Infecciones del tracto urinario: etiología y susceptibilidades antimicrobianas

Abstract

Introducción: la infección del tracto urinario (ITU) es una de las enfermedades más prevalentes en la práctica clínica. Con el fin de mejorar el tratamiento empírico, se ha estudiado la etiología de las infecciones urinarias en Pediatría y el perfil de sensibilidad antibiótica de los microorganismos responsables. Material y métodos: estudio transversal, descriptivo y retrospectivo (2020-2021), en el que se incluyeron los microorganismos aislados con recuento significativo en muestras de orina de pacientes con ITU. Se analizó la etiología global y en función de la edad y el sexo. Se consideró únicamente una muestra de orina por paciente y episodio de ITU. Resultados: Escherichia coli fue el microorganismo más aislado tanto en el conjunto de la población (62%) como en cada uno de los grupos analizados según edad y sexo. Su aislamiento en mujeres fue significativamente superior que en hombres (χ², p = 0,043). Su sensibilidad fue: 94% a fosfomicina y 86% a amoxicilina-ácido clavulánico. Conclusiones: Escherichia coli continúa siendo el microorganismo más frecuentemente aislado en ITU. Por ello, para las ITU bajas, la amoxicilina-clavulánico y la nitrofurantoína podrían ser opciones adecuadas. Nuestro medio debería recomendar fosfomicina, ya que muestra varias ventajas para su uso, como la dosificación una vez al día, bajos efectos secundarios, resultados clínicos y microbiológicos adecuados y poco efecto sobre la microbiota intestinal.

Introduction: urinary tract infection (UTI) is one of the most prevalent diseases in clinical practice. In order to improve empirical treatment, the etiology of pediatric urinary tract infections and the antibiotic sensitivity profile of the responsible microorganisms have been studied. Material and methods: cross-sectional, descriptive and retrospective study (2020-2021) in which isolated microorganisms with significant counts in urine samples from patients with UTI were included. The global etiology and according to age and sex were analyzed. Only one urine sample per patient and UTI episode was considered. Results: Escherichia coli was the most isolated microorganism both in the population as a whole (62%) and in each of the groups analyzed according to age and sex. It was isolated in women significantly higher than in men (χ², p=0.043). Their sensitivity was: 94% fosfomycin and 86% amoxicillin-clavulanic acid. Conclusions: Escherichia coli continues to be the most frequently isolated microorganism in UTI. Therefore, for lower UTIs, amoxicillin-clavulanic acid and nitrofurantoin could be suitable options. Our environment should recommend fosfomycin, since it shows several advantages for its use, such as once-daily dosing, low side effects, adequate clinical and microbiological results, and little effect on the intestinal microbiota.
