An Acquired Inhibitor to Factor X In a Pediatric Patient with Extensive Burns

PURPOSE: An acquired inhibitor to factor X is an uncommon clinical finding in the pediatric population. We report the development of this type of inhibitor in a pediatric patient with extensive burns. PATIENTS AND METHODS: The patient's clinical course was complicated by persistent blood loss from the burn site. RESULTS: Characterization of the inhibitor demonstrated that it bound to the light chain of factor X. CONCLUSIONS: The inhibitor disappeared after treatment with i.v. immunoglobulin.
