项目摘要

Congenital Cytomegalovirus (CMV) infection is a leading cause of birth defects and developmental disabilities in the U.S., affecting thousands of children each year. Notably, the majority of children acquire congenital CMV from non-primary maternal CMV infection rather than primary infection. Thus, determining the maternal serostatus in the field may further our understanding of the association between CMV infection status and worse pregnancy outcome, and risk stratify pregnant women during gestation. Current methods to detect maternal CMV serostatus are labor intensive and require sophisticated equipment, dedicated laboratory space, and trained technicians. We propose developing a point-of-care (POC) test for rapid screening of maternal CMV serostatus. A rapid, on-site test for CMV serostatus screening in biospecimens would: (1) allow for immediate counseling and confirmatory testing, and (2) avoid having to create new laboratory infrastructure for biospecimen testing. Alternatively, a rapid POC test that could be utilized during initial study screening visits would permit the efficient identification and enrollment for CMV vaccine testing.

先天性巨细胞病毒 (CMV) 感染是美国出生缺陷和发育障碍的主要原因，每年影响数千名儿童。值得注意的是，大多数儿童获得先天性 CMV 的原因是非原发性母体 CMV 感染，而不是原发性感染。因此，现场确定孕产妇血清状态可能会进一步了解 CMV 感染状态与较差妊娠结局之间的关联，并对妊娠期间的孕妇进行风险分层。目前检测母体巨细胞病毒血清状态的方法是劳动密集型的，需要精密的设备、专用的实验室空间和训练有素的技术人员。我们建议开发一种护理点 (POC) 测试来快速筛查母体 CMV 血清状态。对生物样本中 CMV 血清状态筛查进行快速现场测试将：（1）允许立即咨询和确认测试，（2）避免为生物样本测试创建新的实验室基础设施。或者，可以在初始研究筛选访问期间使用快速 POC 测试，以便有效识别和登记 CMV 疫苗测试。
