Active clinical trials for "Colitis"

The hypothesis of the study is that in ulcerative colitis repeated flares of inflammatory activity, as well as mechanisms involved in resolution of the inflammatory response, may contribute to accumulation of damage in the colon leading to functional disturbances and symptoms that affect patient's functioning. The primary objective is to determine whether ulcerative colitis induces permanent anatomical damage, by means of magnetic resonance imaging.

The purpose of this study is to describe the initial response to ustekinumab induction treatment for ulcerative colitis (UC) in Japan.

Background and rationale: In ulcerative colitis, treating beyond endoscopic healing has shown a reduction of relapse and hospitalization, pushing for histological remission in daily clinical practice.1 However, very little is known on how histological remission is associated with patient reported outcomes (PROMs).2,3 In recent years, several questionnaires have been developed to assess what really matters to patients: symptoms and the burden UC exerts on them.4 As PROMs are getting more and more attention during drug development programs and drug approval by international organizations, including FDA and EMA, the link between objective outcome measures (endoscopic, histological, biochemical) and PROMs should therefore be better characterized. Objectives and design: To investigate prospectively the association of patient reported outcomes (PROMs) and biochemical, endoscopic and histological outcome measures in patients with ulcerative colitis.

The purpose of the study is to develop a validated French version of the IBDQ in a cohort of patients suffering from Inflammatory bowel diseases, namely Crohn's disease and Ulcerative Colitis.

The purpose of this study is to evaluate the relation between sulphide detoxification and butyrate metabolism at the level of gene expression and enzyme activity in ulcerative colitis patients and healthy controls.

The aim of this study is to evaluate scintigraphic methods as objective factors for functional outcome in patients treated with ileal-pouch-anal anastomosis (IPAA). The gastrointestinal transit-time and the degree of evacuation are evaluated in relation to the functional outcome.

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).

This study aims to evaluate the impact of AbbVie Care 2.0 on adalimumab's compliance, patient reported outcomes and utilization of health resources over 12 months.

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.

A prospective, randomized trial to determine indigo carmine dye spraying and narrow band imaging (NBI) of colonic mucosa to detect dysplasia in ulcerative colitis (UC). Confocal laser microscopy may be beneficial in the further assessment of abnormalities identified by these methods.
