RESUMEN
RESUMEN El tratamiento empírico para la infección urinaria se ve complicado frente a la presencia de multirresistencia y de betalactamasas de espectro extendido (BLEE). El objetivo del estudio fue describir los patrones de resistencia antibiótica de cepas de Escherichia coli aisladas en urocultivos y los factores clínico-epidemiológicos asociados a la presencia de BLEE en un grupo pediátrico y adulto. Se recolectaron durante 14 meses, 353 cepas provenientes de Emergencia y Hospitalización del Hospital Cayetano Heredia, 45,9% fueron cepas multirresistentes. La incidencia de BLEE en población pediátrica fue 16,3% vs. 31,1% en la adulta, el 63,6% provenía de pacientes ambulatorios. La presencia de BLEE se asoció con encontrarse hospitalizado en pediatría, así cómo al uso de pañal y vejiga neurogénica en adultos. Estos factores deben considerarse al momento de elegir un tratamiento antibiótico. Asimismo, es necesario implementar programas de reporte epidemiológico y modelos de prevención de factores de riesgo.
ABSTRACT
ABSTRACT The empirical treatment of urinary infections is complicated by the presence of multiresistance and resistance to extendedspectrum beta-lactamases (ESBLs). The objective of this study was to describe the patterns of antibiotic resistance of Escherichia coli strains isolated from urine cultures and the clinical-epidemiological factors associated with the presence of ESBLs in a pediatric and an adult group. A total of 353 strains were collected from the Emergency and Hospitalization Sector of the Cayetano Heredia Hospital over 14 months, and 45.9% of the isolated strains were multiresistant. The rate of resistance to ESBLs in the pediatric and adult population was 16.3% and 31.1%, respectively, and 63.6% of the resistant strains were isolated from outpatients. The presence of ESBLs was associated with hospitalization in pediatrics, use of diapers, and the presence of neurogenic bladder in adults. These factors should be considered in selection of an antibiotic treatment. Moreover, epidemiological reporting programs and models should be implemented for reduction of risk factors.
