ObjectiveThe aim of this study was to determine the bacterial profile and prevalence of antibiotic resistance patterns of uropathogens, as well as to evaluate the problem with extended-spectrum β-lactamases (ESBLs)-producing isolates, causing urinary tract infections (UTIs) in children in Al-Amiri Hospital, Kuwait, over a 5-year period.Materials And MethodsSignificant isolates from symptomatic pediatric patients with UTIs from January 2017 to December 2021 were identified by conventional methods and by the VITEK 2 identification card system. Antimicrobial susceptibility testing was performed by the disk diffusion method for Gram-positive organisms and an automated VITEK 2 system for Gram-negative organisms. ESBL-producing Enterobacterales were detected by the double-disk diffusion method and VITEK 2 system.ResultsSignificant bacteriuria was detected in 13.7% of the 9,742 urine samples. Escherichia coli accounted for 67.3% of these, followed by Klebsiella pneumoniae (8.9%), Proteus spp. (5.7%), and Enterococcus spp. (7.4%), respectively. High resistance rates were observed among the Enterobacterales against ampicillin, cephalothin, nitrofurantoin, amoxicillin/clavulanic acid, and trimethoprim-sulfamethoxazole. The prevalence of ESBL-producing E. coli and K. pneumoniae was 26% and 55%, respectively. The most sensitive among the antibiotics tested for Gram-negative organisms were meropenem, amikacin, gentamicin, and piperacillin/tazobactam, while the antibiotics tested for Gram-positive organisms were vancomycin, ampicillin, linezolid, and nitrofurantoin.ConclusionE. coli remains the most common uropathogen. A high percentage of uropathogens causing UTI in children were highly resistant to the first- and second-line antibiotics for the therapy of UTI. ESBL-producing bacteria were highly prevalent in children in our hospital. Local antibiograms should be used to assist with empirical UTI treatment.© 2022 The Author(s). Published by S.
