Platelet von Willebrand factor in inherited and acquired bleeding disorders.
The majority of plasma proteins involved in the mechanisms of hemostasis are loosely adsorbed on the platelet surface. A few of them, however, can also be measured in washed platelets, in which they are contained in the intracellular organelles called a granules. The main proteins involved in blood coagulation concentrated in platelets are von Willebrand factor (vWF), fibrinogen, and factor V. ...
متن کاملAcquired von Willebrand syndrome in aortic stenosis.
BACKGROUND Aortic-valve stenosis can be complicated by bleeding that is associated with acquired type 2A von Willebrand syndrome. However, the prevalence and cause of the hemostatic abnormality in aortic stenosis are unknown. METHODS We enrolled 50 consecutive patients with aortic stenosis, who completed a standardized screening questionnaire to detect a history of bleeding. Forty-two patient...
متن کاملAcquired von Willebrand syndrome in myeloproliferative disorder
We present a woman (age: 57 years) with an excessive bleeding episode under acetylsalicylic acid after bone marrow puncture due to an acquired von Willebrand syndrome (avWS) in the context of a myeloproliferative disorder. The laboratory features showed a high platelet concentration and a qualitative defect of von Willebrand factor (vWF) with a low normal vWF ristocetin cofactor activity, a nor...
متن کاملZebrafish von Willebrand factor.
von Willebrand factor (vWF) is a large protein involved in primary hemostasis. A dysfunction in this protein or an insufficient production of the protein leads to improper platelet adhesion/aggregation, resulting in a bleeding phenotype known as von Willebrand disease (vWD). To gain a better understanding of vWF interactions in vivo, the use of zebrafish as a model is ideal because of the trans...

for repeat testing. The authors’ conclusion that it should be considered for screening patients requires further consideration and study but conceivably, this assay should improve the future of VWD diagnosis.
