Association Between ABCG2 Polymorphism and Statin-Induced Adverse Events: A Meta-Analysis

초록

Statins, widely used for preventing cardiovascular diseases due to their cholesterol-lowering effects, are associated with potential adverse reactions in some individuals, underscoring the need to understand the factors contributing to statin-related complications. The ATP-binding cassette subfamily G member 2 (ABCG2) gene, which encodes a multidrug transporter, has garnered attention due to its involvement in statin metabolism. Specifically, the rs2231142 polymorphism within ABCG2 has been implicated in altered drug metabolism and pharmacokinetics, potentially influencing statin-related toxicity. Despite previous investigations, findings regarding this association remain inconclusive. Thus, this systematic review and meta-analysis aimed to clarify the correlation between the rs2231142 polymorphism and statin-induced toxicity. Through a comprehensive literature search, seven eligible studies were identified and subjected to rigorous data extraction and quality assessment. Meta-analysis revealed a significant association between the rs2231142 polymorphism and an increased risk of overall statin-induced toxicity, including muscular and hepatic toxicity, with odds ratios of 2.6 and 2.7, respectively. These findings suggest a potential role for ABCG2 polymorphisms in statin-related adverse events and emphasize the importance of personalized treatment strategies in managing statin therapy.
