Predicting the Course of Disease in Hospitalized Patients With Acute Severe Ulcerative Colitis.

ABSTRACT

BACKGROUND: Up to one-third of patients with acute severe ulcerative colitis (ASUC) will fail intravenous steroid (IVS) treatment, requiring rescue therapy with cyclosporin (Cys), infliximab (IFX), or colectomy. Although several scores for predicting response to IVS exist, formal comparison is lacking. METHODS: We performed a single-center retrospective analysis including 489 patients with ulcerative colitis. In patients with ASUC, the Mayo endoscopic subscore and the Oxford, Edinburgh, and Lindgren scores were assessed. Outcomes included IVS failure, need for rescue medical therapy, and surgery. RESULTS: One hundred twelve patients presented with ASUC. Forty-two percent showed an incomplete or absent response to IVS, 28.6% received rescue therapy (22 with IFX, 10 with Cys, and 1 with sequential treatment), and 26.8% required surgery. The Lindgren score showed the highest performance in predicting IVS failure (are under the curve [AUC], 0.856; 95% confidence interval [CI], 0.784-0.928), need for medical rescue therapy (AUC, 0.826; 95% CI, 0.749-0.902), and surgery (AUC, 0.836; 95% CI, 0.712-0.960; all P < 0.01). CONCLUSIONS: In our series, the Lindgren score was superior to the Mayo, Oxford, and Edinburgh scores in predicting major clinical outcomes in ASUC.
