Supplemental hydrocortisone for adrenal insufficiency during stress

RESCUE - Effect of Supplemental Hydrocortisone During Stress in Prednisolone-induced Adrenal Insufficiency; A Multicentre, Randomised, Double Blinded, Placebo-controlled Clinical Trial on Health-related Quality of Life in Patients With Polymyalgia Rheumatica/Giant Cell Arteritis Receiving Ongoing Low-dose Prednisolone Treatment.

Phase 4 Interventional Rigshospitalet, Denmark · NCT05435781

This study is testing if adding hydrocortisone can help people with polymyalgia rheumatica or giant cell arteritis who have low adrenal function feel better during stressful times compared to a placebo.

What this trial studies

This clinical trial investigates the effects of supplemental hydrocortisone compared to a placebo in patients with polymyalgia rheumatica (PMR) or giant cell arteritis (GCA) who are experiencing glucocorticoid-induced adrenal insufficiency while on low-dose prednisolone. The study is double-blinded and randomized, focusing on health-related quality of life, particularly fatigue, during periods of mild to moderate stress. Participants will be monitored for their cortisol levels and will receive either hydrocortisone or placebo during stressful situations over a duration of six months. The trial also includes a reference group of patients with normal adrenal function for comparison.

Who should consider this trial

Good fit: Ideal candidates are postmenopausal women and men aged 50 and older with PMR or GCA on low-dose prednisolone treatment.

Not a fit: Patients with known primary or secondary adrenal insufficiency or severe comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the management of adrenal insufficiency in patients undergoing treatment for PMR and GCA, enhancing their quality of life during stress.

How similar studies have performed: Other studies have shown promising results with similar approaches in managing adrenal insufficiency, suggesting potential for success in this trial.
