Introduction: SARS-CoV-2 infection in the perinatal period may be associated with an increased risk of morbidity and mortality in both the mother and the neonate.
Objective: To describe the clinical characteristics and laboratory and imaging findings in pregnant women with COVID-19 and their newborns.
Materials and methods: A search was conducted in PubMed, Scopus, Web of Science, and Cochrane databases for systematic reviews published between February 1, 2020, and May 30, 2021, describing clinical characteristics and laboratory and imaging (chest) findings in pregnant women with COVID-19 and their newborns; there were no language restrictions. Data were reanalyzed by means of Bayesian meta-analysis using Markov Chain Monte Carlo (MCMC) methods. The study protocol is registered in PROSPERO under code CRD42020178329.
Results: Six systematic reviews were retrieved (for a total of 617 primary studies). A narrative synthesis of the percentage of signs, symptoms, and imaging and laboratory findings found in both mothers and neonates was performed. Odds ratios (OR) between pregnant women with and without COVID-19 were: fetal well-being involvement: 1.9 (95%CI: 1.09-3.63); stillbirth: 1.73 (95%CI: 1.01-2.94); preterm birth: 1.77 (95%CI: 1.25-2.61); and maternal admission to the intensive care unit (ICU): 6.75 (95%CI: 1-31.19). Regarding symptomatology, an OR of 0.67 (95%CI: 0.51-0.93) was obtained for myalgia between pregnant women and non-pregnant women with COVID-19.
Conclusions: Cough, fever, dyspnea, and myalgia are the most common symptoms in pregnant women with COVID-19; in addition, there is a higher risk of admission to the ICU among them. Regarding complementary testing, the most frequent alterations are lymphopenia and the evidence of lesions in chest imaging studies. The presence of COVID-19 in pregnant women is associated with preterm birth. It seems that SARS-CoV-2 infection in neonates is not severe and that the risk of vertical transmission is low, considering that no data on congenital malformations attributable to the virus were found.
Introducción. La infección por SARS-CoV-2 en el periodo perinatal puede asociarse a un mayor riesgo de morbimortalidad tanto en la madre como en el neonato.
Objetivo. Describir las características clínicas y los hallazgos de laboratorio e imagenológicos en gestantes con COVID-19 y sus recién nacidos.
Materiales y métodos. Se realizó una búsqueda en PubMed, Scopus, Web of Science y Cochrane de revisiones sistemáticas, publicadas entre el 1 de febrero de 2020 y el 30 de mayo de 2021, que describieran características clínicas y hallazgos de exámenes de laboratorio y de imagen (tórax) en gestantes con COVID-19 y sus recién nacidos; no hubo restricciones de idioma. Se reanalizaron los datos mediante metaanálisis bayesianos utilizando métodos de Monte Carlo basados en Cadenas de Markov. El protocolo del estudio está registrado en PROSPERO bajo el código CRD42020178329.
Resultados. Se recuperaron 6 revisiones sistemáticas (para un total de 617 estudios primarios). Se realizó una síntesis narrativa de las proporciones de los signos, síntomas y hallazgos imagenológicos y de laboratorio tanto de las madres, como de los neonatos. Las Odds ratio (OR) entre las embarazadas con y sin COVID-19 fueron: compromiso del bienestar fetal: 1.9 (IC95%:1.09-3.63), mortinato: 1.73 (IC95%:1.01-2.94), nacimiento prematuro: 1.77 (IC95%:1.25-2.61) y admisión de la madre a unidad de cuidados intensivos (UCI): 6.75 (IC95%: 1-31.19). Con relación a la sintomatología: la OR para la mialgia entre las embarazadas y las no embarazadas con COVID-19 fue 0.67 (IC95%:0.51-0.93).
Conclusiones. Los síntomas más comunes en las embarazadas con COVID-19 son tos, fiebre, disnea y mialgias; además, existe un mayor riesgo de ingreso a UCI. En lo que respecta a los exámenes complementarios, las alteraciones más frecuentes son la linfopenia y las lesiones evidenciadas en los estudios de imagen del tórax. La presencia de COVID-19 en las gestantes se asocia con nacimiento prematuro. Al parecer, la infección por SARS-CoV-2 en neonatos no es grave y el riesgo de transmisión vertical es bajo, pues no se encontraron datos sobre malformaciones congénitas atribuibles al virus.
