Abstract
Aim: To evaluate perinatal outcomes regarding clinical presentation in pregnancy and the vertical transmission potential of COVID-19.
Methods: Clinical records, laboratory findings, and chest computed tomography (CT) scans were retrospectively reviewed from 20 pregnant patients with laboratory-confirmed COVID-19 who were admitted to Renmin Hospital of Wuhan University and The Third Hospital of Wuhan, from Jan 20 to Mar 16, 2020, including three in the first-trimester, two in the second-trimester, and 15 in the third-trimester. Evidence of vertical transmission was assessed by testing for neonatal throat swab samples. The pathological changes of COVID-19 on the placenta is evaluated by hematoxylin-eosin staining.
Results: The most common symptoms of the pregnant women with SARS-CoV-2 infection were fever and cough, which is comparable to the nonpregnant adults with COVID-19 infection. Nobody was transferred to intensive care unit (ICU) for treatment and there were no maternal and neonatal deaths. However, there was one case with induced abortions on first-trimester (due to pregnant woman’s concerns about COVID-19), one diagnosed with ectopic pregnancy, no intrauterine fetal deaths during the study period. Delivery occurred in 15 patients in the third trimester. Their incidence of preterm birth was 20%. Three of the four preterm births were spontaneous. The average length of stay was 20.77 days. No neonatal SARS-CoV-2 infection was detected. There were two placentas found with acute chorioamnionitis, one showed normal placenta morphology.
Conclusion: In this case series study, COVID-19 had no short-term adverse effect on pregnant women except premature birth. The vertical transmission of SARS-CoV-2 did not occur in our study.
