Management of type 2b von Willebrand disease in the neonatal period

Von Willebrand disease (VWD) is the most common inherited bleeding disorder, affecting one in 1,000 people. Type 2b VWD is a less common subtype caused by a gain-of-function mutation in von Willebrand factor (VWF) that leads to the formation of large, ineffective VWF-platelet multimers in circulation. This unique pathophysiology creates diagnostic and treatment dilemmas. There is limited information on the management of type 2b VWD in the neonatal period. This report describes the management of a neonate with type 2b VWD with an emphasis on the added benefit of concomitant platelet transfusion and factor replacement therapy over factor replacement therapy alone.
