What is Von Willebrand Disease (VWD)?

VWD is the most common bleeding disorder in the general population, affecting males and females equally. Based the findings of population screening programs, it has been estimated that approximately 0.6% to 1.3% of people may be affected with some form of VWD.1 VWD is caused by deficiencies or abnormalities in the Von Willebrand factor (VWF), a large protein made up of multimers, or protein subunits. VWF binds to coagulation factor VIII (FVIII) and protects it against proteolytic degradation. In the process of hemostasis, VWF contributes to clot formation by facilitating platelet-platelet binding and platelet-endothelial cell adhesion at the injury site, leading to formation of a hemostatic plug. When VWF is defective or present in inadequate quantities, a person may exhibit symptoms such as difficulty forming a clot after an injury.

Types of VWD

Several subtypes of VWD can occur with a variable range of severity.2 Genetic mutations in the VWF gene have been identified for some of these subtypes.

  • VWD Type 1: The most common and often mildest subtype of VWD, in which VWF levels (and sometimes FVIII) levels are lower than normal;
  • VWD Type 2: The second most common subtype, featuring structurally abnormal VWF, and resulting in moderately severe disease. Type 2 is further divided into smaller groups, types 2A, B, M, and N:
    • Type 2A is characterized by a reduction in platelet binding due to a deficiency of high and intermediate weight VWF multimers;
    • Type 2B demonstrates an actual increase in binding of VWF to platelets due to an increased affinity of VWF for the platelet glycoprotein 1b receptor, leading to rapid clearance of the platelets and loss of the high molecular weight multimers in the plasma. This results in abnormal function.
    • Type 2M, a rare type of VWD, is characterized by greatly reduced platelet adhesion despite normal distribution of all multimers.
    • Type 2N, which is rare, demonstrates a markedly decreased affinity for FVIII.
  • VWD Type 3: The least common and most severe form of VWD, in which an individual inherits an altered gene from both parents. VWF may be almost completely absent in these patients, and they often have markedly decreased FVIII and ristocetin cofactor activity levels.
  • Pseudo (or platelet-type) VWD: Clinically similar to VWD Type 2B, pseudo VWD is caused by defects in the platelet receptor for VWF rather than a defect or deficiencies of VWF. Platelet glycoprotein Ib receptor has increased affinity for VWF leading to increased binding of platelets to VWF, subsequent loss of high molecular weight multimers with altered VWF function, and increased platelet clearance.

Prevalence of VWD in the US Population

The Centers for Disease Control and Prevention collect data on patients with bleeding disorders as part of the Universal Data Collection (UDC) Project. This database provides the prevalence of different subtypes of VWD seen among patients treated at hemophilia treatment centers in the United States. This database (accessed April 04, 2010) currently includes 5505 patients with VWD, of whom 83.5% (4597) have Type 1, 10.8% (595) have Type 2, and 5.7% (313) have Type 3.

Causes of VWD

VWD is a hereditary bleeding disorder caused by quantitative (Types 1 and 3) or qualitative abnormalities (Type 2) of the Von Willebrand Factor (VWF).3 VWD is transmitted on an autosomal (non-sex linked) chromosome, meaning that children of both genders are equally likely to inherit the gene. There are subtle differences in inheritance patterns depending on the type of VWD:

  • VWD Type 1: If either parent has an altered gene resulting in VWD Type 1, there is a 50% chance that each child of that parent will inherit the VWD gene. However, for reasons not yet understood, in some cases the VWD gene is present but “non-penetrant”, meaning that it does not result in clinically evident VWD in the individual. However, there remains a 50% chance that the individual will pass the gene on to offspring who may (or may not) express VWD Type 1.
  • VWD Type 2: As with Type 1, if either parent has an altered gene resulting in VWD Type 2, there is a 50% chance that the children of that parent will inherit the VWD gene. However, unlike the Type 1 gene alteration, the gene for Type 2 is always expressed when it is present, such that the person with the gene will have clinical evidence of VWD Type 2.
  • VWD Type 3: The most severe form of VWD, Type 3 occurs when both parents have an altered gene resulting in some form of VWD and their child receives an altered VWD gene from each parent. When both parents have an altered gene for VWD Type 1, there is:
    • 25% chance that each child will have VWD Type 3;
    • 50% chance that each child will inherit a gene for VWD Type 1;
    • 25% chance that each child will not inherit an altered VWD gene.

Signs & Symptoms of VWD

Many of the signs and symptoms of VWD resemble those observed in patients with platelet defects. Bleeding symptoms in VWD tend to be mucocutaneous in nature. The most common symptoms in persons diagnosed with VWD include4:

  • Nose-bleeding (epistaxis) (see IHTC’s informational brochure)
  • Abnormal or easy bruising (ecchymoses or hematomas)
  • Gingival bleeding
  • Postoperative bleeding
  • Gastrointestinal bleeding
  • Urogenital tract bleeding

Patients are brought to the attention of a hematologist due to abnormal bleeding after surgical procedures such as:

  • Bleeding after tonsillectomy and adenoidectomy
  • Bleeding after dental extractions, such as wisdom teeth
  • Bleeding after urogenital surgical procedures

Women may experience bleeding complications related to menstrual cycles and labor and delivery. Prevalent symptoms in women may include:

  • Menorrhagia – abnormal, excessive and/or prolonged menstrual bleeding; a critically important clinical issue in females, affecting up to 95% of women with VWD.1,5
  • Metrorrhagia – bleeding between periods
  • Postpartum bleeding: Heavy bleeding and/or hemorrhage during or after labor or delivery

VWD Type 3 is characterized by a virtual absence of VWF and may share the clinical symptoms and complications associated with moderate to severe FVIII deficiency. For instance, patients with Type 3 VWD, may experience hemarthrosis (bleeding into the joints or joint spaces)3, because of associated deficiency of FVIII. For more information on FVIII deficiency (hemophilia A), click here.

Emergency Care

If your patients with a bleeding disorder need to visit the emergency department (ED), encourage them to contact the IHTC so that the center can help them get the best possible emergency and follow-up care. Visit our webpage on Emergency Care to learn about what patients and their families should do, what they need to take to the ED, and what information they need to provide to the ED staff. Inform your patients about the IHTC’s useful Emergency Care Tips.

Diagnosis of VWD

Accurately diagnosing VWD Type 1 can be a challenge. Many bleeding symptoms associated with VWD, including menorrhagia, are common in unaffected populations, making it difficult to differentiate between normal and abnormal bleeding. Moreover, because VWD runs in families, symptoms such as easy bruising, oral bleeding, and menorrhagia seem “normal” to family members and are therefore not recognized as potential symptoms of a bleeding disorder. Clinicians should obtain a comprehensive patient and family history to identify abnormal bleeding symptoms. In general, clinicians need to take into account 4 components:

  1. Personal history of bleeding
  2. Family history of bleeding
  3. Physical examination
  4. Laboratory testing

Initial tests commonly used to evaluate individuals for a bleeding disorder include:1,4:

  • Complete blood count (CBC) and platelet count
  • Prothrombin time (PT)
  • Activated partial thromboplastin time (aPTT)
  • Thrombin time (TT) and/or fibrinogen testing
  • Fibrinogen

These tests are insensitive to detect VWD; therefore, specific tests are required if the patient or family history is suspicious. 1,4:

  • Platelet function (PFA-100 bleeding time)
  • FVIII activity
  • Ristocetin cofactor activity (VWF:RCo) – VWF functional analysis
  • VWF antigen level (VWF:Ag)– VWF quantitative analysis
  • VWF multimers – VWF qualitative analysis
  • Blood type

Calculations such as the ratio of VWF:RCo to VWF:Ag may be helpful in the differentiation of subtypes of VWD Type 2 (2A, 2B, 2M).1 Similarly the ratio of VWF:Ag to FVIII levels may help indicate Type 2N VWD.

Establishing a diagnosis of VWD Type 1 may require repeated testing. Plasma levels of VWF can fluctuate dependent on a variety of factors, including physical or emotional stress, exercise, systemic inflammation, pregnancy, and administration of oral contraceptives. These variables have the potential to elevate VWF levels and cause a false-negative result. Establishing a diagnosis of VWD Types 2 and 3 is more straightforward.1

The Medical and Scientific Advisory Council (MASAC) of the National Hemophilia Foundation (NHF) advises that VWD and other inherited bleeding disorders should be considered in the differential diagnosis of all females presenting with menorrhagia.6 Project Red Flag, the NHF’s public awareness campaign, estimates that more than 2.5 million women in the United States have an undiagnosed bleeding disorder.4 Moreover, particularly in women, there is a significant delay between initial clinical symptoms and diagnosis, with symptoms starting at a median age of 12 years and diagnosis occurring at a median age of 16 years (P=0.0049).5

Treatment of VWD

Treatment and management of VWD is determined by the subtype and severity of disease, as well as the patient’s age and symptoms. Prevention of bleeding is a primary treatment aim. Specific treatment options are available to increase the levels of VWF. In addition, supportive therapies can be used to prevent or control the bleeding symptoms. The main treatment options include:7,8

  • Desmopressin acetate (DDAVP; Stimate) nasal spray or injection
    • Synthetic hormone that increases the release of endogenous stores of VWF.
    • Indicated for use in patients with Type 1 VWD and in hemophilia patients with mild factor FVIII deficiency (>5%).
    • Nasal spray recommended only for patients >3 years old and weighing more than 20 kg
    • To use desmopressin, patients should undergo a DDAVP challenge test to determine if they exhibit a hemostatic response, because it is not effective in all patients.
    • Click here to download the IHTC’s fluid restriction guidelines and other information on DDAVP/Stimate use.
  • VWF-containing concentrates (eg, Humate-P)
    • These concentrates are derived from human blood that has undergone viral inactivation.
    • These concentrates are administered via intravenous route to increase the level of VWF.
    • Indicated for:
      • patients with VWD Type 2A, 2B, 2M and 3
      • Type I with severe bleeding
      • patients who are unresponsive or have contraindications to desmopressin (DDAVP);
      • patients undergoing major surgical procedures involving areas of fibrinolysis, such as oropharyngeal region or urogenital area
  • Aminocaproic acid
    • Antifibrinolytic agent indicated for use in patients with bleeding disorders
    • This agent prevents the breakdown of a blood clot and helps to maintain hemostasis
    • Used to treat mucous membrane bleeding
    • Commonly used as an adjunctive treatment along with DDAVP/Stimate or VWF-containing concentrates
  • Oral contraceptives
    • Indicated for use in women whose primary symptom is menorrhagia or metrorrhagia
  • Other adjunctive therapies
    • May include local fibrin glue, microfibrillar collagen, or tranexamic acid.
  • Other measures that may be taken to reduce complications associated with VWD include the following:
    • Advise patients to avoid medications that may increase bleeding, such as aspirin or other antiplatelet drugs
    • Use precaution when administering recommended immunizations: give injections in the thigh or other large muscle group(s) using the smallest gauge needle
      • No more than one immunization in one muscle group per visit
      • Apply ice and pressure after immunization for 3 to 5 minutes each
    • Vaccinate patients against hepatitis A and B if not immune or not previously exposed
      • Advise people with bleeding disorders that they have an increased risk of exposure to blood and blood products
  • Identify bleeding problems early and treat as soon as possible
  • Advise patients to maintain an ideal weight and an active lifestyle to increase muscle tone and preserve joint function.

Treatment Adherence in VWD Care

The effectiveness of treatment of VWD depends on two important variables: the physician recommending an appropriate treatment plan for the patient’s condition, and the patient following the recommendations provided. Treatment adherence is the extent to which a patient’s behavior coincides with medical or health advice. Individuals with type 3 VWD may share the clinical symptoms and complications associated with moderate to severe hemophilia. Because individuals with type 3 VWD often require infusion therapy at home, they must be actively involved in working with physicians to plan and manage their treatment regimen.

Poor adherence to a treatment plan may reduce treatment effectiveness and contribute to long-term disability and decreased quality of life in patients with type 3 VWD. Nonadherence to on-demand/episodic therapy may result in bleeding episodes of longer duration, recurrent bleeds in the same location, joint damage and subsequent disability. Nonadherence to prophylactic therapy may cause suboptimal prevention of bleeding events and lead to the poor outcomes. Because clotting factor and other medications for the treatment of type 3 VWD are expensive it is especially important for patients to adhere to treatment recommendations to prevent complications and reduce waste of valuable medical resources.

While most healthcare providers agree that treatment adherence is an important issue in health outcomes, historically there has not been an effective way to measure treatment adherence in individuals with bleeding disorders. Different studies of individuals with hemophilia have used infusion logs, clotting factor dispensations, joint health, and patient interviews to evaluate adherence. However, none of these studies resulted in a standardized method to measure adherence to hemophilia treatment. In response to the need for a standardized adherence measure, the IHTC developed and validated two scales to measure treatment adherence – the Validated Hemophilia Regimen Treatment Adherence Scales (VERITAS) for episodic treatment (VERITAS-PRN) and for prophylactic treatment (VERITAS-Pro).

VERITAS: IHTC’s Validated Treatment Adherence Scales

Each VERITAS scale includes 24 questions divided into six 4-question subscales. The subscales are designed to measure different aspects of treatment adherence, including the dosage and timing of infusions, the patient’s tendency to forget or skip infusions, and the frequency of communication between the patient and the HTC. Using the individual subscale scores as well as the total score allows care providers to evaluate multiple dimensions of adherence and to identify areas that should be addressed to improve adherence and optimize long-term health outcomes for the patient.

The validation process involved developing these questionnaires and testing them in patient groups to demonstrate that the scales measure what they purport to measure, i.e., that they measure actual treatment adherence and not another aspect of treatment. We demonstrated that the scales reliably measure treatment adherence and represent a valuable tool for use in patient care. The scales take less than ten minutes to complete and are a simple and highly informative addition to a patient’s clinic visit and care.

Both scales were published in Haemophilia, a leading peer-reviewed journal, in early 20109,10 and have been well received in the hemophilia community. To date, the IHTC team has presented the scales at the American Society of Hematology, World Federation of Hemophilia, the International Network for Pediatric Hemophilia, and the first Conference on Blood Disorders in Public Health. The VERITAS-Pro is currently undergoing translation into Spanish, Italian, and French, and has been introduced to multiple clinic settings and added to several pharmaceutical study protocols. It is our hope that the VERITAS scales will improve our understanding of the link between treatment adherence and health outcomes, and thus significantly influence our ability to help patients achieve the best long-term outcomes possible.

Hemophilia Treatment Centers and Comprehensive Care

The federal Office of Maternal and Child Health and the Centers for Disease Control and Prevention (CDC) support a network of specialized healthcare centers dedicated to treating blood disorders.11 Currently, the network includes approximately 140 HTCs. The IHTC is Indiana’s only federally recognized HTC.

The purpose of HTCs is to prevent and reduce problems related to blood disorders by providing optimal and comprehensive care to persons with bleeding disorders, thrombosis, thrombophilia (clotting disorders), and other blood disorders. The centers use multidisciplinary clinic teams, and clinical, outreach, and education programs. The multidisciplinary team may include:

  • adult and pediatric hematologists
  • triage and clinic nurses
  • social workers and other mental health professionals
  • dental hygienists
  • research coordinators
  • physical therapists

The teams work closely with local healthcare providers to meet the specific needs of the population to improve their quality of life. The care provided at HTCs has been shown to significantly decrease complications for persons with hemophilia. Mortality rates are 40% lower in persons who use HTCs than in those who do not, despite the fact that the more severely affected patients are the ones who typically visit these centers.12 HTCs place a premium on preventive care because of the difficulty and expense of treating complications of bleeding disorders, which can reduce the patients’ quality of life.

The IHTC exceeds national staffing standards and offers an extensive spectrum of care and services through dedicated trained professionals. In addition to the core services provided at all HTCs (e.g., hematologists, clinical nurses, social workers, physiotherapists), the IHTC staff also includes a career counselor, risk reduction specialists, a registered dietitian, genetic counselor, dental hygienists, and clinical research professionals.

For more about the value of comprehensive care, go to IHTC’s informational brochure, “Why Attend Comprehensive Clinic?”

IHTC’s Disease Management Program: Optimizing Patient Care While Minimizing Costs

Since October 2004, the IHTC has administered a disease management program (DMP) for persons with bleeding disorders who are insured by Indiana’s high-risk insurance pool, the Indiana Comprehensive Health Insurance Association (ICHIA). Indiana code I.C. 27-8-10-3.5(e) mandates that ICHIA-insured individuals with chronic diseases participate in an ICHIA-approved DMP. Because of IHTC’s specialized focus on bleeding disorders and commitment to excellence in patient care, it was selected as the disease management entity for ICHIA-insured individuals with bleeding disorders.

The purpose of the DMP is to optimize patient care and health outcomes while containing or reducing costs of care. The program brings together expertise, experience, and advanced technology in a patient-focused, research-oriented approach. Included elements of the DMP are targeted toward the most accurate, effective, and efficient methods to diagnose and treat bleeding disorder complications. Through targeted interventions and enhanced quality assurance, this program is expected to result in improved patient care and cost stabilization/savings.

Eligibility Criteria

Patients enrolled in the program are required to do the following:

  • Attend an annual comprehensive clinic at the IHTC or at an outreach location;
  • Have prescriptions for clotting factor concentrate and other bleeding disorder medications signed by an IHTC physician;
  • Obtain outpatient clotting factor and related products through one of the ICHIA DMP Public Health Service vendors, such as the IHTC Pharmacy Program;
  • Engage in periodic telephone contact with IHTC/DMP nurses and staff regarding ongoing health issues, psychosocial concerns, and educational or occupational needs;
  • Complete DMP questionnaires and assessments upon request;
  • Use the ATHNadvoy web-based infusion reporting system or other approved infusion reporting system to log infusions.

Program enrollees also have the option to participate in the research component of the DMP, whereby program results may be presented to other HTCs and/or published in academic journals. Patient privacy is always an IHTC priority. Any data that are published or presented are de-identified and aggregated so that no individual patient can be linked to the information.

Evaluation of Progress

The following tools are used to evaluate program progress:

  • Monthly meetings of the multidisciplinary team to review DMP patients’ health status, progress, and needs;
  • Pharmacoeconomic analysis of claims data – i.e., annual insurance claims are reviewed from year to year, with a special focus on costs of care, costs of clotting factor, source of care (e.g., HTC, emergency department), and changes in costs and utilization from one year to the next;
  • Annual reporting of specific cost and utilization outcomes:
    • Average costs of clotting factor, medical, and hospital care;
    • Average number of clotting factor units dispensed, emergency department visits, and inpatient hospital days;
  • Regular patient assessments:
    • Diagnosis-specific knowledge assessments – to assess a patient’s knowledge of his or her own condition, and to assess changes in knowledge over time;
    • Quality of life survey – to assess a patient’s health-related quality of life, and to assess changes in quality of life over time;
    • Treatment adherence scale – VERITAS-Pro or VERITAS-PRN for patients who use a home infusion regimen.

Outcomes Data

The DMP is currently in its sixth year of administration. Five years after implementation, all costs, as well as emergency department visits, have remained below pre-implementation levels. Inpatient hospital days also have remained below pre-implementation, although a few spikes in costs for medically necessary surgeries have occurred. Program patients have benefited from the focus on proactive, preventive care and personalized interventions. A major strength of the IHTC DMP is that it is administered by healthcare providers rather than a third-party disease management entity. This ensures that program staff has direct access to the multidisciplinary medical team, physicians, and pharmacy. This model strongly supports the implementation of provider-administered DMPs in managing costly chronic disease and addressing the rising healthcare costs in the United States.

The IHTC team published the initial results of its DMP in Haemophilia, a leading peer-reviewed, academic journal. To access the abstract of the published article, click here.

Special Considerations

It is important for primary care providers, gynecologists, surgeons, and dentists to obtain a bleeding history, and particularly a history of menorrhagia, prior to surgery or a procedure. In one study,5 7 out of 27 participants with menorrhagia underwent hysterectomy to control bleeding; yet in 6 of the 7, a diagnosis of VWD was not known preoperatively despite a previous bleeding history in all.

An international group of experts on the care of women with bleeding disorders recently published a consensus statement on how to specifically identify and manage bleeding disorders in women. Click here to download a free copy of the consensus statement.

Women with VWD who become pregnant or plan to have a child should receive follow-up care from a hematologist and obstetrician who are skilled in the management of VWD. The obstetrician should work with the hematologist to develop a plan to prevent bleeding and to manage bleeding if it does occur. Pregnancies in women with VWD are often considered to be high risk; and delivery should occur at a facility with the capability to manage potential bleeding complications. The National Hemophilia Foundation’s MASAC recently updated its guidelines for perinatal management of women with bleeding disorders and carriers of hemophilia A and B.

Recombinant VWF is available in clinical trials but is not available for routine clinical use. This means that patients with VWD must use plasma-derived concentrates, which may have an increased risk for transmitting blood-borne infections such as hepatitis A, B or C, and HIV. However, intensive screening, testing and advanced purification processes have greatly reduced this risk. IHTC’s risk reduction specialist counsels individuals with bleeding disorders about steps they need to take to reduce or prevent complications related to their bleeding disorder or its treatment.

Full details of current guidelines for the management of VWD are available in the National Heart Lung and Blood Institute publication, “The Diagnosis, Evaluation, and Treatment of von Willebrand Disease”1. The guidelines have also been published in the journal Haemophilia.13
