<abstract xmlns="http://www.w3.org/1999/xhtml"><p>A 54-year-old female patient with a history of chronic liver disease and portal hypertension was admitted for an elective cholecystectomy. Preoperative evaluation revealed a prolonged prothrombin time of 17.4 seconds (control 12 to 15.5 seconds). Six units of fresh frozen plasma (FFP) were prescribed after failure of correction of the coagulopathy with intravenous vitamin K (10 mgs). During infusion of the fifth unit of FFP, the patient became acutely dyspneic. Arterial blood gas analysis revealed marked hypoxemia (PO<sub>2</sub> 6.58 kPa) and the chest X-ray showed new diffuse bilateral alveolar infiltrates. The patient remained hypoxemic with unstable oxygen saturations over the following 7 days, during which time she required 60 to 100 percent oxygen administered by face mask. Intravenous methylprednisolone (200 mgs) was given for 5 days. Mechanical ventilation was not required. The lung infiltrates gradually cleared over 3 to 4 days and the patient showed clinical improvement after 1 week. Four of the donors of the implicated units of plasma were female and all had a history of pregnancy. Two donors had HLA class I antibodies and two had granulocytespecific antibodies detectable in their serum. In crossmatch studies, granulocyte-reactive antibodies from two donors bound to granulocytes from the patient, which suggested that these antibodies were clinically relevant.
