[Oral antibiotic treatment of urinary tract infections in children]

Area of Science:

• Pediatrics
• Infectious Diseases
• Pharmacology

Context:

• Urinary tract infections (UTIs) are highly prevalent in pediatric populations.
• Escherichia coli (E. coli) is the predominant pathogen causing UTIs in children.
• Antibiotic selection for UTIs requires consideration of clinical presentation, oral administration feasibility, and local antimicrobial resistance patterns.

Purpose:

• To provide updated guidance on empiric antibiotic therapy for childhood UTIs.
• To address the challenge of increasing E. coli resistance to common antibiotics.
• To recommend specific first-line oral antibiotic agents for upper and lower UTIs in children.

Summary:

• Most childhood UTIs, both upper and lower, can be safely managed with oral antibiotics.
• Pivmecillinam or amoxicillin-clavulanic acid are recommended as first-line oral therapies for upper UTIs.
• Nitrofurantoin is identified as a preferred first-choice oral agent for lower UTIs, while amoxicillin and trimethoprim-sulfamethoxazole are less recommended due to resistance.

Impact:

• This guidance aims to optimize UTI treatment outcomes in children by promoting effective antibiotic use.
• The recommendations address the growing concern of antimicrobial resistance in pediatric E. coli infections.
• The study highlights the need for developing pediatric antibiotic formulations, such as syrups, in markets like Norway to improve medication adherence and efficacy.
