Clinical Presentation and Outcomes of Pregnant Women With Coronavirus Disease 2019: A Systematic Review and Meta-analysis

BACKGROUND: Descriptions of coronavirus disease 2019 (COVID-19) have focused on the nonpregnant adult population. This study aims to describe the clinical characteristics and perinatal outcomes of COVID-19 in pregnancy. METHODS: We searched databases from December 2019 to 30 April 2020. Eligible studies reported clinical characteristics, radiological findings, and/or laboratory testing of pregnant women during infection. Data were pooled across studies using a random-effects model. RESULTS: Twenty-four studies (136 women) were included. The most common symptoms were fever (62.9%) and cough (36.8%). Laboratory findings included elevated C-reactive protein (57%) and lymphocytopenia (50%). Ground-glass opacity was the most common radiological finding (81.7%). Preterm birth rate was 37.7% and cesarean delivery rate was 76%. There was 1 maternal death. There were 2 fetal COVID-19 cases. CONCLUSIONS: The clinical picture in pregnant women with COVID-19 did not differ from the nonpregnant population; however, the rate of preterm birth and cesarean delivery are considerably higher than international averages.
