Abstrakt: The aim of our study was to investigate whether haemophilia A patients with inversion of intron 22 are at high risk for non-inhibitory anti-FVIII antibodies development detected by ELISA. It is known that patients with severe forms of haemophilia A are more likely to develop anti-FVIII antibodies. The incidence of inhibitory anti-FVIII antibodies in patients with factor VIII gene inversion has been extensively evaluated, but if this defect has to be considered a predisposing factor is still debatable. Non-inhibitory anti-FVIII antibodies are attracting interest, due to the potential influence on FVIII half-life. Our data show that FVIII gene inversion was a major predisposing factor for anti-FVIII antibodies development.
