Increasing antibiotic resistance among urinary tract isolates

Area of Science:

• Pediatric Nephrology
• Infectious Diseases
• Clinical Microbiology

Background:

• Urinary tract infections (UTIs) are common in children.
• Children with underlying renal problems may face increased risks and complications from UTIs.
• Antimicrobial resistance is a growing global health concern, particularly in pediatric populations.

Purpose of the Study:

• To determine the spectrum of organisms causing UTIs in children.
• To compare antimicrobial susceptibility patterns between community-residing children and those with renal conditions.
• To identify specific antibiotic resistance trends, especially for commonly prescribed agents like trimethoprim.

Main Methods:

• A five-year retrospective study design.
• Analysis of urinary tract isolates from 2815 community children and 1314 children with underlying renal problems.
• Evaluation of antimicrobial susceptibility testing results for isolated organisms.

Main Results:

• Isolates from children with underlying renal problems demonstrated greater resistance to common antibiotics compared to community isolates.
• Escherichia coli (E. coli) isolates from children with renal disease showed significantly higher resistance to trimethoprim (nearly two-thirds) than those from community children (up to one-third).

Conclusions:

• Children with underlying renal conditions experience UTIs caused by more resistant organisms.
• Trimethoprim resistance in E. coli is a significant issue in pediatric UTIs, especially in vulnerable populations with renal disease.
• Antimicrobial stewardship and surveillance are crucial for managing pediatric UTIs effectively.
