Abstract

Statin therapy is used ubiquitously to reduce cholesterol levels, and recent studies have revealed statin use may be associated with a reduced risk of inflammatory bowel disease (IBD). A comprehensive assessment of the literature was performed to investigate whether statin use may influence the risk of new-onset IBD. We searched the PubMed/MEDLINE, Cochrane, Web of Science, and Scopus online databases, for articles published up to July 31, 2020. Hazard ratios (HR) with 95% confidence intervals (CI) were used. We identified five retrospective studies, with seven arms, comprising >10 million participants, consisting of 89,324 cases of IBD (statin users: 14,494 versus non-users: 74,830) detected during a mean follow-up of 8.6 years. Overall, statin use was associated with a reduced risk of new-onset IBD (HR = 0.81; 95% CI, 0.63 to 1.06; P = 0.129, I2 = 81.3%). Pooled results indicated a non-significant reduced risk of new-onset CD (HR = 0.94; 95% CI, 0.72 to 1.25; P = 0.684, I2 = 85.9%) and new-onset UC (HR = 0.89; 95% CI, 0.70 to 1.12; P = 0.306, I2 = 92.5%) with statin use. Statin use may confer a protective effect in reducing the risk of new-onset IBD. Indeed, this study provides novel and intriguing insights into a potential preventive agent for IBD.
