Addison's disease is a condition that leads to a reduction in production of steroid hormones from the adrenal glands. These hormones, particularly cortisol have many important roles in the body, one of which is increasing blood sugar. These steroids will be replaced with tablets but fails to mimic the normal increase in natural cortisol levels which increase from around 2am in the early morning. Furthermore, steroid tablets have been associated with stopping patients from going to sleep. Patients with Addison's disease on treatment still complain of excessive fatigue and have an increased risk of death from blood vessel diseases. Some case reports have shown some patients with Addison's disease to have low blood sugars overnight. To investigate the possible causes of fatigue in Addison's disease by examining sugar levels and sleep patterns of our patients. Blood clotting will also be looked at as a potential mechanism for the unexplained increase in blood vessel diseases. To examine sugar levels a small probe will be attached to the upper arm which the patients will wear for 14 days to measure blood glucose very regularly and is painless. Additionally the patients will wear a watch that monitors sleep, movement, and light. A single blood sample will be taken to measure vascular risk markers and how the blood clots. After wearing the monitors the subjects will complete questionnaires assessing quality of life. Healthy individuals will be recruited to undergo the same monitoring to act as a control group. The data data obtained between Addison's disease and healthy subjects will be compared. The scores from the questionnaires will be compared to the glucose and sleep readings to ascertain if there is a link between low blood sugars or sleep disturbance and their quality of life to determine if any physical abnormalities translate in to the poor quality of life.
The study will be looking at the cortisol profiles of hypocortisolaemic patients following 100mg injections of two hydrocortisone preparations (Solu-Cortef® & Hydrocortisone 100mg/ml). The investigators plan to use two methods of intramuscular injection to administer the preparations, one using a 1inch orange needle into the deltoid muscle and the other using a 1.25inch blue needle into the thigh muscle.
This is a multicentric, prospective, intervention study on circadian genes expression in peripheral blood mononuclear cells as biomarkers of circadian rhythm derangement in patients affected by alterations of endogenous glucocorticoids secretion (Cushing's Syndrome during active phase, treatment and under remission and newly or on established glucocorticoid replacement therapy adrenal insufficiency)
DOSCORT is a 2-dose, cross-over study primarily aiming to identify and validate novel biological markers (biomarkers) of glucocorticoid effect in the human body. Patients with Addison´s disease, primary adrenal insufficiency, with life-long glucocorticoid replacement therapy will undergo 2 treatment periods where their usual hydrocortisone treatment will be replaced with betamethasone in physiological and supra physiological doses. Blood, saliva, urine, health related Quality-of-life self-assessment forms, measurements of physical activity and sleep quality will be collected from both treatment periods.
The aim of this study is to compare the effects of tablet treatment, circadian and combined circadian and ultradian subcutaneous hydrocortisone infusion on steroid metabolism and tissue responses to therapy.
CoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, individuals and researchers to help in the advancement of research in over 7,000 rare diseases. The registry is free for patients to enroll and researchers to access. Visit sanfordresearch.org/CoRDS to enroll.
