Filter by:This 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).
This case control study aims to determine whether spontaneous coronary artery dissection (SCAD) is associated with autoimmune diseases and to update the incidence of SCAD in a population-based cohort.
This is a randomized, controlled, open, three-armed, multi-centre study designed to compare the effects of dual-release hydrocortisone preparations versus conventional glucocorticoid therapy on anthropometric parameters, metabolic syndrome, infectious, immunological profile, cardiovascular system, bone mass and quality of life in patients affected by primary or secondary adrenal insufficiency.
The 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 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.
Patients with adrenal insufficiency also exhibit an adrenomedullary dysfunction. Furthermore, patients who suffer from both, adrenal insufficiency and type I diabetes more frequently report hypoglycemia, particularly after strenuous activities. The study investigates the counter regulatory hormonal response to physical stress and the impact on cognitive function in subjects with and without Addison's disease, type I diabetes and healthy subjects.
Patients 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.
Addison's disease is a rare disease, wherein the adrenals can not produce sufficient steroid hormones (cortisol and aldosterone). Patients with Addison's disease report impaired subjective health status, and they have increased all-cause mortality. Conventional therapy is by oral replacement of glucocorticoid and mineralocorticoid hormones, but this strategy imperfectly mimic the diurnal cortisol variations, and render the patients both over- and under-treated. Anecdotally, some patients with adrenal insufficiency may benefit from the use of various nutritional compounds. We hypothesised that liquorice and grapefruit altered the metabolism and absorption of cortisone acetate.
Addison's disease is a rare condition which in most cases is caused by autoimmune destruction of the adrenals, leading to deficiency of cortisol, aldosterone and adrenal androgens. Unrecognized the disease is life threatening, but with proper treatment patients can live near normal lives. The conventional glucocorticoid replacement therapy renders the cortisol levels unphysiological, which may cause symptoms and long-term complications. Glucocorticoid replacement therapy is technically feasible by continuous subcutaneous hydrocortisone infusion (CSHI), and can mimic the normal diurnal cortisol rhythm. This study aims to further evaluate CSHI treatment in terms of metabolic effects, effects on health-related quality-of-life and sleep in an 8 months randomised open label clinical trial with crossover design.
Suppression of the adrenal function is a common, potentially dangerous and unpredictable consequence of short term high dose glucocorticoid treatment. Identification of patients at risk would be of high clinical importance. The investigators hypothesized that the dexamethasone-suppression-test predicts the subsequent development of corticosteroid induced adrenal insufficiency.
