The use of recombinant factor VIIa in children with inherited platelet function disorders.

This is an interesting report on a small series of children with inherited platelet dysfunction treated with rFVIIa for acute bleeding or preoperatively. Response seemed to correlate with type of underlying condition, severity of bleeding and delay in presentation. In this series rFVIIa had variable efficacy in securing hemostasis. There was no difference in requirement […]

The interaction between platelets and factor VII/VIIa.

This is a clearly written article detailing the mechanism of action of rFVIIa and its interaction with tissue factor and platelets leading to its hemostatic effect in hemophilia patients with inhibitors and those with platelet disorders. – Maadh Aldouri

The effect of recombinant factor VIIa on coagulopathic pigs with grade V liver injuries.

This study illustrates one of the unusual situations in Medicine where evidence of drug efficacy in human preceded animal studies. After the publication of several case reports on the effectiveness of rFVIIa in controlling traumatic bleeding, this study proves its efficacy in reducing bleeding after grade V liver injury in hypothermic dilutionally coagulopathic pigs, as […]

Survey of the use of whole blood in current blood transfusion practice.

This survey reflects the current situation in England and North Wales, where the prevailing opinion is that only the use of blood components is state of the art. There is decreasing need of source plasma for the industrial production of plasma derivatives due to recombinant products. England cannot use the plasma due to fear of […]

Use of recombinant factor VII in hepatology.

This article starts with a general overview on mechanism of action, uses and safety of rFVIIa as well as the hemostatic disorders which are associated with liver disease. It states the correlation between the degree of liver damage and level and gene expression of FVII. The authors reviewed the use of rFVIIa in liver disease […]

Recombinant activated factor VII for adjunctive hemorrhage control in trauma.

This is a relatively new area for using rFVIIa, which is to treat uncontrolled haemorrhage in patients with severe trauma, following the earlier report of using rFVIIa successfully in treating bleeding in a soldier who suffered with bullet injur (Kenet et al., Lancet 1999;354:1879). rFVIIa was effective in controlling bleeding and resulted in significant reduction […]
