Sodium in the Skin and Atopic Dermatitis
(SIS-AD)
What this study is about
The goal of this observational study is to understand factors associated with skin sodium storage in healthy adults and people with atopic dermatitis ages 50 and above. The study is designed to test whether diet and skin barrier function are associated with skin sodium concentration and whether skin sodium concentration is linked to atopic dermatitis and immune profiles over time.
View original scientific description
The goal of this observational study is to understand factors associated with skin sodium storage in healthy adults and people with atopic dermatitis ages 50 and above. The study is designed to test whether diet and skin barrier function are associated with skin sodium concentration and whether skin sodium concentration is linked to atopic dermatitis and immune profiles over time. Participants will be asked to complete questionnaires, provide bio samples, and undergo non-contrast sodium MRI at 2-3 time points over 3-24 months.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
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.)

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
