Routine prophylaxis and perioperative management of bleeding in patients with congenital factor XIII deficiency; designated an orphan drug by FDA for treatment of congenital factor XIII deficiency.

Initial FDA-labeled use based on trough factor XIII levels (5–20%) as a surrogate measure of efficacy; clinical benefit (i.e., prevention of bleeding episodes) established in a postmarketing study.

Prophylactic therapy with factor XIII concentrates is recommended in all patients with severe (<1% factor XIII activity) deficiency; considered current standard of care.

Currently available factor XIII concentrates in the US include a plasma-derived (Corifact) and a recombinant (Tretten) preparation. Some experts recommend preferential use of recombinant preparations because of their potentially superior safety profile with respect to pathogen transmission. (See Risk of Transmissible Agents in Plasma-derived Preparations under Cautions.) When selecting an appropriate factor XIII preparation, consider characteristics of each clotting factor concentrate in addition to individual patient variables.
