Von Willebrand's disease:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
Unlike hemophilia, von Willebrand’s disease is inherited as an autosomal dominant trait that affects males and females equally. One theory of pathophysiology holds that mild to moderate deficiency of factor VIII and defective platelet adhesion prolong coagulation time. Specifically, this results from a deficiency of the vWF, which stabilizes the factor VIII molecule and is needed for proper platelet function.
Defective platelet function is characterized by:
❑ decreased agglutination and adhesion at the bleeding site
❑ reduced platelet retention when filtered through a column of packed glass beads
❑ diminished ristocetin-induced platelet aggregation.
Recently, an acquired form has been identified in patients with cancer and immune disorders.
Von Willebrand’s disease, which doesn’t have any racial or ethnic associations, affects about 1% of the population.
