Two cases of von Willebrand disease (VWD) that revelaed an increased ristocetin-induced platelet aggregation (RIPA) and a qualitative abnormality of the factor VIII protein are reported. The threshold concentration of ristocetin giving a 30% increase in light transmission was 0.5 mg/ml in the proband and 0.4 mg/ml in her father (normal: 1.16 +/- SD 0.18 mg/ml) although both patients showed reduced plasma von Willebrand factor activity (VIIIR:WF). In both patients, the amount of factor VIII related antigen (VIIIR:AG) in their platelets were normal, but an increased binding affinity of platelets to plasma factor VIII was demonstrated. The qualitative abnormality of the factor VIII protein was characterized by an increasead anodal migration of VIIIR:AG in crossed immunoelectrophoresis (CIE), a delayed elution pattern as demonstrated by gel filtration on Sepharose 2B, and a decreased precipitation with concanavalin A (Con A). The response to DDAVP was also investigated.
