Evaluation of Maternal Fetal Outcomes of Pregnant Women and Mothers with Suspected Infection by SARS-CoV-2 Treated at the Municipal Hospital of São Bernardo do Campo (HMU-SBC), Brazil.

Objectives: The impact of Covid-19 infection on pregnancy and perinatal outcomes is not fully known. To describe the risk factors and perinatal outcome of pregnant women with suspected COVID-19 infection. Methods: We evaluated medical records of women with suspected or confirmed SARS-CoV-2 infection who received health care services at the University Hospital of São Bernardo do Campo from March 1 to July 31, 2020, and personal, clinical, and laboratory data of these women and their newborns. Results: Of the 219 women identified, 29% were asymptomatic. Considering the total population, 26% and 17% had obesity and hypertensive syndrome, respectively. Fever measured in the emergency room was the main reason for hospitalization. The presence or not of flu-like symptoms did not impact on perinatal outcomes. Pregnant women requiring hospitalization had newborns with lower birth weight (p < 0.01), shorter length (p = 0.02), and smaller head circumference (p = 0.03), and, in these cases, a higher number of cesarean section deliveries was observed. Conclusion: COVID-19 infection did not affect the prognosis of pregnancy and newborns. However, the worst clinical outcome, requiring hospitalization, had an impact on the anthropometric measurements of newborns. Significance: What is already known on this subject?The SARS-CoV-2 infection is not fully undestood, specially during pregnancy and puerperae. There are conflicted information about this in the literature so far. However, it is known that respiratory infections such as influenza and SARS can develop unfavorably in pregnant women, since pregnancy changes the women's physiological condition, including altered immunity to tolerate placenta and fetus proper development. What this study adds?COVID-19 did not affect the prognosis of pregnancy and newborns in this study, but, the worst clinical outcome (hospitalization), impacted the anthropometric measurements of newborns.
