Aislamiento de bacterias productoras de BLEE en pacientes con reflujo vesicoureteral en el Hospital Roberto Gilbert Elizalde durante el periodo enero del 2018 a julio del 2021.

Abstract

Introduction The presence of microorganisms producing extendedspectrum beta-lactamase (BLEE) is a health problem that has increased in recent years, it is associated with the inappropriate use of antibiotics; the urinary tract is a common sources of infection in the pediatric population, with vesicoureteral reflux being a predisposing factor for the colonization of these bacteria, there is variability in the management of these patients with a similar degree of reflux in terms of the use or not of antibiotic prophylaxis , in addition to bladder catheterization and associated comorbidities that increase the risk of infection by ESBL-producing microorganisms, the objective of this study was to determine the prevalence of these bacteria in non-hospitalized patients with vesicoureteral reflux and their clinical characteristics. Methods a quantitative, observational, descriptive, cross-sectional and retrospective design study was carried out, which included patients with vesicoureteral reflux documented by cystourethrography and urine cultures with isolation of bacteria during the period January 2018 - July 2021 attended at the Roberto Gilbert Elizalde Hospital. Results 101 isolated urine cultures were reported, 73% were BLEE producers, being in order of frequency E coli BLEE, followed by Klebsiella pneumoniae, the most affectes sex was female, and the predominant age group preschool. Conclusions It was determined that there is greater isolation of BLEE production bacteria in patients who received antibiotic prophylaxis, had associated comorbidity and was acquired in the community.
