Overview
Neutropenia may develop as a result of one of the three mechanisms: impaired granulocyte production, margination, and peripheral destruction. Genes involved in the pathogenesis of neutropenia include ELA2, HAX1, and CXCR4.
Pathophysiology
Pathogenesis
Neutropenia may develop as a result of one of the three mechanisms:[1]
1) Impaired granulocyte production
- Hematologic malignancy with bone marrow infiltration
- Myelosuppressive chemotherapy or other medications that are toxic to the bone marrow
- Nutritional deficiencies
2) Margination (process where free flowing blood cells exit circulation)
- Splenic sequestration
- Adherence to the vascular endothelium
3) Peripheral destruction
- Autoimmune hemolysis
- Drug-induced hemolysis
Genetics
Genes involved in the pathogenesis of neutropenia include ELA2, HAX1, and CXCR4.
