OBJECTIVE To determine the effects of tibolone and continuous combined HRT (ccHRT) on parameters in the clotting cascade. DESIGN Randomized, double-blind study. SETTING Hemostasis unit of a university hospital clinic in Germany. PATIENT(S) Sixty healthy postmenopausal women. INTERVENTION(S) Twenty-nine subjects were treated with tibolone (2.5 mg/d)(More)
In a double-blind, controlled, randomized, four-arm, bicentric clinical study, the effect of four oral contraceptives (OCs) on various hormone parameters and serum-binding globulins was investigated. Four groups with 25 volunteers each (18-35 years of age) were treated for six cycles with monophasic combinations containing 21 tablets with either 30 microg(More)
The serum concentrations of 3-ketodesogestrel (KDG) and gestodene have been measured in 30 and 31 women respectively who took low dose oral contraceptives containing 30 micrograms ethinylestradiol together with either 150 micrograms desogestrel or 75 micrograms gestodene for 6 months. On days 1, 10 and 21 of the first third and sixth treatment cycles blood(More)
Androgen deficiency is associated with an increased incidence of cardiovascular disease. There is evidence that thromboembolic disease as well as myocardial ifarction in hypogonadic males are mediated by low baseline fibrinolytic activity. Hypogonadism in males is associated with an enhancement of fibrinolytic inhibition via increased synthesis of the(More)
The effect of progestin-only therapy on the haemostatic system has mainly been studied in premenopausal women. Although these studies are difficult to compare, most authors agree that there is no consistent pattern of effects on haemostasis. Oestrogen-progestin combinations have been extensively studied in pre- (combined oral contraceptives) and(More)
This is the first double-blind, controlled, randomized study comparing the effect of different estrogen components in oral contraceptives (OCs) on hemostasis variables. Four groups of 25 women each were treated for six cycles with monophasic combinations containing 21 tablets with either 30 microg ethinylestradiol (EE) + 2 mg dienogest (DNG) (30EE/DNG), 20(More)
Despite being an unprecedented departure from normal physiology, the combined oral contraceptive is not only highly effective, but it also has a remarkably good safety record. Concerns over safety persist, though, particularly with regard to venous thromboembolism (VTE), stroke and myocardial infarction (MI). Epidemiological studies consistently show an(More)
The plasmatic parameters of coagulatory and fibrinolytic activity were studied in 15 patients with biopsy-proven endometriosis treated with leuprorelin acetate for 6 months. Bleeding time remained constant, indicating the absence of increased bleeding tendencies. The activity of the main inhibitor of the fibrinolytic response, plasminogen activator(More)
Some observational studies have found a difference in the risk of nonfatal venous thromboembolism (VTE) with low-dose, oral contraceptives (OCs) containing desogestrel (DSG) or gestodene (GSD) and those containing levonorgestrel (LNG). However, this does not agree with current pathophysiological concepts. This review compares all 17 comparative studies on(More)
