  一项英美联合研究显示,胎儿期暴露于丙戊酸盐与6岁时认知功能下降存在剂量依赖的相关性。论文1月23日在线发表于《柳叶刀神经病学》(Lancet Neurol)杂志。

  研究纳入1999年10月至2004年2月间患癫痫并接受抗癫痫药单药治疗(卡马西平、拉莫三嗪、苯妥英或丙戊酸盐)的妊娠女性305例,以及311名子女(包括6对双胞胎)。

  结果为,多变量分析提示,胎儿期暴露于丙戊酸者,6岁时IQ较低(平均为97),暴露于卡马西平、拉莫三嗪或苯妥英者,6岁时IQ分别为105、108和108。与暴露于其他抗癫痫药者相比,暴露于丙戊酸盐者在语言和记忆能力方面表现较差,且在非语言和执行功能方面亦较暴露于拉莫三嗪者差。

  大剂量丙戊酸盐与IQ(P<0.0001)、语言能力(P=0.0045)、非语言能力(P=0.0028)、记忆力(P=0.0434)和执行功能(P=0.0004)呈负相关,但暴露于其他抗癫痫药则不然。6岁时IQ 水平不仅与幼年时IQ水平相关,还受胎儿期暴露于抗癫痫药物的影响。与标准样本相比,胎儿期暴露于抗癫痫药儿童右利手较少(P=0.0404),且在拉莫三嗪和丙戊酸盐组更少。胎儿期暴露于抗癫痫药儿童总体语言能力较非语言能力差,拉莫三嗪和丙戊酸盐组亦如此。围妊娠期服用叶酸女性后代的IQ较未服用叶酸女性后代为高(108对101,P=0.0009)。

Lancet Neurol:丙戊酸盐暴露与儿童认知功能减退相关

  美国学者的一项研究表明,胎儿期丙戊酸盐暴露与儿童6岁时各认知域功能减弱具有剂量相关性。抗癫痫药物暴露诱导的大脑单侧化改变可能是儿童使用右手习惯和语言(和非语言)能力减弱的原因。论文于2013年1月23日在线发表于《柳叶刀·神经病学》(Lancet Neurology)。   此项前瞻性、单盲、多中心、观察性研究在初始分析中共纳入305例伴癫痫母亲和311例儿童(6对双胞胎)。受试母
