Summary

Antithrombin III activity significantly decreases in eclampsia. A threshold of 90% can predict eclamptic crises, aiding early intervention in hypertensive pregnancies with proteinuria.

Area of Science:

  • Obstetrics and Gynecology
  • Hematology
  • Perinatology

Context:

  • Eclampsia is a severe complication of pregnancy characterized by seizures.
  • Hypertensive disorders in pregnancy, including pre-eclampsia and eclampsia, pose significant risks to maternal and fetal health.
  • Antithrombin III (ATIII) is a crucial anticoagulant protein, and its levels may be altered in pregnancy complications.

Purpose:

  • To investigate the correlation between antithrombin III activity levels and the occurrence of eclampsia.
  • To establish a predictive threshold for antithrombin III activity to identify patients at high risk of eclamptic crises.
  • To determine the clinical utility of systematic ATIII activity measurement in hypertensive pregnancies with proteinuria.

Summary:

  • A significant decrease in antithrombin III activity was observed in patients with eclampsia (p < 0.0001).

  • An antithrombin III activity level of 90% was identified as a critical threshold.
  • Levels at or below 90% showed a 78.3% positive predictive value for eclampsia, while levels above 90% had a 98.7% negative predictive value.

    • Impact:

    • The 90% antithrombin III activity level serves as an alarm threshold for impending eclamptic crises.
    • Systematic determination of antithrombin III activity is recommended for all pregnancies complicated by hypertension and proteinuria.
    • This finding can improve the early detection and management of eclampsia, potentially reducing maternal morbidity and mortality.
