Active clinical trials for "Colitis"

This pilot prospective study will investigate the role of microbiota and known enteropathogens in Acute Severe Ulcerative Colitis (ASUC). Investigators will compare a group of patients hospitalized for an ASUC with patients experiencing a Non-Severe Ulcerative Colitis (NSUC) flare by investigating microbiome, metabolome and transcriptome and integrating this data through a multi-omic framework. This systems biology approach aims at enhance our understanding of this severe event, define diagnosis and prognosis biomarkers to improve medical therapy and avoid colectomy and/or death.

Colonic diverticula are common in Western countries, affecting up to 60% of subjects over 70 years of age. In about 80% of patients, colonic diverticula remain asymptomatic (diverticulosis), while approximately 20% of patients may develop abdominal symptoms (symptomatic uncomplicated diverticular disease, SUDD) and, eventually, complications such as bouts of diverticulitis or bleeding. A small proportion of patients with colonic diverticulosis may develop segmental colitis associated with diverticulosis (SCAD). SCAD is separate clinical disease with specific macroscopic (erythema, friability and ulcerations) and microscopic features characterized by chronic, mucosal inflammation involving the inter-diverticular mucosa (usually sigmoid colon) sparing the proximal colon and rectum colon. The most common symptoms of SCAD are rectal bleeding, diarrhoea and abdominal pain. To achieve SCAD diagnosis a correct biopsies sampling is mandatory. It is necessary to take biopsies on the borders of the diverticula and in the apparently normal adjacent mucosa as well as biopsies in both the colon proximal to the diverticular area and the rectum in order to exclude chronic inflammatory bowel disease. The spectrum of histological lesions associated with SCAD is variable, including mild non-specific inflammation and inflammatory bowel disease (IBD)-like changes. Currently, data regarding prevalence of SCAD are scarce. It has been estimated that in patients with diverticulosis, SCAD prevalence ranged from 0.3-1.3%. The aim of the present study is to assess prospectively the prevalence of segmental colitis associated with colon diverticulosis (SCAD), in consecutive patients with colic diverticulosis, in a tertiary university centre.

Mucosal inflammation in patients with UC is the result of immunosuppression disturbance because decreasing number of regulatory T ly and activation IL 17

The purpose of this study is to describe gastrointestinal (GI) motility in patients suffering from severe Ulcerative Colitis (UC) and to compare these results with similar results obtained in remission. The study is done with the use of Motilis 3D-Transit system which consists of a small electronic capsule ingested and detected by a receiver carried by the patient. Position and orientation of the capsule are interpreted by dedicated computer software and transit times, progression velocity and contraction frequencies can be revealed. The study is mainly descriptive and is designed to test and evaluate the usefulness of the Motilis 3D Transit system in UC patients and to tell investigators more about GI motility during and after severe inflammation. Motilis 3D-Transit system gives investigators a unique chance to study the gastrointestinal canal as a whole during and after severe illness. The investigators expect to include 20 patients suffering from severe UC admitted to Hospital with the purpose of getting medical treatment. The investigators do not expect any drop out, but in case of drop out a new patient will be included.
