Disseminated intravascular coagulation

Area of Science:

• Hematology
• Pathophysiology
• Clinical Diagnostics

Background:

• Disseminated intravascular coagulation (DIC) is a complex syndrome characterized by widespread activation of coagulation and fibrinolysis.
• Historically diagnosed via microthrombi detection, current methods focus on laboratory assessment of hemostatic abnormalities.
• DIC results from an imbalance between procoagulant and anticoagulant factors, leading to hypercoagulability and hyperfibrinolysis.

Purpose of the Study:

• To review the diagnostic approaches for disseminated intravascular coagulation (DIC).
• To differentiate between overt-DIC and non-overt-DIC stages.
• To explore potential therapeutic strategies for DIC.

Main Methods:

• Review of current diagnostic criteria for overt-DIC, including International Society of Thrombosis Haemostasis (ISTH) guidelines.
• Discussion of the challenges in diagnosing non-overt-DIC due to lack of established criteria.
• Examination of emerging treatment modalities for DIC.

Main Results:

• Overt-DIC diagnosis is guided by established criteria, while non-overt-DIC lacks specific diagnostic standards.
• Laboratory assessment of hemostatic abnormalities is central to current DIC diagnosis.
• Limited evidence-based treatments exist, but activated protein C (APC) and low-molecular-weight heparin show therapeutic potential.

Conclusions:

• Accurate diagnosis of DIC, particularly the non-overt stage, remains a clinical challenge.
• Further research is needed to establish diagnostic criteria for non-overt-DIC.
• Activated protein C (APC) and low-molecular-weight heparin represent promising avenues for DIC management.
