Background: Chronic constipation, a prevalent gastrointestinal disorder with limited treatment efficacy in refractory cases, has prompted exploration of fecal microbiota transplantation (FMT) as a novel therapeutic strategy. This systematic review and meta-analysis evaluate the efficacy, safety, and gut microbial dynamics of FMT in adults with chronic constipation.
Methods: We systematically searched PubMed, Embase, Web of Science, and Cochrane Library up to January 2025, identifying 1,072 records. Nine studies ( = 245 patients) met inclusion criteria for qualitative synthesis, with eight contributing to meta-analysis. Outcomes included constipation remission and improvement, stool metrics, quality of life, and microbiota changes. Random-effects models analyzed pooled remission rates, mean differences (MDs), and heterogeneity (I statistics).
Results: Fecal microbiota transplantation achieved a 50.7% pooled remission rate (95% CI: 38.7%-62.7%) and 64.8% improvement rate (95% CI: 51.4%-76.3%). Significant improvements were observed in stool consistency (MD = 1.32, 95% CI: 1.05-1.35), quality of life (GIQLI MD = 32.19, 95% CI: 17.15-47.23), and symptom severity (Wexner MD = -4.83, 95% CI: -7.15-2.51). Post-FMT microbiota analyses revealed enrichment of beneficial taxa (Bifidobacterium, Prevotella; Firmicutesacteroidetes) and suppression of pro-inflammatory Enterobacteriaceae. Transient gastrointestinal adverse events (e.g., bloating: 17.3%) resolved spontaneously, with no severe complications reported.
Conclusion: Fecal microbiota transplantation demonstrates clinically meaningful symptom relief and gut microbiota remodeling in chronic constipation, supported by favorable short-term safety. While heterogeneity in protocols and limited RCT data warrant caution, these findings advocate standardized FMT frameworks and confirmatory trials to optimize therapeutics for refractory constipation.

Background: A plant-focused, healthy dietary pattern, such as the Mediterranean diet enriched with dietary fiber, polyphenols, and polyunsaturated fats, is well known to positively influence the gut microbiota. Conversely, a processed diet high in saturated fats and sugars negatively impacts gut diversity, potentially leading to weight gain, insulin resistance, and chronic, low-grade inflammation. Despite this understanding, the mechanisms by which the Mediterranean diet impacts the gut microbiota and its associated health benefits remain unclear.

Acute graft-versus-host disease (GVHDa) is one of the leading causes of morbidity and mortality after allogeneic hematopoietic stem cell transplant (HSCT) patients. While the first-line consensus treatment has been based on systemic corticosteroid therapy for many years, ruxolitinib has recently been approved and has become the standard second-line treatment. Nevertheless, the effectiveness of ruxolitinib remains limited to 40 % of cortico-resistant patients, raising the crucial question of selecting a third-line treatment.

Background: Dietary fiber supports metabolic health via microbial fermentation, producing short-chain fatty acids (SCFAs). However, metabolic responses to fiber vary between individuals, potentially due to differences in gut microbiota composition. The Prevotella-to-Bacteroides (P/B) ratio has emerged as a potential biomarker for fiber responsiveness.

Volvaria volvacea polysaccharides (VVP) possess diverse bioactivities with promising applications in biomedicine and functional foods. This study investigated the metabolic fate of VVP in human gut microbiota and uncovered the pivotal role of Bacteroides thetaiotaomicron using in vitro fecal fermentation models. VVP selectively promoted B.
