Prothrombin complex concentrates. Use in treatment of hemophiliacs with factor VIII inhibitors. 1978

R H Yolken, and M W Hilgartner

The development of factor VIII inhibitors has been a major problem in the management of hemophiliacs. The use of prothrombin complex concentrates (PCC) has been advocated as a method of overcoming this problem. We utilized PCC in the treatment of nine hemophiliac patients who had significant levels of inhibitor. Acute bleeding episodes were successfully treated in all nine patients. Single infusions of PCC were usually adequate for control of joint and soft tissue bleeding episodes, while multiple infusions were usually required for more serious hemorrhages. In addition, programs of repeated infusions were used to heal chronically inflamed joints in three patients. The only side effect of treatment was one episode of asymptomatic elevation of liver function values that resolved spontaneously. There were no thrombotic events associated with the PCC infusions. Therapy with PCC is recommended for the management of hemophiliacs with factor VIII inhibitors.

D011516	Prothrombin	A plasma protein that is the inactive precursor of thrombin. It is converted to thrombin by a prothrombin activator complex consisting of factor Xa, factor V, phospholipid, and calcium ions. Deficiency of prothrombin leads to hypoprothrombinemia.

D002648	Child	A person 6 to 12 years of age. An individual 2 to 5 years old is CHILD, PRESCHOOL.	Children
D002675	Child, Preschool	A child between the ages of 2 and 5.	Children, Preschool,Preschool Child,Preschool Children
D005169	Factor VIII	Factor VIII of blood coagulation. Antihemophilic factor that is part of the factor VIII/von Willebrand factor complex. Factor VIII is produced in the liver and acts in the intrinsic pathway of blood coagulation. It serves as a cofactor in factor X activation and this action is markedly enhanced by small amounts of thrombin.
