The Impact of Dietary Salt on the Severity of Eczema

Source: ClinicalTrials.gov · Last updated 10 Sept 2026

Brief summary (registry, in English)

The goal of this clinical trial is to evaluate the feasibility of low-sodium diet to improve eczema severity. The main questions it aims to answer are: * Does a low-sodium diet improve eczema severity? * How does a low-sodium diet impact skin sodium concentration? * Is skin sodium concentration associated with eczema severity? Researchers will ask all participant to follow a low-sodium diet, then compare sodium tablets to a placebo (a look-alike substance that contains no drug) to specifically examine the impact of altering sodium intake. Participants will: * Follow a low-salt diet for the duration of the 24-week study * Take sodium chloride tablets every day for 5 weeks followed by a placebo every day for 5 weeks after a 2-week washout period, or vice versa * Complete up to 4 virtual check-in visits * Visit the clinic 4 times to answer questionnaires, provide bio samples, complete dietary recalls, and undergo non-contrast sodium MRI

What you commit to

  • Study type: Interventional · Phase 4
  • Planned participants: 40
  • From Aug 2026 to the primary completion date, Mar 2028
  • 2 sites in 1 country
  • Visits and tests: ask the trial team, the registry does not list them

Built from the registry fields of ClinicalTrials.gov. It describes the study, not your situation.

Who cannot take part

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.

Prior treatment

  • Antibiotic or immunomodulatory medications within the last month

Other illness

  • Contraindications to MRI (such as cardiac pacemakers, claustrophobia, non-compatible intracranial vascular clips, IUDs, or other implants)
  • A cardiac event in the past 6 months

Lab values

  • Medications that influence sodium excretion (e.g., diuretics or SGLT2 inhibitors)
  • Contraindications to sodium tablets
    • (Topical medications used exclusively on the head/neck or hands/feet (e.g., antifungal nail treatment, antidandruff shampoo, acne cleansers) are acceptable. Topical and systemic eczema treatments are acceptable if the participant has been on a stable dose for at least 2 months and still meets the severity entry criteria. Patients on dupilumab will not be excluded if they have been on dupilumab for at least two months and still meet the disease severity inclusion criteria.)

Other

  • Impaired function of the liver or kidney (glomerular filtration rate \<60 mL/min)

Who the study is looking for

  • Participants ages 18 years
  • Willing and able to undergo non-contrast MRI.

Age in the registry: 18 years to - · Sex: All · Accepts healthy volunteers
