摘要
Objectives: To compare the metabolic and endocrinological effects of estradiol valerate/cyproterone acetate (EV/CPA) to a regimen of conjugated estrogens/medroxyprogesterone acetate (CE/MPA) in postmenopausal women. Methods: Lipid profile, endocrinological parameters, coagulation factors, renin and angiotensinogen were followed in postmenopausal women randomized to EV/CPA or CE/MPA during 12 cycles. Results: Following 12 cycles of treatment, total plasma cholesterol decreased more with EV/CPA than with CE/MPA. Low-density cholesterol decreased with EV/CPA while it increased with CE/MPA. High-density cholesterol remained fairly unchanged, and triglycerides increased significantly in both groups. Estradiol and estrone levels increased significantly more with EV/CPA than with CE/MPA while the sex-hormone-binding globulin increased more with CE/MPA. Follicle stimulating and luteinizing hormone levels also decreased significantly. Total testosterone and dihydroepiandrosterone sulfate remained stable. Total levothyroxine serum levels increased significantly, but thyroid stimulating hormone and triiodothyronine levels remained stable. Coagulation parameters also remained stable. Angiotensinogen increased, while plasma renin activity and blood pressure remained unchanged. Conclusion: It is concluded that both EV/CPA and CE/MPA produce favourable metabolic effects. A better lipid profile, compatible with decreased cardiovascular risk, is observed with the EV/CPA regimen. Higher circulating estrogen levels may explain in part this observation.
