Final adult height of girls with central precocious puberty or early and fast puberty could be improved by treatment of gonadotropin-releasing hormone analogs / 中华内分泌代谢杂志

ABSTRACT

Objective To assess the efficacy and impact factors of treatment with Gonadotropin-releasing hormone analogs (GnRHa) in central precocious puberty (CPP) or early and fast puberty (EFP) girls in a retrospective unicenter study.Methods One hundred and two girls (75 CPP and 27 EFP) were treated with GnRHa alone and were followed up to their final adult hight (FAH).Results FAH was (158.0 ± 4.8) cm,being significantly higher than pretreatment predicted adult height [(151.1 ±5.1) cm,P＜0.01].There was no significant difference between CPP [(7.3 ± 4.4) cm] and EFP [(5.5 ± 4.5) cm] in net height gain.There was no significant improvement in FAH and pretreatment PAH for the patients who had menarche before treatment or whose growth velocity was less than 4 cm during the first year.Conclusion GnRHa treatment improves FAH efficiently for both CPP and EFP girls.Nevertheless,those who had menarche before treatment or whose growth velocity was less than 4 cm during the first year can hardly improve FAH by GnRHa treatment alone.
