Abstrakt: Our aim was to investigate whether SARS-CoV-2 infection raised high risks of late pregnancy complications, and posed health problems in fetuses and neonates. We analyzed the data of COVID-19 pregnant women with COVID-19 during late pregnancy and their neonates. Eleven out of 16 (69%) pregnant women with COVID-19 had ++ or +++ of ketone body in urine. The blood uric acid of pregnant patients was 334 μmol/L (IQR, 269–452). D-dimer and FDP in pregnant patients were 3.32 mg/L (IQR, 2.18–4.21) and 9.6 mg/L (IQR, 5.9–12.4). Results of blood samples collected at birth showed that 16 neonates had leukocytes (15.7 × 109/L (IQR, 13.7–17.2)), neutrophils (11.1 × 109/L (IQR, 9.2–13.2)), CK (401 U/L (IQR, 382–647)), and LDH (445 U/L (IQR, 417–559)). Twenty-four hours after birth, a neonate from COVID-19 woman had fever and positive of SARS-CoV-2 gene. Another woman had strongly positive for SARS-CoV-2 gene (+++) for 4 weeks, and delivered one neonate who had SARS-CoV-2 IgM (46 AU/mL) and IgG (140 AU/mL) on day 1 after birth. In the third trimester, COVID-19 infection in pregnant patients raised high risks of ketonuria, hypercoagulable state, and hyperfibrinolysis, which may lead to severe complications. COVID-19 increased the inflammatory responses of placenta, and fetuses and neonates had potential organ dysregulation and coagulation disorders. There was a potential intrauterine transmission while pregnant women had high titer of SARS-CoV-2, but it is necessary to detect SARS-CoV-2 in the blood cord, placenta, and amniotic fluid to further confirm intrauterine infection of fetuses.
