Abstract

The effect of cholecalciferol and estrogen-norethindrone treatment on total cholesterol level, high-density lipoprotein cholesterol level, blood pressure, and body mass index was investigated in 74 postmenopausal women in a doubleblind, randomized trial. Blood pressure and body mass index did not change throughout the study. We demonstrated a decrease (11%) in serum cholesterol level after 1 year of treatment with estrogen-norethindrone. When this treatment was combined with cholecalciferol, a similar decrease (13%) was observed. The hypocholesterolemic effect was correlated to body mass index in a way that indicated the most pronounced decrease in lean women. The high-density lipoprotein cholesterol/total cholesterol fraction increased by 45% after 1 year of estrogen-norethindrone treatment, while an increase of 25% after 1 year was seen when cholecalciferol was added to the treatment. The latter increase was not different from a similar increase in the placebo group. The possible dyslipidemic effect of cholecalciferol, along with the risk of hypercalcemia, emphasizes the caution necessary in cholecalciferol treatment.
