[Review. Endotoxins and blood coagulation]
Folia Haematologica (Leipzig, Germany : 1928)
|January 1, 1981
Summary
Endotoxins (ET) trigger blood coagulation by activating factor XII and the intrinsic pathway. This survey details ET-induced platelet damage, leukocyte procoagulant release, endothelial cell injury, and complement system interactions, leading to disseminated intravascular coagulation (DIC).
Area of Science:
- Hematology
- Immunology
- Pathophysiology
Context:
- Endotoxins (ET) are potent activators of the coagulation cascade.
- Understanding ET's role in hemostasis is crucial for managing sepsis and related complications.
- This study surveys the intricate mechanisms linking ET to coagulation disorders.
Purpose:
- To elucidate the impact of endotoxins on blood coagulation.
- To detail the activation of intrinsic and extrinsic coagulation pathways by ET.
- To describe ET-induced platelet and endothelial cell damage.
Summary:
- Endotoxins activate factor XII, initiating the intrinsic coagulation pathway.
- ET induce leukocyte procoagulant liberation and platelet damage, leading to thrombocytopenia.
- Endothelial cell injury and complement activation are discussed, alongside the role of leukocyte procoagulant in disseminated intravascular coagulation (DIC).
Impact:
- Provides a comprehensive overview of endotoxin-mediated coagulation.
- Highlights key mechanisms in the pathogenesis of DIC.
- Informs potential therapeutic strategies targeting endotoxin-induced coagulopathy.
