Prednisone is not only glucocorticoid? Dexamethasone doesn't interfere with cosyntropin stimulation test?

Guys, I am learning a lot here! nod

Aashi , can we have your reasoning behind those answers?


Being on chronic prednisone t/t------>his H-PAxis is under negative feedback and thus his cortisol level is low putting him at risk for increased severity/morbidity of seemingly mild infections.

Then as his cortisol level is low, he needs steroids but we also need to know about his HPitu function, so dexa + stim test is ideal.Moreover dexa does not interfere with stim test.

I have a question:
Does hyponatremia is expected in SECONDARY adrenal insufficiency?
(where are you, Aashi?!!!)

  #33

Weakness, abdominal pain, fever, confusion, nausea, vomiting, and diarrhea.
Low blood pressure, dehydration; skin pigmentation may be increased.
Serum potassium high, sodium low, BUN high.

are all S/S of acute adrenocortical insufficiency.
