Studies on a Complex Mechanism for the Activation of Plasminogen by Kaolin and by Chloroform: the Participation of Hageman Factor and Additional Cofactors
Studies on a complex mechanism for the activation of plasminogen by kaolin and by chloroform: the participation of Hageman factor and additional cofactors Derek Ogston, … , Oscar D. Ratnoff, Charles D. Forbes J Clin Invest. 1969;48(10):1786-1801. https://doi.org/10.1172/JCI106145. Research Article As demonstrated by others, fibrinolytic activity was generated in diluted, acidified normal plasma exposed to kaolin, a process requiring Hageman factor (Factor XII). Generation was impaired by adsorbing plasma with glass or similar agents under conditions which did not deplete its content of Hageman factor or plasminogen. The defect could be repaired by addition of a noneuglobulin fraction of plasma or an agent or agents eluted from diatomaceous earth which had been exposed to normal plasma. The restorative agent, tentatively called Hageman factor-cofactor, was partially purified by chromatography and had an apparent molecular weight of approximately 165,000. It could be distinguished from plasma thromboplastin antecedent (Factor XI) and plasma kallikrein, other substrates of Hageman factor, and from the streptokinase-activated pro-activator of plasminogen. Evidence is presented that an additional component may be needed for the generation of fibrinolytic activity in mixtures containing Hageman factor, HF-cofactor, and plasminogen. The long-recognized generation of plasmin activity in chloroform-treated euglobulin fractions of plasma was found to be dependent upon the presence of Hageman factor. Whether chloroform activation of plasminogen requires Hageman factor-cofactor was not determined, but glass-adsorbed plasma, containing Hageman factor and plasminogen, did not generate appreciable fibrinolytic or caseinolytic activity. These studies emphasize the complex nature of the mechanisms which lead to the generation of plasmin in human plasma. -

Factor IX Complex (Human - Bebulin, Profilnine) Reference Number: ERX.SPMN.201 Effective Date: 01/17 Coding Implications Last Review Date: Revision Log
Clinical Policy: Factor IX complex (Human - Bebulin, Profilnine) Reference Number: ERX.SPMN.201 Effective Date: 01/17 Coding Implications Last Review Date: Revision Log See Important Reminder at the end of this policy for important regulatory and legal information. Policy/Criteria It is the policy of health plans affiliated with Envolve Pharmacy SolutionsTM that factor IX complex (Bebulin®, Profilnine®) is medically necessary when the following criteria are met: I. Initial Approval Criteria A. Hemophilia B (must meet all): 1. Prescribed by or in consultation with a hematologist; 2. Diagnosis of hemophilia B; 3. Agent will used for prevention/control of bleeding episodes. Approval duration: 3 months B. Other diagnoses/indications: Refer to ERX.SPMN.16 - Global Biopharm Policy. II. Continued Approval A. Hemophilia B (must meet all): 1. Currently receiving medication via health plan benefit or member has previously met all initial approval criteria. Approval duration: 3 months B. Other diagnoses/indications (must meet 1 or 2): 1. Currently receiving medication via health plan benefit and documentation supports positive response to therapy; or 2. Refer to ERX.SPMN.16 - Global Biopharm Policy. Background Description/Mechanism of Action: Factor IX complex replaces deficient clotting factors including factor X. Hemophilia B, or Christmas disease, is an X-linked recessively inherited disorder of blood coagulation characterized by insufficient or abnormal synthesis of the clotting protein factor IX. Factor IX is a vitamin K-dependent coagulation factor which is synthesized in the liver. Factor IX is activated by factor XIa in the intrinsic coagulation pathway. Activated factor IX (IXa), in combination with factor VII: C, activates factor X to Xa, resulting ultimately in the conversion of prothrombin to thrombin and the formation of a fibrin clot. -
General Considerations of Coagulation Proteins
ANNALS OF CLINICAL AND LABORATORY SCIENCE, Vol. 8, No. 2 Copyright © 1978, Institute for Clinical Science General Considerations of Coagulation Proteins DAVID GREEN, M.D., Ph.D.* Atherosclerosis Program, Rehabilitation Institute of Chicago, Section of Hematology, Department of Medicine, and Northwestern University Medical School, Chicago, IL 60611. ABSTRACT The coagulation system is part of the continuum of host response to injury and is thus intimately involved with the kinin, complement and fibrinolytic systems. In fact, as these multiple interrelationships have un folded, it has become difficult to define components as belonging to just one system. With this limitation in mind, an attempt has been made to present the biochemistry and physiology of those factors which appear to have a dominant role in the coagulation system. Coagulation proteins in general are single chain glycoprotein molecules. The reactions which lead to their activation are usually dependent on the presence of an appropriate surface, which often is a phospholipid micelle. Large molecular weight cofactors are bound to the surface, frequently by calcium, and act to induce a favorable conformational change in the reacting molecules. These mole cules are typically serine proteases which remove small peptides from the clotting factors, converting the single chain species to two chain molecules with active site exposed. The sequence of activation is defined by the enzymes and substrates involved and eventuates in fibrin formation. Mul tiple alternative pathways and control mechanisms exist throughout the normal sequence to limit coagulation to the area of injury and to prevent interference with the systemic circulation.
