Clinical and Obstetric Aspects of Pregnant Women with COVID-19: A Systematic Review

Abstract

Objective To analyze the clinical and obstetric aspects of pregnant women with COVID-19.

Methods A systematic literature review in the MEDLINE/PubMed, LILACS, SCIELO, and CNKI databases was performed from March to May 2020, with the descriptors: Pregnancy; 2019-nCov; Coronavirus; SARS-Cov-2, Covid-19. Of those chosen were original titles, without language and period restriction and that addressed pregnant women with a clinical and/or laboratory diagnosis of COVID-19. Revisions, editorials, and duplicate titles were excluded. The Newcastle-Ottawa (NOS) and Murad et al. scales were used to assess the quality of the studies.

Results We included 34 articles with 412 pregnant women infected with severe acute respiratory syndrome (SARS-Cov-2), with an average age of 27.5 years of age and 36.0 gestational weeks. The most common symptom was fever (205 [49.7%]), and 89 (21.6%) pregnant women progressed to severe viral pneumonia. Laboratory tests showed an increase in C-reactive protein (154 [37.8%]), and radiological tests showed pneumonia with peripheral ground-glass pattern (172 [51.4%]). Emergency cesarean delivery was indicated for most pregnant women, and the most common gestational complication was premature rupture of ovarian membranes (14 [3.4%;]). We detected 2 (0.5%) neonatal deaths, 2 (0.5%) stillbirths, and 1 (0.2%) maternal death.

Conclusion Pregnant women with COVID-19 presented a clinical picture similar to that of non-infected pregnant women, with few obstetric or neonatal repercussions. There was a greater indication of cesarean deliveries before the disease aggravated, and there was no evidence of vertical transmission of the infection.

Resumo

Objetivo Analisar os aspectos clínicos e obstétricos de gestantes com COVID-19.

Métodos Revisão sistemática da literatura nas bases: MEDLINE/PubMed, LILACS, SCIELO e CNKI, realizada de março a maio de 2020, com os descritores Pregnancy; 2019-nCov; Coronavirus; SARS-Cov-2, Covid-19. Elegeram-se títulos originais, sem restrição de idioma e período e que abordassem gestantes com diagnóstico clínico e/ou laboratorial de COVID-19. Excluíram-se revisões, editoriais, títulos duplicados. As escalas de Newcastle-Ottawa (NOS, na sigla em inglês) e a de Murad et al. foram utilizadas para avaliar a qualidade dos estudos.

Resultados Foram incluídos 34 artigos com 412 gestantes infectadas pela síndrome respiratória aguda grave (SARS-Cov, na sigla em inglês) com idade média de 27,5 anos e média de 36,0 semanas gestacionais. O sintoma mais incidente foi a febre (49,7%;205). e 89 (21,6%) gestantes evoluíram para pneumonia viral grave. Os exames laboratoriais demonstraram aumento da proteína C reativa (37,8%; 154) e os radiológicos mostraram pneumonia com padrão em vidro fosco periférico (51,4%; 172). O parto cesáreo de emergência foi indicado para a maior parte das gestantes, e a complicação gestacional mais comum foi a ruptura prematura de membranas ovulares (3,4%; 14). Foram detectados 2 (0,5%) mortes neonatais, 2 (0,5%) natimortos, e 1 (0,2%) morte materna.

Conclusão Gestantes com doença coronavírus (COVID-19, na sigla em inglês apresentaram quadro clínico semelhante a gestantes não infectadas, com poucas repercussões obstétricas ou neonatais. Houve uma maior indicação de partos cesáreos antes do agravamento da doença e não se observaram evidências de transmissão vertical da infecção.
