Maternal-Fetal Characteristics of Pregnant Women With Severe COVID Disease and Maternal-Neonatal Characteristics of Neonates With Early-Onset SARS-CoV-2 Infection: A Prospective Data Analysis.

Introduction COVID-19 and its mutants have significantly impacted the health care system, claiming numerous lives and adding to the morbidity. The data are scarce to describe the effect of disease severity on pregnancy outcomes, the possibility of mother-to-child transmission, and neonatal outcomes of COVID-positive babies. This study aimed to report the maternal and fetal characteristics of pregnant women with severe COVID disease as well as maternal and neonatal characteristics of neonates with early-onset SARS-CoV-2 infection. Materials and methods This is a prospective data analysis of pregnant women with severe COVID disease and neonates with early-onset SARS-CoV-2 infection. The disease parameters including demographic data, clinical presentation, investigations, management, and maternal and neonatal outcomes were recorded and analyzed. Results India has faced three waves till now. At the study center, a total of 165 (60, 68, and 37 in the first, second, and third waves, respectively) COVID-positive pregnant women were admitted during all three waves. No severe COVID disease with pregnancy was noted in the first and third waves. During the second wave (March to June 2021), 15 pregnant women were found to have severe COVID disease. All of them had COVID-related symptoms, with the majority requiring supplementary oxygen at presentation. Nine of these women had intrauterine fetal demise at admission. Nearly 73% were in their second trimester, and the rest were in the third trimester. There was raised total leukocyte count and alanine transaminase in 73% and raised aspartate transaminase in all cases. All of them were admitted to the intensive care unit. Two women in their third trimester had a termination of pregnancy by cesarean section, and one of the neonates had early neonatal death due to perinatal asphyxia. Both the neonates were COVID-19 positive. Eleven women with critical illness succumbed to the disease. No neonate was found to have early-onset SAR-CoV-2 infection during the first and third waves. Only 11 neonates tested positive for SARS-CoV-2 at the time of birth during the second wave. None of them had any COVID-related symptoms. Preterm birth was reported in four cases. The average Apgar scores at 1 and 5 minutes were 6.9 and 8.09, respectively. The average birth weight was 2,551.81 grams. All neonates were initially kept in the neonatal intensive care unit. Out of 11, four neonates required treatment in the form of positive-pressure ventilation, chest compressions, high-flow nasal oxygen, and non-invasive and invasive ventilation. Neonatal mortality was documented in two cases. Six mothers had one or more positive results in either amniotic fluid, placental membrane, or vaginal or cervical swab, highlighting the possibility of antepartum or intrapartum transmission. Conclusion Severe COVID disease during pregnancy was associated with high rates of intrauterine fetal demise and maternal mortality. Raised liver enzymes might be taken as a predicting factor for severe disease. On the other hand, early-onset neonatal SARS-CoV-2 infection is mostly asymptomatic and has a good prognosis. Additionally, mother-to-child transmission of SARS-CoV-2 is possible in the antepartum and intrapartum periods.
