Covid infection may harm pregnant women’s fetuses: study

Health & FitnessCovid infection may harm pregnant women's fetuses: study

Fetuses and placentas of pregnant women, especially infected women COVID-19 Early in the epidemic, there was a higher risk of experiencing growths or vascular lesions in the limbs and brain, according to a new study.

According to the research, the results show that the different strains of the virus that emerged during the pandemic caused varying degrees of damage, which was particularly high among those involved in pre-Omicron variants. Research suggests that both the development and health of some unborn babies affected by umbilical cord injury may be potentially compromised.

Using prenatal magnetic resonance imaging, a group of researchers from the Medical University of Vienna, Austria, examined the placentas and fetuses of women who tested positive for SARS-CoV-2 during pregnancy, the study said. Test positive.

The research was published in the journal The Lancet Regional Health – Europe. Although such damage is more frequent and less severe with the currently circulating Omicron subspecies, the study authors still advocate early detection measures for pregnant women who test positive for the coronavirus. Do the test.

Unlike previous studies, in which SARS-CoV-2-related abnormalities were identified only after birth and/or by histopathological methods, the research team focused on prenatal imaging findings, the study found. said

Using prenatal magnetic resonance imaging (MRI), 76 scans of the placenta and fetuses of pregnant women were performed: 38 after confirmed SARS-CoV-2 infection (pre-Omicron or Omicron variants) and 38 healthy controls. In cases of, the study said.

The study found that placentas in both the pre-Omicron and Omicron groups revealed abnormalities.

“Infection with pre-Omicron variants, such as delta, causes significantly more damage in the form of vascular events such as clotting or bleeding compared with Omicron subtypes currently circulating in the population. ” Renowned author Patrick Kenast outlines a key. Search for the study.

The researchers attribute the varying extent of placental damage caused by different virus strains to the fact that the Omicron sub-lineages are less likely to result in severe cases than their predecessors, and as the pandemic progresses. The disease is on the rise, the vaccination rate is high. .

“In any case, our results show that two unvaccinated study participants developed placental abnormalities after infection with SARS-CoV-2 Omicron, compared to only one of the vaccinated women. Had received three doses.” Senior author Gregor Kasparin.

Oxygen, nutrients and metabolic products are exchanged between mother and baby in the placenta. Attached to the uterine wall, this organ forms such a strong barrier against the coronavirus that only 3 percent or less of fetuses whose mothers test positive for SARS-CoV-2 are infected, the study said. are

But as the study shows, the placenta itself is not immune to complications caused by Covid-19. Afterward, some unborn babies experience stunted growth or bleeding in the brain, the study says.

“This is why the placenta of pregnant women infected with SARS-CoV-2 should be examined as soon as possible after testing positive using prenatal imaging techniques,” from the Medical University of Vienna. Daniela Prior advises, citing the importance of scanning, especially for potential future coronavirus variants with delta-like mechanisms, for example.

By doing so, the study says, there is an opportunity to take steps to protect the health of the fetus in a worst-case scenario.
