The Effect of L-Carnitine Treatment on Levels of Malondialdehyde and Glutathione in Patients with Age Related Macular Degeneration

Abstract

Abstract

Objective: The aim of this study was to determine the antioxidant properties of the L-carnitine (LC) in the treatment of patients with age-related macular degeneration (AMD).

Materials and Methods: This study involved 60 patients diagnosed with early AMD. The patients were divided into two groups. Group I was the study group that received LC supplementation for 3 months. Group II was the control group and did not consent to LC supplementation over the 3 months. At the end of the 3-month period, markers of lipid peroxidation, malondialdehyde (MDA) and reduced glutathione (GSH) were measured in the two groups.

Results: In the study group, the MDA level was significantly reduced, while the GSH level was significantly increased at the end of the 3-month period (P<0.001).

Conclusion: Our results suggest that LC may protect against oxidative damage by decreasing the MDA level, a marker of lipid peroxidation, and increasing GSH.
