Filter by:Primary sclerosing cholangitis (PSC) is a progressive disease of the biliary tree, which represents one of the most frequent indications for orthotopic liver transplantation (OLTx) in developed countries. There are several lines of evidence that dietary gluten/gliadin displays chronic pro-inflammatory, LPS-like properties. Recent evidence demonstrated the protective effect of gluten- free diet (GFD) in autoimmune diseases like type 1 diabetes, irritable bowel syndrome, non-celiac gluten sensitivity and some neurological disorders. This study is intended to explore therapeutic effect of GFD on PSC and IBD in prospective self-controlled mono-centric intervention study. Hypothesis: Avoidance of gluten in diet will reduce progression, symptoms and intestinal inflammation in PSC and UC patients.
The goal of this placebo-controlled randomised multicenter trial is to evaluate the efficacy and safety of anaerobic prepared donor fecal microbiota transplantation (FMT) compared to autologous FMT in patient with ulcerative colitis. Participants will receive 4 treatments with frozen FMT via both upper and lower gastro-intestinal route (infusion via duodenal tube and enemas). Donors are selected based on microbiota profile.
Ulcerative colitis (UC) is one of the most common types of chronic and non-specific inflammatory bowel diseases (IBD). It is characterized by cytokine-induced continuous and diffuse inflammatory infiltrations into the rectum's mucosa and extends proximally to the colon. Patients with UC predominantly have bloody diarrhea, abdominal pain, fecal urgency, and tenesmus, which extremely alters their quality of life. Although the precise pathological mechanism of UC remains unclear, several studies have been outlined many factors that could involve in the pathogenesis of UC, including, but not limited to, initiation of the inflammatory response, disruption of oxidant/antioxidant status, dysregulation of the immune response, alteration of gut microbiota, and delaying epithelial barrier healing. Loss of intestinal barrier function and dysregulated immune response are the key events during colitis development
Chronic intestinal hypoxia and accompanying mucosal inflammation is a hallmark of ulcerative colitis (UC). Hyperbaric oxygen therapy (HBOT) involves breathing 100% oxygen under increased atmospheric pressure to increase tissue oxygenation. Two small prospective randomized controlled trials have demonstrated that the delivery of HBOT to UC patients hospitalized for acute moderate to severe flares results in improved remission rates and avoidance of in-hospital progression to biologics, small molecules, or colectomy. In this larger trial the study aims to confirm the treatment benefits of HBOT for hospitalized UC patients and study the immune-microbe mechanisms underpinning treatment response.
This study is only for the first in human phase 1a study designed to investigate the safety and tolerability of LIV001 in healthy participants. LIV001 will be investigated for the safety and efficacy in participants with Ulcerative Colitis (UC) in a phase 1b study.
Frequency of Inflammatory Bowel Diseases in children (IBD)-Crohn's disease (CD), Ulcerative colitis (UC) is constantly increasing. Pediatric-onset IBD represent a different nosological entity (from adult IBD) because of their major inflammatory activity, their significant anatomical extent and their stenotic and/or fistulizing character sometimes from diagnosis. Intestinal lesions are due to dysregulation of the intestinal immune system but the cause is unknown. The investigators hypothesize that extranuclear DNA participates in the amplification of the inflammatory response at the intestinal and blood levels during pediatric IBD through the cGAS-STING pathway. The investigators will analyse blood and fecal samples, and colonic biopsies issued from ill children and control participants on age of 6 to 17 years. The investigators think that this study will provide a better understanding of the mechanisms involved in pediatric IBD, assess the place of the cGAS-STING pathway, identify potential biomarkers of pediatric IBD and new potential therapeutic targets based in particular on the inhibition of the cGAS-STING pathway.
Although the incidence of inflammatory bowel disease is stable in North American and European countries, the incidence of inflammatory bowel disease is increasing in newly industrialized countries, especially in China. The treatment drugs for ulcerative colitis include 5-aminosalicylic acid (5-ASA), glucocorticoids, immunosuppressants, and biological agents. The aim of this exploratory Clinical Trial is to evaluate the safety and efficacy of sacral nerve stimulation in patients with ulcerative colitis.
Patients presenting with severe symptoms of ulcerative colitis (UC) require hospital admission for urgent assessment and therapy. Endoscopic examination of the rectum and/or distal colon is often performed to assess severity and obtain tissue for histopathologic evaluation, but this is often extended to full colonoscopy to assess the extent of bowel involvement. Full colonoscopy is hazardous in this setting
The goal of this trial is to create personalized treatments for each patient admitted to the hospital with acute severe ulcerative colitis (ASUC). The study will test the feasibility and acceptability of these treatment strategies among patients and physicians so that the study team can later do a larger trial to test whether the medication treatment pathways help patients avoid colectomy while ensuring patient's are safe.
This is a dose ranging exploratory phase 1 pilot study to assess engraftment, safety, and efficacy of CP101, an oral microbiome therapeutic, in participants with active mild-to-moderate Ulcerative colitis. A total of 30 patients who meet eligibility criteria will be randomized 1:1 to either a short or extended induction dosing with CP101. An assessment of the microbiome will occur at baseline, Day 6, Week 4, Week 8, Week 12, Week 16, and Week 24.
