Alloantibody formation occurs in 10-15% of patients with type 3 disease. Therefore, the possibility of this complication must be managed appropriately, because patients are at increased risk for life-endangering anaphylactic reactions to vWF-FVIII preparations. With hemostatic stress in emergency situations, infusion of FVIII preparations devoid of vWF, while adjusting for the markedly decreased FVIII half-life, may be necessary.
