Abstract:
The objective was to determine the probability of receiving steroid treatment following an insulin tolerance test (ITT) for short-stature evaluation and to evaluate the utility of a subsequent cortrosyn stimulation test (CST) in determining adrenal sufficiency. We retrospectively analyzed the hypothalamic-pituitary-adrenal (HPA) axis evaluation in short-stature subjects during the 5-year period from January 2005 to December 2009. The probability of receiving steroid treatment was < 10% when the maximum cortisol concentration during an ITT was < 8.4 microg/dL. In the event of a suboptimal cortisol response during an ITT, only a single 1-microg CST is recommended for assessment of adrenal function.

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. Congenital adrenal hyperplasia, a genetic ailment causing...
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...

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.
