Systemic sclerosis (SSc) involves fibrosis and immune activation. This review highlights how oxidative stress contributes to SSc, focusing on biomarkers linked to its key pathological features.
Area of Science:
- Rheumatology and Immunology
- Pathophysiology of Connective Tissue Diseases
Background:
- Systemic sclerosis (SSc) is a rare, severe autoimmune disease causing fibrosis in skin, muscles, and organs.
- SSc presents as limited cutaneous (lc-SSc) or diffuse cutaneous (dc-SSc) forms, with obscure etiology and unpredictable outcomes.
- Vascular injury and immune system activation are key SSc manifestations.
Purpose of the Study:
- To review and analyze recent findings on the role of oxidative stress in SSc pathogenesis.
- To summarize biomarkers that link reactive oxidizing species (ROS) to SSc pathology.
Main Methods:
- Literature review of recent studies on oxidative stress and SSc.
- Analysis of biomarkers associated with ROS and SSc hallmarks.
Main Results:
- Evidence suggests reactive oxidizing species (ROS) are significantly involved in SSc pathogenesis.
- Specific biomarkers demonstrate a link between oxidative stress and SSc's vascular and fibrotic features.
- The precise role of oxidative stress in vascular injury and fibrosis requires further clarification.
Conclusions:
- Oxidative stress is a key factor in the pathogenesis of Systemic Sclerosis.
- Biomarkers are emerging to confirm the link between ROS and SSc pathology.
- Further research is needed to fully elucidate the role of oxidative stress in SSc.
