Clinical outcomes of maternal and neonate with COVID-19 infection – Multicenter study in Saudi Arabia

摘要

Background To this end, the influence of COVID-19 on pregnant women and their neonates is not completely clear. Therefore, the main aim of this study is to investigate maternal and neonatal clinical outcomes with confirmed COVID-19 infection. Besides, it investigates the likelihood of vertical transmission of COVID-19 infection from pregnant women to their neonates. Methods A retrospective descriptive study was conducted in three medical centers during the period from March to November 2020. Data were collected from the available medical records in the respective hospitals using a standardized questionnaire on maternal and neonatal clinical outcomes. All pregnant women with confirmed COVID-19 infection across the three hospitals and their neonates were eligible to participate in this study. Descriptive statistics were presented as a median and interquartile range (IQR) or frequencies and percentages as appropriate using SPSS 24.0 software. Results This study has identified a total of 288 pregnant women with confirmed COVID-19 infection over the study period of a median age of 30 years and median GA at diagnosis 38 weeks (IQR: 39 -33) as well as 27% of them were obese ( n = 78). The majority of pregnant women were symptomatic with cough ( n = 92, 31.9%) being the most frequent COVID-19 symptom followed by fever and dyspnea ( n = 36, 12.5%). Two-hundred and four pregnant delivered (70.84%) and caesarean sections were prevalent among 35.8% of them. The most common adverse pregnancy outcome was premature ( n = 31, 15.5%), followed by fetal distress ( n = 13, 6.5%), preeclampsia ( n = 4, 2.0%), and one pregnant woman died. The laboratory results exhibit that temperature higher than 38 ( n = 27), leukopenia ( n = 19), neutropenia ( n = 54), ALT ( n = 12), AST ( n = 31), and thrombocytopenia ( n = 35) were less frequent among pregnant women while lymphopenia ( n = 126), hemoglobin levels lower than 13.0 ( n = 218), deceased albumin levels ( n = 195) were most frequent among them. However, a small proportion of pregnant women were admitted to the ICU (3.8%). The most frequent maternal treatments were antibiotics ( n = 81), antiviral ( n = 49), and corticosteroid ( n = 24). Of 204 neonates, four had died and all the remaining neonates were alive. The median gestational age at delivery was 39 weeks (IQR: 35–40). Most neonates had normal laboratory results. However, 14 had lymphopenia (7.0%), 22 had neutropenia (11.0%), and 11 had thrombocytopenia (5.5%). Four infants had low hemoglobin levels of less than 13.0 (2.0%) and 81 had hyperbilirubinemia (e.g., total bilirubin of higher than 23; 40.5%). Approximately less than one-half of neonates required admission to the NICU ( n = 86, 43%), 7% of them required respiratory support of mechanical ventilation, and none of them get infected with COVID-19 disease. Conclusion This multicenter study suggests that the majority of pregnant women had mild or moderate disease symptoms. Nevertheless, this study did not find any evidence of possible vertical transmission of COVID-19 infection from mothers to their babies. This study may provide a baseline for further studies focusing on investigating long-term maternal and neonate's outcomes and possible vertical transmission of COVID-19 from mothers to their newborn babies.
