Does Relative Hypoglycaemia &/or Sleep Disturbance Contribute to the Lethargy Observed in Addison's Disease

Observational The Leeds Teaching Hospitals NHS Trust · NCT05515055

This study looks at what might be causing fatigue in people with Addison's disease by checking their blood sugar levels and sleep patterns to see how these factors affect their overall health.

What this trial studies

This observational study aims to explore the potential factors contributing to fatigue in patients with Addison's disease, focusing on blood sugar levels and sleep disturbances. Patients with primary adrenal insufficiency will undergo blood tests to assess their glucose levels and sleep patterns, as well as evaluate blood clotting as a possible mechanism for increased cardiovascular risks. The study seeks to understand how current glucocorticoid replacement therapies may impact these factors and contribute to the overall health status of individuals with Addison's disease.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old diagnosed with Addison's disease, with or without type 1 diabetes.

Not a fit: Patients with significant kidney disease, active cancer, or those unable to provide valid consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved management strategies for fatigue in patients with Addison's disease.

How similar studies have performed: While there is limited research specifically targeting the fatigue in Addison's disease through this approach, studies on glucocorticoid replacement therapies have shown varying degrees of success in managing related symptoms.
