1 The Role of Glucocorticoid Receptor SNPs in Receptor Function and Metabolic Disease

Background: - Glucocorticoids are primary stress response hormones released from the adrenal gland when an individual is under stress. Chronic or ongoing elevation of these hormones due to prolonged stress or medical treatments can have numerous harmful effects. Researchers are interested in learning more about how these hormones affect cell growth, development, and death. To study glucocorticoid hormones, researchers plan to use the medication dexamethasone, which affects the parts of cells that respond to glucocorticoid hormones. Objectives: - To study glucocorticoid stress hormones in healthy individuals before and after receiving dexamethasone. Eligibility: - Healthy individuals at least 18 years of age. - Participants must not be using certain medications that may affect the dexamethasone test, including hormonal contraception, steroid-based drugs, and some antidepressants. Design: - This study will require an initial screening visit and a second study visit. The visits are estimated to require about 1 to 2 hours of participation over a period of up to 14 days. - Participants will be screened at visit 1 with a full physical examination and medical history, and an initial blood sample for testing. - For visit 2, participants will be asked to abstain from all food and drinks except for water for 12 hours before the appointment, and will take one tablet of dexamethasone 9 hours before the appointment. - Participants will have a second blood sample taken during visit 2, and will receive a snack after the blood is drawn.

2 Observational Cohort Study on Difference in Glucocorticoid-induced Adrenal Insufficiency in Patients With Rheumatoid Arthritis Related to Different Sensitivity Polymorphisms in the Glucocorticoid Receptor Gene

Development of glucocorticoid (GC)-induced adrenal insufficiency is a serious adverse effect of GC treatment. It is today not possible to predict this adverse effect. The project aims at investigating a possible individual aspect, which may render subjects more or less sensitive to glucocorticoids, and thereby influence development of GC induced adrenal insufficiency. The hypothesis is that subjects with one or another of the polymorphisms in the GC receptor gene will either have increased or diminished GC sensitivity. This may be responsible for differences in development of GC induced adrenal insufficiency.

3 Prevalence of Adrenal Insufficiency in Kidney Transplanted Patients (NTx) in Glucocorticoid Treatment

The primary purpose of this study is to determine the prevalence of adrenal insufficiency in a population of patients with kidney transplants receiving low dose prednisone treatment. Development of glucocorticoid-induced adrenal insufficiency is a serious adverse effect to glucocorticoid treatment. The study includes a control group of patients with kidney failure currently treated in dialysis, who are not in glucocorticoid treatment. Individual genotyping is performed to determine the haplotype of glucocorticoid receptor polymorphisms: N363 S, BclI, ER23/23EK and 9β in all the patients with the purpose of investigating this as a risk factor for the development of adrenal insufficiency. The hypothesis is that subjects with one or another of the polymorphisms in the glucocorticoid receptor gene will either have increased or diminished glucocorticoid sensitivity. Using validated questionnaires assessing the quality of life and functional level of the patients enrolled in the study we aim to establish a link between functional level and biochemically proven adrenal insufficiency. Other secondary outcomes in the study includes bloodpressure, body composition, bone density, metabolic syndrome, inflammation and salivary cortisol profiles.
