Urinary tract infection (UTI) is a common childhood disease with a prevalence of 7.8% that can lead to serious complications including renal scarring.1 Approximately 80% of UTIs in children are caused by Escherichia coli that are unfortunately accompanied by an increased prevalence of extended-spectrum beta-lactamases (ESBL) - producing strains.2,3 This study tries to determine the incidence of ESBL-producing Enterobacteriaceae (PE) UTIs among the pediatric population in Qatar, and predict the relation between multiple antibiotics exposure, antibiotic prophylaxis, recurrent UTIs, prior hospitalizations, prior urinary tract abnormalities as risk factors, and the development of ESBL-PE UTI in the same population. This is a retrospective case control and cross-sectional study conducted over a period of one year from January 2018 to January 2019. The inclusion criteria were infants and children from 0 month to 14 years old diagnosed with community-onset of urinary tract infection however, exclusion criteria were immunocompromised or cancer patients. Case group was defined as patients who developed ESBL-PE UTI (n = 135), while the control group were patients who developed sensitive Enterobacteriaceae UTI (n = 219). 406 patients were included, 33% of them had ESBL-PE UTI (Figure 1) and 51 were excluded (infection caused by another organism) (Figure 1). Regarding antibiotics exposure during the preceding 6 months, 28% of the case group patients were prescribed multiple courses of antibiotics versus 10% in the control group. 21% within the case group patients received antibiotic prophylaxis versus 6% in the control group. Furthermore, 21% of case group patients were diagnosed with urinary tract anomalies versus 4.5% in the control group, however no significant statistical difference regarding UTI recurrence was found (p>0.05). 17% of case group patients were hospitalized previously versus 7% in the control group (Table 1). The study found that ESBL-PE UTI incidence among pediatric patients was high. Repeated exposure to antibiotics courses, antibiotic prophylaxis, previous hospitalization, and prior UT anomalies may have an impact on this resistance rate.
