Protein C in thromboembolic disease.

R A Marlar

    Seminars in Thrombosis and Hemostasis
    |October 1, 1985
    PubMed
    Summary

    Human protein C is a key regulator of blood clotting. Deficiencies, both inherited and acquired, are linked to severe thrombosis, highlighting its critical role in preventing dangerous blood clots.

    Area of Science:

    • Biochemistry
    • Hematology
    • Molecular Biology

    Background:

    • Human protein C is a critical anticoagulant protein.
    • Congenital deficiencies of protein C are associated with a high risk of thromboembolic events.
    • Protein C plays a vital role in regulating coagulation pathways.

    Purpose of the Study:

    • To investigate the role of human protein C in both congenital and acquired thrombotic states.
    • To understand the clinical implications of protein C deficiency in various thrombotic conditions.
    • To emphasize the importance of protein C in maintaining hemostatic balance.

    Main Methods:

    • Review of clinical cases with congenital protein C deficiencies.
    • Analysis of protein C antigen and activity levels in patients with thrombotic complications.
    • Correlation of protein C levels with the severity of disseminated intravascular coagulation (DIC).

    Main Results:

    • Congenital protein C deficiency, especially homozygous deficiency, leads to severe thrombosis like purpura fulminans in newborns.
    • Patients with familial thrombotic complications exhibit abnormal protein C molecules or reduced levels.
    • Acquired deficiencies, including those during DIC and postsurgical states, show decreased protein C levels correlating with thrombosis severity.

    Conclusions:

    • Human protein C is essential for preventing thrombosis in both congenital and acquired deficiency states.
    • Maintaining adequate protein C levels is crucial for managing thromboembolic disorders.
    • Protein C replacement therapy is vital for survival in severe congenital deficiencies.
