Safety of biological therapies in ulcerative colitis: An umbrella review of meta-analyses

Pubmed and Scopus databases were systematically searched through November 2017 to identify meta-analyses of RCTs that have investigated potential harms of biological agents (adalimumab, golimumab, infliximab, and vedolizumab) in patients with UC. Ten eligible meta-analyses were included. The body of available evidence supports the safety of biologic therapies in UC. Further research is needed to clarify the risk of any infection with biologics, for elderly and high-risk groups, for longer-term effects, and for head-to-head comparisons between the different biologics.
