We investigated the actions of probiotics, Streptococcus faecalis 129 BIO 3B (SF3B), in a trinitrobenzenesulfonic acid- (TNBS-) induced colitis model in rats. After TNBS was administered into the colons of rats for induction of colitis, the rats were divided into two groups: one group was given a control diet and the other group was given a diet containing SF3B for 14 days. There were no apparent differences in body weight, diarrhea period, macroscopic colitis score, and colonic weight/length ratio between the control group and SF3B group, suggesting that induction of colitis was not prevented by SF3B. Next, we investigated whether SF3B-containing diet intake affects the restoration of enteric neurotransmissions being damaged during induction of colitis by TNBS using isolated colonic preparations. Recovery of the nitrergic component was greater in the SF3B group than in the control group. A compensatory appearance of nontachykininergic and noncholinergic excitatory components was less in the SF3B group than in the control group. In conclusion, the present study suggests that SF3B-containing diet intake can partially prevent disruptions of enteric neurotransmissions induced after onset of TNBS-induced colitis, suggesting that SF3B has therapeutic potential.

Background: The possible nonlinear association with therapeutic outcomes in ulcerative colitis may contribute to the inconclusive cutoff values of fecal calprotectin (FC). We aimed to explore the nonlinear association between FC levels and long-term therapeutic outcomes in patients with ulcerative colitis and establish a clinically applicable FC index.
Methods: We included patients treated with vedolizumab or adalimumab from the VARSITY (n=661) and GEMINI 1 (n=620) studies as discovery and validation cohorts, respectively.

Introduction: Iron overload disrupts gut microbiota and induces ferroptosis, contributing to colitis. However, whether gut microbiota directly drives iron overload-induced colitis and its underlying mechanism remain unclear.
Objectives: The study aimed to explore whether gut microbiota can directly regulate iron overload-induced colitis and its underling mechanism.

Background/aims: Upadacitinib is a novel selective Janus kinase inhibitor approved for use in ulcerative colitis. Clinical trials had rigorous criteria and excluded many patient subgroups. Given limited real-world effectiveness data, we examined outcomes of patients treated with upadacitinib for ulcerative colitis in a real-world population.

Background: Interleukin-23 inhibition is effective in treating ulcerative colitis. Guselkumab is a dual-acting, human IgG1, interleukin-23p19 subunit inhibitor that potently neutralises interleukin-23 and can bind to CD64. We aimed to evaluate the efficacy and safety of guselkumab as induction and maintenance therapy in patients with ulcerative colitis.

Background And Aims: Existing findings on outcomes of anti-tumor-necrosis-factor (TNF) therapy in patients with inflammatory bowel diseases (IBD) are largely based on retrospective studies. We aimed to investigate real-world outcomes of anti-TNF therapy and predictors thereof in a prospective IBD cohort.
Methods: In a Danish multicenter cohort of adult bio-naïve patients with IBD treated with anti-TNF, we assessed clinical response and remission to induction therapy using clinical disease activity scoring indices at week 14.
