[Classifying types of DIC: clinical features and animal models]
1Department of Internal Medicine (III), Kanazawa University School of Medicine.
Summary
Disseminated intravascular coagulation (DIC) is a complex condition with distinct types. Understanding these types, like suppressed-fibrinolytic DIC in sepsis, aids in tailored treatment selection.
Area of Science:
- Pathophysiology of hemostasis
- Hematology
- Internal Medicine
Context:
- Disseminated intravascular coagulation (DIC) is a critical condition characterized by widespread coagulation activation.
- DIC presents with varying degrees of fibrinolytic activation alongside systemic coagulation.
- The underlying disease significantly influences the type of DIC observed.
Purpose:
- To delineate the distinct types of disseminated intravascular coagulation (DIC).
- To correlate specific underlying conditions with distinct DIC phenotypes.
- To highlight the role of fibrinolytic activation in classifying DIC.
Summary:
- Suppressed-fibrinolytic DIC, common in sepsis, shows severe coagulation and mild fibrinolysis.
- Enhanced-fibrinolytic DIC, associated with acute promyelocytic leukemia (APL), involves severe activation of both coagulation and fibrinolysis.
- Balanced-fibrinolytic DIC, often seen in solid tumors, presents an intermediate activation profile.
Impact:
- Classifying DIC into distinct types facilitates more precise therapeutic strategies.
- Animal models of DIC (LPS-induced vs. TF-induced) mimic distinct human DIC subtypes.
- This classification advances the development of targeted treatments for DIC based on its specific type.

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.

15.1K
Blood clotting or coagulation involves extrinsic and intrinsic pathways, which ultimately merge into the common pathway, forming a fibrin clot.
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...
