Pregnancy alters coagulation, increasing fibrinogen and D-dimer, but maintains haemostatic balance. HELLP syndrome shows distinct markers indicating intravascular coagulation.

Area of Science:

  • Obstetrics and Gynecology
  • Haematology
  • Physiology

Context:

  • Pregnancy involves significant physiological changes affecting the haemostatic system.
  • Understanding these changes is crucial for managing pregnancy-related complications.
  • Previous research has provided fragmented data on haemostasiological and haemorheological variables during gestation.

Purpose:

  • To systematically document changes in haemostasiological and haemorheological variables throughout pregnancy.
  • To compare these variables between uncomplicated pregnancies, pre-eclampsia, and HELLP syndrome.

Summary:

  • A longitudinal study tracked 125 pregnant women (25-40 weeks gestation).
  • Fibrinogen, D-Dimer, Factor VIIIR:Ag, erythrocyte aggregation, and plasma viscosity increased significantly during pregnancy.

  • Antithrombin III and alpha 2-antiplasmin remained stable. No significant differences were noted in pre-eclampsia compared to controls.
  • HELLP syndrome was associated with elevated D-Dimer, TAT, and decreased antithrombin III, protein C, and platelets.

    • Impact:

    • Demonstrates that pregnancy-induced coagulation alterations do not disrupt overall haemostatic balance in most cases.
    • Highlights specific coagulation abnormalities in HELLP syndrome, suggesting an increased tendency for intravascular coagulation.
    • Provides a comprehensive dataset for future research on pregnancy-related haemostasis and thrombotic disorders.
