Interferon production in leukaemia.

M Chisholm, T Cartwright

    British Journal of Haematology
    |September 1, 1978
    PubMed
    Summary
    This summary is machine-generated.

    Leukocyte interferon production was normal in acute leukemia but often reduced in chronic leukemia, especially CLL. Circulating interferon was undetectable in all groups studied.

    Area of Science:

    • Immunology
    • Hematology
    • Oncology

    Background:

    • Leukocyte interferons play a role in immune response.
    • Interferon levels in patients with leukemia require further investigation.

    Purpose of the Study:

    • To investigate leukocyte interferon production and circulating levels in patients with acute and chronic leukemia.
    • To explore the relationship between interferon levels and disease characteristics.

    Main Methods:

    • In vitro interferon production assays in response to viral stimulation.
    • Measurement of circulating interferon levels.
    • Assessment of lymphocyte transformation to phytohemagglutinin (PHA).

    Main Results:

    • Circulating interferon was not detected in healthy subjects or leukemia patients.

  • In vitro interferon synthesis was normal in acute leukemia and enhanced in some cases.
  • Reduced interferon production was common in chronic leukemia, particularly in chronic lymphocytic leukemia (CLL), where lymphocyte transformation was also depressed.

    • Conclusions:

    • Leukocyte interferon production is frequently impaired in chronic leukemia, especially CLL.
    • No clear correlation was found between interferon levels, clinical/hematological parameters, or treatment effects.
    • The findings suggest potential roles for altered interferon function in leukemia pathogenesis.
