von Willebrand Disease

Disease Background

Von Willebrand Disease (VWD) is an autosomal inherited bleeding disorder caused by a deficiency or dysfunction of von Willebrand factor (VWF) and is the most common bleeding disorder, found in up to 1% of the US population.

VWF, along with factor VIII (FVIII), is a key molecule in platelet aggregation and adhesion and is critical to prevent bleeding via blood clotting.

Typical symptoms of VWD include easy bruising, epistaxis, gingival bleeding, surgical bleeding, and heavy menstrual bleeding.

Characteristics of Types of VWD

Type Classification Description Bleeding Incidence3
   1  Quantitative  Partial deficiency of VWF  Variable from mild to moderate    ~85%
  2A  Qualitative  Defects in multimerization  Variable from moderate to severe    10-15%
  2B  Qualitative  Increase in spontaneous platelet binding  Variable from moderate to severe    10-15%
  2M  Qualitative  Defects in ligand binding with intact multimers  Variable from moderate to severe     10-15%
  2N  Qualitative  Defects in FVIII binding  Variable from moderate to severe     10-15%
   3  Quantitative  Severe deficiency of VWF  Severe      <1%

Diagnostic Process

The National Institute of Health recommends that assessments for diagnosis of VWD occur in two main stages:

1. Evaluation of clinical history

  • Family history and personal bleeding history (spontaneity and severity, sites of bleeding, duration of bleeding, type of injury associated with bleeding, ease with which bleeding can be stopped)

2. Laboratory evaluations

Treatment Options1,3,4,5

VWD Type Recommended Treatment
1 Desmopressin (if unresponsive to desmopressin use VWF/FVIII concentrates)
2 VWF/FVIII concentrates
3 VWF/FVIII concentrates

VWF concentrate dosing recommendation1

Major surgery/bleeding:

Loading dose Maintenance dose Therapeutic goal
40-60 U/kg 20-40 U/kg every 8 to 24 hours Trough VWF:RCo and FVIII>50 IU/dL for 7-14 days

Minor surgery/bleeding:

Loading dose Maintenance dose Therapeutic goal
30-60 U/kg 20-40 U/kg every 12 to 48 hours Trough VWF:RCo and FVIII>50 IU/dL for 3-5 days


* Antifibinolytic agents in combination with topical agents, or with desmopressin and VWF/FVIII concentrates, can also be used1
