Occasionally, the anemia is so severe that support with transfusion is required. These patients usually do not respond to erythropoietin therapy. Some cases have been reported that the anemia is reversed or heme level is improved through use of moderate to high doses of pyrodoxine (vitamin B). In severe cases of SBA, bone marrow transplant is also an option with limited information about the success rate. Some cases are listed on MedLine and various other medical sites. In the case of isoniazid-induced sideroblastic anemia, the addition of B is sufficient to correct the anemia. Desferrioxamine, a chelating agent, is used to treat iron overload from transfusions.

Therapeutic phlebotomy can be used to manage iron overload.

Multiple blood transfusions can result in iron overload. The iron overload related to thalassemia may be treated by chelation therapy with the medications deferoxamine, deferiprone, or deferasirox. These treatments have resulted in improving life expectancy in those with thalassemia major.

Deferoxamine is only effective via daily injections which makes its long-term use more difficult. It has the benefit of being inexpensive and decent long-term safety. Adverse effects are primary skin reactions around the injection site and hearing loss.

Deferasirox has the benefit of being an oral medication. Common side effects include: nausea, vomiting and diarrhea. It however is not effective in everyone and is probably not suitable in those with significant cardiac issues related to iron overload. The cost is also significant.

Deferiprone is a medication that is given by mouth. Nausea, vomiting, and diarrhea are relatively common with its use. It is available in both Europe and the United States. It appears to be the most effective agent when the heart is significantly involved.

There is no evidence from randomized controlled trial to support zinc supplementation in thalassemia.

People with severe thalassemia require medical treatment. A blood transfusion regimen was the first measure effective in prolonging life.

Although research is ongoing, at this point there is no cure for the genetic defect that causes hereditary spherocytosis. Current management focuses on interventions that limit the severity of the disease. Treatment options include:

- Splenectomy: As in non-hereditary spherocytosis, acute symptoms of anemia and hyperbilirubinemia indicate treatment with blood transfusions or exchanges and chronic symptoms of anemia and an enlarged spleen indicate dietary supplementation of folic acid and splenectomy, the surgical removal of the spleen. Splenectomy is indicated for moderate to severe cases, but not mild cases. To decrease the risk of sepsis, post-splenectomy spherocytosis patients require immunization against the influenza virus, encapsulated bacteria such as Streptococcus pneumoniae and meningococcus, and prophylactic antibiotic treatment. However, the use of prophylactic antibiotics, such as penicillin, remains controversial.

- Partial splenectomy: Since the spleen is important for protecting against encapsulated organisms, sepsis caused by encapsulated organisms is a possible complication of splenectomy. The option of partial splenectomy may be considered in the interest of preserving immune function. Research on outcomes is currently limited, but favorable.

- Surgical removal of the gallbladder may be necessary.

Usually no treatment is needed. Folic acid supplementation may help produce normal red blood cells and improve the symptoms of anemia

Most affected individuals with pyruvate kinase deficiency do not require treatment. Those individuals who are more severely affected may die in utero of anemia or may require intensive treatment. With these severe cases of pyruvate kinase deficiency in red blood cells, treatment is the only option, there is no cure. However, treatment is usually effective in reducing the severity of the symptoms.

The most common treatment is blood transfusions, especially in infants and young children. This is done if the red blood cell count has fallen to a critical level. The transplantation of bone marrow has also been conducted as a treatment option.

There is a natural way the body tries to treat this disease. It increases the erythrocyte production (reticulocytosis) because reticulocytes are immature red blood cells that still contain mitochondria and so can produce ATP via oxidative phosphorylation. Therefore, a treatment option in extremely severe cases is to perform a splenectomy. This does not stop the destruction of erythrocytes but it does help increase the amount of reticulocytes in the body since most of the hemolysis occurs when the reticulocytes are trapped in the hypoxic environment of the spleen. This reduces severe anemia and the need for blood transfusions.

Sideroblastic anemias are often described as responsive or non-responsive in terms of increased hemoglobin levels to pharmacological doses of vitamin B.

1- Congenital: 80% are responsive, though the anemia does not completely resolve.

2- Acquired clonal: 40% are responsive, but the response may be minimal.

3- Acquired reversible: 60% are responsive, but course depends on treatment of the underlying cause.

Severe refractory sideroblastic anemias requiring regular transfusions and/or that undergo leukemic transformation (5-10%) significantly reduce life expectancy.

Treatments for anemia depend on cause and severity. Vitamin supplements given orally (folic acid or vitamin B) or intramuscularly (vitamin B) will replace specific deficiencies.

In cases where oral iron has either proven ineffective, would be too slow (for example, pre-operatively) or where absorption is impeded (for example in cases of inflammation), parenteral iron can be used. The body can absorb up to 6 mg iron daily from the gastrointestinal tract. In many cases the patient has a deficit of over 1,000 mg of iron which would require several months to replace. This can be given concurrently with erythropoietin to ensure sufficient iron for increased rates of erythropoiesis.

In terms of treatment for delta-beta thalassemia one possible concern would be anemia, where, therefore, blood transfusions would be given to the affected individual (though blood transfusions might introduce complications, as well).

Stem cell transplant is another option, but the donor and the individual who will receive the bone marrow transplant must be compatible, the risks involved should be evaluated, as well

Genetic counseling may be appropriate for high-risk couples who wish to have a baby.

Experimental gene therapy exists to treat hereditary spherocytosis in lab mice; however, this treatment has not yet been tried on humans due to all of the risks involved in human gene therapy.

The goals of therapy are to control symptoms, improve quality of life, improve overall survival, and decrease progression to AML.

The IPSS scoring system can help triage patients for more aggressive treatment (i.e. bone marrow transplant) as well as help determine the best timing of this therapy. Supportive care with blood products and hematopoietic growth factors (e.g. erythropoietin) is the mainstay of therapy. The regulatory environment for the use of erythropoietins is evolving, according to a recent US Medicare National coverage determination. No comment on the use of hematopoeitic growth factors for MDS was made in that document though.

Three agents have been approved by the FDA for the treatment of MDS:

1. 5-azacytidine: 21-month median survival

2. Decitabine: Complete response rate reported as high as 43%. A phase I study has shown efficacy in AML when decitabine is combined with valproic acid.

3. Lenalidomide: Effective in reducing red blood cell transfusion requirement in patients with the chromosome 5q deletion subtype of MDS

Chemotherapy with the hypomethylating agents 5-azacytidine and decitabine has been shown to decrease blood transfusion requirements and to retard the progression of MDS to AML. Lenalidomide was approved by the FDA in December 2005 only for use in the 5q- syndrome. In the United States, treatment of MDS with lenalidomide costs about $9,200 per month.

Stem cell transplantation, particularly in younger (i.e. less than 40 years of age) and more severely affected patients, offers the potential for curative therapy. Success of bone marrow transplantation has been found to correlate with severity of MDS as determined by the IPSS score, with patients having a more favorable IPSS score tending to have a more favorable outcome with transplantation.

Iron overload can develop in MDS as a result of the RBC transfusions which are a major part of the supportive care for anemic MDS patients. Although the specific therapies patients receive may alleviate the RBC transfusion need in some cases, many MDS patients may not respond to these treatments, thus may develop iron overload from repeated RBC transfusions.

Patients requiring relatively large numbers of RBC transfusions can experience the adverse effect of chronic iron overload on their liver, heart, and endocrine functions. The resulting organ dysfunction from transfusional iron overload might be a contributor to increased illness and death in early-stage MDS.

For patients requiring many RBC transfusions, serum ferritin levels, number of RBC transfusions received, and associated organ dysfunction (heart, liver, and pancreas) should be monitored to determine iron levels. Monitoring serum ferritin may also be useful, aiming to decrease ferritin levels to .

Currently, two iron chelators are available in the US, deferoxamine for intravenous use and deferasirox for oral use. These options now provide potentially useful drugs for treating this iron overload problem. A third chelating agent is available in Europe, deferiprone for oral use, but not available in the US.

Clinical trials in the MDS are ongoing with iron chelating agents to address the question of whether iron chelation alters the natural history of patients with MDS who are transfusion dependent. Reversal of some of the consequences of iron overload in MDS by iron chelation therapy have been shown.

Both the MDS Foundation and the National Comprehensive Cancer Network MDS Guidelines Panel have recommended that chelation therapy be considered to decrease iron overload in selected MDS patients. Evidence also suggests a potential value exists to iron chelation in patients who will undergo a stem cell transplant.

Although deferasirox is generally well tolerated (other than episodes of gastrointestinal distress and kidney dysfunction in some patients), recently a safety warning by the FDA and Novartis was added to deferasirox treatment guidelines. Following postmarketing use of deferasirox, rare cases of acute kidney failure or liver failure occurred, some resulting in death. Due to this, patients should be closely monitored on deferasirox therapy prior to the start of therapy and regularly thereafter.

There are a multiple ways to treat Gunther's diseases, but one of the most crucial things that a person with this disease can do is limit themselves from sun exposure or eliminate sun exposure altogether. There are some sunscreens that have undesirable effects such as tropical sunscreens, but other sunscreens that have zinc oxide and titanium dioxide in them are shown to provide protection due to those light-reflective agents. To block the ultraviolet and visible light wavelengths and get the protection that patients with Gunther's disease require, physical barriers are needed. It is also advised that patients wear protective clothing to block the sun from their skin. Plastic films can be attached to car windows and homes to filter out some of the wavelengths that could cause harm to someone's skin suffering with this disease. Incandescent bulbs replace the normal fluorescent lamps. These bulbs release less light, which prevents the "porphyrin-exciting" wavelengths that fluorescent lights emit.

Other less beneficial treatments have been used to help treat Gunther's disease. These include oral beta-carotene and other treatments such as activated charcoal and cholestyramine, which are used to interrupt and stop the porphyrins from being reabsorbed in the body. The reason that these oral treatments are unreasonable is because they require an extremely large dose of medicine and therefore are not beneficial.

Erythrocyte transfusions have been shown to be a successful measure in decreasing the appearance of the disease by trying to lower the erythropoiesis and circulating porphyrin levels. Unfortunately, having chronic erythrocyte transfusions, it can be extremely harmful to the body and can cause severe complications.

To help with dry eye symptoms and visual function, using topical lubrication can be used.

A more invasive way to help treat Gunther's disease would be to have surgery. There have been numerous studies that have stated that bone marrow transplantation is successful. This is a recently new development for Gunther's disease so the long-term effects are still unresourced. If a patient has a life-threatening infectious complication then bone marrow transplantation is no longer relevant for them.

There are also reports that stem cell transplantation is successful in a limited number of participants

In terms of treatment of atransferrinemia, iron supplements (oral iron therapy) are the preferred choice, one finds that RBC transfusions are very infrequently needed.

Regular administration of exogenous granulocyte colony-stimulating factor (filgrastim) clinically improves neutrophil counts and immune function and is the mainstay of therapy, although this may increase risk for myelofibrosis and acute myeloid leukemia in the long term.

Over 90% of SCN responds to treatment with granulocyte colony-stimulating factor (filgrastim), which has significantly improved survival.

Delta-beta thalassemia is a form of thalassemia, and is autosomal recessive in terms of heredity. It is associated with "hemoglobin subunit delta"

Microcytic anaemia is any of several types of anaemia characterized by small red blood cells (called microcytes). The normal mean corpuscular volume (abbreviated to MCV on full blood count results) is 80-100 fL, with smaller cells (100 fL) as macrocytic (the latter occur in macrocytic anemia).The MCV is the average red blood cell size.

In microcytic anaemia, the red blood cells (erythrocytes) are usually also hypochromic, meaning that the red blood cells appear paler than usual. This is reflected by a lower-than-normal mean corpuscular hemoglobin concentration (MCHC), a measure representing the amount of hemoglobin per unit volume of fluid inside the cell; normally about 320-360 g/L or 32-36 g/dL. Typically, therefore, anemia of this category is described as "microcytic, hypochromic anaemia".

Initial treatment is with glucocorticoid corticosteroids or intravenous immunoglobulin, a procedure that is also used in ITP cases. In children, good response to a short steroid course is achieved in approximately 80 percent of cases. Although the majority of cases initially respond well to treatment, relapses are not uncommon and immunosuppressive drugs (e.g. ciclosporin, mycophenolate mofetil, vincristine and danazol) are subsequently used, or combinations of these.

The off-label use of rituximab (trade name Rituxan) has produced some good results in acute and refractory cases, although further relapse may occur within a year. Splenectomy is effective in some cases, but relapses are not uncommon.

The only prospect for a permanent cure is the high-risk option of an allogeneic hematopoietic stem cell transplantation (SCT).

Typical causes of microcytic anemia include:

- Childhood

- Iron deficiency anemia, by far the most common cause of anemia in general and of microcytic anemia in particular

- Thalassemia

- Adulthood

- Iron deficiency anemia

- Sideroblastic anemia, In congenital sideroblastic anemia the MCV (mean corpuscular volume) is either low or normal. In contrast, the MCV is usually high in the much more common acquired sideroblastic anemia.

- Anemia of chronic disease, although this more typically causes normochromic, normocytic anemia. Microcytic anemia has been discussed by Weng et al.

- Lead poisoning

- Vitamin B (pyridoxine) deficiency

Other causes that are typically thought of as causing normocytic anemia or macrocytic anemia must also be considered, and the presence of two or more causes of anemia can distort the typical picture.

There are five main causes of microcytic anemia forming the acronym TAILS. Thalassemia, Anemia of chronic disease, Iron deficiency, Lead poisoning and Congenital sideroblastic anemia. Only the first three are common in most parts of the world. In theory, these three can be differentiated by their red blood cell (RBC) morphologies. Anemia of chronic disease shows unremarkable RBCs, iron deficiency shows anisocytosis, anisochromia and elliptocytosis, and thalessemias demonstrate target cells and coarse basophilic stippling. In practice though elliptocytes and anisocytosis are often seen in thalessemia and target cells occasionally in iron deficiency. All three may show unremarkable RBC morphology. Coarse basophlic stippling is one reliable morphologic finding of thalessemia which does not appear in iron deficiency or anemia of chronic disease. The patient should be in an ethnically at risk group and the diagnosis is not confirmed without a confirmatory method such as hemoglobin HPLC, H body staining, molecular testing or another reliable method. Course basophlic stippling occurs in other cases as seen in Table 1

Genetic testing for the presence of mutations in protein molecules is considered to be a confirmatory testing technique. It is important to know the risks regarding the transmission and dangers of HPP.

The serum iron and total iron-binding capacity (transferrin) are helpful but not diagnostic; it is quiet possible to have co-existing ineffective iron utilisation and iron deficiency, as determined by bone marrow iron status, e.g. in rheumatoid arthritis.

Normocytic anemia is a type of anemia and is a common issue that occurs for men and women typically over 85 years old. Its prevalence increases with age, reaching 44 percent in men older than 85 years.

The issue is thought of as representing any of the following:

- a decreased production of normal-sized red blood cells (e.g., anemia of chronic disease, aplastic anemia);

- an increased production of HbS as seen in sickle cell disease (not sickle cell trait);

- an increased destruction or loss of red blood cells (e.g., hemolysis, posthemorrhagic anemia);

- an uncompensated increase in plasma volume (e.g., pregnancy, fluid overload);

- a B2 (riboflavin) deficiency

- a B6 (pyridoxine) deficiency

- or a mixture of conditions producing microcytic and macrocytic anemia.

Blood loss, suppressed production of RBCs or hemolysis represent most cases of normocytic anemia. In blood loss, morphologic findings are generally unremarkable except after 12 to 24 hrs where polychromasia appears. For reduced production of RBCs, like with low erythropoietin, the RBC morphology is unremarkable. Patients with disordered RBC production, e.g. myelodysplastic syndrome, may have a dual population of elliptocytes, teardrop cells, or other poikilocytes as well as a nucleated RBCs. Hemolysis will often demonstrate poikilocytes specific to a cause or mechanism. E.g. Bite cells and/or blistor cells for oxidative hemolysis, Acanthocytes for pyruvate kinase deficiency or McLeod phenotype, Sickle cells for sickle cell anemia, Spherocytes for immune-mediated hemolysis or hereditary spherocytosis, Elliptocytosis for iron deficiency or hereditary elliptocytosis and schistocytes for intravascular hemolysis. Many hemolytic anemias show multiple poikilocytes such as G6PD deficiency which may show blister and bites cells as well as shistocytes. Neonatal hemolysis may not follow the classic patterns as in adults
