Transfusion-related acute lung injury (TRALI) has been implicated with use of almost all types of blood products that contain variable amounts of plasma. Even though the reported incidence of TRALI is rare, its overall occurrence is thought to be more common, as less severe cases remain unreported. More TRALI cases are unrecognized and misdiagnosed due to lack of suspicion and absence of appropriate investigation. There are exceedingly rare reports of TRALI during plasma exchange despite the fact that liters of plasma may be used for replacement during a single procedure. We describe a mild case of TRALI during plasma exchange for thrombotic thrombocytopenic purpura in a 56-year-old woman, status post autologous hematopoietic stem cell transplant for non-Hodgkin's lymphoma. She developed severe rigors, peripheral cyanosis, hypoxia, and a transient diffuse pulmonary infiltrate. Of the 10 U of plasma used, one was from a multiparous female donor with HLA antibodies reactive with patient's granulocytes in immunofluorescence and agglutination assays. This case emphasizes the fact that the physicians and apheresis staff should consider TRALI in the differential diagnosis for patients developing respiratory distress during or soon after the procedure. Diagnosing TRALI has implications not only for the plasma exchange recipient, but also for the management of donors found to have leukocyte antibodies.

Transfusion-related acute lung injury (TRALI) is a transfusion reaction that is often under recognized and underreported. Implications for diagnosis not only influence treatment considerations but also extend to donor selection, donor deferral and ultimately the safety of the final blood product. We report a case of a previously well 19-year-old female who presented a one week history of flu-like symptoms and mucosal bleeding. Laboratory results confirmed the diagnosis of thrombotic thrombocytopaenia purpura (TTP) and she was commenced on plasma exchange. During her second day of plasma exchange, she developed dyspnoea and rigors. Examination and investigation findings were consistent with a clinical diagnosis of TRALI. Granulocytes immunofluorescent test (GIFT - flow cytometry) was performed and cross reactivity was demonstrated between the patient's granulocytes and plasma from one of the nine donor fresh frozen plasma (FFP) packs. She made a full recovery. TRALIa accounts for 7% of all adverse events reported in the Serious Hazards of Transfusion (SHOT) database and has a mortality rate between 5-25%. Apheresis patients are a particularly vulnerable group of patients where clinical recognition and rapid laboratory confirmation of TRALI is imperative to minimize the risk of further patient exposure to donor granulocyte or human leukocyte antigen (HLA) antibodies. The provision of plasma from male donors may additionally reduce exposure. On a wider scale, rapid donor identification and deferral maintains the safety of the national blood supply.
