NEJM: 无症状比例达87.9%!纽约长老会艾伦医院孕产妇新冠病毒检测

2020年4月13日,哥伦比亚大学欧文医学中心/纽约长老会艾伦医院的Desmond Sutton等人发表在《新英格兰医学杂志》(NEJM)上的一篇CORRESPONDENCE中称,该院对215名孕产妇进行新冠病毒PCR检测结果显示,有15.3%的孕妇呈阳性,且87.9%的确诊患者没有表现COVID-19相关症状。

近几周来,COVID-19在纽约市迅速传播开来。在这场大流行期间,产科人群面临着一个独特的挑战,因为这些患者与医疗保健系统有着多重互动,最终大多数患者被送进医院分娩。Desmond Sutton及其同事自从2020年3月13日首次在一名孕产妇中诊断COVID-19之后,也分享了孕产妇合并COVID-19的早期经验,包括两名最初无症状的妇女在分娩后检测出SARS-CoV-2阳性。此后,该院即对收治孕产妇进行鼻咽拭子的病毒PCR检测以排查有无感染。

在2020年3月22日至4月4日期间,共有215名孕产妇在哥伦比亚大学欧文医学中心/纽约长老会艾伦医院(New York-Presbyterian Allen Hospital and Columbia University Irving Medical Center)分娩。所有孕产妇在入院时都进行了COVID-19症状的筛查。4名孕产妇(1.9%)入院时出现发热或其他COVID-19症状,且这4名孕产妇SARS-CoV-2检测均呈阳性(图1)。在211名没有症状的妇女中,入院时都没有发烧。211名无COVID-19症状的妇女中,210名(99.5%)获得了鼻咽拭子,其中29名(13.7%)呈SARS-CoV-2阳性。33例SARS-CoV-2阳性患者中有29例(87.9%)在入院时无COVID-19症状。

在29名无症状但入院时呈SARS-CoV-2阳性的妇女中,有3名(10%)在产后出院前(中位住院时间,2天)出现发热。其中两名患者接受了假定为子宫内膜炎的抗生素治疗(尽管1名患者没有局部症状),1名患者由于COVID-19被假定为发热并接受了支持治疗。一名患者入院时鼻咽拭子SARS-CoV-2呈阴性,产后出现症状;在初次检测呈阳性后3天重复进行SARS-CoV-2检测。

该中心对所有分娩的孕妇进行了SARS-CoV-2的常规检测,结果显示在纽约大流行期间,该单中心的孕产妇SARS-CoV-2阳性达15.3%(33/215),且大多数(29/33)SARS-CoV-2阳性的孕产妇为无症状患者。在8例无症状患者中,有1例以上在分娩室就诊。尽管这种流行率对感染率较低的地理区域的推广有限,但它强调了无症状产科患者的COVID-19风险。此外,由于SARS-CoV-2检测还存在一定假阴性结果的比例,因此感染的真实流行率可能被低估。

作者最后强调,对孕产妇进行常规的核酸检测以确定其COVID-19状态,有助于医院采取隔离措施和床位分配、通知新生儿护理和指导个人防护设备。在这个充满挑战的时期,获取这些临床数据为保护母亲、婴儿和医疗团队提供了一个重要的机会。
