Resolution of rectal bleeding by day 7 in acute severe ulcerative colitis is prognostic for post-discharge corticosteroid free clinical remission and endoscopic improvement.

ABSTRACT

This study assesses two different disease activity measures, the MTWSI and the partial Mayo score, in hospitalized acute severe UC patients for prediction of post-discharge corticosteroid-free clinical remission and endoscopic improvement to help guide future considerations for disease activity assessment. In this post-hoc analysis from the TRIUMPH trial, these results suggest resolution of Mayo rectal bleeding sub-score may have high prognostic utility and could be considered as a primary endpoint for hospitalized UC trials. The study underscores the need for further research on patient-reported outcomes and endoscopic indices in larger populations for inpatient UC trials.
