For patients with vWD type 1 and vWD type 2A, desmopressin is available as different preparations, recommended for use in cases of minor trauma, or in preparation for dental or minor surgical procedures. Desmopressin stimulates the release of vWF from the Weibel-Palade bodies of endothelial cells, thereby increasing the levels of vWF (as well as coagulant factor VIII) three- to five-fold. Desmopressin is also available as a preparation for intranasal administration (Stimate) and as a preparation for intravenous administration. Recently, the FDA has approved the use of Baxalta’s Vonvendi. This is the first recombinant form of vWF. The effectiveness of this treatment is different than desmopressin because it only contains vWF, not vWF with the addition of FVIII. This treatment is only recommended for use by individuals who are 18 years of age or older.

Desmopressin is contraindicated in vWD type 2b because of the risk of aggravated thrombocytopenia and thrombotic complications. Desmopressin is probably not effective in vWD type 2M and is rarely effective in vWD type 2N. It is totally ineffective in vWD type 3.

For women with heavy menstrual bleeding, estrogen-containing oral contraceptive medications are effective in reducing the frequency and duration of the menstrual periods. Estrogen and progesterone compounds available for use in the correction of menorrhagia are ethinylestradiol and levonorgestrel (Levona, Nordette, Lutera, Trivora). Administration of ethinylestradiol diminishes the secretion of luteinizing hormone and follicle-stimulating hormone from the pituitary, leading to stabilization of the endometrial surface of the uterus.

Desmopressin is a synthetic analog of the natural antidiuretic hormone vasopressin. Its overuse can lead to water retention and dilutional hyponatremia with consequent convulsion.

For patients with vWD scheduled for surgery and cases of vWD disease complicated by clinically significant hemorrhage, human-derived medium purity factor VIII concentrates, which also contain von Willebrand factors, are available for prophylaxis and treatment. Humate P, Alphanate, Wilate and Koate HP are commercially available for prophylaxis and treatment of vWD. Monoclonally purified factor VIII concentrates and recombinant factor VIII concentrates contain insignificant quantity of vWF, so are not clinically useful.

Development of alloantibodies occurs in 10-15% of patients receiving human-derived medium-purity factor VIII concentrates and the risk of allergic reactions including anaphylaxis must be considered when administering these preparations. Administration of the latter is also associated with increased risk of venous thromboembolic complications.

Blood transfusions are given as needed to correct anemia and hypotension secondary to hypovolemia. Infusion of platelet concentrates is recommended for correction of hemorrhage associated with platelet-type vWD.

The antifibrinolytic agents epsilon amino caproic acid and tranexamic acid are useful adjuncts in the management of vWD complicated by clinical hemorrhage. The use topical thrombin JMI and topical Tisseel VH are effective adjuncts for correction of hemorrhage from wounds.

Treatment is by intravenous infusion of factor IX, which has a longer half life than factor VIII and as such factor IX can be transfused less frequently. Blood transfusions may be needed, NSAIDS should be discontinued once the individual has been diagnosed with the condition. Any surgical procedure should be done "in concert" with tranexamic acid.

Fresh frozen plasma and cryoprecipitate are the mainstay of therapy for Factor XIII deficiency, but carry risk related to transfusion.

Recombinant factor XIII (rFXIII) is the only drug alternative to receiving blood transfusions, the traditional treatment for factor XIII deficiency. Novo Nordisk’s rFXIII, catridecacog, was approved by the US Food and Drug Administration in 2014. Although it is a recombinant protein, rFXIII subunit A is identical in structure and function to the A subunit of factor XIII naturally produced in the body by healthy individuals. These patients need exogenous subunit A of factor XIII since they have a mutation which prevents production of the A subunit. However, since the B-subunit is located on a separate chromosome, factor XIII deficient patients actually produce the B-subunit normally. When these two subunits interact in the plasma, the enzyme is activated and can act within the clotting cascade. rFXIII acts by inhibiting fibrinolysis factors which enzymatically cleave the fibrin matrix, leading to the ultimate formation of clots.

rFXIII is synthetically bio-engineered through a yeast expression system and administered intravenously. In clinical trials, the drug was administered once every four weeks or administered on-demand in order to treat bleeding episodes. The introduction of rFXIII as a treatment for factor XIII deficiency eliminates the risk of pathogenic infection present in plasma-based treatments. rFXIII treatment would also not be dependent on blood donations, consequently increasing availability and product quality. One of the biggest fears in developing rFXIII was that the body would mount an immune-response to the protein; however, several safety and pharmokinetics studies have reported no immunogenic response to rFXIII or associated yeast products.

In regards to the treatment of this genetic disorder, most individuals with severe haemophilia require regular supplementation with intravenous recombinant or plasma concentrate Factor VIII. The preventative treatment regime is highly variable and individually determined. In children, an easily accessible intravenous port ( portacath) may have to be inserted to minimise frequent traumatic intravenous cannulation. These devices have made prophylaxis in haemophilia much easier for families because the problems of "finding a vein" for infusion several times a week are eliminated. However, there are risks involved with their use, the most worrisome being that of infection, studies differ but some show an infection rate that is high These infections can usually be treated with intravenous antibiotics but sometimes the device must be removed, also, there are other studies that show a risk of clots forming at the tip of the catheter.Some individuals with severe haemophilia and most with moderate and mild haemophilia treat only as needed without a regular prophylactic schedule. Mild haemophiliacs often manage their condition with desmopressin, which releases stored factor VIII from blood vessel walls.

In congenital FXII deficiency treatment is not necessary. In acquired FXII deficiency the underlying problem needs to be addressed.

In December 2017, it was reported that doctors had used a new form of gene therapy to treat haemophilia A.

In terms of hemophilia C medication cyklokapron is often used for both treatment after an incident of bleeding and as a preventative measure to avoid excessive bleeding during oral surgery.

Treatment is usually not necessary, except in relation to operations, leading to many of those having the condition not being aware of it. In these cases, fresh frozen plasma or recombinant factor XI may be used, but only if necessary.

The afflicted may often suffer nosebleeds, while females can experience unusual menstrual bleeding which can be avoided by taking birth control such as: IUDs and oral or injected contraceptives to increase coagulation ability by adjusting hormones to levels similar to pregnancy.

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.

There is no treatment for MKD. But, the inflammation and the other effects can be reduced to a certain extent.

- IL-1 targeting drugs can be used to reduce the effects of the disorder. Anakinra is antagonist to IL-1 receptors. Anakinra binds the IL-1 receptor, preventing the actions of both IL-1α and IL-1β, and it has been proved to reduce the clinical and biochemical inflammation in MKD. It can effectively decreases the frequency as well as the severity of inflammatory attacks when used on a daily basis. Disadvantages with the usage of this drug are occurrence of painful injection site reaction and as the drug is discontinued in the near future the febrile attacks start. (Examined in a 12-year-old patient).

- Canakinumab is a long acting monoclonal antibody which is directed against IL-1β has shown to be effective in reducing both frequency and severity in patients suffering from mild and severe MKD in case reports and observational case series. It reduces the physiological effects but the biochemical parameter still remain elevated (Galeotti et al. demonstrated that it is more effective than anakinra –considered 6 patients suffering from MKD).

- Anti-TNF therapy might be effective in MKD, but the effect is mostly partial and therapy failure and clinical deterioration have been described frequently in patients on infliximab or etanercept. A beneficial effect of human monoclonal anti-TNFα antibody adalimumab was seen in a small number of MKD patients.

- Most MKD patients are benefited by anti-IL-1 therapy. However, anti-IL-1-resistant disease may also occur. Example. tocilizumab (a humanized monoclonal antibody against the interleukin-6 (IL-6) receptor). This drug is used when the patients are unresponsive towards Anakinra. (Shendi et al. treated a young woman in whom anakinra was ineffective with tocilizumab). It was found that it was effective in reducing the biochemical and clinical inflammation [30].Stoffels et al. observed reduction of frequency and severity of the inflammatory attacks, although after several months of treatment one of these two patients persistently showed mild inflammatory symptoms in the absence of biochemical inflammatory markers.

- A beneficial effect of hematopoietic stem cell transplantation can be used in severe mevalonate kinase deficiency conditions (Improvement of cerebral myelinisation on MRI after allogenic stem cell transplantation was observed in one girl). But, liver transplantation did not influence febrile attacks in this patient.

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.

In terms of treatment/management, bleeding events can be controlled by platelet transfusion.

Most heterozygotes, with few exceptions, do not have a bleeding diathesis. BSS presents as a bleeding disorder due to the inability of platelets to bind and aggregate at sites of vascular endothelial injury. In the event of an individual with mucosal bleeding tranexamic acid can be given.

The affected individual may need to avoid contact sports and medications such as aspirin, which can increase the possibility of bleeding. A potential complication is the possibility of the individual producing antiplatelet antibodies

The first element of treatment is usually to discontinue the offending drug, although there have been reports describing how the eruption evolved little after it had established in spite of continuing the medication. Vitamin K1 can be used to reverse the effects of warfarin, and heparin or its low molecular weight heparin (LMWH) can be used in an attempt to prevent further clotting. None of these suggested therapies have been studied in clinical trials.

Heparin and LMWH act by a different mechanism than warfarin, so these drugs can also be used to prevent clotting during the first few days of warfarin therapy and thus prevent warfarin necrosis (this is called 'bridging').

Based on the assumption that low levels of protein C are involved in the underlying mechanism, common treatments in this setting include fresh frozen plasma or pure activated protein C.

Since the clot-promoting effects of starting administration of 4-hydroxycoumarins are transitory, patients with protein C deficiency or previous warfarin necrosis can still be restarted on these drugs if appropriate measures are taken. These include gradual increase starting from low doses and supplemental administration of protein C (pure or from fresh frozen plasma).

The necrotic skin areas are treated as in other conditions, sometimes healing spontaneously with or without scarring, sometimes going on to require surgical debridement or skin grafting.

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.

The treatment of primary immunodeficiencies depends foremost on the nature of the abnormality. Somatic treatment of primarily genetic defects is in its infancy. Most treatment is therefore passive and palliative, and falls into two modalities: managing infections and boosting the immune system.

Reduction of exposure to pathogens may be recommended, and in many situations prophylactic antibiotics or antivirals may be advised.

In the case of humoral immune deficiency, immunoglobulin replacement therapy in the form of intravenous immunoglobulin (IVIG) or subcutaneous immunoglobulin (SCIG) may be available.

In cases of autoimmune disorders, immunosuppression therapies like corticosteroids may be prescribed.

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.

Those diagnosed are usually treated with taking a low dose (80–100 mg) Aspirin a day. Anticoagulants (e.g. Warfarin, Coumadin) or clopidogrel (Plavix) are often additionally prescribed following formation of a medically significant clot. Thrombelastography is more commonly being used to diagnose hypercoagulability and monitor anti-platelet therapy.

Two Dutch studies have followed hemophilia patients for a number of years. Both studies found that viral infections were common in hemophiliacs due to the frequent blood transfusions which put them at risk of getting blood borne infections such as HIV and hepatitis C. In the latest study which followed patients from 1992 to 2001, the male life expectancy was 59 years. If cases with known viral infections were excluded, the life expectancy was 72, close to that of the general population. 26% of the cases died from AIDS and 22% from hepatitis C.

Bone marrow transplant may be possible for Severe Combined Immune Deficiency and other severe immunodeficiences.

Virus-specific T-Lymphocytes (VST) therapy is used for patients who have received hematopoietic stem cell transplantation that has proven to be unsuccessful. It is a treatment that has been effective in preventing and treating viral infections after HSCT. VST therapy uses active donor T-cells that are isolated from alloreactive T-cells which have proven immunity against one or more viruses. Such donor T-cells often cause acute graft-versus-host disease (GVHD), a subject of ongoing investigation. VSTs have been produced primarily by ex-vivo cultures and by the expansion of T-lymphocytes after stimulation with viral antigens. This is carried out by using donor-derived antigen-presenting cells. These new methods have reduced culture time to 10–12 days by using specific cytokines from adult donors or virus-naive cord blood. This treatment is far quicker and with a substantially higher success rate than the 3–6 months it takes to carry out HSCT on a patient diagnosed with a primary immunodeficiency. T-lymphocyte therapies are still in the experimental stage; few are even in clinical trials, none have been FDA approved, and availability in clinical practice may be years or even a decade or more away.

Heparin enhances ATIII activity and neutralizes "activated serine protease coagulation factors." Patients with ATIII deficiency requiring anticoagulant therapy with heparin will need higher doses of heparin. ATIII binds to thrombin and then forms the thrombin-anti thrombin complex or TAT complex. This is a major natural pathway of anticoagulation. This binding of thrombin to AT is greatly enhanced in the presence of heparin. Heparin does not affect vitamin K metabolism, so giving vitamin K1 (Phytonadione) will not reverse the effects of heparin.

Heparin is used as "bridging" therapy when initiating a patient on warfarin in a hospital setting. It can be used in DVT prophylaxis and treatment, acute coronary syndromes, and ST-segment elevated MI.

Treatment consists mainly of high dose antibiotics for active infections and prophylactic antibiotics for prevention of future infections. GM-CSF therapy or bone marrow transplant might be considered for severe cases. Prognosis is difficult to predict, but patients receiving treatment are generally able to survive to adulthood.

In general, treatment for acquired partial lipodystrophy is limited to cosmetic, dietary, or medical options. Currently, no effective treatment exists to halt its progression.

Diet therapy has been shown to be of some value in the control of metabolic problems. The use of small, frequent feedings and partial substitution of medium-chain triglycerides for polyunsaturated fats appears to be beneficial.

Plastic surgery with implants of monolithic silicon rubber for correction of the deficient soft tissue of the face has been shown to be effective. False teeth may be useful in some cases for cosmetic reasons. Long-term treatment usually involves therapy for kidney and endocrine dysfunction.

Data on medications for APL are very limited. Thiazolidinediones have been used in the management of various types of lipodystrophies. They bind to peroxisome proliferator-activator receptor gamma (PPAR-gamma), which stimulates the transcription of genes responsible for growth and differentiation of adipocytes. A single report has suggested a beneficial effect from treatment with rosiglitazone on fat distribution in acquired partial lipodystrophy; however, preferential fat gain was in the lower body.

Direct drug therapy is administered according to the associated condition. Membranoproliferative glomerulonephritis and the presence of renal dysfunction largely determine the prognosis of acquired partial lipodystrophy. Standard guidelines for the management of renal disease should be followed. The course of membranoproliferative glomerulonephritis in acquired partial lipodystrophy has not been significantly altered by treatment with corticosteroids or cytotoxic medications. Recurrent bacterial infections, if severe, might be managed with prophylactic antibiotics.

Factor XII deficiency (also Hageman factor deficiency) is a deficiency in the production of factor XII (FXII), a plasma glycoprotein and clotting factor that participates in the coagulation cascade and activates factor XI. FXII appears to be not essential for blood clotting, as individuals with this condition are usually asymptomatic and form blood clots in vivo. FXII deficiency tends to be identified during presurgical laboratory screening for bleeding disorders.

The condition can be inherited or acquired.

Critics of the diagnosis complain that case evidence is spotty and lacking controlled clinical studies.
