A study developed by scientists from the Pontifical Catholic University of Paran\u00e1 (PUCPR), in partnership with researchers from the Pel\u00e9 Pequeno Pr\u00edncipe Research Institute, concluded that COVID-19 can compromise the placenta of pregnant women, causing premature births and even intrauterine death. The study was published in the journal Frontiers in Immunology<\/em>, a scientific journal of worldwide reference in immunology.<\/p>\n\n\n\n

The scientists compared the placenta of 19 mothers diagnosed with COVID-19 (from the Nossa Senhora das Gra\u00e7as Hospital \u2013 HNSG, abbreviation in Portuguese) to that of 19 healthy mothers (from the Federal University of Paran\u00e1 \u2013 UFPR, in Portuguese). The study followed the pairing (maternal age, gestational age and comorbidities between the two groups). The pregnant women in the COVID-19 group were seen at the Nossa Senhora das Gra\u00e7as Hospital, and those in the control group, at the Hospital de Cl\u00ednicas (HC), both in Curitiba, with the patients\u2019 consent and approval from the institutions\u2019 Ethics Committees.<\/p>\n\n\n\n

\u201cWhen comparing the placentas of mothers with COVID-19 to those of healthy mothers, we realized that those contaminated by SARS-CoV-2 were more likely to show characteristics of vascular malperfusion due to placental, maternal and fetal thrombosis,\u201d explains scientist and professor Cleber Machado de Souza, who is part of the group of researchers in this study.<\/p>\n\n\n\n

\u201cThe placenta is the baby\u2019s lung. It is where the baby breathes and receives nutrients, through the mother\u2019s vessels. If COVID-19 affects the mother\u2019s vessels, the baby doesn\u00b4t receive nutrients and oxygen,\u201d says professor and PUCPR researcher L\u00facia de Noronha. In this sense, consequences for the babies were verified, such as intrauterine death, death right after birth, and premature births. Some newborns also needed to be hospitalized for having been infected with the virus.<\/p>\n\n\n\n

Patients with the mild form of the disease, however, gave birth to healthy babies and their placentas showed no lesions from SARS-CoV-2 infection.<\/p>\n\n\n\n

Prevention is paramount<\/strong>
Professor Souza argues that prevention is still the best way for pregnant women not to get infected with COVID-19, since, so far, there are no specific therapies proven effective for treating the disease.<\/p>\n\n\n\n

\u201cIn some situations, obstetricians prefer to induce premature labor to remove the baby and prevent him from dying in utero. Even so, some children have been infected with the coronavirus from their mothers, as the disease can be transmitted through the placenta. Newborn babies with COVID-19 can develop the severe form of the disease, dying,\u201d says L\u00facia.<\/p>\n\n\n\n

Next steps<\/strong>
According to Souza, the research will continue, now evaluating the genetic aspects involved. \u201cWe want to understand why some women have a greater propensity to develop thrombosis while others do not. We will extract DNA from these 38 placentas [19 from mothers with COVID-19 and 19 from healthy mothers] and perform the process of genotyping genes associated with the event of thrombosis. This approach seeks to find genetic markers associated with higher risk and thus would allow early identification of patients more susceptible to the worst thrombotic outcome in pregnancy. And this could, in the future, help to establish safer conducts in the conduction of pregnancies associated to COVID-19,\u201d he highlight.<\/p>\n","protected":false},"excerpt":{"rendered":"
