Dehydroepiandrosterone Sulfate Levels Are not Suppressible by Glucocorticoids before Adrenarche*

Abstract

We measured dehydroepiandrosterone sulfate (DHEA-S) levels in children before and after high dose prednisone therapy. In older children (postadrenarchal), there was a 70% decrease in DHEA-S levels after 1 week. However, even after a month of therapy, DHEA-S was detectable in serum. In contrast, in younger (preadrenarchal) children, the low initial DHEA-S levels were not decreased by prednisone therapy. These findings suggest that there are two distinct regulatory pathways leading to DHEA-S, one of which is independent of ACTH.
