Prophylaxis in von Willebrand disease

Von Willebrand disease (VWD), the most common hereditary bleeding disorder, is divided into three types depending on the quantitative (type 1 and 3) or qualitative (type 2) abnormality of von Willebrand factor (VWF). About 70-80% of VWD patients can be treated with the synthetic product desmopressin, while the others necessitate factor VIII/VWF concentrates. In addition to the treatment of bleeding episodes, therapeutic regimens include short- or long-term prophylaxis. While the literature data on short-term prophylaxis in VWD are consistent and clearly show the safety and efficacy of such a therapeutic approach, little evidence is available regarding long-term prophylaxis, and although the preliminary results are encouraging, they need to be validated by large prospective studies.
