Summary
Pediatric urinary tract infections show high resistance to common antibiotics like ampicillin. This study analyzed antimicrobial susceptibility in young patients, revealing concerning trends in antibiotic resistance.
Area of Science:
- Pediatric infectious diseases
- Antimicrobial resistance
- Clinical microbiology
Background:
- Urinary tract infections (UTIs) are common in children.
- Antibiotic resistance in pediatric uropathogens is a growing concern.
- Understanding susceptibility patterns is crucial for effective UTI treatment in children.
Purpose of the Study:
- To determine antimicrobial susceptibility patterns of common pediatric uropathogens.
- To assess resistance rates to six frequently used antibiotics for UTIs in children.
- To stratify resistance data by pediatric age groups and sex.
Main Methods:
- Analysis of bacterial isolates from urine cultures of pediatric outpatients (April 2002-May 2004).
- Inclusion of the six most common uropathogens.
- Stratification of results by pediatric age group and sex.
Main Results:
- High overall resistance rates were observed: ampicillin (44.3-44.6%), sulfamethoxazole/trimethoprim (24.5-36.7%).
- Lower but notable resistance to amoxicillin/clavulanic acid (12.4-27.5%) and cefazolin (10.9-27.1%).
- Ciprofloxacin (0.9-2.4%) and nitrofurantoin (4.4-11.0%) showed lower resistance rates.
Conclusions:
- Pediatric uropathogens exhibit high resistance to several commonly prescribed antibiotics for UTIs.
- Significant sex-based differences in resistance rates were noted for most antibiotics.
- These findings highlight the need for regular surveillance and updated treatment guidelines for pediatric UTIs.
