Factor VII deficiency

American Journal of Hematology, 1981
AbstractThis report describes three patients with factor (F) VII deficiency: two adult siblings and an unrelated 5½‐month‐old child who succumbed after several central nervous system (CNS) hemorrhages. This event prompted a review of the literature concerning the incidence and characteristics of intracranial hemorrhage in congenital F VII deficiency.Of

Molecular Variant of Factor VII [PDF]

Thrombosis and Haemostasis, 1976
SummaryTwo patients with severe factor VII deficiency appeared to be different with respect to the presence of inactive factor VH-like material in their plasma.The inactive material, demonstrated in one patient’s plasma and adsorbable onto BaSO4, inhibits the thrombotest-system and is capable of neutralizing a heterologous antibody against factor VII ...

Factor VII Survival Studies in Factor VII Padua Abnormality

Acta Haematologica, 1980
Two patients with factor VII Padua abnormality were studied during prophylactic administration of factor VII concentrates for tooth extractions. The amounts administered were 15.8 and 17.2 units/kg body weight in 30 and 20 min, respectively. The end infusion factor VII activity levels were 55 and 64%, respectively.

Factor VII activity and antigen in a patient with abnormal factor VII

Clinical & Laboratory Haematology, 1988
A patient with abnormal factor VII, which showed different activity when thromboplastin from different sources was used, is reported. The propositus, who was first seen at routine health examination 1 month after delivery, was a girl with no complaints of bleeding.

The Activation of Factor VII [PDF]

Thrombosis and Haemostasis, 1975
Native factor VII (F. VIIn) can be activated by thromboplastin or by the kallikrein-system. This gives rise to two different forms of activated factor VII. We thus discern Factor VIIn, cold activated factor VII (C.P.A-F. VIIa) and thromboplastin activated factor VII (T-F. VIIa).We developed one- and two-stage assays that distinguish between these forms

Clinical phenotypes and factor VII genotype in congenital factor VII deficiency

Thrombosis and Haemostasis, 2005
SummaryTo investigate the relationship between clinical phenotype, clotting activity (FVIIc) and FVII genotype, a multi-center study of factor VII (FVII) congenital deficiency with centralized genotyping and specific functional assays was carried out. FVII mutations characterized in patients (n=313) were extremely heterogeneous (103 different, 22 novel)

Standardization of factor VII/activated factor VII measurement in plasma of patients treated with recombinant factor activated VII

Blood Coagulation & Fibrinolysis, 2003
To improve the standardization of the factor VII clotting activity (FVII:C) assay in patients treated with recombinant activated factor VII (rFVIIa), we conducted a multicentre study on plasma samples from four patients with haemophilia A, before and at various times after injection of a single dose of rFVIIa.

Assessment of Factor VII and Factor X

Thrombosis and Haemostasis, 1966
SummaryA method is described to separate factor VII from factor X in normal serum using electrophoresis in a polyvinyl chloride block. A potent source of factor X is obtained. This may be used in correction studies and for assessment of deficiencies of factor VII in patients.

How to Measure Factor VII and Factor VII Activation

Pathophysiology of Haemostasis and Thrombosis, 1983
This communication describes the different techniques that can be used to evaluate the activity state of factor VII in plasma samples. At the present time direct methods for quantitation of activated factor VII (factor α-VIIa) are not available. Combined methods are therefore used to measure the degree of factor VII activation.

Factor VII deficiency and its treatment in delivery with recombinant factor VII

European Journal of Obstetrics & Gynecology and Reproductive Biology, 2004
The authors present two cases of pregnant women with coagulation disorders--one with inherited deficiency of factor VII and the second with chronic hepatitis. Both cases were successfully treated with recombinant activated factor VII of coagulation (NovoSeven) in delivery. The advantages of using this product are discussed.
