hormone replacement therapy and lipoprotein changes during menopause

to evaluate the effectiveness of conjugated estrogen (premarin) and progesterone in twenty-one postmenopausal women who had been menopause one year, we tested during a 6-month period the serum lipoprotein levels in subjects who offered by premarin in dosage of 0.625 milligram for days 1 to 25 and oral medroxy progestrone acetste for days 15 to 25 of a 30-day cycle. twenty-one subjects completed at least 6-month follow-up serum total cholesterol, low density lipoprotein (ldl) cholesterol, high density lipoprotein (hdl) cholesterol, very low density lipoprotein (vldl) cholesterol and triglycerid (tg) measurements by calorimetric method. the results, six months after treatment, is compared to before treatment. the median change in biochemical studies showed significant decrease in serum total cholesterol (248.85 compared with 229.4, p<0.001) serum ldl-cholesterol (155.7 compared with 130.6, p<0.05), but significant increase in serum hdl-cholesterol (53.46 compared with 61.46, p<0.05) tg and vldl levels did not occur. we concluded that conjugated estrogen is effective on serum total cholesterol, ldl and hldl cholesterol in postmenopausal women
