Introduction

Disseminated Intravascular Coagulation (DIC) is a complex and paradoxical medical condition characterized by simultaneous clotting and bleeding throughout the body. Often triggered by severe infections, trauma, malignancies, or obstetric complications, DIC represents a critical disruption in the body’s hemostatic balance. The paradox lies in the concurrent activation of coagulation pathways and consumption of clotting factors, leading to both thrombosis and hemorrhage—a dual threat that can rapidly escalate to multi-organ failure and death if not promptly managed [1].

At the heart of DIC is the systemic activation of the coagulation cascade. Normally, this cascade is tightly regulated to prevent excessive clotting or bleeding. In DIC, however, procoagulant stimuli—such as tissue factor released from damaged cells—trigger widespread thrombin generation. This leads to fibrin deposition in the microvasculature, causing microthrombi that obstruct blood flow and damage organs. Simultaneously, the body’s natural anticoagulant mechanisms, including antithrombin III and protein C, are overwhelmed or depleted. Fibrinolysis, the process that breaks down clots, is also suppressed. As clotting factors and platelets are consumed, the patient becomes prone to bleeding, even in the absence of trauma [2].

The cornerstone of DIC management is treating the underlying cause. Supportive care includes: Platelets, fresh frozen plasma, and cryoprecipitate may be administered to correct bleeding. In selected cases, low-dose heparin may be used to prevent thrombosis, especially in chronic DIC or when thrombosis predominates. Agents like tranexamic acid are controversial and generally avoided unless bleeding is life-threatening and fibrinolysis is excessive. Close monitoring of coagulation parameters and organ function is essential. In sepsis-induced DIC, early antibiotic therapy and hemodynamic support are critical. DIC is not a primary disease but a secondary complication of various underlying conditions. Common triggers include: The most frequent cause, especially in gram-negative bacterial infections, where endotoxins stimulate massive cytokine release and coagulation activation. Severe injuries can release tissue factor and cause endothelial damage, initiating DIC. Particularly acute promyelocytic leukemia and solid tumors, which may chronically activate coagulation pathways [3].

Conditions like placental abruption, amniotic fluid embolism, and preeclampsia are known precipitants. The presentation of DIC varies depending on the balance between clotting and bleeding. In acute DIC, patients may exhibit: Petechiae, ecchymoses, and mucosal bleeding, Hematuria and gastrointestinal bleeding, Respiratory distress due to pulmonary microthrombi [4].

Chronic DIC, often seen in cancer patients, may be asymptomatic or present with mild thrombosis and bleeding episodes. Diagnosing DIC requires a combination of clinical suspicion and laboratory findings. The International Society on Thrombosis and Hemostasis (ISTH) has proposed a scoring system based on: However, these markers are not specific to DIC and may overlap with other coagulopathies. Therefore, diagnosis must be contextualized within the patient’s clinical scenario [5].

Conclusion

Recent research has highlighted the role of the immune system in DIC pathogenesis. Damage-associated molecular patterns (DAMPs) and pathogen-associated molecular patterns (PAMPs) activate immune cells, which in turn release pro-inflammatory cytokines. These cytokines promote tissue factor expression and endothelial injury, further amplifying coagulation. Histones released from dying cells have also been implicated in promoting thrombosis and suppressing fibrinolysis. DIC carries a high mortality rate, particularly in acute settings. Outcomes depend on the severity of the underlying condition, the extent of organ involvement, and the timeliness of intervention. Chronic DIC may have a more indolent course but still poses significant risks if left untreated. Advancements in understanding the molecular and immunological underpinnings of DIC are paving the way for targeted therapies. Biomarkers for early detection, personalized anticoagulant strategies, and modulation of immune-coagulation crosstalk are areas of active research. The development of individualized diagnostic criteria, especially for non-overt DIC, may improve early recognition and outcomes.
