Abstract

Bone mass, calcium and lipid metabolism, climacteric symptoms, bleeding, blood pressure, and weight changes were studied in 62 healthy postmenopausal women at 3-month intervals throughout 2 years of treatment with continuous estradiol valerate (2 mg) plus cyproterone acetate (1 mg), sequential estradiol valerate (2 mg) plus levonorgestrel (75 micrograms), or placebo. During the 2 years of the study, bone mineral content of the distal and ultradistal regions of the forearm (measured by single-photon absorptiometry) remained unchanged in the hormone groups, whereas bone mineral content at these sites decreased by 5 and 6%, respectively, in the placebo group. Bone mineral density in the spine (measured by dual-photon absorptiometry and dual-energy x-ray absorptiometry) increased by 3-4% in the hormone groups and decreased by 2% in the placebo group. Biochemical estimates of bone turnover (serum alkaline phosphatase and fasting urinary calcium/creatinine) decreased significantly to premenopausal levels in the hormone groups, but remained unchanged in the placebo group. Serum concentrations of total and low-density lipoprotein cholesterol were significantly reduced by 5-10% (P less than .05-.01) in the estradiol + cyproterone acetate group and by 10-15% (P less than .001) in the estradiol valerate + levonorgestrel group. There were no significant changes in high-density lipoprotein cholesterol in the hormone groups. Virtually no changes were observed in the placebo group. Climacteric symptoms and hot flushes were significantly reduced in both hormone groups compared with the placebo group.(ABSTRACT TRUNCATED AT 250 WORDS)
