Biomarkers for Disease Activity in Inflammatory Bowel Disease.

This summary aims to guide clinicians in applying biomarker-based monitoring strategies for personalized, evidence-based care. It provides a comprehensive update on established and emerging blood, stool, and radiological biomarkers for assessing disease activity in inflammatory bowel disease as part of a biomarker-guided treat-to-target approach endorsed by STRIDE II consensus, including in patients with Crohn disease, ulcerative colitis, and in special populations such as those with an ileoanal pouch, ostomy, perianal fistulizing Crohn disease, in pregnancy and in detecting postoperative recurrence of Crohn disease.
