Background. Hormone replacement therapy (HRT) has been known to have beneficial effects on various atherosclerotic parameters in the general population of post-menopausal women. To evaluate the effects of HRT on those factors in end-stage renal disease (ESRD) patients, we evaluated the changes of lipid profile, coagulation and fibrinolysis markers, and plasma homocysteine levels after treatment.
Methods. Sixty-five post-menopausal women on maintenance haemodialysis were randomly assigned to either an HRT group (n=33) or a control group (n=32). Median age (range) and duration of haemodialysis (range) were 57 years (40–73) and 42 months (6–150) in the HRT group and 61 years (44–78) and 54 months (8–174) in the control group respectively. Oral conjugated oestrogen (0.625 mg) combined with medroxyprogesterone acetate (2.5 mg) was given daily for 12 weeks to the HRT group. Total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), lipoprotein (a) (Lp(a)), fibrinogen, plasminogen activator type 1 antigen (PAI-1), tissue plasminogen antigen (t-PA), von Willebrand factor (vWF), and plasma total homocysteine (tHcy) were measured before and 12 weeks after the start of the study in both groups.
Results. There was no difference in baseline values between the control and HRT groups. At 12 weeks, HRT increased HDL-C by 12% (P<0.01) and TG by 20% (P<0.01). HRT decreased LDL-C by 9% (P<0.01), and Lp(a) by 36% (P<0.01). PAI-1 and t-PA concentrations were also reduced by 21% (P<0.01) and 9% (P<0.05) respectively. The mean values of TC, fibrinogen, vWF, and tHcy levels did not change significantly after HRT.
Conclusions. The above results suggest that HRT has favourable effects on atherosclerosis risk parameters in post-menopausal women with ESRD as in the general population of post-menopausal women.
