Q

Initial orders (4) on a 40 year old woman at clinic with weakness, fatigue, depression, orthostatic hypotension, skin hyperpigmentation, weight loss, anorexia x 8 months?

Follow-up, diagnostic orders (2.)?

A
  • think Addison disease aka chronic adrenal insufficiency*

    2) ECG
    3) CBC
    4) BMP (should show hyperkalemia)
  1. Early morning cortisol level (IF LOW/undetectable, diagnostic of Addison. If Intermediate, go to step 2)
  2. ACTH (cosyntropin) stimulation test (ACTH given, cortisol measured at 0, 30, & 60 min. If cortisol remains low, diagnostic of Addison. If cortisol increases at 30/60min, it’s pituitary or hypothalamic dysfxn/secondary hypoadrenalism
