Importance of the field: Hemophilia management requires replacement of the deficient clotting factor. Inhibitor development complicates treatment, and the implementation of and adherence to prophylaxis, considered the standard of care for severe hemophilia, is hampered by the high cost and the need for frequent intravenous infusions. New, less expensive therapies are needed to reduce morbidities, enhance convenience and improve outcomes. Areas covered in this review: We conducted a search of the Medline database from 1990 to 2010 for English language articles pertaining to hemophilia drug therapy. More than 4000 citations were obtained and examined for topic relevance. Additionally, proceedings from the American Society of Hematology, International Society on Thrombosis and Hemostasis, World Federation of Hemophilia, National Hemophilia Foundation and European Association for Haemophilia and Allied Disorders and the ClinicalTrials.gov website were reviewed for relevant publications and information. What the reader will gain: This article summarizes current research efforts focused on developing less immunogenic and more potent and/or longer-acting clotting factor concentrates that uniquely promote hemostasis, are more affordable and do not require intravenous administration. Take home message: The availability of orally administered clotting factors will truly transform the lives of hemophilia patients and their families and caregivers.

A deficiency of blood coagulation factor IX inherited as an X-linked disorder. (Also known as Christmas Disease, after the first patient studied in detail, not the holy day.) Historical and clinical features resemble those in classic hemophilia (HEMOPHILIA A), but patients present with fewer symptoms. Severity of bleeding is usually similar in members of a single family. Many patients are asymptomatic until the hemostatic system is stressed by surgery or trauma. Treatment is similar to that for hemophilia A. (From Cecil Textbook of Medicine, 19th ed, p1008)
The classic hemophilia resulting from a deficiency of factor VIII. It is an inherited disorder of blood coagulation characterized by a permanent tendency to hemorrhage.
A hereditary deficiency of blood coagulation factor XI (also known as plasma thromboplastin antecedent or PTA or antihemophilic factor C) resulting in a systemic blood-clotting defect called hemophilia C or Rosenthal's syndrome, that may resemble classical hemophilia.
