[A case of pulmonary infiltrates associated with a neutrophil-specific antibody transfusion reactions]
A normovolemic pulmonary edema associated with blood transfusion developed in a 38-year-old woman during gynecological operation. Bilateral pulmonary infiltrates and profound leucopenia (700.microliters-1) were observed. An antibody reactive with the recipient's neutrophils was found in a donor and an antibody reacting with the lymphocytes of the recipient was identified in another donor. Both donors were multiparous women. Respiratory failure was improved with mechanical ventilation but chest X-ray showed pulmonary infiltrates for the next 3 days. The white blood cell count rose to 2900.microliters-1 in the next day, and it took 2 weeks to be normalized. Transient pulmonary infiltrates can be caused by antileukocyte antibodies passively transfused by multiparous donors.
