RESUMO

BACKGROUND: The epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-susceptible S. aureus (MSSA) has changed in recent years. The present article is intended to establish differences between clinical, laboratory and imaging findings and outcomes of MSSA and MRSA infections, as well as among subgroups of infection such as skin and soft tissue infection, osteoarticular, bacteremia or pneumonia in a pediatric population from Bogota, Colombia. METHODS: Retrospective cohort study using clinical records of patients under 18 years of age treated at the participating centers in Bogota, Colombia, between 2014 and 2018. The first positive S. aureus culture was studied. MSSA and MRSA were compared. The χ2 test, Fisher exact test, and Kruskal-Wallis test were calculated, and the statistical significance was presented using the difference and its 95% CI. RESULTS: Five hundred fifty-one patients were included; 211 (38%) corresponded to MRSA and 340 (62%) to MSSA for a total of 703 cultures. A significantly higher probability of having an MSSA infection than MRSA was found in patients with previous heart disease (3.3% vs. 0.5%), neurologic disease (5.9% vs. 2.5%), recent major surgeries (11% vs. 5%) or who has an implanted device (11% vs. 4%). In contrast, in severe MRSA infections (bacteremia, osteoarticular infections and pneumonia), a higher rate of complications was seen (admission to the pediatric intensive care unit, mechanical ventilation and vasoactive support), and in osteoarticular MRSA, more than 1 surgery per case was seen (89% vs. 61%). Laboratory results and mortality were similar. CONCLUSIONS: MRSA was associated with a more severe course in bacteremia, osteoarticular infections and pneumonia. Some classical risk factors associated with MRSA infections were found to be related to MSSA. In general, with the exception of skin and soft tissue infection, there was an increased risk of pediatric intensive care unit admission and mechanical and inotropic support with MRSA in a pediatric population.

RESUMO

Introducción: las infecciones del tracto urinario son un problema frecuente en la población pediátrica. La infección del tracto urinario recurrente tiene mayor riesgo de cicatrices renales y daño glomerular. Objetivo: describir la frecuencia de hematuria, presencia de proteínas en orina, elevación en tensión arterial y hallazgos ecográficos en pacientes pediátricos desde 1 mes hasta 14 años de edad, con diagnóstico de infección del tracto urinario. Métodos: estudio descriptivo transversal, realizado entre octubre de 2014 y febrero de 2016, en pacientes que asistieron al servicio de urgencias pediátricas del Hospital de San José, con diagnóstico de infección del tracto urinario. Resultados: se diagnosticaron 125 pacientes con infección del tracto urinario, la mediana de edad fue de 2,75 años, más frecuente en mujeres (75,2 por ciento) y la mayoría recibió tratamiento intrahospitalario (58,4 por ciento). Se observó que en el grupo de infección del tracto urinario recurrente fue más frecuente el hallazgo de hematuria, que en la infección del tracto urinario primer episodio (21,9 vs. 11,8 por ciento), al igual que las malformaciones renales (32,0 vs. 14,5 %). En la tensión arterial no se observaron grandes diferencias entre los grupos, con una frecuencia de tensión arterial elevada en hospitalizados de 19,6 por ciento para primer episodio, y 18,2 por ciento en recurrentes. La presencia anormal de proteínas en orina fue de 35,4 por ciento en el grupo de infección del tracto urinario primer episodio. Conclusiones: son frecuentes la presencia de hematuria, malformaciones renales y elevación de la tensión arterial en pacientes con infección del tracto urinario. Se encuentra una frecuencia inusual de pacientes con elevación de la presión arterial y proteínas en orina, probablemente por falsos positivos. Se debe insistir en seguimiento ambulatorio del uroanálisis y la tensión arterial, para garantizar que esta se normalice o para detectar daños permanentes(AU)


Introduction: urinary tract infections are a frequent problem in the pediatric population. Recurrent urinary tract infection has a higher risk of kidney scars and glomerular damage. Objective: to describe frequency of hematuria, presence of proteins in urine, increase of blood pressure, and ultrasound findings in pediatric patients from 1 month to 14 years old with a diagnosis of urinary tract infection. Methods: cross-sectional descriptive study conducted from October 2014 to February 2016, in patients who attended the pediatric emergency´s service of the Hospital of San José with a diagnosis of urinary tract infection. Results: 125 patients with urinary tract infection were diagnosed, the median age was 2.75 years, it was more frequent in women (75.2 percent) and the majority of them received intrahospital treatment (58.4 percent). It was observed that in the recurrent urinary tract infection group the finding of hematuria was more frequent, than in the group of urinary tract infection as a first episode (21.9 vs. 11.8 percent), as well as the renal malformations (32,0 vs. 14.5percent). In blood pressure, there were no large differences among the groups, with a rate of high blood pressure frequency in hospitalized patients of 19.6 percent for first episode, and 18.2 percent in recurrent patients. The abnormal presence of proteins in urine was of 35.4 percent in the group of urinary tract infection first episode(AU) Conclusions: the presence of hematuria, renal malformations and increase of blood pressure in patients with urinary tract infection are frequent. There is an unusual frequency of patients with high blood pressure and proteins in the urine, probably due to false positives. It must be addressed the ambulatory monitoring of urinalysis and blood pressure to ensure that it normalizes or to detect permanent damage
