Outcome of SARS-CoV-2 in pregnancy and newborns-is there a new kid in the TORCH block?

ABSTRACT

Objective. This study aimed to perform a systematic review of existing literature to assess the outcomes of pregnancy in women with COVID-19 infection and their newborns while estimating the possibility of vertical transmission. Materials and methods. We conducted a systematic literature research using Pubmed and Google Schol-ar covering the period from December 2019 to 20th of November 2020. The review was conducted in ac-cordance with PRISMA guidelines. Outcomes. We included 16 studies – systematic reviews and meta-analyses published between May 2020 and November 2020 – which focused on perinatal outcomes of pregnant women with COVID-19 and 7 case reports of neonates with congenital transmission of COVID-19. Overall, the rate of COVID-19 cases in neonates of COVID-19 positive mothers was 3% with 95% CI [1.86, 4.24]). The preterm birth rate was 16.4% with 95% CI [10.5, 22.3] and the rate of stillbirths and foetal deaths was 1.4% (11 studies, 0 to 4.8%). From the 7 newborns with proved vertical transmission, majority were born preterm, with good birth weight and APGAR score and heterogenous symptoms;4 developed severe symptoms. Overall progress and evolution for both mother and newborn was good. Conclusions. COVID-19 impact on pregnancy outcome is similar to general population in regard to preterm rate and stillbirth rate. Vertical transmission is possible and it seems to occur in about 3% of cases. Overall maternal and perinatal outcome is favourable and clinical presentation of in utero transmission of SARS-CoV-2 in newborns is heterogenous. © 2021, Amaltea Medical Publishing House.
