ABSTRACT

Introducción: La lesión pulmonar aguda (TRALI) y la sobrecarga circulatoria (TACO) son las principales causas de morbilidad y mortalidad relacionadas con la transfusión. La TRALI se presenta durante o después de las transfusiones de plasma y sus derivados, o por inmunoglobulinas en alta concentración intravenosa; se asocia a procesos sépticos, cirugías y transfusiones masivas. La TACO es la exacerbación de manifestaciones respiratorias en las primeras 6 horas postransfusión. Reporte caso: Paciente de sexo masculino de 38 días de vida, ingresó al servicio de urgencias con un cuadro clínico de 8 días de evolución, caracterizado por dificultad respiratoria dado por retracciones subcostales y aleteo nasal sin otro síntoma asociado, con antecedentes de importancia de prematuridad y bajo peso al nacer. El reporte de hemograma arrojó cifras compatibles con anemia severa, por lo que requirió transfusión de glóbulos rojos empaquetados desleucocitados. El paciente presentó un cuadro respiratorio alterado en un periodo menor a 6 horas, por lo que se descartaron causas infecciosas y finalmente se consideró cuadro compatible con TRALI. Conclusiones: Se debe considerar una lesión pulmonar aguda relacionada con una transfusión de sangre si se produce una insuficiencia respiratoria aguda durante o inmediatamente después de la infusión de hemoderivados que contienen plasma.


Introduction: Acute lung injury (TRALI) and circulatory overload (TACO) are the main causes of transfusion-related morbidity and mortality. TRALI occurs during or after transfusions of plasma or its derivatives, or by immunoglobulins in high intravenous concentration; it is associated with septic processes, surgeries, and massive transfusions. TACO is the exacerbation of respiratory manifestations in the first 6 hours post transfusion. Case report: A 38-day-old male was admitted to the emergency department with clinical symptoms experienced over the course of 8 days and characterized by respiratory distress due to subcostal retractions and nasal flaring with no other associated symptoms. Important antecedents included prematurity and low birth weight. The hemogram report showed figures compatible with anemia, which benefited from transfusion of packed red blood cells without leukocytes. In a period of less than 6 hours, the patient presented altered respiratory symptoms, practitioners ruled out infectious causes and finally considered clinical signs compatible with TRALI. Conclusion: Acute lung injury related to blood transfusion should be considered if acute respiratory failure occurs during or immediately after infusion of plasma-containing blood products.

ABSTRACT

【Objective】 To investigate the effects and mechanisms of different doses of fingolimod (FTY720) on non-antibody-mediated transfusion-related acute lung injury (TRALI). 【Methods】 A TRALI mouse model was constructed using lipopolysaccharide (LPS) pre-stimulation and platelets (Plt) of different storage days for second strike. The success of the modeling was determined by protein concentration in lung tissue homogenates, myeloperoxidase (MPo) activity, lung wet/dry weight ratio (W/D ratio), lung tissue damage score and pathological sections. Ceramide and sphingosine-1-phosphate (S1P) contents in platelets of different storage days were detected. FTY720 was administered 1 h after LPS injection to investigate the role of FTY720 in TRALI. The expression levels of vascular endothelial cadherin (VE-cadherin) and zonula occludens-1 (ZO-1) were analyzed by WB. 【Results】 Mice infused with stored 5-day Plt (d5Plt group) exhibited typical signs of TRALI, and the differences in lung tissue homogenate protein concentration (6 546.38±409.50) μg/mL, MPO activity (49.38±4.43) U/L, W/D ratio 4.79±0.21, and lung tissue damage score 7.24±0.38 from the rest of the groups were statistically significant (P<0.05). With the increase of platelet storage time, the ceramide content gradually increased and S1P content gradually decreased, and the ratio of the two was imbalanced. d5Plt showed statistically significant differences (P<0.01) in ceramide content (58.37±5.69) μmol/L and S1P content (149.81±4.86) nmol/L from the rest of the groups. After preventive administration of FTY720, 1 mg/kg FTY720 had no significant effect on TRALI mice, whose lung tissue homogenate protein concentration (6 170.26±545.50) μg/mL, MPO activity (45.97±4.79) U/L, W/D ratio 4.88±0.25, and lung tissue damage score 7.92±0.65 were significantly higher than those of the normal and LPS control groups (P<0.01). The low-dose (0.5, 0.2, and 0.1 mg/kg) FTY720 group alleviated lung injury, and its protein concentration, MPO activity, W/D ratio, and lung tissue injury score were significantly lower than those of the d5Plt group (P<0.05). Pathological sections also showed similar results. In terms of endothelial intercellular junction protein expression, the VE-cadherin expression levels in the 1 mg/kg FTY720 group were significantly lower than those in the normal and LPS control groups (P<0.05), and the VE-cadherin and ZO-1 expression levels in the low-dose (0.5, 0.2, and 0.1 mg/kg) FTY720 group were significantly higher than those in the d5Plt group (P<0.05), which tended to be normalized. 【Conclusion】 In this study, a TRALI mouse model was successfully established by one strike of LPS and two strikes of d5Plt. Low doses of FTY720 (0.5, 0.2, 0.1 mg/kg) were protective against TRALI, while high doses of FTY720 (1 mg/kg) may aggravate the symptoms of TRALI. This protective effect may be somewhat dependent on the expression of VE-cadherin and ZO-1.

ABSTRACT

【Objective】 To explore the risk factors of transfusion-related acute lung injury (TRALI). 【Methods】 The clinical symptoms, signs, imaging examinations, and laboratory test results of two patients with TRALI after blood transfusion were retrospectively analyzed, and human leukocyte antigen (HLA) genotyping of the patient and HLA antibodies typing of the plasma donors were performed. 【Results】 The clinical manifestations and laboratory parameters of two patients were consistent with those of TRALI after blood transfusion. After timely clinical respiratory support treatment, all patients were improved. Blood donors produced high titers of HLA-Ⅱ antibodies after pregnancy, including antibodies that specifically recognize the patient′s HLA antigen. 【Conclusion】 Two patients developed TRALI after platelet transfusion from a female blood donor, which was caused by HLA-Ⅱ antibodies.

ABSTRACT

Acute lung injury/acute respiratory distress syndrome (ALI/ARDS) is a common complication after liver transplantation, which could prolong the length of postoperative intensive care unit stay, affect clinical efficacy of liver transplantation and even lead to the death of recipients. ALI/ARDS has attracted extensive attention from liver transplant surgeons in clinical practice. ALI/ARDS after liver transplantation may be directly caused by pulmonary factors (such as mechanical ventilation-related lung injury, lung infection and aspiration, etc.) or indirectly induced by non-pulmonary factors (such as severe infection outside the lungs, blood transfusion and ischemia-reperfusion injury, etc.). In this article, the diagnostic criteria, incidence, mechanism, risk factors, laboratory and clinical diagnostic approaches and treatment of ALI/ARDS after liver transplantation were reviewed, aiming to deepen the understanding and cognition of ALI/ARDS during the perioperative period of liver transplantation and provide reference for the diagnosis and treatment of ALI/ARDS following liver transplantation.

ABSTRACT

Resumen Las complicaciones pulmonares asociadas a la transfusión de hemoderivados son reacciones adversas graves y potencialmente mor tales. La Lesión Pulmonar Aguda Relacionada a Transfusión (TRALI), es una de las más frecuentes y con mayor mortalidad asociada. Es una entidad infradiagnosticada debido a su sintomatología inespecífica, a la ausencia de biomarcadores séricos específicos para su diagnóstico y a que aún la evidencia acerca de sus causas es heterogénea. El objetivo del presente artículo es documentar un caso clínico de TRALI y posteriormente, basados en la literatura actual, consolidar los aspectos fundamentales para la identificación oportuna de esta entidad y de dos diagnósticos diferenciales en el contexto de transfusión de hemoderivados y trauma: la Sobrecarga Circulatoria Asociada a Transfusión (TACO) y el Embolismo graso (EG). Así pues, se expone el caso clínico de una paciente adulto joven quien en el contexto de un politraumatismo requiere transfusión de hemoderivados, desarrollo de cuadro clínico compatible con TRALI; de esta manera, la discusión incluye aspectos epidemiológicos, fisiopatología, hallazgos imagenológicos y diagnóstico. Se logra concluir que es preciso poner a disposición de los profesionales del área de la salud literatura científica que favorezca la identificación de estas patologías con base en criterios clínicos, paraclínicos e imagenológicos, para así mismo, disminuir el riesgo de presentación y la mortalidad asociada.


Abstract Pulmonary complications associated with the transfusion of blood products are severe, potentially mortal adverse reactions. The transfusion-related acute lung injury (TRALI) is one of the most common and with higher associated mortality. It is an underdiagnosed entity due to its unspecified symptoms, the absence of diagnosis-specific serum biomarkers and the fact that the evidence about its causes is still heterogeneous. The objective of this article is to document a clinical case of TRALI and then, basing on the current literature, consolidate key aspects for the timely identification of this disease and of two differential diagnoses within the context of transfusion of blood products and trauma: the transfusion-associated circulatory overload (TACO) and fat embolism (FE). So, we pres ent the clinical case of a female young adult patient requiring a transfusion of blood products due to a polytraumatism whose clinical condition is compatible with TRALI; thus, the discussion includes epidemiological aspects, physiopathology, imaging findings and diagnosis. We conclude that it is necessary to provide healthcare professionals with scientific literature that favors the identification of these diseases basing on clinical, paraclinical and imaging criteria so as to reduce the risk of presentation and associated mortality.

ABSTRACT

【Objective】 To explore the feasibility of tirofiban, a platelet surface glycoprotein (GP)Ⅱb/Ⅲa receptor antagonist intervene in transfusion-related acute lung injury (TRALI), by inhibiting platelet activation and by preventing platelet and neutrophil binding to form aggregates. 【Methods】 1) Fifty wild-type male Balb/c mice, aged 8 to 10 weeks, were randomly divided into TRALI, normal, tirofiban TRALI intervention, isotype control and tirofiban normal intervention groups. In the TRALI model, tirofiban TRALI intervention and isotype control groups, each mouse was injected intraperitoneally with lipopolysaccharide (LPS) 0.1 mg/kg, and after 18 h with 4.5 mg/kg anti-MHC-I or IgG2a isotype control antibody, in which 0.5 μg/g tirofiban was injected 30 min before anti-MHC-I injection, and was labeled as tirofiban TRALI intervention. The group without any treatment was set as normal group. The tirofiban normal intervention group was injected with only 0.5 μg/g tirofiban into the tail vein, 30 min before the injection of anti-MHC-I. 2) After antibody injection, the mice were observed for 2 h, then executed with their lungs removed, and the extent of lung injury and the intervention effect of tirofiban were analyzed by comparing the differences in lung dry to wet ratio, total protein, myeloperoxidase (MPO), inflammatory factors and quantitative results of HE staining. The platelet activation level in whole blood and immunofluorescence (IF) quantification of platelet and neutrophil fluorescence were detected by flow cytometry to analyze the mechanism of tirofiban on TRALI. 【Results】 1) The indexes of lung injury in the tirofiban TRALI intervention group and TRALI model group for HE staining were 0.663 3±0.141 9 vs. 0.173 3±0.120 4 (P<0.05), respectively; 2) Platelet activation levels(%)in whole blood in the TRALI group, normal group and tirofiban TRALI intervention group were 22.87±9.943 vs 5.070±2.234 vs 5.767±3.224(P<0.05), respectively. 3) The mean fluorescence density of platelet neutrophil aggregates for IF detection in the tirofiban intervention group and TRALI model group was 21.89±3.536 vs. 32.77±0.9624 (P<0.05). 【Conclusion】 The platelet GP Ⅱ b/Ⅲa-specific inhibitor tirofiban inhibited platelet-neutrophil binding in mice, thus could possibly intervene in TRALI.

ABSTRACT

【Objective】 To investigate the viability of rapamycin-treated rapamycin-treated dendritic cells (DCs) in intervening transfusion-related acute lung injury (TRALI) after infection. 【Methods】 1)The TRALI mouse model was induced by lipopolysaccharide (LPS) combined with anti-H2Kd antibody. The mice anal temperature and the wet/dry ratio of lung, kidney, spleen and brain tissues were measured. 2) Mouse bone marrow-derived DC cells were induced in vitro and treated with rapamycin (10nM) for 24h. 3) Mice were injected with or without rapamycin or rapamycin-treated DC, then injected with LPS intraperitoneally one hour later, finally injected with anti-H2Kd antibody 24 hours later to induce the onset of TRALI. The death situation of the mice was observed and recorded. The condition of mice after the onset of TRALI was analyzed by mouse body temperature, lung wet-dry ratio, and pleural effusion weight and lung histopathological sections. 【Results】 By comparing the induction effects of anti-H2Kd antibody solutions with different concentrations and volumes, the mouse model induced by 0.1mg/kg LPS combined with 4.5 mg/kg anti-H2Kd antibody (infusion volume of 100μL) was selected as the TRALI mouse model for this study. After the onset of TRALI, the wet/dry ratio of the lungs could be significantly increased and the body temperature could be significantly reduced in the model mice. After the intervention of TRALI mice with DCs treated with rapamycin, the mortality rate was significantly reduced, and the lung tissue lesions of the mice were significantly improved, whose protection effect was better than that of the rapamycin-treated group. Compared with the TRALI incidence group, the weight of pleural effusion in the intervention group was significantly reduced (P<0.05), but there was no significant difference in lung wet/dry ratio and body temperature. 【Conclusion】 The combination of LPS and antibodies can effectively induce a stable and typical TRALI mouse model, suggesting that the presence of infectious inflammation and blood transfusion-related inflammatory substances are the decisive factor for the pathogenesis of TRALI. Meanwhile, DCs treated with rapamycin have a protective effect on post-infection transfusion-related acute lung injury, which is expected to be a potential cell therapy strategy to intervene in the exacerbation of TRALI.

ABSTRACT

RESUMEN La lesión pulmonar aguda producida por transfusión (TRALI, por sus siglas en inglés) es un síndrome clínico relativamente raro, que puede constituir una amenaza para la vida y que se caracteriza por insuficiencia respiratoria aguda, edema pulmonar no cardiogénico e hipotensión arterial durante o en el transcurso de 6 horas después de una transfusión de productos hemáticos. Aunque su verdadera incidencia es desconocida, se le ha atribuido 1 caso por cada 5000 transfusiones de cualquier producto hemático y ha sido una de las causas más frecuentes de muerte relacionada con la transfusión. Se presenta un caso de TRALI en el perioperatorio de una cirugía cardíaca con manifestaciones clínicas extremas, cuyo abordaje terapéutico fue extremadamente difícil para el equipo médico-quirúrgico, debido al contexto clínico en el que se presentó: cirugía cardíaca con circulación extracorpórea por diagnóstico de endocarditis infecciosa, lesión pulmonar previa y antecedente de otro tipo de reacción postransfusional.


ABSTRACT Transfusion-Related Acute Lung Injury (TRALI) is a relatively unusual, life-threatening clinical syndrome, characterized by acute respiratory failure, hypotension, and non-cardiogenic pulmonary edema during or within 6 hours after a blood product transfusion. Although its true incidence is unknown, it has been attributed one case per 5.000 transfusions of any blood product and has been one of the most frequent causes of transfusion-related death. We present a case of TRALI in the perioperative period of cardiac surgery with extreme clinical manifestations, whose therapeutic approach was extremely difficult for the medical-surgical team, due to its complex clinical setting: cardiac surgery with cardiopulmonary bypass due to diagnosis of infective endocarditis, previous lung injury and history of other post-transfusion reaction.

ABSTRACT

Transfusion-related acute lung injury (TRALI), with clinical manifestation, diagnosis and pathological mechanism consistent with acute lung injury(ALI), belongs to a sub-category of ALI. Excessive deposition of fibrin in lung is one of the characteristic of ALI, and reversing fibrin formation is of great significance to intervene ALI. The decrease of fibrinolytic activity is one of the important causes of excessive deposition of fibrin in lung, and also the important pathological feature of TRALI. This article discusses the potential of modulating fibrinolytic activity to intervene TRALI from the perspective of regulating the effectiveness of fibrinolytic activity to intervene ALI.

ABSTRACT

Recent studies have shown that a series of structural and functional changes would occur during the process of platelet collection, storage and transfusion. The storage of platelets would induce the production of extracellular vesicles. During the process of platelet transfusion, extracellular vesicles play a critical role by carrying diverse substances under various pathophysiological conditions, which causes adverse reactions to blood transfusion. Ceramide and soluble CD40L (sCD40L) carried by platelet-derived extracellular vesicles may lead to transfusion-related acute lung injury (TRALI). Extracellular vesicles containing mtDNA are considered as damage-associated molecular patterns (DAMPs), which can mediate local and systemic inflammation and promote inflammation through interactions with leukocytes and monocytes. Platelet derived extracellular vesicles contain lots of procoagulant substances, which are considered as prethrombotic substances. The RNA of varying species or content carried by vesicles during the process of platelet storage may also related to the occurrence of adverse reactions to blood transfusion.

ABSTRACT

【Objective】 To explore the role of NF-κB signaling pathway in the process of platelet storage on neutrophil-mediated human pulmonary microvascular endothelial cell injury, in order to further clarify the mechanism of platelet-mediated transfusion-related acute lung injury. 【Methods】 A co-culture system of human lung microvascular endothelial cells and neutrophils was established. A simple co-culture group and NF-κB inhibitor addition group were set up simultaneously, and then the platelet supernatant stored for 3 and 5 days were added. The expression levels of NF-κB pathway protein IκBα and cytokines (IL-6, IL-8, IL-1β and TNF-α) were detected, the cell death ratio (the number of dead cells/total number of cells) and the expression level of apoptotic protein Caspase 3 were calculated by Trypan blue staining. 【Results】 In the simple co-culture group with 5-day stored platelet supernatant added, the expression level of NF-κB pathway protein IκBα decreased significantly as the incubation time prolonged (simple co-culture 39 281.48±289.36 vs control 11 267.68±407.27, P0.05)when 5-day stored platelet supernatant was compared with 3-day stored one. The cell death rate(0.27±0.12 vs 3.33±0.31)and the expression level of apoptotic protein Caspase 3(17 821.11±611.55 vs 42 064.42±542.86)showed a significant increase(P0.05)as compared with the controls. Significant difference in the cell death rate of co-culture group with 5-day stored platelet supernatant added was observed as in comparison with the control (0.27±0.12 vs 1.26±0.11, P0.05). No significant difference was noticed in the expression level of apoptotic protein Caspase3(10 502.77±457.55 vs 10 424.16±471.53, P>0.05)when 5-day stored platelet supernatant was compared with 3-day stored one. 【Conclusion】 The NF-κB signaling pathway may be involved in storing platelets to regulate inflammation and apoptosis, thus affecting the process of neutrophil-mediated human pulmonary microvascular endothelial cell injury.

ABSTRACT

ABSTRACT Case report of a patient with an immunodeficiency who demands regular replacement of intravenous immunoglobulin. She presented an episode of transfusion-related acute lung injury shortly after using an immunoglobulin product different than the one she usually received. The patient evolved with respiratory changes (hypoxia, dyspnea, change in pulmonary auscultation) minutes after the end of the infusion, and received non-invasive respiratory support. She was discharged after 36 hours with good outcome. The patient achieved full recovery, showing no further reactions in subsequent immunoglobulin infusions (no longer receiving the product that was used when she had the episode of transfusion-related acute lung injury). Although rare, this reaction is potentially serious and has no specific treatment other than supportive therapy. The literature is scarce regarding the risk of recurrence. The decision on whether to proceed with immunoglobulin therapy after this adverse effect should be analyzed individually, assessing the possible risks and benefits for the patient.


RESUMO Relato de caso de paciente com imunodeficiência que necessitava de reposição regular de imunoglobulina endovenosa. Ela apresentou um episódio de lesão pulmonar aguda relacionada à transfusão após uso de produto de imunoglobulina diferente daquele que recebia habitualmente. Evoluiu com alterações respiratórias (hipóxia, dispneia e alteração de ausculta pulmonar) minutos após o fim da infusão, necessitando de suporte respiratório não invasivo. A paciente recebeu alta hospitalar após 36 horas, com boa evolução. Obteve recuperação total dos sintomas, sem mais reações nas infusões subsequentes de imunoglobulina (sendo optado por não mais prescrever o produto que foi usado quando ocorreu o episódio de lesão pulmonar aguda relacionada à transfusão). Apesar de rara, essa reação é potencialmente grave, não possui tratamento específico além de terapia de suporte, e há pouca informação na literatura sobre o risco de recorrência. A decisão sobre o seguimento da terapia com imunoglobulina após esse efeito adverso deve ser analisada individualmente, avaliando os possíveis riscos e benefícios para o paciente.

ABSTRACT

Transfusion-related acute lung injury (TRALI) is defined as a new episode of acute lung injury that occurs during or within 6 hours of a completed transfusion, which is one of the leading causes of transfusion-related morbidity and mortality. We present a case of TRALI in a 29-year-old parturient with myelodysplastic syndrome scheduled for cesarean section. The parturient developed hypoxemia and dyspnea after preoperative transfusion of platelets following apheresis to eliminate a unit of leucocyte in order to correct thrombocytopenia. She underwent emergent caesarean section for fetal distress. After surgery, the chest radiograph showed diffuse haziness of both lung fields. Direct and indirect antiglobulin tests were negative, and hemolytic transfusion reaction was ruled out. Pro-BNP 347.3 pg/ml also excluded transfusion-associated circulatory overload. The parturient completely recovered after oxygen support for 2 days. It is important to recognize TRALI as soon as possible to minimize perioperative morbidity and mortality.

ABSTRACT

Resumen: Los recién nacidos, sobre todo los pretérminos, constituyen uno de los grupos que reciben más hemoderivados. Si bien se han disminuido los riesgos asociados a las transfusiones, aun así pueden presentarse complicaciones1,2. TRALI (Tranfusion Related Acute Lung Injury; en español: lesión pulmonar aguda asociada a transfusión) es una complicación poco frecuente pero potencialmente grave. Reconocida inicialmente en adultos, posteriormente se describieron casos en niños. En neonatos solamente existe un caso confirmado y publicado a nivel internacional. La incidencia real es incierta, dado el poco conocimiento de la patología y el subreporte. TRALI resultaría de un daño del endotelio vascular pulmonar, causando edema pulmonar y subsecuentemente hipoxemia. El tratamiento es de sostén3. La prevención se basa principalmente en la revisión permanente de las indicaciones de transfusión de hemoderivados y en la comunicación fluida con el equipo de hemoterapia para su diagnóstico oportuno. Se describe el caso clínico de un recién nacido prematuro que durante una transfusión de concentrado de glóbulos rojos presentó hipoxemia con necesidad de asistencia ventilatoria mecánica, alteraciones hemodinámicas y fiebre. Se descartaron procesos infecciosos. La radiografía de tórax mostró infiltrados compatibles con edema pulmonar. Se descartó la falla cardíaca. El tratamiento realizado fue de sostén de las funciones vitales. La evolución fue favorable en el correr de 72 horas. Se comunicó el caso al servicio de hemoterapia. A fin de prevenir transfusiones innecesarias es importante que cada servicio revise periódicamente sus guías de transfusión de hemoderivados.


Summary: Newborns, especially preterm newborns, are one of the age groups that receive the most hemoderivatives. Although the progress made in the field of hemotherapy have made it possible to reduce the risks associated with transfusions, in some cases there are still complications1,2. TRALI (transfusion related acute lung injury) is a rare but potentially serious complication. It was initially detected in adults, though cases were later described in children. In newborns, only one case has been confirmed and published globally. The actual incidence is uncertain, given the insufficient knowledge of the pathology and the fact that findings have been under reported. TRALI results from pulmonary vascular endothelial damage and causes pulmonary edema and subsequent hypoxemia. Treatment is observed with supportive treatment3. Prevention is mainly based on the permanent review of the hemoderivatives' transfusion directives and on the fluent communication among members of the hemotherapy medical team in order to ensure a timely diagnosis. The clinical case described below is that of a preterm newborn who, during a transfusion of red blood cell concentrate, showed hypoxemia, hemodynamic alterations and fever and required mechanical ventilatory support. Infectious processes were ruled out. Chest X-Rays showed infiltrates compatible with pulmonary edema. Heart failure was ruled out. The treatment was performed to support vital functions. The evolution was favorable in the course of 72 hours. The case was reported to the Hemotherapy Service. Blood component transfusion guidelines should be regularly reviewed in order to prevent the performance of unnecessary transfusions.


Resumo: Os recém-nascidos, especialmente os prematuros, são um dos grupos que recebem maior quantidade de hemoderivados. Embora os riscos associados tenham diminuído com o tempo, as transfusões ainda podem trazer complicações1,2. A TRALI (lesão pulmonar aguda relacionada à transfusão) é uma complicação rara, mas potencialmente grave. Inicialmente reconhecida em adultos, os casos foram posteriormente descritos em crianças. Em neonatos, há apenas um caso confirmado e publicado a nível internacional. A incidência real é incerta, dado que existe pouco conhecimento da patologia e é pouco relatada. A TRALI é provocada por danos no endotélio vascular pulmonar e causa edema pulmonar e subsequentemente hipoxemia. O tratamento é de suporte3. A prevenção baseia-se principalmente na revisão permanente das indicações de transfusão de hemoderivados e na comunicação fluida com a equipe de hemoterapia para o diagnóstico oportuno. Descrevemos o caso clínico de um recém-nascido prematuro que apresentou hipoxemia durante transfusão de concentrado de hemácias com necessidade de ventilação mecânica, alterações hemodinâmicas e febre. Descartamos processos infecciosos. A radiografia de tórax mostrou infiltrados compatíveis com edema pulmonar. Descartamos insuficiência cardíaca. Realizamos tratamento de suporte de funções vitais. A evolução foi favorável durante 72 horas. O caso foi relatado ao serviço de Hemoterapia. Para evitar transfusões desnecessárias, é importante que cada serviço revise periodicamente as diretrizes de transfusão de hemoderivados.

ABSTRACT

La lesión pulmonar aguda producida por transfusión (TRALI) es un grave síndrome clínico que se presenta con hipoxemia aguda y edema pulmonar no cardiogénico dentro de las 6 h de una transfusión con productos sanguíneos. La incidencia reportada oscila entre 1 caso cada 5000-100.000 transfusiones. Se han propuesto dos teorías sobre su fisiopatología: inmunomediada y no inmune. El diagnóstico es clínico y el tratamiento, de sostén. La tasa de mortalidad puede llegar al 10%, y la morbilidad es alta. Presentamos un paciente que, durante el posoperatorio inmediato de una artrodesis posterior instrumentada por escoliosis, evoluciona con hipoxemia resistente. En la cirugía, requirió múltiples transfusiones con hemoderivados por sangrado activo, por lo que se arriba al diagnóstico de TRALI. Requirió asistencia respiratoria mecánica con altos parámetros por 72 h y sostén hemodinámico por bajo gasto cardíaco. La evolución fue favorable y recibió el alta hospitalaria a los 11 días, sin complicaciones(AU)


Transfusion-related acute lung injury (TRALI) is a serious clinical syndrome that occurs with acute hypoxemia and non-cardiogenic pulmonary edema within 6 hours of a transfusion with blood products. The reported incidence ranges from 1 case per 5,000-100,000 transfusions. Two theories have been proposed about its pathophysiology, an immune-mediated one and a non-immune one. The diagnosis is clinical, and the treatment is supportive. Mortality may reach 10%, with high morbidity. We report a patient who in the immediate postoperative period of posterior instrumented arthrodesis for scoliosis developed refractory hypoxemia. During surgery, he required multiple blood products transfusions due to active bleeding, so we diagnosed TRALI. The patient required mechanical ventilation with high parameters during 72 hours and hemodynamic support for low cardiac output. The outcome was favorable and he was discharged at day 11 without complications. (AU)

ABSTRACT

A 73-year-old man who underwent redo aortic valve replacement due to dysfunction of tissue heart valve developed hypoxemia with bilateral infiltrates on frontal chest radiograph and hypotension shortly after his operation. Due to the presence of progressive hypotension and hypoxemia, we inserted an intra-aortic balloon pump and, furthermore, provided percutaneous cardiopulmonary support. We ruled out cardiogenic pulmonary edema based on information from various examinations, including echocardiography, and subsequently diagnosed possible transfusion-related acute lung injury (possible TRALI). The patient was treated by mechanical ventilation and circulatory support under close supervision, showing a trend of improvement from postoperative day 2 and discontinuing mechanical ventilation on postoperative day 11. The patient made an uneventful recovery and was discharged on postoperative day 50. Cardiac surgery patients are at particular risk for TRALI, so physicians should consider TRALI whenever a patient develops hypoxemia during or shortly after transfusion. Rapid diagnosis and appropriate treatment of TRALI are especially important in cardiac surgery patients.

ABSTRACT

Development of transfusion-related acute lung injury (TRALI), a non-cardiogenic pulmonary edema, after blood transfusion, is a rare but potentially leading cause of mortality from blood transfusion. We report on a case of TRALI in a 51-year male with acute calculous cholecystitis and liver cirrhosis. As preoperative treatment, he was given ten units of fresh frozen plasma (FFP) for 3 days before the operation. During the transfusion of the 10th unit of FFP, he experienced a sudden onset of hemoptysis, tachypnea, tachycardia, and cyanosis. Bilateral pulmonary infiltration not observed on the chest X-ray at the visit was newly developed. There was no evidence of volume overload but severe hypoxemia. Blood transfusion was stopped and he recovered fully after 8 days of oxygen therapy through a nasal cannula. Although HLA and HNA antibodies were not detected in the donor's blood, HLA antibodies (A2, B57, B58) were detected in the patient's blood. We reported this meaningful case of TRALI that occurred after transfusion of only fresh frozen plasma which did not contain human leukocyte antibody in a patient with HLA antibody.

ABSTRACT

BACKGROUND: Alloantibodies against human neutrophil alloantigen (HNA)-3a are associated with severe and fatal transfusion related acute lung injury (TRALI). HNA-3 genotyping and HNA-3a antibody (Ab) identification are essential to diagnosis and prevention of TRALI caused by HNA-3a Ab. However there had been no laboratory for HNA-3a Ab identification in Korea. The aims of this study were to establish the HNA-3a Ab test in Korea and to estimate the incidence of HNA-3a alloimmunization among pregnant Korean women. METHODS: HNA-3a homozygotes and HNA-3b homozygotes were identified by HNA-3 genotyping. Three HNA-3a homozygotes and three HNA-3b homozygotes are included in the granulocytes panel, which consisted of 10 donors for granulocytes. Sera from 650 pregnant Korean women were tested for granulocyte Ab using a mixed passive hemagglutination assay (MPHA). When a HNA-3a Ab was detected, the woman's HNA-3 was typed to support her HNA-3a alloimmunization. RESULTS: MPHA showed positive reactions in the sera from 26 women (4.0%, 26/650). HLA Abs were detected in 18 women (2.8%, 18/650), among whom HNA Abs were identified simultaneously in 7 women. Granulocyte Abs were detected in sera from 15 women (2.3%, 15/650). The incidence of HNA-3a, HNA-1b, HNA-1a, HNA-2a, and unidentified HNA Abs among pregnant Korean women was 0.77% (5/650), 0.77% (5/650), 0.62% (4/650), 0.15 (1/650), and 0.31% (2/650), respectively. CONCLUSION: In this study, we established the HNA-3a Ab test using MPHA for diagnosis and prevention of TRALI caused by HNA-3a Ab. The incidence of HNA-3a Ab in pregnant Korean women was 0.77% (5/650).

ABSTRACT

Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related mortalities. Each type of blood product is likely to cause TRALI. Patients with TRALI present with dyspnea/respiratory distress and fever. The symptoms, signs and chest radiological findings in TRALI are similar to transfusion associated circulatory overload. Therefore, it is difficult to distinguish such from circulatory overloads. We report a case of TRALI in a 49-year-old woman after stored packed red blood cell transfusion. The patient developed hypoxemia and pulmonary edema after packed red blood cell transfusion during postoperative period. The patient completely recovered after an oxygen support for 3 days.
