Perinatal transmission with SARS-CoV-2 and route of pregnancy termination: a narrative review.

OBJECTIVE: Analyze newborns diagnosed with SARS-CoV-2 performed with RT-PCR at birth or during the first days of birth and to look for an association with the route of birth. METHODS: We conducted a comprehensive literature search for newborns diagnosed with COVID-19 using PubMed, LILACS and Google scholar until May 15, 2020, looking for published articles with pregnancy, vertical transmission, intrauterine transmission, neonates, delivery. RESULTS: There were found 10 articles with a total of 15 newborn infected with SARS-CoV-2 according to positive PCR at birth or in the first days of birth. Eleven newborn birth by cesarean section and 4 vaginally. Of the 11 cases with cesarean section, two presented premature rupture of the membranes. Seven newborns developed pneumonia, of which two had ruptured membranes and one was born by vaginal delivery. CONCLUSION: This review shows that there is perinatal or neonatal infection with SARS-CoV-2 by finding a positive PCR in the first days of birth. In addition, that there is more possibility of neonatal infection if the birth is vaginal or if there is premature rupture of the membranes before cesarean section. Vaginal delivery and premature rupture of membranes should be considered as risk factors for perinatal infection.

COVID 19 and high pregnancy and perinatal complications in Panama.

OBJECTIVES: To report the maternal and neonatal results of patients infected with COVID-19 in Panama. METHODS: The study is based on the analysis of pregnant women with COVID-19, in five hospitals in the Republic of Panama. The inclusion criteria were: patients with or without symptoms, positive RT-PCR for SARS-CoV-2 in the period from March 23 to 6 months after, whose births were attended in one of those five hospitals and who signed the consent. Data were obtained at the time of diagnosis of the infection and at the time of termination of pregnancy for the mother and newborn. RESULTS: Two hundred and fifty-three patients met the inclusion criteria. Most were diagnosed in the third trimester (89.3%). 10.3% of the patients presented in a severe form of COVID-19. The most frequent complication was pre-eclampsia and if we add gestational hypertension they represent 21.2%; most of the patients terminated the pregnancy by cesarean section (58%). 26.9% (95% CI 21.3-32.9%) of the births were premature, and perinatal mortality was 5.4% (95% CI 3.0-9.0%). There was a need for mechanical ventilation in 5.9% (95% CI 3.6-9.6%) of the cohort and there were four maternal deaths (1.6% - 95% CI 0.6-4.0%). CONCLUSIONS: This study of pregnant women infected with COVID-19 and diagnosed with RT-PCR shows serious maternal complications such as high admission to the ICU, need for mechanical ventilation and one death in every 64 infected. Frequent obstetric complications such as hypertension, premature rupture of membranes, high rate of prematurity, and perinatal lethality were also seen.

RESUMEN Objetivo . Buscar toda la información y evidencia disponible sobre el SARS-CoV-2 -que surgió en estos primeros 4 meses de 2020y el embarazo. Metodología . Revisión sistemática en las bases de datos PubMed y Google Scholar, hasta el 25 de abril de 2020. Se buscó artículos publicados relacionados con mujeres embarazadas infectadas con SARS-CoV-2. No hubo restricción de idioma. La búsqueda se extendió a las referencias de los artículos encontrados. Resultados . La enfermedad COVID-19 en mujeres embarazadas se caracteriza porque más del 90% de las pacientes evoluciona en forma leve, 2% requiere ingresar a las unidades de cuidados intensivos. Una muerte materna ha sido reportada. La prematuridad es alrededor de 25%, con predominio de recién nacidos prematuros tardíos; aproximadamente el 9% se complica con rotura prematura de membranas; la mortalidad perinatal es baja o similar a la de la población general y no se ha demostrado la transmisión vertical. Conclusiones . Los ginecólogos obstetras deben prepararse para atender cada vez más casos con COVID-19 y, por lo tanto, es necesario tener su conocimiento. La enfermedad evoluciona de la misma manera que en las no embarazadas, genera mayor prematuridad, no se ha demostrado la transmisión vertical, pero hay altas posibilidades de transmisión horizontal durante el parto vaginal.

ABSTRACT Objective : To search for all the information and available evidence on infection with SARS-CoV-2, a virus that appeared during the first 4 months of 2020, and pregnancy. Methods : Systematic review in PubMed and Google Scholar databases until April 25, 2020. We searched for published articles related to pregnant women infected with SARS-CoV-2. There was no language restriction. The search was extended to the references of the articles found. Results : In pregnant women with COVID-19, more than 90% of patients evolve mildly, 2% require intensive care. One maternal death has been reported. Prematurity occurs in approximately 25% of the cases, with predominance of late preterm infants; premature rupture of membranes presents in about 9%. Perinatal mortality is lower or similar to that of the general population, and vertical transmission has not been shown. Conclusions : Obstetrician-gynecologists must prepare to attend more cases with COVID-19 and therefore they need to know this disease. COVID-19 progresses similarly in pregnant and non-pregnant women, although it is associated to prematurity. While vertical transmission has not been demonstrated, horizontal transmission during vaginal birth is very likely.
