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

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.

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

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

Hemoglobinopathy is a kind of genetic defect that results in abnormal structure of one of the globin chains of the hemoglobin molecule. Hemoglobinopathies are inherited single-gene disorders; in most cases, they are inherited as autosomal co-dominant traits. Common hemoglobinopathies include sickle-cell disease. It is estimated that 7% of world's population (420 million) are carriers, with 60% of total and 70% pathological being in Africa. Hemoglobinopathies are most common in populations from Africa, the Mediterranean basin and Southeast Asia.

Hemoglobinopathies imply structural abnormalities in the globin proteins themselves. Thalassemias, in contrast, usually result in underproduction of normal globin proteins, often through mutations in regulatory genes. The two conditions may overlap, however, since some conditions which cause abnormalities in globin proteins (hemoglobinopathy) also affect their production (thalassemia). Thus, some hemoglobinopathies are also thalassemias, but most are not.

Either hemoglobinopathy or thalassemia, or both, may cause anemia. Some well-known hemoglobin variants such as sickle-cell anemia and congenital dyserythropoietic anemia are responsible for diseases, and are considered hemoglobinopathies. However, many hemoglobin variants do not cause pathology or anemia, and thus are often not classed as hemoglobinopathies, because they are not considered pathologies. Hemoglobin variants are a part of the normal embryonic and fetal development, but may also be pathologic mutant forms of hemoglobin in a population, caused by variations in genetics. Other variants cause no detectable pathology, and are thus considered non-pathological variants.

In general on alkaline electrophoresis in order of increasing mobility are hemoglobins A2, E=O=C, G=D=S=Lepore, F, A, K, J, Bart's, N, I, and H.

In general a sickling test (sodium bisulfite) is performed on abnormal hemoglobins migrating in the S location to see if the red cells precipitate in solution.

Congenital hemolytic anemia (or hereditary hemolytic anemia) refers to hemolytic anemia which is primarily due to congenital disorders.

Hereditary persistence of fetal hemoglobin (HPFH, BrE: "Hereditary persistence of foetal haemoglobin") is a benign condition in which significant fetal hemoglobin (hemoglobin F) production continues well into adulthood, disregarding the normal shutoff point after which only adult-type hemoglobin should be produced.

Basically classified by causative mechanism, types of congenital hemolytic anemia include:

- Genetic conditions of RBC Membrane

- Hereditary spherocytosis

- Hereditary elliptocytosis

- Genetic conditions of RBC metabolism (enzyme defects). This group is sometimes called "congenital nonspherocytic (hemolytic) anemia", which is a term for a congenital hemolytic anemia without spherocytosis, and usually excluding hemoglobin abnormalities as well, but rather encompassing defects of glycolysis in the erythrocyte.

- Glucose-6-phosphate dehydrogenase deficiency (G6PD or favism)

- Pyruvate kinase deficiency

- Aldolase A deficiency

- Hemoglobinopathies/genetic conditions of hemoglobin

- Sickle cell anemia

- Congenital dyserythropoietic anemia

- Thalassemia

In persons with sickle cell disease, high levels of fetal hemoglobin as found in a newborn or as found abnormally in persons with hereditary persistence of fetal hemoglobin, the HbF causes the sickle cell disease to be less severe. In essence the HbF inhibits polymerization of HbS. A similar mechanism occurs with persons who have sickle cell "trait". Approximately 40% of the hemoglobin is in the HbS form while the rest is in normal HbA form. The HbA form interferes with HbS polymerization.

There is no treatment that directly interferes with the disease process, although dietary restriction of calcium has been tried with limited results. For excessive areas of skin, plastic surgery may be needed. For the growth of abnormal blood vessels in the retina, laser photocoagulation and photodynamic therapy may be used; injections with triamcinolone have shown limited effect. Antiangiogenic drugs such as bevacizumab (Avastin) and ranibizumab (Lucentis) have been effective, similar to its efficacy in age-related macular degeneration. Cardiovascular disease is treated as in individuals without PXE. Some recommend avoidance of nonsteroidal anti-inflammatory drugs (NSAIDS) that increase bleeding risk, such as aspirin, and ibuprofen.

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.

Most patients recover completely within 1–2 months.

However many reported cases have lasted 18–24 months and longer.

Individuals with TEC have a median age of presentation of 18–26 months; however, the disorder may occur in infants younger than 6 months and in children as old as age 10 years.

Because of the gradual onset of the anemia, children are often healthier than expected from their low hemoglobin levels.

Pseudoxanthoma elasticum (PXE), also known as Grönblad–Strandberg syndrome, is a genetic disease that causes fragmentation and mineralization of elastic fibers in some tissues. The most common problems arise in the skin and eyes, and later in blood vessels in the form of premature atherosclerosis. PXE is caused by autosomal recessive mutations in the "ABCC6" gene on the short arm of chromosome 16 (16p13.1).

Splenic infarction is a condition in which oxygen supply to the spleen is interrupted, leading to partial or complete infarction (tissue death due to oxygen shortage) in the organ.

Splenic infarction occurs when the splenic artery or one of its branches are occluded, for example by a blood clot. Although it can occur asymptomatically, the typical symptom is severe pain in the left upper quadrant of the abdomen, sometimes radiating to the left shoulder. Fever and chills develop in some cases. It has to be differentiated from other causes of acute abdomen.

An abdominal CT scan is the most commonly used modality to confirm the diagnosis, although abdominal ultrasound can also contribute.

There is no specific treatment, except treating the underlying disorder and providing adequate pain relief. Surgical removal of the spleen (splenectomy) is only required if complications ensue; surgical removal predisposes to overwhelming post-splenectomy infections.

In one series of 59 patients, mortality amounted to 5%. Complications include a ruptured spleen, bleeding, an abscess of the spleen (for example, if the underlying cause is infective endocarditis) or pseudocyst formation. Splenectomy may be warranted for persistent pseudocysts due to the high risk of subsequent rupture.

Cardiovascular disease is the principal cause of death in the UAE, constituting 28 percent of total deaths; other major causes are accidents and injuries, malignancies, and congenital anomalies.

In 1985 the UAE established a national program to prevent transmission of acquired immune deficiency syndrome (AIDS) and to control its entry into the country. According to World Health Organization estimates, in 2002−3 fewer than 1,000 people in the UAE were living with human immunodeficiency virus (HIV)/AIDS.
