摘要

Urinary tract infections (UTI) affect between 3% to 7.5% of the febrile pediatric population each year, being one of the most common bacterial infections in pediatrics. Nevertheless, there is no consensus in the medical literature regarding the duration of per oral (p.o.) antibiotic therapy for UTI among these patients. Therefore, our meta-analysis aims to assess the most effective therapy length in this scenario. PubMed, Cochrane, and Embase were searched for randomized controlled trials (RCTs) comparing short (≤ 5 days) with long-course (≥ 7 days) per os (p.o.) antibiotic therapy for children with UTI. Statistical analysis was performed using R Studio version 4.2.1, heterogeneity was assessed with I² statistics, and the risk of bias was evaluated using the RoB-2 tool. Risk Ratios (RR) with p < 0.05 were considered statistically significant. Seventeen studies involving 1666 pediatric patients were included. Of these, 890 patients (53.4%) were randomized to receive short-course therapy. Patients undergoing short-course therapy showed higher treatment failure rates (RR 1.61; 95% CI 1.15–2.27; p = 0.006). Furthermore, there were no statistically significant differences between groups regarding reinfection (RR 0.73; 95% CI 0.47–1.13; p = 0156) and relapse rates (RR 1.47; 95% CI 0.8–2.71; p = 0.270).

Conclusion: In summary, our results suggest that long-course p.o. antibiotic therapy is associated with a lower rate of treatment failure when compared to short-course p.o. antibiotic therapy. There was no statistical difference between both courses regarding reinfection and relapse rates within 15 months.

PROSPERO identifier: CRD42023456745.

What is Known:

• Urinary tract infections (UTIs) are common in children, affecting around 7.5% of those under 18.

• The optimal duration of antibiotic treatment for pediatric UTIs has been a subject of debate.

What is New:

• Short-course therapy (5 or fewer days) was associated with a significantly higher failure rate when compared to long-course therapy.

• There was no significant difference in reinfection and relapse rates within 15 months between short and long-course therapy.
