In this study, anion-exchange chromatography was used to purify factor VII and factor IX from prothrombin complex (PPSB), which contains coagulation factors II, VII, IX and X. For this purpose, DEAE-Sepharose CL-6B gel , Pharmacia column XK-26 , high flow rate and two stepwise gradients with phosphate citrate buffer were used. The yield of the two lyophylized products, factor VII and factor...

Preventive subcutaneous treatment of severe hemophilia A with bispecific antibodies that mimic the action coagulation factor VIII (FVIII) is emerging as an effective alternative to replacement therapy intravenous administration FVIII concentrates, either derived from plasma or produced by biotechnology. Access this innovative therapeutic approach for a growing number patients worldwide increasi...

Prothrombin complex concentrates (PCCs) contain vitamin K-dependent clotting factors (II, VII, IX, and X) and are marketed as 3 or 4 factor-PCC formulations depending on the concentrations of factor VII. PCCs rapidly restore deficient coagulation factor concentrations to achieve hemostasis, but like with all procoagulants, the effect is balanced against thromboembolic risk. The latter is depend...

Acquired haemophilia A (AHA) is a rare hemorrhagic disease caused by an autoantibody against coagulation factor VIII. Nonhaemophiliac patients develop autoantibodies (inhibitors) directed against the factor VIII circulating coagulation protein. Disease is associated with an increased morbidity and mortality. Inhibitors against FVIII induce acute and life-threatening hemorrhagic diathesis becaus...

background recombinant activated factor vii (rfviia; novoseven® rt, novo nordisk, bagsvaerd, denmark) is a synthetic pro-coagulation factor derived from hamster kidney cells. objectives the purpose of this study was to evaluate the prescribing patterns of recombinant factor viia (rfviia) at a single, tertiary care pediatric hospital by indication of usage and dose administered. materials and me...

Prothrombin complex concentrates are haemostatic blood products containing four vitamin K-dependent clotting factors (II, VII, IX and X). They are a useful, reliable and fast alternative to fresh frozen plasma for the reversal of the effects of oral anticoagulant treatments (vitamin K antagonists). They are sometimes used for factor II or factor X replacement in patients with congenital or acqu...

multiple sclerosis (ms) is a neuroinflammatory autoimmune disease which mediated by various molecular and cellular immune components however recent reports have shown that coagulation factors that traditionally separate from the immune system might also be involved in ms development and progression.studies on experimental autoimmune encephalomyelitis (eae) and human ms patients reports alterati...

One of the last remaining clinical hurdles in the treatment of people with hemophilia is the development of inhibitors. Alloantibodies or autoantibodies directed at coagulation factors render the infusion of coagulation factor concentrates ineffective, and alternative means must be used to achieve hemostasis. Recombinant factor VIIa (rFVIIa) was developed to control bleeding episodes in hemophi...
