About this study
Official title: Evaluation of the Muscular and Cutaneous Sodium Storage by 23Na Magnetic Resonance Imaging in Patients With Chronic Adrenal Insufficiency Compared to Healthy Subjects
This study investigates the sodium content in the calf muscle and the skin obtained via 23Na-magnetic resonance imaging in patients with chronic adrenal insufficiency compared to healthy controls.
Read the detailed description
Patients with chronic adrenal insufficiency depend on lifelong glucocorticoid and mineralocorticoid replacement therapy. Monitoring is based on clinical and laboratory parameters reflecting hemodynamic stability, electrolyte status and plasma renin concentration. Reduced subjective well-being is however often described by these patients in absence of clinical or laboratory abnormalities and is thus a strong indicator of the gap between the concept of adequate hormone substitution and patients' requirements. This study investigates the sodium content in the calf muscle and the skin obtained via 23Na-magnetic resonance imaging (MRI) in patients with chronic adrenal insufficiency compared to age-, sex- and BMI- matched healthy controls. The aim of the study is to evaluate the potential role of 23Na-MRI for monitoring of hormone replacement by investigating tissue sodium concentrations in patients with adrenal insufficiency.

What is being measured
The primary outcome is the main question the study is designed to answer.
Muscle sodium content
Assessment of the sodium content of the calf muscle. Relative sodium signal intensities were calculated as ratio of tissue sodium intensity and the intensity of a vial containing a concentration of 100mmol/l.
Measured: 6 months
Skin sodium content
Assessment of the sodium content of the calf skin. Relative sodium signal intensities were calculated as ratio of tissue sodium intensity and the intensity of a vial containing a concentration of 100mmol/l.
Measured: 6 months

Where is the study taking place?
The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Muscle sodium content (time frame: 6 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03505775, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Apr 2018; AzTrials last refreshed its copy on 7 Nov 2026.
