Introduction. The exclusion of deep venous thrombosis (DVT) by pre-test probability (PTP) and D-dimer in the elderly is safe, but has a low specificity. There is increasing interest in the diagnostic role of thrombin generation in patients with thrombosis. We evaluated the value of thrombin generation in the exclusion of DVT, especially in...

In 2004 the Netherlands Twin Register (NTR) started a large scale biological sample collection in twin families to create a resource for genetic studies on health, lifestyle and personality. Between January 2004 and July 2008, adult participants from NTR research projects were invited into the study. During a home visit between 7:00 and 10:00 am...

The PERTINENT study measured biomarkers of atherosclerosis and thrombosis in a stable coronary artery disease population from EUROPA receiving ACE inhibition with perindopril 8 mg/day or placebo. Biomarkers of inflammation, C-reactive protein (CRP), fibrinogen, and tumor necrosis factor-alpha (TNF-α), and a biomarker of thrombosis, d-dimer, were...

To identify the genomic regions that confer risk and protection for major depressive disorder (MDD) in humans, large-scale studies are needed. Such studies should collect multiple phenotypes, DNA, and ideally, biological material that allows gene expression analysis, transcriptomic, proteomic, and metabolomic studies. In this paper, we briefly...

Ischemic stroke is associated with leucocyte activation. Activated leucocytes release elastase, an enzyme that can degrade fibrinogen. Fibrinogen elastase degradation products (FgEDP) may serve as a specific marker of elastase proteolytic activity. In a case-control study of 111 ischemic stroke patients and 119 controls, significantly higher...

Objective: To review the effects of non-oral administration of postmenopausal hormone therapy (HT) on risk markers for atherosclerotic and venous thromboembolic disease.Non-oral postmenopausal HT appears not to increase venous thromboembolic risk, whereas the effect on coronary heart disease risk is less clear. Design: Systematic review of...

Increased plasma factor VII coagulant activity (FVII:C) has been associated with the risk of ischemic heart disease (IHD). Differences in plasma FVII:C among individuals are associated with three common polymorphisms in the FVII gene. Therefore, we investigated FVII polymorphisms in four populations that differ in their risk of developing...

Elevated plasma fibrinogen levels are associated with an increased risk for cardiac events. Ticlopidine is a drug that inhibits the ADP-induced aggregation of blood platelets and it also has been described that ticlopidine can decrease the plasma fibrinogen level in patients with vascular diseases. The mechanism of this decrease has not yet been...

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,...

The use of Stabilyte® plasma in the Coaliza® t-PA, Coaliza® PAI-1 and Enzygnost® PAP micro was evaluated. For PAI-1 antigen no, for t-PA antigen only small differences were observed between measurements in citrate and Stabilyte® plasma. For PAP-complexes significant lower (72%) results were obtained when Stabilyte® plasma was applied. This is...

Recently, two molecular weight forms of Histidine-rich Glycoprotein have been described which explain 59% of the variation in plasma HRG levels. Here, we demonstrate that this can partly be ascribed to a difference in specificity of the immuno assay for HRG towards the two alleles of the polymorphism.

Raised plasma PAI-1 and t-PA antigen levels are known risk factors for acute coronary events. It is not known whether these factors are related to coronary thrombosis or to a possible atherosclerotic background. Both factors show a marked circadian variation in blood. To assess the effect of atherosclerosis on the fibrinolytic balance, we...

Test procedures of several commercially available functional test kits for α2-antiplasmin were investigated. The importance of the plasmin concentration, the amount of plasma used in the test and the preincubation time for a specific test for the determination of α2-antiplasmin were discussed. A Specific Plasmin Inhibition Test (SPIT) suitable...

Background: Although a major role of coronary thrombosis in the pathogenesis of unstable angina has been demonstrated, the results of a series of studies have suggested that activation of the hemostatic system may not be confined to ischemic episodes. The purpose of this study was to investigate the temporal relation between ischemic episodes...

A pedigree-based maximum likelihood method developed by Lange et al. (12) was used to study the contribution of a newly defined di-allelic polymorphism in histidine-rich glycoprotein (HRG) to the plasma levels of HRG. In four families (n = 99) and 20 volunteers we found a heritability of 70%, an age effect of 3% and an effect of individual...
