Diagnosis and management of von Willebrand disease in The Netherlands.

In the Netherlands, specialized care for patients with a bleeding disorder, including hemophilia, von Willebrand disease (VWD), and allied disorders, is concentrated in 13 Hemophilia Treatment Centers. The Dutch Hemophilia Treaters Society, the Dutch Hemophilia Nurses' Society, and the Netherlands Hemophilia Patients Society collaborate to optimize management of patients with a bleeding disorder. A recently updated consensus guideline of hemophilia and allied bleeding disorders provide guidance on the current optimal diagnostic strategy and treatment of VWD. Genetic testing is not routinely performed in the Netherlands. Desmopressin (DDAVP) is the choice of treatment in VWD patients responsive to DDAVP, as determined by a test infusion. Coagulation factor concentrates are used in nonresponsive individuals, in case of a contraindication for DDAVP, or in type 2B and type 3 VWD. These concentrates are available for all patients in the Netherlands; however, these may only be administered in a Hemophilia Treatment Center or under the care of a Hemophilia Treatment Center. Recently a study on moderate and severe VWD (the Willebrand in Netherlands study) was initiated to obtain more insight on VWD diagnosis, treatment, and the burden of the disease. © Thieme Medical Publishers.
