Eficacia y seguridad del factor de necrosis tumoral (alfa) bloqueadores para la colitis ulcerosa: una revisión sistemática y meta-análisis de ensayos controlados aleatorios publicados

To evaluate the efficacy and safety of TNF-α blockers for ulcerative colitis. A systematic search for randomized controlled trials (RCTs) of TNF-α blockers for treatment of ulcerative colitis (UC) were performed in PubMed, Web of Science, Embase and cochrane clinical trial. We estimated Pooled estimates of the odds ratio (OR) and relevant 95% confidence interval (CI) using fixed effects model or random effects model as appropriate. Heterogeneity, publication bias, and subgroup analyses were conducted. Nine randomized controlled studies met the selection criteria with a total of 2518 patients. Five studies compared Infliximab with placebo. Two studies compared Infliximab to corticosteroids. Two studies compared Adalimumab to placebo. One study compared subcutaneous golimumab to placebo. Short-term response, short-term remission, long-term remission and mucosal healing were better in the TNF-α blocker group than in the control group (p < 0.05). TNF-α blockers decreased the colectomy rate and serious adverse reactions (p < 0.05). The TNF-α blockers were superior to controls in achieving short-term clinical response/remission, long-term remission and mucosal healing and decreased the colectomy rate and serious adverse reactions.
