How do you treat it?
• replacement therapy: injecting concentrations of clotting factor VIII (for hemophilia A) or clotting factor IX (for hemophilia B) into the vein• desmopressin (DDAVP): man-made hormone given as an injection or nasal spray that stimulates the release of stored factor VIII• antifibrinolytic medicines: help keep blood clots from breaking down
• disorder that slows down the blood clotting process• two major types: hemophilia A and hemophilia B• hemophilia A: gene mutation (insertion, substitution, or missing) of F8 gene, deficiency in the protein coagulation factor VIII• hemophilia B: gene mutation (insertion, substitution, or missing) in the F9 gene, deficiency in protein coagulation factor IX
• inherited in an x-linked recessive pattern• acquired hemophilia (not by genetics): body makes antibodies that attack and disable coagulation factor VIII
• spontaneous bleeding• prolonged bleeding after injury• many large bruises• swelling of joints caused by internal bleeding• nosebleeds without a cause
