Factor VIII, an essential blood coagulation protein, [12] is used as a medication to treat and prevent bleeding in people with hemophilia A and other causes of low factor VIII. [ 13 ] [ 14 ] Certain preparations may also be used in those with von Willebrand's disease . [ 14 ]
Hemophilia A causes a deficiency in Factor VIII, a protein required for blood clotting. Factor VIII injections are a common treatment to prevent or stop bleeding in people with hemophilia A. [1] Contamination of these and other products caused large numbers of hemophiliacs to become infected with HIV and hepatitis C.
Factor VIII, factor VIII inhibitors, emicizumab Haemophilia A (or hemophilia A ) is a blood clotting disorder caused by a genetic deficiency in clotting factor VIII , thereby resulting in significant susceptibility to bleeding, both internally and externally.
Factor VIII is used in haemophilia A and factor IX in haemophilia B. Factor replacement can be either isolated from human plasma, recombinant, or a combination of the two. Some people develop antibodies (inhibitors) against the replacement factors given to them, so the amount of the factor has to be increased or non-human replacement products ...
Acquired haemophilia A (AHA) is a rare but potentially life-threatening bleeding disorder characterized by autoantibodies directed against coagulation factor VIII.These autoantibodies constitute the most common spontaneous inhibitor to any coagulation factor and may induce spontaneous bleeding in patients with no previous history of a bleeding disorder.
