    Abstract:
    BACKGROUND: To reduce the risk of transfusion-related acute lung injury (TRALI), plasma products are mainly made from male donors in some countries because of the lower possibility of alloimmunization; other countries are considering this policy. The advantage of male-only fresh-frozen plasma (FFP) should be examined in a prospective case-control study. STUDY DESIGN AND METHODS: This study compared pulmonary function after the transfusion of FFP derived from either male donors only (FFP-male) or mixed donors (FFP-mixed) in informed surgical patients treated at a tertiary university hospital in Japan. The factors contributing to pulmonary distress (PD) after transfusion were then statistically examined. RESULTS: Eighty-two patients participated in this study (FFP-male, n = 55; FFP-mixed, n = 27). Nineteen patients developed PD (PaO(2)/FiO(2) ratio [P/F] < 300) within 6 hours after transfusion: seven had congestive pulmonary edema (transfusion-associated circulatory overload), five had permeability pulmonary edema (possible TRALI), and seven had no apparent pulmonary edema. A multivariate logistic regression analysis revealed that the use of cardiopulmonary bypass and preoperative liver dysfunction were significantly associated with a P/F of less than 300 (odds ratios [ORs], 8.95 [p = 0.004] and 6.54 [p = 0.005], respectively), while the use of FFP-male was significantly associated with the absence of PD (OR, 0.219; p = 0.022). All the patients with possible TRALI had received either white blood cell or granulocyte antibody-positive FFP. The lysophosphatidylcholine level was not correlated with PD. CONCLUSIONS: Our data suggests that the use of FFP derived from male donors may be advantageous for posttransfusion pulmonary function, although PD is also determined by background characteristics.
