Preeclampsia and the Kidney: Pathophysiology and Clinical Implications

Area of Science:

• Physiology
• Pathophysiology
• Obstetrics

Background:

• Hypertensive disorders of pregnancy, including preeclampsia, are leading causes of maternal morbidity and mortality globally.
• Pregnancy involves significant physiological adaptations crucial for placental and fetal development.
• Preeclampsia presents a complex interplay of factors affecting maternal health.

Purpose of the Study:

• To review the physiological changes during pregnancy.
• To explore proposed mechanisms underlying preeclampsia development.
• To highlight the clinical implications and long-term health consequences of preeclampsia.

Main Methods:

• Review of existing literature on pregnancy physiology and preeclampsia pathophysiology.
• Synthesis of proposed etiological mechanisms.
• Analysis of clinical outcomes and long-term risks associated with hypertensive disorders of pregnancy.

Main Results:

• Pregnancy involves adaptations for placental and fetal development.
• Multiple mechanisms contribute to preeclampsia, including abnormal placentation, inflammation, immune imbalance, and endothelial dysfunction.
• Preeclampsia increases risks for preterm delivery, maternal/fetal mortality, acute kidney injury, and long-term cardiovascular and kidney disease.

Conclusions:

• Understanding normal pregnancy physiology and preeclampsia pathophysiology is crucial.
• Effective management and novel treatment strategies require a comprehensive grasp of the disease.
• Addressing preeclampsia is vital for reducing maternal and fetal morbidity and mortality.
