Antibiotics for acute pyelonephritis in children

Area of Science:

• Pediatric Nephrology
• Infectious Diseases
• Clinical Pharmacology

Background:

• Urinary tract infections (UTIs) are common in infants, with acute pyelonephritis being the most severe form.
• Acute pyelonephritis can lead to significant morbidity and permanent kidney damage.
• Current guidelines recommend initial intravenous (IV) followed by oral antibiotic therapy, but optimal duration remains unclear.

Purpose of the Study:

• To evaluate the benefits and harms of various antibiotic regimens for treating acute pyelonephritis in children.
• To compare different antibiotic agents, routes, frequencies, and durations of therapy.

Main Methods:

• Systematic review of randomized and quasi-randomized controlled trials.
• Searched major databases (Cochrane, MEDLINE, EMBASE) without language restrictions.
• Data extraction and quality assessment by two independent reviewers; random-effects model used for analysis.

Main Results:

• No significant difference in renal damage or fever duration between 14-day oral cefixime and 3-day IV followed by 10-day oral therapy.
• No significant difference in renal damage between 3-4 day IV followed by oral therapy and 7-14 day IV therapy.
• Efficacy of daily versus thrice-daily aminoglycoside administration showed no significant difference.

Conclusions:

• Children with acute pyelonephritis can be effectively treated with oral cefixime or short-course IV therapy (2-4 days) followed by oral antibiotics.
• Single daily dosing of aminoglycosides is a safe and effective IV option.
• Further trials are needed to determine optimal total therapy duration and the role of other oral antibiotics in initial treatment.
