Summary

Preeclampsia (PE) affects from 2 to 8% of pregnant women. Recent studies show that prevention is the best strategy to improve perinatal outcomes. Therefore, the development of new strategies for preeclampsia screening becomes essential in order to determine the individual risk for each patient, and thus, to identify those who would be candidates for receiving prophylactic treatment with low-dose aspirin from the first trimester of pregnancy. The aim of our study is to determine prospectively, during clinical practice, the predictive and preventive capacity of a model of preeclampsia sequential screening in the first trimester of pregnancy.

This is a prospective, multicentre, cohort study, with the collaboration of Hospital de la Santa Creu i Sant Pau (Barcelona), Hospital Universitario de Cruces (Bilbao), Hospital Son Llàtzer (Mallorca) and Hospital Clínico Universitario Lozano Blesa (Zaragoza). Women with a singleton pregnancy attending to the 12-week ultrasound scan at one of the maternity hospitals participating in the study between March 1st 2021 and 30th October 2021 will be recruited. Patients who accept to participate in the study will be classified into three risk groups (low-risk, moderate-risk and high risk) based on medical history, Mean Arterial Pressure (MAP), Pregnancy-Associated Plasma Protein A (PAPP-A) and Uterine Artery Pulsatility Index (UTPI). Placental Growth Factor (PlGF) will only be determined in those patients classified as intermediate risk after this first step and then reclassified in high and low-risk patients depending on its values. The number of first-trimester scans performed by these hospitals is approximately 8200 patients annually. Due to PE prevalence in our environment is around 3% of the total population, a total of 246 cases of PE are to be expected. Therefore, based on similar previous experiences, we could assume that 80% of the patients will accept to participate in the study, meaning a total sample of 6560 pregnant women.
