Infliximab Versus Cyclosporine For Severe Ulcerative Colitis Refractory To Steroids A Protocol For Systematic Review And Meta-Analysis

Background: Infliximab and cyclosporine are two main therapies in treating acute severe ulcerative colitis (ASUC), our objective is to assess the effectiveness and safety of cyclosporine (CSA) versus infliximab (IFX) as rescue agents in patients with steroid-refractory ulcerative colitis (UC).Methods: We will search three databases from inception to May 2018, and 19 studies are identified that infliximab and cyclosporine as a treatment in steroid-refractory UC patients. The primary outcome was short-term response to treatment. Secondary outcomes included the rates of colectomy at 3 months, 12 months, 36 months, adverse drug reactions and mortality in those who received rescue therapy.Results: This update review will provide a high quality synthesis of current evidence of two treatment for steroid-refractory ulcerative colitis. The definition of severe colitis is according to Truelove and Witts' criteria.Conclusions: In the treatment of steroid-resistant ulcerative colitis with infliximab and cyclosporine, there is no difference between the two treatments on short-term and long-term results.
