Fecal Calprotectin to Detect Inflammatory Bowel Disease in Juvenile Idiopathic Arthritis

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 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.
