Identifying pre-eclampsia risk factors early is crucial. Combining markers like uterine artery Doppler and hCG assays shows promise for screening, with low-dose aspirin as a potential preventive treatment.

Area of Science:

  • Obstetrics and Gynecology
  • Maternal-Fetal Medicine
  • Clinical Diagnostics

Background:

  • Pre-eclampsia poses significant risks to maternal and fetal health.
  • Early identification of high-risk pregnancies is essential for timely intervention.
  • Current screening methods for pre-eclampsia have limitations in sensitivity, specificity, or practicality.

Purpose of the Study:

  • To evaluate the effectiveness of various markers and risk factors for early pre-eclampsia screening.
  • To explore combinations of diagnostic tests for improved predictive value.
  • To lay the groundwork for evidence-based prevention strategies.

Main Methods:

  • Review of patient-related factors including parity and medical history.
  • Analysis of biological markers and their diagnostic utility.

  • Assessment of Doppler exploration of uterine arteries at mid-gestation.
  • Evaluation of combined testing strategies, such as hCG assay and Doppler ultrasound.

    • Main Results:

    • While multiparous patients with a history of severe pre-eclampsia are high-risk, nulliparous women also represent a susceptible group.
    • No single biological marker or assay currently meets all requirements for effective pre-eclampsia screening due to issues with sensitivity, specificity, invasiveness, or cost.
    • Uterine artery Doppler exploration shows satisfactory sensitivity and specificity, with persistence of a bilateral notch beyond 24 weeks significantly reducing false positives and indicating a high likelihood of developing hypertension.
    • A combination of second-trimester hCG assay and uterine artery Doppler exploration appears promising for improved screening.

    Conclusions:

    • Effective early screening for pre-eclampsia may require a combination of diagnostic markers and risk factor assessment.
    • Low-dose aspirin is the only current evidence-based preventive treatment for pre-eclampsia.
    • Further clinical trials are necessary to validate predictive strategies and assess the impact of interventions like low-dose aspirin compared to placebo.
