Outcomes

Primary Outcome Measures

Recurrent Febrile or Symptomatic Urinary Tract Infection During 2-year Follow-up

Secondary Outcome Measures

Outcome Renal Scarring
Renal scarring was defined as a decreased uptake of tracer that was associated with loss of contours or the presence of cortical thinning. Outcome dimercaptosuccinic acid (DMSA) scan was performed at 2 years after enrollment or 3-4 months after the child had met treatment failure criteria.
Severe Renal Scarring on Outcome Scan
Severe renal scarring was defined as scarring in more than 4 of 12 segments in at least one kidney or global atrophy characterized by diffusely scarred and shrunken kidney. Outcome DMSA scan performed at 2 years after enrollment or 3-4 months after the child had met treatment failure criteria.
New Renal Scarring on Outcome Scan
New renal scarring was defined as scarring on the outcome renal scan with technetium -99m-labeled dimercaptosuccinic acid that was not present at baseline. Outcome DMSA scan performed at 2 years after enrollment or 3-4 months after the child had met treatment failure criteria.
Treatment Failure Composite
Treatment failure was defined as the occurrence of two febrile urinary tract infections (UTIs), one febrile UTI and three symptomatic UTIs, four symptomatic UTIs, or new or worsening renal scarring on an interim scan (e.g,, the 12-month visit); renal scans from the 2-year visit are NOT considered in the treatment failure criteria.
Presence of E.Coli Resistant to Trimethoprim-Sulfamethoxazole (TMP-SMZ) (Based on Rectal Swab)
Recurrent Febrile or Symptomatic UTI With Resistant E. Coli
Recurrent Febrile or Symptomatic UTI With Any Resistant Pathogen

5. Study Description

Brief Summary
In this 2-year, multisite, randomized, placebo-controlled trial involving 607 children with vesicoureteral reflux that was diagnosed after a first or second febrile or symptomatic urinary tract infecton, we evaluated the efficacy of Trimethoprim-Sulfamethoxazole (TMP-SMZ) prophylaxis in preventing recurrences (primary outcome). Secondary outcomes were renal scarring, treatment failure (a composite of recurrences and scarring), and antimicrobial resistance.
Detailed Description
This multicenter, randomized, double-blind, placebo-controlled trial was 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 were randomly assigned to treatment for 2 years with daily antimicrobial prophylaxis (trimethoprim-sulfamethoxazole) or placebo. The study was designed to recruit 600 children (approximately 300 in each treatment group). The protocol encouraged prompt evaluation of children with UTI symptoms and early therapy of culture-proven UTIs. It was 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%. The primary analysis is intention-to-treat with missing outcome data analyzed as UTI. 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 were assessed periodically throughout the study.
