Preeclampsia: pathophysiology, diagnosis, and management

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine
• Nephrology

Background:

• Preeclampsia is a significant cause of maternal and fetal complications.
• Clinical differentiation from other hypertensive disorders of pregnancy can be challenging.

Purpose of the Study:

• To outline diagnostic criteria for preeclampsia.
• To discuss pathophysiological features and differentiating markers.
• To review management strategies and potential prophylactic treatments.

Main Methods:

• Clinical observation and laboratory test interpretation.
• Review of pathophysiological mechanisms.
• Evaluation of diagnostic and therapeutic interventions.

Main Results:

• Diagnostic signs include late gestation presentation, edema, proteinuria, hemoconcentration, hypoalbuminemia, liver/coagulation abnormalities, and elevated urate.
• Differentiating markers include decreased antithrombin III, increased serum iron/carboxyhemoglobin, and decreased urinary calcium.
• Pathophysiology involves reduced cardiac output and plasma volume, increased vascular resistance, and renal "endotheliosis".

Conclusions:

• Preeclampsia management involves timely delivery or antihypertensive medications.
• Magnesium sulfate is crucial for managing eclampsia.
• Aspirin prophylaxis may reduce preeclampsia incidence in high-risk populations, possibly via prostaglandin metabolism modulation.
