Mild to moderately severe COVID-19 in pregnant women does not appear to affect the developing fetal brain, according to a study presented today at the Radiological Society of North America (RSNA) Annual Meeting. ..

Two years after the pandemic, there is evidence that pregnant women are more vulnerable to the SARS-CoV-2 virus that causes COVID-19. However, little is known about the possible consequences for the foetation if the mother is infected during pregnancy. The potential and effects of vertical transmission, the passage of the virus from the mother to the foetation, remain unknown.

“Women infected with SARS-CoV-2 during pregnancy, like others, are concerned that the virus can affect fetal development. Virus infectionSophia Stoclain, MD, Ph.D., Principal Investigator, Department of Radiology, Ludwig Maximilian University, Germany, said: not clear. The purpose of our study was to fill this gap in knowledge about the effects of maternal SARS-CoV-2. infection on Fetal brain development.. “

Dr. Stöcklein and colleagues used fetal MRI to study 33 patients with COVID-19 infection during pregnancy. Patients were on average about 28 weeks pregnant. Onset of symptoms It occurs on average over 18 weeks after becoming pregnant. The most common maternal symptoms were loss or loss of smell and taste, dry cough, fever, and shortness of breath.

Two board-certified radiologists with several years of experience in fetal MRI evaluated the scan.They are Brain development In the assessed areas, all foets were age-appropriate. There were no findings indicating an infection in the fetal brain.

“In our study, there was no evidence that maternal SARS-CoV-2 infection had any effect on brain development. Foetation“This fact should help reassure affected parents,” said Dr. Stöcklein.

Dr. Stöcklein warned that only mothers who had mild to moderate symptoms and were not hospitalized were included in the study.

“Active protection against SARS-CoV-2 infection during pregnancy remains important, as the effects of severe infections on fetal brain development have not been definitively determined,” she said.

As part of its protection, the Centers for Disease Control and Prevention (CDC) recommends vaccination for all people over the age of 12, including women who are pregnant or thinking of becoming pregnant. The CDC states that vaccines can protect against serious illness.

“So far, vaccination is the most promising defense against COVID-19,” said Dr. Stöcklein. “Even in pregnant women, potential side effects are manageable. Therefore, despite the promising results of our study, Pregnant female Vaccination should be strongly considered. “

Researchers will follow patients over the next five years, including detailed neonatal and neurological development assessments.
