There are several treatments available for factor VII deficiency; they all replace deficient FVII.

1. Recombinant FVIIa concentrate (rFVIIa) is a recombinant treatment that is highly effective and has no risk of fluid overload or viral disease. It may be the optimal therapy.

2. Plasma derived Factor VII concentrate (pdFVII) : This treatment is suitable for surgery but can lead to thrombosis. It is virus attenuated.

3. Prothrombin complex concentrate (PCC) containing factor VII: this treatment is suitable for surgery, but has a risk of thrombosis. It is virus attenuated.

4. Fresh frozen plasma (FFP): This is relatively inexpensive and readily available. While effective this treatment carries a risk of blood-borne viruses and fluid overload.

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.

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.

Early stage sepsis-associated purpura fulminans may be reversible with quick therapeutic intervention. Treatment is mainly removing the underlying cause and degree of clotting abnormalities and with supportive treatment (antibiotics, volume expansion, tissue oxygenation, etc.). Thus, treatment includes aggressive management of the septic state.

Purpura fulminans with disseminated intravascular coagulation should be urgently treated with fresh frozen plasma (10–20 mL/kg every 8–12 hours) and/or protein C concentrate to replace pro-coagulant and anticoagulant plasma proteins that have been depleted by the disseminated intravascular coagulation process.

Protein C in plasma in the steady state has a half life of 6- to 10-hour, therefore, patients with severe protein C deficiency and presenting with purpura fulminans can be treated acutely with an initial bolus of protein C concentrate 100 IU/kg followed by 50 IU /kg every 6 hours. A total of 1 IU/kg of protein C concentrate or 1 mL/kg of fresh frozen plasma will increase the plasma concentration of protein C by 1 IU/dL. Cases with comorbid pathological bleeding may require additional transfusions with platelet concentrate (10–15 mL/kg) or cryoprecipitate (5 mL/kg).

Established soft tissue necrosis may require surgical removal of the dead tissue, fasciotomy, amputation or reconstructive surgery.

There is no specific treatment for thrombophilia, unless it is caused by an underlying medical illness (such as nephrotic syndrome), where the treatment of the underlying disease is needed. In those with unprovoked and/or recurrent thrombosis, or those with a high-risk form of thrombophilia, the most important decision is whether to use anticoagulation medications, such as warfarin, on a long-term basis to reduce the risk of further episodes. This risk needs to weighed against the risk that the treatment will cause significant bleeding, as the reported risk of major bleeding is over 3% per year, and 11% of those with major bleeding may die as a result.

Apart from the abovementioned forms of thrombophilia, the risk of recurrence after an episode of thrombosis is determined by factors such as the extent and severity of the original thrombosis, whether it was provoked (such as by immobilization or pregnancy), the number of previous thrombotic events, male sex, the presence of an inferior vena cava filter, the presence of cancer, symptoms of post-thrombotic syndrome, and obesity. These factors tend to be more important in the decision than the presence or absence of a detectable thrombophilia.

Those with antiphospholipid syndrome may be offered long-term anticoagulation after a first unprovoked episode of thrombosis. The risk is determined by the subtype of antibody detected, by the antibody titer (amount of antibodies), whether multiple antibodies are detected, and whether it is detected repeatedly or only on a single occasion.

Women with a thrombophilia who are contemplating pregnancy or are pregnant usually require alternatives to warfarin during pregnancy, especially in the first 13 weeks, when it may produce abnormalities in the unborn child. Low molecular weight heparin (LMWH, such as enoxaparin) is generally used as an alternative. Warfarin and LMWH may safely be used in breastfeeding.

When women experience recurrent pregnancy loss secondary to thrombophilia, some studies have suggested that low molecular weight heparin reduces the risk of miscarriage. When the results of all studies are analysed together, no statistically signifiant benefit could be demonstrated.

There are several treatments available for bleeding due to factor X deficiency, however a specifi FX concentrate is not available (2009).

1. Prothrombin complex concentrate (PCC) supplies FX with a risk of thrombosis.

2. Fresh frozen plasma (FFP): This is relatively inexpensive and readily available. While effective this treatment carries a risk of blood-borne viruses and fluid overload.

3. If vitamin K levels are low, vitamin K can be supplied orally or parenterally.

Treatment of FX deficiency in amyloidosis may be more complex and involve surgery (splenectomy) and chemotherapy.

Protamine reverses the effect of unfractionated heparin, but only partially binds to and reverses LMWH. A dose of 1 mg protamine / 100 IU LMWH reverses 90% of its anti-IIa and 60% of anti-Xa activity, but the clinical effect of the residual anti-Xa activity is not known. Both anti-IIa and anti-Xa activity may return up to three hours after protamine reversal, possibly due to release of additional LMWH from depot tissues.

Often, this disease is treated by giving aspirin to inhibit platelet activation, and/or warfarin as an anticoagulant. The goal of the prophylactic treatment with warfarin is to maintain the patient's INR between 2.0 and 3.0. It is not usually done in patients who have had no thrombotic symptoms.

Anticoagulation appears to prevent miscarriage in pregnant women. In pregnancy, low molecular weight heparin and low-dose aspirin are used instead of warfarin because of warfarin's teratogenicity. Women with recurrent miscarriage are often advised to take aspirin and to start low molecular weight heparin treatment after missing a menstrual cycle. In refractory cases plasmapheresis may be used.

Anticoagulant therapy with LMWH is not usually monitored. LMWH therapy does not affect the prothrombin time (PT) or the INR, and anti-Xa levels are not reliable. It can prolong the partial thromboplastin time (APTT) in some women, but still, the APTT is not useful for monitoring.

To check for any thrombocytopenia, platelet count should be checked prior to commencing anticoagulant therapy, then seven to 10 days after commencement, and monthly thereafter. Platelet count should also be checked if unexpected bruising or bleeding occurs.

A minority of patients can be treated medically with sodium restriction, diuretics to control ascites, anticoagulants such as heparin and warfarin, and general symptomatic management. The majority of patients require further intervention. Milder forms of Budd–Chiari may be treated with surgical shunts to divert blood flow around the obstruction or the liver itself. Shunts must be placed early after diagnosis for best results. The TIPS is similar to a surgical shunt: it accomplishes the same goal but has a lower procedure-related mortality—a factor that has led to a growth in its popularity. If all the hepatic veins are blocked, the portal vein can be approached via the intrahepatic part of inferior vena cava, a procedure called DIPS (direct intrahepatic portocaval shunt). Patients with stenosis or vena caval obstruction may benefit from angioplasty. Limited studies on thrombolysis with direct infusion of urokinase and tissue plasminogen activator into the obstructed vein have shown moderate success in treating Budd–Chiari syndrome; however, it is not routinely attempted.

Liver transplantation is an effective treatment for Budd–Chiari. It is generally reserved for patients with fulminant liver failure, failure of shunts or progression of cirrhosis that reduces the life expectancy to 1 year. Long-term survival after transplantation ranges from 69–87%. The most common complications of transplant include rejection, arterial or venous thromboses and bleeding due to anticoagulation. Up to 10% of patients may have a recurrence of Budd–Chiari syndrome after the transplant.

Treatments include:

- bone marrow transplant

- ADA enzyme in PEG vehicle

Often, no treatment is required or necessary for reactive thrombocytosis. In cases of reactive thrombocytosis of more than 1,000x10/L, it may be considered to administer daily low dose aspirin (such as 65 mg) to minimize the risk of stroke or thrombosis.

However, in primary thrombocytosis, if platelet counts are over 750,000 or 1,000,000, and especially if there are other risk factors for thrombosis, treatment may be needed. Selective use of aspirin at low doses is thought to be protective. Extremely high platelet counts in primary thrombocytosis can be treated with hydroxyurea (a cytoreducing agent) or anagrelide (Agrylin).

In Jak-2 positive disorders, ruxolitinib (Jakafi) can be effective.

In terms of treatment for protein S deficiency the following are consistent with the "management" (and administration of) individuals with this condition ( it should be noted that the prognosis for "inherited" homozygotes is usually in line with a higher incidence of thrombosis for the affected individual):

On September 1990, the first gene therapy to combat this disease was performed by Dr. William French Anderson on a four-year-old girl, Ashanti DeSilva, at the National Institutes of Health, Bethesda, Maryland, U.S.A.

In April 2016 the Committee for Medicinal Products for Human Use of the European Medicines Agency endorsed and recommended for approval a stem cell gene therapy called Strimvelis, for children with ADA-SCID for whom no matching bone marrow donor is available.

Inferior vena cava filters (IVC filters) are used on the presumption that they reduce PE, although their effectiveness and safety profile are not well established. In general, they are only recommended in some high risk scenarios. The ACCP recommended them for those with a contraindication to anticoagulant treatment but not in addition to anticoagulation, unless an individual with an IVC filter but without a risk for bleeding develops acute proximal DVT. In this case, both anticoagulation and an IVC filter are suggested. NICE recommends caval filters in settings where someone with an acute proximal DVT or PE cannot receive anticoagulation, and that the filter is removed when anticoagulation can be safely started. While IVC filters themselves are associated with a long-term risk of DVT, they are not reason enough to maintain extended anticoagulation.

Thrombolysis is the administration of an enzyme (intravenous or directly into the affected vein through a catheter), which acts to enzymatically break up clots. This may reduce the risk of post-thrombotic syndrome by a third, and possibly reduce the risk of leg ulcers, but is associated with an increased risk of bleeding. The ACCP currently suggests anticoagulation rather than thrombolysis, but patients may choose thrombolysis if prevention of post-thrombotic syndrome outweighs concerns over the complexity, bleeding risk, and cost of the procedure. NICE recommends that thrombolysis is considered in those who have had symptoms for less than two weeks, are normally well, have a good life expectancy and a low risk of bleeding.

A mechanical thrombectomy device can remove venous clots, although the ACCP considers it an option only when the following conditions apply: "iliofemoral DVT, symptoms for < 7 days (criterion used in the single randomized trial), good functional status, life expectancy of ≥ 1 year, and both resources and expertise are available." Anticoagulation alone is suggested over thrombectomy.

Low-protein food is recommended for this disorder, which requires food products low in particular types of amino acids (e.g., methionine).

Anticoagulation, which prevents further coagulation, but does not act directly on existing clots, is the standard treatment for DVT. Balancing risk vs. benefit is important in determining the duration of anticoagulation, and three months is generally the standard length of treatment. In those with an annual risk of VTE in excess of 9%, as after an unprovoked episode, extended anticoagulation is a possibility. Those who finish VKA treatment after idiopathic VTE with an elevated D-dimer level show an increased risk of recurrent VTE (about 9% vs about 4% for normal results), and this result might be used in clinical decision-making. Thrombophilia test results rarely play a role in the length of treatment.

For acute cases in the leg, the ACCP recommended a parenteral anticoagulant (such as LMWH, fondaparinux, or unfractionated heparin) for at least five days and a VKA, the oral anticoagulant, the same day. LMWH and fondaparinux are suggested over unfractionated heparin, but both are retained in those with compromised kidney function, unlike unfractionated heparin. The VKA is generally taken for a minimum of three months to maintain an international normalized ratio of 2.0–3.0, with 2.5 as the target. The benefit of taking a VKA declines as the duration of treatment extends, and the risk of bleeding increases with age.

The ACCP recommended treatment for three months in those with proximal DVT provoked by surgery. A three-month course is also recommended for those with proximal DVT provoked by a transient risk factor, and three months is suggested over lengthened treatment when bleeding risk is low to moderate. Unprovoked DVT patients should have at least three months of anticoagulation and be considered for extended treatment. Those whose first VTE is an unprovoked proximal DVT are suggested for anticoagulation longer than three months unless there is a high risk of bleeding. In that case, three months is sufficient. Those with a second unprovoked VTE are recommended for extended treatment when bleeding risk is low, suggested for extended treatment when bleeding risk is moderate, and suggested for three months of anticoagulation in high-risk scenarios.

No specific cure has been discovered for homocystinuria; however, many people are treated using high doses of vitamin B (also known as pyridoxine). Slightly less than 50% respond to this treatment and need to take supplemental vitamin B for the rest of their lives. Those who do not respond require a Low-sulfur diet (especially monitoring methionine), and most will need treatment with trimethylglycine. A normal dose of folic acid supplement and occasionally adding cysteine to the diet can be helpful, as glutathione is synthesized from cysteine (so adding cysteine can be important to reduce oxidative stress).

Betaine (N,N,N-trimethylglycine) is used to reduce concentrations of homocysteine by promoting the conversion of homocysteine back to methionine, i.e., increasing flux through the re-methylation pathway independent of folate derivatives (which is mainly active in the liver and in the kidneys).The re-formed methionine is then gradually removed by incorporation into body protein. The methionine that is not converted into protein is converted to S-adenosyl-methionine which goes on to form homocysteine again. Betaine is, therefore, only effective if the quantity of methionine to be removed is small. Hence treatment includes both betaine and a diet low in methionine. In classical homocystinuria (CBS, or cystathione beta synthase deficiency), the plasma methionine level usually increases above the normal range of 30 micromoles/L and the concentrations should be monitored as potentially toxic levels (more than 400 micromoles/L) may be reached.

The long-term prognosis for APS is determined mainly by recurrent thrombosis, which may occur in up to 29% of patients, sometimes despite antithrombotic therapy.

The management of Glycogen storage disease IX requires treatment of symptoms by frequent intake of complex carbohydrates and protein to combat the low blood sugar. A nutritionist will advise on suitable diets. Liver function is regularly monitored and problems managed as they arise. However, liver problems have only been successfully treated by a transplant. Routine checks of metabolism are needed to ensure blood sugar (glucose) and ketones are managed. Regular moderate exercise is beneficial, although over-vigorous exercise is to be avoided, especially in those with enlarged livers.

In terms of treatment for individuals with Nezelof syndrome, which was first characterized in 1964, includes the following(how effective bone marrow transplant is uncertain) :

- Antimicrobial therapy

- IV immunoglobulin

- Bone marrow transplantation

- Thymus transplantation

- Thymus factors

Protein S deficiency is a disorder associated with increased risk of venous thrombosis. Protein S, a vitamin K-dependent physiological anticoagulant, acts as a nonenzymatic cofactor to activate protein C in the degradation of factor Va and factor VIIIa. Decreased (antigen) levels or impaired function of protein S leads to decreased degradation of factor Va and factor VIIIa and an increased propensity to venous thrombosis. Protein S circulates in human plasma in two forms: approximately 60 percent is bound to complement component C4b β-chain while the remaining 40 percent is free, only free protein S has activated protein C cofactor activity

Treatment of adenylosuccinate lyase deficiency can be done via epilepsy management with anticonvulsive drugs.Additionally the following options include:

- D-ribose and uridine administration

- Ketogenic diet

- S-adenosyl-l-methionine

The primary treatment method for fatty-acid metabolism disorders is dietary modification. It is essential that the blood-glucose levels remain at adequate levels to prevent the body from moving fat to the liver for energy. This involves snacking on low-fat, high-carbohydrate nutrients every 2–6 hours. However, some adults and children can sleep for 8–10 hours through the night without snacking.

Factor VII deficiency is a bleeding disorder characterized by a lack in the production of Factor VII (FVII) (proconvertin), a protein that causes blood to clot in the coagulation cascade. After a trauma factor VII initiates the process of coagulation in conjunction with tissue factor (TF/factor III) in the extrinsic pathway.

The condition may be inherited or acquired. It is the most common of the rare congenital coagulation disorders.
