Oestrogen--progestin therapy and the lipid balance of post-menopausal women.
The lipid and lipoprotein profiles of 20 post-menopausal women treated with cyclic conjugated oestrogens (0.625 or 1.25 mg) and medroxyprogesterone acetate (10 mg for 7 days) were compared to those of 18 untreated women of similar age and menopausal status. No statistically significant between-group differences were observed during the 18-mth period for cholesterol, triglycerides or lipoprotein distribution. After 12 mth, a significant shift in lipoprotein distribution manifested in the treated and untreated groups. The proportion of high-density lipoproteins significantly increased and that of the low-density lipoproteins significantly decreased. Although the shift was more pronounced in the treated group, there was no significant difference between the treated and untreated groups. These results indicated that such relatively nonandrogenic progestins as medroxyprogesterone acetate, have no adverse effects on the lipid milieu of post-menopausal women when used with long-term oestrogen therapy.
