Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are children aged 2-5 with a confirmed diagnosis of atopic dermatitis and an Eczema Area and Severity Index of 2 or higher.

Probably not a fit

Patients with mild atopic dermatitis (EASI < 2), immune deficiencies, or other significant health conditions may not benefit from this study.

What this trial studies

This study investigates the impact of exposure to microbial diversity through sand play on children with atopic dermatitis. It aims to determine if playing in a sandbox can reduce eczema symptoms and alter immune responses by assessing various health indicators. Approximately 80 children aged 2-5 with atopic dermatitis will be recruited to participate in this interventional study, where they will be divided into groups receiving either a microbial intervention or a placebo. The study will measure changes in eczema severity, immune markers, and microbial communities.

Why it matters

Potential benefit: If successful, this study could provide a novel, natural approach to managing atopic dermatitis in children.

How similar studies have gone: Previous studies have suggested a link between microbial exposure and reduced atopic dermatitis symptoms, indicating potential success for this approach.
