An increasing use of immunomodulatory drugs has led to a corresponding increase in treatment-related pathologies such as inflammatory bowel disease. Here, we present a case of ulcerative colitis due to Obinutuzumab, an antiCD20 monoclonal approved for the treatment of Non-Hodgkin lymphomas.

Ulcerative colitis, a chronic inflammatory condition of the colon, requires precise and targeted treatment, and polysaccharides, with their pH responsiveness and biodegradability, offer an innovative approach for colon-specific drug delivery. This study aims to develop a highly precise drug delivery system with enhanced therapeutic and targeting efficiency for ulcerative colitis, focusing on the preparation, optimisation, and evaluation of dual cross-linked mesalamine-loaded sericin-pectin (DSPs) micro-beads. These beads utilise the pH-responsive and microflora biodegradability properties of polysaccharides for targeted colon delivery, employing the Response Surface Methodology.

Background: Ulcerative colitis (UC), an inflammatory disease characterized by intestinal barrier dysfunction, poses significant challenges because of the toxicity and adverse effects commonly associated with conventional therapies. Safer and more efficacious treatment strategies are needed.
Purpose: The purpose of this study was to treat UC with Folium Artemisiae Argyi exosome-like nanovesicles (FAELNs) and to explore its related mechanism to provide a safer and more effective means for the treatment of ulcerative colitis.

Background And Aims: Patients with very early-onset inflammatory bowel disease (VEO-IBD), with an age of onset < 6 years, can present with severe manifestations and may require biologic therapy. Infliximab and adalimumab are approved for induction and maintenance in pediatric IBD patients but are licensed only above the age of 6 years. Effectiveness and safety data on adalimumab in this patient population are lacking.

Crohn's disease (CD) and ulcerative colitis (UC) are chronic relapsing inflammatory bowel disorders (IBD), the pathogenesis of which is uncertain but includes genetic susceptibility factors, immune-mediated tissue injury and environmental influences, most of which appear to act via the gut microbiome. We hypothesized that host-microbe alterations could be used to prognostically stratify patients experiencing relapses up to four years after endoscopy. We therefore examined multiple omics data, including published and new datasets, generated from paired inflamed and non-inflamed mucosal biopsies from 142 patients with IBD (54 CD; 88 UC) and from 34 control (non-diseased) biopsies.

This study investigated the protective effects of the dietary polyphenol vanillic acid (VA) on dextran sulfate sodium-induced acute ulcerative colitis (UC) in mice, focusing on its impact on the gut microbiota and inflammatory responses. VA was supplemented following dextran sulfate sodium administration, and key indicators, including body weight, disease activity index, colon length, spleen index, and inflammatory markers, were assessed. VA supplementation significantly alleviated UC symptoms, preserved intestinal barrier integrity, and reduced pro-inflammatory cytokine levels.
