Patients whose antibodies react with a donor’s white blood cells present febrile non-hemolytic reactions as well. This is not an uncommon medical situation and has been studied for a long time already. Some scientific studies have shown that certain type of thalassemic patients often get a fever when they get a blood transfusion due to their antibodies working against HLA.
