ABSTRACT
Background:
In ulcerative colitis (UC), endoscopic improvement, defined as a Mayo Endoscopic Score (MES) of 0 or 1, is a target of treatment. The aim of our study was to evaluate the risk of clinical relapse between patients with an MES of 0 or 1 and determine if histologic activity using the Robarts Histopathologic Index (RHI) was predictive of clinical relapse.Methods:
UC patients with an MES score of 0 or 1, no prior colectomy, and at least 1 year of outpatient follow-up after colonoscopy were included. Demographic, clinical characteristics, and clinical relapse were retrospectively collected. Biopsy specimens were read by a gastrointestinal pathologist. Primary outcome was defined as a composite of relapse requiring change in medical therapy, new steroid use, UC-related hospitalization, and/or colectomy.Results:
Four hundred and forty-five UC patients were identified. Ninety-five percent of patients with MES 0 were in histologic remission by the RHI whereas only 35% of patients with MES 1 were in histologic remission. Twenty-six percent of patients experienced a clinical relapse; patients with MES 1 or RHIâ >â 3 were significantly more likely to relapse (Pâ <â .01) compared to patients with MES 0 or RHIâ ≤â 3. When patients were stratified into 4 groups (MES 0, RHIâ ≤â 3; MES 0, RHIâ >â 3; MES 1, RHIâ ≤â 3; MES 1, RHIâ >â 3) and adjusted for age and sex, RHIâ >â 3 was predictive of relapse (Pâ =â .008).Conclusions:
UC patients with endoscopic improvement have a high rate of clinical relapse over time. Histologic activity is a predictor of clinical relapse.
