Assessing adrenal function in patients with Addison's disease
Official title: Residual Adrenal Function in Addison's Disease
Run by Istituto Auxologico Italiano · NCT06309498 · Data updated 2026-11-12
This study is testing whether measuring a specific hormone can help doctors understand how well the adrenal glands are working in people with Addison's disease and if that can improve their treatment and quality of life.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are individuals diagnosed with autoimmune Addison's disease who can provide informed consent.
✕Probably not a fit
Patients currently taking drugs that affect the immune system or steroids other than hydrocortisone or cortisone acetate may not benefit from this study.

What this trial studies
This observational study aims to evaluate the role of 11-deoxycortisol as a surrogate marker for residual adrenal function in patients with autoimmune Addison's disease. It will involve measuring 11-deoxycortisol levels in recruited patients to determine if any residual endogenous corticosteroid production exists. The study seeks to understand the clinical significance of residual adrenal function, which may impact treatment needs and overall quality of life for patients. By identifying patients with residual function, the study could help tailor hormone replacement therapy more effectively.
Why it matters
Potential benefit: If successful, this study could lead to more personalized treatment plans for patients with Addison's disease, potentially reducing the need for hormone replacement therapy.
How similar studies have gone: While some studies have indicated the presence of residual adrenal function in a subset of Addison's patients, this specific approach using 11-deoxycortisol as a marker is novel and has not been extensively tested.
