About

The purpose of this study is to assess the diagnostic value of microRNAs in IBD colon (ulcerative colitis or Crohn's disease) in adults as compared to healthy controls (and non-IBD colitis)

Full description

RATIONAL Inflammatory Bowel Disease (IBD) affects more than 200,000 people in France and 1.5 million in Europe. Difficulties in the management of IBD are related to the need for invasive tests for the diagnosis of IBD (endoscopy), partly explaining the delay in diagnosis, and the inability to distinguish early colonic Crohn's disease of ulcerative colitis (UC) in 10-30% of cases.

Recently, we identified real-time polymerase chain reaction (PCR), from healthy colonic mucosa of IBD patients, a molecular signature of IBD involving 10 microRNA (miRNA) Common (miR26a, miR29a, miR29b, miR126 * miR15a, miR127-3p, miR324 -3p, miR30c, miR185, miR196a) and 15 colic chronic disease (MC) and ulcerative colitis (RCH) discriminating microRNA (miR-142-3p, miR-142-5p, miR-146a, miR-146b-5p, miR150, miR-181d, miR-182, miR199a -3p, miR199a-5p, miR199b-5p, miR-203, miR223, miR-299-5p, miR320a, miR-328).

TYPE OF STUDY : multicenter diagnostic evaluation Study

MAIN PURPOSE OF THE STUDY : To evaluate the diagnostic value of microRNA in colonic IBD (ulcerative colitis or Crohn's disease) in adults as compared to healthy controls (and non-IBD colitis)

SECONDARY OBJECTIVES :

  • assess the ability of microRNA to discriminate a colic chronic disease (MC) of ulcerative colitis (RCH) in adults
  • evaluate the diagnostic value of microRNA in inflammatory colitis child
  • explore the possibility of measuring miRNA of interest in the stool
