This study investigated the effects of oral combined hormone replacement therapy (OCHRT) on lipid concentrations and subpopulation distribution of lipoproteins in nine postmenopausal women with type 2 diabetes mellitus and moderate glycemic control. After 16 weeks of continuous daily therapy of conjugated estrogens 0.625 mg and medroxyprogesterone 2.5 mg, the mean concentration of high-density lipoprotein (HDL) cholesterol showed a statistically significant increase of 16.7%, predominantly in the HDL2 subfraction. No statistically significant changes in mean concentrations of total cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, very low-density lipoprotein (VLDL) triglycerides, apolipoprotein A1, or apolipoprotein B were evident. Likewise, no changes were found in the average diameter of VLDL, LDL, or HDL particles; triglyceride concentrations of VLDL subfractions; cholesterol concentrations of LDL subfractions; or chemical composition of plasma LDL. These findings lend further support to the use of OCHRT in postmenopausal women with diabetes to decrease their risk for coronary artery disease. |
