Filter by:The purpose of this study is to determine whether patients with Hashimoto thyroiditis and impaired well-being may have a partial secondary adrenocortical insufficiency.
The extend of steroid biosynthesis and action is mainly dependent on underlying genetic polymorphisms and gene mutations. These sequence variations in multiple genes involved in steroid biosynthesis and action cause different diseases (for example congenital adrenal hyperplasia or disorders of sex development). In addition, sequence variations in several other genes may influence the severity of a genetically caused disease of steroid biosynthesis or action. By this, the differences in an observed phenotype may be explained. Within the study all genes necessary for adrenal and gonadal steroid biosynthesis and several genes which are known to influence the action of steroid hormones will be analysed in patients with congenital disorders of adrenal and gonadal steroid biosynthesis, disorders of steroid action and disorders of sex development. The primary aim is to set up a correlation of the disease phenotype with the different genotypes detected.
DHEA is an adrenal deriven androgen precourser. The impact of DHEA substitution therapy in adrenal failure is unknown as well as the physiologically effects of DHEA is unknown. Effects of physiologically DHEA substitution is investigated in the model of female adrenal failure.
Trauma patients are at increased risk for adrenal function insufficiency. A commonly used agent for rapid sequence intubation (RSI) is known to decrease adrenal function. We want to determine the incidence of adrenocortical insufficiency and its significance during the first 24 hours of resuscitation following RSI in trauma patients.
The purpose of this survey is to assess patients with chronic primary or secondary adrenal failure regarding subjective health status, incidence and causes of adrenal crisis, hormone replacement regimens and concomitant endocrine or non endocrine disease.
The purpose of this study is to determine if the combination of hydrocortisone plus fludrocortisone is more efficacious than hydrocortisone alone in treating adrenal insufficiency in severe sepsis.
Patients with newly diagnosed lung cancer may have hypofunction of the adrenal cortex either from tumour metastasis or other mechanisms. Since lung cancer patient may have to undergo stressful investigation and treatments, undetected hypofunction of the adrenal cortex may be hazardous. Knowledge of the size of the problem may help determine whether routine check is warranted.
The purpose of this pilot study is to (1) examine the changes in gene expression in patients who suffer from severe sepsis and whose shock (inadequate oxygen delivery to vital organs) state does not respond to fluid and vasopressor administration, (2) to show that our sampling method of isolating RNA provides reliable and consistent data, (3) provide a basis for future gene expression studies in critically ill patients
An appropriate hypothalamic-pituitary-adrenal (HPA) axis response is required to survive critical illness. Primary adrenal insufficiency, relative adrenal insufficiency, tissue resistance to glucocorticoids, ACTH deficiency and immune-mediated inhibition of the HPA axis may impair the secretion or action of glucocorticoids in critically ill patients. Adrenal insufficiency is estimated to occur in up to 77% of critically ill patients, but currently, there is no consensus on the diagnostic criteria for adrenal insufficiency in this setting, and standard testing does not discriminate among the aforementioned factors. We will study the incidence and natural history of adrenal insufficiency in critically ill patients to further define adrenal insufficiency and provide data to develop diagnostic tests. Clinical features and outcomes will be correlated with laboratory measurements of hormones, cytokines and glucocorticoid action. Healthy volunteers will undergo cortrosyn tests with measurement of free cortisol levels to develop a normative range for this endpoint. <TAB> Previous glucocorticoid use, if prolonged and supraphysiologic, also inhibits the HPA and can result in adrenal insufficiency. Patients with short intermittent courses of glucocorticoid administration have not been studied well, and may also be at risk. To gain further information about this group, patients receiving pulse glucocorticoid doses as part of bone marrow transplant regimens at the Clinical Center will also be studied. ...
This study will evaluate patients with a variety of endocrine disorders in order to 1) learn more about conditions that affect the endocrine glands (glands that secrete hormones) and 2) to train physicians in endocrinology. Patients of all ages with endocrine-related conditions may be eligible for evaluation under this protocol. Those enrolled may be required to provide blood, saliva, urine or stool samples, and to undergo ultrasound examination of the thyroid gland, ovaries or testes, adrenal glands or other parts of the body. Laboratory or X-ray studies may be done for diagnostic or treatment purposes. In some cases, patients will receive medical or surgical treatment for their disorder. Patients and family members of patients with a hereditary disorder may be asked to provide a blood sample for genetic analysis.
