BACKGROUND Adrenocortical carcinoma is a rare neoplasm characterized by a high risk of recurrence after radical resection. Whether the use of mitotane is beneficial as an adjuvant treatment has been controversial. Our aim was to evaluate the efficacy of adjuvant mitotane in prolonging recurrence-free survival. METHODS We performed a retrospective analysis(More)
OBJECTIVE Subclinical hypercortisolism (SH) may play a role in several metabolic disorders, including diabetes. No data are available on the relative prevalence of SH in type 2 diabetes (T2D). In order to compare the prevalence of SH in T2D and matched non-diabetic control individuals, we performed a case-controlled, multicenter, 12-month study, enrolling(More)
CONTEXT The diagnostic value of tests for detecting hypothalamic-pituitary adrenal insufficiency (HPAI) is controversial. OBJECTIVE Our objective was to compare standard-dose and low-dose corticotropin tests for diagnosing HPAI. DATA SOURCES We searched the PubMed database from 1966-2006 for studies reporting diagnostic value of standard-dose or(More)
There is increasing evidence that the abdominal obesity phenotype may be associated with multiple alterations of the hypothalamic-pituitary-adrenocortical (HPA) axis activity in both sexes. Our hypothesis is that the lack of adequate cortisol suppression after the dexamethasone test may constitute an indirect marker of HPA axis hyperactivity in the presence(More)
OBJECTIVE Obesity can be considered a state of chronic, low-grade inflammation. Particularly, visceral adipose tissue (VAT) seems to be an active compartment in pro-inflammatory molecule secretion. Adipocytes and VAT are able to produce large amounts of monocyte chemoattractant protein 1 (MCP-1), a chemokine directly involved in ventricular remodeling. (More)
The possibility of assessing hypothalamic-pituitary-adrenal (HPA) function by the standard ACTH test (250 microg) has been widely discussed in the past years and compared with the role of the insulin tolerance test (ITT). Recently, it was shown that low doses of ACTH, such as 1 microg i.v., induce a maximal adrenal response and, by reducing the(More)
Oral DHEA administration to patients with hypoadrenalism, in addition to glucocorticoid and mineralcorticoid replacement, may improve both well-being and hormonal/metabolic parameters. Twenty patients (13 men, 7 women, 26-76 yr, 11 with Addison's disease, 9 with central hypoadrenalism) were recruited in a placebo-controlled, randomized study. Hormone(More)
Although primary adrenal failure is considered a rare condition, recent epidemiological studies indicate a rising incidence of the disease owing to the increase of autoimmune disorders. Addison's disease may be a life-threatening condition and the occurrence of pregnancy has been considered as a dangerous event. Nowadays, adrenal insufficiency during(More)
CONTEXT In patients with adrenal incidentalomas, subclinical hypercortisolism (SH) is associated with an increased prevalence of the metabolic syndrome. The effect of surgical/conservative approach is debated. OBJECTIVE The objective of the study was to determine the effect of the surgical and conservative approaches on the metabolic syndrome in patients(More)
