A rare but severe condition caused by a sudden defective production of adrenal steroids (cortisol and aldosterone). It represents an emergency and may occur at any age.

Laboratory exams show signs of adrenal insufficiency (hypoglycemia, hyponatremia and elevated natriuresis, hyperkaliemia, hemoconcentration, hypochloremic metabolic acidosis and functional renal failure) confirmed by hypocortisolemia, increased adrenocorticotropic hormone (ACTH) and an insufficient response to rapid ACTH stimulation testing.
