Long-term observation of atopic dermatitis and related allergic conditions

Prospective Longitudinal Observational Research Study to Investigate the Remission of Atopic Dermatitis and Associated Allergic Diseases

Observational University of Zurich · NCT04240522

This project will collect medical and lab data over time to see which genetic, immune, environmental, and microbial factors relate to the course or remission of atopic dermatitis and other atopic diseases in people of all ages.

What this trial studies

This is a prospective, longitudinal observational cohort that will enroll people with atopic dermatitis and other atopic diseases, plus healthy controls, across ages 0–85. Participants will remain on their medically indicated therapies while clinicians collect standardized clinical data, biosamples, and laboratory measurements over time. The study aims to link endogenous factors (genetic, immunological, molecular) and exogenous factors (environmental, socioeconomic, microbial) to disease course, remission, and the development of related atopic conditions. Collected data will be used to define patient subgroups (endotypes) and search for biomarkers that predict individual clinical trajectories.

Who should consider this trial

Good fit: Ideal candidates are people aged 0–85 with a diagnosis of atopic dermatitis or another atopic disease, and healthy volunteers without allergic disease, who can provide informed consent (or have a guardian provide consent).

Not a fit: People seeking immediate experimental therapies or direct clinical benefit from the protocol are unlikely to gain treatment benefit since this is an observational data-collection project, and those unable to attend follow-up visits or provide samples will not benefit from the study's aims.

Why it matters

Potential benefit: If successful, the findings could enable earlier prediction of flares or remission and support more personalized prevention and treatment strategies for atopic diseases.

How similar studies have performed: Previous longitudinal cohorts have identified some genetic and immune markers linked to atopic march and endotypes, but results have been only partially reproducible and larger, multi-factor studies are still needed.

Inclusion Criteria:

* Age 0 - 85 years
* Diagnosis of AD and/or another disease of the atopic group (i.e. allergic rhinitis, allergic asthma, food allergy)

* No diagnosis or history of allergic disease
* The inclusion of patients in this study is independent from the current therapy. During the study all patients will be kept on a therapy that is medically indicated

Written consent will be obtained after detailed information of the study was given to the participant.
