Differentiating pulmonary transfusion reactions using recipient and transfusion factors.

ABSTRACT: It is increasingly recognized that recipient risk factors play a prominent role in possible transfusion-related acute lung injury (pTRALI) and transfusion-associated circulatory overload (TACO). We hypothesized that both transfusion and recipient factors including natriuretic peptides could be used to distinguish TRALI from TACO and pTRALI.We performed a post hoc analysis of a case-control study of pulmonary transfusion reactions conducted at the University of California at San Francisco and Mayo Clinic, Rochester. We evaluated clinical data and brain natriuretic peptides (BNP) levels drawn after transfusion in patients with TRALI (n?=?21), pTRALI (n?=?26), TACO (n?=?22), and controls (n?=?24). Logistic regression and receiver operating characteristics curve analyses were used to determine the accuracy of clinical and biomarker predictors in differentiating TRALI from TACO and pTRALI.We found that pTRALI and TACO were associated with older age, higher fluid balance, and elevated BNP levels relative to those of controls and TRALI. The following variables were useful in distinguishing cases of pTRALI and TACO from TRALI: age more than 70 years, BNP levels more than 1000 pg/mL, 24-hour fluid balance of more than 3 L, and a lower number of transfused blood components. Using the above variables, our logistic model had a 91% negative predictive value in the differential diagnosis of TRALI.Models incorporating readily available clinical and biomarker data can be used to differentiate transfusion-related respiratory complications. Additional studies examining recipient risk factors and the likelihood of TRALI may be useful in decision making regarding donor white blood cell antibody testing.

Project description:ObjectiveDonor blood transfusion has been identified as a potential risk factor for primary graft dysfunction and by extension early mortality. We sought to define the contributing risk of donor transfusion on early mortality for lung transplant.MethodsDonor and recipient data were abstracted from the Organ Procurement and Transplantation Network database updated through June 30, 2014, which included 86,398 potential donors and 16,255 transplants. Using the United Network for Organ Sharing 4-level designation of transfusion (no blood, 1-5 units, 6-10 units, and >10 units, massive), we analyzed all-cause mortality at 30-days with the use of logistic regression adjusted for confounders (ischemic time, donor age, recipient diagnosis, lung allocation score and recipient age, and recipient body mass index). Secondary analyses assessed 90-day and 1-year mortality and hospital length of stay.ResultsOf the 16,255 recipients transplanted, 8835 (54.35%) donors received at least one transfusion. Among those transfused, 1016 (6.25%) received a massive transfusion, defined as >10 units. Those donors with massive transfusion were most commonly young trauma patients. After adjustment for confounding variables, donor massive transfusion was associated significantly with an increased risk in 30-day (P = .03) and 90-day recipient mortality (P = .01) but not 1-year mortality (P = .09). There was no significant difference in recipient length of stay or hospital-free days with respect to donor transfusion.ConclusionsMassive donor blood transfusion (>10 units) was associated with early recipient mortality after lung transplantation. Conversely, submassive donor transfusion was not associated with increased recipient mortality. The mechanism of increased early mortality in recipients of lungs from massively transfused donors is unclear and needs further study but is consistent with excess mortality seen with primary graft dysfunction in the first 90 days posttransplant.
