Fecal Calprotectin to Detect Inflammatory Bowel Disease in Juvenile Idiopathic Arthritis

J Rheumatol. 2018 Oct;45(10):1418-1421. doi: 10.3899/jrheum.171200. Epub 2018 Jun 15.

Abstract

Objective: This study aimed to test fecal calprotectin (FC) as a screening tool to identify inflammatory bowel disease (IBD) among patients with juvenile idiopathic arthritis (JIA).

Methods: FC level < 100 g/kg was considered normal. Patients with 2 consecutive FC dosage ≥ 100 g/kg underwent endoscopic evaluation.

Results: There were 113 patients with JIA enrolled. FC was raised in 7 patients out of 113. All patients had IBD. In 3/7 patients, high FC levels were the only sign consistent with IBD.

Conclusion: FC is a useful, economical, and noninvasive diagnostic tool to identify JIA patients with underlying IBD.
