RESUMO
Introducción: La repercusión de la infección asintomática por SARS-CoV-2 sobre el crecimiento fetal no ha sido bien establecida. El objetivo de este estudio fue determinar si existe un incremento del riesgo de retraso de crecimiento intrauterino en gestaciones con una infección asintomática por SARS-CoV-2 durante el embarazo. Material y métodos: Estudio retrospectivo caso-control en gestantes con feto pequeño para la edad gestacional o restricción del crecimiento intrauterino. Los grupos se constituyeron según el percentil de peso al nacimiento. El antecedente de infección por SARS-CoV-2 ha sido definido por la presencia de IgG en el momento del ingreso hospitalario para el parto. Resultados: No se encontraron diferencias significativas entre el grupo control y el grupo caso en cuanto a anticuerpos IgG positivos (11,5 vs. 8,8%). Tampoco se registraron diferencias en la prematuridad ni el tipo de parto. Conclusiones: La infección asintomática por SARS-CoV-2 durante el embarazo no parece afectar al crecimiento fetal.(AU)
Introduction: The impact of asymptomatic infection by SARs-CoV-2 on foetal growth has not been described. The purpose of our study is to determine whether there is an increased risk of foetal growth restriction in pregnancies in which asymptomatic or mild infection by SARS-CoV-2 has been detected. Material and methods: Retrospective case-control study with a subset of pregnant women with a small for gestational age foetus. Groups were established according to birth weight percentile. Previous SARS-CoV-2 infection was defined by positive antibodies obtained on admission to hospital for delivery. Results: No statistically significant differences between controls and cases were recorded in terms of positive IgG antibodies (11.5 vs. 8.8%). There were no premature births or significant differences in the date or type of delivery. Conclusions: Asymptomatic infection by SARs-CoV-2 during pregnancy does not seem to affect foetal growth.(AU)
