Smoking and Early Infliximab Response in Crohn's Disease: a Meta-analysis

摘要

Background: Infliximab is used to treat moderate to severe Crohn's disease (CD), but its efficacy varies. Although cigarette smoking worsens CD, its impact on the infliximab response is unknown. We conducted a systematic review and meta-analysis of clinical trials to determine the effect of smoking on the induction response to infliximab.
