Summary: | ABSTRACT Objective The increase in antibiotic resistance (AR) is a global phenomenon with regional variation. This survey aims to describe the AR in urine cultures of women from the community in a southern Brazil city. Methods A retrospective cross-sectional single-center study in urine cultures of community dwelling individuals. The main outcome was the AR profile of bacterial isolates from women in outpatient care. Results From 4,011 urine cultures, 524 were positive (91% from women). The most frequently isolated bacteria were Escherichia coli (E. coli) (67.0%) and Klebsiella spp. (19.4%). E. coli presented low resistance to nitrofurantoin (3.7%), moderate to levofloxacin (15.6%), amoxacillin-clavulonate (16.4%) and ciprofloxacin (17.4%), and high to trimethoprim-sulfamethoxazole (26.9%). Conclusions Nitrofurantoin seems to be the best choice for the empirical treatment of low urinary tract infections in women, whereas sulfonamides are no longer an option, since E. coli resistance to this drug is above 20%.
RESUMEN Objetivo El aumento de la resistencia a los antibióticos (AR) es un fenómeno global con variaciones regionales. Esta investigación tiene como objetivo describir la AR en cultivos de orina de mujeres de la comunidad de una ciudad del sur de Brasil. Métodos Un estudio retrospectivo transversal, de un solo centro, de cultivos de orina de la comunidad. El resultado principal fue el perfil de AR de bacterias aisladas de estos cultivos de orina. Resultados De 4.011 cultivos de orina, 524 fueron positivos (91% de las mujeres). Las bacterias más frecuentemente aisladas en mujeres fueron Escherichia coli (67,0%) y Klebsiella spp. (19,4%). E. coli mostró baja resistencia a nitrofurantoína (3,7%), moderada a levofloxacina (15,6%), amoxacilina-clavulonato (16,4%) y ciprofloxacina (17,4%) y alta a trimetoprima-sulfametoxazol (26,9%) entre las mujeres. Conclusiones La nitrofurantoína parece ser la mejor opción para el tratamiento empírico de la infección de las vías urinarias inferiores en mujeres, mientras que las sulfonamidas ya no son una opción, ya que la resistencia de E. coli a este fármaco es superior al 20%.
