Mortalidad de la sepsis en la unidad de cuidados intensivos / Mortality from sepsis in intensive care unit

INTRODUCCIÓN. La sepsis es un estado de disfunción multisistémica, que se produce por una respuesta desregulada del huésped a la infección. Diversos factores influyen en la gravedad, manifestaciones clínicas y progresión de la sepsis, tales como, heterogeneidad inmunológica y regulación dinámica de las vías de señalización celular. La evolución de los pacientes depende del tratamiento oportuno, las escalas de puntuación clínica permiten saber la mortalidad estimada. OBJETIVO. Evaluar la mortalidad en la unidad de cuidados intensivos; establecer el manejo y la utilidad de aplicar paquetes de medidas o "bundlers" para evitar la progresión a disfunción, fallo multiorgánico y muerte. METODOLOGÍA. Modalidad de investigación tipo revisión sistemática. Se realizó una búsqueda bibliográfica en bases de datos como Google académico, Mendeley, ScienceDirect, Pubmed, revistas como New England Journal Medicine, Critical Care, Journal of the American Medical Association, British Medical Journal. Se obtuvo las guías "Sobreviviendo a la sepsis" actualización 2021, 3 guías internacionales, 10 estudios observacionales, 2 estudios multicéntricos, 5 ensayos aleatorizados, 6 revisiones sistémicas, 5 metaanálisis, 1 reporte de caso clínico, 4 artículos con opiniones de expertos y actualizaciones con el tema mortalidad de la sepsis en UCI con un total de 36 artículos científicos. RESULTADOS. La mortalidad de la sepsis en la unidad de cuidados intensivos, fue menor en el hospital oncológico de Guayaquil, seguido de Australia, Alemania, Quito, Francia, Estados Unidos de Norteamérica y Vietnan, La mortalidad más alta se observa en pacientes con enfermedades del tejido conectivo. DISCUSIÓN. La aplicación de los paquetes de medidas o "bundlers" en la sepsis, se asocia con una mejor supervivencia y menores días de estancia hospitalaria. CONCLUSIÓN. Las escalas SOFA, APACHE II y SAPS II ayudan a predecir la mortalidad de forma eficiente, en la detección y el tratamiento temprano en pacientes con enfermedades agudas y de alto riesgo.

INTRODUCTION. Sepsis is a state of multisystem dysfunction, which is caused by a dysregulated host response to infection. Several factors influence the severity, clinical manifestations and progression of sepsis, such as immunological heterogeneity and dynamic regulation of cell signaling pathways. The evolution of patients depends on timely treatment, clinical scoring scales allow to know the estimated mortality. OBJECTIVE. To evaluate mortality in the intensive care unit; to establish the management and usefulness of applying bundlers to prevent progression to dysfunction, multiorgan failure and death. METHODOLOGY. Systematic review type research modality. A bibliographic search was carried out in databases such as Google Scholar, Mendeley, ScienceDirect, Pubmed, journals such as New England Journal Medicine, Critical Care, Journal of the American Medical Association, British Medical Journal. We obtained the guidelines "Surviving Sepsis" update 2021, 3 international guidelines, 10 observational studies, 2 multicenter studies, 5 randomized trials, 6 systemic reviews, 5 meta-analyses, 1 clinical case report, 4 articles with expert opinions and updates on the subject of sepsis mortality in ICU with a total of 36 scientific articles. RESULTS. The mortality of sepsis in the intensive care unit, was lower in the oncological hospital of Guayaquil, followed by Australia, Germany, Quito, France, United States of America and Vietnam, The highest mortality is observed in patients with connective tissue diseases. DISCUSSION. The application of bundlers in sepsis is associated with better survival and shorter days of hospital stay. CONCLUSIONS. The SOFA, APACHE II and SAPS II scales help to predict mortality efficiently in the early detection and treatment of patients with acute and high-risk disease.

Características epidemiológicas da mortalidade neonatal e infantil em uma regional de saúde / Epidemiological characteristics of neonatal and infant mortality in a health regional area

Objetivou-se analisar o perfil epidemiológico e as causas da mortalidade neonatal e infantil, em uma Regional de Saúde, de janeiro/2018 a agosto/2020. Trata-se de pesquisa exploratória, descritiva, transversal, retrospectivo, com abordagem quantitativa. A coleta de dados ocorreu em agosto de 2020, por meio de questionário elaborado pelas pesquisadoras, com base nas declarações de óbito disponibilizadas no Sistema de Informações de Mortalidade. O instrumento abordou as variáveis, sexo, raça, cor, idade da criança, idade materna, escolaridade materna, via de parto, idade gestacional, peso ao nascer, causa do óbito. Os dados foram submetidos à análise estatística descritiva e distribuição de frequência, por meio do Statistical Package for the Social Sciences (SPSS), versão 25.0. Constatou-se o predomínio de óbitos no sexo masculino (56,5%), de raça branca (87,8%), com equivalência entre extremo baixo peso e adequado (31,3%), com a principal causa de óbito por septicemia (13,9%). Quanto aos dados maternos, prevaleceram idade entre 21 e 30 anos de idade (45,2%) com gestação única (85,21%) e parto cesariano (65,2 %). Desses, 47,87% ocorreram no ano de 2018. Analisar os aspectos da mortalidade neonatal e infantil possibilita o planejamento e a readequação de ações no atendimento à saúde da criança, durante o período mais vulnerável e mais crítico dela, contribuindo, assim, para redução do número de óbitos.

This study analyzed the epidemiological profile and the causes of neonatal and infant mortality in a Health Regional Area between January 2018 and August 2020. This is an exploratory, descriptive, cross-sectional, retrospective study with a quantitative approach. Data collection took place during August 2020 through a questionnaire prepared by the researchers, based on the death certificates available in the Mortality Information System. The instrument included the variables of sex, race, color, child's age, mother's age, maternal education, childbirth mode, gestational age, birth weight, cause of death. The data were submitted to descriptive statistical analysis and frequency distribution using the Statistical Package for the Social Sciences (SPSS) version 25.0. There was a predominance of deaths among boys (56.5%), Caucasian (87.8%), with equivalence between extreme low and adequate weight (31.3%), with the main cause of death being septicemia (13.9%). As for maternal data, age between 21 to 30 years old (45.2%) prevailed, and 85.21% had a single pregnancy, with C-section childbirth (65.2%). From these, 47.87% occurred in 2018. It can be concluded that analyzing the aspects of neonatal and child mortality enables the planning and adjustment of actions in child health care during its most vulnerable and most critical period, thus contributing to reducing the number of deaths.

Use of non-conventional biomarkers in the early diagnosis of acute kidney injury in preterm newborns with sepsis / Biomarcadores não tradicionais de lesão renal aguda em recém-nascidos prematuros com sepse: diagnóstico precoce

Abstract Acute kidney injury (AKI) is a common finding in Neotatal Intensive Care Units (NICU). Sepsis is one the main causes of AKI in preterm newborns. AKI has been associated with significant death rates. Early detection of the condition is the first step to improving prevention, treatment, and outcomes, while decreasing length of hospitalization, care costs, and morbimortality. AKI may progress to chronic kidney disease (CKD), a condition linked with dialysis and greater risk of cardiovascular disease. This review article aims to discuss cases of AKI in preterm newborns with sepsis, the use of biomarkers in lab workup, and the use of non-conventional biomarkers for the early identification of AKI.

Resumo A lesão renal aguda (LRA) é comum na Unidade de Terapia Intensiva Neonatal (nUTI) e a sepse é uma de suas principais causas, especialmente em prematuros. Apresenta altas taxas de mortalidade e sua detecção precoce é o primeiro passo para a prevenção dessa condição, pois permite o tratamento adequado e melhora o desfecho, diminui o tempo de internação, os custos não médicos e a morbimortalidade. Destaca-se ainda que a LRA pode evoluir para doença renal crônica (DRC), havendo a necessidade de diálise, com maior risco de desenvolver doenças cardiovasculares. Este artigo de revisão tem como objetivo discutir a LRA em recém-nascidos (RNs) prematuros com sepse, abordando biomarcadores utilizados na rotina laboratorial e principalmente a utilização de biomarcadores não tradicionais para identificação precoce de LRA.

Analysis of trends in sepsis mortality in Brazil and by regions from 2010 to 2019 / Análise de tendência de mortalidade por sepse no Brasil e por regiões de 2010 a 2019

ABSTRACT OBJECTIVE To characterize the profile of inpatients and trend of sepsis mortality in the Brazilian Unified Health System (SUS), throughout Brazil, and in its regions separately, from 2010 to 2019. METHODS Observational, analytical and retrospective study of secondary data obtained through consultation to the Sistema de Informação Hospitalar (Hospital Information System). All incoming septicemia notifications from January 1, 2010 to December 31, 2019 were included. The following sociodemographic variables were used: sex, age, race, region and federative unit of residence. For data analysis, we used mortality and hospitalization coefficient, relative risk and Joinpoint regression. RESULTS There were a total of 1,044,227 cases of sepsis in Brazil, yielding a mean prevalence coefficient of 51.3/100 thousand inhabitants. There were 463,000 deaths from sepsis recorded, with a mean prevalence coefficient of 22.8 deaths/100,000 inhabitants. The highest rates occurred among the elderly, of brown race, and there was no significant difference between genders. The Southeast region accounted for the highest rates of hospitalization and deaths. A general trend toward increased mortality was observed in the period studied. CONCLUSION The heterogeneity of Brazil should be considered regarding socioeconomic and demographic characteristics, and differences in health investment and underreporting between regions, in order to understand the disease's epidemiological course. Finally, these findings should be correlated with other studies, in an effort to understand the behavior of the disease, and provide inputs for public and private policies in order to reduce the expressiveness of cases and deaths from sepsis in Brazil.

RESUMO OBJETIVO Caracterizar o perfil dos pacientes internados e a tendência de mortalidade por sepse no Sistema Único de Saúde (SUS), em todo Brasil e em suas regiões separadamente, entre os anos de 2010 e 2019. MÉTODOS Estudo observacional, analítico e retrospectivo de dados secundários obtidos por consulta ao Sistema de Informação Hospitalar. Foram incluídas todas as notificações por septicemia admitidas entre 1 de janeiro de 2010 e 31 de dezembro de 2019. Utilizou-se as variáveis sociodemográficas: sexo, idade, raça, região e unidade federativa de residência. Para a análise dos dados, utilizou-se coeficiente de mortalidade e de internação, risco relativo e regressão por Joinpoints. RESULTADOS Totalizaram-se 1.044.227 casos de sepse no país, perfazendo um coeficiente de prevalência média de 51,3/100 mil habitantes. Foram registrados 463 mil óbitos por sepse, com coeficiente médio de 22,8 óbitos/100 mil habitantes. As maiores taxas ocorreram entre os idosos, de raça parda e não houve uma diferença significativa entre os sexos. A Região Sudeste foi responsável pelo maior índice de internação e óbitos. Observou-se uma tendência geral de aumento da mortalidade no período estudado. CONCLUSÃO Cabe considerar a heterogeneidade do Brasil, no que concerne às características socioeconômicas e demográficas e às diferenças de investimento em saúde e de subnotificações entre as regiões, a fim de entender o traçado epidemiológico da doença. Por fim, é necessário correlacionar esses achados com demais estudos, buscando entendimento do comportamento da doença e embasamento para políticas públicas e privadas, com intuito de diminuir a expressividade de casos e óbitos por sepse no país.

Mortalidad por sepsis neonatal entre los años 2016 y 2020 en Chile: una mirada nacional / Mortality due to neonatal sepsis between 2016 and 2020 in Chile: a national perspective

Introducción: La sepsis neonatal (SN) es una infección sistémica que ocurre antes de los 90 días de vida y que representa una amenaza potencialmente mortal. Esta investigación busca describir la tendencia de defunción por SN en Chile, durante el periodo 2016-2020. Materiales y métodos: Estudio descriptivo observacional, que incluyó a niños fallecidos por SN (n=249) en el periodo 2016-2020 en Chile según datos del departamento de estadísticas e información de salud de Chile. Las variables estudiadas fueron: año de fallecimiento, grupo etario, sexo, región y agente etiológico. No se requirió comité de ética. Resultados: El 2020 tuvo la menor tasa de mortalidad por SN (0,17) y el 2017 la mayor (0,31). El grupo etario de 0-2 días de nacido tuvo la mayor tasa de mortalidad (0,07), mientras que el grupo de 27-28 días corresponde a la menor (0,00). La región de Antofagasta tuvo la mayor mortalidad (0,44) y la región de Magallanes la menor (0,11). La tasa de mortalidad promedio en hombres corresponde a 0,12 y en mujeres a 0,10. En el 89,16% de los casos no se identificó el agente etiológico. Discusión: La mayor mortalidad en 2017 podría deberse a una proporción más alta de nacimientos pretérmino en dicho año. La mayor cantidad de defunciones a menor edad cronológica estaría relacionada con su inmadurez inmunológica. La no detección del agente etiológico pudo deberse al bajo rendimiento de los hemocultivos. Sin embargo, faltan más investigaciones acerca de la incidencia y mortalidad por sepsis neonatal.

Introduction: Neonatal sepsis (NS) is a systemic infection that occurs before 90 days of life and represents a life-threatening threat. This research seeks to describe the trend of death by NS in Chile, during the period 2016-2020. Materials and methods: Observational descriptive study, which included children who died due to NS (n=249) in the period 2016-2020 in Chile, according to data from the Department of Statistics and Health Information of Chile. The variables studied were: year of death, age group, sex, region and etiological agent. No ethics committee was required. Results: 2020 had the lowest mortality rate due to NS (0.17) and 2017 the highest (0.31). The age group of 0-2 days of birth had the highest mortality rate (0.07), while the group of 27-28 days corresponds to the lowest (0.00). The Antofagasta region had the highest mortality (0.44) and the Magallanes region the lowest (0.11). The average mortality rate in men corresponds to 0.12 and in women to 0.10. In 89.16% of the cases, the etiological agent was not identified. Discussion: The higher mortality in 2017 could be due to a higher proportion of preterm births in that year. The greater number of deaths at a lower chronological age would be related to their immunological immaturity. The non-detection of the etiological agent could be due to the low yield of the blood cultures. However, more research on the incidence and mortality from neonatal sepsis is lacking.

Sepsis mortality and the Human Development Index in Brazilian capitals: 1990-2016 / Mortalidade por sepse e Índice de Desenvolvimento Humano nas capitais brasileiras: 1990-2016 / Mortalidad por sepsis e Índice de Desarrollo Humano en las capitales brasileñas: 1990-2016

Background and Objectives: the Human Development Index is among the determinants associated with access to health services and sepsis assistance. This study aimed to describe the frequency of mortality from sepsis in Brazilian capitals and verify its correlation with the Human Development Index (HDI), in three-year periods that represented from the early 90's to 2016. Methods: a time series ecological epidemiology study, with consultation in secondary database involving Brazilian capital variables, population, deaths from sepsis and HDI. Correlation was assessed with Pearson's/Spearman's correlation coefficient. Results: the three highest mean coefficients of mortality from sepsis were observed in Rio Branco (9082.50), Manaus (6367.25) and Macapá (6085.25). A significant correlation was found between the mean mortality rate and the mean HDI in Aracaju (-0,999; p=0.001), Brasília (-0,991; p=0.009), Campo Grande (-0,977; p=0.023), Cuiabá (-0.983; p=0.017), Florianópolis (0.999; p=0.001), Goiânia (-0.997; p=0.003), Maceió (-0.987; p=0.013), Natal (-0.962; p=0.038), Palmas (-0.982; p=0.018) and Vitória (-0.998; p=0.002). Conclusion: there is a general correlation between the mean mortality coefficients and HDI. As HDI increases, there is a decrease in mortality from sepsis.(AU)

Introducción: los cristaloides son medicamentos usados en pacientes críticamente enfermos, con resultados ambiguos cuando se utilizan soluciones balanceadas versus solución salina normal. Objetivo: conocer si existen diferencias al usar solución salina 0.9% vs. lactato de Ringer en pacientes críticamente enfermos con sepsis y choque séptico o hipovolémico, en cuanto a mortalidad, lesión renal aguda y tiempo de estancia hospitalaria. Métodos: estudio observacional de tipo cohorte retrospectiva en mayores de 18 años con diagnóstico de sepsis, choque séptico o hipovolémico. Se excluyeron aquellos con enfermedad renal crónica en diálisis, las hospitalizadas por ginecología/obstetricia y aquellos con diagnóstico de muerte encefálica o donantes de órganos. Se evaluaron los desenlaces primarios de mortalidad, lesión renal aguda y estancia hospitalaria. Resultados y discusión: se incluyeron 314 pacientes, 158 en el grupo expuesto a solución salina al 0.9% y 156 con lactato de Ringer. Se presentó lesión renal aguda en 22.7% con solución salina y 25.8% con lactato de Ringer (OR 1.18 IC 95%:0.7-2). La mortalidad con solución salina fue de 49%, y en lactato 49% (OR 1.01 IC 95%:0.63-1.63). Los factores de riesgo identificados para mortalidad fueron uso de soporte vasopresor (OR 35 IC 95% 12-83) y lesión renal aguda (1.3 IC 95% 1.01-1.69). Conclusiones: en el paciente críticamente enfermo con sepsis, choque séptico o hipovolémico el uso desolución salina 0.9% no representa diferencias al compararlo con lactato de Ringer en cuanto a mortalidad, lesión renal aguda o estancia hospitalaria. La elección de un cristaloide debe ser individualizada, teniendo en cuenta las comorbilidades, la presencia de hipercloremia o hiperpotasemia.

Objective: crystalloids are drugs used in critically ill patients, with ambiguous results when balanced solutions versus normal saline solution (NS) are used. The objective of this study is to determine if there are differences when NS (0.9%) vs. lactated Ringer ́s (LR) solution are given to critically ill patients in sepsis or septic or hypovolemic shock, in terms of mortality, acute renal injury and length of hospital stay. Methods: a retrospective observational cohort study in patients over 18 years old with sepsis or septic or hypovolemic shock. Patients with chronic renal disease on dialysis, those hospitalized by gynecology/obstetrics and those diagnosed with brain death or organ donors were excluded. The primary mortality outcomes, acute renal injury and hospital stay were evaluated. Results: 314 patients were included, 158 in the NS group and 156 in the LR group. Acute renal injury occurred in 22.7% in the NS group and 25.8% in the LR group (OR 1.18 IC 95%:0.7-2). Mortality rate was 49% in the NS group and 49% in the LR group (OR 1.01 95%: CI 0.63-1.63). Mortality risk factors included the use of vasopressor support (OR 35 95% CI 12-83) and acute renal injury (1.3 95% CI 1.01-1.69). Conclusions: no difference was found with the use of NS in critically ill patients with sepsis or septic or hypovolemic shock when compared with LR in terms of mortality, acute renal injury or hospital stay. The choice of which crystalloid to administer should be individualized, based on the comorbidities and the presence of hyperchloremia or hyperkalemia.

Clinical significance of sirtuin 1 level in sepsis: correlation with disease risk, severity, and mortality risk

This study aimed to investigate the value of sirtuin 1 (SIRT1) in differentiating sepsis patients from healthy controls (HCs), and its correlation with inflammation, disease severity, as well as prognosis in sepsis patients. Serum samples were collected from 180 sepsis patients and 180 age- and gender-matched HCs. The SIRT1 level in the serum samples was detected by enzyme-linked immunoassay. The clinical data of the sepsis patients were documented, and their disease severity scores and 28-day mortality rate were assessed. SIRT1 was decreased in sepsis patients compared with HCs, and the receiver operating characteristic curve (ROC) showed that SIRT1 distinguished sepsis patients from HCs (area under the curve (AUC): 0.901; 95% confidence interval (CI): 0.868-0.934). In sepsis patients, SIRT1 negatively correlated with serum creatinine (Scr), white blood cells (WBC), C-reactive protein (CRP), acute physiology, and chronic health evaluation II (APACHE II) score, and sequential organ failure assessment (SOFA) score, while it positively correlated with albumin. No correlation of SIRT1 with primary infection site or primary organism was observed. Furthermore, SIRT1 was reduced in 28-day non-survivors compared with 28-day survivors, and subsequent ROC showed that SIRT1 predicted 28-day mortality of sepsis patients (AUC: 0.725; 95% CI: 0.651-0.800), and its prognostic value was not inferior to Scr, albumin, WBC, and CRP, but was less than SOFA score and APACHE II score. In conclusion, measurement of serum SIRT1 might assist with the optimization of disease assessment, management strategies, and survival surveillance in sepsis patients.

Experiencia en shock séptico en emergencias. Factores asociados a falta de respuesta a fluídos / Experience in septic shock in Emergencies. Factors associated with lack of response to fluid resuscitation

Introducción: La sepsis es una de las principales causas de muerte infantil a nivel mundial. Las guías de tratamiento utilizadas en nuestro servicio se basan en parámetros clínicos para un soporte hemodinámico temprano con énfasis en el uso de fluidos e inotrópicos guiados por metas clínicas. Objetivos: Describir las características epidemiológicas y clínicas en una cohorte de niños con diagnóstico de shock séptico (SS) en el área de emergencias, controlando tasa de respuesta a fluidos, mortalidad y su relación con las características de los pacientes. Materiales y métodos: Estudio observacional de cohorte prospectivo entre Julio del 2009 y Julio del 2010. Se incluyeron 83 pacientes entre 0 a 18 años que cumplieron con los criterios diagnósticos de SS. La respuesta a volumen se definió como: respondedores (RE) a los pacientes que solo requirieron expansión con volumen y no respondedores (nRE) a aquellos que requirieron inotrópicos luego de llegar a 60 ml/kg o aparición de signos de sobrecarga cardíaca. Resultados: 64% fueron varones con mediana de edad de 5,8 años (RIC 2-12). 71% presentaban alguna enfermedad crónica preexistente, siendo 40% pacientes oncológicos. El 25 % requirió asistencia respiratoria mecánica y 65% inotrópicos. La mediana de estadía hospitalaria fue 10 días (RIC 7-16 días). Un 35% fue RE. Solo la hipotensión al ingreso resultó ser factor de riesgo para nRE (p0,035), pero en el modelo multivariado no resultó estadísticamente significativo. El 8% de los pacientes fallecieron. Conclusiones: En nuestra población, los pacientes con enfermedades oncológicas representan un número importante de los casos de SS y posiblemente tengan una mayor mortalidad. La tasa de respuesta a volumen ocurrió en 35% de los casos. La hipotensión inicial constituye un probable factor de riesgo para nRE (AU)

Introduction: Sepsis is one of the main causes of childhood death worldwide. Treatment guidelines used at our department are based on clinical parameters for early hemodynamic support with emphasis on fluid resuscitation and inotropics use guided by clinical goals. Objectives: To describe the epidemiologic and clinical features of a cohort of children with septic shock (SS) seen at the emergency department evaluating response rate to fluid resuscitation and mortality related to patient characteristics. Materials and methods: A prospective, observational cohort study was conducted between July 2009 and July 2010. Overall, 83 patients between 0 and 18 years of age that met the diagnostic criteria of SS were included. Response to fluid resuscitation was defined as: responders (RE), those patients that only required volume expansion, and non-responders (nRE), those that required inotropes after having reached 60 ml/kg or appearance of signs of fluid overload. Results: 64% were boys; median age was 5.8 years (IQR 2-12); 71% had some type of preexisting chronic disease, consisting of cancer in 40%. Overall, 25% required mechanical ventilation and 65% inotropes. Median length of hospital stay was 10 days (IQR 7-16 days). 35% of the patients were RE. Only hypotension on admission was found to be a risk factor for nRE (p 0.035); however, in a multivariate model, this finding did not show to be statistically significant. Eight percent of the patients died. Conclusions: In our cohort, patients with cancer accounted for a large number of those who developed SS; in these patients mortality may be increased. Response rate to fluid resuscitation was 35%. Initial hypotension may be a risk factor for nRE.

Afectación respiratoria por coronavirus (COVID-19) / Respiratory involvement by coronavirus (COVID-19)

In December 2019, an epidemic of cases with unexplained lower respiratory infections detected in Wuhan, China was first reported to the WHO China Office. The respiratory picture presents in various ways, from asymptomatic or paucisymptomatic forms, to clinical conditions characterized by respiratory failure that require mechanical ventilation and support in the ICU, with multi-organ and systemic manifestations in terms of sepsis, septic shock and multiple organ dysfunction syndromes. The etiological agent was identified as a virus belonging to the coronavirus family (CoV) with a high contagion capacity that determined its rapid spread, triggering a pandemic with high morbidity and mortality. This review attempts to address the basics of this disease.

Volumen plaquetario medio como predictor de la mortalidad en pacientes con sepsis: revisión sistemática y metanálisis / Mean platelet volume as a predictor of mortality in patients with sepsis: systematic review and meta-analysis

Introducción: El volumen medio plaquetario (VMP) es un biomarcador utilizado en el abordaje integral de la sepsis. Objetivo: Evaluar la asociación entre VMP con la mortalidad en pacientes con sepsis. Métodos: Se realizó una revisión sistemática de estudios observacionales en cinco bases de datos. Se analizó la mortalidad asociada con la sepsis; las intervenciones consideradas fueron VMP, APACHE y lactato sérico. Resultados: Respecto a la mortalidad asociada a sepsis, se encontró un valor significativo en la VMP a las 72 horas (200 fallecidos versus 654 no fallecidos; MD 0.83 IC95% 0.53-1.13, p=< 0.0001, I2 =72.9%); así como el valor de APACHE II (220 muertos frente a 604 no fallecidos; MD 0.81 IC95% 0.62-1.0, p= 0.0001, I2 =32%). No se encontró significancia estadística para las demás variables clínicas. Conclusiones: El aumento de la VMP se asocia con mayor riesgo de mortalidad en pacientes con sepsis, especialmente después de 72 horas de evolución de las características clínicas.

Introduction: Platelet mean volume (MVP) is a biomarker used in the integral approach to sepsis. Objective: To assess the association between MVP and mortality in patients with sepsis. Methods: A systematic review of observational studies in five databases was performed. Mortality associated with sepsis was analysed; interventions considered were MPV, APACHE and serum lactate. Results: Regarding mortality associated with sepsis, a significant value was found in the MVP at 72 hours (200 deceased versus 654 not deceased; MD 0.83 IC95% 0.53-1.13, p=<0.0001, I2 =72.9%); as well as the value of APACHE II (220 dead versus 604 not deceased; MD 0.81 IC95% 0.62-1.0, p= 0.0001, I2 =32%). No statistical significance was found for the other clinical variables. Conclusions: Increased MVP is associated with increased risk of mortality in patients with sepsis, especially after 72 hours of evolution of clinical features.

Tempo para evacuação de foco séptico abdominal e mortalidade em portadores de sepse / Time to clearance of abdominal septic focus and mortality in patients with sepsis

RESUMO Objetivo: Aferir a relação entre tempo para evacuação de foco e mortalidade hospitalar em portadores de sepse e choque séptico. Métodos: Estudo observacional, unicêntrico, com análise retrospectiva do tempo para evacuação de foco séptico abdominal. Os pacientes foram classificados conforme o tempo para evacuação do foco em grupo precoce (≤ 12 horas) ou tardio (> 12 horas). Resultados: Foram avaliados 135 pacientes. Não houve associação entre tempo para evacuação do foco e mortalidade hospitalar (≤ 12 horas versus > 12 horas): 52,3% versus 52,9%, com p = 0,137. Conclusão: Não houve diferença na mortalidade hospitalar entre pacientes com sepse ou choque séptico que tiveram foco infeccioso evacuado antes ou após 12 horas do diagnóstico de sepse.

ABSTRACT Objective: To assess the relationship between time to focus clearance and hospital mortality in patients with sepsis and septic shock. Methods: This was an observational, single-center study with a retrospective analysis of the time to clearance of abdominal septic focus. Patients were classified according to the time to focus clearance into an early (≤ 12 hours) or delayed (> 12 hours) group. Results: A total of 135 patients were evaluated. There was no association between time to focus clearance and hospital mortality (≤ 12 hours versus > 12 hours): 52.3% versus 52.9%, with p = 0.137. Conclusion: There was no difference in hospital mortality among patients with sepsis or septic shock who had an infectious focus evacuated before or after 12 hours after the diagnosis of sepsis.

Predictors of mortality among patients with acute leukemias admitted to an intensive care unit specialized in patients with hematological disease at a Brazilian hospital

Abstract Introduction Hematologists deal every day with high mortality rates of acute leukemia patients. Many times these patients need Intensive Care Unit (ICU) support and some general ICU teams believe that these patients have a much greater chance of dying than patients with other pathologies. In Brazil, data related to mortality rates and ICUs for acute leukemia patients are scarce. Methods Therefore, to assess mortality predictors in patients with acute leukemia admitted to a specialized hematological ICU, we evaluated demographics, supportive care, hospitalization time, disease status, admitting diagnosis, neutropenia, number of transfusions and Acute Physiology and Chronic Health Evaluation (APACHE)/Sepsis Related Organ Failure Assessment (SOFA) scores as possible factors associated with mortality. Data were extracted from the first admission records of 110 patients with acute leukemia admitted to the Hemocentro de Pernambuco (Hemope) ICU between 2006 and 2009. Results In this retrospective cohort study, 72/110 of the patients were men, and 64/110 were from the metropolitan area of Recife. The patients' age median was 43.5 years (±17.9); 67.3% had acute myeloid leukemia (AML) and 32.7% had acute lymphoid leukemia. The main admitting diagnosis in the ICU was sepsis (66.7%). The mean APACHE II score was 18.3. Of the total, 65 (59%) died, and the mortality rate was independently related to longer hospitalization (p < 0.001), the increase in the APACHE II score (p < 0.038) and having received hemodialysis (p < 0.006). Neutropenia, receiving multiple transfusions and using any kind of mechanical ventilation or vasoactive drug on admission were not relevant to mortality. Factors associated with higher mortality rates were: longer hospitalization, increase in the APACHE II score, and use of hemodialysis. Conclusion With these data, to prevent organ lesions before admission to the ICU, a better strategy might be to reduce mortality for leukemia patients.

Estratificação para predizer a resposta ao tratamento antioxidante em terapia intensiva: um estudo translacional / Stratification to predict the response to antioxidant

RESUMO Objetivo: Avaliar a efetividade da estratificação para identificar e escolher alvos para terapia antioxidante em um modelo de sepse letal em animais e pacientes que desenvolveram hipotensão prolongada. Métodos: Submeteu-se um grupo de ratos à sepse induzida por ligadura e punção do ceco. Os animais foram divididos em dois grupos: os com níveis plasmáticos altos e os com níveis plasmáticos baixos de interleucina-6. Após a estratificação, administrou-se aos animais N-acetilcisteína mais desferroxamina ou soro fisiológico a partir de 3 e 12 horas após a cirurgia. Em pacientes hipotensos, N-acetilcisteína mais desferroxamina ou placebo foram administrados dentro de 12 horas após o cumprimento dos critérios para inclusão. Resultados: O uso de N-acetilcisteína mais desferroxamina aumentou a sobrevivência no modelo com ligadura mais punção do ceco quando a administração ocorreu 3 e 12 horas após indução da sepse. Ao utilizar os níveis de interleucina-6 para separar os animais que receberam antioxidantes, o efeito protetor só foi observado nos animais que tinham níveis elevados de interleucina-6. O efeito antioxidante de N-acetilcisteína mais desferroxamina foi similar nos dois grupos, porém observou-se diminuição significante dos níveis plasmáticos de interleucina-6 no grupo que apresentava elevado nível de interleucina-6. Em comparação com pacientes tratados com antioxidantes no subgrupo que tinha baixos níveis plasmáticos de interleucina-6, aqueles que tinham níveis elevados de interleucina-6 tiveram menor incidência de lesão renal aguda, porém não foram diferentes em termos de severidade da lesão renal aguda ou da mortalidade na unidade de terapia intensiva. Conclusão: Direcionar a terapia antioxidante para um elevado fenótipo inflamatório selecionaria uma população responsiva.

ABSTRACT Objective: To examine the effectiveness of stratification to identify and target antioxidant therapy for animal models of lethal sepsis and in patients who develop sustained hypotension. Methods: Rats were subjected to sepsis induced by cecal ligation and puncture. Animals were divided into two groups: those with high and low plasma levels of interleukin-6. Following stratification, N-acetylcysteine plus deferoxamine or saline was administered to animals starting 3 and 12 hours after surgery. N-Acetylcysteine plus deferoxamine or placebo was administered within 12 hours of meeting the inclusion criteria in hypotensive patients. Results: N-Acetylcysteine plus deferoxamine increased survival in the cecal ligation and puncture model when administered 3 and 12 hours after sepsis induction. When dividing animals that received antioxidants using plasma interleukin-6 levels, the protective effect was observed only in those animals with high IL-6 levels. The antioxidant effect of N-acetylcysteine + deferoxamine was similar in the two groups, but a significant decrease in plasma interleukin-6 levels was observed in the high-interleukin-6-level group. Compared with patients treated with antioxidants in the low-interleukin-6 subgroup, those in the high-interleukin-6 subgroup had a lower incidence of acute kidney injury but were not different in terms of acute kidney injury severity or intensive care unit mortality. Conclusion: Targeting antioxidant therapy to a high inflammatory phenotype would select a responsive population.

Epidemiología del shock séptico en un servicio de atención médica prehospitalaria en cinco ciudades colombianas / Epidemiology of septic shock in prehospital medical services in five Colombian cities

RESUMEN Objetivo: Explorar la asociación entre factores demográficos y clínicos con la presentación de shock séptico en pacientes atendidos en un servicio prehospitalario de emergencias en cinco ciudades colombianas entre los años 2015-2016. Métodos: Estudio de corte transversal con recolección retrospectiva de datos. Se recolectó información clínica y demográfica de las historias clínicas de pacientes con diagnóstico de sepsis que recibieron atención prehospitalaria en cinco ciudades colombianas en los años 2015 y 2016. Se realizó una verificación del diagnóstico de shock séptico en el 20% de los casos, dando origen a dos escenarios analizados: observado y verificado. Se analizó la asociación con pruebas de Chi cuadrado, t de Student y finalmente con un modelo de regresión logística ajustado. Se consideró covariables significativas aquellas con p < 0,05. Resultados: Se presentó una mayor frecuencia del evento en mujeres (62,6%) y en mayores de 80 años (64,5%), sin ser factores diferenciadores para shock séptico. El foco infeccioso más común fue urinario. En el escenario observado, los mayores de 60 años (RP: 3,22; IC95%: 1,45 - 35,01) y el antecedente de cáncer fueron las características asociadas con el shock séptico (RP: 1,20; IC95%: 1,2 - 12,87), mientras que en el grupo verificado fueron la enfermedad pulmonar obstructiva crónica (RP: 1,99; IC95%: 1,26 - 7,14), el antecedente de cáncer (RP: 1,15; IC95%: 1,11 - 6,62) y presencia de hipovolemia (RP: 1,41; IC95%: 1,02 - 5,50). Conclusión: Los factores de riesgo más importantes para shock séptico en pacientes de atención prehospitalaria en cinco ciudades colombianas fueron las enfermedades oncológicas, las pulmonares e hipovolemia.

ABSTRACT Objective: To explore the association between demographic and clinical factors and the presentation of septic shock in patients treated by prehospital emergency services in five Colombian cities between 2015 and 2016. Methods: This was a cross-sectional study with retrospective data collection. Clinical and demographic data were collected from the medical records of patients diagnosed with sepsis who received prehospital care in five Colombian cities in 2015 and 2016. The diagnosis of septic shock was checked in 20% of the cases, generating two analyzed scenarios: observed and verified. Data were analyzed using the chi-square test, Student's t test and an adjusted logistic regression model. Covariates with p < 0.05 were considered significant. Results: There was a higher frequency of septic shock in women (62.6%) and in individuals older than 80 years (64.5%), but these were not differentiating factors for septic shock. The most common source of infection was the urinary tract. In the observed scenario, age over 60 (prevalence ratio (PR): 3.22; 95% confidence interval (CI): 1.45 - 35.01) and history of cancer (PR: 1.20; 95%CI: 1.2 - 12.87) were the characteristics associated with septic shock, whereas in the verified scenario, chronic obstructive pulmonary disease (PR: 1.99; 95%CI: 1.26 - 7.14), history of cancer (PR: 1.15; 95%CI: 1.11 - 6.62) and presence of hypovolemia (PR: 1.41; 95%CI: 1.02 - 5.50) were observed. Conclusion: The most important risk factors for septic shock in prehospital care patients in five Colombian cities were oncological and pulmonary diseases and hypovolemia.
