Background: Cardiovascular risk is increased in transgender persons using gender-affirming hormone therapy. To gain insight into the mechanism by which sex hormones affect cardiovascular risk in transgender persons, we investigated the effect of hormone therapy on markers of inflammation and hemostasis. Methods: In this exploratory study, 48...

Background: The development of global tests for the fibrinolytic capacity in blood is hampered by the low base-line fibrinolytic activity in blood, by the involvement of both plasmatic components and blood cells in the fibrinolytic system and by the loss of fibrinolytic activity as a result of the action of plasminogen activator inhibitor-1 (PAI...

Epidemiological studies have shown that hormone therapy (HT) increases the risk of venous thromboembolism in post menopausal women. The mechanism of this increased risk is unknown; however, activation of the haemostatic system is known to contribute to the pathogenesis of venous thromboembolism. In post-menopausal women the estrogen /progestogen...

Murine blood coagulation factors and function are quite similar to those of humans. Because of this similarity and the adaptability of mice to genetic manipulation, murine coagulation factors and inhibitors have been extensively studied. These studies have provided significant insights into human hemostasis. They have also provided useful...

Since activation of the haemostatic system is an important feature of the wound healing response triggered by arterial injury, variations in genes involved in thrombus formation may play a role in restenosis after percutaneous coronary interventions (PCI). Therefore, our aim was to examine the relationship between polymorphisms that are known to...

Differences in genetic influence on death from CHD between males and females have been reported. Haemostatic factors have consistently been associated with risk for coronary heart disease (CHD), but sex differences in genetic architecture have not been studied. This study in middle-aged twins investigates whether there are sex differences in...

Objective: This study aimed to compare the effects on hemostasis variables of a contraceptive vaginal ring with those of an oral contraceptive. Study design: Twenty-three and 22 healthy premenopausal women were randomized to the contraceptive vaginal ring (150 μg Nestorone and 15 μg ethinyl estradiol) or Stediril 30 during 3 cycles. Analysis of...

Purpose: In this open-label, randomized study, we assessed the effects on hemostasis of two combined oral contraceptives containing drospirenone (DRSP) as progestogen component. Methods: Three milligrams of DRSP, a progestogen with antimineralocorticoid activity, was combined with either 30 or 20 μg ethinyl estradiol (EE) (DRSP/30EE; DRSP/20EE)...

Background: Administration of oral contraceptives (OCs) has profound effects on the plasma levels of haemostasis and inflammation variables, resulting in an increased thrombosis risk. Individuals show large differences in the response of these variables to OCs. Polymorphism in the estrogen receptor-1 (ER1) gene may explain part of this inter...

The comparability of test results for protein S between laboratories is hampered by a high inter-laboratory variability. The effect of the use and type of common reference plasma on the inter-laboratory variability of the total and free protein S measurement was evaluated. The results of 10 plasma samples measured against a centrally distributed...

In a previous study, a between-operator variability (CVOBETWEEN) of 9.6% and 15.0% was observed for total protein S antigen assays in 11 laboratories using a frozen or lyophilized reference plasma, respectively, and the need to standardize the use of lyophilized reference plasma was identified. The aim of the present study was to identify...

Objective - The angiogenesis inhibitor SU5416 is a potent inhibitor of vascular endothelial growth factor (VEGF) receptor-1 and -2. VEGF may be involved in hemostasis by altering the hemostatic properties of endothelial cells. We analyzed the effects of SU5416 on the coagulation cascade and the vessel wall in patients with advanced cancer....

To characterize the extent of activation of the hemostatic system and to detect local alterations which may favour thrombus formation we obtained samples from the right atrium (RA) and left ventricle (LV) of 60 stable angina patients (mean age 59 years, M/F: 49/11) during the cardiac catheterization procedure. None of the patients had a recent...

OBJECTIVE - The high risk for cardiovascular disease in IDDM patients with nephropathy may be mediated by abnormal function of the vascular wall. We investigated whether heparin was able to modulate markers of vascular wall and hemostatic function in patients with incipient nephropathy. RESEARCH DESIGN AND METHODS - Thirty-five IDDM patients...

Combined oral contraceptives (COCs) have effects on a large number of haemostasis variables. We have summarised literature data on effects of COCs containing 30-35 μg ethinyl estradiol for the third generation of progestogens (PGs): desogestrel, gestodene and norgestimate. It is concluded that about 15 variables show a shift in distribution of...

A high fat intake has been associated with the high prevalence of coronary heart disease (CHD) in most Western countries. Consumption of reduced-fat products might reduce fat intake and beneficially affect markers of CHD risk. Therefore, the effects of 6 months of realistic consumption of reduced-fat products on energy and fat intake,...
