Associations of small dense low-density lipoprotein and adiponectin with complications of type 2 diabetes.

AbstractBackground: Small dense low-density lipoprotein (sd-LDL) has been demonstrated to be associated with cardiovascular diseases (CVD). The proposed atherogenic properties of hypoadiponectinemia might be mediated through increased sd-LDL. In this study, the associations of sd-LDL with cardiovascular and other complications of diabetes, and also with plasma levels of adiponectin, were investigated in diabetic patients. Methods: 173 patients, with documented type 2 diabetes mellitus, were enrolled in this cross-sectional study. Laboratory, anthropometric, and clinical characteristics were all determined. The presence of CVD, hypertention, and microalbuminuria were also evaluated. Homeostasis model assessment of insulin resistance was calculated. Results: Sd-LDL concentrations were significantly lower in patients with CVD than those without CVD (p = 0.020); and also lower in hypertensive patients relative to non-hypertensive ones (p = 0.008). Serum levels of adiponectin were significantly lower in patien...
