T-lymphocyte subsets modifications in multiple sclerosis: correlation with clinical disease activity.

M Prencipe, E Salerni, C D'Aurizio

    Italian Journal of Neurological Sciences
    |December 1, 1986
    PubMed
    Summary

    Multiple sclerosis patients showed a significant decrease in T8+ lymphocytes within four weeks of relapse onset. However, this T8+ cell reduction cannot reliably predict future multiple sclerosis relapses.

    Area of Science:

    • Immunology
    • Neurology
    • Hematology

    Background:

    • Multiple sclerosis (MS) is a chronic autoimmune disease affecting the central nervous system.
    • T-lymphocyte subsets play a crucial role in immune regulation and have been implicated in MS pathogenesis.
    • Understanding T-cell dynamics during MS relapses is vital for disease management.

    Purpose of the Study:

    • To investigate the serial changes in peripheral blood T-lymphocyte subsets in patients with multiple sclerosis.
    • To determine if T-lymphocyte subset alterations correlate with disease activity and relapse onset.
    • To evaluate the potential of T8+ cell counts as a predictor for MS relapses.

    Main Methods:

    • Serial peripheral blood samples were collected from 14 multiple sclerosis patients over 27 months.

  • T-lymphocyte subsets were analyzed using flow cytometry.
  • Statistical analysis was performed to compare T-cell subset counts at different time points relative to relapse events.

    • Main Results:

    • A significant decrease in T8+ cells was observed in 47.1% of samples collected within four weeks of relapse onset.
    • In contrast, only 2.1% of samples collected before relapse and 3.4% after relapse showed decreased T8+ cells.
    • T-cell subset changes appeared to correlate with multiple sclerosis disease activity.

    Conclusions:

    • Peripheral blood T8+ cell counts decrease significantly around the time of multiple sclerosis relapse.
    • Normal T8+ cell levels observed before relapses indicate that this marker is not a valid predictor of future MS events.
    • T-lymphocyte subset dynamics offer insights into MS pathogenesis but require further investigation for predictive value.
