Abstract
BACKGROUND AND AIMS Infliximab rescue therapy is effective in patients with corticosteroid refractory acute severe ulcerative colitis, but predictors of response remain poorly understood. We aimed to identify predictors of colectomy in this high-risk patient population. METHODS Patients hospitalized with acute severe ulcerative colitis who received infliximab after failing intravenous corticosteroid therapy between July 2012 and June 2017 were retrospectively identified. Stepwise regression with backward elimination was used to identify predictors of colectomy at 90 days and 1 year. Ninety-day and 1-year colectomy rates were compared between the patients who received 5 mg/kg and 10 mg/kg IFX rescue dose. RESULTS Sixty-three patients met the eligibility criteria. Twenty-nine patients received 5 mg/kg, and 34 received 10 mg/kg infliximab dose. Serum albumin on admission (OR 0.10; p = 0.04) and band neutrophil percentage at the time of infliximab administration (OR 1.21; p = 0.02) were independent predictors of 90-day colectomy. A combination of serum albumin ≤ 2.5 g/dl and band neutrophil count ≥ 13% had a 100% positive predictive value for 90-day colectomy. Unadjusted 90-day and 1-year colectomy rates were similar in the 5 mg/kg and 10 mg/kg infliximab groups. After adjusting for confounding factors, 10 mg/kg infliximab dose was potentially protective for 90-day (OR 0.07; p = 0.06) but not for 1-year colectomy (OR 0.19; p = 0.16). CONCLUSIONS Bandemia and low serum albumin are independent predictors of failure of infliximab rescue therapy in acute severe ulcerative colitis. Serum albumin ≤ 2.5 g/dl and band neutrophil count ≥ 13% had a 100% positive predictive value for 90-day colectomy.
