This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early

Summary

This observational study investigates factors linked to sodium stored in the skin of healthy adults and people with atopic dermatitis (eczema) aged 50 and older. Researchers aim to see if diet and skin barrier function affect skin sodium levels, and whether those levels are tied to eczema severity and immune changes over time. Participants complete questionnaires, provide biological samples, and undergo non-contrast sodium MRI scans at two to three visits across three to 24 months.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Ages 50 years and above * Willing to undergo non-contrast MRI (e.g., no contraindications to MRI, such as cardiac pacemakers, non-compatible intracranial vascular clips or pregnancy). Exclusion Criteria: * History of autoimmune disease. * Cardiac events in the last six months. * Impaired function of the liver or kidneys (glomerular filtration rate \<60ml/min). * Current use of medications that influence sodium excretion (e.g. thiazide diuretics, SGLT2 inhibitors and spironolactone), and/or chemotherapy or antibiotic treatment. * Currently receiving phototherapy or taking systemic medications for atopic dermatitis including cyclosporine, methotrexate, or other broad immunosuppressive medications. (Patients on dupilumab will not be excluded if they have been on dupilumab for at least two months and still meet the criteria for severe disease.)
