[PPSB].

Abstract

PPSB, the plasma derivative which contains the vitamin K-dependent clotting factors, was first produced in 1959 at the Centre National de Transfusion Sanguine in Paris under the leadership of Jean-Pierre Soulier. Today over 20 such products are manufactured around the world. All production methods take advantage of the common adsorption and elution properties of all the vitamin K-dependent clotting factors due to the presence of gamma carboxy residues. Although the clinical use of PPSB has been extended to all congenital and acquired deficiencies of the vitamin K-dependent clotting factors and more recently to treat hemorrhagic episodes of hemophilia A patients with antibody to Factor VIII, the major clinical indication remains hemophilia B. The major complication associated with the use of PPSB is the occurrence of viral diseases, particularly non-A, non-B hepatitis of unknown etiology and specifically associated with the use of PPSB is the occurrence in some patients of thromboembolic complications. Current research is oriented toward the production of a safer product.
