Filter by:Cortisol is essential for survival. The importance of cortisol response is most apparent in patients with partial or complete deficiency of glucocorticoids during stressful events such as illness or surgery.
The purpose of this study is to gather safety and effectiveness information about a new formulation of Hydrocortisone (Chronocort®) used to treat patients with a disease called congenital adrenal hyperplasia (CAH). Hydrocortisone is the man-made version of the hormone cortisol, which is released in the body following a regular daily pattern. The objective of the study is to measure the levels of hydrocortisone that are absorbed into the bloodstream once Chronocort® is taken and what affects it has on other hormones in the body. Since Chronocort® is anticipated to mimic the same release pattern of cortisol in the body, it is hoped that patients with CAH will be treated more effectively to manage their disease.
The pathophysiology of the adrenal insufficiency of patients with critical diseases remains unclear. In a prior exploratory study investigating patients with exacerbation of chronic obstructive pulmonary disease (COPD), the investigators demonstrated a highly significant correlation between the expression level of Defensin-alpha 4 (DEFA4) mRNA in blood and the adrenal function assessed via low-dose ACTH tests. The aim of this prospective study is to demonstrate that DEFA4 measured both at the mRNA level (RT-PCR) and at the protein level (Western blot/Elisa) is a reliable biomarker for the prediction of adrenal insufficiency in inflammatory lung diseases (patients with COPD and pneumonia).
As a post-approval requirement of the European Medicines Agency, this European patient post authorization safety study is an observational study being conducted to monitor the safety of long-term treatment with Plenadren and other glucocorticoid replacement therapies in routine clinical practice in patients with chronic adrenal insufficiency (primary or secondary).
The purpose of this study is to compare the efficacy and effects on the hypothalamus-pituitary-adrenal axis of a single intrabursal injection of two different types of corticosteroids (methylprednisolone and triamcinolone) in patients with calcific shoulder tendinopathy.
The aim of this study is to investigate whether a physiologically low hydrocortisone (HC) dose is better for cognition as compared to a physiologically high HC dose. In addition, quality of life, metabolic profile and somatosensation will be described in relation to HC dose.
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.
The diagnosis of secondary AI is vital to prevent catastrophic events in patients. An optimal test should have a very low margin of error with high sensitivity and specificity, be easy and safe to administer, and have distinct cut off values. Both 1 ug and 250 ug doses have their limitations. Based on our experience over the past six years, we hypothesize that 25 ug ACTH stimulation test may eliminate some of the shortcomings of the LDST (1 ug) and SDST (250 ug). This is supported by our preliminary data and the study by Oelkers et al, which looked at ACTH levels following various doses of cortrosyn injections. Therefore we propose a head to head comparison of 25 ug, 250 ug and 1 ug dose using ITT as gold standard.
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.
