Monitoring cortisol levels in different body fluids

Real-time Monitoring of Cortisol - Comparison of Cortisol Levels in Four Biological Fluids

Observational Centre Hospitalier Universitaire Vaudois · NCT06008184

This study is testing a new way to measure cortisol levels in sweat, saliva, interstitial fluid, and blood to see how they compare and improve monitoring for adrenal-related conditions.

What this trial studies

This observational study aims to compare cortisol levels in four biological fluids: sweat, saliva, interstitial fluid, and blood. By utilizing a non-invasive and ambulatory method, the study seeks to validate a continuous cortisol measurement device currently under development. Participants will undergo 24-hour sampling of these fluids to assess the correlation of cortisol levels across different mediums. The findings could enhance our understanding of cortisol secretion patterns and improve monitoring methods for conditions related to adrenal function.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy individuals aged 18 to 30 with a normal BMI and stable weight.

Not a fit: Patients who are pregnant, breastfeeding, or have any medical issues or treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate and non-invasive monitoring of cortisol levels for patients with adrenal disorders.

How similar studies have performed: While the approach of real-time cortisol monitoring is innovative, similar studies have not been extensively documented, indicating this may be a novel exploration.
