Covid 19: Covid-19 does not harm baby’s brain during pregnancy: study


WASHINGTON: Two years after the epidemic, there is evidence that pregnant women are more susceptible to the SARS-CoV-2 virus that causes Covid-19. However, little is known about the potential consequences for an unborn baby if the mother became infected during pregnancy.
The study was presented at the annual meeting of Radiological Society of North America (RSNA).
In pregnant women, mild to moderate Covid-19 has no effect on the developing fetal brain, according to a recent study.
The probability and effect of vertical transmission, meaning the transmission of the virus from mother to fetus, remains unclear.
“Women infected with SARS-CoV-2 during pregnancy are concerned that the virus may affect the development of their unborn child, as is the case with some other viral infections,” said Sophia, senior author of the study. Stocklin, MD from the Department of Radiology at Ludwig Maximilian University of Munich, Germany. “So far, despite a few reports of vertical transmission in the fetus, the exact risk and impact remain largely unclear.
The aim of our study was to bridge this gap in knowledge of the effects of maternal SARS-CoV-2 infection on fetal brain development. ”
Dr. Stoklin and colleagues used the fetus MRI To study 33 patients with covid-19 infection during pregnancy. Patients were approximately 28 weeks into their pregnancy, on average, the onset of symptoms occurs within just over 18 weeks of pregnancy. The most common maternal symptoms were decreased or no sense of smell and taste, dry cough, fever, and difficulty breathing.
The scan was evaluated by two board-certified radiologists with many years of experience in fetal MRI. They found that brain development in the assessed areas was age-appropriate in all fetuses. No signs of fetal brain infection were found.
“In our study, there is no evidence that maternal SARS-CoV-2 infection has any effect on the brain development of the unborn child,” said Dr. Said Stokley. “This fact will help reassure the affected parents.”
Dr. Stokley warned that only mothers with mild to moderate symptoms and no hospitalization were included in the study.
“Since the effects of severe infections on fetal brain development have not been conclusively determined, active protection against SARS-CoV-2 infection during pregnancy remains important,” she said.
As part of that protection, the Centers for Disease Control and Prevention The CDC recommends vaccinations for all people 12 years of age and older, including women who are pregnant or planning to become pregnant. The CDC notes that the vaccine can protect against serious illness.
“Vaccination is by far the most promising protection against covid-19,” said Dr. Said Stokley. “Any potential side effects can also be controlled in pregnant women. Therefore, despite the encouraging results of our study, pregnant women should strongly consider vaccination.”
Researchers will follow patients over the next five years, including a detailed assessment of the newborn as well as an assessment of neurological development.
