How is Hemophilia treated?

There is no current way to prevent hemophilia from manifesting in a person, as it is an inherited disease. Gene therapy may be viable in the future, but at the moment it is still a very experimental and unproven treatment.  Hypothetically, a person who is a know carrier of the hemophilia gene could terminate their pregnancy after screening their unborn child for the disorder.

The most popular method of treating Hemophiliacs is replacement therapy. For replacement therapy, depending on which Hemophilia the individual has, A or B, a clotting factor is infused in the vein – to substitute for the missing or low factor in the person.  Gene therapy is not an option in humans yet but positive results have been obtained in mice VandenDriessche et al. (1999).

Individuals can also do preventative exercise to increase flexibility, and strengthen their joints and muscles to curtail any effects of damaging bleeding that could occur.

Here is a video which showing the ease of living with and treating Hemophilia that modern Hemophiliacs possess. The key to living with Hemophilia is risk management and being vigilant of what is going on with an individuals body.
