Study of Lipid per Oxidation and Enzymatic Antioxidant Activity in Rheumatoid Arthritis: Relation with Disease Activity

Background: Rheumatoid Arthritis (RA) is one of the known Autoimmune diseases in patients with age group of 25 to 60. A significant aspect of disease development should be Reactive Oxygen Species (ROS). Few studies have shown an association between oxidative stress and RA disease activity. This study was therefore intended to examine whether there is a link between oxidative stress and disease activity.

Methods and Materials: This case-control study on 120 individuals was conducted. In accordance with the Disease Activity Score (30) were healthy controls with 90 RA patients in mild (30), moderate (30) and severe (30). Malondialdehyde Measured Lipid Per Oxidation (MDA). Antioxidant enzyme activities such as Superoxide Dismutase (SOD), Catalase (CAT) and glutathione peroxidase (GPX) have been also measured. A correlation coefficient was also used to evaluate the strength of the link between oxidative stress and activity of the illness.

Results: the MDA levels in all the RA subgroups were substantially higher than those in the control group, but the activity of antioxidant enzymes was significantly lower. Between Malondialdehyde Measured Lipid Per Oxidation (MDA) and Disease Activity score of 28 RA patients (DAS28) there were positive correlations.

Conclusion: Significant increase in RA patients' lipid per oxidization supports the role of oxidative stress in RA aetiology and the usage of MDA for disease control.
