Serum cortisol appearance-disappearance in adrenal insufficiency after oral cortisone acetate
Abstract:
Six patients with long-standing idiopathic primary adrenal insufficiency were given 25 mg of cortisone acetate orally on two occasions. Circulating serum cortisol levels were determined hourly for five hours after ingestion. Two patients were additionally studied with an oral dose of 20 mg of cortisol. Marked patient to patient variation in peak hormone and in fifth hour hormone levels was observed. Both values were lowest in the two chronically symptomatic patients who had been maintained on empiric glucocorticoid replacement. Specific information on blood cortisol levels in treated Addisonian individuals has not been previously reported.

Anatomy of the Adrenal Glands
These glands possess a distinctive yellow tinge due to the stored cholesterol and fatty acids required for hormone synthesis. They are encased in a fibrous capsule and cushioned by fat.

Hormones of the Adrenal Glands
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and corticosterone...
Adrenal Gland Disorders
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss.
