    Pregnant women with pre-eclampsia show higher erythrocyte aggregation and hematocrit. These changes correlate with plasma fibrinogen and blood pressure, potentially impacting intervillous blood flow.

    Area of Science:

    • Obstetrics and Gynecology
    • Hematology

    Background:

    • Pre-eclampsia is a serious pregnancy complication.
    • Understanding hematological changes in pre-eclampsia is crucial for maternal and fetal health.

    Purpose of the Study:

    • To investigate erythrocyte aggregation and hematocrit levels in pregnancies complicated by pre-eclampsia.
    • To explore correlations between these hematological parameters and clinical factors.

    Main Methods:

    • Erythrocyte aggregation and hematocrit were measured in 155 uncomplicated pregnancies and 55 pregnancies with pre-eclampsia.
    • Correlations with plasma fibrinogen, mean arterial blood pressure, and peripheral vascular resistance were analyzed.

    Main Results:

    • Women with pre-eclampsia exhibited significantly increased erythrocyte aggregation and higher hematocrit compared to normal pregnancies.

  • Erythrocyte aggregation strongly correlated with plasma fibrinogen levels (r = 0.74).
  • Hematocrit correlated with mean arterial blood pressure (r = 0.69) and peripheral vascular resistance (r = 0.73).

    • Conclusions:

    • Elevated erythrocyte aggregation and hematocrit are characteristic hematological findings in pre-eclampsia.
    • These alterations may influence blood flow dynamics within the intervillous circulation.
    • The findings have potential clinical implications for managing pre-eclampsia.
