Introduction: Adrenocorticotropin (ACTH)-independent macronodular adrenal hyperplasia (AIMAH) is a rare cause of Cushing’s syndrome, commonly involving the aberrant expression of several membrane-bound adrenal receptors. Recent studies have investigated whether the latter is also implicated in the renin-independent aldosterone secretion of hyperaldosteronism cases.Case report: A 35-year-old man presented to our department for evaluation of new-onset...

Background: Hormonal activity and insulin resistance (IR) in patients with incidentally discovered bilateral adrenal adenomas (BA) has not been evaluated until now. Therefore, we have investigated cortisol and aldosterone secretion and IR in 29 patients with BA, in 113 patients with unilateral adrenal adenomas (UA) and in 89 healthy subjects (C).Methods: All subjects underwent the following investigation: 1) Low dose dexamethasone suppression test (LDDST...

Introduction: Patients with adrenal adenomas appear to exhibit an appreciable prevalence of autonomous aldosterone secretion (AAS). Our aim was to evaluate the anti-hypertensive effect of targeted therapy with mineralocorticoid receptor (MR) antagonists in AAS patients.Patients and methods: We studied 60 hypertensive patients, 21 males and 39 females, harboring an adrenal adenoma with AAS. All patients were receiving combination of anti-hypertensive trea...

Background: Multiple endocrine neoplasia type 1 (MEN1) syndrome is an autosomal dominant disorder characterized by the presence of endocrine and nonendocrine tumors. Until recently, more than 450 different germline mutations have been reported in MEN1 patients involving frameshift deletions, insertions, as well as nonsense mutations.Aim: To report a novel mutation in MEN1 gene in a young female with persisting primary hyperparathyroidism.<p class="ab...
