JCEM:脐带血全氟烷基物质与脂质的关系

2019-09-20 xing.T MedSci原创

由此可见,该研究支持以前的证据表明PFAS暴露与改变的脂质谱之间存在关联,并增加了脐带血与未充分研究的PFAS和PFDS之间关系的新信息。

全氟烷基物质(PFAS)是9月11日世界贸易中心(WTC)崩溃期间被怀疑释放的各种持久性有机污染物之一。有证据表明PFAS可能具有心脏代谢效应,包括脂质谱的改变。近日,内分泌和代谢性疾病领域权威杂志Journal of Clinical Endocrinology & Metabolism上发表了一篇研究文章,该研究评估了产前暴露于世贸中心灾难的人群脐带PFAS与脂质之间的关系。

研究人群为222名2001年12月13日至2002年6月26日期间在世贸中心附近医院注册的哥伦比亚大学WTC出生队列的孕妇。研究人员评估了五种脐带血PFAS(全氟辛烷磺酸(PFOS)、全氟辛酸(PFOA)、全氟己烷磺酸(PFHxS)、全氟壬酸(PFNA)和全氟癸烷磺酸盐( PFDS))和脐带血脂质指标(总脂质、总胆固醇和甘油三酯)。

PFAS中对于PFOS、PFOA、PFNA、PFHxS和PFDS的浓度中位数(四分位数间距(IQR))分别为6.32(4.58-8.57)、2.46(1.77,3.24)、0.38(0.25,0.74)、0.66(0.48,0.95)和0.11(0.09,0.16)ng/mL。脂质中总胆固醇的中位数(IQR)为59.0(51.5,68.5)mg/dL,总脂质为196.5(170.5,221.2)mg/dL,甘油三酯为33.1(24.2,43.9)mg/dL。在完全调整的模型中,几种PFAS与较高的脂质水平相关,包括甘油三酯与PFOA和PFHxS之间强烈线性趋势的证据。

由此可见,该研究支持以前的证据表明PFAS暴露与改变的脂质谱之间存在关联,并增加了脐带血与未充分研究的PFAS和PFDS之间关系的新信息。
