Filter by: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.
Randomized controlled trial evaluating the duration of steroid replacement therapy in patients with adrenal insufficiency and septic shock. Patients will be randomized to receive either hydrocortisone 50 mg IV every six hours for seven days (control) or hydrocortisone 50 mg IV every six hours until 24 hours after achievement of hemodynamic stability (MAP > 65 mm Hg off of vasopressors).
The purpose of this study is to see if stress doses of hydrocortisone improve early outcome in patients who are in early stage of ARDS and with relative adrenal insufficiency.
Relative adrenal insufficiency (RAI) is an well known condition in patients with septic shock. Liver failure (including chronic liver failure)and sepsis are both characterized by hyperdynamic circulatory failure (with low arterial pressure) and high levels of pro-inflammatory cytokines. Hydrocortisone has been shown to have a beneficial effect on clinical outcome. The aim of this study is to evaluate the incidence of RAI in the different settings of ascites in cirrhosis and the usefulness of hydrocortisone in this context.
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.
Observational study about the incidence of relative adrenal insufficiency in patients with cirrhosis and acute variceal bleeding; in patients with acute peptic gastrointestinal bleeding and without liver disease; and in patients with severe acute pancreatitis. This is a study using pharmaceutical specialties in the approved conditions of use.
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.
Inhaled corticosteroids are largely used in patients with asthma or chronic obstructive lung diseases. The purpose of this study is to determine if the use of inhaled corticosteroids is associated with suppression of endogenous cortisol production, as seen in patients treated with pharmacologic doses of oral or parenteral steroids.
