    Leukaemia and malignant lymphoma show reduced NBT reduction and phagocytosis. Acute stages of these cancers, unlike chronic myeloid leukaemia, exhibit further decreases in these immune parameters.

    Area of Science:

    • Immunology
    • Hematology
    • Oncology

    Background:

    • The NBT (Nitroblue tetrazolium) reduction test and phagocytosis indices are key indicators of neutrophil function.
    • Neutrophil dysfunction is implicated in various hematological malignancies.
    • Understanding immune parameter changes in leukaemia and lymphoma is crucial for prognosis.

    Purpose of the Study:

    • To evaluate changes in spontaneous NBT reduction and phagocytosis in patients with leukaemia and malignant lymphoma.
    • To compare these immune parameters between different types and stages of these cancers.

    Main Methods:

    • Assessment of spontaneous NBT reduction.
    • Measurement of phagocytosis indices.
    • Comparison of results in patients with leukaemia (acute and chronic myeloid), malignant lymphoma (including plasmocytoma), and lymphogranulomatosis.

    Main Results:

    • A moderate, statistically significant decrease in NBT reduction and phagocytosis was observed in leukaemia and malignant lymphoma.
    • Acute stages of acute leukaemia and lymphogranulomatosis showed further diminished NBT reduction and phagocytosis.
    • Chronic myeloid leukaemia did not exhibit these further diminutions during its acute phase.

    Conclusions:

    • Leukaemia and malignant lymphoma are associated with impaired neutrophil function, indicated by reduced NBT reduction and phagocytosis.
    • The severity of this impairment may correlate with the acute phase of certain leukaemias and lymphomas.
    • Chronic myeloid leukaemia may present a different pattern of immune response compared to other hematological malignancies.
