We have used activation peptide release assays to compare factor VII and activated factor VII (VIIa) activation of factor X, normal factor IX (IXN), and a variant factor IX (IXBmLE), which, after activation, is unable to back-activate factor VII. In purified systems, factor VII and VIIa each rapidly activated factor X, but after a one minute lag for factor VII. VIIa also readily activated both ...
Bleeding remains a potential complication for patients requiring extracorporeal life support systems. Recombinant activated factor VII (rFVIIa) is one of the drugs used in controlling bleeding. Its use is generally found to be safe. We report a paediatric patient who developed fatal thrombosis with the use of rFVIIa whilst on extracorporeal membrane oxygenation and discuss the possible factors ...

Inherited factor VII (FVII) deficiency is a rare autosomal-recessive bleeding disorder. There are no clear guidelines regarding therapy in such patients when intracerebral surgery is performed. We report the use of recombinant activated FVII (rFVIIa) for the prophylaxis of bleeding in a female with FVII deficiency (8% of activity) undergoing urgent removal of a right fronto-rolandic intracerebr...
We have studied factor VII activation by measuring the ratio of factor VII clotting to coupled amidolytic activity (VIIc/VIIam) and cleavage of 125I-factor VII. In purified systems, a low concentration of Xa or a higher concentration of IXa rapidly activated 125I-factor VII, yielding a VIIc/VIIam ratio of 25 and similar gel profiles of heavy and light chain peaks of VIIa. On further incubation,...
Abstract Nowadays, bypassing agents such as recombinant activated factor VII (rFVIIa) and activated prothrombin complex concentrates (aPCC) are used to treat bleeding episodes in the Hemophilia patients with inhibitors. AryoSeven® is an Iranian biogeneric rFVIIa with homogeneity of efficacy and the nature to NovoSeven in a comparative trial. The current clinical trial aimed to evaluate the cost...
The authors have investigated the ability of platelets to enhance factor Xa-catalyzed activation of factor VII. Unstimulated platelets were without effect, whereas freeze/thawed platelets substantially enhanced activation. Antifactor V antibodies did not diminish the enhancement. Platelets activated by thrombin, collagen, or calcium ionophore A23187 also enhanced factor Xa-catalyzed activation ...
