1080. Clinical Characteristics and Outcomes of 104 Pregnant Women with Coronavirus Disease 2019 during delta wave; single-center observational study


 
 
 Pregnancy is one of the risk factor associated with the severity of Coronavirus Disease 2019 (COVID-19). The perinatal complications also known to be increased when pregnant women become infected with COVID-19. However, there were not enough studies involving pregnant women with severe COVID-19, especially in Korea. The purpose of this study was to analyze the cases of pregnant women with COVID-19 infection with various severities, and to compare and describe the clinical course and the effects on pregnancy and perinatal prognosis according to severity.
 
 
 
 We retrospectively analyzed the medical records of adults 18 years of age or older who were PCR-confirmed COVID-19 and proved pregnancy, from February 1, 2020 to January 31, 2022. Through the epidemiological investigation report, the patient's medical history, obstetric history, date of diagnosis and variants of COVID-19, and vaccination history were collected. Clinical symptoms, oxygen demand, chest imagings, treatment, perinatal complications, fetal conditions, delivery results, and complications were collected through medical records.
 
 
 
 A total of 104 pregnant women with PCR-confirmed COVID-19 were hospitalized. The age at the time of diagnosis was 33 ±4.24 (Mean ± SD) years, and 4 patients (3.8%) were vaccinated with the COVID-19 vaccine. During hospital stay, the most common complaints were cough (99 patients, 95.2%) and fever (85 patients, 81.7%). Oxygen was applied in 40 patients (38.5%), and in 19 patients (18.3%) in severe cases. Thirty-seven patients (35.6%) delivered during isolation treatment. Critical COVID-19 patients group has statisticaly significant higher rate of preterm delivery compared with mild COVID-19 patient group (31.6 % versus 6.3 %, p=0.009). One patient died from septic shock caused by multidrug-resistant Acinetobacter baumannii during treatment. A total of 39 babies were born, of which 4 received postnatal oxygen therapy.
 
 
 
 Pregnant women with COVID-19 had higher mortality rates, aggravation rates, and premature birth rates compared to non-pregnant patients of the same age. In a situation where effective and safe COVID-19 treatments for pregnant women are limited, it is necessary to increase the vaccination rate to prevent undesired outcomes in both mother and child.
