The effect of the weak androgen oxandrolone on psychological and behavioral characteristics in growth hormone-treated girls with Turner syndrome.

Item does not contain fulltextThe weak androgen oxandrolone (Ox) increases height gain in growth-hormone (GH) treated girls with Turner syndrome (TS), but may also give rise to virilizing side effects. To assess the effect of Ox, at a conventional and low dosage, on behavior, aggression, romantic and sexual interest, mood, and gender role in GH-treated girls with TS, a randomized, placebo-controlled, double-blind study was conducted. 133 patients were treated with GH (1.33 mg/m(2)/d) from baseline, combined with placebo (Pl), Ox 0.03 mg/kg/d, or Ox 0.06 mg/kg/d from the age of eight, and with estrogens from the age of 12. The child behavior checklist (CBCL), Junior Dutch Personality Questionnaire (DPQ-J), State-subscale of the Spielberger's State-Trait Anger Scale, Romantic and Sexual Interest Questionnaire, Mood Questionnaire, and Gender Role Questionnaire were filled out before, during, and after discontinuing Ox/Pl. The changes during Ox/Pl therapy were not significantly different between the dosage groups. In untreated patients, the mean CBCL total (P=0.002) and internalizing (P=0.003) T scores, as well as the mean DPQ-J social inadequacy SD score (SDS) (P=0.004) were higher than in reference girls, but decreased during GH+Ox/Pl therapy (P<0.001, P=0.05, P<0.001, respectively). Whereas the mean total (P=0.01) and internalizing (P
