Insights
Disseminated intravascular coagulation (DIC) is a complex syndrome involving widespread clotting. Early diagnosis and treatment of underlying causes are crucial for improving patient outcomes in DIC.
Area of Science:
- Hematology
- Pathophysiology
- Clinical Medicine
Background:
- Disseminated intravascular coagulation (DIC) is an acquired syndrome of widespread intravascular coagulation.
- It is triggered by infectious or non-infectious insults, leading to endothelial dysfunction and microvascular thrombosis.
- Extracellular DNA and histones are implicated in DIC pathogenesis.
Purpose of the Study:
- To provide an updated overview of DIC pathophysiology, diagnosis, and management.
- To discuss future research directions in basic and clinical DIC studies.
Main Methods:
- Review of current literature and established diagnostic criteria.
- Discussion of the International Society on Thrombosis and Haemostasis (ISTH) diagnostic scoring system.
- Analysis of evidence-based treatment strategies recommended by ISTH.
Main Results:
- DIC involves inflammatory cytokine-initiated coagulation, impaired anticoagulation, and suppressed fibrinolysis.
- The ISTH DIC scoring system is validated across various clinical settings.
- Effective DIC management requires treating underlying conditions and implementing evidence-based strategies.
Conclusions:
- Understanding DIC pathophysiology, utilizing validated diagnostic tools, and adhering to evidence-based management are key.
- Future research should focus on advancing basic and clinical understanding of DIC.
Abstract:
Disseminated intravascular coagulation (DIC) is an acquired syndrome characterized by widespread intravascular activation of coagulation that can be caused by infectious insults (such as sepsis) and non-infectious insults (such as trauma). The main pathophysiological mechanisms of DIC are inflammatory cytokine-initiated activation of tissue factor-dependent coagulation, insufficient control of anticoagulant pathways and plasminogen activator inhibitor 1-mediated suppression of fibrinolysis. Together, these changes give rise to endothelial dysfunction and microvascular thrombosis, which can cause organ dysfunction and seriously affect patient prognosis. Recent observations have pointed to an important role for extracellular DNA and DNA-binding proteins, such as histones, in the pathogenesis of DIC. The International Society on Thrombosis and Haemostasis (ISTH) established a DIC diagnostic scoring system consisting of global haemostatic test parameters. This scoring system has now been well validated in diverse clinical settings. The theoretical cornerstone of DIC management is the specific and vigorous treatment of the underlying conditions, and DIC should be simultaneously managed to improve patient outcomes. The ISTH guidance for the treatment of DIC recommends treatment strategies that are based on current evidence. In this Primer, we provide an updated overview of the pathophysiology, diagnosis and management of DIC and discuss the future directions of basic and clinical research in this field.

Extrinsic and Intrinsic Pathways of Hemostasis
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...
