    Summary

    Patients with progressive systemic sclerosis (PSS) and centromere antibodies showed increased organ involvement. This highlights the diagnostic and prognostic significance of antinuclear antibodies in PSS.

    Area of Science:

    • Immunology
    • Rheumatology
    • Dermatology

    Context:

    • Progressive systemic sclerosis (PSS) is a complex autoimmune disease.
    • Understanding autoantibody profiles is crucial for PSS diagnosis and management.
    • Previous research has identified various autoantibodies associated with PSS.

    Purpose:

    • To investigate the prevalence and clinical significance of antinuclear antibodies (ANA), including Scl-70 and centromere antibodies, in patients with PSS.
    • To characterize the target antigen of centromere antibodies in PSS patients.
    • To correlate autoantibody findings with clinical manifestations and organ involvement in PSS.

    Summary:

    • 36 patients with PSS were evaluated for ANA, Scl-70, and centromere antibodies.
    • All patients had high-titer ANA; 36% tested positive for Scl-70 and 22% for centromere antibodies.

  • Anti-centromere antibodies targeted a 19.5-kd polypeptide, with additional reactivity in some cases.
  • Patients with centromere antibodies exhibited greater heart, lung, and kidney involvement compared to those with anti-Scl-70 or other nuclear antibodies.

    • Impact:

    • This study identifies centromere antibodies as a potential biomarker for increased organ involvement in PSS.
    • Findings contribute to a better understanding of the immunopathogenesis of PSS.
    • Results may aid in risk stratification and personalized treatment strategies for PSS patients.
