Abstrakt: FVIIa purified from human plasma and spontaneously activated during the purification procedure was given to 4 patients with hemophilia A and inhibitors against FVIII:C in association with joint bleeds. A dose of 9-20 micrograms/kg b.w. (700-1,000 U/kg b.w.) seemed to be hemostatically active in moderate to severe joint bleeds. Plasma levels of FVII of 5-7 U/ml were achieved and recoveries varied between 17 and 66%. The lower recovery rates of 17-39% were all found in 1 of the patients. No immediate side effects were seen. Neither were any signs of a systemic activation of the coagulation system observed. It is concluded that highly purified FVIIa may be useful in the treatment of hemophilia A patients with inhibitors against FVIII:C.
