Hemolytic anemia accounts for 5% of all existing anemias. [2] It has numerous possible consequences, ranging from general symptoms to life-threatening systemic effects. [2] The general classification of hemolytic anemia is either intrinsic or extrinsic. [3] Treatment depends on the type and cause of the hemolytic anemia. [2]
Its overall phenotype resembles a combination of autoimmune hemolytic anemia and immune thrombocytopenic purpura. [1] [4] [5] Autoimmune hemolytic anemia is a condition in which the red blood cells that normally carry oxygen are destroyed by an autoimmune process. Immune thrombocytopenic purpura is a condition in which platelets are destroyed ...
Congenital hemolytic anemia (CHA) is a diverse group of rare hereditary conditions marked by decreased life expectancy and premature removal of erythrocytes from blood flow. Defects in erythrocyte membrane proteins and red cell enzyme metabolism , as well as changes at the level of erythrocyte precursors, lead to impaired bone marrow ...
Pyruvate kinase deficiency is an inherited metabolic disorder of the enzyme pyruvate kinase which affects the survival of red blood cells. [4] [5] Both autosomal dominant and recessive inheritance have been observed with the disorder; classically, and more commonly, the inheritance is autosomal recessive.
People with G6PD deficiency are therefore at risk of hemolytic anemia in states of oxidative stress. Oxidative stress can result from infection and from chemical exposure to medication and certain foods. Broad beans, e.g., fava beans, contain high levels of vicine, divicine, convicine and isouramil, all of which create oxidants. [21]
Cells with the dysfunctional proteins are degraded in the spleen, which leads to a shortage of erythrocytes and results in hemolytic anemia. HS was first described in 1871, and is the most common cause of inherited hemolysis in populations of northern European descent, with an incidence of 1 in 5000 births.
Mild glutathione synthetase deficiency usually results in the destruction of red blood cells (hemolytic anemia). Rarely, affected people also excrete large amounts of a compound called 5-oxoproline (also called pyroglutamic acid, or pyroglutamate) in their urine (5-oxoprolinuria). This compound builds up when glutathione is not processed ...
A hemolytic state exists whenever the red cell survival time is shortened from the normal average of 120 days. Hemolytic anemia is the hemolytic state in which anemia is present, and bone marrow function is inferentially unable to compensate for the shortened lifespan of the red cell. Immune hemolytic states are those, both anemic and nonanemic ...
