Menopause-dependent plasma lipoprotein alterations in diuretic-treated women.
The effects of chlorthalidone, 100 mg/d given for 6 weeks, on serum lipids and lipoproteins were assessed in 22 premenopausal and 18 postmenopausal women. In the latter, chlorthalidone significantly increased total serum cholesterol (13%, p less than 0.001), low-density-lipoprotein (LDL) cholesterol (21%, p less than 0.001) and apoprotein B (16%, p less than 0.05). In contrast, these values were not altered in the premenopausal group. Levels of LDL cholesterol, high-density-lipoprotein cholesterol, total and very-low-density triglycerides, apoproteins A1 and A2, and plasma volume, plasma glucose, insulin, epinephrine, estradiol, and free fatty acids were unchanged in both groups. Chlorthalidone-induced changes in levels of LDL cholesterol did not correlate significantly with variations in blood pressure, plasma potassium, uric acid, renin, aldosterone, or norepinephrine levels. These findings indicate that the thiazide-like diuretic chlorthalidone increases serum LDL cholesterol in postmenopausal but not in premenopausal women.
