Diagnosis of pituitary pars intermedia dysfunction can be achieved in the field using the dexamethasone suppression test or plasma adrenocorticotropic hormone (ACTH). Equine ACTH is considerably more stable than previously suggested, which makes it useful for field-collected samples. Fasting insulin and circadian cortisol concentration are not discriminating tests. Additionally, season may affe...
INTRODUCTION Cushing's syndrome results from inappropriate exposure to excessive glucocorticoids. Untreated, it has significant morbidity and mortality. CASE OUTLINE A 38-year-old woman with a typical appearance of Cushing's syndrome was admitted for further evaluation of hypercortisolism. The serum cortisol level was elevated without diurnal rhythm, without adequate suppression of cortisol a...
Previous studies have reported divergent findings on the function of the hypothalamic-pituitary-adrenal axis in patients with chronic renal failure (CRF). The low-dose adrenocorticotropin (ACTH) test offers the possibility of unmasking adrenal dysfunction, which might remain undiscovered using the ACTH test with the standard 250-microg dose. Furthermore, the choice of renal replacement therapy ...
OBJECTIVES Giant cell arteritis (GCA) is a chronic systemic vasculitis of large and medium-sized arteries, for which long-term glucocorticoid (GC) treatment is needed. During GC withdrawal patients can suffer adrenal insufficiency. We sought to determine the time until recovery of adrenal function after long-term GC therapy, and to assess the prevalence and predictors for secondary adrenal insu...
Background and Objective: The holy Quran, Mohammad's miracle, is a treasure that was descended on him with the advent of Islam out of which novel and wonderful knowledge and science have been discovered over time. The aim of this study was to investigate the effect of voice of the Holy Quran on cortisol, ACTH and psychological indices during one maximal exercise training in young female athlete...
OBJECTIVE To determine the feasibility of using the combined oral clonidine and the short-ACTH test instead of the sometimes dangerous insulin-induced hypoglycemia test as a screening procedure, for the simultaneous assessment of growth hormone reserve and hypothalamic-pituitary-adrenal axis integrity in children with growth retardation. DESIGN Evaluative study. METHOD Seventy-three childre...
OBJECTIVE Perioperative pituitary-adrenal responses after major abdominal surgery have not been well characterized. The aim of the present study was to further clarify perioperative pituitary-adrenal responses. DESIGN Thirty-six patients (20 men), aged 68+/-10 years (mean+/-SD), undergoing major abdominal operations were studied. Total cortisol (TC), adrenocorticotropic hormone (ACTH), cortic...
Salivary cortisol in low dose (1 microg) ACTH test in healthy women: comparison with serum cortisol.
To date, a single report has appeared on the use of salivary cortisol for adrenal function testing with a low dose ACTH, although 1 microg has become preferred as a more physiological stimulus than the commonly used 250 microg ACTH test. Our present study was aimed to obtain physiological data on changes of free salivary cortisol after 1 microg ACTH stimulation. This approach was compared with ...
BACKGROUND Overcommitment (OC) is a pattern of excessive striving that has been associated with alterations in the hypothalamus-pituitary-adrenal (HPA) system. To investigate whether overcommitment is associated with alterations in HPA system function we measured cortisol and adrenocorticotropin (ACTH) release in response to the combined dexamethasone/CRH test. METHODS We recruited 92 men and...
