Hemophilia 4

Hemophilia is the best known of hemorrhagic disorders. When a person has hemophilia, the blood does not clot properly and bleeding persists. The people who have hemophilia are called hemophiliacs or bleeders. Bleeding disorders, such as hemophilia, result from a disruption of the body's process of how blood clots are formed. The coagulation process involve platelets as well as plasma proteins called clotting factors. Clotting begins when platelets stick to the site of an injury to a blood vessel. The proteins in the plasma that cause blood to clot is absent.

Hemophilia is named from a Greek word meaning " fond of blood". There are two types of hemophilia. Hemophilia A, which is the most common and is also called classic hemophilia. Hemophilia B or Christmas disease, named after the first patient diagnosed and treated with hemophilia B. Hemophilia B lacks AHF (antihemophilic factor). About 85% of hemophiliacs have classic or hemophilia A. Hemophilia A's blood lacks the clotting factor eight. The rest of the 85% have Christmas, which lacks clotting factor nine. An extremely small number of hemophiliacs lack yet another kind of clotting factor.

Both A and B forms have also been called the royal disease. Hem


There is special treatment for hemophiliacs. Already the drug desmopressin was brought to your attention. This drug helps stop bleeding by stimulating the release factor eight and making blood contract. If you have hemophilia B or a more severe case of hemophilia A, bleeding episodes may stop only after the missing clotting factors are replaced by infusion. These clotting factors are derived from donated human blood and are supplied as purification concentrates ( a clotting factor concentrate derived from donated blood). During the 1980's, hundreds of hemophiliacs became infected with the AIDS virus (Acquired Immune Deficiency Syndrome) after receiving treatments of clotting factor contaminated with the virus. More than half of those infected have died of AIDS. Since 1985, the clotting factor concentrates were treated to prevent the transmission of AIDS and this is greatly increased the safety of treatments with clotting factor. With special training through a physician or regional hemophilia center, a hemophiliac can learn to infuse desmopressin, DDAVP, or some of these blood products by himself as soon as he shows some signs of bleeding. Don't use medications that might worsen bleeding, such as aspirin. Thanks to modern blood bank techniques, quantities of whole blood can be made readily available. Bed rest and hospitalization may also be recommended by a doctor.

ophilia was inherited by decedents of England's Queen Victoria and introduced into the royal houses of Spain, Germany, and Russia.

A physician can diagnose hemophilia by using specialized laboratory tests to measure the clotting activity of factors eight and nine, or other factors for that matter. Further investigating can occasionally turn up the condition in other members of the family. The way current medical tre
