Is this trial a fit for you?
✓Likely a good fit
Adults (18 years and older) with a diagnosis of atopic dermatitis for more than six months who can complete questionnaires and are not on long-term systemic therapy are ideal candidates.
✕Probably not a fit
Children, patients currently receiving systemic treatments for a month or longer, those under legal protection, or anyone unable to complete questionnaires are unlikely to benefit from participating.

What this trial studies
This observational study will enroll adults with atopic dermatitis diagnosed for at least six months to measure the frequency of alloknesia and its impact on daily life. Participants will complete standardized questionnaires and undergo a clinical examination at participating French hospitals to document symptoms and quality-of-life consequences. People on prolonged systemic treatment or unable to complete questionnaires are excluded. Collected data will be used to describe prevalence and burden of alloknesia across the study sites.
Why it matters
Potential benefit: If successful, the results could help clinicians recognize and address touch-triggered itching, leading to better symptom management and improved quality of life for affected patients.
How similar studies have gone: This is a novel effort because the epidemiology and burden of alloknesia in chronic itch have not been previously studied.
