ABSTRACT
Abstract Objective Preeclampsia is a major cause of perinatal and maternal morbidity and mortality. Our objective is to assess the performance of a combined screening test for preeclampsia in the first trimester and the prophylactic use of low-dose aspirin. Methods Prospective study of all women attending our hospital for the first-trimester screening of aneuploidies, between March 2017 and February 2018 (n = 1,297). The exclusion criteria weremultiple pregnancy andmajor fetal abnormalities. Preeclampsia screening was performed with an algorithm that includes maternal characteristics, and biophysical and biochemical biomarkers. High-risk was defined as a risk ≥ 150 of earlyonset preeclampsia (before 34 weeks), in which cases low-dose aspirin (150mg at night) was offered to these women from screening until 36 weeks. Results From the 1,272 enrolled participants, the majority were Caucasian (1,051; 82.6%) and multiparous (658, 51.7%). Fifty patients (3.9%) screened high-risk for preeclampsia, and all started a low-dose aspirin regimen, with good compliance (96%). Early-onset preeclampsia was found in 3 pregnant women (0.24%), and total preeclampsia was diagnosed in 25 (2.02%), compared with 28 (0.75%) cases of early preeclampsia (p = 0.0099) and 98 (2.62%) of total preeclampsia (p = 0.2904) before the implementation of screening. Conclusion There was a lower incidence of both, early-onset and total preeclampsia, after the introduction of universal screening and prophylactic use of low-dose aspirin. This reduction was statistically significant in early-onset preeclampsia. The association of a first-trimester combined screening model and aspirin prophylaxis appears to be useful in predicting and reducing the incidence of early-onset preeclampsia, in a routine care setting.
RESUMO
Resumo Objetivo A pré-eclâmpsia é uma causa importante de morbi-mortalidade materna e perinatal. Os objetivos do nosso estudo foram avaliar a implementação do rastreio combinado de pré-eclâmpsia no primeiro trimestre e o uso profilático de aspirina em baixa dose. Métodos Estudo prospetivo das mulheres referenciadas ao nosso hospital para realização do rastreio do primeiro trimestre de aneuploidias, entre março de 2017 e fevereiro de 2018 (n = 1.297). Os critérios de exclusão foram gravidez múltipla e anomalias fetais graves. O algoritmo usado no rastreio da pré-eclâmpsia combina características maternas, e marcadores biofísicos e bioquímicos. Definiu-se alto risco como risco de pré-eclâmpsia precoce (antes das 34 semanas) ≥ 150, tendo sido recomendada aspirina em baixa dose (150 mg à noite) desde o rastreio até às 36 semanas. Resultados Das 1.272 participantes, a maioria era caucasiana (1.051; 82,6%) e multípara (658; 51,7%). Cinquenta grávidas (3,9%) foram consideradas de alto risco para pré-eclâmpsia e todas iniciaram aspirina em baixa dose, com boa adesão (96%). Pré-eclampsia precoce foi diagnosticada em 3 grávidas (0,24%), e no total foram diagnosticados 25 casos de pré-eclâmpsia (2,02%), comparativamente com 28 (0,75%) casos de pré-eclampsia precoces (p = 0,0099) e 98 (2,62%) casos totais de préeclâmpsia (p = 0,2904) observados antes da implementação do rastreio. Verificou-se uma menor incidência de pré-eclâmpsia precoce e total após introdução do rastreio universal e uso profilático de aspirina. A redução da pré-eclâmpsia precoce foi estatisticamente significativa. Conclusão A associação de um modelo de rastreio combinado no primeiro trimestre com o uso profilático de aspirina é aparentemente eficaz na redução do risco de préeclâmpsia precoce.
