Abstract: BACKGROUND/AIM:The aim of this prospective controlled study was to compare the effects of two therapies for menopause on factor VII (FVII) and hemostatic variables. METHODS: Postmenopausal women were assigned to receive one of the following treatments: transdermal estradiol (TTS E2; 50 microg) combined in a continuous sequential regimen with oral medroxyprogesterone acetate (MPA; 10 mg/day for 12 days) (group A; n = 20), tibolone (2.5 mg/day) (group B; n = 21) or placebo (group C; n = 19). Sixty women completed the 1-year treatment and underwent follow-up examinations after 3, 6 and 12 months. RESULTS: TTS E2/MPA induced various changes in procoagulatory factors. At 12 months, fibrinogen, activated FVII (FVIIa) and coagulative FVII (FVIIc) had increased by 10.7, 12.9 and 3.7%, respectively. Among the fibrinolytic factors, plasminogen and alpha2-antiplasmin increased by 11.3 and 7.2%, respectively. Lipoprotein(a) [Lp(a)] and antithrombin III (ATIII) did not show any significant variation. Tibolone induced some changes toward a more homogeneous antithrombotic profile. Fibrinogen, FVIIa and FVIIc decreased significantly by 7.5, 8.1 and 21.3%, respectively. Plasminogen increased (by 11.8%) and Lp(a) decreased (by 28.4%). ATIII was unchanged with tibolone therapy. CONCLUSION: Our results show that tibolone induces a significant reduction in FVIIc and Lp(a) and a greater enhancement of factors promoting fibrinolysis than the TTS
