Autoimmune markers like centromere, Scl-70, and nucleolar antibodies are valuable for diagnosing scleroderma (SSc). These antibodies, found in two-thirds of SSc patients, show high specificity for the disease.

Area of Science:

  • Immunology
  • Rheumatology

Context:

  • Scleroderma (SSc) diagnosis relies on identifying specific autoantibodies.
  • Routine testing includes centromere, Scl-70, and nucleolar antibodies.

Purpose:

  • To evaluate the clinical utility of centromere, Scl-70, and nucleolar antibodies in scleroderma diagnosis.
  • To assess the prevalence and specificity of these antibodies in patients with SSc and other connective tissue diseases.

Summary:

  • 1293 sera from 497 patients were tested for centromere, Scl-70, and nucleolar antibodies.
  • These antibodies were present in 32%, 15%, and 15% of SSc patients, respectively.
  • One of these antibodies was detected in two-thirds of SSc patients with over 95% specificity for SSc.

Impact:

  • Centromere antibody is more common in limited SSc.
  • Scl-70 antibody is predominantly found in extensive SSc, particularly with trunk skin involvement.
  • Antibody prevalence correlates with specific SSc manifestations like pulmonary, calcinosis, esophageal, and telangiectasia.
