Profils de résistance des germes responsables d’infections urinaires fébriles de l’enfant et protocoles d’antibiothérapie probabiliste. Une étude épidémiologique au CHRU de Strasbourg et CH de Saverne sur 2019–2020

Abstract

BackgroundFebrile urinary tract infection (UTI) is a common health issue in pediatrics that can lead to serious infectious and renal complications, it requires early diagnosis and a targeted use of antibiotics. The aim of our study was to describe local bacterial agents causing febrile UTIs and their resistance patterns and confront the results with currently used empirical antibacterial therapy in pediatrics emergency departments in Strasbourg and Saverne. Patients and methodsWe used billing codes (international classification of diseases) to identify all inpatients treated for febrile UTIs in two French pediatric emergency departments between January 2019 and December 2020. Microbial results of urine cultures were retrieved from the laboratory information system. ResultsAmong 214 microbial results from 208 patients, the distribution of uropathogens was 82% Escherichia coli, with extended-spectrum beta-lactamase in 2.8%, 7% Enterococcus faecalis, 5% Klebsiella, 2% Proteus mirabilis. E. coli was resistant respectively to amoxicillin, amoxicillin/clavulanic acid and cotrimoxazol in 43, 33 and 14% of samples. A third-generation cephalosporin administered intravenously was mainly used (98%) as empirical treatment. Less than 2% of patients were treated with oral cephalosporin from the start. ConclusionWe present the spectrum of uropathogens and susceptibility test results in pediatric UTIs as well as the susceptibility pattern of E. coli, a local treatment protocol was designed based on our results in conformity with national guidelines.
