Introduction Cushing’s syndrome (CS) comprises diverse manifestations resulting from chronic exposure to excess glucocorticoids. The incidence is 0.2–5.0 per million people per year. Approximately 80% of endogenous CS is adrenocorticotrophin

Introduction Cushing’s syndrome (CS) is a condition of endogenous hypercortisolism caused by different pathological entities that is classified in two variants: (i) ACTH-dependent CS, due to a corticotroph pituitary adenoma or an ectopic tumor

ACTH-dependent hypercortisolism is highly suggestive of pituitary disease, this is not true for smaller lesions that still might be incidentaloma ( 16 , 17 ). The Consensus Statement on Diagnosis and Complications of Cushing’s Syndrome suggests 6mm as

Introduction Ectopic adrenocorticotrophic hormone (ACTH) syndrome (EAS) is a rare disorder, accounting for 5–15% cases of endogenous Cushing’s syndrome (CS) ( 1 , 2 ). Although initially construed to be caused by malignant tumours (such as

Introduction The differential diagnosis of ACTH-dependent Cushing’s syndrome (CS) as pituitary or ectopic source of ACTH production is often challenging for the physicians as none of the biochemical tests or imaging modalities have 100

Objective: Autonomous cortisol secretion (ACS) is a condition with ACTH-independent cortisol overproduction from adrenal incidentalomas (AI) or adrenal hyperplasia. The hypercortisolism is often mild, and most patients lack typical clinical features of overt Cushing’s syndrome (CS). ACS is not well defined and diagnostic tests lack validation.
Methods: Retrospective study of 165 patients with AI evaluated clinically and by assay of morning plasma ACTH, late-night saliva cortisol, serum dehydroepiandrosterone sulphate (DHEAS), 24-hour urine free cortisol, and cortisol after dexamethasone suppression.
Results: Patients with AI (n=165) were diagnosed as non-functioning incidentalomas (NFI) (n = 82) or ACS (n = 83) according to current European guidelines. Late-night saliva cortisol discriminated poorly between NFI and ACS showing a high rate of false positive (37 %) and false negative (54 %) results. The conventional low dose dexamethasone suppression test (LDDST) did not improve the diagnostic specificity, compared with the 1 mg overnight DST. Receiver operating characteristic curve analysis of DHEAS in the two cohorts demonstrated an area under the curve of 0.76 (p<0.01) with a sensitivity for ACS of 58% and a specificity of 80% using the recommended cutoff at 1.04 µmol/L (40 µg/dL).
Conclusion: We here demonstrate in a large retrospective cohort of incidentaloma patients, that neither DHEAS, late night saliva cortisol nor 24-hour urine free cortisol are useful to discriminate between non-functioning adrenal incidentalomas and ACS. The conventional LDDST do not add further information compared with the 1 mg overnight DST. Alternative biomarkers are needed to improve the diagnostic workup of ACS.

Introduction Cushing’s syndrome (CS), characterized by excessive endogenous cortisol secretion, is in most cases ACTH-dependent. Corticotropin (ACTH) secretion arises from a pituitary adenoma (Cushing’s disease) or, less frequently, from a non
