Debate: Lipid-lowering Therapies and Diabetes Development.

Purpose of review: This review explores the relationship between lipid-lowering therapies, particularly statins, and the risk of new-onset diabetes (NOD). It examines the underlying mechanisms and evaluates whether other lipid-lowering agents present similar risks.

Recent findings: Recent meta-analyses further underscore a dose-dependent increase in NOD risk with statin therapy, particularly with high-intensity statins. In contrast to other LDL-cholesterol lowering drugs and their impact on lipid metabolism in the liver, genetic and experimental studies indicate that statins may impair insulin secretion through various mechanisms, including alterations in small G protein function, calcium signaling, and cholesterol homeostasis in pancreatic beta cells. This might contribute to the increased risk of NOD. Statins effectively reduce cardiovascular events but increase the risk of NOD, potentially via intracellular pathways affecting liver and beta-cell function. Despite the cardiovascular benefits of statins, personalized treatment strategies and alternative lipid-lowering therapies may offer safer options for patients at risk of diabetes, potentially shaping future clinical guidelines and therapeutic approaches.
