Criteria

Inclusion Criteria:

  • Patients will be eligible for inclusion if: they are males and over 18, lack clinical features classically associated with Cushing's syndrome; have evidence of excess circulating cortisol

Exclusion Criteria:

  • Evidence of local or systemic malignancy; overt Cushing's syndrome; severe uncontrolled diabetes mellitus or hypertension; pregnancy; clinically significantly impaired cardiovascular function (e.g. stage IV cardiac failure); severe liver disease (liver enzymes ≥ 3 x the institutional upper limit of normal range); significantly impaired renal function (eGFR <30/min); uncontrolled severe active infection; treatment with approved or experimental steroidogenesis inhibitors, adrenolytic agents, within four weeks of admission; In women, known endometrial cancer, history of endometrial hyperplasia or vaginal bleeding of unknown cause; requirement for inhaled or systemic glucocorticoids for existing disease; impaired mental capacity or markedly abnormal psychiatric evaluation that precludes informed consent.
