BACKGROUND Glucocorticoids influence the synthesis and metabolism of catecholamines (epinephrine and norepinephrine) and metanephrines (metanephrine and normetanephrine). The aim of this study was to measure urinary catecholamines and metanephrines in dogs with hypercortisolism before and during trilostane therapy. Urine samples were collected during initial work up and during therapy with tril...
Epidural corticosteroid injection is a commonly used approach for managing back pain of several etiologies. The risk of clinical complications from systemic absorption is felt to be rare. Ritonavir is a protease inhibitor whose potent cytochrome P450 3A4 inhibition is exploited for pharmacologic boosting in human immunodeficiency virus (HIV) infection. It has been associated with systemic hyper...
HISTORY AND CLINICAL FINDINGS A 29-year-old woman was found to have arterial hypertension (175/115 mm Hg). The 24-hour profile showed no diurnal cortisol variations with normal concentrations and 24-hour urinary cortisol was normal. 14 months later there was definite hypercortisolism with discrete Cushing signs and no amenorrhoea. She also had signs of depression. INVESTIGATIONS Routine labor...
BACKGROUND Although prognostic parameters are important to guide adjuvant treatment, very few have been identified in patients with completely resected adrenocortical carcinoma (ACC). OBJECTIVE To assess the prognostic role of clinical symptoms of hypercortisolism in a large series of patients with completely resected ACC. DESIGN, SETTING, AND PARTICIPANTS A total of 524 patients followed a...
BACKGROUND Salivary cortisol is increasingly used to assess patients with suspected hypo- and hypercortisolism. This study established disease-specific reference ranges for an automated electrochemiluminescence immunoassay (ECLIA). METHODS Unstimulated saliva from 62 patients with hypothalamic-pituitary disease was collected at 0800 h. A peak serum cortisol level below 500 nmol/l during the i...
Among endocrine disorders, Cushing's syndrome (CS) is certainly one of the most challenging to endocrinologists due to the difficulties that often appear during investigation. The diagnosis of CS involves two steps: confirmation of hypercortisolism and determination of its etiology. Biochemical confirmation of the hypercortisolaemic state must be established before any attempt at differential d...
It has been shown that ingestion of glucose, amino acids, protein or mixed meals tends to increase serum and salivary cortisol concentrations in healthy adults. Recently, it has been demonstrated that morning glucose ingestion stimulates pulsatile cortisol and adrenocorticotropic hormone (ACTH) secretion, thus elevating their mean concentrations. In light of the above, a question arises: could ...
Cushing syndrome (CS), due to an ACTH-secreting pituitary adenoma, adrenal tumors, or ectopic ACTH secretion, causes hypercortisolism. CS is associated with major morbidity, especially metabolic and cardiovascular complications, osteoporosis, psychiatric changes, and cognitive impairment. Despite biochemical "cure" of hypercortisolism and clinical improvement after effective treatment, these co...
Ectopic production of adrenocorticotropic hormone by carcinoid tumors is relatively uncommon and may not be recognized by physicians. This report describes a woman who had Cushing syndrome from the ectopic secretion of adrenocorticotropic hormone by a carcinoid tumor. Her cause of death was a pneumonia that may have been secondary to her untreated hypercortisolism. There are threeinstructive el...
BACKGROUND Depression in unipolar and bipolar disorders is associated with hypothalamic-pituitary-adrenal-axis (HPA-axis) hyperactivity. Also, unipolar disorder has recently been shown to exhibit HPA-axis hypoactivity. We studied for the first time how HPA-axis hypo- and hyperactivity relate to depression and disease burden in bipolar disorder. We were interested in studying hypocortisolism; ch...
