Is it in their eyes? Correlation between microorganisms isolated from bronchial aspirates and conjunctival swabs in a Pediatric Intensive Care Unit / ¿Está en sus ojos? Correlación entre microorganismos aislados de aspirados bronquiales e hisopos conjuntivales en una Unidad de Cuidados Intensivos Pediátricos

Objectives. Our observational, retrospective study aimed to determine the correlation between bacteria isolated from bronchial aspirates of pediatric ICU patients (PICU) with respiratory infections and those obtained from conjunctival swabs of the same patients exhibiting clinical conjunctivitis. Material and methods. Throughout the period from 2015 to 2022, we reviewed all clinically significant bronchial aspirates (≥105 CFU/mL) and positive conjunctival swabs obtained from PICU patients. These records were retrieved from the microbiology database, cross-referencing the data to identify patients who tested positive for both during the same clinical episode. Results. The median age of the patients was 5 months (interquartile range: 1-7). Among the cohort, twenty-one patients exhibited positivity in both bronchial aspirate and conjunctival swab samples, showcasing a microbial match in 85.71% of cases (18 out of 21). The most frequently isolated microorganisms were Haemophilus influenzae (55.6%), followed by Pseudomonas aeruginosa (14.3%), Klebsiella aerogenes (9.5%), and Escherichia coli, Stenotrophomonas maltophilia, and Enterobacter cloacae, each accounting for 4.8% of the isolates. Conclusions. Our study demonstrates a strong concordance between the isolated microorganisms from both samples in patients presenting clear symptoms of clinical conjunctivitis. These findings provide a basis for future prospective studies that may leverage conjunctival swabs as a predictive tool for identifying microorganisms involved in respiratory infections. (AU)

Objetivos. Nuestro estudio observacional y retrospectivo tuvo como objetivo determinar la correlación entre las bacterias aisladas de aspirados bronquiales de pacientes de UCI pediátrica (UCIP) con infecciones respiratorias y las obtenidas de hisopos conjuntivales de los mismos pacientes que presentaban conjuntivitis clínica. Material y métodos. A lo largo del periodo comprendido entre 2015 y 2022, se revisaron todos los aspirados bronquiales clínicamente significativos (≥105 UFC/mL) y los hisopos conjuntivalespositivos obtenidos de pacientes de UCIP. Estos registros se recuperaron de la base de datos de microbiología, cruzando los datos para identificar a los pacientes que dieron positivo en ambos durante el mismo episodio clínico. Resultados. La mediana de edad de los pacientes fue de 5 meses (rango intercuartílico: 1-7). Entre la cohorte, veintiún pacientes presentaron positividad tanto en las muestras de aspirado bronquial como en las de hisopo conjuntival, mostrando una coincidencia microbiana en el 85,71% de los casos (18 de 21). Los microorganismos más frecuentemente aislados fueron Haemophilus influenzae (55,6%), seguido de Pseudomonas aeruginosa (14,3%), Klebsiella aerogenes (9,5%) y Escherichia coli, Stenotrophomonas maltophiliay Enterobacter cloacae, cada uno de los cuales representó el 4,8% de los aislamientos. Conclusiones. Nuestro estudio demuestra una fuerte concordancia entre los microorganismos aislados de ambas muestras en pacientes que presentan síntomas claros de conjuntivitis clínica. Estos hallazgos proporcionan una base para futuros estudios prospectivos que podrían aprovechar los hisopos conjuntivales como herramienta predictiva para identificar microorganismos implicados en infecciones respiratorias.

Coinfecciones y sobreinfecciones en pacientes con diagnóstico de COVID-19 ingresados en terapia del Hospital Hermanos Ameijeiras / Behavior of coinfections and superinfections in COVID-19 patients admitted to the intensive care unit at Hermanos Ameijeiras Hospital

Introducción: La enfermedad COVID-19 se ha asociado a un incremento de los ingresos en terapia intensiva. La probabilidad de muerte se eleva con las coinfecciones y sobreinfecciones. Objetivo: Determinar la presencia de coinfecciones y aparición de sobreinfecciones en pacientes con COVID-19 ingresados en terapia, los factores asociados a esta y su relación con la mortalidad. Métodos: Se realizó un estudio analítico transversal donde se estudió a 79 pacientes positivos al virus SARS-CoV-2 en 8 meses en el servicio de la terapia del Hospital Hermanos Ameijeiras. Se estudiaron variables demográficas, clínicas y de manejo en terapia. Las variables categóricas se expresaron en frecuencias absoluta y relativa. Las variables cuantitativas se describieron según la mediana y sus rangos intercuartílicos. Se empleó la prueba de rangos de Wilcoxon, ji al cuadrado de Pearson y el modelo de regresión logística multinomial para determinar las variables predictoras independientes de la sobreinfección. Resultados: Presentaron sobreinfección 34 pacientes (43 %). Hubo una mortalidad del 43 % con 34 pacientes, de estos se sobreinfectaron 18 pacientes. Se obtuvo una asociación causal entre la sobreinfección y la estadía hospitalaria (OR: 1,56; IC: 95 %: 1,26-2,08; p < 0,001), el uso de ventilación mecánica invasiva (OR: 3,28; IC: 95 %: 1,30-8,73; p = 0,014) y el tiempo de empleada esta (OR: 1,37; IC: 95 %: 1,15-1,71; p< 0,001). Conclusiones: No se encontró asociación estadística entre la mortalidad y la sobreinfección en los pacientes estudiados. Hubo poca representación de coinfecciones. La estadía en terapia, el uso de ventilación mecánica invasiva y el tiempo de empleada esta fueron variables predictoras en la aparición de sobreinfección.

Introduction: COVID-19 is associated with an increase in the number of admissions to the intensive care units. The likelihood of fatality cases increases with coinfections and superinfections. Objective: To determine the presence of coinfections and the occurrence of superinfections in COVID-19 patients admitted to the intensive care unit, its associated factors and its relationship with mortality. Methods: It was conducted a cross-sectional analytic study in 79 patients with positive SARS-CoV-2 tests during eight months in the intensive care units at Hermanos Ameijeiras Hospital. Demographic, clinical and management variable were studied. Categorical variables were expressed in terms of absolute and relative frequencies. Quantitative variables were described based on their median and their interquartile ranges. The Wilcoxon rank test, Pearson's chi-squared test and the multinomial logistic regression model were used to determine the independent predictor variables of superinfection. Results: Superinfection occurred in 34 patients (43%). The mortality rate was 43% with 34 patients, of which 18 had superinfections. A causal association was established between superinfection and hospital stay (OR: 1.56; CI: 95%: 1.26-2.08; p < 0.001), the use of invasive mechanical ventilation (OR: 3.28; CI: 95%: 1.30-8.73; p = 0.014) and the time this procedure was used (OR: 1.37; CI: 95%: 1.15-1.71; p < 0.001). Conclusions: No statistical association was found between mortality and superinfection in the patients under study. There was low presence of coinfections. The stay in the intensive care unit, the use of invasive mechanical ventilation and the time this procedure was used were predictive variables for the occurrence of superinfection.

Cavitaciones pulmonares, complicación tardía de la COVID-19 / Pulmonary cavitations, late complication of COVID-19

La aparición de complicaciones graves, como el neumotórax o las cavitaciones pulmonares, en pacientes con infecciones recientes por el SARS-CoV-2 aumenta la morbi-mortalidad, y supone un reto diseñar la estrategia terapéutica más adecuada que permita mejorar su pronóstico. Las cavitaciones pulmonares se suelen asociar a complicaciones secundarias como la hemoptisis y el neumotórax, y confieren mal pronóstico. Se presenta el caso de dos pacientes con enfermedad COVID-19 confirmada por PCR nasofaríngea y que, tras evolución inicialmente satisfactoria, reingresaron con afectación pulmonar compatible con cavitaciones pulmonares y con insuficiencia respiratoria. Las lesiones cavitadas pulmonares en pacientes que hayan sufrido COVID-19 deben identificarse de forma precoz y realizar las determinaciones y cultivos necesarios para descartar sobreinfecciones añadidas que puedan empeorar el pronóstico.(AU)

Patients who have recently suffered from SARS-CoV-2 infections may suffer serious complications, such as pneumothorax or pulmonary cavitations that increase morbi-mortality and imply a challenge for the design of the most appropriate therapeutic strategy to improve their prognosis. Pulmonary cavities are usually associated with secondary complications such as hemoptysis and pneumothorax, and so offer a poor prognosis. We present the case of two patients with COVID-19 disease confirmed by nasopharyngeal PCR who showed satisfactory evolution before readmission with pulmonary involvement compatible with pulmonary cavitation and respiratory failure. Cavitated lesions in the lungs of patients who recently suffered COVID-19 must be identified early in order to discard additional superinfections that may worsen the prognosis.(AU)

Comparación de datos demográficos, clínicos y microbiológicos en función del ingreso en UCI e identificación de los factores predictores de mortalidad mediante regresión logística multivariante.ResultadosDe 712 pacientes con COVID-19, 113 (16%) presentaron coinfección/ sobreinfección bacteriana/fúngica. Mediana de edad 73 años (RIQ 57-89), 59% de ellos hombres. Perfil del paciente de UCI (44%): hombre con neumonía por SARS-CoV-2, leucocitosis, interleucina-6 elevada, con interferón β-1b y tocilizumab y sobreinfección (p < 0,05). El 5% (39/712) de los pacientes presentaron una coinfección. Streptococcus pneumoniae (6) y Staphylococcus aureus (6) fueron los principales patógenos de las coinfecciones respiratorias (18). El 11% (80/712) se sobreinfectaron. Las infecciones más frecuentes fueron las urinarias (53) e IRs (39). Acinetobacter baumannii multirresistente fue el principal agente de la IR y la bacteriemia. Un brote por A. baumannii contribuyó a este resultado. Tres pacientes se diagnosticaron como probable aspergilosis pulmonar. La mortalidad fue superior en los pacientes de UCI (50 vs. 29%; p = 0,028).

Supervivencia en pacientes con neumonía grave por SARS-CoV-2 con sobreinfección en una Unidad de Cuidados Intensivos / Survival in patients with severe SARS-CoV-2 pneumonia with superinfection in an Intensive Care Unit / Sobrevivência em pacientes com pneumonia grave por SARS-CoV-2 com superinfecção em uma Unidade de Terapia Intensiva

Resumen: Introducción: La sobreinfección en pacientes con síndrome respiratorio agudo severo por coronavirus 2 (SARS-CoV-2) no está completamente entendida y requiere ser atendida para evitar el uso excesivo de antibióticos. Material y métodos: Estudio observacional, retrospectivo, longitudinal, comparativo, en pacientes con neumonía grave por SARS-CoV-2. Se calculó la probabilidad de supervivencia individual acumulada a lo largo de 90 días con el método de Kaplan Meier, en grupos con sobreinfección o ausencia de desarrollo de microorganismos aislados mediante cultivos de secreción bronquial, hemocultivos central y periférico, y urocultivos. Resultados: Se reclutaron 82 pacientes, 21 (25.6%) presentaron crecimiento bacteriano o fúngico en cultivos de secreción bronquial, ocho (9.7%) presentaron crecimiento bacteriano en hemocultivos periféricos, cinco (6%) tuvieron desarrollo bacteriano en hemocultivos centrales, y 16 (19.5%) presentaron crecimiento bacteriano o fúngico en urocultivos. La supervivencia en estos pacientes fue menor, sin ser significativa, con respecto a quienes no tuvieron sobreinfección (p = 0.352, 0.280, 0.119, 0.302 respectivamente). Conclusión: La sobreinfección en los pacientes con neumonía grave por SARS-CoV-2 no demostró ser un factor asociado a menor supervivencia y aunque la prevalencia de sobreinfección no es despreciable, no hay evidencia suficiente para respaldar el uso generalizado de antibióticos empíricos.

Abstract: Introduction: Superinfection in patients with severe acute respiratory syndrome by coronavirus 2 (SARS-CoV-2) is not completely understood and requires attention to avoid the excessive use of antibiotics. Material and methods: Observational, retrospective, longitudinal, comparative study in patients with severe SARS-CoV-2 pneumonia. The accumulated probability of individual survival over 90 days was calculated with the Kaplan Meier m ethod, in groups with superinfection or absence of development of isolated microorganisms using cultures of bronchial secretion, central and peripheral blood cultures, and urine cultures. Results: Eighty-two patients were recruited, 21 (25.6%) presented bacterial or fungal growth in cultures of bronchial secretion, eight (9.7%) presented bacterial growth in peripheral blood cultures, five (6%) had bacterial development in central blood cultures, and 16 (19.5%) presented bacterial or fungal growth in urine cultures. Survival in these patients was lower, without being significant, with respect to those who did not have superinfection, (p = 0.352, 0.280, 0.119, 0.302 respectively). Conclusion: Superinfection in patients with severe SARS-CoV-2 pneumonia has not been shown to be a factor associated with lower survival, and although the prevalence of superinfection is not negligible, there is insufficient evidence to support the generalized use of empirical antibiotics.

Resumo: Introdução: A superinfecção em pacientes com síndrome respiratória aguda grave pelo coronavírus 2 (SARS-CoV-2) não é totalmente compreendida e requer atenção para evitar o uso excessivo de antibióticos. Material e métodos: Estudo observacional, retrospectivo, longitudinal e comparativo em pacientes com pneumonia grave por SARS-CoV-2. A probabilidade acumulada de sobrevida individual em 90 dias foi calculada pelo método de Kaplan Meier, nos grupos com superinfecção ou ausência de desenvolvimento de microrganismos isolados por meio de cultura de secreção brônquica, hemocultura central e periférica e cultura de urina. Resultados: Foram recrutados 82 pacientes, 21 (25.6%) apresentaram crescimento bacteriano ou fúngico em culturas de secreção brônquica, 8 (9.7%) apresentaram crescimento bacteriano em hemoculturas periféricas, 5 (6%) apresentaram desenvolvimento bacteriano em hemoculturas centrais, e 16 (19.5%) apresentaram crescimento bacteriano ou fúngico nas culturas de urina. A sobrevida nesses pacientes foi menor, sem ser significativa, em comparação com aqueles que não tiveram superinfecção, (p = 0.352, 0.280, 0.119, 0.302 respectivamente). Conclusão: A superinfecção em pacientes com pneumonia grave por SARS-CoV-2 não demonstrou ser um fator associado a menor sobrevida e, embora a prevalência de superinfecção não seja desprezível, não há evidências suficientes para apoiar o uso generalizado de antibióticos empíricos.

Uso racional de antimicrobianos en tiempos de COVID-19 en Perú: rol de los programas de optimización del uso de antimicrobianos e intervenciones desde el punto de vista de control de infecciones

La resistencia antimicrobiana (RAM) es una pandemia adicional de lenta evolución que precede a la pandemia de COVID-19 y continuará cuando esta termine. Sin embargo, en países como Perú, donde existe un alto consumo y prescripción inadecuada de antimicrobianos, puede pasar desapercibida y se puede esperar, en el futuro, un escenario más desafiante. Los programas de optimización de uso de antimicrobianos (PROA) son equipos multidisciplinarios de profesionales que tienen como objetivo retardar la aparición de organismos multirresistentes a través de estrategias como la auditoría de prescripciones o la creación de algoritmos de tratamiento antimicrobiano basados en las tasas locales de RAM. La dificultad en el diagnóstico oportuno de coinfecciones o superinfecciones en el curso clínico y progresión de la COVID-19 predisponen al uso inadecuado de antimicrobianos, lo que obliga a los PROA a adaptar sus estrategias en este panorama cambiante. En Latinoamérica, los PROA no solo tienen que fomentar el cambio de comportamiento en los prescriptores de antimicrobianos, sino también luchar contra la epidemia de información falsa (infodemia) y las campañas de desinformación sobre la COVID-19. Además, la pobre cultura local de prevención y control de infecciones obliga a revisar estrategias para mitigar el impacto posterior en la RAM.

Antimicrobial resistance (AMR) is an additional slow-evolving pandemic that precedes the COVID-19 pandemic and will continue when it ends. However, in countries like Peru, where high consumption and inadequate prescription of antimicrobials occur, AMR may go unnoticed and a more challenging future scenario can be expected. Antimicrobial stewardship programs (ASPs) consist of multidisciplinary teams of professionals that aim to slow down the emergence of multidrug-resistant organisms through strategies such as prescription auditing or creation of antimicrobial treatment guidelines based on local AMR rates. The difficulty in the timely diagnosis of co-infections or superinfections in the clinical course and progression of COVID-19 leads to inappropriate use of antimicrobials, forcing ASPs to adapt their strategies in this changing scenario. In Latin America, ASPs not only have to promote behavior change in antimicrobial prescribers but also fight the epidemic of false information (infodemic) and disinformation campaigns on COVID-19. Furthermore, poor-quality infection prevention and control principles require evaluating strategies to mitigate the subsequent impact on AMR.

Ectima gangrenoso en pediatría / Ecthyma gangrenosum in pediatrics

Resumen El ectima gangrenoso es una infección poco frecuente de la piel, conocida con una característica lesión causada principalmente por la Pseudomoma aeruginosa, pero que también se puede presentar por otro tipo de bacterias del tipo Staphylococcus aureus o el Streptococcus beta hemolítico del grupo A ( S. beta hemolítico del grupo A), entre otros. Esta entidad se asocia frecuentemente con inmunodeficiencias primarias y secundarias. Las lesiones, clínicamente, se presentan como máculas eritematovioláceas, descamativas que rápidamente evolucionan a papulovesículas, ampollas hemorrágicas y costrosas que dejan unas úlceras profundas en sacabocado con fondo necrótico. La mortalidad es alta, entre 40 y 75% de los individuos inmunológicamente comprometidos. Se describe el caso de una niña de 5 años que inicialmente presentó varicela y luego una sobreinfección por S. aureus ocasionando un cuadro clínico de un ectima gangrenoso; al diagnóstico se llega por la clínica, cultivos y biopsias de piel. Se realizó manejo con aciclovir, clindamicina y cefepime endovenoso, con buena y rápida respuesta de la paciente.

Abstract Ecthyma gangrenosum (EG) is a rare infection of the skin, known as a characteristic lesion caused by Pseudomoma aeruginosa , but also can occur from other types of bacteria like Staphylococcus aureus or beta hemolytic group, among others. This condition is often associated with primary and secondary immunodeficiencies. The lesions present clinically as scaly, erythematous violacious macules that rapidly evolve into papule-vesicles, bleeding and crusty blisters leaving a deep punch ulcer with a necrotic base. Mortality is high, between 40% and 75% of immunologically compromised individuals. We describe the case of a girl of 5 years of age who initially presented chickenpox and then superinfection with Staphylococcus aureus, causing a clinical picture of EG. The diagnosis was reached based on symptoms, cultures and skin biopsies. Management was achieved with acyclovir, intravenous clindamycin and cefepime, with a good and quick response by the patient.
