The effects of two fixed hormonal replacement therapy protocols on blood lipid profile.

Hormonal Replacement Therapy (HRT) is known to be accompanied by changes in blood lipid profile. The present prospective cohort study compared the blood lipid profile of healthy postmenopausal women treated with either (a) a preparation containing a fixed regimen of estradiol, estriol and norethisterone acetate (EENA, marketed under the trade name Trisequens); (b) a fixed protocol of conjugated equine estrogen and medroxyprogesterone acetate (CEEMPA, marketed under the trade name Premaril Plus); or with (c) a concurrent group which underwent no treatment. Blood lipid profiles (total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C), and triglycerides (TG)) were performed at the beginning of the study and at 3-month intervals, for 9 months.
