Overview
Von Willebrand’s Disease:
Historical Perspective
Von Willebrand’s Disease(vWD) was first discovered by Erik Adolf von Willebrand, a Finnish Physician, in 1926, in a Swedish-language article “Hereditär pseudohemofili” ("Hereditary pseudohemophilia") after assessing a 5 year-old Finnish Girl and 66 members of her family from 1924-1926. In 1957, decreased level of a plasma factor ‘ Factor ⅷ later called ‘Von Willebrand factor’ were first identified in the pathogenesis of Von Willebrand’s Disease. In early 1970s Ristocetin was used to diagnose vWD after inducing platelet aggregation [1] . Later immunoprecipitation techniques were used to understand vWD and it’s varieties.
Classification
vWD may be classified according to Hereditary and Aquired causes. vWD is sub-classified according to Hereditary in four types.
- Type 1
- Type 2: Type 2 is further divided into 4 subtypes: 2A, 2B, 2M, 2N
- Type 3
- Pseudo or platelet-type
Aquired vWD is thought to be caused by Autoantibodies. It can be subclassified into lymphoproliferative, cardiovascular, myeloproliferative, neoplastic, autoimmune disorders [2].
Another classification has been made by The International Society On Thrombosis And Hemostasis on the basis of Qualitative and Quantitative defects of vWF [3].
