47.下列何者最可能出現嗜酸性球增多症？

A history that is suggestive of adrenal insufficiency, including the use and tapering of corticosteroids, can provide a clue that the observed eosinophilia is associated with adrenal insufficiency. Hypoadrenalism (ie, Addison disease) is the most common endocrine abnormality associated with eosinophilia.

其實課本沒有說Addison's disease會造成嗜酸性球增多症，但網路上查是找的到的

論文所推測的可能原因 Corticosteroids exert eosinopenic effects, at least in part, by stimulating eosinophil apoptosis4. It has been suggested that the presence of relative eosinophilia in critically ill patients is associated with clinical signs of adrenal insufficiency
