Evaluation of short-term antibiotic therapy in children with uncomplicated urinary tract infections

Area of Science:

• Pediatrics
• Infectious Diseases
• Clinical Pharmacology

Background:

• Urinary tract infections (UTIs) are common in children.
• Identifying optimal antibiotic treatment duration is crucial for effective management.
• Serum C-reactive protein (CRP) levels may help stratify UTI severity and predict treatment response.

Purpose of the Study:

• To evaluate if serum C-reactive protein (CRP) concentrations can identify children with uncomplicated lower UTIs who benefit from short-term antibiotic therapy.
• To compare the efficacy of one-day versus ten-day cefadroxil regimens in CRP-negative children.
• To assess the overall effectiveness of short-term versus conventional antibiotic therapy for pediatric UTIs based on CRP levels.

Main Methods:

• Randomized controlled trial involving 80 children with CRP-negative UTIs (CRP < 28 µg/ml) assigned to one-day or ten-day cefadroxil.
• 44 children with CRP-positive UTIs (CRP ≥ 28 µg/ml) received ten-day cefadroxil.
• Clinical and laboratory data were collected, and recurrence rates were monitored post-therapy.

Main Results:

• Recurrent infections were significantly higher in CRP-negative children receiving one day (44.4%) versus ten days (20%) of cefadroxil.
• Combined data showed 79% recurrence after short-term (1-4 days) vs. 41% after ten-day therapy in CRP-negative children.
• Overall recurrence rates were higher with short-term therapy (48%) compared to conventional ten-day therapy (34%) across both studies.

Conclusions:

• Short-term antibiotic therapy is less effective than a ten-day regimen for children with CRP-negative UTIs.
• CRP levels can help guide treatment decisions, with shorter courses associated with higher recurrence rates.
• Conventional ten-day antibiotic therapy remains the preferred approach for pediatric UTIs to minimize recurrence.
