Overview
This study aims to assess the prevalence of exocrine pancreatic insufficiency (EPI) in a population of patients with active Crohn's disease. Studies already describe a prevalence rate around 18-66%. In this multicentric prospective study, we plan to compare EPI's prevalence at week 0 and week 14 of an induction phase of a biological therapy. The biological therapy will be initiate for an active Crohn's disease. Secondary outcomes will be: malnutrition's prevalence, and Crohn's disease activity level.
