Transfusion-related acute lung injury (TRALI) can cause morbidity and mortality. We present the case of teenager who developed dyspnea and hypoxemia few hours after red cell transfusion. After being admitted for close monitoring and oxygen therapy, her symptoms spontaneously resolved. Message: dyspnea during red cell transfusion should raise the suspicion of TRALI.

SLC44A2 was discovered as the target of an antibody that causes hearing loss. Knockout mice develop age related hearing loss, loss of sensory cells and spiral ganglion neurons. SLC44A2 has polymorphic sites implicated in human disease. Transfusion related acute lung injury (TRALI) is linked to rs2288904 and genome wide association studies link rs2288904 and rs9797861 to venous thromboembolism (VTE), coronary artery disease and stroke. Here we report linkage disequilibrium of rs2288904 with rs3087969 and the association of these SLC44A2 SNPs with Meniere's disease severity...

Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related fatalities and is characterized by the onset of acute respiratory distress within six hours following blood transfusion. In most cases, donor antibodies are suggested to be involved, however, the pathogenesis is poorly understood. A two-hit model is generally assumed to underlie TRALI pathogenesis where the first hit consists of a patient predisposing factor such as inflammation and the second hit is due to donor antibodies present in the transfused blood...

BACKGROUND: To reduce the risk of transfusion-associated acute lung injury (TRALI), a high number of plasma donors were tested for human leukocyte antigen (HLA) and human neutrophil antigen (HNA) antibodies. For HNA antibody detection, the gold standard is a combination of the granulocyte immunofluorescence test (GIFT) and the granulocyte agglutination test (GAT). However, these tests are not suitable for a high-throughput of samples. STUDY DESIGN AND METHODS: To evaluate the new generation of the LABScreen MULTI assay (One Lambda, Inc...

BACKGROUND: Transfusion-related acute lung injury (TRALI) is a significant cause of mortality, especially after transfusions containing antibodies to major histocompatibility complex (MHC) class II antigens. We hypothesize that a first event induces both 1) polymorphonuclear neutrophils (PMNs) to express MHC class II antigens, and 2) activation of the pulmonary endothelium, leading to PMN sequestration, so that the infusion of specific MHC class II antibodies to these antigens causes PMN-mediated acute lung injury (ALI)...

BACKGROUND: Rectus sheath hematoma (RSH) represents a rare, but serious cause of abdominal pain. CASE: Here we discuss the case of a healthy multigravida female who presented at 28 weeks gestation with spontaneous RSH. Conservative management with multiple blood transfusions led to the development of transfusion related acute lung injury (TRALI) and intensive care unit admission. She was managed with noninvasive ventilatory support, gradually improved, and was weaned of ventilation...

Lysophosphatidylcholines (lysoPCs) are effective polymorphonuclear neutrophil (PMN) priming agents implicated in transfusion-related acute lung injury (TRALI). LysoPCs cause ligation of the G2A receptor, cytosolic Ca(2+) flux, and activation of Hck. We hypothesize that lysoPCs induce Hck-dependent activation of protein kinase C (PKC), resulting in phosphorylation and membrane translocation of 47 kDa phagocyte oxidase protein (p47(phox)). PMNs, human or murine, were primed with lysoPCs and were smeared onto slides and examined by digital microscopy or separated into subcellular fractions or whole-cell lysates...

Most adverse blood transfusion (BT) events are immune-mediated and in the majority of severe reactions antibodies can be identified as causal factors. Alloimmunization not only causes symptomatic reactions, transfused cells can also be (silently) destroyed. Immunization by BT can contribute to hemolytic disease of the newborn as well as to allograft rejection after transplantation. Reversely, pregnancy and transplantation may evoke immunity hampering transfusion therapy. Besides causing mortality and morbidity, alloimmunization has a huge economic impact...

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...

BACKGROUND: Transfusion-related acute lung injury (TRALI) is a major cause of death associated with transfusion. Nevertheless it is still misdiagnosed and underreported. We present a case of this serious complication in order to make it more familiar to clinicians and indicate proper medical management, which is significant not only for the patients presenting TRALI symptoms but also for future recipients of blood components. CASE PRESENTATION: A 32-year-old white woman with in-vitro fertilization in anamnesis was admitted to Department of Obstetrics and Gynecology because of abdominal pain...

Transfusion-related acute lung injury (TRALI) is a rare complication of transfusion, for which the true incidence remains obscure, since there are a number of factors that may lead to misdiagnosis. Despite this, it continues to be the leading cause of transfusion-associated mortality. Here we present a historical case of TRALI in an elderly female who received group AB plasma and discuss how current mitigation strategies would likely have prevented its occurrence. It is important to remember that both immune and non-immune factors play a role in TRALI pathogenesis, and although current preventative strategies may decrease TRALI's incidence, they likely will not eliminate it...

Recently two articles have been published in TRANSFUSION in which the authors propose to change the current definition on transfusion-related acute lung injury (TRALI). It was proposed to view TRALI from the perspective of detectability versus nondetectability of leukoreactive alloantibodies (Transfusion 2015;55:1128-34). The authors argue that only cases in which leukoreactive alloantibodies can be detected should be defined as "true" TRALI in analogy with the understanding of the pathophysiology of heparin-induced thrombocytopenia...

Therapeutic plasma exchange (TPE) is an extracorporeal treatment with reported beneficial as well as detrimental effects on circulation. However, there is a lack of data using advanced hemodynamic monitoring during TPE. Therefore, we investigated the effects of TPE on hemodynamic parameters derived from transpulmonary thermodilution (TPTD) as well as the risk for transfusion-related acute lung injury (TRALI). We compared hemodynamic parameters obtained before and after a total of 30 sessions of TPE treatment in 10 intensive care unit patients...

UNLABELLED: Essentials Role of platelets in immunological transfusion-related acute lung injury (TRALI) is debated. Immunological TRALI was tested in mice exhibiting severe thrombocytopenia or platelet dysfunction. Platelets are required to prevent lung hemorrhage but not edema formation and respiratory distress. Platelets are dispensable for the initiation and development of TRALI. SUMMARY: Background Transfusion-related acute lung injury (TRALI) is a serious transfusion-related complication...

BACKGROUND AND OBJECTIVES: Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related mortality. To support the diagnosis of antibody-mediated TRALI, HLA and HNA antibodies are tested in involved blood donors. Identification of antibody positive donors is important as exclusion of these donors is part of preventative strategies against TRALI. We compared cellular-based versus bead-based techniques for diagnosis of antibody-mediated TRALI. MATERIALS AND METHODS: All reported TRALI cases in the Netherlands during a 5-year period were evaluated...

Transfusion-related acute lung injury (TRALI) is a serious adverse reaction of transfusion, and presents as hypoxemia and non-cardiogenic pulmonary edema within 6 hours of transfusion. A 14-year-old primigravida woman at 34 weeks of gestation presented with upper abdominal pain without dyspnea. Because she showed the syndrome of HELLP (hemolysis, elevated liver enzymes, and low platelet count), an emergency cesarean section delivery was performed, and blood was transfused. In the case of such patients, clinicians should closely observe the patient's condition at least during the 6 hours while the patient receives blood transfusion, and should suspect TRALI if the patient complains of respiratory symptoms such as dyspnea...

BACKGROUND: Several studies had demonstrated that leucocyte antibodies including anti-human leucocyte antigen (anti-HLA) antibodies (class I and class II) and anti-human neutrophil antigen (anti-HNA) antibodies (HNA-1, -2 and -3) present in the blood products are responsible for transfusion-related acute lung injury (TRALI). Therefore, selection of blood products exclusive of anti-HLA and anti-HNA antibodies may lower the risk of TRALI reaction. However, the prevalence of leucocyte antibodies among blood donors in China is currently not known...

Transfusion-related acute lung injury (TRALI) may be induced by plasma, platelet concentrates and red blood cell concentrates. The mechanism leading to TRALI is thought to involve two steps. The priming step consists of previous inflammatory pathological conditions or external factors attracting leukocytes to lung vessels and creating conditions favorable for the second step, in which anti-HLA or anti-HNA antibodies or biologically active lipids, usually in transfused blood products, stress leukocytes and inflame lung epithelia...

BACKGROUND: The use of male-donor-predominant plasma has reduced the risk of transfusion-related acute lung injury (TRALI), but the possible benefit of different mitigation strategies for other components is unknown. We evaluated the risk of TRALI from apheresis platelets (PLTs) to predict the effect of selectively testing female plateletpheresis donors who have been pregnant for HLA antibodies. STUDY DESIGN AND METHODS: The American Red Cross hemovigilance program classified TRALI cases from apheresis PLTs or red blood cells (RBCs) in 2006 to 2013 or from predominantly male-donor (>95%) plasma in 2008 to 2013 and compared the component-specific TRALI rates...
