Has the COVID-19 Pandemic Affected Community-Acquired Urinary Tract Infections in Children?

To evaluate whether there were any changes in the rates of urinary tract infection (UTI) and antibiotic resistance in pediatric patients during the pandemic period.

Urine culture samples collected due to suspected UTI were searched retrospectively from our hospital database, and the patients with growth in urine culture were identified. They were divided into 2 groups as Group A (before COVID-19, March 11, 2019- March 11, 2020) and Group B (COVID-19 period, March 11, 2020- March 11, 2021). Also, COVID-19 period was divided into 3 subgroups (March 2020- June 2020: first epidemic peak, July 2020 - November 2020: normalization process, December 2020- March 2021: second epidemic peak). We adjusted the patient age as <1, 1-6 and 7-18 years. Age, gender, microorganism strain types, and their antibiotic resistance patterns were compared between the 2 groups Results: This cross-sectional study included 250 eligible patients (Group A, n=182 and Group B, n=68) with a mean age of 10.91 ± 5.58 years. The male/female ratio was higher in Group B than in Group A (p = .004). Incidence of UTIs was lower in the curfew and restriction periods due to epidemic peaks than normalization process (p = .001). The proportion of E.coli decreased from 80.2% to 61.8% during the pandemic period when compared to pre-pandemic period (p = .001). Group B had lower rates of resistance to ampicillin, fosfomycin and nitrofurantoin for E.coli than Group A (p = .001, p = .012 and p = .001, respectively). Also, Group B had higher rate of uncommon microorganisms and lower rate of resistance to nitrofurantoin for E.coli than Group A in patients aged 7-18 years (p = .003 and p = .023, respectively).

Our study demonstrates that the ongoing COVID-19 pandemic process has caused alterations in community-acquired UTIs in children. More hygienic lifestyle may be considered as the main factor in this change.
