  • Title: Correlation of the effects of dexamethasone administration on urinary 17-ketosteroid and serum androgen levels in patients with hirsutism.
    Author: Judd HL, McPherson RA, Rakoff JS, Yen SS.
    Journal: Am J Obstet Gynecol; 1977 Jun 15; 128(4):408-17. PubMed ID: 141210.
    Abstract:
    Total 24 hour urinary 17-ketosteroid and serum testosterone (T), androstenedione (delta), dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DS), and cortisol levels were measured before and during four days of dexamethasone administration in 28 hirsute patients and 10 women with normal ovulatory cycles. Both the base-line urinary 17-ketosteroids and serum androgen levels were significantly higher (p less than 0.05) in hirsute than in normal subjects. Cortisol levels were similar in the two groups. Dexamethasone administration resulted in a significant suppression (p less than 0.05) of all the urinary and serum androgen and cortisol levels in both groups. At the end of suppression the serum DHEA, DS and cortisol levels were similar, while the urinary 17-ketosteroids and serum T and delta levels were still significantly higher (p less than 0.05) in the hirsute than in normal women. There was poor correlation between total urinary 17-ketosteroid and serum androgen results. These finding suggest there is a dual abnormality of androgen production in hirsute patients. The adrenal glands appear to secrete increased quatities of DHEA and DA, while the ovaries appear to produce elevated amounts of T and delta.
