To the editor: Commercial factor VIII concentrates of pooled plasma origin are being used increasingly in minor and major replacement therapy of hemophilia A bleeding episodes. A case has drawn to our attention that significant isoantibody infusion may occur in replacement and produce acute anemia.
Patient D.H., an 18-year-old man with hemophilia A underwent emergency cricothyrotomy and tracheotomy 15 December 1971 for gross respiratory distress from a cough-produced paralaryngeal hematoma. On the day of surgery the patient received 28 units of group-specific cryoprecipitate, and for 10 days thereafter he was maintained on 18 to 30 cryoprecipitate units/day.
