The aim of this study was to investigate the role of hydroxychloroquine (HCQ)-induced oxidative stress on
sciatic nerve and muscle tissues of rats. The oxidant/antioxidant parameters in the sciatic nerve and muscle
tissues were analyzed, and stereological analysis of the sciatic nerve was performed. Levels of malondialdehyde
and nitric oxide in the tissues were significantly higher in the HCQ group than in the control group (
p < 0.05).
In addition, activities of superoxide dismutase and glutathione peroxidase were found to be significantly higher
in the HCQ group than the control group (
p < 0.05). There were significant decreases in nerve fiber diameter
and myelin sheet thickness in the HCQ group compared with the control group (
p < 0.05). These results
revealed that HCQ might increase oxidative stress on sciatic nerve and muscle tissues of rats, which may
correlate with axonal atrophy in sciatic nerves.
