A Cochrane review [Abstract] 1 included 7 studies with a total of 860 subjects. In patients with moderate to severe ulcerative colitis whose disease was refractory to conventional treatment using corticosteroids and/or immunosuppressive agents, infliximab (three intravenous infusions at 0, 2, and 6 weeks) was more effective than placebo in inducing clinical remission (RR 3.22, 95% CI 2.18 to 4.76); inducing endoscopic remission (RR 1.88, 95% CI 1.54 to 2.28); and in inducing clinical response (RR 1.99, 95% CI 1.65 to 2.41) at 8 weeks. A single infusion of infliximab was also more effective than placebo in reducing the need for colectomy within 90 days after infusion (RR 0.44, 95% CI 0.22 to 0.87).
