title: Evaluation of off-label recombinant activated factor VII for multiple indications in children.
abstract: Despite a paucity of safety and efficacy data, the use of recombinant activated factor VII in children for off-label indications has now surpassed its use in hemophilia. A retrospective chart review was conducted of 46 subjects (age, 6.7 +/- 6 years; weight, 26 +/- 20 kg) who received recombinant activated factor VII for nonhemophiliac indications between January 1, 2004, and September 1, 2005. Indications for use included prevention (n = 6) or treatment (n = 40) of bleeding due to general surgery, hepatic failure, gastrointestinal bleeding, severe traumatic brain injury, bone marrow transplant, cardiac, acetaminophen overdose, and multiorgan system failure. Decreases in prothrombin time, partial thromboplastin time, and international normalized ratio were observed. No inappropriate thrombotic events were noted. Administration of recombinant activated factor VII was associated with a reduction in coagulation markers without obvious adverse thrombotic events at cost of $4189 per dose. These findings should be confirmed in a prospective trial.
