Summary

Skin sclerosis extent and clinicoserological markers significantly impact systemic sclerosis (SSc) diagnosis, severity, and prognosis. Diffuse SSc shows the poorest survival, while specific antibodies aid in classifying SSc subtypes.

Area of Science:

  • Rheumatology
  • Immunology
  • Dermatology

Background:

  • Systemic sclerosis (SSc) is a complex autoimmune disease characterized by skin sclerosis and potential organ involvement.
  • Understanding the relationship between clinical presentation, serological markers, and disease outcomes is crucial for patient management.

Purpose of the Study:

  • To investigate the relevance of skin sclerosis extent and clinicoserological features in the diagnosis, severity, and prognosis of systemic sclerosis.
  • To analyze the association of specific autoantibodies with clinical subsets and disease manifestations.

Main Methods:

  • Retrospective analysis of 151 systemic sclerosis patients (126 female, 25 male) with a mean follow-up of 5.3 years.
  • Classification of patients into limited, intermediate, and diffuse cutaneous subsets.

  • Detection of serological markers (anticentromere, anti-Scl-70, antinucleolar antibodies) in SSc patients and controls with Raynaud's phenomenon.

    • Main Results:

    • Diffuse SSc was more frequent in males and had a shorter duration of Raynaud's phenomenon before onset.
    • Wider cutaneous involvement correlated with more severe SSc forms and poorer prognosis, especially in the diffuse subset.
    • Anticentromere antibodies were linked to limited SSc, while anti-Scl-70 antibodies were associated with diffuse/intermediate SSc and severe manifestations.

    Conclusions:

    • Skin sclerosis extent and specific autoantibodies are valuable indicators of SSc severity and prognosis.
    • The intermediate SSc subset appears distinct based on clinical features and survival rates.
    • Serological markers like anticentromere and anti-Scl-70 antibodies aid in classifying SSc subtypes and predicting disease course.
