Changes in lipid and lipoproteins with long-term estrogen deficiency and hormone replacement therapy
Article Abstract:
Replacement therapy with the female hormone estrogen helps to protect against cardiovascular disease in women who are postmenopausal. Estrogen improves blood lipids by reducing the levels of total cholesterol and low-density lipoprotein (LDL) cholesterol, and by increasing high-density lipoprotein (HDL) cholesterol. This results in the improvement of the LDL/HDL ratio, or proportion of LDL relative to HDL. Another female hormone, progestogen, may be added to estrogen in hormone replacement therapy of postmenopausal women. However, progestogens may diminish the beneficial effects of estrogen and the overall effect of hormone replacement therapy against cardiovascular disease. The long-term effects of estrogens, progestogens, and androgens, which are male hormones, on blood lipids and lipoproteins were assessed in 556 postmenopausal women, who ranged in age from 24 to 85 years. These women were assessed for time periods ranging from 1 to 44 years. The lipid and lipoprotein levels before hormone replacement therapy were determined among 155 women after menopause. Shortly after menopause, the blood levels of total and LDL cholesterol increased, whereas HDL cholesterol did not change. The blood levels of triglycerides were associated with weight. Untreated women with normal weight had significantly lower blood triglyceride levels compared with hormone-treated women who weighed more than 200 pounds. HDL cholesterol levels were lower among women treated with C-21 and C-19 progestogens, but were not significantly different from levels among women using only estrogen. HDL cholesterol levels were reduced in all women who smoked, regardless of treatment. The findings suggest that progestogen does not alter the beneficial effects of estrogen on blood lipids and lipoproteins. (Consumer Summary produced by Reliance Medical Information, Inc.)
