Acquired von Willebrand’s Syndrome during Autoimmune Disorder

Summary

A case with evidence of acquired von Willebrand’s syndrome associated with systemic lupus erythmatosus and Sjögren’s syndrome is described. The patient, who had no family history of bleeding, presented a haemorrhagic diathesis of recent origin, the bleeding time was prolonged, procoagulant Factor-VIII and von Willebrand factor levels were low and platelet aggregation was decreased with different concentrations of Ristocetin®.

No improvement was seen after the tranfusion of cryoprecipitates, and there was no increase in procoagulant Factor-VIII.

Clinical improvement resulted after treatment with corticosteroids, and later, the laboratory abnormalities characteristic of von Willebrand’s disease became normal. The level of procoagulant factor-VIII reached the very high level of 810%.
