- Placental pathological findings in coronavirus disease 2019: Perinatal outcomes(2022) ARCOS JUNIOR, Gelson Farias; FRANCISCO, Rossana Pulcineli Vieira; KILL, Beatriz; PERES, Stela Verzinhasse; GIBELLI, Maria Augusta B. C.; IBIDI, Silvia Maria; CARVALHO, Werther Brunow de; SIMOES, Angelica Braz; BRIZOT, Maria de Lourdes; SCHULTZ, Regina; CARVALHO, Mariana AzevedoIntroduction: Placental alterations caused by severe acute respiratory coronavirus-2 (SARS-CoV-2) infection have already been described, but most studies used small sample groups and the difference according to the severity of the disease has not been verified. Our objective was to describe placental alterations in patients with coronavirus disease 2019 (COVID-19) and analyze the association of pathological placental findings with the clinical pa-rameters of COVID-19 and perinatal results.Methods: This was a nested study within a prospective cohort study involving 109 symptomatic pregnant women with COVID-19. The prevalence of observed placental alterations was described, and the associations of path-ological findings with the clinical parameters of COVID-19 severity and with perinatal outcomes were assessed.Results: The frequency of types of placental features was poor maternal vascular perfusion in 45% of cases, poor fetal vascular perfusion in 33.9%, hematogenous origin infection in 32.1%, and morphological changes corre-sponding to ascending infection in 21.1%. Hematogenous infection differed significantly according to COVID-19 severity (p = 0.008), with a prevalence ratio (PR) of 1.74 (95% confidence interval, 1.02-2.98) in the moderate COVID-19 group compared to the mild COVID-19 group. Among the perinatal outcomes, there was an unex-pected inverse association between prematurity and placental infection of hematogenous origin, with lower rates of prematurity among cases with inflammation of hematogenous origin (p = 0.029).Discussion: Moderate SARS-Cov-2 infection presented a higher prevalence of placental pathological findings. There was no association of placental findings with adverse perinatal outcomes.
- Impact of SARS-CoV-2 on pregnancy and neonatal outcomes: An open prospective study of pregnant women in Brazil(2022) GOMEZ, Ursula Trovato; FRANCISCO, Rossana Pulcineli Vieira; BAPTISTA, Fernanda Spadotto; GIBELLI, Maria Augusta B. C.; IBIDI, Silvia Maria; CARVALHO, Werther Brunow de; PAGANOTI, Cristiane de Freitas; SABINO, Ester Cerdeira; SILVA, Lea Campos de Oliveira da; JAENISCH, Thomas; MAYAUD, Philippe; BRIZOT, Maria de LourdesObjectives: To determine the incidence and risk of adverse obstetric and neonatal outcomes according to SARSCoV-2 infection severity in pregnant women. Method: Open prospective study of pregnant women tested for SARS-CoV-2 by serological and molecular assays during pregnancy or delivery in two hospitals in Sao Paulo, Brazil from April 12, 2020, to February 28, 2021. Five groups were considered for analysis: C0, negative COVID-19 results and no COVID-19 symptoms; C1, positive COVID-19 results, and no symptoms; C2, positive COVID-19 results with mild symptoms; C3, positive COVID-19 results with moderate symptoms; and C4, positive COVID-19 results with severe symptoms. The association between obstetric and neonatal outcomes and COVID-19 severity was determined using multivariate analysis. Results: 734 eligible pregnant women were enrolled as follows: C0 (n = 357), C1 (n = 127), C2 (n = 174), C3 (n = 37), and C4 (n = 39). The following pregnancy and neonatal outcomes were associated with severe COVID19: oligohydramnios (adjusted Odds Ratio [aOR] = 6.18; 95% CI 1.87-20.39), fetal distress (aOR = 4.01; 95% Confidence Interval [CI] 1.84-8.75), preterm birth (aOR = 5.51; 95% CI 1.47-20.61), longer hospital stay (aOR = 1.66; 95% CI 1.36-2.02), and admission to the neonatal intensive care unit (aOR = 19.36; 95% CI, 5.8663.99). All maternal (n = 6, 15.4%, p < 0.001) and neonatal (n = 5, 12.5%, p < 0.001) deaths and most fetal deaths (n = 4, 9.8%, p < 0.001) occurred in C4 group. Moderate COVID-19 was associated with oligohydramnios (aOR = 6.23; 95% CI 1.93-20.13) , preterm birth (aOR = 3.60; 95% CI 1.45-9.27). Mild COVID-19 was asso-ciated with oligohydramnios (aOR = 3.77; 95% CI 1.56-9.07). Conclusion: Adverse pregnancy and neonatal outcomes were associated with maternal symptomatic COVID-19 sta-tus , risk increased with disease severity.
- Clinical characteristics and evolution of 71 neonates born to mothers with COVID-19 at a tertiary center in Brazil(2022) DUARTE, Bruna de Paula; KREBS, Vera Lucia Jornada; CALIL, Valdenise Martins Laurindo Tuma; CARVALHO, Werther Brunow de; GIBELLI, Maria Augusta Bento Cicaroni; FRANCISCO, Rossana Pulcineli VieiraIntroduction: Limited data are available on pregnant women with COVID-19 and their neonates.Objective: This study aimed to describe clinical characteristics and evolution from birth to discharge of a retrospec-tive cohort of 71 neonates, with one set of twins, born to women with COVID-19 diagnosed at the end of preg-nancy. The authors included all newborns admitted into a neonatal unit of a tertiary hospital in Brazil, between March 2020 and March 2021, whose unvaccinated mothers had COVID-19 symptoms and RT-PCR (Real-Time Polymerase Chain Reaction) for SARS-CoV-2 positive within fourteen days prior to delivery. Newborns to mothers with COVID-19 symptoms and negative tests for SARS-CoV-2 were excluded. Results: The main route of birth delivery was cesarean, corresponding to 60 pregnant women (84.5%). The fore-most indications for cesarean were pregnant with critical disease (24.6%) and acute fetal distress (20.3%). The mean birth weight was 2452 g (865-3870 g) and the mean gestational age was 345/7 weeks (25-40 weeks). There were 45 premature newborns (63.3%), of which 21 newborns (29.5%) were less than 32 weeks of gestational age. RT-PCR for SARS-CoV-2 on oropharyngeal swabs was positive in 2 newborns (2.8%) and negative in the other 69 newborns (97.2%). Most newborns (51.4%) needed respiratory support. Therapeutic interventions dur-ing hospitalization were inotropic drugs (9.9%), antibiotics (22.8%), parenteral nutrition (26.8%), and photother-apy (46.5%).Conclusion: Maternal COVID-19 diagnosticated close to delivery has an impact on the first days of neonatal life.
