Von Willebrand disease (VWD) is the most common hereditary blood-clotting disorder in humans. An acquired form can sometimes result from other medical conditions. [1] It arises from a deficiency in the quality or quantity of von Willebrand factor (VWF), a multimeric protein that is required for platelet adhesion.
Vonicog alfa, sold under the brand names Vonvendi and Veyvondi, is a medication used to control bleeding in adults with von Willebrand disease (an inherited bleeding disorder). [6] [5] [7] [8] It is a recombinant von Willebrand factor. [6] [5] The most common adverse reactions are generalized itching, vomiting, nausea, dizziness, and vertigo. [6]
The von Willebrand factor type A (vWA) domain is a protein domain named after its occurrence in von Willebrand factor (vWF), a large multimeric glycoprotein found in blood plasma. Mutant forms of vWF are involved in the aetiology of bleeding disorders. [ 2 ]
Von Willebrand factor (VWF) (German: [fɔn ˈvɪləbʁant]) is a blood glycoprotein that promotes hemostasis, specifically, platelet adhesion.It is deficient and/or defective in von Willebrand disease and is involved in many other diseases, including thrombotic thrombocytopenic purpura, Heyde's syndrome, and possibly hemolytic–uremic syndrome. [5]
Von Willebrand factor type D domain (vWD) is an evolutionarily-conserved protein domain found in, among others, the von Willebrand factor (vWF). vWF is a large multimeric glycoprotein and it is synthesized by a type of bone marrow cell called megakaryocytes. The vWD domain allows vWF to perform its blood-clotting function by carrying factor ...

Desmopressin, sold under the trade name DDAVP among others, is a medication used to treat diabetes insipidus, bedwetting, hemophilia A, von Willebrand disease, and high blood urea levels. [1] In hemophilia A and von Willebrand disease, it should only be used for mild to moderate cases. [1]
In an unknown fashion, the antibiotic ristocetin causes von Willebrand factor to bind the platelet receptor glycoprotein Ib (GpIb), so when ristocetin is added to normal blood, it causes agglutination of fixed platelets or initiates the initial agglutination phase of aggregation of live platelets.
