Differential Effects of Estradiol and Progesterone on Cardiovascular Risk Factors in Postmenopausal Women.


ABSTRACT: Controlled, blinded studies of sex-hormone replacement in postmenopausal women using natural estradiol (E2) and native progesterone (P) are few.To delineate the effect of E2 alone or with P on lipids and inflammatory markers.A placebo-controlled, double-masked, prospectively randomized study of 40 healthy, postmenopausal volunteers assigned to four treatment groups: placebo, intramuscular E2, and/or micronized oral P for 23 (±2) days.Treatment with E2 alone compared with placebo lowered total cholesterol (TC; P = 0.006), non-high-density lipoprotein cholesterol (nonHDL-C; P = 0.004), low-density lipoprotein cholesterol (LDL-C; P = 0.012), and apolipoprotein B (Apo B; P = 0.02) levels, and raised HDL-C levels (P = 0.03 vs the 3 other groups). Conversely, addition of P to E2 reduced HDL-C levels (P = 0.015). Triglyceride concentrations manifested no effect on E2 or P. High-sensitivity C-reactive protein (hsCRP) level was highest in women with E2 and P replacement (P = 0.018 vs placebo). Leptin and IL-6 concentrations did not vary. P treatment decreased adiponectin levels (P = 0.019). Serum E2 levels correlated linearly with TC, LDL-C, nonHDL-C, Apo B (all negatively), and SHBG (positively) concentrations. P level correlated negatively with TC (P = 0.029), HDL-C (P = 0.002), and adiponectin (P = 0.002) levels.In this study, there were individual and interactive effects of E2 and P on key lipids in postmenopausal individuals.
