Clinical Study on Circadian Genes Dysregulation in Patients With Glucocorticoid Disorders
Cushing SyndromeAdrenal Insufficiency2 moreThis 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)
Chronocort Versus Plenadren Replacement Therapy in Adults With Adrenal Insufficiency
Primary Adrenal InsufficiencyThis study is a double-blind, double-dummy, two-way cross-over, randomised, Phase II study to be conducted at approximately 6 investigational sites in 2 countries. The study will compare the efficacy, safety and tolerability of twice daily Chronocort, a modified-release hydrocortisone, with once daily Plenadren, a modified-release hydrocortisone, over a treatment period of up to 2 months in participants aged 18 years and over, diagnosed with primary Adrenal Insufficiency (AI).
The Effects of Two Brands of Hydrocortisone Injected Intramuscularly Into Deltoid and Thigh Muscles...
Addison's DiseaseThe 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.
Screening and Stimulation Testing for Residual Secretion of Adrenal Steroid Hormones in Autoimmune...
Primary Adrenal InsufficiencyIn autoimmune adrenal insufficiency, or Addison's disease (AD), the immune system attacks the adrenal cortex. As a result, the adrenal cells producing hormones such as cortisol and aldosterone are destroyed, leaving the body with insufficient levels to meet its needs. The common perception is that upon diagnosis of Addison's disease, basically all adrenal hormone production has ceased. There have, however, been found a few individuals who preserve some residual secretion of cortisol even years after diagnosis. The objectives of this study is to find out how common it is, and to explore if residual function have impact on patient outcome. That is, do patients with and without residual function differ when it comes to quality of life, working ability, medication dosages, and risk of adrenal crisis?
Does Relative Hypoglycaemia &/or Sleep Disturbance Contribute to the Lethargy Observed in Addison's...
Addison DiseaseAddison'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.
Rare Disease Patient Registry & Natural History Study - Coordination of Rare Diseases at Sanford...
Rare DisordersUndiagnosed Disorders316 moreCoRDS, 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.
Biomarker(s) for Glucocorticoids
Addison DiseaseThe investigators have shown that patients with adrenal insufficiency (Addison's disease), a rare disorder, have doubled the expected mortality rate in Sweden despite Standard of Care glucocorticoid (GC) replacement. One % of the Swedish population are, however, receiving GCs for inflammatory diseases, but management is empirical and adjusted to underlying disease activity. The desired anti-inflammatory therapeutic effects cannot be differentiated from the adverse metabolic (osteoporosis, obesity, diabetes mellitus) and immunosuppressive side effects of GC. This frequently results in suboptimal GC therapy with adverse effects due to over-dosing or poor efficacy due to under-dosing. The primary aim is to identify a biomarker for the metabolic effects of GCs. Patients with Addison's disease completely lack endogenous GCs and can therefore be considered a human GC knock-out model. They can therefore be studied during near-physiological exposure and during GC starvation. This will uniquely allow a very clean biomarker identification model (using transcriptomics, proteomics and metabolomics). The secondary aim is to validate candidate biomarker(s) in a dose-response study using the same patient population. A biomarker of GC actions will make it possible to individualised therapy during pharmacological GC treatment. It would allow GC replacement to be monitored in Addison's disease and could become a specific diagnostic tool in patients with GC deficiency and excess (Cushings syndrome).
The Hypothalamic-Pituitary-Adrenal (HPA) Axis as an Effector System in Weight Regulation
ObesityAddison's DiseaseReplacing glucocorticoid in a dose dependent manner (including doses within the physiological range) to subjects with adrenal insufficiency will increase visceral fat accumulation independently of total fat mass.
Pharmacokinetics of Hydrocortisone After Subcutaneous Administration in Chronic Adrenal Insufficiency...
Primary Adrenal InsufficiencyPatients with chronic adrenal insufficiency need to adapt their hydrocortisone replacement dose in conditions of physical or psychological stress to prevent life threatening adrenal crisis. In cases of more severe impairment or unsecure gastrointestinal absorption (e.g. gastroenteritis, severe infectious disease), parenteral administration of the hydrocortisone dose is crucial. The study is conducted to offer patients the possibility to perform hydrocortisone self administration in emergency situations in a way of administration which is easy to perform and accepted by the patient. Therefore, pharmacokinetics and safety of subcutaneous hydrocortisone administration will be studied and compared to intramuscular administration.
