Abstract

Background

While statins are effective at managing lipid levels, there is growing evidence for new-onset diabetes mellitus (NODM). The insulin signalling pathway (ISP) inhibited by statins is one of the potential mechanisms; however, most studies have been limited to in vitro settings. Therefore, this study aimed to identify the genetic associations within the ISP-related genes and NODM.

Methods

We performed a retrospective analysis of samples collected prospectively from February 2021 to May 2021. Among ISP-related genes, we selected 11 candidate genes (IGF1, IGF2, IGF1R, INSR, IRS1, IRS2, PIK3CA, PIK3CB, PIK3R1, AKT1 and AKT2). An additional analysis was conducted comparing patients with DM prior to statin therapy and controls to determine whether the single nucleotide polymorphisms (SNPs) are specific to statin.

Results

A total of 602 patients were analysed, including 71 (11.8%) with statin-induced NODM. After adjustment, IGF1R rs2715439, INSR rs1799817, INSR rs2059807 and PIK3R1 rs3730089 were found to be independently associated with NODM. In an additional analysis, all SNPs that demonstrated an association with statin-induced NODM lost their significance in patients with DM prior to statin therapy.

Conclusion

This study revealed the ISP-related genetic effects, specifically involving genes such as INSR, IGF1R and PIK3R1, in the development of statin-induced NODM. Our findings suggest a potential mechanism of statin-induced NODM related to ISP-related genetic variants.
