Summary
Leukocyte agglomeration (LA) indicates leukocyte activation in polycythaemia vera patients. This activation, linked to myelopoiesis, can serve as a diagnostic marker for the disease.
Area of Science:
- Hematology
- Immunology
Context:
- Polycythaemia vera is a myeloproliferative neoplasm.
- Leukocyte activation is a potential indicator of disease activity.
Purpose:
- To investigate leukocyte activation in polycythaemia vera patients.
- To identify markers for polycythaemia vera diagnosis.
Summary:
- Leukocyte agglomeration (LA) was observed in all 10 polycythaemia vera patients, indicating leukocyte activation.
- LA normalized during remission.
- Plasma exchange trials revealed humoral factors, resistant to heat inactivation, cause this activation, suggesting a link to myelopoiesis.
Impact:
- Leukocyte activation, specifically LA, can be a diagnostic criterion for polycythaemia vera.
- Understanding these humoral factors may lead to new therapeutic targets.
