Study Details
Study Description
Brief Summary
The investigators studied whether scalp hair cortisol and testosterone levels differed between sarcoidosis patients both with and without fatigue and healthy controls.

Detailed Description
Rationale: Fatigue is a common symptom in patients with sarcoidosis and has great impact on quality of life. Several aspects in the pathogenesis of sarcoidosis and co-morbidities accompanying sarcoidosis could contribute to fatigue. However, until now the etiology of fatigue in sarcoidosis is unknown. Measurements of steroid hormones in scalp hair could possibly be directional in elucidating the underlying mechanism and could also be used as a screening and follow up tool in interventional studies.
Objective: A pilot to investigate whether cortisol and testosterone levels measured in hair differ between patients with sarcoidosis related fatigue, sarcoidosis patients without fatigue and healthy subjects.
Study design: A prospective observational study, using hair samples of sarcoidosis patients with and without fatigue, compared to an already existing age matched healthy control group.
Study population: Adult sarcoidosis patients at the outpatient clinic of the pulmonary department of the Erasmus MC, Rotterdam Main study parameters/endpoints: Cortisol and testosterone levels in scalp hair, correlation with Fatigue Assessment Scale.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Sarcoidosis - fatigued Men and women with sarcoidosis and a score of ≥ 22 on the Fatigue Assessment Scale. A small hair sample will be cut and the participants will be asked to complete questionnaires on fatigue, anxiety, depression, stress and quality of life. |
Other: Determination of scalp hair steroids
|
| Sarcoidosis - non-fatigued Men and women with sarcoidosis and a score of < 22 on the Fatigue Assessment Scale. A small hair sample will be cut and the participants will be asked to complete questionnaires on fatigue, anxiety, depression, stress and quality of life. |
Other: Determination of scalp hair steroids
|
| Healthy controls Hair steroid values of a previously collected normal values study in adults will be used as healthy controls |
Other: Determination of scalp hair steroids
