What is being measured
The primary outcome is the main question the study is designed to answer.
Eczema Area and Severity Index (EASI)
Clinician-assessed measure of atopic dermatitis severity based on extent and severity of eczema signs; total score ranges from 0 to 72, with higher scores indicating more severe disease.
Measured: Baseline and follow-up visits every 6-12 months for up to 5 years.
Secondary outcomes (7)
SCORing Atopic Dermatitis (SCORAD)
Clinician-assessed measure of atopic dermatitis severity incorporating extent, intensity, and subjective symptoms; total score ranges from 0 to 103, with higher scores indicating more severe disease.
Measured: Baseline and follow-up visits every 6-12 months for up to 5 years.
Dermatology Life Quality Index (DLQI)
Patient-reported measure of dermatology-specific quality of life; total score ranges from 0 to 30, with higher scores indicating greater impairment.
Measured: Baseline and follow-up visits every 6-12 months for up to 5 years.
Patient-Oriented Eczema Measure (POEM)
Patient-reported measure of atopic dermatitis symptoms and disease burden; total score ranges from 0 to 28, with higher scores indicating more severe disease.
Measured: Baseline and follow-up visits every 6-12 months for up to 5 years.
Peak Pruritus Numerical Rating Scale (PP-NRS)
Patient-reported assessment of peak itch severity on a numerical rating scale from 0 (no itch) to 10 (worst imaginable itch).
Measured: Baseline and follow-up visits every 6-12 months for up to 5 years.
Physician Global Assessment (PGA)
Clinician-assessed global measure of atopic dermatitis severity on a scale from 0 (clear) to 4 (severe).
Measured: Baseline and follow-up visits every 6-12 months for up to 5 years.
Body Surface Area (BSA)
Percentage of total body surface area affected by atopic dermatitis, ranging from 0% to 100%.
Measured: Baseline and follow-up visits every 6-12 months for up to 5 years.
Patient-reported Numerical Rating Scale (NRS) for atopic dermatitis severity
Patient-reported assessment of overall atopic dermatitis severity on a numerical rating scale from 0 (no disease) to 10 (most severe disease imaginable).
Measured: Baseline and follow-up visits every 6-12 months for up to 5 years.

Questions about this trial
What is this clinical trial studying?
An observational study of Atopic Dermatitis (AD) and Atopic Dermatitis (Eczema), run by Julia Tatjana Maul at 1 site in Switzerland.

Where is the study taking place?
The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?

Eczema Area and Severity Index (EASI) (time frame: Baseline and follow-up visits every 6-12 months for up to 5 years.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
