Community-acquired urinary tract infections in children: Resistance patterns of uropathogens in a tertiary care center in Saudi Arabia.

OBJECTIVE

The aim of the present study was to investigate the bacterial pathogens and their resistance patterns in children presenting with their first admission for a urinary tract infection (UTI) in a large tertiary care center in Riyadh, Saudi Arabia.

METHODS

A retrospective chart review was conducted of pediatric patients 0-14 years of age who were admitted for their first community-acquired UTI in a large tertiary care center in Riyadh, Saudi Arabia. The review covered a 6-year period (2006-2012).

RESULTS

Data were obtained from 202 children, of which 162 (80.2%) were female. The most frequently isolated uropathogens were (75.7%), followed by (9.4%), (5.9%) and species (3.5%). Sixteen (7.9%) isolates were ESBLs. Among all uropathogens, 68% were resistant to ampicillin, 54% resistant to co-trimoxazole, and 30% resistant/intermediate sensitivity to amoxicillin/clavulinic acid. Overall, there was a low resistance rate to cefotaxime (4.4%).

CONCLUSION

is the predominant uropathogen causing UTIs in children, yet there is a high rate of multidrug-resistant organisms. For children admitted for a community-acquired UTI, a third-generation cephalosporin remains an appropriate empiric antibiotic. Our study and the work of others emphasize the importance of choosing empiric antibiotics for pediatric UTIs based on local resistance patterns.
