Antioxidant Enzyme Activity and Malondialdehyde Concentration in patients with Urticaria Induced By Non Steroidal Anti-Inflammatory Drugs.
Annals Punjab Med Coll Jan ;6(2):110-4.

Objective: The Urticaria caused by NSAIDs was studied for their antioxidant enzyme activity and malondialdehyde (MDA) concentration. Methodology: Patients were divided into two groups; group one act as a control and the remaining group was urticaria patients. The levels of the Thiobarbituric acid reactive substances (TBARS, as a marker of lipid peroxidation), superoxide dismutase (SOD), glutathione (GSH) and catalase (CAT) in the serum were estimated. The enzymatic activity was estimated and compared with different categories of NSAIDs. Results: In present study CAT, SOD and lipid peroxidation product (MDA) were statistically different from that of healthy control and showed significant changes (p< 0.05) while GSH showed a non-significant (p>0.05) value. Conclusion: It is concluded that antioxidative system of the body is accelerated and shows variations in the patient of Urticaria. Moreover, present study shows the co-ordinated enzymatic mechanism and the interrelationship between enzymatic activities in allergy.
