Clin Endocrinol:雌激素治疗可增加神经性厌食女孩BMD

2013-09-03 佚名 丁香园

神经性厌食(AN)的青少年是有闭经,并且有骨量增长减少和低骨矿密度(BMD)。间充质干细胞分化调节是一种调节骨形成的重要因素。前脂肪细胞因子1(Pref-1),一种脂肪细胞和成骨细胞分化的抑制剂,在雌激素缺乏状态下升高。为了探讨AN的青春期女孩雌二醇经皮给药对Pref-1的影响,并检测Pref-1变化与腰椎BMD和骨转换标志物变化之间的关系,来自美国哈佛大学医学院的Anne

神经性厌食(AN)的青少年是有闭经,并且有骨量增长减少和低骨矿密度(BMD)。间充质干细胞分化调节是一种调节骨形成的重要因素。前脂肪细胞因子1(Pref-1),一种脂肪细胞和成骨细胞分化的抑制剂,在雌激素缺乏状态下升高。为了探讨AN的青春期女孩雌二醇经皮给药对Pref-1的影响,并检测Pref-1变化与腰椎BMD和骨转换标志物变化之间的关系,来自美国哈佛大学医学院的Anne Klibanski教授及其团队进行了一项研究,该研究发现AN青春期女孩使用雌激素后Pref-1下调。AN女孩Pref-1的抑制可能由雌二醇经皮替代治疗对BMD的有益影响介导。该研究结果发表在2013年9月的Clinical Endocrinology杂志上。【原文下载

该研究中,横断面研究AN青春期女孩和正常体重对照者。在一项双盲研究中,接受雌二醇经皮给药(加用周期性甲羟孕酮)或安慰剂治疗12个月,纵向调查AN女孩。在基线研究69例13-18岁女孩(44例为AN,25例为正常体重对照者),22例AN女孩之后进行前瞻性研究。测量Pref-1水平、骨形成和骨吸收标志物和BMD.该研究结果表明,尽管在基线时,AN女孩与对照组相比,Pref-1水平没有差别,与安慰剂组相比,雌二醇经皮给药组治疗后AN女孩Pref-1水平下降。12个月期间Pref-1的变化与腰椎BMD变化呈负相关,而与CTX变化呈正相关。

该研究发现,AN青春期女孩使用雌激素后Pref-1下调。AN女孩Pref-1的抑制可能由雌二醇经皮替代治疗对BMD的有益影响介导。
