[Relationship between sex hormone levels and blood lipids/immunity in perimenopausal women].
To investigate the relationship between sex hormone levels and blood lipids/immunity and to evaluate the therapeutical effects of nylestriol, 96 women without coronary heart disease(CHD) were studied during their perimenopausal period. The estimation of serum biochemical components included serum 17 beta-estradiol(E2), testosterone(T), total cholesterol(TC), triglyceride (TC), high density lipoprotein cholesterol(HDL-C), low density protein cholesterol(LDL-C), apolipoprotein A-I(ApoAI), apolipoprotein B(ApoB), lipoprotein (a)[Lp(a)], immunoglobulin G(IgG), and IgG antibody against cardiolipin(ACAIgG). Thirty-six postmenopausal volunteers were divided into two groups and randomized to treat with either 2 mg nylestriol or placebo. In postmenopausal women, serum levels of E2, E2/T, HDL, and ApoAI decreased, while those of T, TC, TG, LDL, ApoB, Lp(a), IgG, and ACAIgG increased. Serum level of E2 was positively correlated to HDL-C and negatively correlated to TC, ApoB, LDL, IgG, and ACAIgG. Serum level of T was positively correlated to LDL, IgG, and ACAIgG and negatively correlated to HDL. In the nylestriol group, as compared with the results before treatment, serum levels of TG, TC, LDL, IgG, and ACAIgG decreased and that of HDL-C increased after treatment. We conclude that estradiol is a protective factor of CHD, whereas testerone is a dangerous factor. After menopause, the imbalance of the estradiol/testosterone ratio increases the incidence of CHD. Nylestriol is an effective substitute for estradiol to prevent CHD in post menopausal women.
