Evaluation of the effects of COVID-19 disease and the trimester in which the disease is diagnosed on obstetric and neonatal outcomes: A retrospective cohort study

Emre Sertel et al.

Summary: This study evaluated the effects of COVID-19 disease and the trimester of diagnosis on obstetric and neonatal outcomes. Results showed that COVID-19 disease during pregnancy was associated with adverse outcomes such as maternal hypertensive disease, preterm birth, low birth weight, and low Apgar scores. The highest frequency of preterm birth was observed in pregnant women diagnosed with COVID-19 in the second trimester, and cesarean section rates increased as the trimester of diagnosis progressed.

The results showed that SARS-CoV-2 infection before 28 weeks of gestation was associated with an increased risk of fetal or neonatal death, preterm birth, and hypertensive disorders of pregnancy. However, there was no significant association between SARS-CoV-2 infection during pregnancy and low birth weight or major congenital malformations.

The results showed that pregnant women infected with the Delta variant had a 9.4% ICU admission rate and a 5.2% mortality rate. Pregnant women in the severe group had significantly higher rates of preterm birth and cesarean section. Close monitoring of CRP, WBC, and procalcitonin levels is recommended.

Summary: This study describes the clinical characteristics, pregnancy, and infant outcomes in pregnant individuals with laboratory-confirmed SARS-CoV-2 infection by trimester of infection. The results show that infection in the third trimester is associated with a higher risk of preterm birth, but there is no difference in the prevalence of birth defects by trimester of infection. The importance of this study lies in reminding individuals to take COVID-19 prevention strategies, including vaccination, during pregnancy.

Maternal mortality and COVID-19

Maira L. S. Takemoto et al.

Summary: This study identified 20 COVID-19-related maternal deaths in Brazil, with most occurring in the postpartum period and a range of 20-43 years old. Asthma was the most common risk factor, and cases were concentrated in the Northeast and Southeast regions, particularly in Sao Paulo. The study suggests that barriers to healthcare, differences in pandemic containment measures, and high prevalence of risk factors for severe COVID-19 may contribute to the observed disparity in maternal outcomes compared to worldwide reports.

Major predictors of severe COVID-19 in pregnant women include decreased levels of erythrocytes and lymphocytes, and increased levels of alanine aminotransferase and CRP. There is no evidence of vertical transmission, but this possibility cannot be excluded.

Transplacental viral transmission is very rare, with no typical placental changes, and maternal-fetal hypoxia in the context of pneumonia seems to be the most important prognostic factor.

Summary: Infections during pregnancy pose a significant threat to maternal and fetal health, with the placenta having robust mechanisms to defend against microbial transmission. However, pathogens causing congenital disease may have evolved diverse mechanisms to bypass these defences. This review discusses how TORCH pathogens breach the maternal-fetal interface and cause disease.

The Inflammatory Cytokine Imbalance for Miscarriage, Pregnancy Loss and COVID-19 Pneumonia

Fortunato Vesce et al.

Summary: Pregnancy is a vascular event controlled by endocrine factors. During pregnancy, the chorionic villi penetrate the uterine spiral arteries to provide nutrients and oxygen for fetal growth. Vascular function is regulated by prostaglandins and thromboxane for vasoconstriction, and prostacyclin for vasodilation. The fetus can alter the maternal immune response to protect itself. Inflammation is a leading cause of pregnancy-related complications. In both COVID-19 pneumonia and gestational inflammation, preventing and counteracting inflammation is crucial.

The researchers observe robust infection of trophectoderm cells and detect cases of infection that compromise embryo health when exposing human blastocysts to live SARS-CoV-2. This identifies a new human target tissue for SARS-CoV-2 with potential medical implications for reproductive health during the COVID-19 pandemic and its aftermath.

Evaluation of maternal serum afamin and vitamin E levels in pregnant women with COVID-19 and its association with composite adverse perinatal outcomes

Seyit A. Erol et al.

Summary: This study evaluated the levels of maternal serum afamin and vitamin E in pregnant women with COVID-19 and their association with composite adverse perinatal outcomes. The COVID-19 group had a higher obstetric complication rate, higher afamin levels, and lower vitamin E levels. The results suggest that higher afamin and lower vitamin E levels may be related to increased oxidative stress in COVID-19 pathogenesis and adverse perinatal outcomes.

Infected mothers had higher risks of post-partum hemorrhage, transfusions, and ICU admissions compared to uninfected ones, as well as a higher risk of intra-uterine fetal demise. No differences were observed in other maternal, obstetrical, or neonatal outcomes between the two groups.
