Overview
Disseminated intravascular coagulation, is a pathological process in the body where the blood starts to coagulate throughout the whole body. This depletes the body of its platelets and coagulation factors, and there is a paradoxically increased risk of hemorrhage. It occurs in critically ill patients, especially those with Gram-negative sepsis (particularly meningococcal sepsis) and acute promyelocytic leukemia. DIC is a complex and highly variable disorder, whose manifestations depend upon the inciting event, the host response and underlying comorbid disease. Additionally, the morbidity and mortality in patients with DIC often depends more on the underlying disease and he specific pathophysiology. As such, well-designed studies are obviously difficult to design, and there is therefore little consensus regarding management. The term DIC has evolved from the terms ‘consumptive coagulopathy’ and later, ‘defibrination syndrome’. Although most physicians are aware of the hemorrhage that is seen in patients with DIC, the ‘coagulation’ in DIC actually refers to both hemorrhage and thrombosis. In actuality, the thrombosis, both micro and macro-vascular, with resulting ischemia, contributes more to morbidity and mortality than the hemorrhage. Bick defines DIC as ‘a systemic thrombohemorrhagic disorder seen in association with well-defined clinical situations AND laboratory evidence for procoagulant activation, fibrinolytic activation, inhibitor consumption, and evidence of end-organ damage’.
Historical Perspective
The syndrome of DIC is well known in the medical literature for centuries, although a more precise description of the underlying mechanisms had to await the 20th century. Initial ideas on a role of the contact activation system as the primary trigger for the systemic activation of coagulation as well as a presumed hyperfibrinolytic response in DIC have been found to be misconceptions.
Classification
Disseminated intravascular coagulation may be classified according to the degree of fibrinolytic activation into suppressed-fibrinolytic-type DIC (DIC with suppressed fibrinolysis), enhanced-fibrinolytic-type DIC (DIC with enhanced fibrinolysis) and balanced-fibrinolytic-type DIC (DIC with balanced fibrinolysis). Each type differs in clinical features and laboratory findings.
Pathophysiology
DIC is a hemorrhagic syndrome originating in the small blood vessels. DIC is caused by uncontrolled activation of clotting factors and fibrinolytic enzymes. Tissue necrosis and bleeding are consequences of DIC. Under homeostatic conditions, the body is maintained in a finely tuned balance of coagulation and fibrinolysis. The activation of the coagulation cascade yields thrombin that converts fibrinogen to fibrin; the stable fibrin clot being the final product of hemostasis. The fibrinolytic system then functions to break down fibrinogen and fibrin. Activation of the fibrinolytic system generates plasmin (in the presence of thrombin), which is responsible for the lysis of fibrin clots. The breakdown of fibrinogen and fibrin results in polypeptides called fibrin degradation products (FDPs) or fibrin split products (FSPs). In a state of homeostasis, the presence of thrombin is critical, as it is the central proteolytic enzyme of coagulation and is also necessary for the breakdown of clots, or fibrinolysis.
Causes
There are a variety of causes of DIC, all usually causing the release of chemicals into the blood that instigates the coagulation. Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated. Disseminated intravascular coagulation in itself is a life-threatening condition and must be treated as such irrespective of the cause. Common causes include abruptio placentae, amniotic fluid embolism, aortic aneurysm, blood transfusion reaction, drugs (e.g. Amphetamines), beractant eclampsia, giant hemangioma, graft-versus-host disease, HELLP syndrome and hemolytic transfusion reaction.
Disseminated intravascular coagulation (DIC) must be differentiated from other diseases that cause symptoms of DVT and pulmonary embolism such as: factor V Leiden mutation, protein C deficiency, protein S deficiency, prothrombin gene mutation, antithrombin III deficiency, antiphospholipid antibody syndrome.
Epidemiology and Demographics
The incidence of DIC is different in different diseases as it is almost always related to a life threatening condition. It depends on the cause of DIC such as cancer, infection, trauma and Obstetrical complications. The incidence of DIC is different in different diseases as it is almost always related to a life threatening condition. It depends on the cause of DIC such as cancer, infection, trauma and obstetrical complications. The prevalence of DIC depends on the clinical settings, higher versus low acquity settings. The data sometimes may underestimate the incidence of trasient or mild cases of DIC.
Risk Factors
Common risk factors in the development of DIC include trauma, sepsis, obstetric complications, cancers, and immunologic reactions
Natural History, Complications and Prognosis
If left untreated, 40-80% patients with DIC may progress to develop organ dysfunction. Common complications of DIC include renal failure, hepatic dysfunction, acute lung injury, neurologic dysfunction and adrenal failure. Low levels of antithrombin at the onset if shock may predict an unfavorable prognosis.
Diagnosis
Diagnostic Study of Choice
There is no single diagnostic study of choice for DIC. DIC is a clinical as well as a laboratory diagnosis. DIC may be diagnosed based on the diagnostic criteria established by Japanese Society on Thrombosis and Hemostasis.
History and Symptoms
Patients with DIC may have a history of abruptio placentae, amniotic fluid embolism, aortic aneurysm, blood transfusion reaction, drugs (e.g. Amphetamines), beractant eclampsia, giant hemangioma, graft-versus-host disease, HELLP syndrome, hemolytic transfusion reaction, liver disease, malignancy (especially APL), sepsis (esp. gram-negative bacteria), severe allergic reaction, transplant rejection, trauma (e.g. Fat embolism, head injury), venomous snake and viral hemorrhagic fever.
Physical Examination
Common physical examination findings of DIC include signs of spontaneous and life-threatening hemorrhage, signs of subacute bleeding, signs of diffuse or localized thrombosis, bleeding into serouscavities, nonspecific altered consciousness or stupor, transient focal neurologic deficits, hypotension, tachycardia, circulatory collapse, pleural friction rub, signs of acute respiratory distress syndrome(ARDS), hematemesis, hematochezia, signs of azotemia and renal failure, acidosis, hematuria, oliguria, metrorrhagia and uterine hemorrhage.
Laboratory Findings
Laboratory findings consistent with the diagnosis of DIC include decreased platelets, fibrin degradation products or D-dimer tests (markers of fibrinolysis), bleeding time and fibrinogen levels. Peripheral smear shows schistocytes and RBC fragments in ~ 50%, mild reticulocytosis, leukocytosis, and thrombocytopenia with an increased population of young platelets (due to increased destruction and turnover). Clotting factors include normal prothrombin time and partial thromboplastin time in up to 50% of patients (due to higher circulating levels of clotting factors such as factor Xa and thrombin), elevated fibrin and fibrinogen degradation products. D-dimer more sensitive and specific for DIC. Antithrombin levels have become a key test for diagnosing and monitoring therapy in DIC.
Electrocardiogram
There are no specific ECG findings associated with DIC but it may cause thrombosis which may lead to recurrent ST-segment elevations in leads II, III, and aVF.
X-ray
There are no x-ray findings associated with DIC.
Echocardiography and Ultrasound
There are no echocardiography/ultrasound findings associated with DIC. However, an echocardiography/ultrasound may be helpful in the diagnosis of complications of DIC, which include myocardial infarction, pulmonary artery mass etc.
CT scan
There are no CT scan findings associated with DIC. CT scanning of the chest may reveal blood in the tracheobronchial tree or clots elsewhere in the body.
MRI
There are no MRI findings associated with DIC. However, sepsis induced DIC may show lesions predominated in the white matter, suggesting increased blood-brain barrier permeability.
Treatment
Medical Therapy
- There is no treatment for [disease name]; the mainstay of therapy is supportive care.
- The mainstay of therapy for [disease name] is [medical therapy 1] and [medical therapy 2].
- [Medical therapy 1] acts by [mechanism of action 1].
- Response to [medical therapy 1] can be monitored with [test/physical finding/imaging] every [frequency/duration].
Surgery
- Surgery is not the mainstay of therapy for DIC.
Prevention
- There are no established measures for the prevention of DIC. The threshold of initiation of prevention therapy for bleeding in DIC is a platelet count of ≥10,000/microL. Some studies suggest a platelet count of 20,000/microL without bleeding. There is little evidence to support preventive measures for thrombosis in DIC.

Overview
DIC is a hemorrhagic syndrome originating in the small blood vessels. DIC is caused by uncontrolled activation of clotting factors and fibrinolytic enzymes. Tissue necrosis and bleeding are consequences of DIC. Under homeostatic conditions, the body is maintained in a finely tuned balance of coagulation and fibrinolysis. The activation of the coagulation cascade yields thrombin that converts fibrinogen to fibrin; the stable fibrin clot being the final product of hemostasis. The fibrinolytic system then functions to break down fibrinogen and fibrin. Activation of the fibrinolytic system generates plasmin (in the presence of thrombin), which is responsible for the lysis of fibrin clots. The breakdown of fibrinogen and fibrin results in polypeptides called fibrin degradation products (FDPs) or fibrin split products (FSPs). In a state of homeostasis, the presence of thrombin is critical, as it is the central proteolytic enzyme of coagulation and is also necessary for the breakdown of clots, or fibrinolysis.
Pathophysiology
DIC is an acquired syndrome characterized by the intravascular activation of coagulation due to sepsis, trauma, malignancy, liver disease, obstetric disorders, envenomation, vascular anomalies and major transfusion reactions. It can originate from and cause damage to the microvasculature, which may eventually lead to organ dysfunction. Under homeostatic conditions, the body is maintained in a state of hematological equilibrium of coagulation and fibrinolysis termed as hemostasis. The activation of the coagulation cascade yields thrombin that converts fibrinogen to fibrin; the stable fibrin clot being the final product of coagulation cascade. The fibrinolytic system then functions to break down fibrinogen and fibrin. Activation of the fibrinolytic system generates plasmin (in the presence of thrombin), which is responsible for the lysis of fibrin clots. The breakdown of fibrinogen and fibrin results in polypeptides called fibrin degradation products (FDPs) or fibrin split products (FSPs).
DIC as a disease process
- DIC occurs secondary to a clinical disorder. The clinical spectrum includes sepsis, trauma, malignancy, liver disease, obstetric disorders, envenomation, vascular anomalies and major transfusion reactions.
- Ocurrence of DIC in a patient should always be seen as an indicator of another life-threatening condition and warrants thorough diagnostic evaluation.
Mediators of induction of DIC
- DIC may be induced by either or both of the following mechanisms:
- As a consequence of systemic inflammatory response, there is activation of cytokine network and thereby coagulation system as in sepsis or polytrauma and/or
- Release of pro-coagulant products into the blood stream such as in malignancies or obstetrical cases.
- In DIC, the processes of coagulation and fibrinolysis lose control, and the result is widespread clotting with resultant bleeding. Regardless of the triggering event of DIC, once initiated, the pathophysiology of DIC is similar in all conditions.[1] One critical mediator of DIC is the release of a transmembrane glycoprotein called tissue factor(TF).
- TF is present on the surface of many cell types (including endothelial cells, macrophages, and monocytes) and is not normally in contact with the general circulation, but is exposed to the circulation after vascular damage.
- For example, TF is released in response to exposure to cytokines (particularly interleukin), tumor necrosis factor, and endotoxin. This plays a major role in the development of DIC in septic conditions.
- TF is also abundant in tissues of the lungs, brain, and placenta. This helps to explain why DIC readily develops in patients with extensive trauma.
- Upon activation, TF binds with coagulation factors that then trigger both the intrinsic and the extrinsic pathways of coagulation.[2]
Activation of coagulation cascade
- Excess circulating thrombin results from the excess activation of the coagulation cascade.
- The excess thrombin cleaves fibrinogen, which ultimately leaves behind multiple fibrin clots in the circulation.
- These excess clots trap platelets to become larger clots, which leads to microvascular and macrovascular thrombosis.
- This lodging of clots in the microcirculation, in the large vessels, and in the organs is what leads to the ischemia, impaired organ perfusion, and end-organ damage that occurs with DIC.[3][4][5]
Consumptive coagulopathy and bleeding sequelae
- Coagulation inhibitors are also consumed in this process. Decreased inhibitor levels will permit more clotting so that a feedback system develops in which increased clotting leads to more clotting. At the same time, thrombocytopenia occurs because of the entrapment of platelets. Clotting factors are consumed in the development of multiple clots, which contributes to the bleeding seen with DIC.[6]
- Simultaneously, excess circulating thrombin assists in the conversion of plasminogen to plasmin, resulting in fibrinolysis. The breakdown of clots results in excess amounts of FDPs, which have powerful anticoagulant properties, contributing to hemorrhage.
- The excess plasmin also activates the complement and kinin systems.[7]
- Activation of these systems leads to many of the clinical symptoms that patients experiencing DIC exhibit, such as shock, hypotension, and increased vascular permeability. The acute form of DIC is considered an extreme expression of the intravascular coagulation process with a complete breakdown of the normal homeostatic boundaries.
- DIC is associated with a poor prognosis and a high mortality rate.
Summary
- It seems that the formation of both thrombin and plasmin are required for the development of DIC.
- A variety of triggering events can result in thrombin and plasmin formation, including damage to RBCs, platelets, or the endothelium.
- After the coagulation system has been activated, the pathophysiology of DIC is similar in all disorders.
- Circulating thrombin cleaves fibrinopeptides A and B from fibrinogen resulting in the formation of fibrin monomers.
- These monomers polymerize into a fibrin clot, which traps platelets and results in thrombosis, organ ischemia and thrombocytopenia.
- Thrombin also induces endothelial cells to release:
- endothelin, a potent vasoconstrictor, and,
- E selectin, which binds granulocytes and lymphocytes, resulting in further cytokine release as well as release of platelet activating factor.
- At the same time, plasmin cleaves the carboxy-terminal end of fibrinogen into fibrinogen degradation products, and cleaves fibrin into fibrin degradation products.
- The circulating FDPs (fibrin and fibrinogen) interfere with the polymerization of fibrin monomers, resulting in further hemorrhage.
- Additionally, the fibrinogen degradation products D and E impair platelet function, worsening the bleeding.
- The fibrin degradation products and D-dimer induce synthesis of IL-1 and IL-6, which cause further endothelial damage, as well as plasminogen activator inhibitor type 1 (PAI-1) which inhibits fibrinolysis resulting in accelerated thrombus formation.
- FDPs also stimulate the release of tissue factor, which accelerates thrombosis via the extrinsic coagulation pathway.
- The release of large amounts of tissue factor (i.e. in obstetrical cases) can also initiate DIC.
- Other effects of plasmin include:
- biodegredation of factors V, VII, IX and XI –> hemorrhage.
- complement activation, which results in RBC lysis –> release of ADP and membrane phospholipids (procoagulant material).
- As can be seen, the above soup results in a mess of thrombosis and hemorrhage.
- DIC is seen in a wide variety of clinical conditions and is most commonly associated with infection (esp. GN org –> endotoxin), malignancy and obstetrical complications.

Overview
The incidence of DIC is different in different diseases as it is almost always related to a life threatening condition. It depends on the cause of DIC such as cancer, infection, trauma and Obstetrical complications. The incidence of DIC is different in different diseases as it is almost always related to a life threatening condition. It depends on the cause of DIC such as cancer, infection, trauma and obstetrical complications. The prevalence of DIC depends on the clinical settings, higher versus low acquity settings. The data sometimes may underestimate the incidence of trasient or mild cases of DIC.
Epidemiology and Demographics
Incidence
- The incidence of DIC is different in different diseases as it is almost always related to a life threatening condition. It depends on the cause of DIC such as cancer, infection, trauma and Obstetrical complications[1][2]
- In 2010, the incidence of DIC was estimated to be 26.2 cases per 100,000 individuals worldwide.[3][4][5]
Prevalence
- The prevalence of DIC depends on the clinical settings, higher versus low acquity settings.
- In 2013, the prevalence of DIC was estimated to be 46.8% (292/624) [6][7][8][9]
Age
- Patients of all age groups may develop DIC.
Race
- There is no racial predilection to DIC
Gender
- DIC affects men and women equally
Developing Countries
- The prevalence of DIC depends on the clinical settings, higher versus low acquity settings.

Screening
Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Omer Kamal, M.D.[2]
Overview
There is insufficient evidence to recommend routine screening for DIC as it does not suggest any changes in mortality except in sepsis

Natural History, Complications and Prognosis
Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1] Associate Editor(s)-in-Chief: Omer Kamal, M.D.[2]
Overview
If left untreated, 40-80% patients with DIC may progress to develop organ dysfunction. Common complications of DIC include renal failure, hepatic dysfunction, acute lung injury, neurologic dysfunction and adrenal failure. Low levels of antithrombin at the onset if shock may predict an unfavorable prognosis.
