- Abstract
- Purpose: The purpose of this study was to investigate the clinical characteristics and outcome of febrile urinary tract infections (UTIs) caused by community-acquired extended-spectrum β-lactamase (CA-ESBL)-producing and -nonproducing bacteria. Methods: We analyzed febrile UTIs in children hospitalized at Gachon University Gil Medical Center from January 2011 to December 2013 through retrospective data collection from their medical records. Results: Among pathogens causing 374 episodes of UTIs, the proportion of ESBL-producing bacteria was 13.1% (49/374). The proportion of ESBL-producing Escherichia coli and Klebsiella spp. was 13.6% (48/354) and 5.0% (1/20), respectively. There was no significant difference between the CA-ESBL and CA non-ESBL groups in duration of fever (4.2±2.7 vs.3.7±2.1 days, P =0.10) and bacterial eradication rate with empirical antibiotics (100% vs. 100%). The risk of cortical defects on renal scan significantly depended on existence of vesicoureteral reflux rather than ESBL production of pathogen. Conclusions: There was no significant difference between the CA-ESBL and CA non-ESBL groups in renal cortical defects and clinical outcome. Careful choice of antibiotics is important for treatment of community-acquired UTI in children. © 2015, Korean Society of Pediatric Infectious Diseases. All rights reserved.
