It is uncertain whether mucosal healing after the first course of corticosteroids therapy predicts outcome in patients with ulcerative colitis (UC). We evaluated whether early clinical and endoscopic responses to this therapy are associated with late outcomes in UC. Patients with newly diagnosed UC who were prescribed corticosteroid therapy (n = 157) were followed up for 5 years. They were evaluated using clinical (Powel-Tuck [PT]) and endoscopic (Baron) indexes after 3 and 6 months, then every 6 months. Outcomes at month 3 (early response) were used to identify patients with complete (group A: PT, 0-1; Baron, 0), partial (group B: PT, 0-1; Baron, 1-3), or no response (group C: persistence of clinical and endoscopic activity). The association between early and late outcomes was assessed. After 5 years, there were significant differences between complete and partial responders in the rates of hospitalization (25% in group A vs 48.7% in group B; P = .0152; odds ratio [OR], 2.85; 95% confidence interval [CI], 1.21-6.72), immunosuppression therapy (5% in group A vs 25.6% in group B; P = .0030; OR, 6.55; 95% CI, 1.67-25.67), colectomy (3.3% in group A vs 18.0% in group B; P = .0265; OR, 6.34; 95% CI, 1.24-32.37), and their combination (26.7% in group A vs 48.7% in group B; P = .0249; OR, 2.61; 95% CI, 1.12-6.11). After multivariate analysis, lack of mucosal healing was the only factor associated with negative outcomes at 5 years (immunosuppressors: hazard risk [HR], 10.581; 95% CI, 2.193-51.039; P = .0033; hospitalization: HR, 3.634; 95% CI, 1.556-8.485; P = .0029; colectomy: HR, 8.397; 95% CI, 1.278-55.186; P = .0268). No mucosal healing after corticosteroid therapy is associated with a more aggressive disease course. Copyright © 2011 AGA Institute. Published by Elsevier Inc. All rights reserved.
