Traumatic brained injured (TBI) patients frequently suffered from glucocorticoid insufficiency that is associated with a raise in the rate of pneumonia. In a placebo-controlled, multi-center, double-blinded trial, treatment of glucocorticoid insufficiency (hydrocortisone associated with fludrocortisone) will be assessed for prevention of post trauma pneumonia in a population of severe TBI patients.
Role fo oxidative stress in adrenal insufficiency has not been studied. The degree of oxidative stress and it's role in pediatric critical illness is unknown. Potential for significant alterations to many of thew body's regulatory pathways may result from severe oxidative stress. Further is needed to delineate what if any role oxidative stress may play
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.
The objective of this study is to estimate the prevalence of relative adrenal insufficiency in preterm very low birth weight infants with and without shock.
This is a randomised, controlled, open, two-armed, two-period cross-over, multi-centre phase II/III study to assess the safety, tolerability and pharmacokinetics of once-daily oral modified-release hydrocortisone in comparison to conventional thrice-daily oral hydrocortisone tablets in patients with adrenal insufficiency
Objectives: To establish valid serum total cortisol and salivary cut-offs for use with the short Synacthen test in patients with normal CBG concentrations. To investigate, using current assays, the effect of assay differences on the serum total cortisol cut-off. To explore the performance of these cut-offs in groups of patients with suspected adrenal insufficiency and high and low serum CBG concentration. Methodology: An ACTH test (250 micrograms iv ACTH1-24) will be undertaken in healthy volunteers, women taking an oestrogen-containing oral contraceptive pill (OCP), patients with adrenal insufficiency and patients with low serum albumin. Serum cortisol in the samples collected from healthy volunteers will be measured using GC-MS, Advia Centaur (Siemens), Architect (Abbott), Modular Analytics E170 (Roche), Immulite 2000 (Siemens) and Access (Beckman) automated immunoassays. The estimated lower reference limit for the 30 min cortisol response to ACTH, defined as the 2.5th percentile of log-transformed concentrations, will be determined in this healthy population and used as a cut-off in the patient groups studied.
30 adolescent girls and young women between 13 and 26 years with central adrenal insufficiency and a grand shortage of DHEA are recruit. The clinical trial is double-blind to show that the substitution of the hormone DHEA stimulates secondary hair growth, enhances well being and mood of the patients. It should also normalize the serum content of DHEA, aldosterone and testosterone.
Megestrol Acetate (MA) is a progesterone-like hormone that has been utilized as a birth control agent, chemotherapeutic drug, and more recently, to induce appetite and weight gain in patients malnourished as a result of radiation therapy, chemotherapy, cystic fibrosis, AIDS, or dementia. The mechanism of MA-stimulated appetite and weight gain is unknown. Although only approved to combat weight loss associated with AIDS and cancer, MA is frequently prescribed for long periods of time to prevent or reverse weight loss in nursing home residents and in elderly patients with serious illnesses in the community. Little data is available to support this practice. Among its many properties, MA acts as a partial glucocorticoid agonist, and long term and short term use of MA may results in adrenal suppression. The rapidity of the onset of MA-induced adrenal suppression and the time course of resumption of normal adrenal function after discontinuation of MA is completely unknown. As a consequence, it is unclear whether MA can be given safely for short periods of time or whether glucocorticoid administration is necessary after abruptly stopping MA treatment. The increased use of MA in the frail elderly, where even partial adrenal insufficiency may pose a substantial risk of adrenal crisis after an illness, requires a clear understanding of these issues. To address these concerns, we will evaluate adrenal function before, during, and after MA administration in healthy volunteers between the ages of 60 and 85 years.
The use of intravitreal corticosteroids in the management ocular inflammatory diseases has recently gained widespread acceptance. The purpose of this study is to determine if the use of intravitreal triamcinolone is associated with suppression of endogenous cortisol production, as generally admitted for patients treated with oral or parenteral corticosteroid therapy.
