Background: Hormone replacement therapy (HRT) in post-menopausal women carries an increased risk of cardiovascular disease due to an unfavorable effect on lipid profile. Thus, HRT treatment increases concentrations of very-low-density-lipoprotein-triglycerides (VLDL-TGs) which have been demonstrated to possess atherogenic properties. However, the exact mechanisms whereby VLDL-TG concentrations are increased by estradiol are not fully understood. Estradiol acts on both rapid re...

Context: Thiazolidiones (TZD) improves insulin sensitivity in type 2 diabetes via effects on fat metabolism, whereas growth hormone (GH) stimulates lipolysis and induces insulin resistance.Objective: To evaluate the effects of TZD on fat metabolism and insulin sensitivity in GH-treated GH deficient (GHD) patients.Design: Randomized, placebo-controlled, double-blind parallel-group study including 20 GHD patients on continued GH repl...
