Background/AimsIn patients with corticosteroid-refractory ulcerative colitis (UC), cyclosporine or infliximab may be added to the treatment regimen to induce remission. Here, we aimed to compare the efficacy of cyclosporine and infliximab.MethodsBetween January 1995 and May 2012, the medical records of 43 patients with corticosteroid-refractory UC who received either infliximab or cyclosporine as a rescue therapy at a tertiary care hospital in Korea were reviewed.ResultsAmong the 43 patients, 10 underwent rescue therapy with cyclosporine and the remaining 33 patients received infliximab. A follow-up of 12 months was completed for all patients. The colectomy rate at 12 months was 30% and 3% in the cyclosporine and the infliximab groups, respectively (p=0.034). However, the Cox proportional hazard model indicated that the treatment of rescue therapy was not an independent associate factor for preventing colectomy (p=0.164). In the subgroup analysis, infliximab with azathioprine was superior to cyclosporine for preventing colectomy (hazard ratio of infliximab with azathioprine compared with cyclosporine only, 0.073; 95% confidence interval, 0.008 to 0.629).ConclusionsNo difference between infliximab and cyclosporine with respect to preventing colectomy was noted. However, infliximab with azathioprine may be more effective than cyclosporine alone for preventing colectomy.
