Factor VII (formerly known as proconvertin) is one of the central serine protease class.

Physiology

The main role of factor VII (FVII) is to initiate the process of coagulation in conjunction with Factor IX.

The action of the factor is impeded by anticoagulants impairs its function.

Genetics

The gene for factor VII is located on chromosome 13 (13q34).

Role in disease

Deficiency is rare (congenital proconvertin deficiency) and inherits recessively.

Therapeutic use

Recombinant human factor VIIa (NovoSeven®, eptacog alfa [activated], ATC code B02BD08) has been introduced for use in uncontrollable bleeding in hemophilia patients (with IX deficiency) who have developed inhibitors against replacement coagulation factor.

It is being increasingly used in uncontrollable hemorrhage.[1] The first report of its use was in an Israeli soldier with uncontrollable bleeding in 1999.[2] The rationale for its use in hemorrhage is, that it will only induce coagulation in those sites where tissue factor (TF) is also present. Still, O'Connell et al report an increased risk of deep vein thrombosis, pulmonary embolism and myocardial infarction in association with the use of rhFVIIa.[3]

According to a 2005 study, recombinant human factor VII improves outcomes in acute intracerebral hemorrhage.[4]
