Study of adrenal nodules and how cortisol levels respond to a test
Part of Hormones & metabolism clinical trials.
This study looks at adrenal nodules found on a CT scan and checks whether your cortisol levels stay high after a medication test. It may help researchers understand what causes abnormal cortisol production and how often it happens in people with adrenal growths.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have adrenal nodules seen on CT, with the largest size at least 10 mm
- Your cortisol level is high after the 1 mg dexamethasone suppression test (1mg-DST)
- You do NOT have primary aldosteronism, adrenal pheochromocytoma, adrenal cancer spread, or congenital adrenal hyperplasia
- You do NOT have certain nerve/adrenal tumor types (like paraganglioma or schwannoma) and there is no unclear diagnosis
- You are not currently pregnant and you do not have serious illnesses that could affect hormone control (like major liver or kidney failure, severe infection)

Other trials that look related to this one.
This trial is testing a new method (using a blood test that measures steroid hormones) to better diagnose whether adrenal nodules are causing mild hormone problems. It may help doctors decide if you need treatment or just monitoring.
This study looks at how your body's natural steroid rhythms change when you have adrenal nodules. It compares people with non-secreting nodules to those with a mild hormone excess (MACS) to see if there are differences in daily cortisol patterns.
This study tracks thinking and brain changes over time in people with adrenal findings that produce too much cortisol (a stress hormone) on their own. It may help doctors understand how different treatments or watchful waiting affect the brain and cognition.
This study looks for a mild form of hormone overproduction (called autonomous cortisol secretion) in people who have a benign growth on their adrenal gland. You will undergo a blood test to measure how well your body suppresses cortisol after taking a single dose of dexamethasone.
This study follows adults with a new adrenal diagnosis to learn how adrenal diseases behave over time. It may help doctors better understand these conditions and improve future care.
This study looks at how often adrenal insufficiency happens after surgery for primary aldosteronism, especially in patients who also have an overproduction of cortisol. It helps doctors understand if extra hormone support is needed after surgery.
