Abstract

Restricted data on the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reactive IgG antibodies by breast milk to infants, born to mothers who did not know if they had coronavirus disease 2019 (COVID-19), are presented. The objective of the present work was to demonstrate the existence of specific IgG antibodies against the SARS‐CoV‐2 virus in the milk of breastfeeding mothers in the suburban area of Şanlıurfa, Türkiye. This retrospective analysis examined the medical records of maternal and neonatal data for all 51 newborns to 50 mothers from September to October 2020. The present work was approved by the local medical ethics committee. Written informed consent was obtained from the mothers. Testing SARS-CoV-2 reactive IgG was performed using ELISA assay. SARS-CoV-2 reactive IgG were detected in 58% of breast milk. Over the past year, SARS-CoV-2 reactive IgG identified in breast milk of mothers without symptoms of viral respiratory infection (self-reported diagnosis) was 12.5 times lower than mothers with symptoms. The IgG responses were different between symptomatic and asymptomatic mothers’ and infants’ samples. These results propose that along with the COVID-19 pandemic, breastfeeding could be safe, and the existence of SARS-CoV-2-reactive IgG antibodies in breast milk could provide passive immunity to breastfed infants, and keep them safe against COVID-19 infection.
母乳中是否存在针对严重急性呼吸综合征冠状病毒2 (SARS-CoV-2)的反应性IgG抗体?
本文介绍了不知道自己是否患有2019年冠状病毒病(COVID-19)的母亲所生的婴儿通过母乳传播严重急性呼吸综合征冠状病毒2 (SARS-CoV-2)反应性IgG抗体的限制性数据。本研究的目的是证明在Şanlıurfa、基基耶郊区母乳喂养的母亲的乳汁中存在针对SARS - CoV - 2病毒的特异性IgG抗体。这项回顾性分析检查了2020年9月至10月期间所有51名新生儿和50名母亲的孕产妇和新生儿数据的医疗记录。本研究得到了当地医学伦理委员会的批准。获得了母亲的书面知情同意。ELISA法检测SARS-CoV-2反应性IgG。在58%的母乳中检测到SARS-CoV-2反应性IgG。在过去一年中,在没有病毒性呼吸道感染症状(自我报告诊断)的母亲的母乳中发现的SARS-CoV-2反应性IgG比有症状的母亲低12.5倍。有症状和无症状母亲和婴儿的IgG反应存在差异。这些结果表明,随着COVID-19大流行,母乳喂养可能是安全的,母乳中存在的sars - cov -2反应性IgG抗体可以为母乳喂养的婴儿提供被动免疫,并使他们免受COVID-19感染。
