  2. Sickle cell disease - Wikipedia

    en.wikipedia.org/wiki/Sickle_cell_disease

    Sickle cell disease ( SCD ), also simply called sickle cell, is a group of hemoglobin-related blood disorders typically inherited. [2] The most common type is known as sickle cell anemia. [2] It results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [2] This leads to a rigid, sickle -like shape under ...

  3. Sickle cell trait - Wikipedia

    en.wikipedia.org/wiki/Sickle_cell_trait

    Sickle cell trait describes a condition in which a person has one abnormal allele of the hemoglobin beta gene (is heterozygous ), but does not display the severe symptoms of sickle cell disease that occur in a person who has two copies of that allele (is homozygous ). Those who are heterozygous for the sickle cell allele produce both normal and ...

    Neuropathic pain, hyperalgesia, osteomyelitis. A vaso-occlusive crisis is a common painful complication of sickle cell anemia in adolescents and adults. [1] [2] It is a form of sickle cell crisis. Sickle cell anemia – most common in those of African, Hispanic, and Mediterranean origin – leads to sickle cell crisis when the circulation of ...

    en.wikipedia.org/wiki/Acute_chest_syndrome

    Acute chest syndrome. The acute chest syndrome is a vaso-occlusive crisis of the pulmonary vasculature commonly seen in people with sickle cell anemia. This condition commonly manifests with a new opacification of the lung (s) on a chest x-ray. [1]

    Other names. Sickle cell-β thalassemia. Specialty. Hematology. Sickle cell-beta thalassemia is an inherited blood disorder. The disease may range in severity from being relatively benign and like sickle cell trait to being similar to sickle cell disease. [1] [2]

  7. Mendelian traits in humans - Wikipedia

    en.wikipedia.org/wiki/Mendelian_traits_in_humans

    Mendelian traits in humans. A 50/50 chance of inheritance. Sickle-cell disease is inherited in the autosomal recessive pattern. When both parents have sickle-cell trait (carrier), a child has a 25% chance of sickle-cell disease (red icon), 25% do not carry any sickle-cell alleles (blue icon), and 50% have the heterozygous (carrier) condition. [1]

  8. Autosplenectomy - Wikipedia

    en.wikipedia.org/wiki/Autosplenectomy

    Autosplenectomy can occur in cases of sickle-cell disease where the misshapen cells block blood flow to the spleen, causing scarring and eventual atrophy of the organ. Autosplenectomy is a rare condition that is linked to certain diseases but is not a common occurrence. It is also seen in systemic lupus erythematosus (SLE).

  9. Hydroxycarbamide - Wikipedia

    en.wikipedia.org/wiki/Hydroxycarbamide

    Hydroxycarbamide. Hydroxycarbamide, also known as hydroxyurea, is a medication used in sickle-cell disease, essential thrombocythemia, chronic myelogenous leukemia, polycythemia vera, and cervical cancer. [2] [3] In sickle-cell disease it increases fetal hemoglobin and decreases the number of attacks. [2] It is taken by mouth.
