ABSTRACT
Introducción. El dengue es un problema de salud pública a nivel mundial. Confinado en sus orígenes a las zonas tropicales y subtropicales, en la actualidad se presenta en otras regiones como Argentina. Desde el año 2008 se presenta con brotes epidémicos en la Ciudad Autónoma de Buenos Aires, con escasos reportes en niños. Objetivo. Analizar y comparar las características clínicas, epidemiológicas, de laboratorio y evolutivas de los dos últimos brotes de dengue fuera del área endémica. Población y métodos. Estudio de series temporales. Se incluyeron pacientes menores de 18 años con dengue probable o confirmado, evaluados en un hospital pediátrico de la Ciudad de Buenos Aires durante los períodos 2015-2016 y 2019-2020. Resultados. Se incluyeron 239 pacientes, 29 (12 %) con antecedente de viaje. La mediana de edad fue de 132 meses (rango intercuartílico: 102-156). Todos tuvieron fiebre. Otros síntomas fueron: cefalea en 170 (71 %), mialgias en 129 (54 %) y exantema en 122 (51 %). Cuarenta pacientes (17 %) tenían comorbilidades. Presentaron signos de alarma 79 pacientes (33 %) y 14 (6 %) tenían dengue grave. Requirieron internación 115 pacientes (45 %) y ninguno falleció. El serotipo DENV-1 fue el más frecuente. El antecedente de viaje y la necesidad de internación predominaron en el primer período; el dengue grave y la infección previa, en el segundo. Conclusiones. Ningún paciente falleció de dengue en los períodos estudiados. Se observaron diferencias estadísticamente significativas en la frecuencia de internación; el antecedente de viaje fue más frecuente en el período 2015-2016 y el dengue grave, en el 2019-2020.
Introduction. Dengue is a public health problem worldwide. It was originally confined to tropical and subtropical areas, but it is now present in other regions, such as Argentina. Epidemic outbreaks have been observed in the City of Buenos Aires since 2008, with few reports in children. Objective. To analyze and compare the clinical, epidemiological, laboratory, and evolutionary characteristics of the latest 2 dengue outbreaks outside the endemic area. Population and methods. Time-series study. Patients under 18 years of age with probable or confirmed dengue and evaluated in a children's hospital of the City of Buenos Aires during the periods 2015-2016 and 2019-2020 were included. Results. A total of 239 patients were included; 29 (12%) had a history of travel. Their median age was 132 months (interquartile range: 102156). All had a fever. Other symptoms included headache in 170 (71%), myalgia in 129 (54%), and rash in 122 (51%). Forty patients (17%) had comorbidities. Warning signs were observed in 79 patients (33%); 14 (6%) developed severe dengue; 115 (45%) were hospitalized; none died. DENV-1 was the most common serotype. A history of travel and hospitalization prevailed in the first period; severe dengue and prior infection, in the second period. Conclusions. No patient died due to dengue in either study period. Statistically significant differences were observed in the frequency of hospitalization; a history of travel was more common in the 2015-2016 period and severe dengue, in the 2019-2020 period.

Background: Antibiotic-resistant gram-negative bloodstream infections (BSI) remain a leading cause morbidity and mortality in pediatric patients with a high impact on the public health system. Data in resource-limited countries, including those in Latin America and the Caribbean region, are scarce. The aim of the study was to identify risk factors for acquiring carbapenem-resistant Enterobacteriaceae (CRE) bacteremia in children and to assess the use of resources. Methods: A retrospective case-control study was conducted to analyze demographic, epidemiological, clinical, microbiological, and outcome data as well as the use of resources between 2014 and 2019. Univariate and logistic regression analysis was performed in order to identify risk factors associated with CRE-BSI. The R software version 4.1.2 was used. Results: A total of 46 cases with CRE-BSI and 92 controls with gram-negative non-CRE-BSI were included. No statistical difference was observed regarding: median age (36 months; IQR, 11.2-117 vs. 48 months, IQR 13-119), male sex (50 vs. 60%), and underlying disease (98 vs. 91%) in cases vs. controls, respectively. The most frequent mechanism of CRE bacteremia were: KPC in 74%, OXA in 15%, and NDM in 6.5%. A total of 54.3% of cases vs. 32.6 % (p = 0.016) of controls were admitted to the pediatric intensive care unit (PICU), and 48 vs. 21% (p = 0.001) required mechanical ventilation. Bacteremia secondary to intra-abdominal infection was observed in 56.5% of cases vs. 35% of controls (p = 0.032). Previous colonization with CRE was detected in 76% of cases vs. 8% of controls. Combination antimicrobial treatment was most frequent in cases vs. control (100 vs. 56.5%). No difference was observed in median length of hospital stay (22 days; IQR, 19-31 in cases vs. 17.5 days; IQR, 10-31 in controls; p = 0.8). Overall case fatality ratio was 13 vs. 5.5%, respectively. The most statistically significant risk factors included previous PICU stay (OR, 4; 95%CI, 2-8), invasive procedures/surgery (OR, 3; 95%CI, 1-7), central venous catheter placement (OR, 6.5; 95%CI, 2-19), urinary catheter placement (OR, 9; 95%CI 4-20), mechanical ventilation (OR, 4; 95%CI, 2-10), liver transplantation (OR, 8; 95%CI, 2-26), meropenem treatment (OR, 8.4; 3.5-22.6) in univariate analysis. The logistic regression model used for multivariate analysis yielded significant differences for previous meropenem treatment (OR, 13; 95%CI, 3-77; p = 0.001), liver transplantation (OR, 13; 95%CI, 2.5-100; p = 0.006), and urinary catheter placement (OR, 9; 95%CI, 1.4-94; p = 0.03). Conclusion: CRE-BSI affects hospitalized children with underlying disease, mainly after liver transplantation, with previous urinary catheter use and receiving broad-spectrum antibiotics, leading to high PICU requirement and mortality. These risk factors will have to be taken into account in our region in order to establish adequate health policies and programs to improve antimicrobial stewardship.

BACKGROUND: The knowledge of the clinical and evolutionary characteristics of children with SARS-CoV-2 is continuously updated. The true impact of the disease in the pediatric population is still unknown. AIM: To describe the clinical characteristics, the use of resources and the evolution of children with COVID-19 in the Garrahan Pediatric Hospital, Buenos Aires, Argentina, in the first 20 weeks from the identification of the first case. METHODS: Descriptive, analytical, retrospective study. The epidemiological, clinical, evolutionary characteristics and the use of hospital resources of patients < 18 years with confirmed COVID-19 are described. In addition, these characteristics were compared according to whether they occurred in the first 10 epidemiological weeks from the first case of COVID-19 in the hospital or in the following ten weeks. RESULTS: n: 280. The median age was 83 months (IQR 33-144). 209 patients (74.6%) were hospitalized. The median days of hospitalization was 8 days (IQR 3-13). According to the WHO severity classification, there were 184 mild cases (65.7%), 3 moderate (1.1%), 16 severe (5.7%) and 20 critical patients (7.1%). The main reasons for admission to the ICU were not related to SARS-CoV-2 infection. When comparing the characteristics of the patients in the two periods, in the first period there was a higher frequency of underlying comorbidities, immunosuppressive treatment, the consultation was later and the patients had more requirements for ICU admission. Two children (0.7%) died in relation to the infection, both with severe comorbidities and severe bacterial coinfections. CONCLUSION: In this study, patients with underlying disease predominated. The mild form of the disease was the most frequent presentation. At the beginning of the pandemic, there were more patients under immunosuppressive treatment, the consultation was later and the hospitalization was more frequent, prolonged and with more serious clinical pictures.

INTRODUCCIÓN: El conocimiento de las características clínicas y evolutivas de los niños con SARS-CoV-2 está siendo continuamente actualizado. El verdadero impacto de la enfermedad en la población pediátrica es todavía desconocido. OBJETIVO: Describir las características clínicas, el uso de recursos y la evolución de niños con COVID-19 en el Hospital de Pediatría Garrahan, Buenos Aires, Argentina, en las primeras 20 semanas desde la identificación del primer caso. PACIENTES Y MÉTODOS: Estudio descriptivo analítico, retrospectivo. Se describen las características epidemiológicas, clínicas, evolutivas y el uso de recursos hospitalarios de pacientes < 18 años con COVID-19 confirmado. Además, se compararon dichas características según se presentaran en las primeras 10 semanas epidemiológicas desde el primer caso de COVID-19 en el hospital o en las 10 siguientes. RESULTADOS: n: 280. La mediana de edad fue 83 meses (RIC 33-144). Fueron hospitalizados 209 pacientes (74,6 %). La mediana de días de internación fue de 8 días (RIC 3-13). Según la clasificación de gravedad de la OMS, fueron casos leves 184 (65,7%), moderados 3 (1,1%), graves 16 (5,7%) y 20 pacientes críticos (7,1%). Los principales motivos de ingreso a UCI no se relacionaron con la infección por SARS-CoV-2. Al comparar las características de los pacientes en los dos períodos, en el primer período hubo más frecuencia de comorbilidades subyacentes, tratamiento inmunosupresor, la consulta fue más tardía y los pacientes tuvieron más requerimientos de internación en UCI. Fallecieron en relación con la infección dos niños (0,7%), ambos con comorbilidades graves y coinfecciones bacterianas graves. CONCLUSIÓN: En este estudio predominaron los pacientes con enfermedad de base. La forma leve de la enfermedad fue la presentación más frecuente. Al inicio de la pandemia, hubo más pacientes bajo tratamiento inmunosupresor, la consulta fue más tardía y la internación fue más frecuente, prolongada y con cuadros clínicos más graves.
