Development of Antibodies to Bovine and Human Factor V in Two Children After Exposure to Topical Bovine Thrombin

Abstract

Pediatric patients exposed to topical bovine thrombin, particularly in the setting of cardiac surgery, are at risk for the development of antibodies to bovine thrombin and factor V. This may also result in apparent but spurious depletion of other coagulation factors. These antibodies may cross-react with human coagulation factors, particularly factor V, resulting in clinical bleeding.
