Uncomplicated urinary tract infection in women: etiology and antimicrobial resistance
Abstract
Our objectives were to determine the etiology and analyze the antibiotic resistance profiles of microorganisms causing uncomplicated urinary tract infections in our setting. An analytical cross-sectional study was conducted. In vitro antimicrobial resistance of urine cultures was analyzed. 580 urine cultures of women over age fifteen were included. 82.6 % of urine cultures corresponded to cystitis and the remaining 17.4 % corresponded to pyelonephritis. 353 urine cultures of women <50 years old (60.9%) and 227 of women = 50 years old (39.1%) were obtained. The most common pathogens were Escherichia coli (85.5 %) and Klebsiella pneumoniae (4.7 %). For Escherichia coli, there was a resistance of 28.6% to trimethoprim-sulfamethoxazole,7.9% to ciprofloxacin and 0.4% to nitrofurantoin. Significant difference (p = 0.005) was seen in the resistance to ciprofloxacin in women = 50 years old. Our data show there is a low in vitro resistance to nitrofurantoin
Nuestros objetivos fueron determinar la etiología y analizar los perfiles de resistencia antimicrobiana de los microorganismos causantes de infecciones urinarias no complicadas en nuestro medio. Se realizó un estudio analítico de corte transversal. Se analizó la resistencia antimicrobiana in vitro de los urocultivos. Se incluyeron 580 urocultivos de mujeres mayores de 15 años. Un 82.6% de urocultivos correspondieron a cistitis y el 17.4% a pielonefritis.Se obtuvieron 353 urocultivos de mujeres < 50 años (60.9%) y 227 a ? 50 años…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 227 participants or records.
