Advances in the Diagnosis of DIC and Fibrinolysis

Disseminated intravascular coagulation (DIC) represents a critical clinical syndrome characterized by systemic activation of coagulation pathways and concurrent dysregulation of fibrinolysis. It commonly arises as a complication of severe infections, trauma, malignancies, or obstetric emergencies. Fibrinolysis, the physiological mechanism responsible for clot breakdown, is often impaired in DIC, exacerbating the risk of microvascular thrombosis and organ dysfunction. Over the past decade, significant strides have been made in the early recognition and diagnosis of DIC and its fibrinolytic disturbances. Modern scoring systems—such as those by ISTH and JAAM—integrate laboratory and clinical variables to guide diagnosis with improved specificity and sensitivity. Concurrently, biomarker discovery, including D-dimer, thrombin-antithrombin complexes, and histone-DNA complexes, has enriched diagnostic precision. Technological innovations like thromboelastography (TEG), rotational thromboelastometry (ROTEM), and clot waveform analysis (CWA) offer dynamic, bedside insights into coagulation and fibrinolysis. Moreover, the role of molecular triggers such as DAMPs, PAMPs, and NETs in modulating coagulation is being increasingly appreciated. Imaging modalities like Doppler ultrasound and CT angiography have also augmented diagnostic capabilities by identifying microvascular thrombi. This review outlines these advances, with emphasis on integrating biomarkers, point-of-care technologies, and scoring systems to optimize the diagnosis and management of DIC and fibrinolysis abnormalities. Disseminated intravascular coagulation (DIC) is a complex and life-threatening disorder characterized by widespread activation of coagulation and fibrinolytic pathways, leading to excessive consumption of clotting factors and platelets, as well as microvascular thrombosis and organ dysfunction. In recent years, there have been significant advances in the diagnosis of DIC, allowing for earlier recognition and improved management of patients with this condition. Key recent advances include refined scoring systems, the identification of novel biomarkers, and the exploration of advanced imaging techniques.
