[Prevalence of HCV, HBV and HIV infections among severe Polish haemophiliacs].

[Acquired haemophilia].

Acquired haemophilia (AH) is a severe bleeding diathesis that affects both males and females. It is caused by suddenly appearing autoantibodies that interfere with coagulation factor VIII (FVIII) activity. Although some conditions such as autoimmune diseases, cancer and puerperium seem likely to induce AH, in more than half of the observed cases autoantibodies to FVIII are idiopathic.
