Corticosteroids for Children With Febrile Urinary Tract Infections (STARRS)

June 24, 2019 updated by: Nader Shaikh
In this study the investigators will determine whether corticosteroids given at the time of urinary tract infection help prevent permanent damage to the kidneys.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Because host inflammatory response is the final and most important step in the formation of renal scars, the use of anti-inflammatory agents may be the best strategy to reduce renal scarring. In animal studies, the use of corticosteroids has been shown to be effective in preventing post-pyelonephritic scarring. We will conduct a randomized, double-blind, placebo-controlled trial to determine the efficacy of 3 days of daily adjuvant dexamethasone on the incidence of renal scarring 4 to 6 months after a first febrile urinary tract infection (UTI). We hypothesize that the proportion of children with UTI who develop renal scarring will be lower among children who are treated with both dexamethasone and antibiotics as compared with children treated with antibiotics alone.

Phase

Phase

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

2 months to 6 years (Child)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The Distribution of Children With Renal Scarring at the Outcome Dimercaptosuccinic Acid (DMSA) Renal Scan
Time Frame: The outcome DMSA scan was 5-24 months from enrollment. The mean number of months was 6.1.
Renal scarring was defined as decreased uptake of tracer with or without loss of contours. Three radiologists independently reviewed for scarring all DMSA scans that were of adequate quality. For a given kidney, the presence or absence of scarring was the diagnosis endorsed by the majority of readers, i.e. 2 of 3. For a given child, if either kidney or both kidneys were diagnosed with scarring by the majority of readers, then the child was determined to have renal scarring.
The outcome DMSA scan was 5-24 months from enrollment. The mean number of months was 6.1.
The Distribution of Children With Severe Renal Scarring at the Outcome Dimercaptosuccinic Acid (DMSA) Renal Scan
Time Frame: The outcome DMSA scan was 5-24 months from enrollment. The mean number of months was 6.1.
Renal scarring was defined as decreased uptake of tracer with or without loss of contours. Scarring was assessed semi-quantitatively by dividing the renal cortex into 12 equal segments. Severe scarring was defined as greater than 4 affected renal segments or global atrophy, i.e. diffuse scarring or shrunken kidney. Three radiologists independently reviewed for scarring all DMSA scans that were of adequate quality. For a given kidney, the presence or absence of severe scarring was the diagnosis endorsed by the majority of readers, i.e. 2 of 3. For a given child, if either kidney or both kidneys were diagnosed with severe scarring by the majority of readers, then the child was determined to have severe renal scarring.
The outcome DMSA scan was 5-24 months from enrollment. The mean number of months was 6.1.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The Mean Proportion of Children With Renal Scarring at the Outcome Dimercaptosuccinic Acid (DMSA) Renal Scan Taken Across the 3 Radiologists
Time Frame: The outcome DMSA scan was 5-24 months from enrollment. The mean number of months was 6.1.
Renal scarring was defined as decreased uptake of tracer with or without loss of contours. Three radiologists independently reviewed for scarring all DMSA scans that were of adequate quality. For each radiologist, for each child, if either kidney or both kidneys were diagnosed with scarring, then the child was determined to have renal scarring. For each radiologist, the proportion of children with scarring in a given treatment group is the number of children diagnosed with scarring divided by the number of children in the treatment group. The mean proportion of children with scarring in a given treatment group is the average proportion taken across the 3 radiologists.
The outcome DMSA scan was 5-24 months from enrollment. The mean number of months was 6.1.
