SARS-CoV-2 Infection and Pregnancy: Maternal and Neonatal Outcomes and Placental Pathology Correlations.

There is accumulating evidence on the perinatal aspects of COVID-19, but available data are still insufficient. The reports on perinatal aspects of COVID-19 have been published on a small group of patients. Vertical transmission has been noted. The SARS-CoV-2 genome can be detected in umbilical cord blood and at-term placenta, and the infants demonstrate elevated SARS-CoV-2-specific IgG and IgM antibody levels. In this work, the analysis of clinical characteristics of RT-PCR SARS-CoV-2-positive pregnant women and their infants, along with the placental pathology correlation results, including villous trophoblast immunoexpression status for SARS-CoV-2 antibody, is presented. RT-PCR SARS-CoV-2 amniotic fluid testing was performed. Neonatal surveillance of infection status comprised RT-PCR testing of a nasopharyngeal swab and the measuring of levels of anti-SARS-CoV-2 in blood serum. In the initial study group were 161 pregnant women with positive test results. From that group, women who delivered during the hospital stay were selected for further analysis. Clinical data, laboratory results, placental histomorphology results, and neonatal outcomes were compared in women with immunohistochemistry (IHC)-con SARS-CoV-2-positive and IHC SARS-CoV-2-negative placentas (26 cases). A positive placental immunoprofile was noted in 8% of cases (n = 2), whereas 92% of cases were negative (n = 24). Women with placental infection proven by IHC had significantly different pathological findings from those without. One infected neonate was noted (n = 1; 4%). Infection was confirmed in perinatal autopsy, as there was the intrauterine fetal demise. The potential course of the infection with the risk of vertical transmission and implications for fetal-neonatal condition is critical for proper clinical management, which will involve comprehensive, multidisciplinary perinatal care for SARS-CoV-2-positive patients.

Placental pathology in a pregnant woman with severe COVID-19 and successful ECMO treatment: a case report.

BACKGROUND: Infection with SARS-CoV-2 during pregnancy can lead to a severe condition in the patient, which is challenging for obstetricians and anaesthesiologists. Upon severe COVID-19 and a lack of improvement after multidrug therapy and mechanical ventilation, extracorporeal membrane oxygenation (ECMO) is introduced as the last option. Such treatment is critical in women with very preterm pregnancy when each additional day of the intrauterine stay is vital for the survival of the newborn. CASE PRESENTATION: We report a case of a 38-year-old woman at 27 weeks of gestation treated with multidrug therapy and ECMO. The woman was admitted to the intensive care unit (ICU) with increasing fever, cough and dyspnoea. The course of the pregnancy was uncomplicated. She was otherwise healthy. At admission, she presented with severe dyspnoea, with oxygen saturation (SpO2) of 95% on passive oxygenation, heart rate of 145/min, and blood pressure of 145/90. After confirmation of SARS-CoV-2 infection, she received steroids, remdesivir and convalescent plasma therapy. The foetus was in good condition. No signs of an intrauterine infection were visible. Due to tachypnea of 40/min and SpO2 of 90%, the woman was intubated and mechanically ventilated. Due to circulatory failure, the prothrombotic activity of the coagulation system, further saturation worsening, and poor control of sedation, she was qualified for veno-venous ECMO. An elective caesarean section was performed at 29 weeks on ECMO treatment in the ICU. A preterm female newborn was delivered with an Apgar score of 7 and a birth weight of 1440 g. The newborn had no laboratory or clinical evidence of COVID-19. The placenta showed the following pathological changes: large subchorionic haematoma, maternal vascular malperfusion, marginal cord insertion, and chorangioma. CONCLUSIONS: This case presents the successful use of ECMO in a pregnant woman with acute respiratory distress syndrome in the course of severe COVID-19. Further research is required to explain the aetiology of placental disorders (e.g., maternal vascular malperfusion lesions or thrombotic influence of COVID-19). ECMO treatment in pregnant women remains challenging; thus, it should be used with caution. Long-term assessment may help to evaluate the safety of the ECMO procedure in pregnant women.

COVID-19 in pregnancy, management and outcomes among pregnant women and neonates - results from tertiary care center in Wroclaw.

OBJECTIVES: A novel coronavirus - SARS CoV-2 - outbreak has, for sure, been the greatest medical challenge in recent years. The maternal and neonatal consequences of the infection are still largely unknown. MATERIAL AND METHODS: This prospective study aims to describe the perinatal care and outcomes of SARS-CoV-2 positive pregnant women and their newborn infants during the third wave of the pandemic, in a large tertiary university center in Wroclaw/Poland from 15 February to 1 May 2021. RESULTS: The paper describes a group of 83 women with confirmed SARS-CoV-2 infection during delivery, as well as their newborn infants (n = 84). The course of COVID-19 disease in pregnant patients was mostly asymptomatic (56%) but 31% women manifested mild to moderate symptoms and 14% had severe infection. The median gestational age at the delivery was 38 weeks. On average, 16.7% of mothers were separated from their newborns at birth, 83.3% practiced skin-to-skin, and roomed in with their babies, and 84.5% of the infants received any mother'smilk. Preterm infants were more often borne by mothers with symptomatic course of COVID-19 infection. Need for neonatal treatment was only due to prematurity. Neonates with acquired infection (after 14th day of life) had to be treated symptomatically with fever and loose stools, only 28.5% had symptoms of respiratory failure. CONCLUSIONS: Despite the confirmed SARS-CoV-2 infection, the majority of mother- infant dyads were in a good health condition. The data on perinatal care reported in the paper could be helpful contribution supporting childbirth physiology protection during the COVID-19 pandemic.
