[Physiopathology of pre-eclampsia]

Area of Science:

• Obstetrics and Gynecology
• Pathophysiology
• Maternal-Fetal Medicine

Context:

• Pre-eclampsia is a pregnancy-specific disorder with significant maternal and fetal risks.
• It is a leading cause of maternal mortality globally, particularly in developing nations.
• Understanding its pathogenesis is crucial for improving outcomes.

Purpose:

• To review the putative pathogenetic mechanisms of pre-eclampsia.
• To explore the complex interplay of factors contributing to the disorder.
• To highlight the challenges in fully understanding and managing pre-eclampsia.

Summary:

• Pre-eclampsia involves altered oxidative, coagulative, and vasomotor balance, potentially due to increased angiotensin II sensitivity, reduced vasodilator prostaglandins, sympathetic hyperactivity, and incomplete cytotrophoblast implantation.
• Clinical manifestations include hypertension, proteinuria, and sodium retention, stemming from generalized vasoconstriction, utero-placental ischemia, and endothelial damage.
• Genetic factors and polymorphisms are implicated in the predisposition to pre-eclampsia, with a potential hereditary component.

Impact:

• Identifies key physiological and genetic factors contributing to pre-eclampsia.
• Underscores the complexity and multifactorial nature of the disorder's pathogenesis.
• Emphasizes the need for further research to elucidate mechanisms and improve clinical management and risk prediction.
