Salivary cortisol is an increasingly popular tool in endocrine, psychological and sports studies. Immunoassays used for its measurement are limited by cross-reactivity from related steroids, mainly cortisone, which is abundant in saliva.A method was developed for the simultaneous measurement of cortisol and cortisone (SalF and SalE respectively) in saliva using LC-MS/MS. 40 μl of extract was injected onto a C8 4×2 mm guard cartridge attached to...

The diagnosis of subclinical hypercortisolism (SH) is a challenging issue, especially as the high prevalence of adrenal incidentalomas (AI) is increasingly recognized. The diagnosis of subclinical hypercortisolism relies on a combination of tests that include overnight (ODST) or low dose dexamethasone suppression (LDDST), plasma ACTH, and 24-h urinary free cortisol (UFC). Late night salivary cortisol (LNSC) has been successfully used in the diagnosis of Cushing’s syndrome...

Inherited CBG deficiencies are rarely reported and only 3 causative mutations in 4 families have been described. The objective of this study was to investigate a family with potential CBG deficiency.The index case, a 29-year-old female of Pakistani origin with consanguineous parents, presented with hirsutism and a slightly elevated 17-OHP. In a subsequent Short Synacthen Test (SST) 17-OHP was normal but serum cortisol (SerC) values were abnormal (case 1 ...
