PP008. Lipotoxicity and preeclampsia: A probable correlation (preliminary results)

Area of Science:

• Obstetrics and Gynecology
• Metabolic Disorders
• Cardiovascular Health

Background:

• Preeclampsia (PE) is a global concern with unclear causes, though obesity is a significant risk factor.
• Studies indicate that a Body Mass Index (BMI) over 30 increases PE risk, with higher BMIs posing even greater risks.
• Intracellular triglyceride accumulation may lead to mitochondrial dysfunction, increased reactive oxygen species (ROS), and endothelial damage.

Purpose of the Study:

• To compare the incidence of potential lipotoxicity markers between pregnant women with and without preeclampsia.
• Investigate the association between obesity, lipid profiles, and preeclampsia development.

Main Methods:

• A case-control study involving 27 preeclamptic and 27 normal pregnant women.
• Exclusion criteria included collagen diseases, smoking, diabetes, twin pregnancy, and fetal malformations.
• Blood samples analyzed for BMI, cholesterol, glucose, triglycerides, and C-reactive protein; data analyzed using odds ratio.

Main Results:

• Preeclamptic women more frequently had BMI > 30, triglycerides > 150, and LDL cholesterol > 100.
• No significant differences were observed in age, glucose levels, or HDL cholesterol between the groups.
• These findings suggest a link between specific lipotoxicity markers and preeclampsia.

Conclusions:

• Lipotoxicity in pregnancy impairs trophoblastic invasion, leading to maternal endothelial and placental dysfunction, contributing to PE pathophysiology.
• Monitoring obese patients or those with lipid disorders pre-conception is crucial for PE prevention.
• Management strategies should include advising on optimal conception timing and lifestyle modifications.
