Abstract

To provide clinical guidelines for the use of high-dose short-term glucocorticoid therapy, we studied recovery of the hypothalamicpituitary-adrenal axis in 10 normal men following the administration of suppressive doses of prednisone (25 mg twice daily for five days). Cortisol responses to insulin-induced hypoglycemia and synthetic ACTH before treatment were compared with responses two and five days after concluding the prednisone course when adrenal function was not influenced by the presence of exogenous steroid. Two days after prednisone therapy, peak cortisol responses to both hypoglycemia (11.0 ± 0.9 μg/dl mean ± SEM) and synthetic ACTH (13.3 ± 1.4 μg/dl) were significantly reduced compared to pretreatment (20.6 ± 1.6 and 27.3 ± 2.5 μg/dl, respectively, p < 0.001). Five days after concluding the prednisone therapy, peak cortisol response to hypoglycemia had returned to near pretreatment levels although peak cortisol response in the adrenal gland to synthetic ACTH (22.3 ± 1.1 μg/dl) remained reduced (p < 0.05). These data suggest that brief courses of high-dose prednisone therapy may limit the adrenal component of the hypothalamic-pituitary-adrenal response to stress for up to five days.
