Abstract

INTRODUCTION: Spontaneous puberty occurs in 30% of patients with Turner Syndrome. Its absence is an indication for hormone replacement therapy (HRT). No reliable markers of spontaneous puberty have been defined to date. AIM OF THE STUDY: To evaluate the usefulness of antymüllerian hormone (AMH) and inhibin B assessment in predicting ovarian function and spontaneous puberty in girls with TS. MATERIAL AND METHODS: The study included 35 TS patients treated with human recombinant growth hormone (rhGH). Gonadal axis function parameters (LH, FSH and estradiol) were evaluated at the age of physiological puberty (10-12 years, mean 10.5 years), before introduction of HRT. Ad-ditionally AMH and inhibin B levels were assessed. In follow up patients were divided into 2 groups: with (SP) and without (WP) spontaneous puberty. Spontaneous puberty was defined as Tanner stage 2 or higher breast development. RESULTS: WP patients were observed until the mean age of 16y. SP occurred in 16 patients (mean age 10 years). Patients with SP presented with significantly lower mean FSH level (1.14-91.1 mIU/ml, mean mIU/ml 24.5 vs. 7.7-196.4 mIU/ml, mean 66.5 mIU/ml, p = 0.002), higher mean estradiol (10.5-68.8 pg/ml, mean 28.4 pg/ml vs. 6.1-26.0 pg/ml, mean 14.9 pg/ml, p = 0.005), AMH (0.0-3.11 ng/ml, mean 0.8 ng/ml vs. 0.0-0.002 ng/ml, mean 0.003 ng/ml, p = 0.001) and inhibin B (0.0-110.0 pg/ml, mean 29.1 pg/ml vs. 0.0-11.0 pg/ml, mean 1.06 pg/ml, p = 0.026) levels. In three SP patients without elevated FSH level (FSH < 35 mIU/ml) we found zero concen-tration levels of AMH and inhibin B. SP patients had mosaic (non 45,X) karyotype in 87.5% and WP patients only in 47%. CONCLUSIONS: AMH and inhibin B assessment may be a valuable complement to the diagnosis of ovarian function in patients with TS. Low levels of these parameters may indicate a risk of ovarian failure even in patients with spontaneous puberty and without hypergonadotropic hy-pogonadism.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
