History of Disseminated Intravascular Coagulation (DIC) Research and My Personal Research History

Area of Science:

• Hematology
• Critical Care Medicine
• Pathophysiology

Background:

• Disseminated intravascular coagulation (DIC) is a critical condition characterized by systemic micro-clot formation and bleeding.
• Its pathogenesis involves complex interactions including coagulation/fibrinolysis imbalance, endothelial damage, and inflammation.
• Despite decades of study, the exact mechanisms and optimal management of DIC remain unclear.

Purpose of the Study:

• To review the current understanding of disseminated intravascular coagulation (DIC) pathogenesis.
• To discuss diagnostic challenges and evolving criteria for DIC, particularly sepsis-associated DIC.
• To explore current treatment strategies and emerging therapeutic approaches for DIC.

Main Methods:

• Literature review of DIC pathogenesis, diagnosis, and treatment.
• Analysis of diagnostic criteria, including the Sepsis-Induced Coagulopathy (SIC) and overt DIC criteria.
• Examination of current treatment recommendations and investigational therapies, such as anticoagulation.

Main Results:

• DIC diagnosis is established, but its precise mechanisms are not fully elucidated.
• Several diagnostic criteria exist, with a two-step approach recommended for sepsis-associated DIC (SIC followed by overt DIC).
• Current treatment primarily addresses underlying diseases, with limited specific interventions for DIC itself.

Conclusions:

• DIC remains a challenging clinical entity with incomplete understanding of its pathophysiology.
• Early diagnosis via SIC criteria is crucial for managing sepsis-associated DIC.
• Further research into targeted therapies, including anticoagulation for early-phase DIC, is warranted.
