, studies have also explored the impact of FMT on other conditions such as functional diarrhea, functional constipation, and functional dyspepsia, which all exhibit altered microbial profiles.},

abstract = {UNLABELLED: Gut and oral microbiomes play an essential role in the occurrence and development of kidney disease, but their changes after kidney transplantation in patients with end-stage renal disease and their relationships with host health remain unclear. Through shotgun metagenomic sequencing of fecal and saliva samples, we found that for both gut and oral microbiome, the initial loss of species diversity after kidney transplantation led to a reduction in network nodes and interactions, but strengthened the connections among the remaining species, which started to get a recovery approximately 7-14 days later. Different network modules tended to exhibit unique functions and showed different responses to transplantation. These network changes were significantly correlated with clinical indicators, especially with estimated glomerular filtration rate, suggesting that microbial networks contributed to regulating kidney function and host health from dual dimensions. Our study provides novel insights into associating microbiomes with patient recovery after kidney transplantation and offers new diagnostic strategies.

IMPORTANCE: Understanding the dynamics of gut and oral microbiomes after kidney transplantation is crucial for improving post-transplant outcomes and managing potential complications. Through shotgun metagenomic sequencing of fecal and saliva samples from patients following kidney transplantation, our study emphasizes that, in addition to focusing on the various microbial species themselves, the topological properties of gut and oral microbial networks are also critically important for kidney function. We aim to explore the relationship between host health and the oral and gut microbiomes following kidney transplantation from an ecological perspective and extend to other diseases to advance the study of the microbiome and its clinical impact.},

In this study, we aimed to determine the association between gut microbiome diversity, diet, SUA, and fractional excretion of uric acid (FEUA) in the kidney.

METHODS: A cross-sectional study was conducted in 53 adults with normal or elevated SUA and estimated glomerular filtration rate (eGFR) range from 37 to 124 ml/min per 1.73 m[2]. Fecal microbiome composition was analyzed using 16S ribosomal RNA sequencing; and alpha diversity was expressed as reverse Simpson, Shannon, and Richness indices. Dietary data were collected, and dietary patterns were identified using principal component analysis. Unadjusted linear regression and models adjusted for sex, waist-hip ratio (WHR), and eGFR were used to study the association between gut microbial diversity, dietary pattern scores, and SUA/FEUA.

RESULTS: Shannon index was negatively associated with SUA after multiple adjustment (β -36.4, 95% CI [-66.2 to -6.7], P = 0.017; adjusted R[2] = 0.62, P < 0.001). Sex (standardized β = 0.52) and WHR (standardized β = 0.35) had the highest effect on SUA, followed by Shannon diversity index (standardized β = -0.22). We found that Shannon index (standardized β = 0.49, P < 0.001) was positively associated with FEUA after adjustment for sex and "sweet" dietary pattern. This model explained 40% of the variability in FEUA (P < 0.001). None of the dietary patterns were associated with SUA or FEUA.

CONCLUSION: A higher gut microbial diversity was associated with lower SUA and more efficient elimination of uric acid by the kidneys. There is a need for studies assessing efficacy and safety of interventions on the gut microbiome as a treatment of hyperuricemia.},

This article uniquely integrates a systematic review with bibliometric analysis to map the research landscape of AD and microbiota interactions, offering a comprehensive synthesis of trends and future directions.

METHODS: We conducted a bibliometric analysis using the Web of Science Core Collection, retrieving 1,196 English-language articles and reviews published between 2009 and 2024, employing a detailed search strategy targeting AD and microbiota-related terms. Data were analyzed with tools like CiteSpace, VOSviewer, and Biblioshiny to assess publication trends, geographical contributions, institutional outputs, journal impacts, author networks, reference citations, and keyword evolution.

RESULTS: Research on AD and microbiota has surged since 2016, peaking at 168 publications in 2021, with the USA leading in output (360 papers) and citations (24,655). The University of Copenhagen and the Journal of Allergy and Clinical Immunology emerged as top contributors, while authors like Gallo, Richard L., and Kong, Heidi H. drove influential studies. Key findings underscore the skin and gut microbiomes as research hotspots, with Staphylococcus aureus and the gut-skin axis dominating discussions. Emerging trends from 2020 to 2024 focus on adult AD severity, prebiotics, and personalized interventions like fecal microbiota transplantation (FMT), supported by multi omics data.

CONCLUSION: This study illuminates the dynamic growth and global collaboration in AD and microbiota research, emphasizing microbial dysbiosis and immune modulation as pivotal to AD management. These insights pave the way for precision medicine and dietary interventions, promising enhanced therapeutic strategies and improved patient outcomes through continued multidisciplinary efforts.},

While the gut microbiota has gained attention as a potential contributor, few studies have assessed its role in TAC metabolism variability. This study investigated the associations between the gut microbiota and TAC metabolism rates in kidney transplant recipients during the first month post transplantation-a crucial period for adjusting TAC to achieve therapeutic levels. We recruited 20 kidney transplant recipients and profiled their gut microbiota diversity and composition from stool samples collected before transplantation and at weeks 1 and 4 post transplantation via 16S rRNA sequencing. The TAC pharmacokinetic parameters were also collected. Associations between TAC metabolism status or pharmacokinetic parameters and gut microbiota diversity and composition were evaluated. Recipients with a fast TAC metabolism rate (C0/D ratio < 1.05 ng/mL × 1/mg) presented significantly greater changes in both bacterial alpha and beta diversity metrics at 1 week post transplantation than did those with a slow metabolism rate (C0/D ratio ≥ 1.05 ng/mL × 1/mg). Compared with slow metabolizers, fast metabolizers were associated with a significant increase in the abundance of three bacterial genera (Faecalibacterium, Clostridia vadinBB60, and Ruminococcus) and a significant decrease in the abundance of two bacterial species (Bacteroides plebeius and Parabacteroides goldsteinii). This study revealed links between gut microbiota diversity and composition and TAC metabolism rates in kidney transplant recipients during the early posttransplant period, underscoring the importance of investigating the gut microbiota as a contributor to TAC pharmacokinetic variability. Clarifying this causal relationship could better predict inter- and intraindividual TAC pharmacokinetic variability.},

abstract = {INTRODUCTION: Gestational diabetes mellitus (GDM) affects up to 27.6% of pregnancies in certain regions and is associated with a two- to threefold increased risk of neonatal infections. Although maternal gut microbiota undergoes significant remodeling during pregnancy, the specific mechanisms governing GDM-induced microbial reprogramming in offspring and its implications for susceptibility to infections remain unclear. This study aimed to investigate the impact of GDM on the composition of neonatal gut microbiota, metabolomic profiles, and susceptibility to infections using a translational approach.

METHOD: We recruited pregnant women with and without GDM at the JinHua Municipal Central Hospital in China. Meconium and blood samples were collected from newborns within 24 h of birth. The composition of the gut microbiota was analyzed using 16S rDNA amplicon sequencing, and short-chain fatty acids (SCFAs) were quantified using gas chromatography-mass spectrometry. Serum inflammatory markers, including interleukin-6 (IL-6), C-reactive protein (CRP), lipopolysaccharides (LPS), and procalcitonin (PCT), were measured by enzyme-linked immunosorbent assay. To establish causality, fecal microbiota transplantation (FMT) was conducted in antibiotic-treated mice using pooled samples from healthy and GDM-exposed neonates, followed by assessment of inflammatory markers and intestinal barrier integrity.

RESULTS AND DISCUSSION: GDM significantly reduced the diversity of neonatal gut microbiota and altered its composition, characterized by a depletion of beneficial taxa (Bifidobacterium, Blautia, Faecalibacterium) and an enrichment of potential pathogens (Stenotrophomonas, Chryseobacterium). These alterations were accompanied by significant reductions in fecal SCFAs, particularly acetate (49.30%), butyrate (41.00%), and propionate (17.83%). GDM-exposed neonates exhibited elevated serum inflammatory markers, including IL-6, CRP, LPS, and PCT, which correlated negatively with beneficial bacteria and positively with opportunistic pathogens. FMT experiments demonstrated that mice receiving GDM-associated microbiota developed increased systemic inflammation and compromised intestinal barrier function, as evidenced by the downregulation of tight junction proteins (ZO-1, occludin, claudin-1, mucin1). These findings suggest that GDM-induced alterations in neonatal gut microbiota composition and metabolite production may compromise intestinal barrier function and increase susceptibility to infections, highlighting the potential for microbiome-targeted interventions to mitigate infection risk in GDM-exposed neonates.},

At the same time, the expression of BAS synthase and the effects of FXR-SHP and FXR-FGF15-FGFR4 signaling pathways on BAS homeostasis were also explored. The fecal microbiota of obese mice intervened by GOS could reshape the structure of intestinal microbiota, regulate the synthesis of bile acids in the enterohepatic circulation and the expression of transport-related factors, and promote metabolic ability to exert anti-obesity effects.},

It can gradually progress to more severe diseases, including steatohepatitis, cirrhosis and hepatocellular carcinoma. Studies have highlighted the importance of the gut microbiome in the pathogenesis and progression of MASLD. On the other hand, increasing evidence has revealed the clinical potential of targeting the gut microbiome to treat MASLD. In this Review, we summarize gut microbial alterations in MASLD, metabolic dysfunction-associated steatohepatitis and hepatocellular carcinoma. The mechanisms by which a dysregulated gut-liver axis contributes to disease progression are also described, including intestinal barrier dysfunction, chronic inflammation, and altered metabolic pathways (for example, bile acids) and microbial-derived metabolites (for example, short-chain fatty acids, tryptophan derivatives and endogenous ethanol). In addition, we discuss the clinical implications of utilizing the gut microbiome as a diagnostic biomarker and the therapeutic approaches to treat MASLD and related diseases such as faecal microbiota transplantation, probiotics and engineered bacteria, prebiotics and postbiotics, microbial-derived metabolites, antimicrobials and bacteriophages. Finally, we discuss current challenges in basic and translational research on the microbiome in MASLD and propose future directions to drive progress in this field.},

abstract = {Oral bile acids, particularly hyodeoxycholic acid (HDCA), serve as critical drivers for gut microbial community maturation in mice. In the first study, Cy5-labeled HDCA combined with fluorescence imaging revealed rapid gastrointestinal transit of HDCA in piglets, contrasting with its delayed absorption observed in mice. In the second study, the effects of the oral HDCA supplementation on microbiota-host metabolic interactions were investigated using four piglet model groups: OPM-HDCA (naturally born, raised germ-free (GF), and orally administered HDCA), OPM-CON (naturally born, raised GF, and orally administered PBS), SPF-HDCA (naturally born, raised GF, and received fecal microbiota transplantation (FMT) and HDCA), and SPF-CON (naturally born, raised GF with FMT but no HDCA). The results demonstrated that HDCA administration at 0.2 mg/mL suppressed body weight gain in piglets, which was alleviated by FMT. HDCA significantly altered gut microbiota composition in SPF piglets, markedly increasing the Lactobacillus abundance (37.97% vs. 5.28% in SPF-CON) while decreasing the proportion of Streptococcus (28.34% vs. 38.65%) and pathogenic family Erysipelotrichaceae (0.35% vs. 17.15%). Concurrently, HDCA enhanced intestinal barrier integrity by upregulating tight junction proteins (ZO-1, Claudin, Occludin) and suppressing pro-inflammatory cytokines (TNF-α, IL-1β). Additionally, HDCA significantly upregulated ileal gene expression of CYP7A1 (cytochrome P450 family 7 subfamily A member 1) and TGR5 (G protein-coupled bile acid receptor 1) in both SPF-HDCA and OPM-HDCA groups compared to their respective controls (p < 0.05). These findings demonstrate that HDCA exerts microbiota-dependent effects on growth performance, intestinal barrier function, and bile acid metabolism in piglets. Although 0.2 mg/mL HDCA treatment suppressed body weight gain, it potentially enhanced intestinal barrier integrity by activating the TGR5 signaling pathway and increasing the abundance of beneficial bacteria such as Lactobacillus. These results also highlight the critical role of early-life gut microbiota in nutritional interventions, providing a basis for developing precision nutritional strategies targeting intestinal microbial ecology in piglets.},

The pathogenesis of IgAN is the multi-hit hypothesis regarding overproduction and accumulation of galactose-deficient (Gd-IgA1). Recent findings have revealed gut microbiota dysbiosis and immune responses are essential in the development of IgAN, attracting increasing attention. This study aimed to map mucosal immune cells in IgAN influenced by gut microbiota, investigating the role of innate immune cells in kidney damage.

METHODS: Fecal samples were acquired from both patients and controls for subsequent animal experiments. Mice received a broad-spectrum antibiotic cocktail to eliminate their intestinal microflora, followed by a gavage with fecal microbiota from clinical individuals. Murine intestinal and kidney tissues were collected for flow cytometry. Intestine and kidney histopathology, immunofluorescence, and inflammatory cytokine expression were assessed in the murine models. The mucosal epithelium's structure and function, along with the innate immune cell response, were analyzed.

RESULTS: Mice exhibited the IgAN phenotype following colonization with gut microbiota from IgAN patients. These mice (IgAN-FMT mice) showed renal dysfunction and increased pathology of tissue injury in both intestine and kidneys. IgAN-FMT mice showed heightened pro-inflammatory cytokine (IL-6 and TNF-α) activity, greater antibody (IgA and complement C3) deposition and decreased expression of mucosal barrier protein (ZO-1, Occludin) compared to the control group. Furthermore, CD11c[+]dendritic cells were more abundant in the murine intestine and kidneys compared to the control group.

CONCLUSION: The gut-kidney axis, including microbiota homeostasis and innate immune cell response, contributes to the pathogenesis of IgAN. Gut dysbiosis and hyperactivated immune cells like CD11c[+]dendritic cells can affect the mucosal barrier and exacerbate the renal damage, being novel insights into immunotherapeutic strategies for IgAN.},

abstract = {The relationship between gut microbiota and intestinal motility is crucial for maintaining gastrointestinal health. Intestinal motility refers to the coordinated movements of the digestive tract, essential for effective digestion, nutrient absorption, and timely waste elimination. Recent studies have demonstrated that microbiota play a crucial role not only in the maturation of intestinal motility but also in the ongoing maintenance of established motility patterns. Disruptions in motility can lead to various disorders, such as chronic constipation, irritable bowel syndrome, and chronic idiopathic pseudo-obstruction. Gut microbiota significantly influence intestinal motility through mechanisms like bile acid metabolism and the production of short-chain fatty acids. In patients with diarrhea-predominant irritable bowel syndrome, elevated primary-to-secondary bile acid ratios suggest a complex interaction between gut bacteria and bile acids that can enhance motility via receptors like TGR5. Additionally, the role of interstitial cells of Cajal in facilitating non-neuronal contractions has revolutionized our understanding of motility regulation, highlighting both neural and non-neural factors. Various therapeutic approaches, including prebiotics, probiotics, and fecal microbiota transplantation, have been explored to improve intestinal motility, although their effectiveness has been limited. Advancements in gene-related research and innovative diagnostic methods are vital for a deeper understanding of how the gut microbiome regulates motility. This review synthesizes current knowledge on the interplay between gut microbiota and intestinal motility, emphasizing the need for interdisciplinary research to develop effective treatments targeting gut microbiota for gastrointestinal disorders. By unraveling these complex interactions, we can pave the way for novel therapeutic strategies that enhance intestinal health and improve the quality of life for those affected by motility-related disorders.},

abstract = {BACKGROUND: Insomnia has been a public problem threatening human health. Wendan Decoction (WDD) has good therapeutic effects on insomnia. However, its mechanism to improve sleep remains unclear.

PURPOSE: To investigate the potential mechanism of WDD in treating insomnia from the perspective of gut microbiota and metabolism.

METHODS: The chemical composition of WDD was analyzed by UHPLCOrbitrap Exploris/MS. The efficacy of WDD on PCPA-induced insomnia rats was evaluated through behavioral tests, ELISA, histopathological examination, immunofluorescence and western blotting. 16S rRNA sequencing, untargeted metabolomics, and network pharmacology were integrated to explore the mechanism of WDD in treating insomnia. The role of gut microbiota in WDD treatment was validated by antibiotic treatment and fecal microbiota transplantation (FMT). Targeted metabolomics was used to detect changes in fecal tryptophan metabolites after FMT. Additionally, RT-qPCR and western blotting were used to investigate the potential mechanisms.

RESULTS: WDD effectively shortened sleep latency, prolonged sleep duration, alleviated anxiety-like behaviors, attenuated neuronal damage, and modulated neurotransmitter levels in rats with insomnia. Moreover, WDD alleviated intestinal damage, reduced the number of Iba-1 positive cells, increased IL-10 levels and decreased IL-6, IL-1β, TNF-α and LPS levels in the colon, serum and hippocampus. It also increased the expression of Occludin, Claudin-1, and ZO-1 in both the colon and brain. 16S rRNA sequencing suggested that WDD improved gut microbiota disorders. Untargeted metabolomics and network pharmacology jointly suggested that WDD could regulate tryptophan metabolism. Antibiotic treatment and FMT confirmed the involvement of gut microbiota in the therapeutic effects of WDD in alleviating insomnia. Changes of tryptophan metabolites in feces, serum, and hippocampus confirmed the regulatory effect of WDD on tryptophan metabolism. Further mechanistic analysis suggested that WDD may correct the abnormal kynurenine pathway of tryptophan metabolism through inhibition of the expression of indoleamine 2,3-dioxygenase 1 and kynurenine-3-monooxygenase.

CONCLUSION: WDD can modulate the neurotransmitter disorders, reduce inflammatory cytokine levels, and strengthen the intestinal barrier and blood-brain barrier by regulating gut microbiota and tryptophan metabolism, thereby improving sleep. This study provides evidence for the potential therapeutic effect of WDD on insomnia via the microbiota-gut-brain axis.},

abstract = {The microbiota plays a crucial role in pediatric health by shaping immune development and influencing infection susceptibility. In infants and children, an immature microbiota may compromise immune defense, increasing the risk of bacterial infections. This review evaluates clinical trials on the microbiota's role in neonatal and pediatric bacterial infections, including sepsis, infections in pediatric cancer patients, and Clostridioides difficile-associated dysbiosis. We summarized original research articles published from 2000 to May 2024 on the microbiota and bacterial infections in neonates and children. A balanced microbiota is essential for infection prevention, particularly in premature infants and immunocompromised children. Studies of microbiome signatures in the gut, oral cavity, and nasopharynx have highlighted how microbiota composition influences infection risk, treatment response, and adverse effects from antibiotics and chemotherapy. Disruptions from antibiotic exposure, chemotherapy, and hematopoietic stem cell transplantation frequently lead to dysbiosis, characterized by depletion of commensal bacteria and overgrowth of pathobionts, including antibiotic-resistant strains such as C. difficile. Conversely, microbiota-restorative interventions, such as probiotics and fecal microbiota transplantation, show promise in reducing bacterial infections by enhancing microbial resilience. The microbiota plays a critical role in predicting and potentially treating bacterial infections in children. While antibiotics remain essential, their widespread use has significant consequences for microbiota health. Striking a balance between effective infection control and microbiota preservation is crucial, particularly in vulnerable pediatric populations. Implementing judicious antibiotic use and exploring microbiota-based therapies may mitigate long-term microbiota disruptions, ultimately improving infection outcomes and overall pediatric health.},

This study elucidates the bidirectional relationship between gut microbiota and AD using fecal microbiota transplantation (FMT) in a mouse model.

RESULT: Through meticulous experimentation, we conducted reciprocal FMT between AD (5xFAD) and healthy (C57BL/6) mice to unravel the impact of gut microbiome alterations on cognitive function and neuroinflammation. FMT from 5xFAD to C57BL/6 mice induced profound memory impairment and cognitive deficits, accompanied by elevated inflammatory cytokine levels, oxidative stress markers, and systemic inflammation, as evidenced by increased plasma cytokines. Conversely, transplanting healthy microbiota into 5xFAD mice yielded remarkable behavioral improvements, including enhanced spatial memory performance in the Morris water maze, directly correlating with cognitive recovery. Our findings underscore the pivotal role of the gut microbiome in AD pathogenesis and offer a promising therapeutic avenue.

CONCLUSION: Targeted modulation of the gut microbiome through strategies like FMT may offer potential benefits in Alzheimer's disease by influencing neuroinflammation, oxidative stress, and cognitive function. This comprehensive study provides novel insights into the gut-brain axis dynamics and paves the way for innovative microbiome-based interventions in AD management.},

abstract = {The risk of cognitive impairment is markedly elevated in patients with type 2 diabetes mellitus (T2DM). While exercise has been shown to mitigate cognitive deficits associated with diabetes, the underlying mechanisms remain poorly understood. Recent studies suggest that exercise can modulate the composition of the gut microbiota, which, in turn, may influence the central nervous system via the microbiota-gut-brain axis. However, the specific role of gut microbiota in mediating exercise-induced improvements in cognitive function in T2DM remains unclear. In this study, we aimed to investigate whether exercise can alleviate cognitive impairment in T2DM mice by modulating the intestinal microbiota, and to elucidate the mechanisms underlying this effect. This study was conducted using male C57BL/6J mice. Mice fed a normal diet were assigned to the non-diabetic control group (NC), while those fed a high-fat diet were intraperitoneally injected with streptozotocin (STZ) and subsequently divided into the diabetic control group (DM), an exercise group (DM-EXE), and a fecal microbiota transplantation group (DM-FMT). The DM-EXE group underwent treadmill exercise for 8 weeks. During this period, the DM-FMT group received fecal microbiota transplants from the DM-EXE group for 2 consecutive days per week. Following the 8-week intervention, stool samples were collected for 16S rDNA high-throughput sequencing. The fear conditioning test was performed to assess cognitive function. Intestinal mucosa samples were collected to evaluate the expression of intestinal tight junction proteins. Additionally, the expression levels of synaptic proteins, glucose transporters, neurotrophic factors, and inflammatory markers were measured in the hippocampus. Our findings demonstrate that T2DM mice exhibit impaired cognitive function and significant alterations in their gut microbiota compared to non-diabetic controls. Exercise partially reversed these changes in the intestinal microbiota and alleviated cognitive impairment in T2DM mice. Additionally, transplantation of intestinal microbiota from exercised mice improved cognitive function in T2DM mice. Aerobic exercise may mitigate cognitive impairment in T2DM mice by modulating the gut microbiota. The underlying mechanisms appear to involve enhanced neural synaptic plasticity, reduced neuroinflammation, and improved neuronal glucose metabolism.},

abstract = {Parkinson's disease (PD) is a progressive neurodegenerative disorder marked by dopaminergic neuronal loss, α-synuclein aggregation, and sustained neuroinflammation. Emerging evidence supports the gut-brain-microbiota axis as a pivotal player in the disease's pathogenesis. Dysbiosis, disruptions in the gut microbial composition, has been consistently observed in individuals with PD, with notable reductions in beneficial, short-chain fatty acid-producing bacteria and elevations in pro-inflammatory microbial species. These alterations contribute to increased intestinal permeability, systemic inflammation, and heightened neuroinflammatory responses that may drive α-synuclein misfolding and dopaminergic degeneration. In addition, microbial metabolites, including lipopolysaccharides and amyloid proteins such as curli, may promote neurodegeneration via immune and molecular mimicry pathways. Recent advances highlight the bidirectional influence of the microbiota-gut-brain axis on PD symptoms, ranging from motor deficits to non-motor features like constipation, depression, and cognitive decline. Several microbiota-modulating interventions, including probiotics, prebiotics, dietary strategies, antibiotics, and fecal microbiota transplantation, have demonstrated neuroprotective potential in both preclinical and clinical contexts. However, inter-individual variability, methodological heterogeneity, and the absence of longitudinal, multi-omics-integrated studies limit current understanding. The gut microbiome also holds promise as a non-invasive biomarker for early PD detection and prognosis, though standardization remains a challenge. Future research must clarify causal mechanisms, optimize therapeutic delivery, and integrate genetic, metabolic, and environmental data to advance precision medicine approaches. This review consolidates current knowledge on gut microbiota's role in PD pathophysiology and therapeutic innovation, providing a roadmap for future research directions.},

abstract = {Betaine is a growth-promoting additive used in both the animal production and microbial fermentation industries. The primary mechanisms by which betaine promotes animal growth are well known through its direct action on the host cells. However, it remains unclear whether betaine exerts its growth-promoting effects in chickens dependent on the gut microbiota. Here, we found that betaine promotes the growth of broiler chickens while enhancing the richness and diversity of the cecal microbiota and increasing beneficial bacteria, such as Lactobacillus, Limosilactobacillus, and Prevotella (P < 0.05). However, the growth-promoting effects of betaine were abolished in broilers treated with an antibiotic cocktail. Furthermore, fecal microbiota transplantation from betaine-supplemented chickens could recapitulate the promoting effect of betaine on body weight, breast muscle weight, and hepatic insulin-like growth factors (IGFs) synthesis (P < 0.05), indicating that the gut microbiota plays an indispensable role in betaine's growth-promoting action. Mechanistically, betaine promotes (P < 0.05) the synthesis of bile acids, and microbial function predictions suggest that betaine upregulates the biosynthetic pathways of primary and secondary bile acids. Notably, the expression of the bile acid receptor farnesoid X receptor (FXR) was upregulated (P < 0.05) in the liver, promoting FXR binding to the IGFs genes promoter regions and activating the transcription of IGFs gene. Taken together, our findings suggest that betaine promotes broiler growth via microbiota-dependent mechanisms, accompanied by FXR-mediated upregulation of IGFs gene expression in the liver, providing new perspectives and theoretical support for understanding the complexity of animal growth regulation.},

This study aimed to evaluate the efficacy and safety of washed microbiota transplantation (WMT) in managing TKI-induced GAEs. This prospective study involved cancer patients presenting TKI-induced GAEs. The primary outcome was the clinical remission rate at Week 8 post-WMT, which was assessed by the common terminology criteria for adverse events grade. The secondary outcomes included the clinical asymptomatic rate, the onset time of clinical remission, and the variation of C-reactive protein (CRP) levels. Twenty-four patients undergoing 66 WMTs were analyzed. The overall clinical remission and asymptomatic rates were 75.00% (18/24) and 29.17% (7/24), respectively. GAEs, including diarrhea, abdominal pain, and abdominal distention, showed significant improvement post-WMT (all p < .05), while hematochezia exhibited a decreasing trend in severity. Median time to remission was 14.5 days (inter-quartile range, 7-24). Within 8 weeks post-WMT, three initially responsive patients experienced relapse. CRP levels significantly decreased (p < .05), and no severe adverse events were reported. This study proposes WMT as a potential treatment for TKI-induced GAEs, particularly for patients who do not respond adequately to conventional treatments.},

Chronic suppressive antibiotic therapy can be used for preventive purposes, but it is associated with adverse effects and can select resistant bacterial strains. Fecal microbiota transfer (FMT) has been shown to be effective in preventing recurrent Clostridioides difficile infection and could be a useful strategy in patients with RAC.

OBJECTIVE: To review the experience of the use of FMT in the prevention of episodes of RAC by reviewing published cases.

RESULT: Four cases were identified in which FMT significantly reduced RAC episodes. The patients were characterized by lack of efficacy of conventional treatments, had different predisposing factors for RAC and frequent colonization and infection by multidrug-resistant bacteria.

CONCLUSIONS: The four cases presented provide limited but encouraging evidence of the preventive effect of FMT on successive episodes in patients without biliary tract obstruction. Larger and more adequately designed studies will be necessary to deepen the knowledge of this possible preventive strategy.},

abstract = {Recurrent pregnancy loss (RPL) significantly affects reproductive health in couples of childbearing age. Its pathogenesis is complex, with nearly 50% of cases remaining unexplained, and immune regulation plays a key role in its development. This review focuses on the relationship between human microbiota (gut, reproductive tract, and endometrial microbiota), immune regulation, and RPL, systematically summarizing related research progress. RPL patients exhibit characteristic changes in the gut, reproductive tract, and endometrial microbiota, such as reduced gut microbial diversity, decreased beneficial bacteria, increased harmful bacteria in the reproductive tract, and an imbalanced endometrial microbiota structure. Dysbiosis can lead to immune regulation abnormalities, increasing the risk of RPL by disrupting immune tolerance, triggering inflammatory responses, and interfering with metabolism. Although microbiota-based interventions, such as probiotics, prebiotics, and fecal microbiota transplantation, show potential, they face challenges related to strain selection, donor screening, and unclear mechanisms. Current research also faces limitations in detection technology and sample size, and the understanding of the microbiota-immune-RPL relationship requires further deepening. Future studies should clarify causal relationships using advanced technologies, develop more effective detection and intervention methods, and create personalized treatment plans based on individual patient characteristics to improve clinical diagnosis and treatment of RPL and safeguard women's reproductive health.},

abstract = {BACKGROUND: Drug-induced liver injury (DILI) is a major clinical concern due to its unpredictable nature and lack of effective therapeutic options.

METHODS: This study investigated the hepatoprotective effects of Atractylodes macrocephala polysaccharides (AMPs) in a mouse model of acetaminophen (APAP)-induced liver injury. Mice were pretreated with AMPs for 7 days prior to APAP challenge, and liver injury was evaluated through histopathology, serum biochemistry, molecular assays, and gut microbiota analysis.

RESULTS: AMPs treatment significantly reduced serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels compared to the APAP group (p < 0.05). Hepatic oxidative stress was alleviated, as indicated by increased levels of glutathione (GSH, p < 0.05) and superoxide dismutase (SOD, p < 0.05), and reduced malondialdehyde (MDA, p < 0.05). AMPs also suppressed inflammatory cytokines, including Il-1β, Tnf-α, Il-6, and Nlrp3 (p < 0.05), and modulated apoptosis-related proteins by downregulating Bax and upregulating Bcl-2 and Bcl-xl expression (p < 0.05). Furthermore, AMPs improved gut microbiota diversity and enriched beneficial genera such as Roseburia, as revealed by 16S rDNA sequencing. Fecal microbiota transplantation from AMPs-treated mice replicated these hepatoprotective effects, highlighting the involvement of the gut-liver axis.

CONCLUSION: These findings support the therapeutic potential of AMPs as a multifaceted agent for DILI, exerting protective effects through modulation of oxidative stress, inflammation, apoptosis, and intestinal dysbiosis.},

abstract = {BACKGROUND: Gut microbiota has demonstrated an increasingly important role in the onset and development of type 2 diabetes mellitus (T2DM), Further investigations have revealed the interactions between drugs and the gut microbiome. However, there are still gaps in research regarding the potential interactions between the gut microbiota and GLP-1 and their therapeutic response in people with T2DM. In addition, Fecal microbiota transplantation (FMT) has become a promising strategy for patients with T2DM.

50 healthy male C57BL/6 mice were fed a high-fat diet in combination with STZ to establish a T2DM mouse model. 40 mice were divided into the T2DM group (n=10) and the PEX168 group (n=30). the PEX168 group was divided into two subgroups of the IE group (HbA1c ≤6. 5%, n=12) and the SE group (HbA1c >6. 5%, n=12), 12 mice in each group. Using IE mice as fecal donors and SE mice as recipients, fecal microbiota transplantation was performed between the two groups, the FMT group (given fecal bacterial suspension, n=5) and the Sham group (given equal amounts of sterile saline, n=5). The intestinal microorganisms of mice in the IE group (donor) and SE group (recipient) were also analyzed for differences. To assess the protective effect of FMT on drug efficacy and T2DM, and to explore the underlying mechanisms.

RESULTS: After 10 weeks, compared with the control group, the HbA1c of the experimental group was significantly reduced, still, the level of HBA1c of the mice in the unsatisfactory group was significantly higher than that in the ideal group. Compared with the unsatisfactory group, fasting blood glucose, 2h postprandial blood glucose, blood glucose AUC and body weight were significantly reduced in the ideal group. 16srDNA sequencing showed that the levels of Bacteroidota, Akkermansia, Parabacteroides, Bifidobacteria and other bacteria in the ideal efficacy group were significantly higher than those in the non-ideal efficacy group (P<0.05). The levels of Firmicutes, Romboutsia, Clostridium, Turicibacter and other bacteria in the unsatisfactory group were significantly higher than those in the ideal group (P<0.05). The dominant flora of mice in the ideal drug efficacy group was negatively correlated with HbA1c and blood sugar, and the dominant flora of mice in the unsatisfactory drug efficacy group was positively correlated with pro-inflammatory factors such as blood sugar. Moreover, FMT treatment significantly improved the efficacy of PEX168 and liver steatosis in the group with unsatisfactory efficacy.

CONCLUSION: In summary, we used the combined method of 16S rDNA and metabolomics to systematically elucidate the efficacy of microflora on PEX168 and the possible mechanism of FMT in treating T2DM by PEX168. The difference in intestinal flora between individuals can affect the therapeutic effect of drugs. Moreover, FMT therapy can affect multiple metabolic pathways and colonization of beneficial bacteria to maintain the drug's therapeutic effect on T2DM mice.},

In this study, administration of ginseng neutral polysaccharide (GPN) is found to alleviate gut leak and low-grade inflammation, concomitantly with improving the physiological function aged mice. Fecal microbiota transplantation and fecal conditioned medium are used to assess the specific involvement of gut bacterial metabolites in the effects of GPNs. Comprehensive multi-omics analyses showed that GPN significantly enriched the abundance of Alistipes senegalensis, an indole-producing commensal bacterium. Increased expression of tight junction-associated proteins, as well as activation of gut stem cells, are found to be mediated by the AhR pathway, indicating the causal mechanism by which GPN reduced increases in gut permeability. The results are verified in Caco-2/THP-1 cells, Caenorhabditis elegans, and enteroids. To the knowledge, this is the first identification of an integral functional axis through which GPN and functional metabolites of A. senegalensis influence the gut barrier and reduce systemic inflammation, providing clues for the potential development of innovative plant polysaccharide treatment strategies to promote healthy aging.},

abstract = {BACKGROUND: Bile acids and gut microbiota participate in the pathogenesis of liver fibrosis (LF). The total alkaloids of Corydalis saxicola Bunting (TACS) is a traditional Chinese medicine extract that has been used to treat LF, but the underlying mechanisms are not clear. This study performed integrated metabolomics and gut microbiome analysis to study the anti-LF mechanism of TACS using a rat model.

METHODS: Ultra-performance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS) was used to identify the chemical compounds in TACS. Biochemical and histopathological analysis were performed to determine the efficacy of TACS. Bile acid-targeted metabolomics was used to assess changes in the bile acid (BA) profiles in TACS-treated LF rats. 16S rRNA gene sequencing and metagenomics were used to assess changes in the gut microbiota of the TACS-treated LF rats. Antibiotic cocktail treatment and fecal microbiota transplantation (FMT) were used to determine the relationship between the gut microbiota and the anti-LF effects of TACS. Metagenomics was used to identify significantly enriched gut microbiota after TACS treatment and its correlation with the anti-LF effects was verified by in vivo experiments.

RESULTS: TACS treatment significantly reduced the levels of serum liver enzymes, fibrosis and pro-inflammatory cytokines in the liver. TACS significantly increased the levels of chenodeoxycholic acid (CDCA) and taurochenodeoxycholic acid (TCDCA) in the cecum and decreased the levels of cholic acid (CA) and deoxycholic acid (DCA) in the liver of the LF rats. TACS significantly increased the abundances of Lactobacillus and Akkermansia in the LF rats. Antibiotic cocktail treatment and FMT have shown that the effect of TACS cure liver fibrosis depends on the gut microbiota. The abundance of Lactobacillus reuteri was significantly increased by TACS. Administration of Lactobacillus reuteri via gavage ameliorated LF.

CONCLUSIONS: TACS exerted anti-LF effects in rats by modulating bile acid metabolism and gut microbiome.},

abstract = {BACKGROUND: Recent guidelines recommend fecal microbiota transplantation (FMT) for patients who experience multiple episodes of Clostridioides difficile infection (CDI). The availability of lyophilised and encapsulated FMT in recent years has greatly improved patient comfort and convenience. While the effectiveness of FMT in oral capsules seems comparable to that achieved through other routes, further experience is needed, particularly in Europe, where there is currently limited published experience. The objective of this study was to present our experience with this therapeutic modality.

METHODS: A retrospective cohort study on patients with recurrent CDI treated by lyophilised, encapsulated FMT. All patients were followed for a minimum of 12 weeks. The primary outcome was recurrence at three months.

RESULTS: A total of 36 patients received 38 FMTs. The median age of the cohort was 78.5 years, with a median of four previous episodes. At the three-month follow-up, 27 of the 36 patients (75.0%) were free of CDI. One patient exhibited recurrence before the six-month mark. Two of the ten patients with FMT failure were successfully rescued with a second FMT. Of the nine patients who underwent rescue attempts, seven did not experience recurrence, resulting in a cure rate of 91.7% for the 36 patients. We did not detect severe adverse effects related to the FMT.

CONCLUSION: We confirm an acceptable effectiveness of lyophilised capsulated oral FMT. Interestingly, most patients with FMT failure can be cured with a new treatment, which need not necessarily be a new FMT.},

abstract = {Bloodstream bacterial infections cause one-third of deaths from bacterial infections, and eradication of circulating bacteria is essential to prevent disseminated infections. We here found that hepcidin, the master regulator of systemic iron homeostasis, affected Kupffer cell (KC) immune defense against bloodstream bacterial infections by modulating the gut commensal bacteria-derived tryptophan derivative indole-3-propionic acid (IPA). Hepcidin deficiency impaired bacterial capture by KCs and exacerbated systemic bacterial dissemination through morphological changes in KCs. Gut microbiota depletion and fecal microbiota transplantation revealed that the gut microbiota mediated the alteration of KCs volume. Mechanistically, hepcidin deficiency led to a decreased abundance of the IPA-producing commensal Lactobacillus intestinalis and a concomitant reduction in the gut-to-liver shuttling of its metabolite IPA. IPA supplementation or Lactobacillus intestinalis colonization restored the KC volume and hepatic immune defense against bloodstream bacterial infection in hepcidin-deficient mice. Moreover, hepcidin levels in patients with bacteremia were associated with days of antibiotic usage and hospitalization. Collectively, our findings described a previously unappreciated role of hepcidin in sustaining KC-mediated hepatic defense against bloodstream bacterial infections through the gut commensal Lactobacillus intestinalis and its tryptophan derivative IPA. More importantly, restoring the crosstalk between the gut microbiota and liver through IPA-inspired therapies may offer a promising strategy for enhancing the host defense against bloodstream bacterial infections in those with low hepcidin levels and a high risk for bacterial infections.},

Icariin has been shown to effectively modulate hepatic lipid metabolism in male piglets with intrauterine growth restriction. However, the role of gut microbiota in this process remains to be elucidated. This study aimed to explore the influence of gut microbiota on icariin-induced enhancement of hepatic lipid metabolism. By examining changes in microbiota composition and hepatic lipid metabolism following icariin intervention, the study demonstrated an association between microbial alterations and hepatic lipid regulation through fecal microbiota transplantation. The impact of Catenibacterium on gut microbiota structure and hepatic lipid metabolism was assessed in vivo, and the direct effect of icariin on Catenibacterium was explored in vitro. Results revealed that icariin intervention modified fecal, ileal, and colonic microbiota in male piglets with intrauterine growth restriction, enhanced gut morphology and barrier function, and normalized the expression of hepatic peroxisome proliferator-activated receptor (PPAR) signaling pathway-related genes. Fecal microbiota transplantation from piglets with intrauterine growth restriction impaired intestinal barrier function and led to hepatic lipid deposition, whereas transplantation from icariin-treated donors showed no pathological changes, an outcome associated with reduced abundance of Catenibacterium. Mechanistically, icariin inhibits adenosine triphosphate synthesis to suppress Catenibacterium, remodels gut microbiota, reduces lipopolysaccharide production and translocation, and activates the hepatic PPARα/CD36 axis. In conclusion, icariin intervention alleviates hepatic lipid metabolic disorders in male offspring with intrauterine growth restriction by suppressing Catenibacterium, restoring gut microbial balance, and enhancing intestinal barrier integrity to limit lipopolysaccharide translocation.},

In some cases, NAFLD may lead to liver inflammation and non-alcoholic steatohepatitis, which can eventually progress to liver cirrhosis and hepatocellular carcinoma. The pathophysiology of NAFLD is complex, involving both genetic and environmental factors. NAFLD is a multisystem disease linked to a higher likelihood of developing metabolic disorders such as type 2 diabetes, obesity, and cardiovascular and chronic kidney diseases. The gut-liver axis represents a key connection between the gut microbiota and the liver, and its disruption has been linked to NAFLD. Growing evidence underscores the significant role of gut microbiota in the onset and progression of NAFLD, with alterations in the gut microbiome and impaired gut barrier function. Studies have identified key microbiota signatures and metabolites linked to NAFLD, implicating oxidative stress, endotoxemia, and inflammatory pathways that further strengthen the connection between gut microbiota and NAFLD. Modulation of gut microbiota through diet and microbiota-centered therapies, such as next-generation probiotics and fecal microbiota transplantation, holds promise for treating NAFLD. In this review, we explore the key link between gut microbiota and the development and progression of NAFLD, as well as its potential applications in the diagnosis and treatment of the disease.},

This study therefore aimed to analyze the current status and extent of research and areas of interest in the study of FC with anxiety or depression.

METHODS: Data from studies on FC with anxiety or depression, that were performed between 2003 and 2024, were retrieved from the Web of Science Core Collection database. Data regarding the annual number of publications, authors, countries, and references were assessed using CiteSpace v6.3.R1 (64-bit) and Microsoft Excel, and those pertaining to keywords and cited authors were evaluated using VOSviewer 1.6.20. The co-occurrence and clustering functions were then used to generate visual knowledge maps.

RESULTS: The overall annual publication volume demonstrated an upward trend between 2003 and 2024; this was indicative of promising research prospects. The 427 publications identified included 6 types of papers, among which original research articles represented the highest proportion (357 [83.61%] articles published across 200 journals). Neurogastroenterology and Motility had the highest publication volume (30 articles, 7.02%). The United States of America had published most of the papers (135 articles, 31.61%) on the topic. Harvard University was the research institution with the most published papers (21 articles, 4.92%), and Michel Bouchoucha had authored the highest number of articles (13 articles, 3.04%).

CONCLUSION: Future studies in the field of basic medicine need to determine the etiology and pathogenesis of FC with anxiety or depression; in particular, they need to evaluate the role of opioid drugs as a key etiological factor. The role played by the brain-gut axis also warrants investigation. From the clinical perspective, studies need to focus on evidence-based medicine; particular emphasis needs to be placed on randomized double-blind controlled trials with stringent quality control, high-quality meta-analyses, and evaluation of questionnaires and scales. Treatment techniques need to be explored in greater detail; in this context, it is recommended that fecal microbiota transplantation and biofeedback therapy are adopted in the clinic. Furthermore, Patients with FC, especially those with a history of anxiety or depression, tend to have overlapping dyspepsia symptoms.},

abstract = {BACKGROUND: Clostridioides difficile infection (CDI) causes high morbidity and mortality. Faecal microbiota transplantation (FMT) is well-established for CDI, but therapeutic strategies may be optimised. We aimed to evaluate clinical outcomes by analysing therapeutic strategies in a real-life cohort of patients with CDI treated with FMT.

METHODS: We conducted a multi-site cohort study, including 1170 patients with CDI, treated with FMT through capsules, colonoscopy, or nasojejunal tube between May 2016 and December 2023. The primary outcome was cure of C. difficile-associated diarrhea (CDAD) eight weeks after treatment. We investigated antibiotic pretreatment type and length, FMT dosing and administration, and post-FMT prophylactic vancomycin during non-CDI antibiotic use, applying multivariable mixed-effect regression analysis including the patient as a random effect. The study was preregistered at ClinicalTrials.gov, NCT03712722.

FINDINGS: The 1170 patients received 1643 FMT treatments. Patients' median age was 71 years (interquartile range 56-80 years). Following their first FMT treatment, 699 patients (60% (95% confidence interval: 57-63%)) were cured of CDAD. After repeated FMT treatments, 944 patients (81% (78-83%)) were cured. Prolonged antibiotic pretreatment was associated with higher cure rates (65% (59-70%), odds ratio (OR): 1.22 (1.10-1.36), p < 0.001). FMT administration through oral, multi-dose capsules (69% (63-74%), OR: 1.19 (1.11-1.27), p < 0.001) or colonoscopy (69% (61-76%), OR: 1.14 (1.04-1.24), p = 0.01) resulted in the highest cure rates. Neither antibiotic pretreatment type nor prophylactic vancomycin during non-CDI antibiotics affected cure rates. In patients for whom FMT was initially unsuccessful, repeated FMT was more effective than antibiotic treatment alone.

INTERPRETATION: CDI outcomes could be improved by optimising antibiotic pretreatment duration, selecting appropriate FMT delivery methods, and repeating FMT.

abstract = {Fecal Microbiota Transplant (FMT) is a treatment for recurrent Clostridium difficile infections and is being explored for other clinical applications, from alleviating digestive and neurological disorders, to restoring microbiomes impacted by cancer treatment. Quantifying the extent of engraftment following an FMT is important in understanding a recipient's response to treatment. Engraftment and clinical response need to be investigated independently to evaluate an FMT's role (or lack thereof) in achieving a clinical response. Standardized bioinformatics methodologies for quantifying engraftment extent would not only improve assessment and understanding of FMT outcomes, but also facilitate comparison of FMT results and protocols across studies. Here we review FMT studies, integrating three concepts from microbial ecology as framework to discuss how these studies approached assessing engraftment extent: 1) Community Coalescence investigates microbiome shifts following FMT engraftment, 2) Indicator Features tracks specific microbiome features as a signal of engraftment, and 3) Resilience examines how resistant post-FMT recipients' microbiomes are to reverting back to baseline. These concepts explore subtly different questions about the microbiome following FMT. Taken together, they provide holistic insight into how an FMT alters a recipient's microbiome composition and provide a clear framework for quantifying and communicating about microbiome engraftment.},

abstract = {BACKGROUND: Endoscopic examinations are increasingly used in veterinary medicine. Examination using flexible endoscopes is limited to the anterior gastrointestinal tract (panendoscopy) and colon (colonoscopy), while a significant part of the small intestine remains unexamined. Capsular endoscopy is increasingly used, allowing macroscopic assessment of the entire digestive tract. The current study assessed the effect of prokinetic drugs on transit time and cleanliness of the tested part of the digestive tract in capsule endoscopy.

METHODS: The study aimed to evaluate the usefulness of two prokinetic drugs (metoclopramide and cisapride) in capsule endoscopy studies while assessing the quality of the macroscopic image. Each animal included into the study had endoscopic examination three times - without the administration of prokinetic drugs, after receiving metoclopramide and after receiving cisapride.

RESULTS: The total passage time of the capsule through the gastrointestinal tract was the longest in the group receiving metoclopramide (691.33 min) and the shortest in the group receiving cisapride (584.17 min). The best quality images were observed in the control group.

CONCLUSION: This research has confirmed the hypothesis that administration of prokinetic drugs increases the probability of recording the entire macroscopic image of the gastrointestinal tract during endoscopy in dogs. A negative feature of their administration is significantly reduced recording quality because of the level of cleanliness of the tested gastrointestinal section.},

abstract = {Ulcerative colitis (UC) is a chronic, non-specific inflammatory disease of the intestines with a significant increase in global incidence in recent years. Oxidative stress and inflammation are two hallmarks of UC pathogenesis. Anemoside B4 (AB4), a pentacyclic triterpenoid saponin, exhibits significant antioxidant and anti-inflammatory properties and shows potential for preventing UC. Here, an animal model induced by dextran sodium sulfate (DSS) was used to investigate the effect of AB4 on UC. The results demonstrated that AB4 significantly reduces intestinal oxidative stress and inflammation in UC mice, while also protecting intestinal barrier function. Furthermore, AB4 helps restore intestinal microbial balance primarily by modulating the abundance of Lactobacillus, which enhances the metabolism of short-chain fatty acids and upregulates the production of butyric acid (BA). Pseudogerm-free mice and fecal microbiota transplantation (FMT) demonstrated that AB4 significantly mitigated UC in a gut microbe-dependent manner. Both AB4 and BA markedly activate the aromatic hydrocarbon receptor (AhR). The intestinal organoid results suggest BA may activate the AhR to inhibit ROS production and activation of NLRP3 inflammasome, thereby protecting intestinal integrity. Administration of AhR antagonists abolished the protective effects, thus confirming the involvement of AhR in the underlying mechanism. Overall, these results indicate that AB4 is an effective agent against UC mainly by activating the AhR through gut microbial short-chain fatty acid metabolites to inhibit intestinal oxidative stress and inflammation.},

Growing evidence from animal studies has shown that some specific probiotics can alleviate CMA, but clinical evidence remains insufficient due to certain limitations. In the present study, we transplanted fecal material from three CMA children into antibiotic-pretreated mice (hum-CMA mice) to mimic the intestinal microecology of allergic individuals, followed by allergen sensitization and Bifidobacterium breve (B. breve) M-16V intervention. Our results showed that B. breve M-16V effectively ameliorated CMA symptoms and allergy-related indicators in hum-CMA mice. Moreover, B. breve M-16V differentially affected the composition of intestinal microbes, but the abundance of beneficial bacteria, such as short-chain fatty acid-producing bacteria, was consistently elevated in all three groups of hum-CMA mice. Subsequent untargeted metabolomics analyses revealed that B. breve M-16V improved the pattern of serum metabolites, and these differential metabolites were mainly involved in glutathione metabolism, glycerophospholipid metabolism, and tryptophan metabolism. All the findings indicate that B. breve M-16V can alleviate the anaphylactic reaction in hum-CMA mice by regulating the intestinal microbiota and metabolites, providing a valuable scientific basis for the clinical application of probiotics in food allergy.},

While current treatments such as surveillance, surgery, and radiation are effective, they have their limitations. These can include patient incompliance due to side effects or resistance to hormonal changes, highlighting the need for alternative approaches. Human microbiota, a complex and dynamic host, plays a significant role in the homeostasis and is associated with several diseases or cancers in cases of dysregulation and dysbiosis. Research on fecal microbiota profiling and its association with certain cancers has opened new possibilities for preventing and managing tumor progression. One such possibility is fecal microbial transplantation (FMT). Studies show that different composition of urinary microbiota is found in various urinary tract diseases. Gut microbiota can regulate immune response against tumors; therefore, FMT may help modulate gut microbiota in a way that potentially enhances responses to immune checkpoint inhibitors, as suggested by emerging evidence in other cancers, though this needs further validation in PCa. Nevertheless, long-term complications and the safety of FMT are still questioned. We reviewed the roles of gut microbiota in PCa and suggested FMT as a potential tool in the treatment of PCa, which needs further investigations.},

abstract = {Introduction Clostridioides difficile infection (CDI) is a leading cause of healthcare-associated diarrhea with a significant risk of recurrence, posing challenges for patient management and infection control. Identifying risk factors for recurrence is essential to improve outcomes and prevent relapses. Methods This retrospective cohort study included 860 adult patients (≥18 years) treated with vancomycin for CDI at Johns Hopkins Aramco Healthcare (JHAH) in Dhahran, Saudi Arabia, between January 2015 and December 2020. Patients with confirmed CDI based on stool polymerase chain reaction (PCR) or toxin assays, complete medical records, and adequate follow-up data were included. The study excluded those not treated with vancomycin, under 18 years of age, with incomplete records, those who received fecal microbiota transplantation or experimental treatments, and those lacking follow-up data. Data on demographics, comorbidities, hospitalization, medication use, and recurrence were analyzed using univariate and multivariate logistic regression models. Results Univariate analysis showed that age 40-65 years (OR = 1.53; 95% CI: 1.024-2.285; p = 0.038), age >65 years (OR = 1.894; 95% CI: 1.282-2.799; p = 0.001), cirrhosis (OR = 9.104; 95% CI: 1.233-67.192; p = 0.03), hospitalization (OR = 1.974; 95% CI: 1.417-2.749; p < 0.0001), and type 2 diabetes mellitus (OR = 1.65; 95% CI: 1.106-2.462; p = 0.014) were significantly associated with CDI recurrence. After adjusting for confounders, only hospitalization remained a statistically significant independent predictor (OR = 1.597; 95% CI: 1.098-2.325; p = 0.014). Conclusion Hospitalization was identified as the most significant independent risk factor for CDI recurrence. These findings highlight the need for enhanced infection control practices and close monitoring of hospitalized patients with CDI. Future prospective and multicenter studies are recommended to validate these results and explore additional modifiable risk factors to reduce recurrence rates.},

abstract = {BACKGROUND: The 2021 Infectious Diseases Society of America (IDSA) and Society for Healthcare Epidemiology of America (SHEA) guidelines for Clostridioides difficile infection (CDI) introduced new recommendations for managing initial and recurrent CDI. Since then, new microbiome-based therapies for preventing recurrent CDI have become available. We surveyed infectious diseases (ID) clinicians to understand their experiences, practices, and challenges in CDI management.

METHODS: An electronic survey was distributed to members of the IDSA Emerging Infections Network in May 2024, targeting ID physicians and healthcare professionals in the United States who manage adult CDI. The survey assessed treatment preferences, clinical practices, and barriers to accessing and prescribing CDI therapies.

RESULTS: Of the 500 respondents who reported treating CDI in the past year, 83% (417/500) indicated that vancomycin was their most frequently prescribed agent for initial, nonfulminant CDI. Additionally, 72% (357/498) reported that their institutional guidelines recommended vancomycin as the first-line agent. The most common barrier to fidaxomicin use was challenges with outpatient insurance coverage (82% [408/496]). Bezlotoxumab was available to 74% (370/500) of respondents, though 33% (165/497) indicated they do not use bezlotoxumab routinely. Most clinicians (87% [437/500]) had previously recommended fecal microbiota transplantation (FMT) for recurrent CDI, though only 48% (239/500) had current access to FMT using donor stool. Fecal microbiota live-jslm was available to 36% (179/500), and fecal microbiota spores live-brpk was available to 30% (150/500).

CONCLUSIONS: Significant barriers, including high costs, insurance challenges, and limited availability of CDI therapies, impact clinical decision-making and adherence to guideline recommendations.},

Our findings revealed that FGE significantly attenuated PTZ-induced insomnia behavior, circadian rhythm disturbances, and compromised gut barrier functions. Mechanistically, gut microbiota and 5-HT within the microbiota-gut-brain axis are the key regulators in short-term SD. Fecal microbiota transplantation (FMT) experiment identified gut microbiota as a key mediator and potential therapeutic target for FGE. The comprehensive analysis of 16S rRNA sequencing and metabolomic analysis showed that amino acid metabolism-related pathways as key factors of FGE intervention. Notably, omics joint analysis demonstrated a strong association between the variations of the intestinal microbiota among different groups and the notable alterations in the brain metabolomic landscape. Meanwhile, the remodeling of intestinal microbial structure and metabolites drove the homeostasis of 5-HT levels in different tissues. Importantly, exogenous keystone bacteria supplementation to sleep-deprived zebrafish restored insomnia responses and amino acid metabolism. Targeted amino acid metabolism further confirmed amino acid metabolism as the central mechanistic pathway through which FGE exerts its protective function. Collectively, Collectively, these findings suggested that FGE showed a significant preventative action on short-term SD by intervening gut microbiota and amino acid metabolism in zebrafish to promote 5-HT homeostasis, which offers perspectives into new preventive strategies of traditional Chinese medicine dietary supplements for transient insomnia.},

A clinical study has reported that the intestine of a chronic hepatitis E patient is positive for HEV. However, whether the intestinal epithelium acts as a barrier for HEV transmission or whether productive enteric infection enhances transfer of the virus to the liver remains unclear. The advent of organoid technology provides a valuable platform for advancing the study of HEV-host interactions in a more physiologically relevant context. In this study, we demonstrate that primary human intestinal organoids (HIOs) efficiently support HEV replication. The infection was sustained in differentiated HIOs with specific phenotypes of intestinal cell types, namely enterocyte, goblet cell, and enteroendocrine cell lineages. Next, we constructed a gut-liver axis model using a transwell system by co-culturing HIOs with human liver-derived organoids. Importantly, infectious viral particles produced in HIOs were capable of transmission to human liver-derived organoids in this model. Bile acids are essential mediators of gut-liver crosstalk. We found that supplementing human bile or the primary bile acid chenodeoxycholic acid inhibited HEV replication in organoids via the farnesoid X receptor (FXR) signaling pathway. The effects of the secondary bile acid, ursodeoxycholic acid, were opposite and promoted viral replication. In conclusion, this model provides a novel approach to study the gut-liver axis in HEV transmission and the impact of bile acids in modulating HEV infection.},

Gut senescence and altered environmental factors contribute to changes in the intestinal metabolome, particularly in frail older individuals. However, the role of age-associated dysbiosis, characterized by a decline in beneficial gut microbiota and their metabolites, in exacerbating IBD remains unclear.

METHODS: To investigate the impact of aging-associated dysbiosis on colitis development, we employed fecal microbiota transplantation (FMT) in wild-type and IL-10-deficient mice. Aged mice were treated with gut microbiota from either young or aged mice and then subjected to dextran sulfate sodium (DSS) to induce experimental colitis. 16S rDNA sequencing and metabolomics were used to analyze microbial and metabolite profiles. Single-cell RNA sequencing (scRNA-seq) was performed to characterize lamina propria CD45[+] immune cell composition.

RESULTS: Aged mice receiving microbiota from young mice exhibited less severe colitis than those receiving microbiota from aged mice, as evidenced by reduced disease activity, weight loss, and colonic shortening. Besides, aged mice displayed a significant decrease in the Lactobacillus population, accompanied by a reduction in Nordihydroguaiaretic acid (NDGA) levels. Decreased fecal NDGA levels were also observed in both IBD patients and elderly individuals. Administration of NDGA alleviated experimental colitis by downregulating the GSDMD/NR4A1/NLRP3 axis-mediated macrophage pyroptosis. Deletion of GSDMD in macrophages significantly diminished the protective effect of NDGA on colitis.

CONCLUSIONS: Our findings demonstrate that aging is associated with dysbiosis and reduced NDGA production, which increases susceptibility to intestinal inflammation. Gut microbial NDGA exhibits potential anti-inflammatory activity in colitis, suggesting a promising therapeutic target for aged-related IBD.},

abstract = {Many diseases are influenced by environmental temperature, and recent studies have confirmed that cold exposure increases the risk of conditions such as ischemic stroke (IS). However, direct evidence supporting this hypothesis is lacking, and the molecular mechanisms through which cold exposure affects IS remain unclear. In this study, we found that chronic cold exposure increased platelet aggregation and the levels of certain inflammatory factors in high-risk stroke patients (HR), thereby increasing the risk of IS. Furthermore, before and after a cold wave, we observed gut microbiota dysbiosis in the HR group, including reduced relative abundance differences in Lachnospiraceae and Ruminococcaceae. The relative abundances of the Prevotella_9 and Catenibacterium genera increased, whereas that of Anaerostipes decreased. Notably, the results of fecal microbiota transplantation (FMT) indicated that cold-adapted microbiota transplantation partially replicated the microbiota characteristics of each donor subject and replicated the effects of cold exposure in C57BL/6J mice. Cold exposure impaired intestinal barrier function and interfered with microbial functions, such as increased lipid metabolism and LPS production, particularly by increasing the levels of TMAO derived from the gut microbiota. Our findings identify the significant role of abnormal gut microbiota-derived metabolites in cold exposure-related IS and highlight the potential opportunity to prevent or treat cold-related IS through the modulation of the gut microbiota.},

abstract = {Improving growth performance is vital in poultry production. Although several studies have established associations between gut microbiota and growth, the direct impacts remain unclear. A total of 120 1-day-old Sansui ducks were randomly assigned to the FMT and CON groups. From the 1st day, ducks in the FMT group were orally administrated with 0.5 mL fecal microbiota suspension for three consecutive days, while sterile PBS solution was used as a substitute in the CON group. The results revealed that FMT improved average daily gain (ADG) (P < 0.001) and body weight (BW) (P < 0.001), with a tendency for a better feed conversion rate (FCR) (P = 0.062). LEfSe analysis indicated a significant increase in the abundance of the Lactobacillus (P < 0.001), Bifidobacterium (P = 0.006), Megamonas (P = 0.008), and Subdoligranulum (P = 0.005) in the FMT group. Similarly, the phyla Firmicutes/Bacteroidetes ratio was higher in the FMT group compared to the CON group. Additionally, the ACE, Chao, and Shannon indices were also significantly higher in the FMT group (P < 0.001). To sum up, FMT enhanced growth performance, which could be associated with reducing proinflammatory pathogen colonization in the duck cecum. This modulating effect likely results from increased microbial diversity and the enrichment of beneficial bacteria.},

abstract = {The gut microbiota plays an integral role in maintaining health and regulating various host functions, including immune responses. Fecal microbiota transplantation (FMT) has emerged as a promising therapeutic approach to restore gut microbial balance. Although widely recognized for its efficacy in treating ulcerative colitis (UC), FMT is now being investigated as an adjuvant therapy to enhance the efficacy of immune checkpoint inhibitors (ICIs) in cancer treatment. This review summarizes the clinical applications of FMT in UC treatment and its potential role in cancer immunotherapy. FMT exhibits varying degrees of efficacy in the treatment of UC, with differences in outcomes attributed to variations in administration methods and donor selection. In cancer therapy, FMT has demonstrated the potential to improve ICI responses, particularly in patients with melanoma. However, its effects on other cancers remain unclear. Although FMT holds promise for UC and cancer immunotherapy, challenges such as inconsistent clinical outcomes and methodological variations persist. Standardized protocols and mechanistic studies are crucial to optimize FMT-based therapeutic strategies, and further research is required to establish its efficacy under diverse clinical conditions.},

However, current methods have limited information on microbial structure at the genus level and present challenges during cryopreservation. In this study, we used an edible glycerol stock of fecal batch culture instead of fresh feces to create artificial gut microbiota. Three glycerol stocks, generated through in vitro fecal fermentation with different prebiotic additives (such as fructooligosaccharide, xylan, pectin, and guar gum), were combined. Profiling via 16S rRNA gene amplicon sequencing revealed that the artificial gut microbiota derived from the combined glycerol stocks showed more amplicon sequence variants than those from a single glycerol stock. In the artificial microbiota, relative abundance values of common genera such as Bifidobacterium, Bacteroides, Prevotella, Faecalibacterium, and Escherichia were more than 10 % of those found in the original feces. Other commensal genera such as Collinsella, Anaerobutyricum hallii (formerly Eubacterium hallii) group, Anaerostipes, Blautia, Dorea, Lachnospiraceae UCG-004, and Oscillospiraceae UCG-003 were similarly maintained. Our data indicated that combining glycerol stocks of fecal cultures with different additives in a batch-type gut simulator is a useful option for producing artificial gut microbiota, the taxonomic compositions of which are comparable to those of the original feces.},

Despite advancements in biologic disease-modifying antirheumatic drugs (bDMARDs) and TNF-α blockers, many RA patients still require more effective treatment options. Although genetic and environmental factors play a role in RA development, recent studies have emphasized the influence of the gut microbiota on disease onset and progression. Dysbiosis, or an imbalance in the gut microbial composition, has been linked to immune dysregulation, increased intestinal permeability, and systemic inflammation, all contributing to RA development. Research has revealed changes in the gut microbiome of RA patients, including an increased prevalence of Prevotella copri and a decreased presence of beneficial microbes such as Bifidobacterium, Bacteroides, and Lactobacillus. RA patients exhibit altered metabolite profiles, with reduced levels of short-chain fatty acids (SCFAs), such as acetate, propionate, and butyrate, which are linked to immune regulation and intestinal barrier function. Specific metabolites, such as L-arginine, phosphorylcholine, and arachidonic acid, have potential as RA biomarkers, with predictive value for diagnosis. Therapeutic approaches focusing on the microbiome, including probiotics, fecal microbiota transplantation, and traditional medicines, show promise in alleviating RA symptoms and regulating immune function. This review provides an updated overview of the immunomodulatory effects of the gut microbiome and explores its potential applications in the diagnosis and treatment of RA.},

This review focuses on how modulation of gut microbiota can serves as a therapeutic strategy for NDDs, emphasizing the neuroprotective effects of probiotics. Probiotics are live microorganisms that confer health benefits, and their interaction with gut-microbiota influences neurogenesis, neurotransmitter regulation, and neuroinflammation. Recent advancements, including germ-free animal models, fecal microbiota transplantation (FMT), and diverse probiotic strains, have revealed the underlying mechanisms linking gut health to brain function. Notably, several Lactobacillus and Bifidobacterium species have been shown to exert neuroprotective effects via the upregulation of neurotrophic factors such as brain-derived neurotrophic factor and enhancing mitochondrial function through reducing the impacts of oxidative stress. Interestingly, FMT has exhibited a degree of success in overcoming cognitive impairment and motor deficits in preclinical studies and clinical trials. However, further research is warranted to explore its therapeutic potential in humans. Overall, this review highlights the significant role of gut microbiota in NDDs and advocates for gut-targeted interventions as innovative approaches to mitigate these diseases.},

In China, it was first administered orally in the fourth century for diarrhea and food poisoning under the name "Yellow Soup." It has recently been widely employed in a variety of clinical settings, including cases of Clostridium difficile infection that are recurring and resistant. By replacing the unhealthy intestinal microbiota with a healthy bacterial community, the FMT treatment aims to enhance the intestinal flora. It also looks at neurological conditions where alterations in gut microbiota are prevalent. We have discussed FMT in the context of its use in conditions affecting the nerve system, such as neurological and other conditions (multiple sclerosis, Parkinson's disease, Alzheimer's disease, stroke, epilepsy, Amyotrophic lateral sclerosis, Tourette syndrome, neuropathic pain, Huntington's diseases, etc.), as well as the role of gut microbiota in many neurological disorders.},

Identifying reliable early predictors of therapy response and survival is critical. Plasma metabolomics was conducted on 70 SAH patients (50 responders, 20 non-responders) to identify biomarkers for non-response and early mortality. These findings were validated in a cohort of 153 patients and an independent cohort of 245 using high resolution mass spectrometry, machine learning, and severity indices. Temporal metabolic changes indicated interactions between the host and microbiome, with a focus on inflammation and intestinal permeability. Plasma metabolomics revealed that non-responders had significantly higher urobilinogen levels (3.6-fold change). Additionally, a decrease in alpha/beta diversity and temporal metabolic inactivity characterized non-responders. Plasma urobilinogen levels predicted non-response (AUC>0.97) and identified non-survivors (AUC=0.94) with a threshold of >0.07 mg/ml. Urobilinogen levels correlated with bacterial peptides belonging to Firmicutes and Proteobacteria, neutrophil activation, oxidative stress, and pro-inflammatory cytokine production. These changes contributed to non-response by increasing glucocorticoid receptor β expression and compromising intestinal permeability. Fecal microbiota transplantation decreased urobilinogen levels by reducing bilirubin reductase gene-containing microbiota. Plasma urobilinogen >0.07 mg/ml could predict early mortality, and modulation of the gut microbiome may improve outcomes in SAH patients.},

abstract = {Clostridium difficile (C. difficile) infection (CDI) poses a tremendous clinical challenge, especially in patients with recurrent disease and antibiotic resistance. Fecal microbiota transplantation (FMT) has become a new therapeutic strategy for restoring gut microbiota and decreasing CDI recurrence. The study aims to assess the clinical effectiveness of FMT in adult subjects with recurrent or refractory CDI, determine its effect on gut microbiome diversity, and track safety outcomes and rates of recurrence post-treatment. FMT was compared against standard antibiotic treatments to establish its efficacy in decreasing infection persistence and improving patients' quality of life. This study examines the efficacy, safety, and modulation of microbiota by FMT in an ensemble of 250 patients diagnosed with CDI, with equal gender distribution and a mean age of 55.61. Among the study participants, 131 (52.4%) underwent FMT by various routes of administration, including 66 (25.2%) through colonoscopy, 73 (29.2%) via a nasogastric tube, 60 (24.0%) via enema, and 54 (21.6%) through oral capsule administration. The success rate for FMT was reported as 88 (35.2%), partial success at 74 (29.6%), and treatment failure at 88 (35.2%). CDI recurrence was reported in 130 (52.0%) of patients after FMT. The gut microbiome enhanced diversity, measured in terms of the Shannon Diversity Index, increased significantly from 3.96 before FMT to 5.88 after FMT, thus indicating a favorable impact on gut microbial composition. Furthermore, 132 (52.8%) converted from C. difficile polymerase chain reaction (PCR) toxin positive to negative, corroborating successful pathogen clearance. On secondary outcomes, the quality of life in patients improved in 90 (36%), antibiotic dependence was reduced in 88 (35.2%), and hospitalization was lessened in 72 (28.8%). Inflammatory markers, such as white blood cell (WBC) counts and C-reactive protein (CRP), went downward but did not reach statistical significance. Logistic regression analysis identified age, severity of CDI, and prior exposure to antibiotics as the main predictors for the efficacy of FMT (p < 0.05). It is concluded that FMT is a promising alternative treatment for recurrent CDI through modulation of gut microbiota and decreasing the severity of infection. Future work is, however, required to establish treatment protocols with optimized results for long-term effectiveness and minimized recurrence risks.},

In this study, we used a mouse model of dextran sulfate sodium-induced colitis to investigate the effects of voluntary exercise and its underlying mechanisms. Exercise preconditioning attenuated colitis severity, maintained intestinal barrier integrity, normalized gut microbiota composition, and suppressed NET formation. PAD4 inhibition further enhanced these effects. By contrast, the depletion of the gut microbiota by antibiotics largely abolished the benefits of exercise. Additionally, fecal microbiota transplantation from exercised mice recapitulated these protective effects. These findings elucidate the interplay among exercise, gut microbiota, and PAD4-mediated NET formation. Targeting these pathways may offer promising therapeutic strategies for colitis.},

abstract = {As a common neurodegenerative disease, Parkinson's disease (PD) is typified by α-synuclein (α-syn) aggregation and progressive degeneration of dopaminergic neurons within the substantia nigra. Clinical manifestations encompass motor symptoms and non-motor aspects that severely impair quality of life. Existing treatments mainly address symptoms, with no effective disease-modifying therapies available. The gut microbiota refers to the community of microorganisms that colonize the intestinal tract. The gut microbiota, gut, and brain are all connected via a complicated, mutual communication pathway known as the "gut microbiota-gut-brain axis." Gut microbiota dysbiosis is strongly linked to the onset and course of PD, according to growing data. In individuals with PD, gut dysbiosis correlates with clinical phenotype, disease duration, severity, and progression rates. Mechanistically, gut dysbiosis contributes to PD through enhanced intestinal permeability, increased intestinal inflammation and neuroinflammation, abnormal α-syn aggregation, oxidative stress, and reduced neurotransmitter synthesis. Therefore, focusing on the gut microbiota is regarded as a potentially effective treatment strategy. Fecal microbiota transplantation (FMT) is an emerging approach to modulate gut microbiota, with the goal of recovering microbiota diversity and function by transferring functional intestinal flora from healthy individuals into patients' gastrointestinal tracts. FMT is expected to become a promising therapy of PD and has a broad research and application prospect. Evidence suggests that FMT may restore gut microbiota, ease clinical symptoms, and provide potential neuroprotective benefits. However, the precise therapeutic mechanisms of FMT in PD remain uncertain, necessitating further research to clarify its effectiveness. This review examines alterations in gut microbiota linked to PD, mechanisms through which gut dysbiosis influences the disease, and the latest advancements in FMT research for treating PD, setting the stage for its clinical application.},

The impacts of YG on gut health of chickens infected with Salmonella enteritidis (SE) was investigated through histochemical and immunological methods, along with microbiomics. The role of gut microbiome induced by YG treatment in combating Salmonella infection was explored through FMT. Our findings showed that YG administration significantly ameliorated SE-induced gut impairment by decreasing gut permeability, enhancing intestinal barrier function, inhibiting intestinal inflammation, reducing Salmonella colonization, lowering g_Streptococcus and g_Ligilactobacillus but increasing g_Blautia, g_Bacillus and g_Faecalibacterium relative abundance. Transplantation fecal microbiota from YG-treated healthy donor chickens to antibiotic-treated recipient chicks significantly attenuated gut injury caused by SE infection through decreasing Salmonella colonization and invasion along with intestinal permeability, improving gut morphology, upregulating intestinal tight junction genes and proteins expression, downregulating pro-inflammatory cytokines expression. Additionally, FMT remarkably increased g_Bacteroides and g_Faecalibacterium relative abundances and butyric acid level, decreased g_Ruminococcus-torque-group relative abundance in the cecum.Collectively, we assume that yeast β-glucan alleviated Salmonella-induced gut impairment, a mechanism that is dependent on the gut commensal Bacteroides and Faecalibacterium.},

abstract = {BACKGROUND AND AIMS: Fecal microbiota transplantation is an effective treatment method for recurrent Clostridioides difficile infection. Widely used enteric tube and colonoscopy methods demonstrate excellent efficacy and safety results. Recent data suggest that new fecal microbiota transplantation methods using oral capsules may provide a less invasive approach. In this study, we aimed to compare primary fecal microbiota transplantation efficacy as well as short- and long-term safety of two different administration routes: oral capsules and enteric tube.

METHODS: This retrospective study included 60 consecutive patients who underwent fecal microbiota transplantation for recurrent Clostridioides difficile infection. Thirty participants received 50 oral capsules containing frozen material for a single day and 30 patients received fecal microbiota transplantation via nasoenteric tube. All patients received standard treatment with oral vancomycin 500 mg q.i.d. for at least five days before the procedure. After intervention, patients were followed up for at least six months. Data on Clostridioides difficile infection recurrences and health status were collected and analyzed.

RESULTS: The oral capsules group consisted of 30 patients. Among them, 22 (73.3%) participants experienced resolution of symptoms after a single fecal microbiota transplantation, while eight (26.7%) patients developed recurrent diarrhea within eight weeks. The other 30 patients received treatment via nasoenteric tube. Among them, 24 (80%) patients were cured after a single fecal microbiota transplantation, while six (20%) experienced recurrent disease within eight weeks. The primary efficacy did not show significant differences between the two groups (p=0.85). Throughout the follow-up period, no serious adverse events or fecal microbiota transplantation related deaths were reported in both groups.

CONCLUSIONS: Fecal microbiota transplantation with frozen oral capsules is a safe, less invasive method with comparable efficacy to nasoenteric administration route.},

abstract = {OBJECTIVES: To investigate the therapeutic efficacy and mechanism of pentosan polysulfate (PPS) for cyclophosphamide (CYP)-induced interstitial cystitis/bladder pain syndrome (IC/BPS) in mice.

METHODS: Female C57BL/6 mice (6-8 weeks old) were randomized into control group, PPS treatment (25 mg/kg via gavage for 3 weeks) group, CYP treatment (3 separate intraperitoneal injections at 50 mg/kg in week 4), and CYP+PPS treatment group. Gut microbiota alterations of the mice were analyzed using 16S rDNA sequencing and non-targeted metabolomics. Fecal microbiota transplantation (FMT) was performed in CYP-treated recipient mice and those treated with both CYP and PPS. In the in vitro experiment, LPS-stimulated human bladder epithelial cells (SV-HUC-1) were used to assess the effects of deoxycholic acid (DCA) and TGR5 signaling inhibitor SBI-115 on barrier functions of bladder epithelial cells.

RESULTS: PPS treatment significantly improved the mechanical pain thresholds, restored the urodynamic parameters, and attenuated bladder inflammation and barrier dysfunction in CYP-treated mice. Mechanistically, PPS enriched the abundance of Eubacterium xylanophilum and increased DCA levels in the intestines of CYP-treated mice. FMT experiments confirmed microbiota-dependent therapeutic effects of PPS, shown by reduced bladder pathology in the recipient mice treated with both CYP and PPS. In SV-HUC-1 cells, DCA obviously alleviated LPS-induced inflammation and barrier disruption, and treatment with SBI-115 abolished these protective effects of DCA.

CONCLUSIONS: PPS ameliorates IC/BPS in mice by remodeling gut microbiota to enhance DCA production and activate TGR5 signaling, suggesting a novel microbiota-bile acid-TGR5 axis that mediates the therapeutic effect of PPS and a therapeutic strategy for IC/BPS by targeting gut-bladder crosstalk.},

abstract = {BACKGROUND: Gut microbiota dysbiosis has been associated with the development of rheumatoid arthritis (RA). Fengshining (FSN) is a traditional Chinese medicine decoction that can effectively alleviate RA. However, how FSN modulates the gut microbiota to mitigate RA has not been comprehensively studied. This study evaluated the gut microecological mechanisms underlying FSN's effects on RA, focusing on the impact of gut-derived short-chain fatty acids (SCFAs), specifically butyrate, in RA treatment.

METHODS: The pharmacological effects of FSN on type II collagen-induced arthritis (CIA) in mice were assessed via pathological indicators, metagenomics, and metabolomics analyses. Furthermore, the impact of FSN on gut microbiota and metabolic profiles was also evaluated. Moreover, a pseudo-germ-free CIA model was established to validate whether exogenous butyrate alleviates RA. This study also elucidated whether fecal microbiota transplantation (FMT) from FSN-treated mice could mitigate RA symptoms.

RESULTS: The data showed that FSN markedly alleviated CIA symptoms and reduced serum inflammatory cytokine levels. Metagenomic and metabolomic analyses revealed that FSN-enriched SCFA-producing bacteria, including Butyrivibrio, Faecalicatena, and Lacrimispora. Furthermore, FSN increased the activity of carbohydrate metabolism-related enzymes and upregulated the expression patterns of homologous protein families. Moreover, exogenous butyrate supplementation suppressed pro-inflammatory factors, modulating immune responses, and enhanced intestinal barrier function. Further, Western blot analysis validated that FSN inhibited the HDAC/NF-κB pathway.

CONCLUSION: This study indicated that the gut microecological mechanism of FSN might be associated with its herbal components, which regulate gut microbiota diversity, restore the intestinal barrier, and boost microbial metabolite production. Furthermore, butyrate was observed to modulate intestinal mucosa, inhibit inflammatory responses, repair the intestinal barrier, and mitigate joint damage, thus alleviating RA symptoms.},

abstract = {Fibromyalgia (FM) is a multifaceted chronic pain syndrome, predominantly affecting women, and characterised by a constellation of symptoms including diffuse musculoskeletal pain, fatigue, cognitive impairment and poor sleep quality. Its complex pathophysiology likely involves genetic, environmental and psychosocial factors. Recent studies have raised the possibility that the gut microbiome may influence FM symptoms via the gut-brain axis, although this hypothesis remains unconfirmed. This review aims to explore potential associations between gut microbiome alterations, nutrition, and FM, with particular attention to the limitations of current evidence. While certain studies have reported differences in the gut microbiota composition of patients with FM, these findings are preliminary and often derive from small, heterogeneous cohorts. Likewise, faecal microbiota transplantation studies in animals and limited human trials suggest a possible link to pain sensitivity, but further validation is needed.Nutritional interventions, including prebiotics, probiotics and specific dietary strategies, have shown early promise in modulating gut microbiota and alleviating FM symptoms. Nutrients such as magnesium, selenium and omega-3 fatty acids, as well as antioxidant compounds, may influence pain and inflammation pathways, but definitive clinical recommendations are lacking. Given the emerging nature of this field, larger and better-controlled studies are required to clarify the role of the gut microbiome and nutrition in FM. A multidisciplinary management strategy, integrating nutritional approaches cautiously and based on individual profiles, may offer benefits, although no standard therapeutic guidelines currently exist.},

We analyzed GM composition and function in children before pLT, longitudinally post-pLT and in long-term survivors (LT-pLT) in order to assess the impact of disease severity, treatment and pLT on GM and delineate associations with graft and patient health. Fecal samples (FS) of 29 children (17f, age 2.6 [0.2-15.7] years) awaiting pLT were included with longitudinal follow-ups until 12M post-transplant in 18, and compared with 38 LT-pLT (21f, age 11 [2.7-17.7] years, 7.8 [1.0-17.0] years post-pLT) and 94 healthy controls (HC). Samples were analyzed using quantitative 16S rRNA gene analyses combined with shotgun metagenomics (subset of samples). Pre-pLT patients showed reduced alpha-diversities and altered GM composition compared with LT-pLT and HC, associated with disease severity and anti-pruritic treatment with Rifampicin. Dysbiosis increased after pLT and started to recover after 3M. Although bacterial concentrations, alpha diversity and gene richness increased post-pLT, levels remained below those of HC. Abundances of key functions, e.g. the capacity to synthesize butyrate, also remained reduced. Quantitative analyses revealed true extent of differences between patients and HC that were underestimated using relative abundance data. GM diversity and functional capacities correlated negatively with transaminase levels mid- and long-term after pLT. Random Forest analyses based on GM were able to predict hepatocellular damage at high accuracy (AUC: 0.89). We provide comprehensive, quantitative insights into GM composition and function before and after pLT. A link between GM alterations with (long-term) graft health was uncovered providing possible targets to modulate GM function in order to increase graft and patient health.},

The study focused on the balance of T-helper 17 (Th17) and regulatory T (Treg) cells, as well as the modulation of the JAK/STAT pathway. This study established a rat ARDS model using intranasal LPS instillation, administering interventions such as FMT, Treg cell depletion, and JAK inhibitors. Assessments included histopathological examination of lung and intestinal tissues, flow cytometry for Th17 and Treg cell proportions, qPCR and Western blot for gene and protein expression, ELISA for inflammatory cytokines, and correlation analysis using Spearman's method for cytokine-immune cell interactions. Results indicated that FMT and JAK inhibitors significantly reduce lung damage induced by LPS, reduced alveolar destruction and inflammation, restored Th17/Treg balance, and inhibited JAK/STAT pathway activity. Notably, FMT decreased pro-inflammatory cytokines (IL-2, IL-6, IL-8, IL-17A, IL-23, TGF-β1) and increased anti-inflammatory cytokines (IL-10, IL-35) in serum. Spearman correlation analysis indicated that FMT restored immune balance by modulating the interactions between cytokines and immune cells. In conclusion, FMT effectively alleviates lung and intestinal injury in LPS-induced ARDS rat models by modulating Th17/Treg balance and inhibiting JAK/STAT pathway activity, demonstrating promising therapeutic potential for ARDS treatment.},

abstract = {BACKGROUND: Anemia is a prevalent and challenging complication in patients with hematologic and solid malignancies, which stems from the direct effects of malignancy, treatment-induced toxicities, and systemic inflammation. It affects patients' survival, functional status, and quality of life profoundly. Recent literature has highlighted the emerging role of the gut microbiome in the pathogenesis of cancer-associated anemia. The gut microbiota, through its intricate interplay with iron metabolism, inflammatory pathways, and immune modulation, may either exacerbate or ameliorate anemia depending on its composition, and functional integrity. Dysbiosis, characterized by disruption in the gut microbial ecosystem, is very common in cancer patients. This microbial imbalance is implicated in anemia causation through diminished iron absorption, persistent low-grade inflammation, and suppression of erythropoiesis.

AIM: To consolidate current evidence regarding the interplay between gut microbiome and anemia in the setting of malignancies. It aims to provide a detailed exploration of the mechanistic links between dysbiosis and anemia, identifies unique challenges associated with various cancer types, and evaluates the efficacy of microbiome-focused therapies. Through this integrative approach, the review seeks to establish a foundation for innovative clinical strategies aimed at mitigating anemia and improving patient outcomes in oncology.

METHODS: A literature search was performed using multiple databases, including Google Scholar, PubMed, Scopus, and Web of Science, using a combination of keywords and Boolean operators to refine results. Keywords included "cancer-associated anemia", "gut microbiome", "intestinal microbiota", "iron metabolism", "gut dysbiosis", "short-chain fatty acids", "hematopoiesis", "probiotics", "prebiotics", and "fecal microbiota transplantation". Articles published in English between 2000 and December 2024 were included, with a focus on contemporary and relevant findings.

RESULTS: Therapeutic strategies aimed at restoration of gut microbial homeostasis, such as probiotics, prebiotics, dietary interventions, and fecal microbiota transplantation (FMT), can inhibit anemia-causing pathways by enhancing microbial diversity, suppressing detrimental flora, reducing systemic inflammation and optimizing nutrient absorption.

CONCLUSION: Gut dysbiosis causes anemia and impairs response to chemotherapy in cancer patients. Microbiome-centered interventions, such as probiotics, prebiotics, dietary modifications, and FMT, have shown efficacy in restoring microbial balance, reducing inflammation, and enhancing nutrient bioavailability. Emerging approaches, including engineered probiotics and bacteriophage therapies, are promising precision-based, customizable solutions for various microbiome compositions and imbalances. Future research should focus on integrating microbiome-targeted strategies with established anemia therapies.},

Loss of intestinal microbiome diversity is associated with cirrhosis progression, but the impact of microbiome-associated metabolites on liver disease remains largely undefined. We aimed to correlate fecal metabolite concentrations with the severity and progression of liver disease.

METHODS: In this cross-sectional study, fecal samples from patients hospitalized with liver disease were analyzed by shotgun metagenomic sequencing to determine microbiome compositions and targeted mass spectrometry to quantify SCFAs and BAs. Random survival forest and logistic regression models identified clinical, metagenomic, and metabolomic features associated with rehospitalization and survival.

RESULTS: This cross-sectional study included 24 chronic liver disease, 18 compensated cirrhosis, 225 decompensated cirrhosis and 40 acute-on-chronic liver failure patients and 27 control fecal donors. Microbiome sequencing and metabolite profiling correlated microbial diversity and SCFA and BA concentrations with liver disease severity. Butyrate and deoxycholic acid (DCA) were more important features than individual microbial species in random survival forest models predicting 30-day transplant-free survival, and low butyrate and DCA were associated with 30-day mortality (P < .0001). After controlling for model for end stage liver disease (MELD)-sodium score, disease stage, age and gender, low fecal concentrations of butyrate and DCA remained significant risk factors for death (Cox 1.38, P = .027). Bacterial species associated with butyrate and DCA concentrations included Bifidobacterium spp. and F. prausnitzii.

CONCLUSION: Mass spectrometry rapidly identifies patients with low fecal butyrate and DCA concentrations who are at increased risk of 30-day mortality. These findings set the stage for clinical trials of microbiome reconstitution with butyrate and DCA-producing bacterial species.},

abstract = {Primary immune thrombocytopenia (ITP) is an autoimmune disorder characterized by platelet destruction and impaired production, leading to bleeding risk. While immunosuppressive therapies are standard, many patients experience relapses or refractory disease, highlighting the need for novel approaches. Emerging evidence suggests the gut microbiota plays a role in immune regulation, yet its impact on ITP remains unclear. Dysbiosis has been linked to immune dysfunction in other autoimmune diseases, but whether it drives or results from immune dysregulation in ITP is debated. This review explores the gut-immune axis in ITP, focusing on microbiota-driven immune modulation, cytokine signaling, and platelet homeostasis. We assess microbiota-targeted interventions, including fecal microbiota transplantation (FMT), probiotics, and dietary modifications, while addressing key controversies and knowledge gaps. Advances in microbiome sequencing and artificial intelligence may facilitate personalized interventions. Standardizing microbiota-based diagnostics and validating their efficacy in clinical trials are crucial for their integration into ITP management. Bridging these gaps may lead to microbiota-driven strategies that enhance immune regulation and improve patient outcomes.},

abstract = {Since its discovery via metagenomics in 2008, human cosavirus (HCoSV) has been detected in the cerebrospinal fluid (CSF) and feces of humans with meningitis, acute flaccid paralysis (AFP), and acute gastroenteritis. To date, 34 HCoSV genotypes have been documented by the Picornaviridae study group. However, the documented genetic diversity of HCoSV in Nigeria is limited. Here we describe the genetic diversity of HCoSV in Nigeria using a metagenomics approach. Archived and anonymized fecal specimens from children (under 15 years old) diagnosed with non-polio AFP from five states in Nigeria were analyzed. Virus-like particles were purified from 55 pools (made from 254 samples) using the NetoVIR protocol. Pools were subjected to nucleic acid extraction and metagenomic sequencing. Reads were trimmed and assembled, and contigs classified as HCoSV were subjected to phylogenetic, pairwise identity, recombination analysis, and, when necessary, immuno-informatics and capsid structure prediction. Fifteen pools yielded 23 genomes of HCoSV. Phylogenetic and pairwise identity analysis showed that all belonged to four species (eleven, three, three, and six members of Cosavirus asiani, Cosavirus bepakis, Cosavirus depakis, and Cosavirus eaustrali, respectively) and seventeen genotypes. Ten genomes belong to seven (HCoSV-A3/A10, A15, A17, A19, A24, D3, and E1) previously assigned genotypes, while the remaining thirteen genomes belonged to ten newly proposed genotypes across the four HCoSV species, based on the near-complete VP1 region (VP1*) of the cosavirus genome. Our analysis suggests the existence of at least seven and eight Cosavirus bepakis and Cosavirus eaustrali genotypes, respectively (including those described here). We report the first near-complete genomes of Cosavirus bepakis and Cosavirus depakis from Nigeria, which contributes to the increasing knowledge of the diversity of HCoSV, raising the number of tentative genotypes from 34 to over 40. Our findings suggest that the genetic diversity of HCoSV might be broader than is currently documented, highlighting the need for enhanced surveillance.},

BEV infection significantly altered the microbiota composition, where the abundance of some beneficial bacteria, such as Lactobacillaceae and Lactobacillus, was markedly reduced. Mag effectively inhibited BEV infection in vivo. Upon BEV infection, Mag treatment reduced the α-diversity of the microbiota, with statistically significant differences on day 3 post-infection compared to the Mag-untreated group. More interestingly, Mag treatment significantly reversed the effect of BEV infection on the Lactobacillaceae and Lactobacillus abundance, indicating that Mag positively regulates beneficial bacteria. The fecal microbiota transplantation (FMT) experiment demonstrated that feces from Mag-treated mice significantly decreased the virus loads in the small intestine samples of BEV-infected mice. These findings demonstrate the interaction between BEV infection and the gut microbiota and highlight the important regulatory role of the gut microbiota in Mag's anti-BEV effects, opening up a new avenue for preventing and controlling BEV infection via targeted modulation of the gut microbiota.},

abstract = {Chronic kidney disease (CKD) has a high prevalence worldwide, with an increasing incidence. One of the mechanisms of CKD progression involves a disordered inter-organ relationship between the kidneys and the intestine, known as the kidney-gut axis. In CKD, two pathological gut conditions-disturbed gut microbiota composition called uremic dysbiosis and leaky gut-contribute to the progression of CKD. Dysbiosis is associated with the increased production of gut-derived uremic toxins, leaky gut, and chronic systemic inflammation, leading to worsening uremia, which in turn aggravates the gut condition. This vicious cycle should be a target of the therapeutic strategy against CKD. The modulation of uremic dysbiosis, including prebiotics, probiotics, and synbiotics, has been a typical treatment approach, although clinical evidence for their efficacy has been insufficient. Some non-antibiotic drugs have an impact on human gut bacteria that are believed to play a role in their clinical efficacy on kidney function. Nutrition therapies, including a low-protein diet, dietary fiber, a Mediterranean diet, and whole grains, positively influence gut microbiota composition and have been linked to a decreased risk of CKD. Novel strategies are currently being explored, involving the use of postbiotics, microbiome sequencing techniques, and fecal microbiota transplantation, although clinical application remains to be tested. Human trials investigating the above-mentioned interventions remain inconclusive due to several limitations, including dietary variability and genetic factors. Future research should focus on the development of more effective probiotics, prebiotics, and microbial metabolism-modifying drugs, not only for CKD but for other systemic diseases as well.},

abstract = {Lifestyle, diet, and genetics are established risk factors for developing colorectal cancer (CRC). In recent years, the role of the gut microbiota (GM) has been increasingly highlighted in several studies, suggesting an effect on both the disease's pathogenesis and the efficacy and tolerability of treatments. We conducted a search on Medline, aiming to identify published studies exploring the role of the GM in the development and treatment of CRC. Dysbiosis, an imbalance in GM, is common in CRC patients and is associated with precancerous lesions, aggressive tumors, and varied therapy outcomes. Restoring GM balance can reduce treatment complications and may improve prognosis. The review details how GM influences CRC through metabolite production, inflammation modulation, and immune response alteration. Diet significantly impacts GM composition, with processed meats and high-fat diets increasing CRC risk, while fiber-rich diets are protective. The role of the GM in CRC treatments like surgery, chemotherapy, radiotherapy, and immunotherapy is also explored, noting its influence on complications, chemoresistance, and treatment efficacy. Future strategies involving GM modulation through diet, probiotics, and fecal microbiota transplantation (FMT) show promise for CRC prevention and treatment, warranting further research.},

abstract = {Cancer cachexia is a multi-organ and multifactorial syndrome characterized by muscle wasting (with or without adipose tissue loss) and systemic inflammation in patients with advanced malignancies. Gut microbiota dysbiosis, particularly the depletion of short-chain fatty acid (SCFA)-producing bacteria, may contribute to the progression of cancer cachexia. Studies in both murine models and humans consistently associate cachexia with a decline in SCFA-producing gut microbiota commensals and an overgrowth of pro-inflammatory pathobionts. These microbial imbalances may lead to reduced levels of SCFAs and branched-chain amino acids (BCAAs) and alter the normal bile acid profile. BCAAs and the maintenance of a normal bile acid profile are associated with muscle synthesis and decreased breakdown. While SCFAs (acetate, propionate, and butyrate), contribute to intestinal barrier integrity and immune regulation. SCFA depletion may increase gut permeability, allowing bacterial endotoxins, such as lipopolysaccharide (LPS), to enter the bloodstream. This may lead to chronic inflammation, muscle catabolism, and impairment of anabolic pathways. Interventions targeting gut microbiota in preclinical models have mitigated inflammation and muscle loss. While clinical data are limited, it suggests an improvement in immune functions and better tolerance to anticancer therapies. Current evidence is predominantly derived from cross-sectional studies suggesting associations without causality. Thus, future longitudinal studies are needed to identify biomarkers and optimize personalized therapy.},

abstract = {The bilateral interaction between the brain and the gut has recently been on the spectrum of researchers' interests, including complex neural, endocrinological, and immunological signaling pathways. The first case reports and clinical studies have already reported that delivering microbes through fecal microbial transplantation (FMT) may alleviate symptoms of psychiatric disorders. Therefore, modifying the gut microbiota through FMT holds promise as a potential treatment for psychiatric diseases. This scoping review assessed studies from PubMed related to FMT in autism spectrum disorder and attention deficit hyperactivity disorder. The evaluation included nine clinical studies and case reports. The beneficial and persistent effect on the autism spectrum disorder (ASD) symptoms has been reported. Also, an increased microflora diversity and altered levels of neurometabolites in serum were identified, albeit with a tendency to return to baseline over time. The microbiome-gut-brain axis could provide new targets for preventing and treating psychiatric disorders. However, a recent large randomized clinical trial has shed light on the previously collected data and suggested a possible contribution of the placebo effect. This highlights the necessity of large randomized double-blind studies to reliably assess the effect of FMT in ASD.},
