Laboratory determination of heparin cofactor II. 1986

L C Ezenagu, and J T Brandt

Heparin cofactor II (HC II) is a recently characterized protein that is capable of neutralizing thrombin but not activated factor X. Recent evidence suggests that it may be a physiologically important regulator of thrombin activity. We evaluated and modified a method for clinical laboratory determination of this protein and then utilized the method to analyze HC II activity in various clinical samples. Low levels were associated with liver disease, consumptive coagulopathy, and preeclampsia; normal levels were seen with uncomplicated pregnancy, oral anticoagulant therapy, hereditary antithrombin III (AT III) deficiency, and in 31 patients evaluated for a thrombotic tendency. Except in hereditary AT III deficiency, decreased HC II activity was associated with decreased AT III activity. The potential clinical role of this assay is discussed.

D011225	Pre-Eclampsia	A complication of PREGNANCY, characterized by a complex of symptoms including maternal HYPERTENSION and PROTEINURIA with or without pathological EDEMA. Symptoms may range between mild and severe. Pre-eclampsia usually occurs after the 20th week of gestation, but may develop before this time in the presence of trophoblastic disease.

D004211	Disseminated Intravascular Coagulation	A disorder characterized by procoagulant substances entering the general circulation causing a systemic thrombotic process. The activation of the clotting mechanism may arise from any of a number of disorders. A majority of the patients manifest skin lesions, sometimes leading to PURPURA FULMINANS.
