AIM To determine the frequency of inherited and acquired prothrombotic risk factors in children with arterial ischemic stroke (AIS) and transient ischemic attacks (TIA) in Croatia. METHODS We investigated 14 prothrombotic risk factors using blood samples from 124 children with AIS or TIA and 42 healthy children. Prothrombotic risk factors were classified into five groups: natural coagulation ...

Septic shock and multiple organ failure may be associated with coagulation activation, disseminated fibrin formation, and consumption of coagulation inhibitors such as antithrombin 111. We have evaluated prospectively coagulation measurements in patients with severe chemotherapy-induced neutropenia. This group of patients was chosen because of their high risk of developing severe septic cornpli...

Anticoagulant drugs are the most frequently hospital-prescribed compounds in many countries and are used with the intention to prevent and treat venous and arterial thromboembolism. Because of side effects and the necessity of dose adjustment of unfractionated heparins and coumarins, low-molecular-weight heparins, heparinoids, and direct systemically applied thrombin inhibitors were developed. ...

We describe a family with an autosomal dominant disorder characterized by severe trauma- and surgery-related bleeding. The proband, who experienced life-threatening bleeding during a routine operation, had normal clotting times, but markedly reduced prothrombin consumption. Plasma levels of all coagulation factors and of the main coagulation inhibitors were normal. Thrombin generation at low tr...

Thrombosis is one of the major complications of polycythemia vera. Seventeen patients with polycythemia vera in good hematologic control were evaluated for abnormalities of the coagulation system. Activation of the intrinsic coagulation cascade was suggested by low levels of factor XII, prekallikrein, and kallikrein inhibitors in 12 of 17 patients. The group also demonstrated a significant inc...

Protein Z (PZ)-dependent protease inhibitor (ZPI) and antithrombin (AT) are two physiological serpin inhibitors involved in the regulation of proteolytic activities of the blood coagulation cascade. ZPI has restricted protease specificity capable of inhibiting factors Xa (FXa) and XIa (FXIa) but exhibiting no reactivity with other coagulation proteases. Unlike ZPI, AT is a general inhibitor of ...

Introduction Factor VIIa along with tissue factor starts whole coagulation process, so factor VIIa is acting as attractive target for anticoagulant drug design. The inhibition of factor VIIa can result in inhibition of coagulation in the early stages. The factor VIIa inhibitors can act more potent antithrombotic than factor Xa inhibitors. Variety of factor VIIa inhibitors are reported by the va...

OBJECTIVE Serine protease inhibitors (serpin) play a central role in various pathological processes including coagulation, fibrinolysis, malignancy, and inflammation. Inhibition of serpins may prove therapeutic. As yet, however, only very few small molecule serpin inhibitors have been reported. For the first time, we apply a new approach of virtual screening to discover novel, orally active, sm...

One of the last remaining clinical hurdles in the treatment of people with hemophilia is the development of inhibitors. Alloantibodies or autoantibodies directed at coagulation factors render the infusion of coagulation factor concentrates ineffective, and alternative means must be used to achieve hemostasis. Recombinant factor VIIa (rFVIIa) was developed to control bleeding episodes in hemophi...
