Maternal Immune Cell and Cytokine Profiles to Predict Cardiovascular Risk Six Months after Preeclampsia

Area of Science:

• Immunology
• Cardiovascular Disease Research
• Reproductive Health

Background:

• Preeclampsia (PE) significantly increases women's long-term cardiovascular disease (CVD) risk.
• Early identification of high-risk individuals post-PE for CVD screening is challenging.
• Immune system alterations following PE may offer insights into future CVD risk.

Purpose of the Study:

• To evaluate if immune cell and cytokine profiles post-PE can distinguish between low and high CVD risk at 6-months postpartum.
• To identify potential immune biomarkers for early CVD risk stratification in women with a history of PE.

Main Methods:

• Prospective study of 31 women who developed PE.
• Immune cell phenotyping and plasma cytokine quantification at delivery, 3-months, and 6-months postpartum.
• Assessment of lifetime CVD risk at 6-months postpartum and comparison of immune profiles between risk groups.

Main Results:

• 18 participants (58.1%) showed high CVD risk at 6-months postpartum.
• Lower NK-cells at delivery (p=0.04) and altered T-cell subsets (FoxP3+, CD8+, CD4+:CD8+ ratio) at 3-months postpartum in high-risk group.
• No significant differences in immune cells at 6-months postpartum or cytokine levels at any time point.

Conclusions:

• Subtle postpartum immune cell profile changes may indicate future CVD risk in women with PE history.
• Immune cell phenotyping in the early postpartum period shows potential for distinguishing CVD risk levels.
• Further research is needed to validate these immune markers for clinical application in CVD risk assessment.
