Abstract

It remains unclear whether the increased risk of new-onset type 2 diabetes (T2D) seen in statin users is due to low LDL-C concentrations, or due to the statin-induced proportional change in LDL-C. In addition, genetic instruments have not been proposed before to examine whether liability to T2D might cause greater proportional statin-induced LDL-C lowering. Using summary-level statistics from the Genomic Investigation of Statin Therapy (GIST, nmax = 40,914) and DIAGRAM (nmax = 159,208) consortia, we found a positive genetic correlation between LDL-C statin response and T2D using LD score regression (rgenetic = 0.36, s.e. = 0.13). However, mendelian randomization analyses did not provide support for statin response having a causal effect on T2D risk (OR 1.00 (95% CI: 0.97, 1.03) per 10% increase in statin response), nor that liability to T2D has a causal effect on statin-induced LDL-C response (0.20% increase in response (95% CI: -0.40, 0.80) per doubling of odds of liability to T2D). Although we found no evidence to suggest that proportional statin response influences T2D risk, a definitive assessment should be made in populations comprised exclusively of statin users, as the presence of nonstatin users in the DIAGRAM dataset may have substantially diluted our effect estimate.

Scatter plots of instrument-outcomes (y-axis) against individual instrument-exposure (x-axis) per-allele effects, shown separately for statin response (left panel) and liability of type 2 diabetes instruments (T2D, right panel). The filled dots correspond to the restricted lists of variants (see text), while the full set included all dots. The lines correspond to the inverse-variance weighted combined MR estimator, for the restricted (dashed line) and full set of instruments.

Funnel plots of individual causal effect estimates (Wald ratios) for statin response on type 2 diabetes (T2D, left panel), and liability to T2D on statin response (right panel). The black dots correspond to the restricted lists of variants (see text), while the full set included all dots. The lines correspond to the inverse-variance weighted combined MR estimator, for the restricted (dashed) and full set of instruments.
