BACKGROUND Fibrin fragment D-dimer, one of several peptides produced when crosslinked fibrin is degraded by plasmin, is the most widely used clinical marker of activated blood coagulation. To identity genetic loci influencing D-dimer levels, we performed the first large-scale, genome-wide association search. METHODS AND RESULTS A genome-wide investigation of the genomic correlates of plasma D...
The D-dimer antigen is a unique marker of fibrin degradation that is formed by the sequential action of 3 enzymes: thrombin, factor XIIIa, and plasmin. First, thrombin cleaves fibrinogen producing fibrin monomers, which polymerize and serve as a template for factor XIIIa and plasmin formation. Second, thrombin activates plasma factor XIII bound to fibrin polymers to produce the active transglut...
Background and Objective: Multiple Sclerosis (MS) is a neurological disorder that can restrict individual's ability to carry on their activities. The[J1] aim of this study was to examine the effects of combined exercise training on serum Fibrin D-Dimer (FDD) and interleukin-6 in female multiple sclerosis patients with different levels of disability. Materials and Methods: 96 female patients ...
We evaluated 50 consecutive patients with acute ischemic stroke to assess the prevalence of systemic infection preceding the neurological event. We analyzed the immunohematologic characteristics of patients with and without signs and/or symptoms of a preceding infectious process. Patients were examined less than or equal to 7 days after cerebral infarction and evaluated for fibrinogen, anticard...
Plasma D-dimer concentration rises more than 100-fold during acute deep vein thrombosis, but there are no prospective data concerning D-dimer as a risk factor for incident venous thrombosis in a general population. Incident venous thrombosis was ascertained in 2 prospective observational studies, the Atherosclerosis Risk in Communities Study and the Cardiovascular Health Study. Of 21 690 partic...
To clarify the influence of neutral dialysate (ND) on peritoneum, we examined changes in peritoneal permeability and in various markers of the coagulation and fibrinolytic system in effluent and the correlations between peritoneal permeability and those markers in peritoneal dialysis (PD) patients using ND. We evaluated 14 patients (8 men, 6 women; mean age: 58.6 +/- 12.0 years) who started PD ...
Fibrin is the main thrombus component. Its production being definitely lower in in-patients than in outpatients. is followed by activation of the fibrinolytic system, resulting in plasmin generation and subsequent fibrin lysis (Figure 1). Dissolution of crosslinked fibrin leads to formation of specific degradation products, includMethods for measuring DD in blood ing D-dimer (DD),1 which can be...
Factor XIII-cross-linked fragment D (double-D) from human fibrin was crystallized in the presence of two different peptide ligands and the X-ray structure determined at 2.3 A. The peptide Gly-Pro-Arg-Pro-amide, which is an analogue of the knob exposed by the thrombin-catalyzed removal of fibrinopeptide A, was found to reside in the gamma-chain holes, and the peptide Gly-His-Arg-Pro-amide, which...
Fragment D has been isolated as an apparently single molecular weight species (molecular weight about 100,000) from plasmin digests of humman fibrinogen, using a combination of affinity chromatography on insolubilized "fibrin monomer" and gel filtration. This fragment consists of three chains with molecular weights of 15,000 (Dbeta), 42,500 (Dgamma1) or 39,500 (Dgamma2), and 14,000 (Dalpha) hel...
OBJECTIVE To investigate the relation between intracardiac thrombus and blood coagulability in patients with mitral stenosis. DESIGN Prospective study. Cross sectional echocardiography and plasma concentrations of the D-dimer fragment of fibrin were used concurrently to detect intracardiac thrombus in patients with mitral stenosis. SETTING Department of Medicine, National Cardiovascular Cen...
