Entry term(s) deficiencia del factor IX
enfermedad de Christmas
Scope note: Déficit del factor IX de la coagulación sanguínea, heredado como trastorno vinculado al cromosoma X (conocido también como enfermedad de Christmas, por el primer paciente estudiado en detalle, no por el día de navidad). Tanto el desarrollo como los datos clínicos se asemejan a los de la hemofilia clásica (HEMOFILIA A), pero los pacientes presentan menos síntomas. La gravedad de las hemorragias suele ser similar en los miembros de una misma familia. Muchos pacientes permanecen asintomáticos hasta que se produce una especial demanda del sistema hemostático con motivo de una intervención quirúrgica o un trauma. El tratamiento es similar al de la hemofilia A.

Scope note: 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)
