Introduction: Primary adrenal insufficiency (PAI) leads to a drastically reduced production of steroids from the adrenal cortex, but a few patients may keep some residual adrenal steroid secretion that may simplify replacement therapy and prevent adrenal crisis. Irrespectively, the conventional glucocorticoid (GC) replacement therapy, using thrice-daily oral hydrocortisone, does not restore the patients’ physiological cortisol profile.Objective: The...

Introduction: Gas chromatography tandem mass spectrometry (GC-MS/MS) quantitatively detects a large number of steroids at one time in a single serum sample. Most studies of subclinical hypercortisolism in adrenal incidentalomas have focused on detection of a few steroids like cortisol, DHEA/S, androstenedione, testosterone. We used GC-MS/MS to quantify 91 steroids in patients with adrenal incidentalomas to search for the most reliable marker of subclinical hypercortisolism.</p...
