Remote Monitoring of IBD

Comparison of Patient Reported Disease Activity Scores Combined With Fecal Calprotectin Home Tests for Remote Monitoring of IBD Patients: a Multicenter Prospective Validation Study

Crohn's disease (CD) and ulcerative colitis (UC) are chronic inflammatory bowel diseases (IBD) with a heterogeneous disease course. Recurrent mucosal inflammation or chronic subclinical inflammation results in damage to the bowel and complications like stenosis, fistula and colorectal cancer. Therefore, tight control of mucosal inflammation is important to prevent complications.

The goal of this multicenter observational cohort study is to determine the best remote monitoring tool for predicting mucosal inflammation in adult patients with inflammatory bowel disease, relative to the gold standard endoscopy.

Participants will be asked to fill out questionnaires regarding disease activity (MIAH, mHI, IBD-control, Manitoba IBD Index, p-HBI/p-SCCAI), perform a FC home test and collect one stool sample for routine laboratory calprotectin measurement, before the start of the bowel preparation for the ileocolonoscopy. During this ileocolonoscopy, endoscopic disease activity will be determined.

• Smartphone with internet access (for use FC home test)

Exclusion Criteria:

• Unclassified IBD
• Ileostomy, colostomy, ileoanal pouch anastomosis or ileorectal anastomosis
