Abstract

Cortisone is derived from the peripheral metabolism of cortisol and lacks biological activity. The rapid interconversion between cortisol and cortisone has been well established. The altered equilibrium between these steroids may regulate glucocorticoid activity in various tissues. We evaluated the serum levels of cortisol and cortisone, and the cortisone/cortisol ratio in ten children with adrenal diseases using reversed-phase high performance liquid chromatography. Children with hypoadrenalism exhibited a greater decrease in cortisol as compared with cortisone. Cortisone levels were higher than cortisol levels, and the cortisone/ cortisol ratio exceeded 1.0. Children with adrenal cancer exhibited normal or high values of cortisol, whereas cortisone levels were decreased and the cortisone/cortisol ratio was decreased to nearly zero. The ratio returned to normal after the excision of adrenal tumors. The simultaneous evaluation of cortisol, cortisone, and cortisone/cortisol ratio provides a clinical clue of adrenal diseases.

Addison Disease

Addison's disease, also known as primary adrenal insufficiency and hypocortisolism, is a long-term endocrine disorder in which the adrenal glands do not produce enough steroid hormones. Discover the latest research on Addison's disease here.
