Filter by:Ulcerative colitis (UC) is a chronic inflammatory bowel disease associated with recurrent mucosal inflammation. Clinically, the disease is characterized by bloody diarrhea, abdominal pain, and constitutional symptoms such as fever and weight loss. Treatment strategies vary based on disease activity and target various aspects of the inflammatory cascade. Options include: anti-inflammatory drugs (mesalamine), immunosuppressive or modulatory medications (corticosteroids, thiopurines, cyclosporine) and biologic agents (Anti-TNF). Disease severity can be wide ranging, and nearly 25% of UC patients are hospitalized for acute severe disease. Of these patients, 30% will undergo colectomy after the acute episode, a quarter of which will experience post-operative complications. Although there has been great progress in treatment of UC over the past decade, even with the anti-TNF agent infliximab, the one-year remission rate for patients not responding to conservative management is barely 20%. Furthermore, corticosteroids have significant long-term consequences and immune suppressive drugs such as 6-mercaptopurine, azathioprine and infliximab have been associated with serious adverse events including life-threatening infections and lymphomas. With growing evidence that the pathogenesis of UC is multi-factorial and involves a complex interaction of genetic and environmental factors, newer treatment modalities are being evaluated to target the mucosal immune response and mucosal inflammatory regulatory system. Hyperbaric oxygen offers a promising new treatment option since it targets both tissue hypoxia and inflammation. Recent small scales studies evaluating the impact of hyperbaric oxygen treatment in acute ulcerative colitis flares demonstrated improved outcomes. The mechanisms underlying the improvement are not known. In this study, we will treat ulcerative colitis flares with hyperbaric oxygen and measure changes in both markers of tissue hypoxia and inflammation. We hypothesize that hyperbaric oxygen will (a) improve outcomes, and (b) show reductions in markers of both tissue hypoxia and inflammation.
Ulcerative colitis (UC) is a chronic relapsing inflammatory bowel disease. UC pathogenesis remains poorly understood but involves an inappropriate immune response toward an unbalanced gut microbiota (called dysbiosis) in predisposed hosts. The purpose of this study is to determine the effect of the fecal microbiota transplantation on UC.
This trial has two sequentially enrolling parts with different objectives. The primary objectives of this trial are - to prove the concept of clinical activity of BI655130 (SPESOLIMAB) in patients with moderate-to-severely active ulcerative colitis who have failed previous biologic treatments and to identify efficacious and safe dose regimens in Part 1 (Phase II) - to confirm efficacy and safety of BI655130 (SPESOLIMAB) in patients with moderate-to-severely active ulcerative colitis who have failed previous biologic treatments in Part 2 (Phase III) - To provide, along with induction study 1368-0018 and the run-in cohort of 1368-0020, the target population to be evaluated in study 1368-0020.
This study will evaluate pharmacokinetics, pharmacodynamics and safety of etrolizumab in pediatric patients of 4 to <18 years of age with moderate to severe ulcerative colitis (UC) or with moderate to severe Crohn's disease (CD).
This is a prospective observational cohort study, over 52 weeks, evaluating the the use of faecal microbiota transplantation amongst patients with Inflammatory Bowel Disease and Microscopic Colitis
Aim of the work - To identify the prevalence of CMV infection in patients with steroid-refractory ulcerative colitis. - To assess the clinical and endoscopic conditions in these patients.
Ulcerative colitis (UC) belongs to the group of inflammatory bowel disease (IBD) and is characterized by a chronic relapsing disease course. As uncontrolled intestinal inflammation can lead to severe disease complications, treatment of UC has evolved from sole treatment of symptoms up to histological remission which is marked by the absence of histological inflammation. To correctly assess and quantify the degree of histological inflammation in IBD patients remains difficult. Digital holographic microscopy (DHM) is a new imaging technique belonging to quantitative phase contrast imaging. It is based on the detection of optical path-length delays in a stain-free manner, thereby providing a refractive index which directly correlates to tissue density. This study aims to evaluate the role of DHM for quantifying the degree of histological inflammation in endoscopically acquired biopsies of UC patients in a prospective clinical trial. From 28 UC patients, the investigators will obtain endoscopically acquired colonic biopsies. The investigators will assess the degree of inflammation in these biopsies using DHM and in addition to this an experienced histopathologist will determine the degree of inflammation in these biopsies using a histological scoring system (Nancy-Score = goldstandard). Finally, the investigators will directly correlate the results from DHM analysis to the histological analysis using the Nancy-Score.
This study evaluates the efficacy of prophylaxis with oral vancomycin for preventing recurrent Clostridium difficile Infection (CDI) in patients who have experienced at least one CDI episode in the last 180 days and are receiving antibiotics for a non CDI condition. Participants will be randomized to receive either placebo or oral vancomycin in addition to their prescribed antibiotic therapy.
Alterations in the intestinal microbiota have been associated to disease pathogenesis in ulcerative colitis. Refractory disease to standard medical therapy as corticosteroids often leads to an unfavourable course in patients suffering from this disorder. This study proposal aims at investigating changes in the intestinal microbiota that can predict a therapy refractory course of ulcerative colitis (UC) and may be used to identify high risk patients in an early phase of their disease.
The purpose of this observational study is to assess the safety and effectiveness of biosimilar Infliximab in patients with inflammatory bowel disease (IBD) in Saudi Arabia where no visits or intervention(s) additional to the daily practice will be performed.
