Diabetic Dyslipidemia: From Evolving Pathophysiological Insight to Emerging Therapeutic Targets

Diabetic dyslipidemia is characterized by hepatic very low density lipoprotein (VLDL) and intestinal chylomicron overproduction, reduced high density lipoprotein cholesterol (HDL-C) level, increased propensity of small dense LDL (sdLDL) and increased postprandial lipemia. This dyslipidemic profile is also strongly linked to other features of the metabolic syndrome. Diabetic dyslipidemia is a well-recognized risk factor for atherosclerotic cardiovascular diseases. Currently, statins remain the first line therapy primarily through reducing the atherogenic LDL. Clinical trials on other lipid modifying agents were met with variable success in selective patient populations. Emerging new insights into the pathophysiology of lipid metabolism, in general, and diabetic dyslipidemia, in particular, have opened up potentially novel therapeutic strategies to further reduce the risk associated with diabetic dyslipidemia and insulin resistant state.
