A family with a peculiar defect of factor VII is described. The propositi, a brother and sister, were born of a nonconsanguineous marriage and presented a mild to moderate bleeding tendency since childhood (epistaxis, excessive bleeding after tooth extraction). The coagulation pattern was characterized by a mildly prolonged prothrombin time, normal partial thromboplastin time, and normal Stypve...
Recombinant activated coagulation factor VII (rFVIIa) is known to be effective in the management of acquired deficiencies of factor VII and platelet function defects. But recently, rFVIIa has been successfully used to treat ongoing bleeding in disseminated intravascular coagulopathy (DIC) condition. The patient reported here was suspected to be suffering from toxic hepatitis on admission. After...
Aim: Normal pregnancy is associated with haemostatic changes which have been linked to a complex physiological adaptation but these changes return to that of non-pregnant state at about 4 weeks of post-delivery. This study was undertaken to monitor the haemostatic changes during pregnancy and puerperium in North-Western Nigeria. Materials and methods: Ten pregnant women, aged 17-40 years were m...
Coagulation factor VII (FVII) is a vitamin K dependent glycoprotein of the extrinsic pathway and initiates coagulation by binding to tissue factor. Activated prothrombin-complex concentrate ([APCC] FEIBA), an activated prothrombin complex concentrate that is plasma-derived, has also been demonstrated to bypass the need for FVIII or factor IX, resulting in hemostasis. Both APCC and recombinant f...
Factor VII activating protease (FSAP) is a circulating serine protease with high homology to fibrinolytic enzymes. A role in the regulation of coagulation and fibrinolysis is suspected based on in vitro studies demonstrating activation of FVII or pro-urokinase plasminogen activator (uPA). However, considering the paucity of any studies in animal models or any correlative studies in humans the r...
Factor VII circulates as a single chain inactive zymogen (10 nmol/L) and a trace ( approximately 10-100 pmol/L) circulates as the 2-chain form, factor VIIa. Factor VII and factor VIIa were studied in a coagulation model using plasma concentrations of purified coagulation factors with reactions initiated with relipidated tissue factor (TF). Factor VII (10 nmol/L) extended the lag phase of thromb...
