Normal red blood cells look fully round and carry oxygen to the body. Because of a gene mutation, sickle cell anemia causes those red blood cells to break down early — taking a sickle or c-shape ...
With sickle cell disease — also called sickle cell anemia — red blood cells take on a folded or sickle shape that can clog tiny blood vessels and cause progressive organ damage and pain, and ...
Sickle cell disease (SCD), also simply called sickle cell, is a group of hemoglobin-related blood disorders that are typically inherited. [2] The most common type is known as sickle cell anemia. [2] Sickle cell anemia results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [2]
These edits in the genome of the hematopoietic stem cells are to reverse the effects of sickle cell disease. The cells are then re-administered into the patient. The hematopoietic stem cells are then able to produce red blood cells with the factors which promote proper red blood cell shape reducing the effects of sickle cell disease.
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.
The FDA is reviewing a drug that could cure sickle cell anemia. Right now bone marrow or stem cell transplants are the only FDA-approved cures. FDA advisers review sickle cell treatment that could ...
Vaso-occlusive crisis is a common and painful complication of sickle cell disease that occurs when blood circulation is obstructed by sickled red blood cells (red cells are usually round and flexible, but sometimes many red cells in a person with sickle cell anemia will become rigid and crescent-shaped due to polymerization of hemoglobin). [11]
Hydroxycarbamide, also known as hydroxyurea, is an antimetabolite medication used in sickle-cell disease, essential thrombocythemia, chronic myelogenous leukemia, polycythemia vera, and cervical cancer. [4] [5] In sickle-cell disease it increases fetal hemoglobin and decreases the number of attacks. [4] It is taken by mouth. [4]
