Objectives: This study aimed to summarize the clinical features, maternal, fetal, and perinatal outcomes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) proven infections of pregnancies.
Material and methods: This retrospective single center study was conducted on 75 pregnant patients diagnosed of coronavirus disease 2019 (COVID-19). Demographic characteristics, clinical courses, laboratory and radiological findings, and maternal and perinatal outcomes were analyzed using medical records.
Results: Of the 75 pregnant women infected with COVID-19, 49 had mild infections. The most common initial symptoms were myalgia (61.4%), cough (57.9%), headache (50.9%), and dyspnea (49.1%). More than half of the patients (57.3%) on admission were in their third trimester. Three patients had pre-existing chronic illnesses (hypothyroidism, asthma and rheumatoid arthritis) and three patients had gestational diabetes. There were two cases admitted to intensive care unit, one of whom was due to COVID-19 infection. No maternal mortality was recorded. The mode of delivery was a cesarean section in 20 cases among the 35 labors. Six gestations ended in a miscarriage and 11 women gave birth prematurely. One stillbirth occurred at the 38th week of gestation. Among 37 neonates, 14 necessitated admission to neonatal intensive care unit. Neonatal mortality, congenital malformation, and mother to child transmission were not seen in the newborns.
Conclusions: The results of our study suggest that the clinical course of COVID-19 infection in pregnant women was mostly asymptomatic/mild. There was also no evidence of vertical transmission of COVID-19 infection.
