Combined Screening for Early Detection of Pre-Eclampsia

Area of Science:

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

Background:

• Pre-eclampsia remains a significant cause of maternal and fetal mortality globally.
• The exact pathophysiology of pre-eclampsia is not fully understood.
• Timely prediction is crucial for initiating preventive therapies and improving outcomes.

Purpose of the Study:

• To review current research on strategies for the early prediction of pre-eclampsia.
• To highlight the superiority of combined biophysical and biochemical markers over other tests.
• To discuss emerging biomarkers like cell-free fetal DNA.

Main Methods:

• Review of current scientific literature on pre-eclampsia prediction.
• Analysis of established prediction strategies including maternal risk factors, mean maternal arterial pressure, and ultrasound parameters.
• Evaluation of novel biochemical markers, particularly cell-free fetal DNA.

Main Results:

• A combination of biophysical and biochemical markers demonstrates superior performance for early pre-eclampsia prediction.
• Cell-free fetal DNA quantification shows promise as an emerging predictive marker.
• Maternal risk factors, arterial pressure, and ultrasound parameters are key components in prediction strategies.

Conclusions:

• Integrated approaches using multiple markers offer the best strategy for early pre-eclampsia prediction.
• Cell-free fetal DNA represents a significant advancement in predicting pre-eclampsia.
• Improved prediction facilitates timely intervention, potentially reducing maternal and fetal mortality.
