The Link Between Preeclampsia and the Immune System

Preeclampsia is a complex pregnancy complication that affects both maternal and fetal health. Characterized by high blood pressure and protein in the urine, it usually develops after the 20th week of pregnancy and can have serious consequences if left untreated. Understanding the immune system’s role in preeclampsia is crucial for identifying at-risk pregnancies and monitoring potential complications.

Experts at ICPRM (Dr. Raut's Centre for Reproductive Immunology) study the immunological factors and risk markers associated with preeclampsia to provide insights into its causes, symptoms, and potential interventions. By understanding how the immune system contributes to the development of preeclampsia, ICPRM is able to offer targeted immunology-based treatments that address these underlying issues. This approach helps safeguard maternal health, enabling more precise management of preeclampsia and improving pregnancy outcomes.

What Causes Preeclampsia?

Preeclampsia is a condition influenced by multiple factors, including the immune system, maternal health, and genetics. Understanding these causes is essential for early detection, monitoring, and timely intervention to protect both mother and baby.

• Immunological Factors: Abnormal immune responses, including T cell activation and cytokine imbalances, can impair placental development and trigger inflammation. These disruptions may reduce blood flow to the placenta, playing a key role in the onset of preeclampsia.
• First Pregnancies: Women experiencing their first pregnancy are at higher risk due to the body’s initial adaptation to pregnancy-related immune and vascular changes.
• Multiple Pregnancies: Carrying twins, triplets, or more increases the strain on the maternal body, elevating the risk of high blood pressure and related complications.
• Obesity: Excess body weight and associated metabolic issues can contribute to inflammation and higher blood pressure, increasing susceptibility to preeclampsia.
• Pre-existing Hypertension: Chronic high blood pressure before pregnancy can worsen during gestation, making preeclampsia more likely.
• Genetic Predisposition: A family history of preeclampsia can increase the chances of developing the condition in subsequent pregnancies.
• Other Medical Conditions: Diabetes, kidney disease, and autoimmune disorders can also elevate the risk by affecting vascular and immune function.

Types of Preeclampsia

Preeclampsia can present in different forms, depending on its severity, onset, and the organs affected. Understanding the types of preeclampsia is crucial for effective monitoring and intervention.

• Mild Preeclampsia: This form is characterized by slightly elevated blood pressure and mild proteinuria (presence of protein in urine). Symptoms are often subtle and may include mild swelling in the hands, feet, or face, and occasional headaches. While mild, it still requires regular monitoring to prevent progression to more severe forms.
• Severe Preeclampsia: In severe cases, blood pressure rises significantly, and protein levels in urine are high. This type can affect multiple organs, leading to symptoms such as severe headaches, visual disturbances, liver or kidney dysfunction, and swelling in various parts of the body. Severe preeclampsia increases the risk of complications for both mother and baby and often requires immediate medical intervention, including hospitalization.
• Early-Onset vs. Late-Onset Preeclampsia:

1. Early-Onset: Occurs before 34 weeks of pregnancy and is often associated with more severe complications for both mother and fetus. Early-onset preeclampsia may lead to restricted fetal growth and requires close monitoring, frequent check-ups, and sometimes early delivery to ensure safety.
2. Late-Onset: Develops after 34 weeks and is generally less severe but still requires careful observation. Late-onset preeclampsia can still pose risks such as preterm birth, placental complications, or organ stress in the mother.

Immunology-Based Treatment at ICPRM

Preeclampsia is increasingly linked to immune system imbalances, including abnormal T cell activation, cytokine disruptions, and other immunological disturbances that affect placental development and maternal-fetal health. Addressing these underlying immune factors is critical for effective management. Key immunology-based strategies include:

• Immunomodulatory Medications: Medications that help balance immune responses, reduce inflammation, and support healthy placental function.
• Active Immunotherapy: Techniques like Lymphocyte Immunization Therapy (ImmuLIT®), which help modulate maternal immune tolerance and reduce immune-mediated complications.
• Monitoring Immune Markers: Regular assessment of cytokines, T cell activity, and other immunological markers to identify and manage high-risk pregnancies early.
• Personalized Protocols: Combining immune-targeted treatments with conventional management (blood pressure control, fetal monitoring, and lifestyle guidance) for a comprehensive approach.

These immunology-focused treatments target the root causes of preeclampsia, improving maternal and fetal outcomes. At ICPRM, this approach is delivered through ImmuLIT®, an immunomodulatory therapy combined with specialized medications, offering a precise and advanced solution for pregnancies affected by immune disturbances.

Conclusion

Preeclampsia is a serious pregnancy complication influenced by both maternal health and immunological factors. Understanding the role of the immune system, including T cells, cytokines, and other immunological contributors, is essential for early detection, timely intervention, and minimizing risks for both mother and baby.

At ICPRM (Dr. Raut's Centre for Reproductive Immunology), specialists combine clinical expertise with advanced immunology-based approaches, including ImmuLIT®, to offer personalized care and monitoring. By addressing both physiological and immune-related factors, ICPRM helps expecting mothers navigate preeclampsia safely, improving pregnancy outcomes and overall maternal-fetal well-being.
