Objective: To compare the effects of 17-oestradiol plus dydrogesterone with conjugated equine oestrogens plus medroxyprogesterone acetate on serum lipids, apolipoproteins and lipoprotein(a) in postmenopausal women. Methods: A multi-centre, prospective, randomised, double-blind, comparative one-year study in 362 healthy postmenopausal women aged 39–74 years with an intact uterus. Fasting blood samples were taken at baseline and after 28 and 52 weeks of treatment. Participants received daily oral treatment with continuous combined 1 mg micronised 17-oestradiol/5 mg dydrogesterone (E/D: n = 180) or 0.625 mg conjugated equine oestrogens/5 mg medroxyprogesterone acetate (CEE/MPA:n = 182). Results: Significant differences between the two groups after 52 weeks were observed for total cholesterol (E/D: −1.7%; CEE/MPA: −7.3%), LDL-cholesterol (E/D: −4.5%; CEE/MPA: −11.3%), HDL-cholesterol (E/D: +15.3%; CEE/MPA: +7.5%), triglycerides (E/D: +9.8%; CEE/MPA: +16.6%), VLDL-triglycerides (E/D: −3.3%; CEE/MPA: +10.0%), lipoprotein(a) (E/D: 0.0%; CEE/MPA: −25.2%) and for the ratio apolipoprotein B/LDL-cholesterol (E/D: +0.9%; CEE/MPA +5.9%). Conclusions: E/D and CEE/MPA differ in their anti-atherogenic effects on lipids and lipoproteins. This however can not easily be translated to differences in clinical cardiovascular outcomes. © 2004 Elsevier Ireland Ltd. All rights reserved.
