Granulocyte transfusion therapy in children.

D A Maybee, A P Millan, F B Ruymann

    Southern Medical Journal
    |March 1, 1977
    PubMed
    Summary

    Granulocyte transfusions show promising results in neutropenic children with infections, improving granulocyte counts. Further randomized trials are needed to confirm efficacy against antibiotic and bone marrow remission variables.

    Area of Science:

    • Pediatric Hematology and Oncology
    • Infectious Diseases
    • Cellular Therapy

    Background:

    • Neutropenia in children increases susceptibility to severe infections.
    • Granulocyte transfusions are a potential therapeutic option for managing infections in neutropenic patients.

    Observation:

    • A prospective study evaluated 45 granulocyte transfusions in pediatric patients.
    • Continuous flow centrifugation was utilized for granulocyte collection.

    Findings:

    • Favorable responses were observed in most children (11 out of 13) with proven or presumed infections.
    • Granulocyte transfusions significantly increased absolute granulocyte counts one hour post-transfusion.
    • Post-transfusion granulocyte counts were inversely proportional to patient size.
    • Complete recovery was noted in a child with Nocardia asteroides sepsis and pneumonia.
    • Dramatic responses were seen in children with major gram-negative bacterial infections.

    Implications:

    • Granulocyte transfusions appear effective in treating infections in neutropenic children.
    • Randomized controlled trials are necessary to definitively establish the role of granulocyte transfusions, controlling for antibiotic therapy and bone marrow status.
