    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: Summary Normal growth and development, as well as the prevention of overweight, are major goals in the treatment of paediatric patients with insulin-dependent diabetes mellitus (IDDM). We therefore evaluated longitudinally the anthropometric measurements of height and weight, as well as bone age, in an unselected group of 389 patients with IDDM treated at one institution. In order to identify genetic influences on these parameters, height and weight were determined in 186 unaffected siblings and 177 pairs of parents. At diagnosis, patients were slightly taller than average (median z score: +0.37). During the subsequent course of diabetes, age-adjusted heights decreased progressively for the first 9 years, catching up again after more than 10 years of diabetes. Bone ages were progressively retarded with increasing duration of diabetes. In 76 patients of 18 years or older, median z-score for height was +0.30, not different from their unaffected siblings (median z-score: +0.22). The correlation with midparental height was identical for diabetic and nondiabetic siblings (r=0.43). In contrast, children with diabetes were significantly heavier (z-score for weight: +0.74 compared to +0.34 in unaffected siblings; p〈0.002). Obesity developed primarily during and after puberty. We conclude that: 1) during the course of diabetes, longitudinal growth is temporarily reduced and maturation is delayed in children with diabetes compared to unaffected siblings. However, this effect of diabetes is transient and small compared to genetic influences on height in an individual child. 2) As a group, children with IDDM become significantly overweight, which is likely to increase the cardiovascular risk during adulthood.
