Treatments for hemophilia

A.   Treatment With Replacement Therapy

The main treatment for hemophilia is called replacement therapy. Concentrates of clotting factor VIII (for hemophilia A) or clotting factor IX (for hemophilia B) are slowly dripped or injected into a vein. These infusions help replace the clotting factor that's missing or low.

Clotting factor concentrates can be made from human blood. The blood is treated to prevent the spread of diseases, such as hepatitis. With the current methods of screening and treating donated blood, the risk of getting an infectious disease from human clotting factors is very small.

To further reduce the risk, you or your child can take clotting factor concentrates that aren't made from human blood. These are called recombinant clotting factors. Clotting factors are easy to store, mix, and use at home—it only takes about 15 minutes to receive the factor.

You may have replacement therapy on a regular basis to prevent bleeding. This is called preventive or prophylactic (PRO-fih-lac-tik) therapy. Or, you may only need replacement therapy to stop bleeding when it occurs. This use of the treatment, on an as-needed basis, is called demand therapy.

Demand therapy is less intensive and expensive than preventive therapy. However, there's a risk that bleeding will cause damage before you receive the demand therapy.

B.   Other Types of Treatment

·         Desmopressin

Desmopressin (DDAVP) is a man-made hormone used to treat people who have mild hemophilia A. DDAVP isn't used to treat hemophilia B or severe hemophilia A.

DDAVP stimulates the release of stored factor VIII and von Willebrand factor; it also increases the level of these proteins in your blood. Von Willebrand factor carries and binds factor VIII, which can then stay in the bloodstream longer.

DDAVP usually is given by injection or as nasal spray. Because the effect of this medicine wears off if it's used often, the medicine is given only in certain situations. For example, you may take this medicine prior to dental work or before playing certain sports to prevent or reduce bleeding.

·         Antifibrinolytic Medicines

Antifibrinolytic medicines (including tranexamic acid and epsilon aminocaproic acid) may be used with replacement therapy. They're usually given as a pill, and they help keep blood clots from breaking down.

These medicines most often are used before dental work or to treat bleeding from the mouth or nose or mild intestinal bleeding.

·         Gene Therapy

Researchers are trying to find ways to correct the faulty genes that cause hemophilia. Gene therapy hasn't yet developed to the point that it's an accepted treatment for hemophilia. However, researchers continue to test gene therapy in clinical trials.

·         Treatment of a Specific Bleeding Site

Pain medicines, steroids, and physical therapy may be used to reduce pain and swelling in an affected joint. Talk with your doctor or pharmacist about which medicines are safe for you to take.
