Hum Reprod Update:抗苗勒氏管激素在预测卵巢反应性上优于窦卵泡计数

2015-10-27 candy 译 MedSci原创

背景:对于政策制定者和医疗保健提供者来说分层个性化医学已被公认为是一个重要的优先事项。个体化护理的主要原则是利用患者的特点和生物标志物来预测预后,调整治疗和预测治疗结果。在生殖医学中,已经提出了各种各样的生物标志物作为预测卵巢反应;比如苗勒氏管激素(AMH)和窦卵泡计数(AFC),据说是在分析和性能特点上表现最有利的。以前AFC和AMH本质上是可替换的,然而,最近的试验数据质疑这个假设。目的:这篇

对于政策制定者和医疗保健提供者来说分层个性化医学已被公认为是一个重要的优先事项。个体化护理的主要原则是利用患者的特点和生物标志物来预测预后,调整治疗和预测治疗结果。在生殖医学中,已经提出了各种各样的生物标志物作为预测卵巢反应;比如抗苗勒氏管激素(AMH)和窦卵泡计数(AFC),据说是在分析和性能特点上表现最有利的。以前AFC和AMH本质上是可替换的,然而,最近的试验数据质疑这个假设。

这篇评论的目的是通过生理和技术的角度,分析这些生物标志物作为预测卵巢反应存在的优势和劣势。

研究者系统性检索最新(到2014年5月为止)的相关文献,并总结了现有的证据。

AMH值和AFC均会受到技术、生理和外源性因素的影响。AMH显示出的一些变化的周期,与卵泡发育的生理作用是一致的。另外还有在药物治疗和病理条件下的影响下增长的数据,除了循环独立测量,都提示AMH作为临床用途是合适的。一系列人工AMH检测的问题可将会能推进全自动检测的发展。尽管描述了AFC测量技术的标准化,AFC是受标记间和内部算子变异影响的,和外部因素的影响可能是相当。在一些专科中心,AFC要求其测量时间为周期的第2和第4天。观察性研究表明AFC 和AMH在预测卵巢反应的高低时是可以相互媲美的,但最近的研究表明,AMH具有明显更好的性能。

AMH和AFC对外源性促性腺激素的卵巢反应预测的性能特点,因单站点观测组被夸大了,由此才认为AMH和AFC表现出相当的性能特点。此次大规模多中心随机对照试验,集中分析性能,表明AMH实际是更准确和更可靠的生物标志物,可能也反映了AFC测定标准化的困难。而AFC也保留一定的优势,特别是即时性和可达性。AMH的国际标准化与稳定的自动检测相结合,很有可能提高其性能,成为预测卵巢反应性的生物标志物的选择。
