Vol. 19, no 6, p. 882-886 Keywords [en] 1999-04-03 Request PDF | Extending the pharmacokinetic half-life of coagulation factors by fusion to recombinant albumin | The prophylactic treatment of haemophilia B and the management of haemophilia A or B Synthetic liver failure: Since coagulation factors, including factor VII, are produced in the liver, the PT could be prolonged in liver failure, however usually the APTT is also prolonged. Inhibitors of factor VII: Antibody inhibitors of factor VII have not been reported in animals. Factor VII has the shortest half-life of all of the clotting factors, estimated to be 6 hours. Severe factor VII deficiency is the most common of the nonhemophilic coagulation factor deficiencies (Table 137.1), with an estimated prevalence of 1 in 500,000 persons. The onset of alloantibodies inactivating the infused coagulation factor is the main problem in hemophilia patients rendering replacement therapies ineffective; another disadvantage is the short half‐life of the infused clotting factors with the need for multiple and frequent infusions to manage a bleeding episode.

The tissue factor and contact activation  In the coagulation cascade, chemicals called clotting factors (or coagulation factors) form, clots would form spontaneously, a condition not consistent with life. The prolongation of PT depends on reductions in three of the vitamin K dependent clotting factors (II, VII and X). Changes in the PT noted in the first few days of vitamin K antagonist (VKA) therapy are primarily due to reductions in factor VII which has the shortest half-life of 6 hours.

Factors II, VII, IX, and X are vitamin-K-dependent and require vitamin K in order to undergo post-translational gamma carboxylation. Although the half-life of Factor VIIa of 2 hours is comparatively long for an activated coagulation factor (which is, for other activated coagulation factors more in the order of minutes due to the irreversible inhibition by serpins like antithrombin III) this nevertheless constitutes a severe drawback for the therapeutic use of Factor VIIa, as it leads to the need of multiple i.v. injections Moreover, the short half-life of factor VII requires FFP infusion every 6 to 12 hours in patients with INR greater than 1.5. FFP is given (12 to 15mL/kg) before liver biopsy, but there is no Extended half life factor IX products have an increase in half life between 3 to 5 times that of standard half life FIX products.
