The incidence of a "pre-peak" over the well on crossed immunoelectrophoresis of factor VIII-related antigen (VIIIR:Ag) was found to be not significantly different in groups of hemophilia carriers and non-carrier women. Only 10% of hemophiliacs more than three days post-transfusion exhibited the feature. Upon transfusion 5 out of 6 hemophiliacs showed a transient appearance of the pre-peak. It was also present during pregnancy in 6 of 8 normal women, 2 hemophilia carriers and two von Willebrand's patients. The pre-peak pattern was quite reproducible both in the same sample tested on different days and in different samples from the same subject. The pre-peak material shows a line of treatment of plasma and by cryoprecipitation.

Liver dysfunction in patients with hemophilia A, B, and von Willebrand's disease.

Ninety-five patients with Hemophilia A, B and von Willebrand's disease followed over a three year period were evaluated for liver disease. Half of the patients were treated episodically and half received additional prophylactic treatment. Fifty-five per cent have significant transaminitis (elevated SGOT-SGPT), 42 per cent have biochemical evidence of chronic active liver disease and two per cent have subacute and active cirrhosis. There is an annual attack rate of Hepatitis B disease of 3.5 per cent and Hepatitis B antibody titres are present in 84 per cent. This asymptomatic liver disease requires close monitoring for clinical significance.
