Modeling response to high-purity von Willebrand factor: toward tailored dosing during surgery in von Willebrand disease.

ABSTRACT:

Abstract

In surgical settings, managing von Willebrand disease (VWD) often requires von Willebrand factor (VWF) concentrate administration, and close monitoring of factor VIII (FVIII) and VWF to balance bleeding control with the risk of excessive factor elevation. This management is further complicated by VWD-related variability and the pharmacokinetic (PK) impact of VWF products, containing or not exogenous FVIII. We hypothesized that building a PK model based on high-purity VWF concentrates may clarify the VWF-FVIII relationship by eliminating exogenous FVIII interference. Our aim was to characterize the PK/pharmacodynamic (PD) relationship and variability of a high-purity VWF concentrate in patients with VWD undergoing surgery. A retrospective analysis was conducted on patients
