Investigating the effects of steroid use on chronic rhinosinusitis and bone density

Adherence in Global Airways - the Relationship Between Steroid Intake and the Impact on the Endocrine Axis, Bone Density, and Structure in Patients With Chronic Sinusitis and Asthma

Observational Rigshospitalet, Denmark · NCT05843019

This study is testing how long-term steroid use affects people with chronic rhinosinusitis and asthma, focusing on their cortisol levels and bone density.

What this trial studies

This observational study aims to explore the relationship between long-term systemic steroid use and cortisol production in patients with chronic rhinosinusitis (CRS) and asthma. It will assess how steroid intake correlates with baseline cortisol levels and the body's response to ACTH, as well as the impact on bone density through DEXA scans. The study will include patients diagnosed with CRS, both with and without asthma, to provide a comprehensive understanding of steroid effects on health outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 diagnosed with chronic rhinosinusitis, with or without asthma, who have a history of systemic steroid use.

Not a fit: Patients who have never taken systemic steroids or those with severe psychiatric comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help identify the risks associated with steroid use in patients with chronic respiratory conditions, leading to better management strategies.

How similar studies have performed: While the specific approach of this study may be novel, previous studies have indicated potential risks associated with long-term steroid use in similar patient populations.
