The term Transfusion-Related Acute Lung Injury (TRALI) was coined in 1985. It is a relatively rare, life-threatening clinical syndrome characterized by acute respiratory failure and non-cardiogenic pulmonary edema during or following a blood transfusion. Although its true incidence is unknown, a rate 1 out of every 5000 transfusions has been quoted. TRALI has been the most common cause of trans...
Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related mortality. Antibodies to HNA-3a are commonly implicated in TRALI. We hypothesized that HNA-3a antibodies prime neutrophils (PMNs) and cause PMN-mediated cytotoxicity through a two-event pathogenesis. Isolated HNA3a or HNA-3a PMNs were incubated with plasma containing HNA-3a antibodies implicated in TRALI, ...
Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related mortality. To determine TRALI incidence by prospective, active surveillance and to identify risk factors by a case-control study, 2 academic medical centers enrolled 89 cases and 164 transfused controls. Recipient risk factors identified by multivariate analysis were higher IL-8 levels, liver surgery, chro...
BACKGROUND Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related fatality reported to the Food and Drug Administration. Donor screening may reduce TRALI risk. This study sought to compare the efficacy and safety of different TRALI risk-reduction strategies at a hospital-based donor center. STUDY DESIGN AND METHODS Samples from 1053 donors who answered quest...
BACKGROUND AND OBJECTIVES Transfusion-related acute lung injury (TRALI) is often caused by antibodies against human neutrophil alloantigen-2 (HNA-2) and HNA-3a. Neutrophil aggregation is considered as a major cause of TRALI, but little is known about how HNA antibodies initiate this process. We explored mechanisms involved in neutrophil aggregation induced by HNA-2 and HNA-3a antibodies. MATE...
We report two separate episodes of transfusion-related acute lung injury (TRALI) in two thalassaemia patients who received red blood cell transfusions from the same multiparous donor. Both cases had the same symptomatology and occurred within 60 minutes of transfusion. The patients presented dyspnoea, sweating, fatigue, dizziness, fever, and sense of losing consciousness. The chest x-ray showed...
objective(s):therapies with high levels of oxygen are commonly used in the management of critical care. however, prolonged exposure to hyperoxia can cause acute lung injury. although oxidative stress and inflammation are purported to play an important role in the pathogenesis of acute lung injury, the exact mechanisms are still less known in the hyperoxic acute lung injury (hali). materials a...
