How we choose factor VIII to treat hemophilia

How we choose factor VIII to treat hemophilia.

In high-income countries, the large availability of coagulation factors for replacement therapy of patients with hemophilia A has raised the life expectancy of these lifelong bleeders to that of males from the general population. The practicing clinician is offered a multitude of choices among several commercial brands of factor VIII extracted from human plasma or engineered from mammalian cell...

How I treat acquired Factor VIII inhibitors

Acquired hemophilia A is a rare bleeding diathesis caused by autoantibodies directed against clotting factor VIII and associated with an increased morbidity and mortality. This autoimmune disorder most commonly occurs in the elderly. Although it may be associated with several underlying pathologies, up to 50% of reported cases remain idiopathic. In contrast with congenital hemophilia, which is ...

Detection of Factor VIII Inhibitors in Hemophilia A Patients

Background: Factor VIII administration to hemophilia A patients results in an immune response (inhibitor formation) which significantly complicates the therapy. The present study was performed to determine the prevalence of inhibitor development in hemophilia A patients receiving recombinant factor VIII therapy. Materials and Methods: This was an observational descriptive study. Clotting fac...

Antibodies to factor VIII. V. Patterns of immune response to factor VIII in hemophilia A.

The natural history of factor VIII antibodies was studied in 20 severe, multitransfused hemophiliacs. Two patterns of humoral immune reactivity were observed. In one group of ten, who developed antibodies after an average of 22 cumulative exposure days to factor VIII, the antibody titers increased after each antigenic stimulation or persisted for years in the absence of transfusion. These patie...
