Inflammatory Bowel Disease (IBD)
Conditions
Keywords
cohort, BEV, intestinal dysbiosis
Brief summary
The objective of this study is to constitute cohorts of IBD versus non-IBD patients to identify (a) new biomarker(s) of intestinal dysbiosis associated with inflammatory bowel disease, and develop a prototype for assaying such marker(s) in blood.
Interventions
Collection of biological samples from the same cohorts: faeces, serum, intestinal biopsies

Study design
Intervention model description
Prospective, monocentric, study aiming to recruit 2 types of patients (60 inflammatory bowel disease (IBD) suffering patients versus 60 control patients without IBD nor any other known intestinal pathology).
