Podcast 548:  Adrenal Crisis

Contributor: Nick Tsipis, MD

Educational Pearls:

  • Congenital adrenal hyperplasia (CAH) is a group of enzyme deficiencies in the adrenals leading to a deficiency of hormones normally synthesized by the adrenals (mineralocorticoids, glucocorticoids, androgens)
  • 21-hydroxylase is most commonly the deficient enzyme.
  • 21-hydroxylase is needed to produce aldosterone and cortisol, and those with chronic cortisol deficiencies need daily steroid replacement
  • Aldosterone, made in the kidney as part of the renin-angiotensin-aldosterone system (RAAS), increases blood pressure via salt and water retention to maintain adequate organ perfusion
  • Adrenal crisis results in a loss of cortisol leading to hypoglycemia and potential CNS depression with hypotension, hypoglycemia, and hyponatremia
  • Patients in adrenal crisis need salt, volume, and glucose replacement
