- The Influenza Vaccine May Protect Pregnant and Postpartum Women against Severe COVID-19(2022) PAGANOTI, Cristiane de Freitas; RODRIGUES, Agatha Sacramento; FRANCISCO, Rossana Pulcineli Vieira; COSTA, Rafaela Alkmin daThe SARS-CoV-2 pandemic has imposed a huge challenge on the antenatal care of pregnant women worldwide, with the maternal mortality rate being raised to alarming levels. While COVID-19 vaccines were developed, some studies highlighted a possible relationship between influenza vaccination and lower odds of COVID-19 infection. As obstetric patients belong to a high-risk group for respiratory diseases, this study evaluated whether influenza vaccination reduces the severity of COVID-19 infection and mortality among pregnant and postpartum women. We conducted a retrospective cohort study on 3370 pregnant and postpartum women from the Brazilian national database, where they were grouped according to their influenza vaccination status before the onset of COVID-19 symptoms. The intensive care unit admission and intubation rates were significantly higher among subjects in the unvaccinated group (p = 0.002 and p < 0.001, respectively). The odds of mortality risk among those who received the vaccine was 0.33, with a 95% confidence interval of 0.23-0.47. The numbers of patients who needed to be vaccinated to avoid a case of intensive care unit admission, intubation, or death due to COVID-19 were 11, 15, and 11, respectively. Influenza vaccines could confer protection against severe COVID-19 infection in pregnant and postpartum women.
- COVID-19: Impact of Original, Gamma, Delta, and Omicron Variants of SARS-CoV-2 in Vaccinated and Unvaccinated Pregnant and Postpartum Women(2022) SERRA, Fabiano Elisei; ROSA JUNIOR, Elias Ribeiro; ROSSI, Patricia de; FRANCISCO, Rossana Pulcineli Vieira; RODRIGUES, Agatha SacramentoThis study compares the clinical characteristics and disease progression among vaccinated and unvaccinated pregnant and postpartum women who tested positive for different variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) using the Brazilian epidemiological data. Data of pregnant or postpartum patients testing positive for SARS-CoV-2 and presenting with coronavirus disease 2019 (COVID-19) from February 2020 to July 2022 were extracted from Brazilian national database. The patients were grouped based on vaccination status and viral variant (original, Gamma, Delta, and Omicron variants), and their demographics, clinical characteristics, comorbidities, symptoms, and outcomes were compared retrospectively. Data of 10,003 pregnant and 2361 postpartum women were extracted from the database. For unvaccinated postpartum women, intensive care unit (ICU) admission was more likely; invasive ventilation need was more probable if they tested positive for the original, Gamma, and Omicron variants; and chances of death were higher when infected with the original and Gamma variants than when infected with other variants. Vaccinated patients had reduced adverse outcome probability, including ICU admission, invasive ventilation requirement, and death. Postpartum women showed worse outcomes, particularly when unvaccinated, than pregnant women. Hence, vaccination of pregnant and postpartum women should be given top priority.
- The Effect of Being Pregnant during Respiratory Pandemics: A Comparison between 2009/10 Flu and 2020/21 COVID-19 Pandemic in Brazil(2022) ZANON, Ana Beatrice Bonganha; ROSA JUNIOR, Elias Ribeiro; MONROY, Nataly Adriana Jimenez; GODOI, Luciana Graziela de; MATTOS, Bruna Rodrigues de; PAGANOTI, Cristiane de Freitas; FRANCISCO, Rossana Pulcineli Vieira; RODRIGUES, Agatha Sacramento; COSTA, Rafaela Alkmin daPregnant women undergo physiological changes that make them a challenging group of patients during pandemic respiratory diseases, as previously found during H1N1 2009 pandemic and recently ratified in COVID-19 pandemic. We conducted a retrospective cohort analysis on 5888 hospitalized women for H1N1 flu pandemic (2190 pregnant and 3698 non-pregnant) and 64,515 hospitalized women for COVID-19 pandemic (5151 pregnant and 59,364 non-pregnant), from the Brazilian national database, to compare demographic profile, clinical aspects, and mortality in childbearing aged women during both pandemics. Additionally, the effect of being pregnant was compared between both pandemics. In both pandemics, pregnant women were younger than non-pregnant women. Overall, pregnant women had lower frequencies of comorbidities and were less symptomatic. Among hospitalized women, pregnant women presented lower mortality rates than non-pregnant women (9.7% vs. 12.6%, p = 0.002 in the H1N1 pandemic and 9.7% vs. 17.4%, p < 0.001 in the COVID-19 pandemic) and this difference was statistically more pronounced in the COVID-19 pandemic, even after balancing pregnant and non-pregnant groups regarding age and chronic diseases.
- Prone Positioning: A Safe and Effective Procedure in Pregnant Women Presenting with Severe Acute Respiratory Distress Syndrome(2022) JR, Gilmar de Souza Osmundo; PAGANOTTI, Cristiane de Freitas; COSTA, Rafaela Alkmin da; SILVA, Thiago Henrique dos Santos; BOMBONATI, Paula Carolina; MALBOUISSON, Luiz Marcelo Sa; FRANCISCO, Rossana Pulcineli VieiraProne positioning (PP) improves oxygenation and survival in patients with severe acute respiratory distress syndrome (ARDS). Data regarding feasibility and effectiveness of PP in pregnancy are lacking. This subgroup analysis of a cohort study that included mechanically ventilated pregnant women presenting with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-induced ARDS who underwent PP aims to assess the efficacy and safety of PP. Ventilatory and gasometric parameters were evaluated at baseline (T-0) and in prone (T-1) and supine (T-2) positions. Obstetric outcomes were also assessed. Sixteen cases at an average of 27.0 (22.0-31.1) gestational weeks of pregnancy were included. Obesity and hypertension were frequent comorbidities. PP was associated with a >20% increase in PaO2 levels and in PaO2/FiO(2) ratios in 50% and 100% of cases, respectively. The PaO2/FiO(2) ratio increased 76.7% (20.5-292.4%) at T-1 and 76.9% (0-182.7%) at T-2. PP produced sustained improvements in mean PaO2/FiO(2) ratio (p < 0.001) and PaCO2 level (p = 0.028). There were no cases of emergency delivery or suspected fetal distress in pregnancies >= 25 weeks during the 24 h period following PP. PP is safe and feasible during pregnancy, improving PaO2/FiO(2) ratios and helping to delay preterm delivery in severe ARDS.
