Assessment of hypercoagulability markers and lipid levels in postmenopausal women undergoing either oral or transdermal hormone replacement therapy.

Abstract

BACKGROUND:

This study investigated the effect of either oral or transdermal hormone replacement therapy (HRT) on haemostatic, fibrinolytic and lipid profiles in a group of Brazilian women 3 months after beginning treatment by comparing these results with those obtained immediately before HRT.

METHODS:

Plasma levels of TAT, DDi, F1+2, PC, PS, AT, PAI-1 and serum lipids were determined in blood samples collected from 24 women undergoing oral HRT and from 11 women undergoing transdermal HRT.

RESULTS:

Significant increases in DDi and F1+2 plasma levels were observed after 3 months of oral HRT, while PS levels decreased. After transdermal HRT, a significant decrease was observed only for AT levels.

CONCLUSION:

After 3 months of oral HRT and in the absence of major genetic and acquired risk factors, women displayed a predisposition for activation of blood coagulation, and an increased activity of the fibrinolytic system. Oral HRT seemed to be more effective in predisposing haemostatic changes as compared to transdermal.
