Vascular Inflammatory Genes as Predictors of Preeclampsia: A Systematic Review

Area of Science:

• Obstetrics and Gynecology
• Genetics
• Immunology

Background:

• Preeclampsia is a serious pregnancy complication characterized by hypertension and proteinuria.
• Its development involves complex interactions of vascular inflammation and angiogenic imbalance.
• Key candidate genes in vascular inflammation include VEGF, TNF-α, IL-10, and LPL.

Purpose of the Study:

• To systematically review and meta-analyze the association between specific genetic variants in VEGF, TNF-α, IL-10, and LPL genes and the risk of preeclampsia.
• To elucidate the role of these vascular inflammatory genes in the pathogenesis of preeclampsia.

Main Methods:

• A comprehensive literature search was performed across PubMed, Embase, and Cochrane databases.
• Case-control and cohort studies investigating the association between genetic variants and preeclampsia were included.
• Meta-analysis was used to pool data and calculate odds ratios for identified genetic polymorphisms.

Main Results:

• Significant associations were found between preeclampsia and polymorphisms in VEGF, TNF-α, IL-10, and LPL genes.
• Increased risk of preeclampsia was associated with specific variants: VEGF -2578C>A, VEGF -1154G>A, TNF-α -308G>A, IL-10 -819C>T, and LPL Ser447Ter.
• Pooled odds ratios indicated a genetic predisposition conferred by these variants.

Conclusions:

• Genetic variations in vascular inflammatory pathways contribute to preeclampsia development.
• Identified gene polymorphisms may serve as potential targets for early preeclampsia detection and therapeutic interventions.
• Further research is needed to understand the molecular mechanisms and develop targeted prevention strategies.
