Impact of biologic therapies and small molecules on the risk of major adverse cardiovascular events in patients with inflammatory bowel diseases: Systematic review and meta-analysis of randomised controlled trials.

INTRODUCTION: The aim of this study is to estimate the risk of major adverse cardiovascular events (MACEs) in adult patients with inflammatory bowel disease (IBD) treated with biologic therapies and small molecules.

METHODS: Databases were searched up to July 2022 to identify eligible studies that assessed the risk of MACEs in patients (age ≥18 years) with IBD treated with treated with biologic therapies and small molecules. Primary outcome was the rate of MACEs observed in patients receiving biologic or small molecules therapies during induction and maintenance phases of RCTs.

RESULTS: In total 64 studies were included in the analysis. 22 RCTs involving 12196 patients with Crohn's disease (CD) were included and 32 RCTs involving 22,007 patients with ulcerative colitis (UC). In patients with CD, risk of MACE was not higher than placebo during induction or maintenance phases, infliximab (OR 0.63, 95% CI 0.07-6.14) and ustekinumab (OR 0.50, 95% CI 0.03-8.04). In patients with UC, risk of MACE was not higher than placebo, tofacitinib (OR 1.30, 95% CI 0.15-11.21) and upadcitinib (OR 0.50, 95% CI 0.03-7.97) during induction or maintenance.

CONCLUSION: The use of biologic therapies and small molecules among adult patients with IBD had no significant impact on the risk of MACEs during induction and maintenance period of RCTs. Real world data is warranted to asses long term risks.
