Treatment of DIC is centered around treating the underlying condition. Transfusions of platelets or fresh frozen plasma can be considered in cases of significant bleeding, or those with a planned invasive procedure. The target goal of such transfusion depends on the clinical situation. Cryoprecipitate can be considered in those with a low fibrinogen level.

Treatment of thrombosis with anticoagulants such as heparin is rarely used due to the risk of bleeding.

Recombinant human activated protein C was previously recommended in those with severe sepsis and DIC, but drotrecogin alfa has been shown to confer no benefit and was withdrawn from the market in 2011.

Recombinant factor VII has been proposed as a "last resort" in those with severe hemorrhage due to obstetric or other causes, but conclusions about its use are still insufficient.

The amount of fresh frozen plasma required to reverse disseminated intravascular coagulation associated with purpura fulminans may lead to complications of fluid overload and death, especially in neonates, such as transfusion-related acute lung injury. Exposure to multiple plasma donors over time increases the cumulative risk for transfusion-associated viral infection and allergic reaction to donor proteins found in fresh frozen plasma.

Allergic reactions and alloantibody formation are also potential complications, as with any protein replacement therapy.

Concomitant warfarin therapy in subjects with congenital protein C deficiency is associated with an increased risk of warfarin skin necrosis.

For people who have severe congenital protein C deficiency, protein C replacement therapies are available, which is indicated and approved for use in the United States and Europe for the prevention of purpura fulminans. Protein C replacement is often in combination with anticoagulation therapy of injectable low molecular weight heparin or oral warfarin. Before initiating warfarin therapy, a few days of therapeutic heparin may be administered to prevent warfarin skin necrosis and other progressive or recurrent thrombotic complications.

Prognosis varies depending on the underlying disorder, and the extent of the intravascular thrombosis (clotting). The prognosis for those with DIC, regardless of cause, is often grim: Between 20% and 50% of patients will die. DIC with sepsis (infection) has a significantly higher rate of death than DIC associated with trauma.

Due to the high mortality of untreated TTP, a presumptive diagnosis of TTP is made even when only microangiopathic hemolytic anemia and thrombocytopenia are seen, and therapy is started. Transfusion is contraindicated in thrombotic TTP, as it fuels the coagulopathy. Since the early 1990s, plasmapheresis has become the treatment of choice for TTP. This is an exchange transfusion involving removal of the patient's blood plasma through apheresis and replacement with donor plasma (fresh frozen plasma or cryosupernatant); the procedure must be repeated daily to eliminate the inhibitor and abate the symptoms. If apheresis is not available, fresh frozen plasma can be infused, but the volume that can be given safely is limited due to the danger of fluid overload. Plasma infusion alone is not as beneficial as plasma exchange. Corticosteroids (prednisone or prednisolone) are usually given. Rituximab, a monoclonal antibody aimed at the CD20 molecule on B lymphocytes, may be used on diagnosis; this is thought to kill the B cells and thereby reduce the production of the inhibitor. A stronger recommendation for rituximab exists where TTP does not respond to corticosteroids and plasmapheresis.

Caplacizumab is an alternative option in treating TTP as it has been shown that it induces a faster disease resolution compared with those patient who were on placebo. However, the use of caplacizumab was associated with increase bleeding tendencies in the studied subjects.

Most patients with refractory or relapsing TTP receive additional immunosuppressive therapy, e.g. vincristine, cyclophosphamide, splenectomy or a combination of the above.

Children with Upshaw-Schülman syndrome receive prophylactic plasma every two to three weeks; this maintains adequate levels of functioning ADAMTS13. Some tolerate longer intervals between plasma infusions. Additional plasma infusions may necessary for triggering events, such as surgery; alternatively, the platelet count may be monitored closely around these events with plasma being administered if the count drops.

Measurements of blood levels of lactate dehydrogenase, platelets, and schistocytes are used to monitor disease progression or remission. ADAMTS13 activity and inhibitor levels may be measured during follow-up, but in those without symptoms the use of rituximab is not recommended.

The mortality rate is around 95% for untreated cases, but the prognosis is reasonably favorable (80–90% survival) for patients with idiopathic TTP diagnosed and treated early with plasmapheresis.

Following are some complications of coagulopathies, some of them caused by their treatments:

The course of treatment and the success rate is dependent on the type of TMA. Some patients with atypical HUS and TTP have responded to plasma infusions or exchanges, a procedure which replaces proteins necessary for the complement cascade that the patient does not have; however, this is not a permanent solution or treatment, especially for patients with congenital predispositions.

Thrombotic microangiopathy (TMA) is a pathology that results in thrombosis in capillaries and arterioles, due to an endothelial injury. It may be seen in association with thrombocytopenia, anemia, purpura and renal failure.

The classic TMAs are hemolytic uremic syndrome and thrombotic thrombocytopenic purpura. Other conditions with TMA include atypical hemolytic uremic syndrome, disseminated intravascular coagulation, scleroderma renal crisis, malignant hypertension,

antiphospholipid antibody syndrome, and drug toxicities, e.g. calcineurin inhibitor toxicity.

Treatment of thrombotic thrombocytopenic purpura (TTP) is a medical emergency, since the associated hemolytic anemia and platelet activation can lead to renal failure and changes in the level of consciousness. Treatment of TTP was revolutionized in the 1980s with the application of plasmapheresis. According to the Furlan-Tsai hypothesis, this treatment works by removing antibodies against the von Willebrand factor-cleaving protease ADAMTS-13. The plasmapheresis procedure also adds active ADAMTS-13 protease proteins to the patient, restoring a normal level of von Willebrand factor multimers. Patients with persistent antibodies against ADAMTS-13 do not always manifest TTP, and these antibodies alone are not sufficient to explain how plasmapheresis treats TTP.

In medicine (hematology), bleeding diathesis (h(a)emorrhagic diathesis) is an unusual susceptibility to bleed (hemorrhage) mostly due to hypocoagulability, in turn caused by a coagulopathy (a defect in the system of coagulation). Several types are distinguished, ranging from mild to lethal. Also, bleeding diathesis can be caused by thinning of the skin or impaired wound healing.

Treatment is guided by the severity and specific cause of the disease. Treatment focuses on eliminating the underlying problem, whether that means discontinuing drugs suspected to cause it or treating underlying sepsis. Diagnosis and treatment of serious thrombocytopenia is usually directed by a hematologist. Corticosteroids may be used to increase platelet production. Lithium carbonate or folate may also be used to stimulate platelet production in the bone marrow.

The most important differential diagnosis is disseminated intravascular coagulation, which is characterized with similar features but presence of a low platelet count and microcirculatory thrombosis. Antifibrinolytic treatments are contraindicated in patients with disseminated intravascular coagulation while they are useful in the treatment of primary fibrinogenolysis.

Primary fibrinogenolysis is the pathological lysis of fibrinogen characterized with a low fibrinogen, high fibrin degradation products, prolonged prothrombin time and activated partial thromboplastin time, a normal platelet count and absence of microcirculatory thrombosis.

The effect of antibiotics in "E. coli" O157:H7 colitis is controversial. Certain antibiotics may stimulate further verotoxin production and thereby increase the risk of HUS. However, there is also tentative evidence that some antibiotics like quinolones may decrease the risk of hemolytic uremic syndrome. In the 1990s a group of pediatricians from the University of Washington used a network of 47 cooperating laboratories in Washington, Oregon, Idaho, and Wyoming to prospectively identify 73 children younger than 10 years of age who had diarrhea caused by "E. coli" O157:H7 The hemolytic–uremic syndrome developed in 5 of the 9 children given antibiotics (56 percent), and in 5 of the 62 children who were not given antibiotics (8 percent, P<0.001).

Treatment of HUS is generally supportive, with dialysis as needed. Platelet transfusion may actually worsen the outcome.

In most children with postdiarrheal HUS, there is a good chance of spontaneous resolution, so observation in a hospital is often all that is necessary, with supportive care such as hemodialysis where indicated. If a diagnosis of STEC-HUS is confirmed, plasmapheresis (plasma exchange) is contraindicated. However, plasmapheresis may be indicated when there is diagnostic uncertainty between HUS and TTP.

There are case reports of experimental treatments with eculizumab, a monoclonal antibody against CD5 that blocks part of the complement system, being used to treat congenital atypical hemolytic uremic syndrome, as well as severe shiga-toxin associated hemolytic uremic syndrome. These have shown promising results. Eculizeumab was approved by the U.S. Food and Drug Administration (FDA) on March 13, 2007 for the treatment of paroxysmal nocturnal hemoglobinuria (PNH), a rare, progressive, and sometimes life-threatening disease characterized by excessive hemolysis; and on September 23, 2011 for the treatment of atypical hemolytic uremic syndrome (aHUS) It was approved by the European Medicines Agency for the treatment of PNH on June 20, 2007, and on November 29, 2011 for the treatment of aHUS. However, of note is the exceedingly high cost of treatment, with one year of the drug costing over $500,000.

Scientists are trying to understand how useful it would be to immunize humans or cattles with vaccines.

With treatment, maternal mortality is about 1 percent, although complications such as placental abruption, acute renal failure, subcapsular liver hematoma, permanent liver damage, and retinal detachment occur in about 25% of women. Perinatal mortality (stillbirths plus death in infancy) is between 73 and 119 per 1000 babies of woman with HELLP, while up to 40% are small for gestational age. In general, however, factors such as gestational age are more important than the severity of HELLP in determining the outcome in the baby.

The only effective treatment is prompt delivery of the baby. Several medications have been investigated for the treatment of HELLP syndrome, but evidence is conflicting as to whether magnesium sulfate decreases the risk of seizures and progress to eclampsia. The disseminated intravascular coagulation is treated with fresh frozen plasma to replenish the coagulation proteins, and the anemia may require blood transfusion. In mild cases, corticosteroids and antihypertensives (labetalol, hydralazine, nifedipine) may be sufficient. Intravenous fluids are generally required. Hepatic hemorrhage can be treated with embolization, as well, if life-threatening bleeding ensues.

The University of Mississippi standard protocol for HELLP includes corticosteroids. However, a 2009 review found "no conclusive evidence" supporting corticosteroid therapy, and a 2010 systematic review by the Cochrane Collaboration also found "no clear evidence of any effect of corticosteroids on substantive clinical outcomes" either for the mothers or for the newborns,

Acute renal failure occurs in 55–70% of patients with STEC-HUS, although up to 70–85% recover renal function. Patients with aHUS generally have poor outcomes, with up to 50% progressing to ESRD or irreversible brain damage; as many as 25% die during the acute phase. However, with aggressive treatment, more than 90% of patients survive the acute phase of HUS, and only about 9% may develop ESRD. Roughly one-third of persons with HUS have abnormal kidney function many years later, and a few require long-term dialysis. Another 8% of persons with HUS have other lifelong complications, such as high blood pressure, seizures, blindness, paralysis, and the effects of having part of their colon removed. The overall mortality rate from HUS is 5–15%. Children and the elderly have a worse prognosis.

Splenic infarction can be induced for the treatment of such conditions as portal hypertension or splenic injury. It can also be used prior to splenectomy for the prevention of blood loss.

Treatment is almost always aimed to control hemorrhages, treating underlying causes, and taking preventative steps before performing invasive surgeries.

Hypoprothrombinemia can be treated with periodic infusions of purified prothrombin complexes. These are typically used as treatment methods for severe bleeding cases in order to boost clotting ability and increasing levels of vitamin K-dependent coagulation factors.

1. A known treatment for hypoprothrombinemia is menadoxime.

2. Menatetrenone was also listed as a Antihaemorrhagic vitamin.

3. 4-Amino-2-methyl-1-naphthol (Vitamin K5) is another treatment for hypoprothrombinemia.

1. Vitamin K forms are administered orally or intravenously.

4. Other concentrates include Proplex T, Konyne 80, and Bebulin VH.

Fresh Frozen Plasma infusion (FFP) is a method used for continuous bleeding episodes, every 3-5 weeks for mention.

1. Used to treat various conditions related to low blood clotting factors.

2. Administered by intravenous injection and typically at a 15-20 ml/kg/dose.

3. Can be used to treat acute bleeding.

Sometimes, underlying causes cannot be controlled or determined, so management of symptoms and bleeding conditions should be priority in treatment.

Invasive options, such as surgery or clotting factor infusions, are required if previous methods do not suffice. Surgery is to be avoided, as it causes significant bleeding in patients with hypoprothrombinemia.

Prognosis for patients varies and is dependent on severity of the condition and how early the treatment is managed.

1. With proper treatment and care, most people go on to live a normal and healthy life.

2. With more severe cases, a hematologist will need to be seen throughout the patient's life in order to deal with bleeding and continued risks.

A 28 month old girl, showed symptoms from 8 months of age and consisted of complaints of painful bruises over lower limbs, and disturbed, painful sleep at night. Family history revealed older brother also suffered similar problems and died at age of two years possibly due to bleeding - no diagnosis was confirmed. Complete blood count and blood smear was determined as normal. No abnormality in fibrinogen, liver function test, and bleeding time. However, prothrombin levels were less than 1% so patient was transfused with fresh frozen plasma (FFP). Post transfusion methods, patient is now 28 months old and living healthy life. The only treatment that is needed to date is for the painful bruises, which the patient is given FFP every 5-6 weeks.

Twelve day old boy admitted for symptoms consisting of blood stained vomiting and dark colored stool. Upon admission into hospital, patient received vitamin K and FFP transfusion. No family history of similarity in symptoms that were presented. At 40 days old, patient showed symptoms of tonic posturing and constant vomiting. CT scan revealed subdural hemorrhage, and other testing showed low hb levels of 7%, platelets at 3.5 lakhs/cu mm. PT examination was 51 seconds and aPTT at 87 seconds. Prothrombin activity levels were less than 1%. All other exams revealed no abnormalities. Treatment methods included vitamin K and FFP, as well as ventilator support and packed red blood cell transfusion (PRBC). At half a year of age, condition consisted of possible poor neurological outcome secondary to CNS bleeding. Treatment of very frequent transfusion was needed for patient.

Recent study illustrated a patient with 2 weeks of continuous bleeding, with presence of epistaxis, melena, hematuria, and pruritic rash with no previous bleeding history. Vitals were all within normal range, however, presence of ecchymoses was visible in chest, back and upper areas. Lab exams revealed prolonged prothrombin time (PT) of 34.4 and acquired partial thromboplastin time (aPTT) of 81.7, as well as elevated liver function tests. Discontinuation of atorvastatin, caused liver enzymes to go back to normal. Treatment of vitamin K, antibiotics, and fresh frozen plasma (FFP) did not have an impact on coagulopathy. Mixing of PT and aPTT was performed in order to further evaluate coagulopathy and revealed no correction. Factor activity assays were performed to determine the presence of a specific one. Testing revealed that factor II activity could not be quantified. Further studies showed that acquired factor II inhibitor was present without the lupus anticoagulant, with no clear cause associated with the condition. Aimed to control bleeding and getting rid of the inhibitor through directly treating the underlying disease or through immunosuppressive therapy. Corticosteroids and intravenous immunoglobulin improved the PT and aPTT. Did not improve bleeding conditions until treatment of transfusion with activated PCC. Treatment of inhibitor required Rituximab, which was shown to increase factor II levels to 264%. Study shows that when a patient with no history of coagulopathy presents themselves with hemorrhagic diathesis, direct testing of a factor II inhibitor should be performed initially.

Patient with KMS can be extremely ill and may need intensive care. They are at risk of bleeding complications including intracranial hemorrhage. The thrombocytopenia and coagulopathy are managed with platelet transfusions and fresh frozen plasma, although caution is needed due to the risk of fluid overload and heart failure from multiple transfusions. The possibility of disseminated intravascular coagulation, a dangerous and difficult-to-manage condition, is concerning. Anticoagulant and antiplatelet medications can be used after careful assessment of the risks and benefits.

KMS has a mortality rate of about 30%. For patients that survive the acute disease, supportive care may be required through a gradual recovery.

Furthermore, patients may need care from a dermatologist or plastic surgeon for residual cosmetic lesions. On long-term followup, most patients have skin discoloration and/or mild disfiguration from the dormant tumor.

There are too few cases of fibrinogen storage disease to establish optimal treatments for the liver diseases. Management of the disorder has been based on general recommendations for patients with liver disease, particularly Alpha 1 antitrypsin deficiency-associated liver disease. In the latter disease, autophagy, the pathway that cells use to dispose of dysfunctional or excessively stored components including proteins, has been targeted using autophagy-enhancing drugs, e.g. carbamazepine, vitamin E, and ursodeoxycholic acid. These drugs have been tested in individual patients with fibrin storage disease with some success in reducing evidence of liver injure, i.e. reduction in blood liver enzyme levels. These and other autophagy-enhancing drugs are suggested to be further studied in fibrinogen storage disease.

Recommended treatment of asymptomatic congenital hypofibrinogenemia depends in part on the expectations of developing bleeding and/or thrombotic complications as indicated by the personal history of the afflicted individual and family members. Where possible, determination of the exact mutation causing the disorder and the propensity of this mutation type to develop these complications may be helpful. Individuals with fibrinogen levels >1.0 gram/liter typically do not develop bleeding or thrombosis episodes. Individuals with fibrinogen levels of 0.5-1.0 grams/liter require fibrinogen supplementation preferably with a plasma-derived fibrinogen concentrate to maintain fibrinogen levels of >1 gram/liter prior to major surgery. Individuals with fibrinogen levels of 1 to 2 gram/liter at the end of pregnancy and during the postpartum period; b) > 1 gram/liter prior to major surgery; c) > 0.5 to 1 gram/liter during the first two trimesters of pregnancy; and d) >0.5 gram/liter prior to minor surgery. Tranexamic acid may be used in place of fibrinogen supplementation as prophylactic treatment prior to minor surgery and to treat minor bleeding episodes.
