[Immunological features in ankylosing spondylitis (author's transl)].

E Prohaska, J Neumüller, G Partsch

    Wiener Klinische Wochenschrift
    |March 17, 1978
    PubMed
    Summary

    Antinuclear antibodies (ANA) were found in 20% of ankylosing spondylitis patients, often with low to moderate disease activity. This suggests ANA may be a potential biomarker in some ankylosing spondylitis cases.

    Area of Science:

    • Immunology
    • Rheumatology
    • Autoimmunity

    Context:

    • Ankylosing spondylitis (AS) is a chronic inflammatory disease primarily affecting the axial skeleton.
    • The role of autoantibodies in the pathogenesis of AS is not fully understood.
    • Previous research has yielded inconsistent findings regarding autoantibody prevalence in AS.

    Purpose:

    • To investigate the prevalence of specific autoantibodies, including antinuclear antibodies (ANA), anti-DNA antibodies, rheumatoid factor, and antistreptolysin, in patients with varying stages of ankylosing spondylitis.
    • To explore potential correlations between autoantibody presence and disease activity in AS.

    Summary:

    • Sera from 50 ankylosing spondylitis patients were analyzed for autoantibodies using immunofluorescent techniques and other assays.

  • Antinuclear antibodies (ANA) were detected in 10 patients (20%), with one case also positive for anti-DNA antibodies.
  • The disease activity in ANA-positive patients was generally low to moderate.

    • Impact:

    • This study identifies a potential association between ANA and ankylosing spondylitis, suggesting ANA may serve as a biomarker in a subset of patients.
    • The findings contribute to a better understanding of the immunological aspects of ankylosing spondylitis.
    • Further research is warranted to elucidate the specific role and clinical significance of ANA in AS pathogenesis and progression.
