Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants in the treatment arm will be asked to bathe in dilute bleach baths everyday for 1 week, then 3 times a week for 23 weeks. Participants will continue standard treatments for managing eczema.
Standard treatments for managing eczema include bathing daily with an emollient (other than the study emollient) added, application of moisturiser at least twice a day, the use of topical corticosteriods to eczema areas, and systemic antibiotics and wet dressings as required.

Outcomes
Primary outcome [1] 257987 0
Severity of eczema will be assessed by a blinded outcome assessor using the SCORing of Atopic Eczema (SCORAD) index.
Timepoint [1] 257987 0
Initial visit, 4 weeks, 12 weeks, 24 weeks.
Secondary outcome [1] 263541 0
Eradication of staphylococcal aureus will assessed by taking bacterial cultures and culture sensitivities from skin swabs of the nose, axilla and worst eczematous lesion. Eradication will be defined as no growth in 48 hours.
Timepoint [1] 263541 0
Initial visit, 4 weeks, 12 weeks, 24 weeks
Secondary outcome [2] 263542 0
Use of systemic antibiotics will be assessed by asking the participant/caregiver the number of completed courses of systemic antibiotics that were taken over the study period.
Timepoint [2] 263542 0
4 weeks, 12 weeks, 24 weeks
Secondary outcome [3] 263543 0
Tolerability of bleach baths will be assed by documenting the incidence of adverese events of interest to the dilute bleach baths. Reports will be rated by asking participants/caregivers to rate the level of stinging using a 5-point scale.

Summary
Brief summary
Eczema is a skin condition which affects the lives of many children and their families. Skin infections are common in people with eczema and can often make the eczema worse. The skin of people with eczema often contains high numbers of bacteria called Staphylococcus aureus. Lots of eczema treatments have been developed to reduce Staphylococcus aureus however it is not clear how well these treatments work.
Household bleach has been safely used for many years to help treat infected wounds after surgery. Recently it has been recommended for people with eczema to help reduce Staphylococcus aureus. Although it is being recommended for people with eczema there is little long-term evidence to show if household bleach is effective in improving eczema.
We want to see if there is an improvement in eczema in children who add a small amount of bleach solution to their bath. We will compare them to a group of children who add bath oil to their bath. The results of this project may influence the care of eczema in the future.
We hope 74 children who have moderate to severe eczema will take part in this project. Thirty-seven children will be asked to add a small amount of bleach solution to their bath and the other 37 children will be asked to add bath oil to their bath. The project will run for 6 months. The project will measure the severity of eczema before and after using the bleach solution or bath oil.
