Diagnosis of sepsis-induced disseminated intravascular coagulation and coagulopathy

Area of Science:

• Critical Care Medicine
• Hematology
• Infectious Diseases

Background:

• Disseminated intravascular coagulation (DIC) is a common and life-threatening complication of sepsis, significantly increasing mortality.
• Coagulation disorders in sepsis are linked to organ dysfunction, emphasizing the need for early detection.
• Existing diagnostic criteria for sepsis-associated DIC vary, impacting timely treatment initiation.

Purpose of the Study:

• To review and compare major diagnostic criteria for sepsis-associated DIC.
• To discuss the strengths and weaknesses of JAAM DIC, ISTH overt-DIC, and sepsis-induced coagulopathy criteria.
• To highlight the implications of differing criteria for clinical practice and treatment.

Main Methods:

• Literature review of major DIC diagnostic criteria in sepsis.
• Comparative analysis of the Japanese Association for Acute Medicine (JAAM) DIC criteria and the International Society on Thrombosis and Haemostasis (ISTH) overt-DIC criteria.
• Introduction of sepsis-induced coagulopathy as a proposed early detection category.

Main Results:

• The JAAM DIC criteria facilitate earlier diagnosis and treatment initiation in Japan compared to the stricter ISTH overt-DIC criteria.
• Conceptual differences in treatment approaches contribute to the discrepancy between Japanese and international criteria.
• The ISTH has proposed 'sepsis-induced coagulopathy' to address the need for earlier detection of DIC in sepsis.

Conclusions:

• Understanding the differences between DIC diagnostic criteria is vital for effective sepsis management.
• The JAAM DIC criteria are valuable for early treatment initiation in sepsis-associated DIC.
• Further research and consensus on early DIC detection criteria are needed for global application in critical care.
