Suppression of adrenal function by low-dose prednisone: assessment with 24-hour urinary steroid hormone profiles--a review of five cases.(Case Study: Adrenal Suppression)

Abstract

The impact of the synthetic glucocorticoid prednisone on adrenal steroid hormone production was examined using 24-hour urinary steroid hormone profiling. Five women, who were chronically taking low-dose prednisone, were tested, and the relevant literature was reviewed. As expected, adrenal glucocorticoid production, measured by urinary terminal cortisol and cortisone metabolites, was markedly suppressed compared to reference range values (p=0.03). Urinary cortisol and cortisone, reflecting circulating glucocorticoids, were decreased to a lesser extent than their…
