Plain language summary
Intravenous steroids are the first-line therapy for ulcerative colitis (UC) patients who are hospitalised during a severe UC flare-up. In the 40% of patients who don’t respond to steroids, the drugs ciclosporin and infliximab have been found to be efficient in preventing surgery to remove part or all of the colon, but there is a lack of data on the long-term outcomes of using these medications in UC patients. The aim of this study was to assess long-term outcome of patients included in a randomised trial comparing ciclosporin and infliximab. Between 2007 and 2010, 115 patients with UC that did not respond to steroids were randomised to receive ciclosporin or infliximab in association with azathioprine. Patients were followed to January 2015 or death. After a median follow-up of 5.4 years, colectomy-free survival rates at 1 and 5 years were, respectively, 70.9% and 61.5% in patients who received ciclosporin and 69.1% and 65.1% in those who received infliximab. Long-term colectomy-free survival was independent from initial treatment. However, a higher proportion of patients initially treated with ciclosporin needed a new treatment compared with those who received infliximab first. The researchers concluded that these results further confirm a similar efficacy and good safety profiles of both drugs.
Abstract
OBJECTIVE Ciclosporin and infliximab have demonstrated short-term similar efficacy as second-line therapies in patients with acute severe UC (ASUC) refractory to intravenous steroids. The aim of this study was to assess long-term outcome of patients included in a randomised trial comparing ciclosporin and infliximab. DESIGN Between 2007 and 2010, 115 patients with steroid-refractory ASUC were randomised in 29 European centres to receive ciclosporin or infliximab in association with azathioprine. Patients were followed until death or last news up to January 2015. Colectomy-free survival rates at 1 and 5 years and changes in therapy were estimated through Kaplan-Meier method and compared between initial treatment groups through log-rank test. RESULTS After a median follow-up of 5.4 years, colectomy-free survival rates (95% CI) at 1 and 5 years were, respectively, 70.9% (59.2% to 82.6%) and 61.5% (48.7% to 74.2%) in patients who received ciclosporin and 69.1% (56.9% to 81.3%) and 65.1% (52.4% to 77.8%) in those who received infliximab (p=0.97). Cumulative incidence of first infliximab use at 1 and 5 years in patients initially treated with ciclosporin was, respectively, 45.7% (32.6% to 57.9%) and 57.1% (43.0% to 69.0%). Only four patients from the infliximab group were subsequently switched to ciclosporin. Three patients died during the follow-up, none directly related to UC or its treatment. CONCLUSIONS In this cohort of patients with steroid-refractory ASUC initially treated by ciclosporin or infliximab, long-term colectomy-free survival was independent from initial treatment. These long-term results further confirm a similar efficacy and good safety profiles of both drugs and do not favour one drug over the other.
