Plain English Summary
Background and study aims
Atopic dermatitis (AD) is an inflammatory skin disease affecting both children and adults. ‘Atopic’ means that the skin can react readily to environmental irritants and allergens. Over the past three decades the prevalence of atopic dermatitis has doubled or tripled in industrialised countries with some 15-20% of children and 2-10% of adults being affected. Its peak prevalence is highest in school-aged children and persists after puberty in up to 50% of children affected. Three main existing treatments, all with potential concerns, are traditionally prescribed in the treatment of AD including: topical corticosteroids (TCS), emollients and systemic treatments. TCS and emollients remain the mainstay of AD treatment. All the above treatments have side effects and researchers are yet to find a treatment that can be used long term without potential concerns. Therefore, the aim of this study is to assess whether merino wool has the ability to help prevent dermatitis from getting worse as a additional treatment option for patients with AD.
Who can participate?
Patients aged 6 to 25 with AD
What does the study involve?
Participants wear normal clothes for 5 weeks, wear Superfine Marino Wool Base Layer Garments (garments worn directly against the skin) for 5 weeks, then wear normal clothes for 5 weeks. Severity of AD is assessed during the three periods.
What are the possible benefits and risks of participating?
There may be no benefit in participating in this study, but these garments could improve the symptoms of AD. Discomfort may be minimized by a reduction in itchiness and redness, which should result in a decreased use and reliance on creams and ointments. There is however no guarantee that this will happen. The information collected in this study will help researchers to learn more about the relationship between AD patients and their clothing, in particular merino wool. Female participants who become pregnant during the study need to inform the study staff and be taken off the study. There are no safety concerns associated with wearing wool garments whilst pregnant. This is done because pregnancy can in a small percentage of females change the inflammatory course of dermatitis in either a positive or a negative way, and this may affect the study outcome.

A randomized, blinded, clinical trial assessing the efficacy of superfine merino wool base layer garments (SMWBG) in children with Atopic Dermatitis (AD) measuring SCORAD, EASI, POEM and DSA scores
Hypothesis (H)1: The fabric characteristics of Superfine Marino Wool Base Layer Garments (SMWBG) will be well tolerated by participants with AD.
H2: When SMWBG are worn by children and young adults they will experience a reduction in their AD symptoms and signs.

A with-garment intervention phase (IP) where participants wore Superfine Marino Wool Base Layer Garments [SMWBG] for 5 weeks, was compared with pre-garment IP and post-garment IP where participant's normal clothing was worn.
This study assessed the tolerability and potential therapeutic effect of superfine merino wool base layer garments (SMWBG) (garments worn directly against the skin) in children and young adults with atopic dermatitis (AD). We assessed the severity of AD looking at SCORAD1, EASI2, POEM3 and DSA4.
Primary outcome measure
The tolerability of superfine Merino wool base layer garments measured using SCORing Atopic Dermatitis (SCORAD), (Eczema Area and Severity Index), Dermatitis Severity Assessment (DSA), and Patient Orientated Eczema Measure (POEM), during the Pre-Garment intervention Phase (5 week period with 3 visits scheduled including baseline scores), the With-Garment intervention Phase (5 week period with 2 visits scheduled), and the Post-Garment intervention Phase (5 week period with 2 visits scheduled)
Secondary outcome measures
Quality of life, measured using Dermatology Life Quality Index (DLQI), Childrens Dermatology Life Quality Index (CDLQI), Patient Orientated Eczema Measure (POEM), during the Pre-Garment intervention Phase (5 week period with 3 visits scheduled including baseline scores), the With-Garment intervention Phase (5 week period with 2 visits scheduled), and the Post-Garment intervention Phase (5 week period with 2 visits scheduled)
