Outcomes in children with vesicoureteral reflux receiving antibiotic prophylaxis

Area of Science:

• Pediatric Nephrology
• Infectious Diseases
• Urology

Background:

• Vesicoureteral reflux (VUR) in children is a common condition.
• The use of antibiotic prophylaxis to prevent recurrent urinary tract infections (UTIs) in these patients is controversial.
• Understanding the efficacy of prophylaxis is crucial for clinical decision-making.

Purpose of the Study:

• To evaluate the effectiveness of antibiotic prophylaxis in children diagnosed with VUR after an initial UTI.
• To analyze the rate of recurrent UTIs in patients receiving prophylaxis.
• To identify the pathogens involved in UTI recurrences.

Main Methods:

• Retrospective review of pediatric patients diagnosed with VUR.
• Analysis of patients who received antibiotic prophylaxis post-index UTI.
• Comparison of recurrent UTI rates between patients with and without urologic anomalies.
• Identification of causative organisms in recurrent UTIs.

Main Results:

• A significant rate of recurrent UTIs was observed in children on antibiotic prophylaxis for VUR.
• Recurrent UTIs occurred in 57% of patients with urologic anomalies and 33% without.
• Multidrug-resistant organisms were responsible for 25% of first UTI recurrences.

Conclusions:

• Antibiotic prophylaxis for VUR in children may have limited efficacy in preventing recurrent UTIs.
• The emergence of multidrug-resistant organisms is a concern in this patient population.
• Further research is needed to optimize management strategies for pediatric VUR.
