Role of plasma adiponectin on the HDL-cholesterol raising effect of atorvastatin in patients with type 2 diabetes

ABSTRACTObjective: Adiponectin, secreted by adipose tissue, plays an important role in lipoprotein metabolism and also affects carbohydrate and insulin pathways. We studied the effects of atorvastatin treatment on plasma adiponectin and high density cholesterol (HDL) levels in patients with type 2 diabetes.Research design and methods: In the ‘Diabetes Atorvastatin Lipid Intervention’ (DALI) study, a randomized placebo-controlled study on the effects of atorvastatin treatment in 194 patients with type 2 diabetes and mildly elevated plasma triglycerides, adiponectin levels, lipoproteins, cholesteryl ester transfer protein (CETP) mass, as well as postheparin lipoprotein lipase (LPL) and hepatic lipase (HL) activities were assessed at baseline and after 6 months of treatment (placebo, 10 mg or 80 mg atorvastatin).Results: At baseline, plasma adiponectin levels were positively associated with HDL cholesterol (r = 0.40, p < 0.001), and apoA-I (r = 0.38, p < 0.001) in both males and females. Adiponectin was nega...
