Acquired von Willebrand's disease following bone marrow transplantation

A 41-year-old male underwent allogeneic bone marrow transplantation for the treatment of acute myelogenous leukemia. Six months later, he was admitted to a hospital with signs and symptoms consistent with worsening chronic graft-vs-host disease. Despite a negative past history for a bleeding diathesis, the patient was found to have absent factor VIII procoagulant and ristocetin cofactor activities with markedly reduced von Willebrand factor antigen, all consistent with a diagnosis of acquired von Willebrand's disease. Successful treatment of this disorder with aggressive apheresis and von Willebrand factor replacement therapy is noted.
