Maternal and Neonatal Outcomes in Pregnant Women With SARS-CoV-2 Infection Complicated by Hepatic Dysfunction.

Abstract

Background and objectiveThe coronavirus disease 2019 (COVID-19) pandemic has caused one of the most devastating healthcare crises in recent times and presented many diagnostic challenges and uncertainties. COVID-19 complicated by acute hepatic dysfunction is a well-described phenomenon, but its impact on maternal and perinatal outcomes is not well documented. In this study, we aimed to evaluate the maternal and neonatal outcomes in pregnant women with COVID-19 complicated by liver dysfunction and compare those with pregnant women with COVID-19 and normal liver function.MethodologyThis was a retrospective observational cohort study conducted at the Tata Main Hospital, Jamshedpur, a tertiary care hospital in eastern India. All COVID-19-positive pregnant women (n=249) admitted to the hospital from May 15, 2020, to August 15, 2021, were included in this study. Retrospective data collection was done using the medical records of these COVID-19-positive pregnant women and included the baseline characteristics, past medical history, obstetric history, clinical presentation, laboratory results, management modalities, and maternal and neonatal outcomes. Of note, 107 women were found to have acute liver function abnormality on admission and 142 women had normal liver function tests (LFTs). Pregnant women with normal LFTs were classified as group one and those with deranged LFTs as group two. Characteristics such as age, period of gestation, symptoms, associated comorbidities, laboratory results, management, and outcomes were compared across both groups.ResultsOut of the total 249 pregnant women with COVID-19 admitted during the study period, 42.97% (n=107) women had laboratory findings consistent with liver dysfunction and 142 women (57.03%) had a normal liver function. Significantly higher levels of lactate dehydrogenase (LDH), C-reactive protein (CRP), neutrophil-lymphocyte ratio (NLR), alanine transaminase (ALT), aspartate aminotransferase (AST), and total bilirubin levels were seen in pregnant women with hepatic dysfunction when compared to those with normal liver function. Among the 249 patients, the majority were asymptomatic or had mild disease, 12 women had moderate disease, and six women had severe COVID-19. All women with severe COVID-19 had deranged LFTs. There was no statistical difference in terms of obstetric management between pregnant patients with and without liver dysfunction. Out of the 107 women with deranged liver function, 18 women had a preterm birth, four had intrauterine fetal death, and one had neonatal death. Complications such as postpartum hemorrhage, the need for blood transfusions, sepsis and multiorgan failure, and mortality were more commonly seen in the group of pregnant women with hepatic dysfunction associated with COVID-19.ConclusionCOVID-19 in pregnancy may cause deranged LFTs in these women. Pregnant women with COVID-19 complicated by liver dysfunction have been reported to have worse inflammation, higher disease severity, and more morbidity and mortality when compared to those without liver dysfunction. They are also at a higher risk of complications such as postpartum hemorrhage, the need for blood transfusion, sepsis, and multiorgan dysfunction.
