Active clinical trials for "Colitis, Ulcerative"

The primary objective is to obtain stool samples from subjects diagnosed with , and displaying signs and/or symptoms of IBD and/or IBS will be evaluated in this study. Eligible subjects require a diagnostic colonoscopy with possible biopsy and clinical evaluation.

Establishing that mucosal healing (MH) has occurred after therapy is an important treatment goal, and the gold standard is endoscopic evaluation. In UC it is unclear if clinical parameters are adequate. The pediatric ulcerative colitis activity index (PUCAI) has demonstrated good correlations for clinical remission and disease severity, but its role for establishing mucosal healing after therapy has not been validated . The ability to predict mucosal healing may be different for patients in long term remission compared to assessment after obtaining clinical remission. No previous study has prospectively validated the use of PUCAI as a proxy for MH specifically during clinical remission after therapy.

The purpose of this study is to establish the incidence of sub-optimal response to anti-TNF therapy in UC and CD participants.

A study to describe the one-year persistence in participants treated by Flixabi (infliximab) or Imraldi (Adalimumab) as prescribed by the physician for each of the 5 following indications: Rheumatoid Arthritis (RA), Ankylosing Spondylitis (AS), Psoriatic Arthritis (PsA), Crohn's Disease (CD) [adults and children] and Ulcerative Colitis (UC) [adults for both treatments and children only for Flixabi].

Primary sclerosing cholangitis (PSC) occurs in approximately 10 % of patients with ulcerative colitis (UC), but the outcome of reconstructive surgery is not clear. The purpose of this study was to determine the functional outcome after surgery, frequency of pouchitis, complications and failure-rate in UC-PSC patients compared to patients with UC alone. Both ileal pouch-anal anastomosis (IPAA) and ileo-rectal anastomosis (IRA) were studied.

The hypothesis underlying this study is that failure to recognise the role of lactose intolerance among patients with ulcerative colitis has led to inappropriate dietary advice and treatment with drugs that contain lactose as a filler. These failures exacerbate symptoms and lead to the unnecessary use of immune suppressant drugs. There is disagreement amongst researchers regarding the amount of lactose needed to cause symptoms in those who are lactose intolerance. The general consensus is that the amount of lactose in a glass of milk (12 grams) is enough to cause mild symptoms in most patients who are lactose intolerant (1). However, there have been a number of studies and case studies that argue that much lower amounts can cause symptoms (2, 3, 4, 5). This could be as little as 0.02 grams (6). Ulcerative colitis is a chronic relapsing inflammatory disease of the colon and rectum, characterised by recurrent episodes of abdominal pain and profuse diarrhoea. The prevalence of lactose intolerance in patients with ulcerative colitis is not greater than in the general population, but there is no evidence as to whether these patients are more sensitive to lactose. This study will identify the threshold at which symptoms of lactose intolerance develop in those who have both lactose intolerance and ulcerative colitis, to provide appropriate advice and treatment in the management of patients with these conditions.

The purpose of this study is to look at the importance of L-Arginine in the digestive tract. L-Arginine is an amino acid and is important in making proteins within the cell. The evaluation of colon tissue, blood, urine, diet, health history, and symptoms will help us learn more about L-Arginine and ulcerative colitis. The investigators believe these studies will provide new insights into the treatment for Inflammatory Bowel Disease (ulcerative colitis) and nutritional needs. The investigators plan to enroll 200 participants in this study over the next two years.

This is a study of the electronical dosing tool MedicPen and it's qualities with regards to user friendliness and medication compliance.

Acute severe ulcerative colitis [ASUC] patients have high risk of no response to medical treatments and might miss the best timing for surgery when waiting for the medical response. Thus, we investigated whether biomarkers which could early predict the surgery risk of patients with ASUC on admission.

Helicobacter pylori (H. pylori) infection is one of the most common infectious diseases in humans.
