Bleeding Disorder FAQ

What is a bleeding disorder?

Bleeding disorders occur when there is poor clotting due to deficient or missing proteins, called factor. These disorders can cause heavy and prolonged bleeding, either spontaneously or after an injury.

Hemophilia and Von Willebrand Disease (VWD) are two common bleeding disorders. Bleeding disorders can be mild, moderate, or severe in nature. Severe bleeding disorders are usually detected in infancy, while milder versions of the disease may not be diagnosed until adulthood. Many bleeding disorders, including hemophilia and VWD, are inherited conditions. There are other causes as well.

What is an inhibitor?

It is estimated that roughly 15 – 20% of people with hemophilia have an inhibitor. This is when the immune system produces an antibody (called an inhibitor) that destroys the clotting factor before it stops the bleeding. It is unclear as to why this happens. People with inhibitors experience much higher treatment costs than those who don’t develop this complication.

What are symptoms of bleeding disorders?

Bleeding can happen externally or internally, affecting joints, muscles, and other organs. External bleeds can be characterized by excessive bleeding, including menstrual bleeding, and bruising. Internal bleeds can cause severe pain, swelling, joint damage and joint destruction.

Who is affected by bleeding disorders?

Approximately 33,000 people in the United States have hemophilia, while roughly 3.2 million Americans have Von Willebrand Disease. All ethnic and socioeconomic groups are affected by bleeding disorders.

How are bleeding disorders treated?

There is no cure for hemophilia or Von Willebrand Disease.

Clotting factor replacement therapy, which involves an intravenous infusion of blood clotting products or a subcutaneous injection of a non-factor replacement therapy, enables those with bleeding disorders to lead normal and productive lives. Treatments must be given as soon as possible after the start of bleeding or taken regularly (as prophylaxis) to prevent uncontrolled bleeding. Mild VWD may also be treated with an intranasal medicine.

The average cost for treating hemophilia is about $300,000 annually, but some may require much more treatment every year. There are no generic substitutes for these treatments.

Where do people with hemophilia receive medical care?

According to the Center for Disease Control, 70% of people with hemophilia receive care from Hemophilia Treatment Centers (HTCs) staffed with doctors, nurses, and social workers. A list of HTCs in New England can be found by clicking here.

Mortality rates and hospitalization rates for bleeding complications from hemophilia were 40% lower among people who received care in an HTC than among those who did not receive this care. Others may receive care from their primary care physician or a local hematologist.

Where do people with hemophilia receive their “medication”?

People with hemophilia either get their “medication,” i.e. factor, through a 340B pharmacy at their Hemophilia Treatment Center (HTC) or through a Homecare Company. Homecare Companies are staffed with pharmacists and nurses who not only provide factor, but like HTCs, they also ensure patients have the proper supplies, know how to self-infuse at home, and provide a variety of services and information they need to maintain good health. There are almost a dozen pharmaceuticals that manufacture clotting factor. Representatives from these also provide information and support to patients with bleeding disorders.

Hemophilia

Hemophilia is a genetic disorder which creates problems in the body’s blood clotting system. It is caused by a deficiency of factor VIII or factor IX. As a result, stable clots do not form and prolonged bleeding occurs.

Diagnoses can be mild, moderate or severe, depending on factor levels in the individual’s blood. Contrary to popular myth, persons with bleeding disorders will not bleed to death from a cut or minor injury. They suffer mostly from internal bleeding into joints and muscles.

It is estimated that roughly 33,000 people in the United States live with hemophilia. While this affects males most severely, females can have hemophilia, too. Inhibitors in hemophilia present complicated treatment challenges.

Treatment for Hemophilia

There is no cure for hemophilia, yet.

Clotting factor replacement therapy, which involves an intravenous infusion of blood clotting products or a subcutaneous injection of a non-factor replacement therapy, enables those with bleeding disorders to lead normal and productive lives. Treatments must be given as soon as possible after the start of bleeding or taken regularly (as prophylaxis) to prevent uncontrolled bleeding.

The average cost for treatment for hemophilia is about $300,000 annually, but some may require much more treatment every year. There are no generic substitutes for these treatments.

According to the Center for Disease Control, 70% of people with hemophilia receive care from Hemophilia Treatment Centers (HTCs). These facilities are typically staffed with doctors, nurses, social workers, physical therapists, dentists, and many other specialists who help oversee the comprehensive care of people living with a bleeding disorder. Others may receive care from their primary care physician or a local hematologist.

Inhibitors in Hemophilia

When people with hemophilia A, hemophilia B or Von Willebrand Disease (VWD) use clotting factor replacement products, their immune system can sometimes fight against them by making antibodies. These antibodies are called inhibitors. An inhibitor blocks or destroys the infused replacement factor product, which causes the treatment to not work.

Having an inhibitor makes it harder to stop a bleeding episode. The usual treatment doesn’t work, so health care providers must try different methods and medications. Inhibitors can lead to serious bleeding that could be life-threatening. They may also cause lasting damage to the joints and create difficulties in the social, emotional, and financial parts of a person’s life.

It is estimated that roughly 15 – 20% of people with hemophilia have an inhibitor. Anybody can get an inhibitor regardless of their disease severity (mild, moderate, severe) or age. However, inhibitors are more common in people with hemophilia A.

Von Willebrand Disease

Von Willebrand Disease (VWD), like hemophilia, is a genetic coagulation disorder that affects individuals equally, regardless of sex. It is estimated that roughly 1% of the population—more than 3 million Americans—have VWD, though many with mild symptoms remain undiagnosed.

Symptoms of VWD can include easy bruising, frequent and prolonged nosebleeds, heavy menstrual bleeding, and bleeding after dental procedures or surgeries.

There are several types of VWD, which arise either from a deficiency of Von Willebrand factor in the blood or a qualitative issue with the factor itself. Diagnosing VWD can be complex and is best performed at a specialized Hemophilia Treatment Center (HTC).

Treatment for mild cases of VWD may involve intranasal medication to manage symptoms effectively.

Rare Factor Deficiencies

Blood clotting is a complex process, involving many different proteins, called factors, each of which plays a different role in the blood clotting process. Factor deficiencies are defined by which specific clotting protein in the blood protein is low, missing or doesn’t work properly.

Factor VII (7) Deficiency is the most prevalent of the rare deficiencies. The North American Rare Bleeding Disorders Registry (NARBDR) has documented that FVII deficient patients represent 46% of reported rare bleeding disorder patients (excluding FXI deficiency). 35% of Factor VII (7) deficient patients have documented FVII levels of <20% activity level.
