Resumo: Introducción: el síndrome de dificultad respiratorio agudo (SDRA) es la manifestación más grave de compromiso pulmonar agudo. Actualmente no hay datos disponibles para documentar los factores asociados con la mortalidad en nuestro medio. Diseño del estudio: estudio de cohorte retrospectiva. Objetivo: describir los factores asociados a la mortalidad en pacientes adultos hospitalizados en la unidad de cuidado crítico con SDRA entre enero 2007 y diciembre de 2011. Métodos: se recolectaron datos con respecto a causas de SDRA, estancia hospitalaria y en la UCI, gravedad de la enfermedad crítica y el estado vital al egreso. Se realizó un análisis de regresión logística para determinar los factores asociados de manera independiente con la mortalidad hospitalaria. Resultados: se analizaron 141 pacientes con SDRA, la mediana de edad fue 44 años y 62.9% fueron hombres. La primera causa de SDRA fue el choque séptico de origen pulmonar en 49.6% y el APACHE II tuvo una mediana de 18. La mediana de la PaO2/FIO2 al inicio del SDRA fue 91.5 y a las 72 horas fue 125. La mediana de PEEP requerido al inicio de la ventilación mecánica fue de 10 cmH2O y a las 72 horas fue de 12. La estancia en la UCI fue de 13 días y la mortalidad hospitalaria fue del 54%. Los factores asociados con mortalidad fueron el choque de origen pulmonar (OR = 2.45; IC 95% = 1.04-5.77) y el puntaje APACHE II (OR = 1.05 por cada punto; IC 95% = 1.003-1.1). El nivel de PEEP igual o menor en las primeras 72 horas se comportó como un factor protector (OR = 0.36; IC 95% = 0.16-0.82). Conclusiones: el SDRA tiene una alta mortalidad en nuestro medio y los factores más fuertemente asociados con dicha mortalidad son dependientes de la enfermedad de base y de la intensidad de la respuesta biológica a la misma. (Acta Med Colomb 2015; 40 305-309).

Introduction: acute respiratory distress syndrome (ARDS) is the most serious manifestation of acute pulmonary compromise. Currently no data are available to document the factors associated with mortality in our environment. Study Design: retrospective cohort study. Objective: To describe the factors associated with mortality in adult patients hospitalized in critical care unit with ARDS from January 2007 to December 2011. Methods: Data were collected with regard to causes of ARDS, hospital and ICU stay, critical illness severity and vital status at discharge. Logistic regression analysis was performed to determine factors independently associated with hospital mortality. Results: 141 patients with ARDS were analyzed; the median age was 44 years and 62.9% were men. The first cause of ARDS was septic shock of pulmonary origin in 49.6% and APACHE II had a median of 18. The median PaO2/FIO2 at the beginning of ARDS was 91.5 and at 72 hours was 125. The median PEEP required at the initiation of mechanical ventilation was 10 cmH2O and at 72 hours 12. The ICU stay was 13 days and hospital mortality was 54%. Factors associated with mortality were the shock of pulmonary origin (OR = 2.45; 95% CI = 1.04-5.77) and APACHE II (OR = 1.05 per point, 95% CI = 1.003-1.1). PEEP level equal to or less within 72 hours acted as a protective factor (OR = 0.36; 95% CI = 0.16-0.82). Conclusions: ARDS has a high mortality in our environment and the factors most strongly associated with this mortality are dependent on the underlying disease and the intensity of biological response to it.

Título: miR-139-5p protects septic mice with acute lung injury by inhibiting Toll-like receptor 4/Myeloid differentiation factor 88/Nuclear factor-&mac_kgr; B signaling pathway
Fonte: Clinics;76:e2484, 2021. tab, graf.
Idioma: en.
Resumo: OBJECTIVES: To investigate the role of miR-139-5p and the TLR4/MyD88/NF-κB signaling pathway in acute lung injury in septic mice. METHOD: A total of 140 healthy male SPF C57BL/6 mice were divided into seven groups, i.e., Normal, Control, NC, miR-139-5p mimic, miR-139-5p inhibitor, TAK-242, and miR-139-5p inhibitor+TAK-242 groups. The levels of miR-139-5p, proteins related to the TLR4/MyD88/NF-κB signaling pathway (TLR4, MyD88, and p-NF-κB p50), and MPO, SOD, GSH, and MDA in lung tissue were measured. The lung tissue wet-to-dry mass ratio (W/D), arterial oxygen partial pressure (PaO2), and carbon dioxide partial pressure (PaCO2) were measured. RESULTS: A web-based bioinformatic tool predicted that MyD88 was a target of miR-139-5p, which was verified by a dual luciferase reporter assay. Compared with those in the Normal group, the levels of miR-139-5p, PaO2, SOD, and GSH were significantly lower, while those of TLR4, MyD88, p-NF-κB p50, W/D, PaCO2, IL-1β, TNF-α, IL-6, MPO, and MDA were higher in all other groups. Moreover, compared with their levels in the Control group, these indicators exhibited contrasting results in the miR-139-5p mimic and TAK-242 groups, but were similar in the miR-139-5p inhibitor group. In the miR-139-5p inhibitor+TAK-242 group, acute lung injury, aggravated by miR-139-5p inhibitor, was partially rescued by TAK-242. CONCLUSION: miR-139-5p inhibits the TLR4/MyD88/NF-κB signaling pathway to alleviate acute lung injury in septic mice.

Título: Melatonin can be, more effective than N-acetylcysteine, protecting acute lung injury induced by intestinal ischemia-reperfusion in rat model
Fonte: Clinics;76:e2513, 2021. graf.
Idioma: en.
Resumo: OBJECTIVES: The current study compared the impact of pretreatment with melatonin and N-acetylcysteine (NAC) on the prevention of rat lung damage following intestinal ischemia-reperfusion (iIR). METHODS: Twenty-eight Wistar rats were subjected to intestinal ischemia induced by a 60 min occlusion of the superior mesenteric artery, followed by reperfusion for 120 min. Animals were divided into the following groups (n=7 per group): sham, only abdominal incision; SS+iIR, pretreated with saline solution and iIR; NAC+iIR, pretreated with NAC (20 mg/kg) and iIR; MEL+iIR, pretreated with melatonin (20 mg/kg) and iIR. Oxidative stress and inflammatory mediators were measured and histological analyses were performed in the lung tissues. RESULTS: Data showed a reduction in malondialdehyde (MDA), myeloperoxidase (MPO), and TNF-alpha in the animals pretreated with NAC or MEL when compared to those treated with SS+iIR (p<0.05). An increase in superoxide dismutase (SOD) levels in the NAC- and MEL-pretreated animals as compared to the SS+iIR group (34±8 U/g of tissue; p<0.05) was also observed. TNF-α levels were lower in the MEL+iIR group (91±5 pg/mL) than in the NAC+iIR group (101±6 pg/mL). Histological analysis demonstrated a higher lung lesion score in the SS+iIR group than in the pretreated groups. CONCLUSION: Both agents individually provided tissue protective effect against intestinal IR-induced lung injury, but melatonin was more effective in ameliorating the parameters analyzed in this study.

Título: Verification of the Effects of Red Light-emitting Diode Therapy on Acute Lung Injury in a Sepsis Model in Rats
Fonte: Braz. arch. biol. technol;63:e20180668, 2020. graf.
Idioma: en.
Resumo: Abstract The aim of this study was to evaluate the in vivo response of red light-emitting diode (LED) on acute lung injury (ALI) in a sepsis model in rats. Twenty rats were randomly allocated into two experimental groups (n=10): Control Sepsis Group (CS); sepsis and red LED group (SRL). The anterior region of the trachea and ventral regions of the chest (below the ribs), bilaterally were irradiated daily for two consecutive days, starting immediately after the surgery using red (630 nm) LED. The histological results showed that in red LED treated group presented a modulation of the lung inflammatory process, less intense alveolar septum thickening and decrease of the inflammatory cells. Moreover, LED significantly reduced the lung injury score and increased interleukin type 10 (IL-10) protein expression compared SG. These results suggest that LED was efficient in attenuating ALI in a sepsis model in rats by reducing inflammatory cells into lung tissue and enhancing the anti-inflammatory cytokine production.

Título: Effects of CpG oligodeoxynucleotide 1826 on acute radiation-induced lung injury in mice
Fonte: Biol. Res;49:1-6, 2016. ilus, graf.
Idioma: en.
Projeto: Shanghai Science and Technology Project.
Resumo: BACKGROUND: The radiation-induced lung injury is a common complication from radiotherapy in lung cancer. CpG ODN is TLR9 activator with potential immune modulatory effects and sensitization of radiotherapy in lung cancer. This study aimed to examine the effect of CpG ODN on acute radiation-induced lung injury in mice. METHODS AND RESULTS: The mouse model of radiation-induced lung injury was established by a single dose of 20 Gy X-rays exposure to the left lung. The results showed that the pneumonia score was lower in RT+CpG group than in RT group on 15th and 30th days. Compared with RT group, CpG ODN reduced the serum concentrations of MDA (P < 0.05) and increased the serum concentrations of SOD, GSH (P < 0.05). The serum concentration of TNF-α in RT+CpG group was lower on 15th and 30th days post-irradiation (P < 0.05). CONCLUSION: The study demonstrated that CpG ODN has preventive effects of acute radiation-induced lung injury in mice. Lung inflammatory reaction and oxidative stress are promoted in the initiation of radiation-induced pneumonia. CpG ODN may reduce the injury of reactive oxygen species and adjust the serum TNF-α concentration in the mice after irradiation, which reduces the generation of the inflammatory cytokines.

Resumo: The aim of this work was to measure HMGB1, TNF-alpha, and IL-8 in bronchoalveolar lavage (BAL), serum and TLR2 and TLR4mRNA expression in lung tissue of rabbits with two grades of acute lung injury (ALI). The animals were randomly assigned to groups with severe (S) and mild/moderate (MM) ALI, induced with warm saline, and a control group. HMGB1, TNF-alpha, IL-8, TLR2mRNA and TLR4mRNA were measured after ALI induction. The results showed increased levels of IL-8, TNF-alpha, HMGB1 and TLR4mRNA in the ALI groups. HMGB1, IL-8 and TNF-alpha concentrations in BAL were higher in S compared MM. Increased TLR4mRNA was observed in S and MM versus control. The results suggest an early participation of HMGB1 in ALI together with IL-8 and TNF-alpha and association with severity. TLR4 has early expression and role in ALI pathophysiology but is not associated with severity.(AU)

O objetivo deste trabalho é determinar os níveis de HMGB1, TNF-alfa e IL-8 no lavado broncoalveolar (BAL), bem como quantificar a expressão sérica de TLR2 e TLR4 mRNA em tecido pulmonar de coelhos com dois graus de lesão pulmonar aguda (LPA). Os animais foram distribuídos aleatoriamente em grupos com LPA grave (S) e leve / moderada (MM), induzidas com solução salina morna, e um grupo controle. HMGB1, TNF-alfa, IL-8, TLR2mRNA e TLR4mRNA foram medidos após a indução de LPA e quatro horas de ventilação mecânica. Os resultados mostraram níveis aumentados de IL-8, TNF-alfa, HMGB1 e TLR4mRNA nos grupos com LPA. As concentrações de HMGB1, IL-8 e TNF-alfa no LBA foram maiores no S comparado ao MM. Aumento de TLR4mRNA foi observado em S e MM versus controle. Os resultados sugerem uma participação precoce da HMGB1 na LPA em conjunto com IL-8 e TNF-alfa e associação com a gravidade da LPA. O TLR4 foi expresso na ALI e possivelmente possui papel precoce na fisiopatologia da LPA, mas sem associação com a gravidade.(AU)

Resumo: Abstract Purpose: Ischemia-reperfusion injury is one of the consequences of tourniquet application for extremity surgery. The aim of the study was to establish the effect of dexmedetomidine on the acute lung injury following lower extremity experimental ischemia-reperfusion model in rats. Methods: Twenty-eight Wistar-Albino breed Rats were recruited after Ethics Committee approval and allocated into 4 groups, each with 7 subjects. Group 1 (SHAM) received only anesthesia. Group 2 (IR) had experienced 3 h of ischemia and 3 h of reperfusion using left lower extremity tourniquet after anesthesia application. Groups 3 (D-50) and 4 (D-100) had undergone the same procedures as in the Group 2, except for receiving 50 and 100 mg·kg-1, respectively, dexmedetomidine intraperitoneally 1 h before the tourniquet release. Blood samples were obtained for the analysis of tumor necrosing factor-α and interleukin-6. Pulmonary tissue samples were obtained for histological analysis. Results: No significant difference regarding blood tumor necrosing factor-α and interleukin-6 values was found among the groups, whereas pulmonary tissue injury scores revealed significant difference. Histological scores obtained from the Group 2 were significantly higher from those in the Groups 1, 3 and 4 with p-values 0.001 for each comparison. Moreover, Group 1 scores were found to be significantly lower than those in the Groups 3 and 4 with p-values 0.001 and 0.011, respectively. No significant difference was observed between the Groups 3 and 4. Conclusion: Dexmedetomidine is effective in reduction of the experimental ischemia-reperfusion induced pulmonary tissue injury in rats, formed by extremity tourniquet application.

Resumo Objetivo: A lesão de isquemia-reperfusão é uma das consequências da aplicação do torniquete em cirurgias de extremidades. O objetivo do estudo foi determinar o efeito de dexmedetomidina em lesão pulmonar aguda após modelo experimental de isquemia-reperfusão em extremidade inferior de ratos. Métodos: Vinte e oito ratos albinos Wistar foram recrutados após aprovação do Comitê de Ética e alocados em quatro grupos, cada um com sete indivíduos. O Grupo 1 (Sham) recebeu apenas anestesia. O Grupo 2 (IR) foi submetido a 3 horas de isquemia e 3 horas de reperfusão com o uso de torniquete em extremidade inferior após a aplicação da anestesia. Os grupos 3 (D-50) e 4 (D-100) foram submetidos aos mesmos procedimentos do Grupo 2, exceto por receberem 50 e 100 mg.kg-1 de dexmedetomidina, respectivamente, por via intraperitoneal uma hora antes da liberação do torniquete. Amostras de sangue foram coletadas para análise de TNF-α e Interleucina-6 (IL-6). Amostras de tecido pulmonar foram coletadas para análise histológica. Resultados: Não houve diferença significativa quanto aos valores sanguíneos de TNF-α e IL-6 entre os grupos, enquanto os escores de lesão em tecidos pulmonares revelaram diferença significativa. Os escores histológicos obtidos no Grupo 2 foram significativamente maiores do que os dos grupos 1, 3 e 4, com valores-p de 0,001 para cada comparação. Além disso, os escores do Grupo 1 foram significativamente menores do que os dos grupos 3 e 4, com valores-p de 0,001 e 0,011, respectivamente. Não houve diferença significativa entre os grupos 3 e 4. Conclusão: Dexmedetomidina mostrou eficácia na redução de lesão em tecido pulmonar induzida por isquemia-reperfusão experimental em ratos, ocasionada por aplicação de torniquete em extremidade.

Resumo: The aim of this study was to evaluate the effects of single oral doses of D-005 (a lipid extract obtained from the fruit oil of Acrocomia crispa) on LPS-induced acute lung injury (ALI) in mice. D-005 batch composition was: lauric (35.8%), oleic (28.4%), myristic (14.2%), palmitic (8.9%), stearic (3.3%), capric (1.9%), caprylic (1.2%), and palmitoleic (0.05%) acids, for a total content of fatty acids of 93.7%. D-005 (200 mg/kg) significantly reduced lung edema (LE) (≈ 28% inhibition) and Lung Weight/Body Weight ratio (LW/BW) (75.8% inhibition). D-005 (25, 50, 100 and 200 mg/kg) produced a significant reduction of Histological score (59.9, 56.1, 53.5 and 73.3% inhibition, respectively). Dexamethasone, as the reference drug, was effective in this experimental model. In conclusion, pretreatment with single oral doses of D-005 significantly prevented the LPS-induced ALI in mice.

El objetivo de este estudio fue evaluar los efectos de dosis orales únicas de D-005 (extracto lipídico obtenido del aceite de frutos de Acrocomia crispa) sobre el daño pulmonar agudo (DPA) inducido por LPS en ratones. La composición del lote de D-005 fue: ácido láurico (35.8%), oleico (28.4%), mirístico (14.2%), palmítico (8.9%), esteárico (3.3%), cáprico (1.9%), caprílico (1.2%) y palmitoleico (0.05%), con un contenido total de ácidos grasos de 93.7%. D-005 (200 mg/kg) redujo significativamente el edema pulmonar (EP) (≈ 28% de inhibición) y la relación peso pulmón/peso corporal (PP/PC) (75.8% de inhibición). D-005 (25, 50, 100 y 200 mg/kg) produjo una reducción significativa de la puntuación histológica (59.9, 56.1, 53.5 y 73.3% de inhibición, respectivamente). La dexametasona, fármaco de referencia, fue efectiva en este modelo experimental. En conclusión, el pretratamiento con dosis orales únicas de D-005 previno significativamente el DPA inducido por LPS en ratones.

Resumo: Objetivo: Determinar la morbilidad y mortalidad de los pacientes con síndrome de distress respiratorio agudo (SDRA)/injuria pulmonar aguda (IPA) por Influenza A H1N1 que requirieron soporte cardiopulmonar en un hospital general. Material y métodos: Estudio retrospectivo, descriptivo, tipo serie de casos. Se revisaron las historias clínicas, las hojas de monitoreo ventilatorio y hemodinámico de los pacientes con SDRA/IPA secundario a Influenza A H1N1 atendidos en el Servicio de Cuidados Intensivos Generales (SCIG) del Hospital Nacional Cayetano Heredia entre mayo y setiembre de 2009. El diagnóstico de Influenza A H1N1 se realizó por PCR-RT. Resultados: Se atendieron 99 pacientes con Influenza A H1N1, 9 ingresaron al SCIG por SDRA/IPA; cinco requirieron ventilación mecánica invasiva (VMI), tres ventilación mecánica no invasiva y uno no requirió soporte ventilatorio. La edad promedio fue 43,3 ± 18,3 años; el tiempo de enfermedad 8 ± 3 días. Al ingreso, el 100% tuvo fiebre y disnea, el score APACHE II fue 10,5 ± 4,1 y el SOFA 5,6 ± 3,2; el Pa02/Fi02 96,74 ± 28,6. En 4/5 pacientes en VMI el Pa02/Fi02 a las 12 h y al final de la ventilación mecánica fue < 200. La presión en cuña estimada fue 15,69 ± 3,6 y el índice cardiaco por doppler esofágico 2,4 ± 0,34. La TGO fue 160 ± 152,15, DHL 2366,33 ± 1862,13 y CPK 216 ± 298,25. Todos los pacientes recibieron Oseltamivir 150 mg cada 12 h por 10 días. Cuatro pacientes fallecieron. Conclusiones: Los pacientes con SDRA/IPA por Influenza A H1 N1, fueron adultos jóvenes, con tiempo de enfermedad prolongado; con fiebre, disnea y linfopenia; sin compromiso cardiovascular y con hipoxemia refractaria como causa de muerte.

Objective: To determine the morbidity and mortality patterns of patients with acute respiratory distress syndrome (ARDS)/acute pulmonary injury (API) due to influenza A H1N1 who required cardiopulmonary support in a general hospital. Methods: Retrospective case series. Clinical charts, mechanical ventilation and hemodynamic monitoring charts of patients with ARDS/API due to influenza A H1N1 admitted to the general intensive care unit (GICU) of Hospital Nacional Cayetano Heredia from May to September 2009 were reviewed. The diagnosis of influenza H1N1 was confirmed with RT-PCR. Results: 99 patients with influenza A H1N1 were attended; 9 were admitted in the GICU with ARDS/API; five patients required invasive mechanical ventilation (IMV); three non-invasive mechanical ventilation (NIMV) and one did not require ventilatory support. Mean age was 43.3 ± 18.3 years; mean duration of symptoms was 8 ± 3 days. On admission, 100% of patients had fever and dyspnea; mean APACHE II score was 10.5 ± 4.1 and mean SOFA score was 5.6 ± 3.2; the mean Pa02/Fi02 was 96.74 ± 28.6. In 4/5 of patients requiring IMV the Pa02/Fi02 at 12 hours and at the end of mechanical ventilation was < 200. Estimated pulmonary wedge pressure was 15.69 ± 3.6 and the cardiac index estimated by esophageal doppler ultrasound was 2.4 ± 0.34. AST was 160 ± 152.15, LDH was 2366.33 ± 1862.13 and CK was 216 ± 298.25. All patients received oseltamivir 150 mg every 12 hours per 10 days. Four patients died. Conclusions: Patients with ARDS/API due to influenza A H1N1 were young adults with protracted disease with fever and lymphopenia, without cardiovascular involvement and with refractory hypoxemia as the main cause of death.

Resumo: El síndrome de dificultad respiratoria aguda incluye una compleja serie de acontecimientos que conducen a daño alveolar, edema pulmonar por aumento de la permeabilidad vascular e insuficiencia respiratoria; muchos procesos están relacionados con su aparición, la característica común es la activación de los neutrófilos en la circulación pulmonar o sistémica. Las manifestaciones clínicas aparecen generalmente 6 a 72 horas posterior al inicio del evento y empeoran rápidamente. El tratamiento se basa en un manejo interdisciplinario por parte del personal de la unidad de cuidados intensivos, se debe realizar un reconocimiento precoz de los pacientes descartando otras causas de hipoxemia, identificar y tratar la causa subyacente, y emplear la ventilación mecánica para asegurar correcta oxigenación, intentando siempre proteger los pulmones de la lesión pulmonar inducida por la técnica. La ventilación en decúbito prono favorece el aumento de la oxigenación en pacientes con este síndrome, los mecanismos que producen este incremento son probablemente múltiples e interdependientes y no han sido dilucidados en su totalidad. Es un procedimiento de bajo costo, recomendado implementar en pacientes categoría grave, y preferentemente en etapa tempana de la enfermedad, aunque es necesario realizar estudios futuros que puedan establecer el verdadero impacto en la mortalidad para evaluar su uso sistemático en todos los pacientes con Síndrome de Dificultad Respiratoria Aguda.

The Acute Respiratory Distress Syndrome involves a complex series of events leading to alveolar damage, pulmonary edema due to increased vascular permeability and respiratory failure; many processes are related to its appearance, the common feature is the activation of neutrophils in the pulmonary or systemic circulation. Clinical manifestations usually appear 6 to 72 hours after the event start the event and get worse quickly. The treatment is based on an interdisciplinary handling by the staff of the intensive care unit, making an early recognition of patients ruling out other causes of hypoxemia, identifying and treating the underlying cause, and using mechanical ventilation to ensure proper oxygenation and ventilation, always trying to protect the lungs from mechanical ventilation induced lung injury. Prone position ventilation promotes increased oxygenation in patients with this syndrome, the mechanisms that cause this increase are probably multiple and interdependent and have not been fully elucidated. It is a low-cost procedure, recommended in patient in serious category, and preferably in early stage of the disease. Future studies are needed that can establish the real impact on mortality to assess their systematic use in all patients with Acute Respiratory Distiess Syndrome. MÉD.UIS. 2016;29(2):81-101.
