Summary

Systemic sclerosis (SSc) is an autoimmune disease causing fibrosis and vascular issues. Its severity, linked to fibrosis extent, impacts mortality and morbidity.

Area of Science:

  • Immunology
  • Pathology
  • Vascular Biology

Background:

  • Systemic sclerosis (SSc), also known as scleroderma, is a complex autoimmune disorder.
  • It is characterized by progressive fibrosis of the skin and internal organs.
  • Key features include microvascular damage and immune system abnormalities.

Purpose of the Study:

  • To summarize the key pathological and clinical features of Systemic Sclerosis.
  • To highlight the role of fibrosis and microvascular alterations in SSc pathogenesis.
  • To underscore the heterogeneity and severity of the disease.

Main Methods:

  • Review of existing literature on Systemic Sclerosis.
  • Analysis of clinical presentations and pathological hallmarks.
  • Examination of the interplay between vascular, fibrotic, and immunological factors.

Main Results:

  • SSc presents heterogeneously, from limited skin involvement (LcSSc) to diffuse disease (DcSSc).
  • Fibrosis and microvascular damage are central to SSc pathology.
  • Disease severity, mortality, and morbidity correlate with the extent of fibrotic and vascular changes.

Conclusions:

  • The pathogenesis of SSc involves intricate interactions between blood vessels, fibroblasts, and immune cells.
  • Understanding these interactions is crucial for managing SSc.
  • Fibrosis and microvascular disease are critical determinants of SSc outcomes.
