Filter by:Microscopic colitis is a common cause of watery diarrhea, particularly in the elderly. Although the incidence is comparable to ulcerative colitis and Crohn's disease, the etiology is unknown. Understanding the etiology of microscopic colitis is an important step in developing logical interventions to decrease the burden from microscopic colitis. This research could provide critical insights into the etiology of this poorly studied condition.
The purpose of this research study is to improve the understanding of irritable bowel syndrome (IBS) and its underlying cause. The investigators will use magnetic resonance imaging (MRI) to observe differences in the brain between people diagnosed with IBS compared to healthy controls and people with ulcerative colitis, a disease group that has already been characterized. By doing this correlative and comparative study, the investigators hope to gain knowledge on IBS in order to keep the field moving in the right direction and becoming one step closer to discovering effective treatments.
Colitis from reactivation of established cytomegalovirus (CMV) colonization can complicate the clinical course in patients with an acute flare of ulcerative colitis (UC). Accurate and timely detection of active CMV infection or disease with appropriate anti-viral therapy may reduce complications associated with acute UC flare. Limited information is available on the presence of colonic CMV infection in patients with quiescent ulcerative colitis. Prospective studies on factors associated with reactivation of CMV infection during active UC flare and its impact on disease progression are lacking. The hypothesis of this study are as follows: 1) CMV infection is prevalent in patients with ulcerative colitis irrespective of disease severity; 2) The degree of immunosuppression directly impacts CMV infection status in patients with ulcerative colitis
The purpose of this study is to assess the long-term safety of vedolizumab versus other biologic agents in participants with Ulcerative Colitis (UC) or Crohn's Disease (CD).
The role of steroids in the treatment of severe ulcerative colitis (UC) exacerbation is well established and recommended by professional societies. Similarly, 5-aminosalycilates (5-ASA) agents in the form of mesalamine/mesalzine are well established proven therapy in mild-moderate UC, and the combination of oral 5-ASA with topical (per-rectal enema) 5-ASA was shown to be superior to oral 5ASA alone in patients with mild moderate UC. Thus, in most cases, when a patient with UC experiences a flare while taking 5-ASA therapy, treatment is usually optimized by maximizing the oral dose to 4gr/day and adding topical therapy until the flare is controlled. If this is unhelpful, or if the flare is severe to begin with, corticosteroids are usually prescribed. However, there are very scarce data comparing steroids versus 5-ASA in the treatment of severe UC exacerbation. The aim of this study is to compare the efficacy of steroids alone vs. combination of steroids + 5-ASA in the treatment of moderate-severe UC exacerbation.
The purpose of this study is to determine the safety and tolerability of administration of multiple ascending doses of KHK4083 and to select the highest dose tolerated by subjects with moderately active Ulcerative Colitis (UC) followed by a Long-term Extension Therapy (LTE) phase for eligible subjects with a clinical response.
This multi-centre open label study will involve a minimum of 120 patients in 2 cohorts: 60 patients with 'early UC' defined as disease duration < 4 years and no other treatments than aminosalicylates and/or corticosteroids and 60 patients with 'late UC' defined as active disease despite treatment with immunosuppressives (IS) and/or anti-TNF. Patients wih intolerance to IS AND anti-TNF will also be allowed in the latter group. Participants will be treated with 12 months of open label vedolizumab and undergo monitoring of endoscopic, histological and clinical disease parameters. No randomization or blinding will be performed but the study management will make sure recruitment in either study group is comparable for number and profile of patients (extent of disease and on/off corticosteroids).
The purpose of this study is to determine whether fecal calprotectin, fecal immunochemical test, and Rome III criteria for irritable bowel syndrome (IBS) can predict mucosal healing in patients with quiescent ulcerative colitis (UC).
Monocentric, prospective interventional study to assess the degree of disease activity with a multispectral optoacoustic tomography (MSOT) handheld scanner in patients with Crohn's disease or ulcerative colitis.
