OBJECTIVE: Glucocorticoid-induced osteonecrosis is a serious debilitating health problem. In the present study, we investigated the effects of alpha-lipoic acid on glucocorticoid-induced osteonecrosis in rats.

MATERIALS AND METHODS: A total of 40 male Wistar albino rats were equally assigned to 4 groups as control, methylprednisolone acetate (MPA), alpha-lipoic acid (ALA), and methylprednisolone acetate with alpha-lipoic acid (MPA+ALA). The animals in MPA group subcutaneously received 15 mg/kg/week for 2 weeks, whereas 100 mg/kg/day alpha-lipoic acid was intraperitoneal administered for 4 weeks to ALA group. The MPA+ALA group was subjected to both treatments in same doses. Osteonecrosis was confirmed and graded histologically. The serum concentrations of glucose, total cholesterol, low- and high-density lipoprotein, triglyceride, as well as the total oxidant and antioxidant status, oxidative stress index, prothrombin time and activated partial thromboplastin time were evaluated. Also, lipid peroxidation and DNA damage were immunohistochemically assessed in the bone.

RESULTS: Osteonecrotic lesions were narrower in the MPA+ALA group than in the MPA group (p<0.05). As compared to the controls, the biochemical parameters in MPA and MPA+ALA groups were significantly increased (p<0.001). The oxidative stress index was significantly higher in the groups with MPA than the controls (p=0.002), but the animals treated with ALA alongside MPA displayed lesser scores than the ones injected with solely MPA (p=0.03). The administration of MPA elevated lipid peroxidation and DNA damage, which were successfully alleviated by ALA.

CONCLUSIONS: Alpha-lipoic acid may be suggested to be a protective supplement in glucocorticoid-induced osteonecrosis in rats. The antioxidant capacity of alpha-lipoic acid may involve its beneficial effects.
