Shock séptico: complicación atípica de duplicación del tracto alimentario / Septic shock: an atypical complication of alimentary tract duplication

Las duplicaciones del tracto alimentario son un conjunto heterogéneo de anomalías congénitas del tubo digestivo. Su forma de presentación es variada, y pueden desarrollar distintas complicaciones libradas a su evolución natural. La infección es una complicación poco frecuente, pero que no puede desconocerse por la gravedad que implica. Se presenta el caso de una paciente de 2 años de edad, previamente sana, con una complicación atípica de una duplicación del tracto alimentario: un shock séptico. Consultó inicialmente por distensión y dolor abdominal asociado a una masa abdominal palpable. Los estudios imagenológicos evidenciaron una formación líquida parcialmente tabicada en el hemiabdomen derecho. Durante la internación, se presentó una infección intratumoral, que evolucionó al shock séptico. Respondió favorablemente al tratamiento médico del shock, y se realizó la exéresis quirúrgica posteriormente. La anatomía patológica confirmó la duplicación del tracto alimentario.

Alimentary tract duplications are heterogenous congenital anomalies of the digestive tract. Their form of presentation is varied, and they may lead to different complications, depending on their natural course. Infection is a rare complication, but it cannot be ignored because of its severity. Here we describe the case of an otherwise healthy 2-year-old girl with an atypical complication of alimentary tract duplication: septic shock. She initially consulted due to abdominal distension and pain associated with a palpable abdominal mass. The imaging studies showed a partial fluid septation in the right side of the abdomen. During hospitalization, an intratumoral infection developed, which progressed to septic shock. The patient responded favorably to medical treatment for shock, and surgical resection was subsequently performed. The pathology report confirmed the presence of alimentary tract duplication.

Significado biológico y utilidad clínica del lactato en la sepsis / Biological significance and clinical utility of lactate in sepsis

La sepsis es un problema global de salud y la progresión hacia el shock séptico se asocia con un incremento marcado de la morbimortalidad. En este escenario, el aumento del lactato plasmático demostró ser un indicador de gravedad y un predictor de mortalidad, y suele interpretarse casi exclusivamente como marcador de baja perfusión tisular. Sin embargo, últimamente se produjo un cambio de paradigma en la exégesis del metabolismo y propiedades biológicas del lactato. En efecto, la adaptación metabólica al estrés, aun con adecuado aporte de oxígeno, puede justificar la elevación del lactato circulante. Asimismo, otras consecuencias fisiopatológicas de la sepsis, como la disfunción mitocondrial, se asocian con el desarrollo de hiperlactatemia sin que necesariamente se acompañen de baja perfusión tisular. Interpretar el origen y la función del lactato puede resultar de suma utilidad clínica en la sepsis, especialmente cuando sus niveles circulantes fundamentan las medidas de reanimación.

Sepsis is a global health problem; progression to septic shock is associated with a marked increase in morbidity and mortality. In this setting, increased plasma lactate levels demonstrated to be an indicator of severity and a predictor of mortality, and are usually interpreted almost exclusively as a marker of low tissue perfusion. However, a recent paradigm shift has occurred in the exegesis of lactate metabolism and its biological properties. Indeed, metabolic adaptation to stress, even with an adequate oxygen supply, may account for high circulating lactate levels. Likewise, other pathophysiological consequences of sepsis, such as mitochondrial dysfunction, are associated with the development of hyperlactatemia, which is not necessarily accompanied by low tissue perfusion. Interpreting the origin and function of lactate may be of great clinical utility in sepsis, especially when circulating lactate levels are the basis for resuscitative measures.

Desempenho do óxido nítrico na sepse: uma revisão de escopo / Desempeño del óxido nítrico en la sepsis: una revisión de alcance / Performance of nitric oxide in sepsis: a scoping review

Resumo Objetivo Mapear as evidências disponíveis sobre as ações do óxido nítrico na fisiopatologia da sepse e sua relação com a gravidade de pacientes sépticos. Método Revisão de escopo de acordo com a metodologia do Joanna Briggs Institute. Realizou-se busca por estudos que evidenciaram as ações do óxido nítrico na sepse e se o seu aumento está associado à gravidade de pacientes sépticos. Dois revisores independentes fizeram o mapeamento das informações utilizando um instrumento de extração de dados previamente elaborado. Os dados foram analisados quanto à sua relevância, sendo posteriormente extraídos e sintetizados. Resultados De 1342 estudos, 11 foram incluídos na revisão. O primeiro foi publicado em 2017 e o último, em 2022. A maioria foi desenvolvida nos Estados Unidos, na China e na Alemanha. Os estudos apresentaram informações referentes as ações do óxido nítrico, sintetizando sua biodisponibilidade e os inibidores endógenos relacionados a sua produção, além de abordarem a relação do óxido nítrico com a gravidade da sepse. Conclusão A produção de óxido nítrico fisiológico durante a sepse atua como protetor vascular, principalmente na microcirculação, porém, em altas concentrações, contribui para a disfunção vascular, que subverte a fisiologia da regulação da pressão arterial, causando profunda vasodilatação e hipotensão refratária e aumentando a gravidade de pacientes sépticos.

Abstract Objective Map the available evidence on the actions of nitric oxide in the pathophysiology of sepsis and its relationship with the severity of sepsis in patients. Method Scoping review following the Joanna Briggs Institute methodology. A search was carried out for studies that highlighted the actions of nitric oxide in sepsis, informing whether its increase is associated with the severity of sepsis in patients. Two independent reviewers mapped the information using a previously designed data extraction instrument. The data was analyzed for its relevance and then extracted and synthesized. Results Eleven of 1342 studies were included in the review. The first of them was published in 2017 and the last in 2022. Most of them were developed in the USA, China, and Germany. Studies have reported the actions and bioavailability of nitric oxide and endogenous inhibitors related to its production, and related nitric oxide to the severity of sepsis. Conclusion The physiological production of nitric oxide during sepsis acts as a vascular protector, mainly in the microcirculation but contributes to vascular dysfunction in high concentrations, subverting the regulation of blood pressure, causing deep vasodilation and refractory hypotension, and increasing the severity of sepsis in patients.

Índice leucocitos/eosinófilos como marcador pronóstico del choque séptico / Leukocyte/eosinophil Ratio as a Prognostic Marker of Septic Choque

Introducción: Se ha reconocido mundialmente el choque séptico como causa de una alta incidencia en la mortalidad. La incorporación de nuevos biomarcadores posibilita la obtención de un diagnóstico rápido y preciso. Objetivo: Evaluar la utilidad del índice leucocitos/eosinófilos como marcador pronóstico del choque séptico. Métodos: Se realizó una investigación en dos etapas: la primera descriptiva en la cual se detallaron las características clínicas, epidemiológicas y las variaciones de los estudios de laboratorio y la segunda explicativa de cohorte para estimar el valor predictivo del biomarcador leucocitos/eosinopenia en el choque séptico. Se realizó el recuento de eosinófilos y se obtuvo la media aritmética. Se consideró eosinopenia relativa con valores por debajo de la media de eosinófilos. Resultados: En el estudio se demostró que la leucocitosis fue de (27,4 células*mm3), la disminución del hematocrito (32,2 por ciento) y el descenso del número plaquetario (125,6 célula*mm3) prevalecen en el choque séptico. Además se refleja el descenso de los eosinófilos (18,5 células/mcl), aumento del índice leucocitos/eosinófilos (148,1) y empeoramiento del SOFA (2,8). El aumento del índice leucocitos/eosinófilos se correlaciona con el aumento de la proteína C reactiva y la procalcitonina. Conclusiones: La correlación de la leucocitosis y la eosinopenia mostró la utilidad del índice leucocitos/eosinopenia como factor de predicción del choque séptico(AU)

Introduction: Septic shock has been recognized worldwide as a cause of high incidence of mortality. The incorporation of new biomarkers makes it possible to obtain a rapid and accurate diagnosis. Objective: To evaluate the usefulness of the leukocyte/eosinophil ratio as a prognostic marker of septic shock. Methods: An investigation was carried out in two stages: in the first (the descriptive phase) the clinical and epidemiological characteristics and variations of the laboratory studies were detailed and in the second (the explanatory cohort phase), the predictive value of the leukocytes/eosinopenia biomarker in septic shock was estimated. The eosinophil count was performed and the arithmetic mean was obtained. Relative eosinopenia was considered with eosinophil values below the average. Results: The study showed that leukocytosis was 27.4 cells*mm3, hematocrit decreased in 32.2percent and decreased platelet number (125.6 cells*mm3) prevail in septic shock. In addition, a decrease in eosinophils (18.5 cells/mcl), an increase in the leukocyte/eosinophil ratio (148.1) and worsening of SOFA (2.8) are reflected. The increase in the leukocyte/eosinophil ratio is correlated with the increase in C-reactive protein and procalcitonin. Conclusions: The correlation of leukocytosis and eosinopenia showed the usefulness of the leukocyte/eosinopenia index as a predictor of septic shock(AU)

Síndrome de disfunción orgánica múltiple progresiva en embarazo adolescente: reporte de caso clínico / Progressive multiple organ dysfunction syndrome in adolescent pregnancy: Case report

Introducción El embarazo adolescente es un proceso fisiológico, pero puede evolucionar con parto prematuro, patologías obstétricas o médicas graves, mortalidad o secuelas para madre e hijo/a. Nuestro objetivo es reportar el síndrome de disfunción orgánica múltiple progresiva secundario a pielonefritis y sepsis ocurrido durante el preparto, parto y puerperio de embarazo adolescente y sus secuelas. Caso clínico Adolescente de 14 años, con embarazo de 27 semanas de gestación controlado desde las 8 hasta 25 semanas. Ingresó de urgencia en unidad de alto riesgo obstétrico por signos de parto prematuro, pielonefritis e injuria renal aguda. Se inició tratamiento con cefazolina intravenosa y betametasona para maduración pulmonar, nifedipino oral y sulfato de magnesio para prevención del parto prematuro y protección neuronal fetal, evolucionando con hipotensión sostenida y shock séptico. A las 13 horas después del ingreso, fue trasladada a unidad de paciente crítico donde evolucionó con falla orgánica múltiple persistente y progresiva durante 28 días, afectando sucesivamente los sistemas cardiovascular, hematológico, respiratorio y gastrointestinal. Se trató con drogas vasoactivas, antibióticos, ventilación mecánica invasiva, ultrafiltración, hemodiálisis, drenaje pleural y colecistectomía. A las 24 horas de ingreso a cuidado intensivo, ocurrió el parto prematuro vaginal. La embarazada desarrolló enfermedad renal crónica etapa KDIGO 5 ( V) y se encuentra en espera de trasplante renal. Por su parte, la recién nacida prematura viva presentó asfixia neonatal severa, displasia broncopulmonar y encefalopatía hipóxico-isquémica. Conclusiones El embarazo adolescente complicado es una emergencia sanitaria. El diagnóstico y manejo oportuno de la pielonefritis, shock séptico y disfunción orgánica asociada a la sepsis pueden evitar mortalidad y secuelas permanentes materna y/o neonatal.

Introduction Adolescent pregnancy is a physiological process, but it can evolve with premature delivery, severe obstetric or clinical pathologies, mortality, or sequelae for mother and child. We aim to report the progressive multiple organ dysfunction syndrome secondary to pyelonephritis and sepsis during prepartum, delivery, and puerperium of adolescent pregnancy and its sequelae. Case report A 14-year-old adolescent with a pregnancy of 27 weeks of gestation controlled from 8 to 25 weeks. She was urgently admitted to the high-risk obstetric unit due to signs of preterm labor, pyelonephritis, and acute renal injury. Treatment was started with intravenous cefazolin and betamethasone for lung maturation, oral nifedipine, and magnesium sulfate to prevent preterm labor and fetal neuronal protection, evolving with sustained hypotension and septic shock. At 13 hours after admission, she was transferred to the intensive care unit, where she evolved with persistent and progressive multiple organ failure for 28 days, progressively affecting the cardiovascular, hematologic, respiratory, and gastrointestinal systems. She was treated with vasoactive drugs, antibiotics, invasive mechanical ventilation, ultrafiltration, hemodialysis, pleural drainage, and cholecystectomy. Twenty-four hours after admission to intensive care, preterm vaginal delivery occurred. She developed chronic kidney disease stage KDIGO 5 (Kidney Disease Improving Global Outcomes V) and is awaiting renal transplantation. On the other hand, the preterm newborn presented severe neonatal asphyxia, bronchopulmonary dysplasia, and hypoxic-ischemic encephalopathy. Conclusion Complicated adolescent pregnancy is a health emergency. Avoiding delays in the diagnosis and treatment of pyelonephritis, septic shock and the progressive multiple organ dysfunction syndrome can prevent mortality and permanent sequelae, both maternal and neonatal.

Lack of change in the respiratory quotient during oxygen supply dependence in endotoxemic shock: a subanalysis of an experimental controlled study / Ausência de alteração no quociente respiratório durante a dependência do suprimento de oxigênio no choque endotoxêmico: subanálise de um estudo experimental controlado

ABSTRACT Objective: To evaluate if the reductions in systemic and renal oxygen consumption are associated with the development of evidence of anaerobic metabolism. Methods: This is a subanalysis of a previously published study. In anesthetized and mechanically ventilated sheep, we measured the respiratory quotient by indirect calorimetry and its systemic, renal, and intestinal surrogates (the ratios of the venous-arterial carbon dioxide pressure and content difference to the arterial-venous oxygen content difference. The Endotoxemic Shock Group (n = 12) was measured at baseline, after 60 minutes of endotoxemic shock, and after 60 and 120 minutes of fluid and norepinephrine resuscitation, and the values were compared with those of a Control Group (n = 12) without interventions. Results: Endotoxemic shock decreased systemic and renal oxygen consumption (6.3 [5.6 - 6.6] versus 7.4 [6.3 - 8.5] mL/minute/kg and 3.7 [3.3 - 4.5] versus 5.4 [4.6 - 9.4] mL/minute/100g; p < 0.05 for both). After 120 minutes of resuscitation, systemic oxygen consumption was normalized, but renal oxygen consumption remained decreased (6.3 [5.9 - 8.2] versus 7.1 [6.1 - 8.6] mL/minute/100g; p = not significance and 3.8 [1.9 - 4.8] versus 5.7 [4.5 - 7.1]; p < 0.05). The respiratory quotient and the systemic, renal and intestinal ratios of the venous-arterial carbon dioxide pressure and content difference to the arterial-venous oxygen content difference did not change throughout the experiments. Conclusion: In this experimental model of septic shock, oxygen supply dependence was not associated with increases in the respiratory quotient or its surrogates. Putative explanations for these findings are the absence of anaerobic metabolism or the poor sensitivity of these variables in detecting this condition.

RESUMO Objetivo: Avaliar se as reduções do consumo de oxigênio sistêmico e renal estão associadas ao desenvolvimento de evidências de metabolismo anaeróbico. Métodos: Esta é uma subanálise de estudo já publicado. Em ovinos anestesiados e ventilados mecanicamente, medimos o quociente respiratório por calorimetria indireta e seus substitutos sistêmicos, renais e intestinais (as razões entre a diferença de pressão venoarterial do teor de dióxido de carbono e a diferença arteriovenosa do teor de oxigênio). O Grupo Choque Endotoxêmico (n = 12) foi medido inicialmente, após 60 minutos do choque endotoxêmico e após 60 e 120 minutos da ressuscitação com fluidos e norepinefrina, e os valores foram comparados com os do Grupo Controle (n = 12) sem intervenções. Resultados: O choque endotoxêmico diminuiu o consumo de oxigênio sistêmico e renal (6,3 [5,6 - 6,6] versus 7,4 [6,3 - 8,5] mL/minuto/kg e 3,7 [3,3 - 4,5] versus 5,4 [4,6 - 9,4] mL/minuto/100g; p < 0,05 para ambos). Após 120 minutos de ressuscitação, o consumo sistêmico de oxigênio foi normalizado, mas o consumo renal de oxigênio permaneceu reduzido (6,3 [5,9 - 8,2] versus 7,1 [6,1 - 8,6] mL/minuto/100g; p = NS e 3,8 [1,9 - 4,8] versus 5,7 [4,5 - 7,1]; p < 0,05). O quociente respiratório e as razões sistêmica, renal e intestinal entre a diferença na pressão venoarterial do teor de dióxido de carbono e a diferença arteriovenosa do teor de oxigênio não se alteraram ao longo dos experimentos. Conclusão: Nesse modelo experimental de choque séptico, a dependência do suprimento de oxigênio não foi associada a aumentos no quociente respiratório ou em seus substitutos. As explicações possíveis para esses achados são a ausência de metabolismo anaeróbico ou a baixa sensibilidade dessas variáveis na detecção dessa condição.

Nuevas perspectivas en el estudio y tratamiento de la sepsis

La sepsis es una disfunción orgánica potencialmente mortal debida a una respuesta desregulada del hospedero a la infección. No sólo contribuye con el 20 % de todas las causas de muerte de forma global, sino que los sobrevivientes de esta también pueden experimentar una significativa morbilidad a largo plazo. La sepsis y el shock séptico son emergencias médicas que requieren reconocimiento rápido, administración de antimicrobianos apropiados, soporte hemodinámico cuidadoso y control de la fuente infecciosa. El objetivo de esta revisión fue describir la definición y los criterios diagnósticos, la epidemiología, los factores de riesgo, la patogenia y la conducta inicial ante la sepsis.

Sepsis is a life-threatening organ dysfunction due to a dysregulated host response to infection. It severely impacts global disease burden as it constates 20 % of all causes of death; its survivors may experience long-term morbidity. Sepsis and septic shock are medical emergencies that require rapid identification, administration of appropriate antimicrobials, careful hemodynamic support, and control of the infection source. This review aims to update the definition of sepsis and its diagnostic criteria, epidemiology, risk factors, pathogenesis, and baseline behavior.

La mortalidad relacionada con la infección fue 3,5% (5 pacientes). Conclusiones: El shock séptico se asoció con la bacteriemia persistente y la presencia de focos secundarios de infección.

Background: Available information about risk factors for the development of septic shock is scarce, especially in the pediatric population. Aim: To describe the epidemiological and clinical characteristics of children with community-acquired Staphylococcus aureus bacteremia and to compare the characteristics of children with and without septic shock. Methods: Retrospective cohort study. Inclusion criteria: Children between 30 days and 16 years old, hospitalized in the Juan P. Garrahan Pediatric Hospital between January 2017 and December 2019 for community-acquired infections with S. aureus isolation in blood cultures. Exclusion criteria: History of hospitalization within 3 months prior to admission, living in a closed community, presence of long-term catheter, intraventricular or intraperitoneal devices. Statistical analysis: STATA 16. Results: 142 children were included. 21 children (15%) experienced septic shock. On multivariate analysis, persistent bacteremia (OR 7.15, 95% CI 4.39-23.81, p: 0.001) and secondary focus of infection (OR 6.72, 95% CI 2.02-22.2, p 0.002) were associated with septic shock. The infection-related mortality rate was 3.5% (5 patients). Conclusions: Septic shock was associated with persistent bacteremia and the presence of secondary foci of infection.

Anticoagulación en paciente con síndrome de Lemierre y embolias sépticas pulmonares / Anticoagulation in a patient with Lemierre syndrome and pulmonary septic embolisms

Resumen El síndrome de Lemierre, también denominado trom boflebitis séptica de la vena yugular interna, necrobaci losis o sepsis postanginal es una infección que inicia en el espacio orofaríngeo, se complica con tromboflebitis séptica de la vena yugular interna y metástasis infeccio sas. La rápida progresión a cuadros clínicos graves que comprometen la vida del paciente y su baja frecuencia justifican la divulgación de casos clínicos. Se presenta el caso de una mujer de 27 años de edad, que a las 48 horas de completar el tratamiento con fenoximetilpenicilina por una infección odontógena evolucionó con edema facial y trismus. En la angio-TC de macizo craneofacial se evidenció extenso trombo en la vena yugular interna y en la tomografía computarizada de tórax, embolias sépticas pulmonares. El tratamiento consistió en antibió ticos endovenosos de amplio espectro y anticoagulación de manera precoz.

Abstract Lemierre's syndrome, also called septic thrombo phlebitis of the internal jugular vein, necrobacillosis or postanginal sepsis, is an infection that begins in the oropharyngeal space, is complicated by septic throm bophlebitis of the internal jugular vein and infectious metastases. The rapid progression to serious clinical conditions that compromise the patient's life and its low frequency justify the disclosure of clinical cases. We present the case of a 27-year-old woman who de veloped facial edema and trismus 48 hours after com pleting treatment with phenoxymethylpenicillin for an odontogenic infection. An angio-CT of the craniofacial massif revealed an extensive thrombus in the internal jugular vein and a computed tomography of the chest showed septic pulmonary emboli. Treatment consisted of broad-spectrum intravenous antibiotics and early anticoagulation.

Asociación entre índice de masa corporal y mortalidad en pacientes críticos con choque séptico / Association between body mass index and mortality in critical ill patients with septic shock

INTRODUCCIÓN. La paradoja de la obesidad propone que, en determinadas enfermedades, los enfermos con obesidad tienen menor mortalidad. OBJETIVO. Asociar el índice de masa corporal con la mortalidad a 30 días en adultos con choque séptico. MATERIALES Y MÉTODOS. Estudio observacional, analítico, retrospectivo, multicéntrico. Se analizaron 673 pacientes con choque séptico, ingresados en terapia intensiva de dos hospitales de la ciudad de la ciudad de Quito ­ Ecuador, durante enero 2017 - diciembre 2019. Criterios de inclusión: Mayores a 18 años, choque séptico, registro de peso, talla y condición vital al día 30. Criterios de exclusión: Orden de no reanimación, embarazadas, protocolo de donación de órganos, cuidados paliativos. Las variables se recolectaron a partir de las historias clínicas digitales y físicas de los centros participantes. Las estimaciones de riesgo calculadas se presentaron como OR (Odds Ratio) en el análisis bivariado y OR Adj (OR ajustado) para el análisis multivariado. Un valor de p <0.05 se consideró estadísticamente significativo. Todos los análisis estadísticos se realizaron usando el software estadístico R® (Versión 4.1.2). RESULTADOS. La edad promedio fue de 65 años, índice de masa corporal promedio 25,9 Kg/m2 (+4,9 Kg/m2). El 54,3% tuvo índice de masa corporal > 25 Kg/m2. La mortalidad general fue 49.2%. Sujetos con sobrepeso y obesidad tuvieron menor mortalidad, OR: 0,48 (IC 95%: 0.34, 0.68; p <0.0001) y OR 0.45 (IC 95 %: 0.28, 0.70; p =0.001) respectivamente, con similar tendencia en el análisis multivariado. Los sujetos con peso bajo tuvieron la mayor mortalidad (OR: 2.12. IC 95%: 0.91 - 5.54. p: 0.097). DISCUSIÓN. Los resultados obtenidos apoyan la teoría de paradoja de obesidad, sin embargo, no se realizó evaluación según los niveles de obesidad. CONCLUSIÓN. La mortalidad en choque séptico es menor en sujetos con sobrepeso y obesidad comparada con sujetos con peso normal o bajo peso.

The obesity paradox proposes that, in certain diseases, patients with obesity have lower mortality. OBJECTIVE. To associate body mass index with 30-day mortality in adults with septic shock. MATERIALS AND METHODS. Observational, analytical, retrospective, multicenter, retrospective study. We analyzed 673 patients with septic shock, admitted to intensive care in two hospitals in the city of Quito - Ecuador, during January 2017 - December 2019. Inclusion criteria: older than 18 years, septic shock, weight, height and vital condition at day 30. Exclusion criteria: Do not resuscitate order, pregnant women, organ donation protocol, palliative care. Variables were collected from the digital and physical medical records of the participating centers. Calculated risk estimates were presented as OR (Odds Ratio) in bivariate analysis and OR Adj (adjusted OR) for multivariate analysis. A p value <0.05 was considered statistically significant. All statistical analyses were performed using R® statistical software (Version 4.1.2). RESULTS. The mean age was 65 years, mean body mass index 25.9 kg/m2 (+4.9 kg/m2). Body mass index > 25 kg/m2 was 54.3%. Overall mortality was 49.2%. Overweight and obese subjects had lower mortality, OR: 0.48 (95% CI: 0.34, 0.68; p<0.0001) and OR 0.45 (95 % CI: 0.28, 0.70; p=0.001) respectively, with similar trend in multivariate analysis. Underweight subjects had the highest mortality (OR: 2.12. 95% CI: 0.91 - 5.54. p: 0.097). DISCUSSION. The results obtained support the obesity paradox theory, however, assessment according to obesity levels was not performed. CONCLUSIONS. Mortality in septic shock is lower in overweight and obese subjects compared to normal weight or underweight subjects.

Proceso de enfermería en paciente con choque séptico desde la perspectiva del déficit de autocuidado (caso clínico) / Nursing process in a patient with septic shock from the perspective of self-care deficit

El choque séptico es un estado de hipoperfusión tisular definido como subcategoría de la sepsis en la que las alteraciones circulatorias y del metabolismo celular pueden aumentar considerablemente la mortalidad. A nivel mundial, el choque séptico ocupa el segundo lugar como causa de muerte no coronaria en la Unidad de Cuidados Intensivos (UCI), con una incidencia anual del 10%, y con una mortalidad hospitalaria de 18 a 35%. Objetivo: Describir el abordaje del Proceso de Atención de Enfermería en el paciente con choque séptico y desde la perspectiva del déficit de autocuidado. Metodología: El caso clínico se fundamentó en las etapas del Proceso de Atención de Enfermería (PAE), en la Teoría Enfermera del Déficit de Autocuidado (TEDA) de Dorothea Orem y en herramientas taxonómicas para el abordaje individualizado del plan de cuidados. Resultados: Paciente de 68 años en el servicio de Cuidados Intensivos Adultos, cursa la primera hora del posoperatorio por nefrectomía izquierda secundaria a absceso perirenal, que condiciona a choque séptico. Se abordó el PAE con apoyo del TEDA siendo prioritaria la etiqueta diagnóstica disminución del gasto cardiaco. Conclusiones: La aplicación de las teorías y modelos de enfermería proporcionan un marco de referencia para otorgar cuidados de calidad en los diferentes ámbitos de desempeño, incluyendo unidades de atención de cuidados intensivos. Resulta indispensable usar la metodología del PAE que permite dar evidencia de la profesionalización del cuidado, al usar un lenguaje técnico, con el apoyo de la Teoría de Orem y con las herramientas taxonómicas[AU]

Septic shock is a state of tissue hypoperfusion defined as a subcategory of sepsis in which circulatory and cellular metabolism alterations can considerably increase mortality. Worldwide, septic shock ranks second as a cause of non-coronary death in the Intensive Care Unit (ICU), with an annual incidence of 10%, and a hospital mortality of 18 to 35%. Objective: To describe the approach to the Nursing Care Process in patients with septic shock and from the perspective of self-care deficit. Methodology: The clinical case was based on the stages of the Nursing Care Process (PAE), on the Nursing Theory of Self-Care Deficit (TEDA) by Dorothea Orem and on taxonomic tools for the individualized approach to the care plan. Results: A 68-year-old patient, in the Adult Intensive Care service, undergoes the first postoperative hour due to left nephrectomy secondary to perirenal abscess, which conditions septic shock. The PAE was approached with the support of the TEDA, with a priority being the dignostic label reduction of cardiac output. Conclusions: The application of nursing theories and models provide a frame of reference to provide quality care in different areas of performance, including intensive care units. It is essential to use the PAE methodology that allows to give evidence of the professionalization of care, by using technical language, with the support of Orem's Theory and with taxonomic tools[AU]

Septic complications in patients of traumatic brain injury: An impact on clinical and functional outcome

Background: Septic complications in traumatic brain injury causes short- and long-term cerebral dysregulation by disruption of blood brain barrier, reduced brain perfusion, neuroinflammation and deposition of amyloid. Materials and methods: The present study attempted to observe patients of traumatic brain injury for the development of septic complications during the hospital stay. 89 patients were included in the study with different grades of brain injury (Injury Severity Score (ISS) range, 9-72). The patients were managed according to the trauma protocol and classified into 3 groups based on the severity of trauma (ISS 9-17 (moderate), 18-30 (severe), and >32 (most severe)). The patients were observed for the development of major septic complications during the course of their hospital stay, which impacted on the morbidity and mortality while determining the clinical and functional outcome at the end. Results: Mean age of the study population was 33.5 years. TBI was more common in younger age groups with severe grades of injury, those with multiplicity of head injuries, sepsis with a pulmonary focus, prolonged ICU and in-hospital stay together with high mortality. Septic complications were also more common in cases with higher grades of TBI and more prolonged hospital stay. Patients requiring intubation had a higher risk of developing infectious complications. 69 patients (77.5%) required intubation and mechanical ventilation. Pneumonia was the most common source of sepsis leading to the respiratory failure while the most common cause being aspiration at the time of injury Genitourinary complications were also common leading to urosepsis. Most common organisms isolated were Staphylococcus aureus, Acinetobacter, klebsiella and Pseudomonas. Conclusion: Traumatic brain injury (TBI) when complicated by sepsis and multi organ failure increases the mortality and morbidity with less favorable clinical and functional outcome together with increased duration of ICU and hospital stay.

Children with malignancies and septic shock - an attempt to understand the risk factors

Abstract Objectives: To explain the high mortality of septic shock in children with cancer. Methods: A retrospective cohort from 2016 to 2020, of children aged 0 to 18 years, and septic shock. Results: The authors included 139 patients. Acute lymphocytic leukemia was the most frequent diagnosis (16.5%), and Gram-negative bacteria were the most frequent blood culture isolates (22.3%). There were 57 deaths in ICU (41%), 10 in the first 24 hours of shock (early death). A LASSO model with variables: neutropenia (coefficient 0.215), respiratory (0.81), hematological (1.41), and neurological (0.72) dysfunctions, age (-0.002) and solid tumor recurrence (0.34) generated AUC = 0.79 for the early death outcome. Survivors had significant differences in the PRISM-IV score (mean ± SD 10.9 ± 6.2 in the survivors, 14.1 ± 6.5 in the deceased, p = 0.004), and in the mean number of organ dysfunctions (3.2 ± 1.1 in the survivors, 3.8 ± 6.5 in the deceased, p < 0.001). A positive fluid balance in the first 24 hours of sepsis between 2% and 6% of body weight showed a reduction effect on the probability of death in ICU (hazard ratio 0.47, 95% CI 0.24-0.92, p = 0.027). The recurrence of any cancer was a predictor of in-hospital death, regardless of severity. Conclusions: Recurrence of any cancer is an important risk of sepsis-related death. A positive fluid balance between 20 and 60 mL/kg or 2% and 6% of body weight in the first 24 hours after the onset of sepsis is related to lower mortality.

A rare diagnosis has no certainty, but still they occur: A case report

Pain and swelling are among the most frequently encountered complaints in an orthopedics outpatient department (OPD) relatively less common in a pediatric OPD. A high level of suspicion is required to diagnose bone diseases. Common conditions such as rickets, septic arthritis, and tuberculosis must be ruled out. Treatment such as antibiotics, anti-inflammatory drugs, or steroids may mask an underlying serious condition in which if left untreated can cause significant morbidity and mortality to the person. Here, we discuss a case of a young infant 11 months of age who had symptoms suggestive of septic arthritis and was later found to have Brodie’s abscess which is a type of subacute osteomyelitis on further evaluation which is usually mistaken as a tumor. This age at presentation is rare.

Advances in Shock Management and Fluid Resuscitation in Children

Shock in children is associated with signifcant mortality and morbidity, particularly in resource-limited settings. The principles of management include early recognition, fuid resuscitation, appropriate inotropes, antibiotic therapy in sepsis, supportive therapy for organ dysfunction, and regular hemodynamic monitoring. During the past decade, each step has undergone several changes and evolved as evidence that has been translated into recommendations and practice. There is a paradigm shift from protocolized-based care to personalized management, from liberal strategies to restrictive strategies in terms of fuids, blood transfusion, ventilation, and antibiotics, and from clinical monitoring to multimodal monitoring using bedside technologies. However, uncertainties are still prevailing in terms of the volume of fuids, use of steroids, and use of extracorporeal and newer therapies while managing shock. These changes have been summarized along with evidence in this article with the aim of adopting an evidence-based approach while managing children with shock.

Infección osteoarticular multifocal en un recién nacido / Multifocal osteoarticular infection in a neonate / Infecção osteoarticular multi-focal num recém-nascido

Tanto la osteomielitis como la osteoartritis séptica en el período neonatal son patologías infrecuentes. La afectación ósea de la columna cervical es aún más rara, siendo excepcional en neonatos. Son patologías graves, con elevada morbimortalidad, donde el diagnóstico y tratamiento precoz agresivo son de suma importancia para el pronóstico vital y funcional. Presentamos el caso de un neonato que presentó una sepsis a S. Aureus multirresistente, asociada a una osteomielitis de la primera vértebra cervical y a una osteoartritis séptica de la cadera izquierda. Fue tratado precozmente de forma quirúrgica y con antibioticoterapia, presentando una buena evolución.

Both osteomyelitis and septic osteoarthritis in the neonatal period are infrequent pathologies. Bone involvement of the cervical spine is even rarer, being exceptional in neonates. These are serious pathologies, with high morbimortality, where early diagnosis and aggressive treatment are of utmost importance for the vital and functional prognosis. We present the case of a neonate who presented with sepsis due to multidrug-resistant S. Aureus, associated with osteomyelitis of the first cervical vertebra and septic osteoarthritis of the left hip. He was treated early surgically and with antibiotic therapy, presenting a good evolution

Tanto a osteomielite como a osteoartrose séptica no período neonatal são patologias raras. O envolvimento ósseo da coluna cervical é ainda mais raro, sendo excepcional nos recém-nascidos. Estas são patologias graves, com elevada morbimortalidade, onde o diagnóstico precoce e o tratamento agressivo são da maior importância para o prognóstico vital e funcional. Apresentamos o caso de um recém-nascido que apresentou sepse devido a S. Aureus multirresistente, associado a osteomielite da primeira vértebra cervical e osteoartrose séptica da anca esquerda. Foi tratado precocemente cirurgicamente e com terapia antibiótica, com uma boa evolução.

Efficacy of ultrasound-guided percutaneous transhepatic biliary drainage for acute obstructive suppurative cholangitis combined with septic shock

Abstract Objectives This study aimed to investigate the efficacy of ultrasound-guided Percutaneous Transhepatic Biliary Drainage (PTCD) for the treatment of Acute Obstructive Suppurative Cholangitis (AOSC) combined with septic shock due to choledocholithiasis, and its effect on inflammatory factors. Methods Clinical data of 86 patients with AOSC and septic shock admitted to our hospital between January 2019 and May 2021 were retrospectively analyzed and grouped according to different treatment methods. Among them, 43 patients who underwent Endoscopic Retrograde Cholangiopancreatography (ERCP) and Endoscopic Nasobiliary Drainage (ENBD) were included in the Control Group (CNG), and 43 patients who underwent ultrasound-guided PTCD were included in the Study Group (SG). Results The total effective rate in the SG (88.37%) was higher than that in the CNG (69.77%) (p <0.05); after surgery, the serum inflammatory factors PCT, IL-6, TNF-α, CRP levels, liver function indicators such as TBIL, DBIL, AST, ALT levels, and stress response indicators including NPY, PGE2, 5-HT levels were reduced, and were lower in the SG than in the CNG (p <0.05); postoperatively, CD3+, CD4+, and CD4+/CD8+ levels in the CNG were significantly lower than those before surgery (p <0.05); Postoperatively, CD3+, CD4+, and CD4+/CD8+ levels in the SG were significantly higher than those in the CNG (p <0.05); and the complication rate in the SG (6.98%) was lower than that in the CNG (25.58%) (p <0.05). Conclusions Ultrasound-guided PTCD for AOSC combined with septic shock can facilitate the recovery of liver and immune functions with a low complication rate.

Serum galectin-3 levels predict poor prognosis in sepsis and septic shock patients

SUMMARY OBJECTIVE: Sepsis and septic shock are clinical conditions with high mortality and an ever-increasing prevalence, and early diagnosis is of great importance in treating these diseases. Increase in serum Galectin-3 protein in septic patients is associated with increased inflammation, which in turn is associated with mortality. This study aimed to investigate the diagnostic importance of serum Galectin-3 levels and its relationship with in-hospital mortality in sepsis and septic shock patients. METHODS: This prospective cohort study included 44 sepsis and 44 septic shock patients. Sequential Organ Failure Assessment score and Acute Physiology and Chronic Health Evaluation 2 score were calculated. In addition, routine clinical and laboratory parameters along with serum Galectin-3 were evaluated. RESULTS: Serum Galectin-3 levels were significantly higher in the septic shock group [4.1 (0.1-10.2) vs. 6.0 (0.1-11.3) ng/mL, respectively; p=0.01]. Moreover, patients with a Galectin-3 level <6.94 ng/mL were associated with longer survival [31.4 vs. 23.1 days; hazards ratio, 1.85; 1.03-3.34, p=0.03]. More importantly, the need for mechanical ventilation, the duration of mechanical ventilation, and serum Galectin-3 levels were independent prognostic factors and predicted poor in-hospital survival in both sepsis and septic shock patients. CONCLUSION: These findings suggest that Galectin-3 levels are higher in septic shock patients and predict mortality. In addition, high serum Galectin-3 levels, together with mechanical ventilation requirement and mechanical ventilation duration, are closely associated with poor in-hospital survival. Therefore, Galectin-3 may be a valuable diagnostic and prognostic biomarker in these patients.

Cytokine hemoadsorption with CytoSorb® in patients with sepsis: a systematic review and meta-analysis / Hemoadsorção de citocinas com CytoSorb® em pacientes com sepse: revisão sistemática e metanálise

ABSTRACT Objective: To analyze the effect of CytoSorb® on mortality, interleukin levels, vasopressor use and adverse events in patients with sepsis. Methods: We searched MEDLINE®, Embase and the Cochrane Library for randomized controlled trials and cohort studies that reported the use of CytoSorb® among septic patients. The primary outcome was mortality, and secondary outcomes included the use of vasopressors, levels of inflammatory markers, predicted versus observed mortality, length of stay in the intensive care unit, and adverse events. Results: We included 6 studies enrolling 413 patients, and assessment for risk of bias indicated variations in study quality from high to moderate. The overall mortality rate was 45%, and no significant effect on mortality was found at 28 - 30 days (RR 0.98 [0.12 - 8.25] for the randomized clinical trial and RR 0.74 [0.49 - 1.13] for cohort studies). We did not perform a metanalysis for other outcomes due to the small number of studies found or the lack of data. Conclusion: Our study found very low certainty evidence, due to imprecision, risk of bias, and heterogeneity, thereby showing no benefit of CytoSorb® use in terms of mortality at 28 - 30 days. We cannot recommend the use of CytoSorb® in septic or septic shock patients outside clinical trials. Further high-quality randomized trials with a common intervention arm are needed to evaluate the influence of CytoSorb® in this population. PROSPERO register: CRD42021262219

RESUMO Objetivo: Analisar o efeito de CytoSorb® na mortalidade, nos níveis de interleucina, no uso de vasopressores e nos eventos adversos em pacientes com sepse. Métodos: Pesquisamos o MEDLINE®, o Embase e a Biblioteca Cochrane em busca de ensaios clínicos randomizados e estudos de coorte que relatassem o uso de CytoSorb® em pacientes com sepse. O desfecho primário foi a mortalidade, e os desfechos secundários incluíram uso de vasopressores, níveis de marcadores inflamatórios, mortalidade prevista versus observada, tempo de internação na unidade de terapia intensiva e eventos adversos. Resultados: Incluímos 6 estudos com 413 pacientes, e a avaliação do risco de viés indicou variações na qualidade do estudo de alta a moderada. A taxa de mortalidade geral foi de 45%, e não foi encontrado efeito significativo na mortalidade entre 28 e 30 dias (risco relativo de 0,98 [0,12 - 8,25] para o ensaio clínico randomizado e de 0,74 [0,49 - 1,13] para estudos de coorte). Não realizamos metanálise para outros desfechos, devido ao pequeno número de estudos encontrados ou à carência de dados. Conclusão: Nosso estudo encontrou evidências de certeza muito baixa, devido à imprecisão, ao risco de viés e à heterogeneidade, demonstrando nenhum benefício no uso de CytoSorb® em termos de mortalidade em 28 a 30 dias. Não podemos recomendar o uso de CytoSorb® em pacientes com sepse ou choque séptico fora dos estudos clínicos. São necessários mais estudos randomizados de alta qualidade com um braço de intervenção comum para avaliar a influência de CytoSorb® nessa população. Registro PROSPERO: CRD42021262219

Sepsis and septic shock: epidemiology, clinical parameters, and prognostic factors in a brazilian intensive care unit / Sepse e choque séptico: epidemiologia, parâmetros clínicos e fatores prognósticos em uma unidade de terapia intensiva brasileira / Sepsis y shock séptico: epidemiología, parámetros clínicos y factores pronósticos en una unidad de cuidados intensivos brasileña

Sepsis is an organ dysfunction caused by a dysregulated host response to infection and is associated with high morbidity and mortality. The identification of prognostic markers in this syndrome has been a strategy to increase treatment efficacy. The objectives of this study were: 1) to describe the epidemiological and microbiological profile of septic patients and 2) to investigate the association between laboratory/clinical parameters and mortality rate, identifying prognostic markers. Using a prospective observational protocol, epidemiological, clinical and laboratory data were collected from adult patients with sepsis or septic shock admitted to a Brazilian Intensive Care Unit. During the study period, 120 patients were diagnosed with sepsis and 71.67% (n = 86) were included in the protocol. The overall mortality was 69.76% and chronic diseases were identified in 79.07% of cases. The mortality rates for sepsis and septic shock were 51.06% and 92.31%, respectively. SOFA scores on the first, third, and seventh days of hospitalization gradually increased for patients who had clinical worsening. Hyperlactatemia and hyperglycemia were identified in 45.9% and 27% of patients, respectively, and were associated with mortality. INR values greater than 1.5 or thrombocytopenia were related to 92.9% and 88.6% mortality, respectively. In the study, gender, age, ICU stay, site of infection and microbiological agent were not associated with the risk of death. However, the presence of comorbidities, high SOFA scores, three or more organ dysfunctions, and sepsis severity correlated directly with mortality rate.

A sepse é uma disfunção orgânica causada por uma resposta desregulada do hospedeiro à infecção e está associada a alta morbidade e mortalidade. A identificação de marcadores prognósticos nessa síndrome tem sido uma estratégia para aumentar a eficácia do tratamento. Os objetivos deste estudo foram: 1) descrever o perfil epidemiológico e microbiológico de pacientes sépticos e 2) investigar a associação entre parâmetros laboratoriais/clínicos e a taxa de mortalidade, identificando marcadores prognósticos. Por meio de um protocolo observacional prospectivo foram coletados dados epidemiológicos, clínicos e laboratoriais de pacientes adultos com sepse ou choque séptico internados em uma Unidade de Terapia Intensiva brasileira. No período do estudo, 120 pacientes foram diagnosticados com sepse e 71,67% (n = 86) foram incluídos no protocolo. A mortalidade geral foi de 69,76% e doenças crônicas foram identificadas em 79,07% dos casos. As taxas de mortalidade por sepse e choque séptico foram de 51,06% e 92,31%, respectivamente. Os escores SOFA no primeiro, terceiro e sétimo dias de internação aumentaram gradativamente para os pacientes que apresentaram piora clínica. Hiperlactatemia e hiperglicemia foram identificadas em 45,9% e 27% dos pacientes, respectivamente, tendo sido associadas à mortalidade. Valores de INR maiores que 1,5 ou trombocitopenia foram relacionados a 92,9% e 88,6% de mortalidade, respectivamente. No estudo, sexo, idade, permanência na UTI, local da infecção e agente microbiológico não se associaram ao risco de óbito. No entanto, a presença de comorbidades, altos escores SOFA, três ou mais disfunções orgânicas e a gravidade da sepse correlacionaram-se diretamente com a taxa de mortalidade.
