Anemia or anaemia (British English) is a blood disorder in which the blood has a reduced ability to carry oxygen.This can be due to a lower than normal number of red blood cells, a reduction in the amount of hemoglobin available for oxygen transport, or abnormalities in hemoglobin that impair its function.
A breakthrough was made in 1948 with the discovery of the LE cell (the lupus erythematosus cell—a misnomer, as it occurs with other diseases as well). Discovered by a team of researchers at the Mayo Clinic, they discovered that the white blood cells contained the nucleus of another cell that was pushing against the white's cell proper nucleus.
Defects of red blood cell membrane production (as in hereditary spherocytosis and hereditary elliptocytosis). [2] Defects in hemoglobin production (as in thalassemia, sickle-cell disease and congenital dyserythropoietic anemia). [2] Defective red cell metabolism (as in glucose-6-phosphate dehydrogenase deficiency and pyruvate kinase deficiency ...
Spur cell hemolytic anemia is a form of hemolytic anemia that results when free cholesterol binds to the red blood cell's membrane increasing its surface area, causing later deformities such as rough or thorny projections on the erythrocyte named acanthocytes. This condition is caused by the deceased liver's decreased ability to esterificate ...
It is seen in systemic lupus erythematosus, where immune complexes aggregate with platelets, forming intravascular thrombi. Microangiopathic hemolytic anemia is also seen in cancer. [1] Microangiopathic hemolytic anemia may be suspected based on routine medical laboratory tests such as a CBC (complete blood cell count).
Lupus erythematosus is a collection of autoimmune diseases in which the human immune system becomes hyperactive and attacks healthy tissues. [1] Symptoms of these diseases can affect many different body systems, including joints, skin, kidneys, blood cells, heart, and lungs. The most common and most severe form is systemic lupus erythematosus.
Autoimmune hemolytic anemia (AIHA) is an autoimmune disorder which occurs when antibodies directed against the person's own red blood cells (RBCs) cause them to burst , leading to an insufficient number of oxygen-carrying red blood cells in circulation . The lifetime of the RBCs is reduced from the normal 100–120 days to just a few days in ...
The production of red blood cells (or erythropoeisis) in the body is regulated by erythropoietin, which is a protein produced by the kidneys in response to poor oxygen delivery. [14] As a result, more erythropoeitin is produced to encourage red blood cell production and increase oxygen-carrying capacity.
