Abstrakt:	Background: Urinary tract infections (UTIs) are a frequent disorder of childhood, mainly caused by Escherichia coli. The aim of this study was to evaluate the antimicrobial susceptibility trend in bacterial isolates in urine cultures in pediatric environment, analyzing data from our laboratory in a 6-year period. Methods: A retrospective study was performed in AO SS. Antonio e Biagio e Cesare Arrigo (Pediatric Hospital) of Alessandria in Piedmont, North Ital. From 2015 to 2020, in a 6-year period, 1299 urinocultures were collected. Data collection was focused on demographic characteristics (age and sex) and laboratory findings (positive urocultures, antibiogram). Results: Positive urocultures were 577, in which Escherichia coli represented most isolates (428, 74.2%). We found a statistically significant trend toward amoxiclavulanate resistance in the E. coli positive urinoculture comparing the period 2015-2018 vs. 2019-2020. Conclusions: Actual guidelines mostly recommend for amoxicillin-clavulanate prescription as first-line option for pediatric UTI management, this indication might be partially reconsidered. Our data underline the importance to conduct surveillance studies to determine local prevalence of antibiotic resistance to optimize therapeutic management.
