This prospective study demonstrates a significant correlation between FC and endoscopic response to VDZ. FC < 200 μg/g prognosticate endoscopic response, and FC > 450 μg/g endoscopic non-response. An increase in FC of > 400 μg/g after induction indicates endoscopic loss of response. This simple FC algorithm may guide clinical decisions on the continuation and optimization of VDZ in inflammatory bowel disease patients.
