Hemoglobinopathy variants include sickle-cell disease. [38] Hemolytic anemia: D55-D59: 5534: Hemolytic anemia (also known as haemolytic anaemia) is an anemia due to hemolysis, the abnormal breakdown of red blood cells. A number of different mediating factors can cause this condition; either from within the blood cell itself (intrinsic factors ...
Until now, the only known cure for sickle cell disease was a bone marrow transplant from a donor, which carries the risk of rejection by the immune system, in addition to the difficult process of ...
However, people with co-morbidities such as anemia, cardiovascular disease, lung disease, sepsis, or who have abnormal hemoglobin species (e.g. carboxyhemoglobin, sulfhemoglobinemia or sickle hemoglobin) may experience moderate to severe symptoms at much lower levels (as low as 5–8%).
Pfizer bought Oxbryta, also known as voxelotor, as part of its $5.4 billion buyout of Global Blood Therapeutics in 2022. Pfizer is also discontinuing all studies and access programs related to the ...
