Abstract
To investigate the multidrug resistance (MDR) patterns of Escherichia coli causative of urinary tract infections (UTI) in patients attending a tertiary university hospital of Rio de Janeiro, Brazil. Antibiotic susceptibility testing was performed by the disk diffusion method. MDR, extensively-resistance (XDR) and pan-resistance (PDR) were defined by using recently described criteria. Retrospective analyses of clinical, microbiological and demographic features of outpatients and inpatients with UTI (n=416) were also performed. High antibiotic resistance rates for trimethoprimsulfamethoxazole - SXT-TMP (n=177; 46.7%) and fluoroquinolones - FQ [n=117; norfloxacin (27%) and ciprofloxacin (26.8%) – (FQ) were demonstrated for E. coli strains isolated from community and healthcare-onsets. Risk factors associated with UTIs due to MDR E. coli isolates included prior three-month hospitalization (OR: 2.4; CI 95%: 1.3-4.4; p<0.005), presence of neurogenic bladder (OR: 3.7; CI 95% :1.7-8.3; p<0.01 ) and kidney transplantation (OR: 3.1; CI 95%:1-0.5; p<0.04). A high prevalence of community-acquired and nosocomial urinary tract infections due SXT-TMP/ FQ resistant E. coli strains was observed in Rio de Janeiro metropolitan area, Brazil. According to IDSA Guidelines, initial empirical therapy for community-associated UTI with SXT-TMP and FQ should be avoided in Rio de Janeiro. Nitrofurantoin, amoxicillin/clavulanic, piperacillin/tazobactam or gentamicin associations were effective for the empiric therapy for community-acquired and healthcare-associated UTIs, respectively.
