Overview

Inflammatory Bowel Diseases (IBD) go through two phases: flare and remission. Prediction of flares and identification of patients in remission but at high risk of flare are a major issue when taking care of IBD patients.

Considering close interactions between sleep, immunity and intestinal inflammation, sleep disorders could be a predictor of flares.

The purpose of this study is to demonstrate that sleep efficacy decreases before IBD flare.

Patients in remission will be assessed for IBD symptoms (activity scores, biological factors) and sleep disorders (actigraphy, DREEM®, questionnaires) during one year.
