Early Sonographic Improvement Predicts Clinical Remission and Mucosal Healing With Molecular-Targeted Drugs in Ulcerative Colitis.

ABSTRACT:

Background and aims

Predicting the efficacy of molecular-targeted drugs (MTDs) is an unmet need in the treatment of ulcerative colitis (UC). Intestinal ultrasound (IUS) can be used to safely and repeatedly assess UC activity.

Methods

Thirty-eight patients who started MTD therapy for active UC and underwent IUS at baseline and 3 months after starting therapy were analyzed. Steroid-free clinical remission (SFCR) and endoscopic improvement (EI) at 6 months were defined as a Lichtiger index of ≤3 and Mayo endoscopic subscore of ≤1 while continuing the MTD without steroid induction or surgery. Sonographically estimated EI (SE-EI) at 3 months was assessed based on a Milan Ultrasound Criterion of ≤6.2 and Kyorin Ultrasound Criterion for UC (bowel wall thickness of <3.8 mm and submu
