Comparison of cases with and without acute liver injury in pregnant women with SARS-CoV-2 infection; obstetric and neonatal outcomes

Background and objective: The effect of SARS-CoV-2 infection on the liver during pregnancy and the impact of SARS-COV-2-related liver injury during pregnancy on obstetric and neonatal outcomes are not yet clear. The aim of this study was to determine the clinical features of pregnant women at risk of liver injury and to investigate the effect of liver dysfunction on obstetric and perinatal outcomes. Methodology: Pregnant women who were followed up and treated at Selcuk University Medical Faculty Hospital and diagnosed with COVID-19 were determined retrospectively. All pregnant women whose PCR test results were positive between March 1, 2020 and July 31, 2022 were included. A total of 96 PCR positive pregnant women were included in the study. The patients were divided into two groups as those with and without liver damage. Both groups were compared in terms of obstetric and neonatal outcomes. Results: While liver damage findings were observed in 34.4% of the 96 pregnant included in the study; No liver damage was observed in 65.6% of the patients. White blood cell, neutrophil, ferritin, D-dimer, troponin, C-reactive protein, systemic immune-inflammation index, interleukin-6, alanine aminotransferase, aspartate aminotransferase and lactate dehydrogenase levels were higher in patients with liver injury compared to pregnant women without liver injury. Prematurity, premature rupture of membranes, preterm premature rupture of membranes, preeclampsia and fetal death were observed relatively more in the patient group with liver injury, there was no statistical significiant difference between the groups in terms of these complications. Unfortunately, maternal death occurred in four mothers with liver injury and in one patient without liver injury. Birthweight, APGAR scores and obstetric complication rates were similar between two groups. Conclusion: Our study showed that pregnant patients with liver damage had worse inflammatory response than those without liver damage. Women with elevated liver enzymes tend to have severe disease, but obstetric and perinatal outcomes were similar between groups with and without liver damage.
