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

Recombinant factor VIIa improves clot formation but not fibrolytic potential in patients with cirrhosis and during liver transplantation.

Etiology of bleeding in cirrhotic patients during surgery is multifactorial, and its management includes several measures such as replacement of coagulation factors and platelets as well as the use of antifibrinolytic agents. Recombinant factor VIIa has been shown to normalize prothrombin time in patients with liver disease and to reduce transfusion requirement during OLT. In […]
