Abstract

PURPOSE
We aimed to determine characteristics of host, causative organisms, and antibiotic susceptibility of bacteria in pediatric patients with UTI living in metropolitan area of Korea.
METHODS
Retrospective investigation was done for the causative organisms of UTI in 683 pediatric cases treated at Ajou University Hospital from 2012 to 2017. Patients were classified into Escherichia coli and non-E.coli group, where E.coli group was subdivided into ESBL(+) and ESBL(−) groups based on whether the bacteria could produce extended spectrum beta-lactamase (ESBL). Antibiotic susceptibility of the causative organism was also determined.
RESULTS
A total of 683 UTIs occurred in 550 patients, of which 463 (67.8%) were first-time infection and 87 (32.2%) were recurrent ones (2-7 recurrences, 2.52 average), and 64.9% were male and 35.1% were female. The most common causative organism was E.coli (77.2%) and ESBL(+) E.coli was found in 126 cases. The susceptibility of E.coli to 3rd or 4th generation cephalosporin was relatively higher than that to ampicillin or amoxicillin/clavulanic acid. ESBL(+) E.coli showed higher resistance rate to 3rd or 4th generation cephalosporin than ESBL(−) E.coli .
CONCLUSION
New treatment guideline should be considered due to the incidence of ESBL(+) E.coli increased up to one quarter of UTI cases.
