    Description / Table of Contents: Summary Background: It is still controversial, whether the end metabolites of peripheral androgen metabolism, 5 α-androstane-3 α, 17 β-diol and 5 α-androstane-3 α, 17 β-diol glucuronide, represent biochemical markers of hirsutism. Furthermore, discrepant plasma concentrations have been reported in the literature. Method: Using stable isotope dilution/gas chromatography-mass spectrometry, the most specific method in steroid analysis, we investigated healthy females and patients with hirsutism of various etiology. Results: Generally, both androstanediol and androstanediol-glucuronide scattered much in hirsute patients. Patients with adrenal enzyme defects (3 β-hydroxysteroid-dehydrogenasedeficiency, 21-hydroxylase-deficiency) had elevated androstanediol and androstanediol-glucuronide. Hirsute Patients with hyperandrogenaemia but without adrenal enzyme deficiencies had normal androstanediol in 33 % and normal androstanediol-glucuronide in 24 % of cases. 54 % of patients with idiopathic hirsutism had normal androstanediol and 24 % had normal androstanediol-glucuronide. Conclusion: Our results show, that neither androstanediol nor androstanediol-glucuronide are consistently elevated in hirsutism and that both do not discriminate between the various causes of hirsutism.
    Notes: Zusammenfassung Hintergrund: Ob die Endmetaboliten des peripheren Androgenstoffwechsels, 5 α-Androstan-3 α, 17 β-diol und 5 α-Androstan-3 α, 17 β-diol-glukuronid, biochemische Marker bei Hirsutismus darstellen, wird kontrovers diskutiert. Über die Plasmakonzentrationen beider Parameter gibt es ferner erhebliche Diskrepanzen bei den in der Literatur berichteten Werten. Methode: Unter Einsatz von Isotopenverdünnungs-Gaschromatographie-Massenspektrometrie, dem Verfahren mit der höchsten Spezifität in der Steroidanalytik, untersuchten wir gesunde Mädchen und Frauen sowie Patientinnen mit Hirsutismus unterschiedlicher Ätiologie. Ergebnisse: Bei hirsuten Patientinnen streuten beide Parameter stark. Bei Patientinnen mit adrenalen androgenisierenden Enzymdefekten (3 β-Hydroxysteroiddehydrogenasemangel, 21-Hydroxylasemangel) waren sowohl Androstandiol als auch Androstandiolglukuronid erhöht. Hirsute Patientinnen mit Hyperandrogenämie ohne adrenalen Enzymdefekt wiesen in 33 % normales Androstandiol und in 24 % normales Androstandiolglukuronid auf. Patientinnen mit idiopathischem Hirsutismus hatten in 54 % Androstandiol- und in 30 % Androstandiolglukuronidkonzentrationen innerhalb des Streubereichs gesunder Mädchen und Frauen. Schlußfolgerungen: Unsere Ergebnisse zeigen, daß weder Androstandiol noch Androstandiolglukuronid in allen Fällen von Hirsutismus erhöht sind und daß beide Parameter nicht zwischen unterschiedlichen Formen des Hirsutismus diskriminieren.

    Notes: Abstract 8 children with precocious puberty were treated with cyproterone acetate (CPA). During treatment there were no definite clinical signs of depressed adrenocortical function. The plasma cortisol concentrations were grossly depressed and the diurnal cortisol rhythm was abolished. Two months after discontinuation of CPA treatment the adrenocortical function had greatly improved. The lysin-vasopressin stimulation test revealed in one child a normal, in another child an exaggerated ACTH response during CPA therapy. Fasting plasma ACTH concentrations were elevated compared with normal controls, but they were very low compared with patients with Addison's disease. The results suggest that CPA has a twofold effect leading to adrenocortical insufficiency: i.e., inhibition of cortisol secretion by the adrenals themselves and inhibition of ACTH secretion at the hypothalamo-pituitary level.
