Which one of the following is the true statement regarding adrenal suppression secondary to steroid therapy?
Correct Answer: It should be expected in anyone receiving > 5mg, Prednisolone daily
Description: Supression of hypothalamo pituitary axis occur depending on the dose and duration of therapy. It occurs when hydrocoisone (>20-25mg/day) or equivalent is given for more than 2-3weeks. Prednisolone is 5 times more potent than hydrocoisone and therefore 5 mg prednisone is equivalent to 25 mg Hydrocoisone. Thus, suppression of HPA should be expected in any patient who has received > 5mg prednisolone/day for more than 2- 3 weeks. With the administration of steroids adrenal coex atrophies, and stoppage of exogenous steroid can precipitate a withdrawal syndrome. Withdrawal syndrome is characterized by fever, malaise, weakness, pain in muscles and joints, and reactivation of the disease. When subjected to stress these patients undergo acute adrenal insufficiency.
