Endocrine Conditions: Systemic Steroids & Autoimmune Conditions Flashcards
Cortisol replaced by giving…..
any steroids
Aldosterone replaced by giving…..

Fludrocortisone info
mimis aldosterone
helps keep balance of water and electrolytes
FDA approved for Addison’s disease and off-label for orthostatic hypotension
Suppression of Hypothalamic-pituitary-adrenal axis (HPA)
systemic steroids can cause adrenal gland to stop producing cortisol due to feedback inhibition
need to be tapered off when stoping long term steroids
Cushings syndrome
can develop when adrenal gland produces too much cortisol or too many steroids taken at higher doses
Addison’s disease
opposite of Cushings
adrenal gland not making enough cortisol
if stop taking steroids used to help inc cortisol, can have addisonian crisis = volume depletion and hypotension = can be fatal
