The purpose of this study is to learn whether all children with vesicoureteral reflux (VUR) should be treated with antibiotics. The study will tell us if prophylactic antibiotic treatment prevents urinary tract infections and renal scarring in children with VUR.
This multicenter, randomized, double-blind, placebo-controlled trial is designed to determine whether daily antimicrobial prophylaxis is superior to placebo in preventing recurrence of urinary tract infection (UTI) in children with vesicoureteral reflux (VUR). Eligibility criteria are described elsewhere. Patients will be randomly assigned to treatment for 2 years with daily antimicrobial prophylaxis (trimethoprim-sulfamethoxazole) or placebo. The study is designed to recruit 600 children (approximately 300 in each treatment group) over a 24 month period. The protocol will encourage prompt evaluation of children with UTI symptoms and early therapy of culture-proven UTIs. It is expected that approximately 10% of children will have to discontinue study medication due to allergic reactions. Assuming a 20% placebo event rate and 10% non-compliance rate, the study has 83% power to detect an absolute 10% event rate in the antimicrobial prophylaxis group. If the placebo event rate is instead 25%, power is 97% to detect an absolute 10% event rate in the treated group, even if non-compliance is as high as 15%.
In addition to collecting follow-up data on urinary tract infections, renal scarring and antimicrobial resistance, quality of life, compliance, safety parameters, utilization of health resources, and change in VUR will be assessed periodically throughout the study.

Retrograde flow of urine from the URINARY BLADDER into the URETER. This is often due to incompetence of the vesicoureteral valve leading to ascending bacterial infection into the KIDNEY.
A pyrimidine inhibitor of dihydrofolate reductase, it is an antibacterial related to PYRIMETHAMINE. The interference with folic acid metabolism may cause a depression of hematopoiesis. It is potentiated by SULFONAMIDES and the TRIMETHOPRIM-SULFAMETHOXAZOLE COMBINATION is the form most often used. It is sometimes used alone as an antimalarial. TRIMETHOPRIM RESISTANCE has been reported.
