Pregnancy Outcomes in Women With SARS-CoV-2 Infection During the First and Second Waves of the COVID-19 Pandemic in a Tertiary Care Hospital in Ayodhya, Uttar Pradesh, India: A Comparative Study

Introduction Pregnancy is an altered immunological state and not necessarily an immune-compromised state. These immune changes subject pregnant women to increased susceptibility to infection. During the coronavirus disease 2019 (COVID-19) pandemic, pregnant women were more susceptible to serious illness for reasons other than their immune response. The purpose of this study was to compare the feto-maternal outcome (morbidity and mortality) in relation to pre-existing maternal co-morbidities, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection-related disease severity, and its impact on the mode of delivery and long-term sequelae in pregnant women in the first and second waves of the COVID-19 pandemic. Materials and methods This was a hospital-based comparative study carried out on 101 pregnant patients during the first wave (April 2020 to December 2020) and 22 patients in the second wave (March 2021 to July 2021) of the COVID-19 pandemic, in Rajashri Dashrath Autonomous State Medical College, Ayodhya, India. All pregnant women with COVID-19 in the first and second waves were included. Non-pregnant patients with COVID-19 infection, pregnant patients lost to follow-up, pregnant patients without COVID-19 infection, and patients in the puerperal period were excluded. Results Seventy-three (72.27%) patients in the first wave and 12 (54.54%) in the second wave were asymptomatic. Those with mild disease numbered 20 (25.74%) in the first wave and six (27.27%) in the second wave. Disease severity was more in the second wave, that is four (18.18%) as compared to one (0.99%) in the first wave. Severe anemia was the most common co-morbidity associated with both first (n=4, 3.96%) and second (n=5, 22.72%) waves. Four (6.45%) spontaneous abortions occurred in the first wave as compared to three (20%) in the second wave. Intensive care unit (ICU) admission was more in the second wave (n=4, 26.66%) as compared to the first wave (n=1, 1.61%). Two (13.33%) maternal deaths occurred in the second wave and none in the first wave. Cesarean sections in both the first and second waves were performed for obstetric indications only. No newborns tested positive in the COVID-19 reverse transcription-polymerase chain reaction (RT-PCR) in the first and second waves at the time of birth; however, three (4.83%) tested positive on day five of birth in the first wave. Fever was the most common presentation in newborns; seven (11.26%) in the first wave and three (20%) in
