Journal of Crohn's and Colitis(2023)
摘要
Abstract Background In steroid refractory acute severe ulcerative colitis (ASUC), cyclosporine or infliximab are potential rescue treatments to avoid colectomy. Our objective is to assess the short-term and long-term efficacy and safety of cyclosporine versus infliximab as rescue agents. Methods We performed a retrospective analysis of 121 patients admitted with ASUC to a single gastroenterology centre during 2010-2020. ASUC was defined by the Truelove & Witts criteria. Primary outcome was short-term colectomy-free rate, secondary outcomes were severe adverse events, re-hospitalization or need of treatment with steroids within 2 years due to flare ups and colectomy rate at 2-year follow-up. Results 119 patients initially received intravenous corticosteroids, while 2 patients underwent emergency colectomy on the first day. Sixty-four (53%) were females, median age of all patients was 33 (IQR 27-49) years. 66 (55%) patients responded to intravenous corticosteroids (IVS), while 53 (45%) failed to respond to steroid therapy: 45 (37%) patients received second-line rescue therapy (29 with cyclosporine, 16 with infliximab). Evaluating the short-term efficacy of treatment there was no significant difference between cyclosporine and infliximab: during admission colectomy was performed in 10.3% vs. 12.5% of patients, respectively (p=0.826). In terms of long-term outcomes, the colectomy rate was higher in the infliximab group at 2-year follow-up, although the difference did not reach statistical significance (10.3% vs. 31.2%, p=0.079). The need for oral steroids during follow-up was comparable in both groups (38,5% vs. 50%, p=0.481). Comparing patients who did not undergo colectomy, patients in the infliximab group were more often re-hospitalized due to the need for IVS at 2-year follow-up (7.7% vs. 50%, p=0.002). No severe side effects due to infliximab and cyclosporine were observed. Conclusion In the treatment of steroid refractory ASUC infliximab and cyclosporine were equally effective in short-term period and there was no difference in safety, however cyclosporine treated patients trended to have better long-term outcomes, with significantly rarer re-hospitalization. Additional analysis is needed for other factors that may have contributed to differences in long-term outcomes between the cyclosporine and infliximab groups.
