Blood count changes due to mononuclear cell apheresis.

Summary

Mononuclear cell (MNC) apheresis significantly reduces red blood cell and platelet counts in healthy donors. While polymorphonuclear cells remain stable, MNC counts decrease, with a borderline significant reduction in CFU-GM counts.

Area of Science:

  • Hematology
  • Transfusion Medicine

Background:

  • Apheresis is a common procedure for collecting specific blood components.
  • Understanding the impact of apheresis on overall blood counts is crucial for donor safety and efficacy.

Purpose of the Study:

  • To quantify the changes in complete blood count (CBC) parameters and colony-forming unit-granulocyte-macrophage (CFU-GM) counts in healthy donors before and after apheresis.

Main Methods:

  • Complete blood counts and CFU-GM counts were analyzed in 41 healthy donors.
  • Measurements were taken immediately before and after mononuclear cell (MNC) apheresis.

Main Results:

  • Significant reductions were observed in red blood cell count (p<0.001) and platelet count (p<0.005).
  • Mononuclear cell counts significantly decreased (p<0.001), while polymorphonuclear cell counts showed no significant change.

  • A borderline significant reduction in CFU-GM counts was noted post-apheresis (p=0.05).

    • Conclusions:

    • MNC apheresis leads to significant losses of red blood cells, platelets, and MNCs in healthy donors.
    • The impact on CFU-GM counts warrants further investigation, though a trend towards reduction was observed.
