Early Changes in Inflammatory Indices and Healing in IBD
Early Kinetic Changes in Blood-Based Inflammatory Indices as Predictors of Endoscopic and Histological Healing in Patients With Inflammatory Bowel Disease
This prospective observational study aims to evaluate early changes in blood-based inflammatory indices during the first 4 weeks after treatment initiation or escalation and their relation to endoscopic and histological healing at 12 to 16 weeks in adult patients with inflammatory bowel disease.
研究概览
详细说明
Objective assessment of treatment response is important in inflammatory bowel disease. This prospective cohort study will include adult patients with ulcerative colitis or Crohn's disease who are starting or escalating medical therapy.
Blood-based inflammatory indices will be assessed at baseline and at 4 weeks. Endoscopic and histological outcomes will be evaluated at approximately 12 to 16 weeks.
