How Hemophilia Is Inherited
Hemophilia is a rare disorder where the person is unable to stop bleeding due to a lack of certain blood clotting factors. It’s a genetic disease that’s passed down through the X chromosome. Almost all people with hemophilia are male, however, women can be carriers of the disease. MORE: Explaining hemophilia carriers…
The severity levels of hemophilia are determined by the level of residual/remaining clotting factor (factor VIII or factor IX) activity in the patient’s blood, which is denoted by the percentage of factor activity in the blood (or international units per ml of blood – IU/ml). According to the World Federation of Hemophilia,…
A look at how FVIII/FIX deficiency contributes to variable disease severity and provides the biologic foundation for modern hemophilia therapies.
Hemophilia is classified as mild, moderate, or severe, depending on the level of clotting factor in the blood. About 70% of those with hemophilia have the severe form. The most important life-threatening complications of the disease are bleeding in the skull and hemorrhages in soft tissue around airways or other…
What About Hemophilia?
Mr. Man started coughing on Friday and grew much worse by Saturday. My boy struggled with flu-like symptoms all weekend. We thought that by giving him allergy meds and cough suppressants, he would recover and be well for school on Monday. No such luck. The medicines wouldn’t work,…
Prophylaxis and on-demand treatment for hemophilia: How doctors decide
Fact-Checked By Joana Carvalho, PhD
After a hemophilia diagnosis, people typically work with their care team to develop a tailored treatment plan. This will likely involve considering both preventive (prophylactic) and on-demand hemophilia treatment options. People with hemophilia are susceptible to excessive or prolonged bleeding episodes because certain blood clotting factors are dysfunctional…
Although no cure for hemophilia is currently available, a number of therapies can be used to control bleeding and other symptoms. These treatments can substantially increase life expectancy by lowering the risk of life-threatening complications such as bleeding in the brain, especially in people with severe hemophilia.
