Abstract

Background: The novel coronavirus disease 2019 (COVID-19) was more devastating in people with comorbidities such as advanced age and immunodeficiency. Another group affected by COVID-19 was pregnant women. Immunological changes during pregnancy and conditions such as gestational diabetes and pre-eclampsia that occur during pregnancy also have effects on the fetus. The aim of this study was to analyze the effects of PCR-proven COVID-19 infection during pregnancy on fetus and newborn. Methods: Between December 2019 and October 2021, data from pregnant women with COVID-19 symptoms or a history of contact with people with COVID-19, infected with PCR-proven COVID-19 virus, were analyzed retrospectively. Clinical and laboratory data of pregnant women were analyzed. Death data associated with COVID-19 were evaluated. Clinical and laboratory findings of newborns related to COVID-19 and mortality data related to COVID-19 were recorded. The study received approval from the Gazi Yasargil Training and Research Hospital ethics committee (09.07.2021/853). Results: We evaluated 327 pregnant women who were followed up in our hospital and whose deliveries ended in live birth, stillbirth, miscarriage, or curettage. One hundred eighty-five (56.6%) of the pregnant women had at least one COVID-19-related symptom. We evaluated the data of 306 live births, 21 intrauterine fetal deaths, and 13 postnatal deaths. Among the postnatal deaths, five infants succumbed directly due to COVID-19 infection. A total of 23 live-born babies (7.5%) were classified as small for gestational age (SGA), while 80 babies (26.1%) were born before 37 weeks of gestation, and 32 babies (10.4%) were born before 32 weeks. Cord blood gas analysis revealed that 19 infants (6.3%) had pH < 7 and base excess (BE) < -12. The rate of perinatal asphyxia was significantly higher in babies born to mothers who did not survive (p = 0.027). A considerable number of infants, 119 (40.3%), were admitted to the neonatal intensive care unit (NICU). Among the seven infants with positive PCR results admitted to the NICU, five (4.2%) did not survive. Conclusion: While COVID-19 infection in pregnancy seriously affects mortality and morbidity in pregnant women, it also causes mortality and morbidity on the fetus.
