Thromb Haemostasis
-
The development of inhibitors in patients with mild/moderate hemophilia A is an increasingly recognized occurrence and is manifested by the patients' bleeding pattern becoming more severe. Inherited (hemophilia genetic mutations) and acquired (type and delivery of factor VIII replacement therapy) factors have been associated with an increased likelihood of developing factor VIII inhibitors. ⋯ Particular attention should be directed to the prevention of this complication in those patients with mild/moderate hemophilia recognized to be at increased risk of developing a factor VIII inhibitor. In conclusion, large prospective trials are warranted in order to elucidate the many still unclear pathogenic and therapeutic aspects of the development of inhibitors in patients with mild/moderate hemophilia A.
