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...

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...

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...

The mechanism of air travel-related venous thrombosis is unclear. Although immobility plays a pivotal role, other factors such as fluid loss may contribute. We investigated whether fluid loss occurred more in individuals with coagulation activation after air travel than in subjects without. As a secondary aim, we investigated whether fluid loss...

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 - Besides having a key role in fibrinolysis, the plasminogen system has been implicated in cell migration and angiogenesis. A common mechanism is the binding of plasminogen to carboxy-terminal lysine residues in partially degraded fibrin or on cellular surfaces. Here we examined the involvement of thrombin activatable fibrinolysis...

The numerical test results of different D-dimer assays vary widely. Because of the complexity of the analyte of target as well as the variability in specificity of different D-dimer assays, only harmonisation of the test results seems to be feasible. The use of a single conversion factor does not take into account for several methods the lack of...

Monoclonal antibody (mAb) III-3b binds D-dimer with Kd = 1.4 × 10-10 M without cross-reaction with fibrin(ogen). The epitope for this mAb is in Bβ134-190, presumably in Bβ155-160. The latter site is buried in the coiled coil structure of fibrin(ogen) but it is exposed as a neoantigenic determinant in D-dimer upon plasmic lysis of fibrin. mAb III...

The present study examined the influence of ingesting a moderate dose of alcohol on plasminogen activator activity (t-PA), plasma fibrinogen (Fb), total degradation products (TDP) and the degradation products of fibrin (FbDP) and fibrinogen (FgDP) at rest and in response to exercise. Eleven male subjects performed two separate experimental...

The classical clinical signs of deep vein thrombosis (DVT) are unspecific and may be found in several other conditions besides DVT. Therefore, patients suspicious of DVT are subjected to elaborate invasive or noninvasive evidence-based procedures that actually confirm DVT in only 20% to 30% of patients in this setting. However, simple laboratory...

The term 'D-dimer assay' suggests, that these assays report the concentrations of the end-stage degradation product of crosslinked fibrin. This hardly occurs in patients. Degradation products of crosslinked fibrin rather occur with a wide range of molecular weights, and comprise various numbers of the D-dimer motif. Moreover, the numerical...

Upon stimulation, polymorphonuclear leucocytes (PMNs) release potent serine proteases, i.e. elastase, cathepsin C and proteinase 3, which contribute to the degradation of tissue and plasma components. Here, we describe the development of a plasma test to assess PMN-mediated fibrinogenolysis as a biochemical marker for actual PMN-derived...

A high intake of β-carotene has been associated with a decreased risk for cardiovascular disease. To evaluate whether β-carotene may exert a protective effect through an impact on haemostasis a randomized, placebo-controlled trial was conducted in male smokers (n = 149) using 20 mg/day β-carotene for 14 weeks. For comparisons, haemostatic...

Fibrinolytic parameters and von Willebrand factor (vWF) antigen were measured in the plasma of 10 patients with hemolytic uremic syndrome (HUS). Samples were taken at presentation and again 2 wk later, before and after infusion of 1-desamino-8-arginine vasopressin. Compared with the plasma values of healthy control children, levels of tissue...

Increased plasma levels of soluble fibrin are considered as molecular markers of an impending thrombotic event. Several methods to assess soluble fibrin have been in existence for many years. Most of those methods are nonspecific, semiquantitative or too laborious to be used in clinical practice. More recent methods are quantitative and...

Each of three distinct, concentric layers of human arterial thrombi, was analysed immunochemically for the plasminogen and fibrin content, and for the ex vivo susceptibility to thrombolysis by various thrombolytic agents in a saline or plasma milieu. The age of the thrombus layer determined: (a) the plasminogen content; (b) the fibrin content,...

Several investigators have reported that tumor necrosis factor (TNF) can alter the production of plasminogen activator type-1 (PAI-1) and plasminogen activators (PAs) by endothelial cells in vitro. We have examined the in vivo effects of recombinant human TNF administration on fibrinolysis as assessed by parameters in plasma during a 24-hour...

The effect of purified human activated protein C (APC) and protein S on fibrinolysis was studied by using an in vitro blood clot lysis technique. Blood clots were formed from citrated blood (supplemented with 125I-fibrinogen) by adding thrombin and Ca2+-ions; lysis of the clots was achieved by adding tissue-type plasminogen activator. The...

Balb/c mice were immunized with a mixture of fibrin degradation products (XDPs) prepared by complete lysis of a human bloot clot by tissue-type plasminogen activator and purified by immunoaffinity chromatography. Spleen cells of the mice were fused with P3 x 63 Ag 8653 myeloma cells. A clone (FDP 14) was selected that produces monoclonal...

Spleen cells of BALB/c mice, immunized with fragments Y of normal human fibrinogen, were fused with P3 x 63 Ag 8653 myeloma cells. A clone was found which produces monoclonal antibodies (Mab-Y18) of the IgM?? type. Mab-Y18 is immunoreactive with normal human fibrinogen, and its fragments X, Y, N-terminal disulphide knot, A??-chain, and A??...
