Key result
Low von Willebrand factor (30-50 IU/dL) is a complex disorder with variable bleeding phenotypes, reduced VWF biosynthesis, and enhanced clearance, distinct from type 1 VWD.
Why the study?
Management of patients with mild to moderate VWF reductions between 30 and 50 IU/dL is challenging, as bleeding phenotypes vary and pathogenesis remains incompletely understood.

Bleeding risk stratification in low VWF remains unreliable; leaves open identification of phenotypic modifiers for future studies.
Low von Willebrand factor is a complex disorder that falls between type 1 VWD and bleeding disorders of unknown cause, often requiring hemostatic treatment like tranexamic acid or desmopressin prior to elective procedures.
O’Donnell et al. (2023) conducted a review in Low von Willebrand Disease. Low von Willebrand factor (VWF) levels was evaluated. Low von Willebrand factor (30-50 IU/dL) is a complex disorder with variable bleeding phenotypes, reduced VWF biosynthesis, and enhanced clearance, distinct from type 1 VWD.
