Preeclampsia: The Need for a Biological Definition and Diagnosis

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine

Background:

• Traditional preeclampsia prevention relies on identifying early signs like hypertension and proteinuria.
• Preeclampsia is debated as an early stage of a continuum possibly leading to eclampsia.
• Existing criteria for preeclampsia are viewed as diagnostic, leading to ongoing debate and revisions.

Purpose of the Study:

• To reframe the understanding of preeclampsia criteria as screening tools rather than definitive diagnostic markers.
• To advocate for a research focus on improving screening and diagnostic methods for hypertensive disorders of pregnancy.
• To ultimately enhance management strategies for maternal and perinatal morbidity and mortality.

Main Methods:

• This commentary analyzes the current diagnostic and screening approaches for preeclampsia.
• It reviews the historical context and ongoing debates surrounding preeclampsia criteria.
• It proposes a shift in research focus towards better screening and diagnostic technologies.

Main Results:

• The current criteria for preeclampsia function more effectively as screening tests.
• There is a lack of definitive diagnostic criteria, leading to persistent clinical and research challenges.
• The focus on 'preeclampsia' as a diagnosis may obscure the primary goal of managing hypertensive disorders.

Conclusions:

• Preeclampsia criteria should be interpreted as screening indicators, not conclusive diagnoses.
• Future research must prioritize the development of superior screening and diagnostic tools for hypertensive disorders in pregnancy.
• Improving these methods is crucial for reducing maternal and perinatal complications and mortality.
