t-PA depleted citrated plasma was used to prepare standards of different molecular forms of plasminogen activator inhibitor 1 (PAI-1). These standards were used to evaluate the specificity of two new PAI-1 antigen assays: the TintElize PAI-1 antigen assay (cat. no. 210221) and the Innotest PAI-1. Differences in specificity were apparent: the...

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...

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...

A disturbed hypothalamus-pituitary-adrenal gland axis and alterations at the immune system level have been observed in patients with chronic fatigue syndrome (CFS). Glucocorticoids are known to modulate T cell responses; therefore, purified CD4 T cells from CFS patients were studied to determine whether they have an altered sensitivity to...

In view of reported associations between increased bleeding tendency and systemically decreased alpha 2-antiplasmin in patients with systemic amyloid deposition we studied alpha 2-antiplasmin, fibrinogen, C-reactive protein and blood levels of locally produced endothelial hemostasis factors in the acute and quiescent phase in 16 patients with...

Objective: We studied the association of plasma concentrations of tissuetype plasminogen activator (t-PA) and the, until now single documented polymorphism of the t-PA gene, with degree of atherosclerosis and the prevalence of myocardial infarction. Design: Cross-sectional, population-based case control study. Setting: A district of Rotterdam,...

Apart from tissue-type plasminogen activator (t-PA) and urokinase-type plasminogen activator (u-PA), a third PA appears to occur in human plasma. Its activity is initiated when appropriate triggers of the contact system are added, and the activation depends on the presence of factor XII and prekallikrein in plasma. The activity of this, so...

Purpose: The aim of this study was to compare effects of the transdermal contraceptive patch, a desogestrel/ethinyl estradiol (EE)-containing, monophasic combination oral contraceptive (COC) and a levonorgestrel/EE-containing, triphasic COC on hemostasis variables. Study Design: This was a randomized, open-label study of 104 young women who...

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: Pentosan polysulphate sodium (PPS), a heparin-like drug, is supposed to be orally applicable. The objective of the present study was to assess the oral bioavailability of PPS. However, since specific assays for PPS do not exist, this was done by using primary and secondary effect parameters. Methods: The study was carried out using a...

Plasminogen activator inhibitor (PAI) activity, an important regulator within the fibrinolytic system, has been shown to be a risk indicator for venous and arterial thrombosis. The present study aimed to test the effects of exercise training on PAI activity, and to link possible changes in PAI activity to changes in cardiovascular fitness, body...

This study concerns a case of congenital homozygous deficiency in ??2-antiplasmin associated with a severe hemorrhagic diathesis. Heterozygous family members also show a mild bleeding tendency. The propositus is a 17-yr-old male born of white parents and showing a severe hemorrhagic diathesis characterized by spontaneous bleeding in the joints...

The genetic basis of cardiovascular disease (CVD) with its complex etiology is still largely elusive. Plasma levels of lipids and apolipoproteins are among the major quantitative risk factors for CVD and are well-established intermediate traits that may be more accessible to genetic dissection than clinical CVD end points. Chromosome 19 harbors...

Elevated plasma fibrinogen levels represent an increased risk for cardiovascular diseased, but the mechanism explaining this association is still not clear. Genetic differences may play a role, because it has been shown that individuals who carry the rare alleles of polymorphisms in the genes for the Bβ-chain (Bcl I and G/A 455) and the Aα-chain...

Plasma levels of lipoprotein(a) - Lp(a) - are associated with cardiovascular risk (Danesh et al., 2000) and were long believed to be influenced by the LPA locus on chromosome 6q27 only. However, a recent report of Broeckel et al. (2002) suggested the presence of a second quantitative trait locus on chromosome 1 influencing Lp(a) levels. Using a...

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...
