Filter by:Replacing 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.
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 success of kidney transplantation is hampered by the shortage of organs. One attractive strategy is the use of kidneys from living donors. During the donor operation the kidney artery, kidney vein and ureter have to be interrupted as far as possible from the kidney to have sufficient length for the reconnection of these structures in the transplant operation. An adrenal gland is situated at the upper pole of each kidney. While the arterial supply is accomplished by many small vessels, the venous drainage is only through one vein. On the right side the adrenal vein empties directly into the inferior vena cava (the large vessel transporting blood from the lower body to the heart). In contrast, on the left side the adrenal vein empties into the kidney vein, which in turn drains to the inferior vana cava. Due to these anatomical differences a left-sided removal of a kidney always necessitates an interruption of the left adrenal vein, while a right-sided kidney removal does not. As the venous drainage of the left adrenal gland is closed during living kidney donation, the gland is most likely functionally impaired. This can be compared to a right-sided kidney donation, where the adrenal vein is left intact. These comparisons are performed by adrenal function tests before, one week after and one month after kidney donation. These function tests consist of blood values drawn after stimulation with a hormone drug.
OBJECTIVES: I. Determine the efficacy of dehydroepiandrosterone (DHEA), an androgen replacement hormone, for patients with primary adrenal insufficiency (Addison's disease).
Corticotropin Releasing Hormone (CRH) is a hypothalamic hormone made up of 41 amino acids. Amino acids are proteins that when combined make up different substances, like hormones. The order of amino acids in CRH, has been determined, meaning that the hormone can now be synthetically reproduced in a laboratory setting. When CRH is released from the hypothalamus it stimulates the pituitary gland to secrete another hormone, ACTH. ACTH then causes the adrenal glands to make a third hormone, cortisol. This process is known as the hypothalamic-pituitary-adrenal axis. Problems can occur in any of the steps of this process and result in a variety of diseases (Cushing's Syndrome and adrenal insufficiency). Researchers hope that CRH created in a laboratory setting, ovine CRH (oCRH) can be used to help diagnose and treat conditions of the HPA axis. This study will test the relationship for single doses of oCRH in normal volunteers and patients with disorders of the HPA axis. The oCRH will be injected into the patients vein as a single injection or slowly through an IV line over 24 hours. The participants will have blood tests taken to measure hormone levels before, during, and after receiving the oCRH.
