Rheumatoid Arthritis and Oxidative Stress

Area of Science:

• Immunology
• Biochemistry
• Environmental Health

Background:

• Rheumatoid arthritis (RA) is a prevalent autoimmune disease affecting ~1% of the global population.
• Oxidative stress (OS) is increasingly recognized for its role in RA pathogenesis, causing cellular damage and synovial inflammation.
• Factors like metabolism, pollution, diet, and microbiota imbalances contribute to the overproduction of reactive oxygen species (ROS) in RA.

Purpose of the Study:

• To review a decade of research on how known RA risk factors promote oxidative stress.
• To highlight the role of oxidative stress in the development and progression of rheumatoid arthritis.
• To explore the potential of antioxidants as an integrative treatment for RA.

Main Methods:

• Literature review of studies investigating oxidative stress and rheumatoid arthritis.
• Analysis of the relationship between RA risk factors and oxidative stress.
• Synthesis of evidence regarding the impact of OS on RA pathology.

Main Results:

• Oxidative stress significantly contributes to DNA, lipid, and protein damage in RA.
• Environmental factors, diet, and gut microbiota imbalances exacerbate OS in RA patients.
• Antioxidant interventions show promise in mitigating RA-associated damage.

Conclusions:

• Understanding the multifaceted role of OS in RA is crucial for developing effective treatments.
• Antioxidants represent a valuable addition to RA management strategies.
• Recommendations for dietary and lifestyle modifications may benefit RA patients by reducing OS.
