The Clinical Efficacy and Safety of Ertapenem for the Treatment of Complicated Urinary Tract Infections Caused by ESBL-Producing Bacteria in Children

摘要

Background. Urinary tract infections (UTIs) are common and important clinical problem in childhood, and extended-spectrum-beta-lactamase- (ESBL-) producing organisms are the leading cause of healthcare-related UTIs. In this study, we aimed to evaluate the clinical efficacy and safety of ertapenem therapy in children with complicated UTIs caused by ESBL-producing organisms.Methods. Seventy-seven children with complicated UTIs caused by ESBL-producing organisms were included in this retrospective study, and all had been treated with ertapenem between January 2013 and June 2014.Results. Sixty-one (79%) females and sixteen (21%) males with a mean ± standard deviation (SD) age of76.6±52months (range 3–204, median 72 months) were enrolled in this study.Escherichia coli(E. coli) (n=67; 87%) was the most common bacterial cause of the UTIs followed byKlebsiella pneumoniae(K. pneumoniae) (n=9; 11.7%) andEnterobacter cloacae(E. cloacae) (n=1; 1.3%). The mean duration of the ertapenem therapy was8.9±1.6days (range 4–11). No serious drug-related clinical or laboratory adverse effects were observed, and the ertapenem therapy was found to be safe and well tolerated in the children in our study.Conclusion. Ertapenem is a newer carbapenem with the advantage of once-daily dosing and is highly effective for treating UTIs caused by ESBL-producing microorganisms.
