Antinuclear antibodies in multiple sclerosis

P Dore-Duffy, J O Donaldson, B L Rothman

    Archives of Neurology
    |August 1, 1982
    PubMed
    Summary

    Low levels of antinuclear antibodies (ANAs) were detected in most multiple sclerosis (MS) patients. These findings suggest altered immune reactivity in MS, with potential diagnostic implications for this neurological condition.

    Area of Science:

    • Immunology
    • Neurology
    • Autoimmunity

    Background:

    • Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system.
    • Altered immune responses are implicated in the pathogenesis of MS.
    • The role of autoantibodies in MS requires further elucidation.

    Purpose of the Study:

    • To investigate the prevalence and patterns of antinuclear antibodies (ANAs) in patients with multiple sclerosis (MS).
    • To explore potential correlations between ANA presence and MS.
    • To assess the diagnostic utility of ANAs in MS detection.

    Main Methods:

    • Indirect immunofluorescence assay was employed to detect ANAs in patient and control sera.
    • Human epithelial (HEp-2) cells served as the cellular substrate for antibody detection.
    • ANA titers and fluorescence patterns were analyzed and compared between groups.

    Main Results:

    • Antinuclear antibodies (ANAs) were detected in 81% of MS patients compared to 20% of healthy controls.
    • Higher ANA titers (8-32) were observed in MS patients versus controls (rarely >8).
    • Common fluorescence patterns included diffuse, fine speckled, and diffuse with fine-speckled nuclear fluorescence.

    Conclusions:

    • The study identified a higher prevalence of ANAs in multiple sclerosis (MS) patients, suggesting altered immune reactivity.
    • These findings support the hypothesis of a heterogeneous antibody response in MS.
    • ANA detection may serve as a potential biomarker in MS research.
