Abstract

Objective: It is difficult to predict relapse in quiescent ulcerative colitis (UC), but newer endoscopic and histological indices could improve this. This study aimed to determine in UC patients in clinical remission (1) the prevalence of active endoscopic and histological disease; (2) the correlation between endoscopic and histological scores; and (3) the predictive power of these scores for clinical relapse.

Design: This multicenter prospective cohort study conducted by the Crohn's and Colitis Foundation Clinical Research Alliance included 100 adults with UC in clinical remission undergoing surveillance colonoscopy for dysplasia. Endoscopic activity was assessed using the Mayo endoscopic score (MES), ulcerative colitis endoscopic index of severity (UCEIS), and ulcerative colitis colonoscopic index of severity (UCCIS). Histology was assessed with the Riley index subcomponents, total Riley score, and basal plasmacytosis.
