Target Audience
This activity has been designed to meet the educational needs of hematologists, oncologists, pathologists, pharmacists, hematology/oncology nurses, advanced practice registered nurses, internists, their support staff, and other healthcare professionals who are interested in the management of patients with von Willebrand disease (VWD).

Statement of Need/Program Overview
Von Willebrand disease is the most common hereditary bleeding disorder, yet its diagnosis and management can be complex. There are 6 different types of VWD, each having unique clinical and laboratory characteristics. Accurate diagnosis of inherited or acquired VWD is required to guide treatment decisions, but diagnosis can be challenging, and currently there are no standard diagnostic algorithms. Molecular analyses can aid in certain cases, but clinicians usually must rely on laboratory diagnosis, clinical characteristics, and patient family history, all of which can vary and/or be subject to interpretation.

Standard therapy for VWD includes treatment with DDAVP or plasma concentrate, with the specific therapy dictated according to VWD type and severity. Moreover, patients must be tested up front for their initial response to DDAVP prior to starting therapy, and there are differences between types of plasma concentrates, so clinicians should be familiar with treatment guidelines and differences in products.

In addition to these standard therapies, new treatments continue to be developed. The recent approval of recombinant von Willebrand factor (VWF) increases treatment options, but practitioners must know for which patients this product can be used, dosing and frequency, and how to accurately monitor factor levels. Continued development of recombinant VWF is likely to result in the availability of extended half-life factors, as seen with hemophilia. Awareness of these developments and ongoing clinical trials for eligible patients is necessary for practitioners who care for patients with VWD.

Educational Objectives
After participating in this activity, participants should be better able to:

  • Review current challenges in diagnosis of VWD
  • Assess laboratory test results in the context of the patient’s clinical and family history
  • Discuss newer methodologies to improve detection and classification
