Hemolytic anemia is a type of condition that results from the premature destruction of red blood cells. In Protheragen's ongoing efforts to advance the treatment of hemolytic anemia, we are working to develop innovative therapies to improve its effective management. We have tailored solutions and strategically designed services to surpass your expectations.
Hemolytic anemia is an ensemble of disorders having in common the earlier than normal destruction of red blood cells (RBCs) resulting in reduced erythrocyte life expectancy, with an insufficient bone marrow compensation. Hemolytic anemia can be subdivided into two broad types: intrinsic (hereditary) and extrinsic (environmental), which have different causes, clinical features, and treatment options.
Classification | Types | Disease Examples (Causes) |
---|---|---|
Intrinsic Hemolytic Anemias | Membrane Disorders |
|
Enzyme Deficiencies |
|
|
Hemoglobinopathies |
|
|
Extrinsic Hemolytic Anemias | Immune-Mediated HA |
|
Non-Immune |
|
The pathogenesis of hemolytic anemia includes either an internal defect of a red blood cell (RBC) or an external destructive factor responsible for the premature destruction of erythrocytes. Intrinsic causes include genetic mutations affecting erythrocyte membrane proteins, metabolic enzymes, or hemoglobin structure, which can impair the integrity and lifespan of erythrocytes. The external factors include the immune system's destruction of the cells, the physical and mechanical harm to the erythrocytes, or infections that injure the erythrocytes directly.
