Ulcerative Colitis Relapse Prevention by Prebiotics
Ulcerative colitis (UC) is a relapsing chronic intestinal inflammation with no existing cure, that affects over 300 per 100.000 Canadians, the highest prevalence in the world. The standard drug therapies are expensive and potentially toxic, and mostly directed against the chronic inflammatory process. UC is the result of a dysbiosis between disease-inducing and protective intestinal bacteria in a genetically susceptible host. Non-digestible dietary carbohydrates (NDC) stimulate the growth of protective endogenous intestinal bacteria which ferment them into short-chain fatty acids (SCFA), some of the latter with natural anti-inflammatory...
Ulcerative Colitis - Vedolizumab- With/Without Prior Exposure to Anti-TNF（Tumor Necrosis Factor）Therapy
A case-control study to evaluate the immunoinflammatory effect of prior exposure to anti-TNF therapy in patients with ulcerative colitis starting vedolizumab therapy
Understanding Abdominal Pain in IBD and IBS
Abdominal pain is a central symptom of Inflammatory Bowel Disease (IBD) and Irritable Bowel Syndrome (IBS). IBD is an autoimmune disease characterized by inflammation of the gastrointestinal tract. IBS does not have clear biomarkers and is diagnosed based on symptom reports. The aim of this study is to explore biopsychosocial factors which may perpetuate and/or increase the severity of pain in these conditions. The main focus will be on the role of top-down brain processes in the experience of abdominal pain.
Use of a Novel Diet (UC DIET) for Treatment of Mild to Moderate Active Pediatric Ulcerative Colitis
The goal of the study is to evaluate strategies that target the microbiota for the treatment of Ulcerative Colitis , This study will involve a novel diet that the investigators developed , based on the hypothesis that UC involves dysbiosis , underutilzation of certain metabolic pathways and use of pathways that increase risk of inflammation . The investigators have postulated that manipulation of colonic bacterial metabolism with this diet will induce remission in UC without involving additional immune suppression.
USTekinumab in Fistulising Perianal Crohn's Disease (USTAP)
Phase IV Trial design : Multicentre, randomized, double-blind, placebo-controlled study Population : Moderate to severe Crohn's disease with at least one active perianal fistula track Investigational treatment : Group 1: Ustekinumab (UST) IntraVenous (IV) induction (6mg/kg) followed by UST SubCutaneous (SC) 90mg every 8 weeks. Group 2: Placebo IV followed by Placebo SC The trial duration for each patient will be 48 weeks. Trial objective : To evaluate the efficacy and safety of ustekinumab in fistulizing perianal Crohn's disease. Number of patients : A total of 146 patients will be included in 20 sites in France ...
Value of Pharmacokinetic Assays in the Prediction of Induction and Maintenance Therapeutic Response in Crohn's Disease
Vedolizumab (VDZ) is a monoclonal antibody which has shown its efficacy in Crohn's disease by inducing and maintaining clinical response/remission. The French marketing authorization was obtained for Crohn's disease in patients in failure with anti-TNF (Tumor Necrosis Factor) agents. For Crohn's disease patients treated with vedolizumab, a strong association between vedolizumab serum levels and clinical response to induction and maintenance was demonstrated by anterior studies. It could be of paramount interest to early identify Crohn's Disease patients under vedolizumab who will be responders to vedolizumab induction and to...
Value of Pharmacokinetic Assays in the Prediction of Therapeutic Response in Ulcerative Colitis
Vedolizumab (VDZ) is a monoclonal antibody that binds to the heterodimer α4β7 integrin and which has shown its efficacy in Ulcerative Colitis (UC) by inducing and maintaining clinical response/remission. The French marketing authorization was obtained for Ulcerative Colitis in patients in failure with anti-Tumor Necrosis Factor (anti-TNF) agents. In the pivotal study, correlation between drug levels and clinical response during induction and maintenance therapy were reported. Moreover, in 3.7% of cases, anti-vedolizumab antibodies were reported during the time-course and 1% had samples that were persistently positive. Up to now, data on the...
Vegetarian Diet in Ulcerative Colitis
To determine whether a lacto-ovo vegetarian diet is effective in improving gastrointestinal symptoms, quality-of-life, intestinal inflammation and gut microbiota composition in mild-to-moderate UC compared to a standard omnivorous diet.
Washed Microbiota Transplantation Improves Nutritional Status of Patients With Crohn's Disease
Patients with Crohns' disease (CD) are always complicated with malnutrition. Exclusive enteral nutrition (EEN) is an effective treatment to improve nutritional status and induce remission in patients with CD however a reduction in microbiota diversity was the most frequently reported effect of EEN. There was a raised critical question that whether EEN combining microbiota transplantation can bring much more benefits to those CD patients with malnutrition. Fecal microbiota transplantation (FMT) is an effective way of remodeling microbiota. The improved methodology of FMT in our group since 2014 was different from the traditional manual ...
