NCT ID: NCT02822352 Completed - Ulcerative Colitis Clinical Trials

RCT: HDWL vs Virtual Chromoendoscopy in the Detection of Intraepithelial Neoplasia in Longstanding Colitis

VIRTUOSO
Start date: August 2016
Phase: N/A
Study type: Interventional

Colitis is inflammation of the large bowel and it is often caused by conditions known as ulcerative colitis and Crohn's disease. In these conditions, the body has an exaggerated inflammatory response against the bowel - the body attacks the bowel. Patients who have had colitis affecting most of the large bowel for more than 8 years are at increased risk of cancer of the large bowel. In view of this, many national gastroenterology organisations have recommended that such patients have regular colonoscopies to detect pre-cancerous areas and even early cancer in the large bowel. Early detection of such areas, will lead to early treatment thereby reducing the risk of developing significant large bowel cancer. These regular colonoscopies are known as surveillance colonoscopies. Official international guidelines for surveillance in patients with ulcerative and Crohn's colitis advise to take 4 random samples of large bowel tissue (biopsies) every 10 centimeters and of any suspicious areas. Recent studies have shown that spraying dye such as indigo carmine (a type of food dye) helps highlight abnormal areas that could harbor pre-cancerous cells. This technique is time-consuming, and tedious. There are no set standards of what is considered a satisfactorily completed dye spray colonoscopy. The uptake of this technique in the UK has not been uniform. Therefore virtual chromoendoscopy has been studied as an alternative method to improve the detection of pre-cancerous tissue in patients with longstanding colitis.

Manipulating the Microbiome in IBD by Antibiotics and FMT

FMT
Start date: January 2014
Phase: N/A
Study type: Interventional

the etiology of Inflammatory Bowel Diseases (IBD) is closely associated with the gut microbiome. The results of previous studies on the effectiveness of antibiotics and fecal macrobiota transplantation (FMT) are contradicting. Aims: to evaluate the effectiveness of wide-spectrum antibiotic regimens in acute severe colitis in an addition to standard corticosteroid therapy (UC and isolated "UC-like" Crohn's colitis). The secondary aim is to assess the outcome of FMT in those not responding to five days of therapy (in either arm). As an exploratory aim, any IBD patient with a resistant disease to at least two immunosuppressive medications, may be treated with either interventions.
