Oxidative damage and antioxidative therapy in systemic sclerosis

Area of Science:

• Immunology
• Pathophysiology
• Oxidative Stress Research

Background:

• Systemic sclerosis (SSc) is an autoimmune connective tissue disease with diverse clinical presentations.
• Fibrosis of skin and organs is a hallmark, influenced by genetic and environmental factors.
• Emerging evidence highlights a significant role for oxidative stress in SSc pathogenesis and complications.

Purpose of the Study:

• To elucidate the mechanisms of oxidative stress in Systemic Sclerosis.
• To identify potential prooxidative markers for disease activity assessment.
• To explore the therapeutic potential of antioxidants in managing SSc.

Main Methods:

• Review of existing literature on oxidative stress in SSc.
• Analysis of the role of reactive oxygen species (ROS) in cellular processes.
• Evaluation of prooxidative markers in SSc pathogenesis.

Main Results:

• Reactive oxygen species (ROS) mediate oxidative processes affecting endothelial cells and fibroblasts in SSc.
• Prooxidative markers can potentially indicate disease activity and guide therapy.
• Antioxidative strategies are being investigated to counteract the prooxidant state.

Conclusions:

• Oxidative stress is a key factor in Systemic Sclerosis, influencing its fibrotic and vascular patterns.
• Identifying and targeting prooxidative markers could aid in personalized SSc treatment.
• Dietary and pharmacological antioxidants represent promising therapeutic avenues for SSc.
