Abstract
BACKGROUND AND OBJECTIVES To explore transfusion-related acute lung injury (TRALI) induced by human leucocyte antigen (HLA)-II antibodies, and to analyse antibody typing and source. MATERIALS AND METHODS We retrospectively analysed the clinical symptoms and signs of two leukaemia patients with suspected TRALI from the same female donor. HLA phenotyping was performed on the two patients, the platelet donor, her husband and her two children. The HLA and human neutrophil antigen antibodies in the donor's plasma were identified. RESULTS The clinical manifestations of two leukaemia patients were those of TRALI, and we treated them with timely ventilator support. A high titre of HLA-II antibodies was in the plasma of the platelet donor. The antibodies were directed at HLA-DRB3*03:01, HLA-DRB1*09:01, HLA-DRB1*12:02, HLA-DRB3*01:01 and HLA-DRB1*12:01:01G, which were specific to the HLA antigens of the two patients. High-resolution HLA genotyping suggested that the donor's HLA-II antibodies were derived from immune stimulation by the husband's antigens during pregnancy. CONCLUSIONS This study described two cases of TRALI caused by HLA-II antibodies from the same female donor. Appropriate management of blood donors with a history of multiple pregnancies is crucial.

Abstract
Transfusion related acute Lung injury (TRALI) though a serious blood transfusion reaction with a fatality rate of 5-25 % presents with acute respiratory distress with hypoxaemia and noncardiac pulmonary oedema within 6 h of transfusion. In non fatal cases, it may resolve within 72 h or earlier. Although reported with an incidence of 1:5000, its true occurrence is rather unknown. Pathogenesis is believed to be related to sequestration and adhesion of neutrophils to the pulmonary capillary endothelium and its activation leading to its destruction and leaks. The patient's underlying condition, anti-neutrophil antibody in the transfused donor plasma and certain lipids that accumulate in routinely stores blood and components are important in its aetiopathogenesis. Patient's predisposing conditions include haematological malignancy, major surgery (especially cardiac), trauma and infections. The more commonly incriminated products include fresh frozen plasma (FFP), platelets (whole blood derived and apheresis), whole blood and Packed RBC. Occasional cases involving cryoprecipitate and Intravenous immunoglobulin (IVig) have also been reported. We present a 15 year single institution experience of TRALI, during which we observed 9 cases among 170,871 transfusions, giving an incidence of 1:19,000. We did not encounter cases of haematological malignancy or cardiac surgery in our TRALI patients. Among the blood products, that could be related to TRALI in our patients included solitary cases receiving cryoprecipitate, IVIg, and recombinant Factor VII apart from platelets and FFP. All patients were treated with oxygen support. Six patients required mechanical ventilation. Off label hydrocortisone was given to all patients. There were no cases of fatality among our patients.

Abstract
Transfusion-related acute lung injury (TRALI) is the most common cause of serious morbidity and mortality due to hemotherapy. The pathogenesis is the result of two events: the first related to the recipient's clinical condition, predisposing to acute lung injury (ALI) through neutrophil or polymorphonuclear leukocyte sequestration, and the second being the infusion of antibodies or mediators that activate these adherent polymorphonuclear neutrophils, resulting in endothelial damage, capillary leak and ALI. TRALI is most prevalent in the critically ill, although many of these cases are termed ALI. Although mitigation strategies, such as the use of male-only plasma, have decreased the number of TRALI cases and deaths, TRALI still occurs. This review will detail the pathophysiology of TRALI, provide insight into newer areas of research and critically assess current practices to mitigate TRALI and improve transfusion safety.

Abstract
BACKGROUND AND OBJECTIVES Severe transfusion-related acute lung injury (TRALI) events have been linked to donor-derived neutrophil antibodies. The journey to developing mass donor neutrophil antibody screening platforms is challenged by the fragility of neutrophils and their unique-specific antigenic characteristics. MATERIAL AND METHODS This article critically evaluates the capabilities and potential of five emerging antibody screening platforms designed to detect neutrophil reactive antibodies relevant to TRALI. They are compared with established neutrophil serological methods. RESULTS Data from two recombinant antigen platforms and a method using human neutrophil antigens-expressing KY cells indicated high specificity. Two mixed cellular flow cytometric assays have the advantage of presenting native conformation of the human polymorphonuclear neutrophil antigenic epitopes. CONCLUSIONS To date, the number and specificity of test sera applied to each platform is small. This needs to be substantially increased and further rigorous serological evaluation is yet needed to compare the sensitivity and specificity limits of each new platform with classical methods. With a limited world supply of TRALI-relevant test sera, a collaborative effort of laboratories with neutrophil and TRALI investigation expertise is required.

Abstract
The neutrophil is an essential component of the innate immune system, and its function is vital to human life. Its production increases in response to virtually all forms of inflammation, and subsequently, it can accumulate in blood and tissue to varying degrees. Although its participation in the inflammatory response is often salutary by nature of its normal interaction with vascular endothelium and its capability to enter tissues and respond to chemotactic gradients and to phagocytize and kill microrganisms, it can contribute to processes that impair vascular integrity and blood flow. The mechanisms that the neutrophil uses to kill microorganisms also have the potential to injure normal tissue under special circumstances. Its paradoxical role in the pathophysiology of disease is particularly, but not exclusively, notable in seven circumstances: 1) diabetic retinopathy, 2) sickle cell disease, 3) TRALI, 4) ARDS, 5) renal microvasculopathy, 6) stroke, and 7) acute coronary artery syndrome. The activated neutrophil's capability to become adhesive to endothelium, to generate highly ROS, and to secrete proteases gives it the potential to induce local vascular and tissue injury. In this review, we summarize the evidence for its role as a mediator of tissue injury in these seven conditions, making it or its products potential therapeutic targets.

Abstract
STUDY DESIGN This is a single-center retrospective case-control study of 7 transfusion-related acute lung injury (TRALI) cases and 28 controls in the pediatric spinal surgery population. OBJECTIVE To determine the association between maternal transfusion and risk of TRALI in pediatric spinal surgery patients. SUMMARY OF BACKGROUND DATA Previous studies support a "2-hit" model for the pathogenesis of TRALI-activation and sequestration of neutrophils in the pulmonary vasculature followed by transfusion of a biologic response modifier such as antileukocyte antibodies. Maternal donation of blood products is a potential risk factor for TRALI because of the development of antileukocyte antibodies during pregnancy. Until now there have been no studies specifically addressing the risk of TRALI following maternal transfusions. METHODS This is a retrospective case-control study of 7 TRALI cases with 4 controls per case, matched by strata for volume of plasma transfused. All cases identified by the Transfusion Biology and Medicine Specialized Center of Clinically Oriented Research with a TRALI diagnosis were eligible for inclusion. Electronic medical records and operative notes were reviewed to obtain demographic data, diagnosis, surgical approach, and number of spine levels for each operation. RESULTS An increased prevalence of maternal blood transfusion was found among the TRALI cases compared with the control cases: 43% (3 of 7) versus 7% (2 of 28), P = 0.044. There were otherwise no statistical differences between the groups, including age, gender, surgical approach, number of spinal levels, or type of blood product transfused. CONCLUSION Pediatric patients undergoing spinal surgery may be at increased risk for the development of TRALI following the transfusion of maternal blood products. Accordingly, we recommend that directed donation of maternal blood products should be avoided in this population. This study also found that TRALI may be underrecognized and underreported to the transfusion service.

Abstract
Abstract
Transfusion-related acute lung injury (TRALI) is a serious complication of transfusion and has been ranked as one of the leading causes of transfusion-related fatalities. Nonetheless, many details of the immunopathogenesis of TRALI, particularly with respect to recipient factors are unknown. We used a murine model of antibody-mediated TRALI in an attempt to understand the role that recipient lymphocytes might play in TRALI reactions. Intravenous injection of an IgG2a antimurine major histocompatibility complex class I antibody (34-1-2s) into BALB/c mice induced moderate hypothermia and pulmonary granulocyte accumulation but no pulmonary edema nor mortality. In contrast, 34-1-2s injections into mice with severe combined immunodeficiency caused severe hypothermia, severe pulmonary edema, and approximately 40% mortality indicating a critical role for T and B lymphocytes in suppressing TRALI reactions. Adoptive transfer of purified CD8+ T lymphocytes or CD4+ T cells but not CD19+ B cells into the severe combined immunodeficiency mice alleviated the antibody-induced hypothermia, lung damage, and mortality, suggesting that T lymphocytes were responsible for the protective effect. Taken together, these results suggest that recipient T lymphocytes play a significant role in suppressing antibody-mediated TRALI reactions. They identify a potentially new recipient mechanism that controls the severity of TRALI reactions.

Abstract
Transfusion-related acute lung injury (TRALI) is the major cause of transfusion related morbidity and mortality, world wide. Efforts to reduce or eliminate this serious complication of blood transfusion are hampered by an incomplete understanding of its pathogenesis. Currently, TRALI is thought to be mediated by donor alloantibodies directed against host leukocytes or the result of 2 distinct clinical events. For both proposed mechanisms, the neutrophil is the key effector cell. This article reviews TRALI pathophysiology, explores the role of the neutrophil, details practical information for appropriate diagnosis and promotes further studies into the pathogenesis of TRALI.

Abstract
Transfusion-related acute lung injury (TRALI) is the most common cause of serious morbidity and mortality due to hemotherapy. Although the pathogenesis has been related to the infusion of donor antibodies into the recipient, antibody negative TRALI has been reported. Changes in transfusion practices, especially the use of male-only plasma, have decreased the number of antibody-mediated cases and deaths; however, TRALI still occurs. The neutrophil appears to be the effector cell in TRALI and the pathophysiology is centered on neutrophil-mediated endothelial cell cytotoxicity resulting in capillary leak and ALI. This review will detail the pathophysiology of TRALI including recent pre-clinical data, provide insight into newer areas of research, and critically assess current practices to decrease it prevalence and to make transfusion safer.

Abstract
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.

Abstract
Transfusion-related acute lung injury (TRALI) is increasingly recognized as a major complication of transfusion therapy; it was the leading cause of transfusion-related fatalities in the United States in 2003. Most cases of TRALI that have been reported are in adult patients. We present two cases of TRALI that occurred in children and review the existing literature of paediatric TRALI. The paediatric TRALI case reports highlight two laboratory findings that can help in the diagnosis of TRALI: transient leucopenia and an elevated pulmonary oedema fluid/plasma protein ratio. These two simple diagnostic tests can help rule out other diagnoses and add confidence to the clinical diagnosis of TRALI. Finally, our first case also highlights the potential danger of directed maternal blood donations, which may increase the risk of paediatric TRALI.

Abstract
Transfusion-related acute lung injury (TRALI) is a serious and potentially fatal complication of transfusion of blood and blood components. TRALI is under-diagnosed and under-reported because of a lack of awareness. A number of models have been proposed to explain the pathogenesis of TRALI: an antibody mediated model; a two-event biologically active mediator model; and a combined model. TRALI can occur with any type of blood product and can occur with as little as one unit. Its presentation is similar to other forms of acute lung injury and management is predominantly supportive. The main strategy in combating TRALI is prevention both through manipulation of the donor pool and through clinical strategies directed at reducing transfusion of blood products including, but not limited to, evidence-based lower transfusion thresholds. This article presents a review of TRALI and addresses the definition, pathology, pathogenesis, clinical manifestations, treatment and prevention of the syndrome.

Abstract
We describe transfusion-related acute lung injury (TRALI) in 2 acute leukemia cases to increase awareness of this under reported serious transfusion complication syndrome in multitransfused patients. There are a number of reports in multitransfused patients with nonmalignant disorders. However, reports of pediatric oncology patients are few, suggesting a lack of recognition or misdiagnosis of the syndrome. A disproportionately high number of fatalities in children is recorded in the literature. This highlights the need for increased awareness and appropriate treatment of this serious complication of transfusion. Although TRALI is initially a clinical diagnosis, the laboratory investigation is vital as it contributes to defining the pathogenesis of the syndrome and importantly facilitates the effective management of implicated donations and donors. An investigational strategy for suspected cases is presented and the results are discussed in the context of current proposed mechanisms for TRALI. As each transfused blood product is associated with a potential risk of TRALI, more frequent reports in patients receiving large volume or recurrent transfusion would be expected.

Abstract
Transfusion-related acute lung injury (TRALI) is a life-threatening adverse event of transfusion, which has an increasing incidence in the United States and is the leading cause of transfusion-related death. TRALI and acute lung injury (ALI) share a common clinical definition except that TRALI is temporally- and mechanistically-related to transfusion of blood or blood components. A number of different models have been proposed to explain the pathogenesis. The first is an antibody-mediated event whereby transfusion of anti-HLA, class I or class II, or anti-granulocyte antibodies into patients whose leukocytes express the cognate antigens. The antibody:antigen interaction causes complement-mediated pulmonary sequestration and activation of neutrophils (PMNs) resulting in TRALI. The second is a two-event model: the first event is the clinical condition of the patient resulting in pulmonary endothelial activation and PMN sequestration, and the second event is the transfusion of a biologic response modifier (including anti-granulocyte antibodies, lipids, and CD40 ligand) that activates these adherent PMNs resulting in endothelial damage, capillary leak, and TRALI. These hypotheses are discussed with respect to animal models and human studies that provide the experimental and clinical relevance. The definition of TRALI, patient predisposition, treatment, prevention and reporting guidelines are also examined.

Abstract
Although the blood supply has become safer with regard to transmission of infectious agents, attention should continue to focus on understanding and eliminating the other serious risks associated with transfusion. Transfusion-related acute lung injury (TRALI) is one such risk, only recently becoming recognized as an important and potentially preventable clinical syndrome. Strategies for prevention of TRALI, however, must rely on knowledge regarding its etiology and diagnosis, and significant gaps in our understanding of the syndrome currently exist. This review summarizes what is known and unknown about the incidence, severity, etiology, diagnosis, and prevention of TRALI and the potential consequences of these knowledge gaps.

Abstract
Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-associated mortality. TRALI occurs in children and adults, but the syndrome has not been reviewed from a pediatric perspective. We reviewed the literature on TRALI from a pediatric perspective. TRALI has been documented in pediatric patients, especially in the setting of hematologic malignancy. Additional TRALI cases have been reported in pediatric patients with a variety of diagnoses. TRALI is likely to be much more common than previously appreciated in the pediatric patient population. TRALI should be considered in the differential diagnosis of all pediatric patients who develop new acute lung injury (ALI) or acute respiratory distress syndrome (ARDS) during or within six hours of a blood product transfusion. When a case of TRALI is suspected, a transfusion reaction report to the blood bank is important to initiate the investigation and identify the implicated donor.

Abstract
A 50-year-old male presented for a Whipple's procedure to excise a pancreatic lesion. Massive transfusion of packed cells and fresh frozen plasma was required. Towards the end of the procedure, the patient developed sudden onset of frank pulmonary oedema and hypotension. A presumptive diagnosis of transfusion related lung injury was made after prompt investigations excluded circulatory overload or cardiogenic shock as the cause. This case report describes an increasingly common and life-threatening sequela of blood product transfusion, the management of which is complicated by the current lack of specific diagnostic tests.
