Approximately 50% of the patients with ulcerative colitis (UC) are primarily nonresponsive to anti-tumor necrosis factor (TNF) therapy or lose their responsiveness over time. The gut microbiota plays an important role in resistance UC anti-TNF therapy; however, underlying mechanism remains unknown. Here, it is found that transplantation fecal from alters diversity dextran sulfate sodium-induced mice and may affect therapeutic infliximab. Furthermore, abundances Romboutsia Fusobacterium increase tissues who do not respond therapy. Differentially abundant metabolites mainly enriched nicotinate nicotinamide metabolism NCM460 cells after nucleatum infection. Mechanistically, F. promotes adenine dinucleotide (NAD+) salvage pathway by upregulating NAMPT expression, which subsequently leads activation p38 mitogen-activated protein kinase (MAPK) signaling secretion inflammatory factors, ultimately inhibiting response drugs. These findings demonstrate can influence highlight potential targeting its associated pathways for preventing treating drug UC.

Gut microbiota imbalances have a significant role in the pathogenesis of Inflammatory Bowel Disease (IBD) and Non-Alcoholic Fatty Liver (NAFLD). Herein, we compared gut microbial composition patients diagnosed with either IBD or NAFLD combination both. Seventy-four participants were stratified into four groups: IBD-NAFLD, IBD-only, NAFLD-only patients, healthy controls (CTRLs). The 16S rRNA was sequenced by Next-Generation Sequencing. Bioinformatics statistical analysis performed. Bacterial α-diversity showed lower value when IBD-only group to other groups particularly against IBD-NAFLD group. β-diversity also difference among groups. higher Bacteroidetes/Firmicutes ratio found only comparing CTRLs. Comparing group, decrease differential abundance Subdoligranulum, Parabacteroides, Fusicatenibacter found. groups, there Alistipes, Odoribacter, Sutterella, Lachnospira.

Vedolizumab (VDZ) is a humanized, gut-selective biologic used in the treatment of ulcerative colitis (UC). However, data on predictive factors for response are limited. This study aims to develop nomogram predict VDZ responsiveness UC. We retrospectively collected clinical from patients with moderate-to-severe active UC who received induction therapy at Chongqing General Hospital December 2020 March 2024. Full-slide images colon biopsies prior were analyzed quantify mean mucosal eosinophil density (MMED). Based 14-week post-treatment, categorized into responsive and non-responsive groups. In total, 84 analyzed, 58 responding 26 not responding. Significant differences observed pathological indices, MMED showing statistically significant difference between groups (p < 0.001). Serum biomarkers, including C-reactive protein (CRP), also showed (P = 0.015), as did CRP/albumin (CRP/ALB) ratio 0.018). Additionally, UCEIS scores differed significantly 0.025). Independent risk identified through multivariate logistic regression analysis establish model, presented nomogram. The area under curve (AUC) combined CRP model was 0.867 (95% CI: 0.781–0.953, p 0.001), indicating high accuracy predicting efficacy.

Addressing the escalating global burdens of inflammatory bowel disease and antimicrobial resistance demanded innovative food-based approaches to fortify gut health suppress pathogens. We introduced a novel edible probiotic, Enterococcus faecalis HY0110, isolated from marine Thunnus thynnus. Through comprehensive in vitro, vivo, metabolomic analyses, we demonstrated its superior antibacterial effects compared Lactobacillus rhamnosus GG, along with significantly enhanced antioxidant free-radical scavenging capacities. Notably, elevated acetic acid production strongly correlated efficacy (R ≥ 0.999). HY0110 also exerted antiproliferative on HT-29 colorectal cancer cells by attenuating β-catenin BCL-2 expression while upregulating pro-apoptotic markers P62 c-PARP. In DSS-induced colitis model, alleviated inflammation, restored microbial homeostasis, deterministic processes community assembly dynamics. Furthermore, fermenting Periplaneta americana powder triggered extensive metabolic remodeling, notably 668.73-fold rise astragaloside A, plus increases L-Leucyl-L-Alanine, S-lactoylglutathione, 16,16-dimethyl prostaglandin A1. These shifts diminished harmful components amplified essential amino acids peptides bolster immune modulation, redox balance, anti-inflammatory responses. This work established transformative paradigm for utilizing probiotics entomological substrates functional foods, presenting strategic pathways precision nutrition management.

Bisphenol A (BPA), a widespread environmental contaminant used in plastics and resins, poses significant health risks due to its endocrine-disrupting properties potential for inducing intestinal toxicity. This study explored the toxicological effects of BPA on small intestine rats, focusing duodenum, jejunum, ileum. Histopathological evaluation revealed that duodenum experienced most severe structural damage, including villous atrophy, epithelial shedding, mitochondrial degeneration. exposure disrupted oxidative stress homeostasis by reducing superoxide dismutase activity increasing malondialdehyde levels, along with upregulating antioxidant-related genes like GPX2 HO-1 upregulated, indicating lipid peroxidation damage. Inflammatory markers such as IL-1 NFκB were significantly highlighting an active inflammatory response cell apoptosis. also altered metabolism, increased expression lipogenic SREBP-1c FAS, metabolic dysregulation. Fecal microbiota analysis reduced α-diversity, enrichment pathogenic taxa Escherichia-Shigella, depletion beneficial genera Lachnospiraceae NK4A136 group, exacerbating gut inflammation barrier dysfunction. These findings suggest BPA-induced damage is driven stress, inflammation, dysbiosis, jejunum being more vulnerable segments.
