Abstract BACKGROUND: TRALI is a serious adverse effect of blood transfusion. There is evidence that the condition is underrecognized and underreported. STUDY DESIGN AND METHODS: This study was an observational study carried out in a single hospital. RESULTS: Eleven cases of TRALI were recognized over 12 years. In 10 cases the implicated donor unit was FFP and in 1 case uncertain. All implicated donors were parous women. In 4 cases the presumed causative antibodies were to an HLA class II antigen only. Specific anti-neutrophil antibodies, possibly causative, were detected in 1 case only. Ten of the 11 cases required mechanical ventilatory support. Five persons died as a result of the TRALI. The observed incidence of TRALI caused by FFP is 1 in 7900 units transfused. CONCLUSION: TRALI is the most common serious adverse effect of blood transfusion in our hospital. Antibodies to HLA class II antigens should be looked for routinely when investigating a possible case of TRALI.
