  2. Transfusion therapy (Sickle-cell disease) - Wikipedia

    en.wikipedia.org/wiki/Transfusion_therapy...

    Red cell alloimmunisation is common in people with sickle cell disease who receive transfusions in Europe and North America. [4] This is because there are ethnic differences in the frequencies of blood group antigens. [4] Blood donors are usually Caucasian whereas the blood transfusion recipients usually have an African or Afro-Caribbean ancestry.

  3. Sickle cell disease - Wikipedia

    en.wikipedia.org/wiki/Sickle_cell_disease

    Base-pair substitution that causes sickle cell anemia. The gene defect is a single nucleotide mutation of the β-globin gene, which results in glutamate being substituted by valine at position 6 of the β-globin chain. [62] Hemoglobin S with this mutation is referred to as HbS, as opposed to the normal adult HbA.

    en.wikipedia.org/wiki/Exchange_transfusion

    The person may need to be monitored for several days in the hospital after the transfusion, but the length of stay generally depends on the condition for which the exchange transfusion was performed. Sickle Cell Disease patients may be exchanged in an outpatient setting and can be sent home the very same day. [13]

  5. Beta thalassemia - Wikipedia

    en.wikipedia.org/wiki/Beta_thalassemia

    Hematopoietic stem cell transplantation (HSCT) is a potentially curative treatment for both alpha and beta thalassemia. It involves replacing the dysfunctional stem cells in the bone marrow with healthy cells from a well-matched donor.

  6. Prenatal testing - Wikipedia

    en.wikipedia.org/wiki/Prenatal_testing

    There are three purposes of prenatal diagnosis: (1) to enable timely medical or surgical treatment of a condition before or after birth, (2) to give the parents the chance to abort a fetus with the diagnosed condition, and (3) to give parents the chance to prepare psychologically, socially, financially, and medically for a baby with a health problem or disability, or for the likelihood of a ...

  7. Hemoglobin C - Wikipedia

    en.wikipedia.org/wiki/Hemoglobin_C

    HbC can combine with other abnormal hemoglobins and cause serious hemoglobinopathies. Individuals with sickle cell–hemoglobin C (HbSC), have inherited the gene for sickle cell disease (HbS) from one parent and the gene for hemoglobin C disease (HbC) from the other parent. Since HbC does not polymerize as readily as HbS, there is less sickling ...

  8. Glucose-6-phosphate dehydrogenase deficiency - Wikipedia

    en.wikipedia.org/wiki/Glucose-6-phosphate_de...

    Based on symptoms, blood test, genetic testing [2] Differential diagnosis: Pyruvate kinase deficiency, hereditary spherocytosis, sickle cell anemia [2] Treatment: Avoiding triggers, medications for infection, stopping offending medication, blood transfusions [3] Frequency: 400 million [1] Deaths: 33,000 (2015) [4]

  9. Hemoglobin O-Arab - Wikipedia

    en.wikipedia.org/wiki/Hemoglobin_O-Arab

    When combined with Hemoglobin S (β^6Glu → Val) it causes a severe form of Sickle cell disease known as Hemoglobin S/O-Arab. Detection of Hb O-Arab can be carried out with a blood test, identifying the carries of hemoglobinopathies, so as to inform patients their chances of producing an affected child and ensure appropriate guidance is given.
