BackgroundOsteomyelitis (OM) is a local or generalised infection of the bone and bone marrow which may be multifactorial in its causation. In this study, we aimed to determine oxidative DNA damage and antioxidant status of patients with chronic osteomyelitis.Material MethodIn this study, patients with chronic osteomyelitis and healthy controls were compared for descriptive characteristics (age and gender) and serum levels of malondialdehyde (MDA), 8-hydroxy-2-deoxy guanosine and antioxidant enzymes catalase, glutathione and superoxide dismutase.ResultsThis was a case-control study. About 5 mL of venous blood was collected for the estimation of biochemical parameters. This study comprised of 36 OM patients diagnosed, and 41 healthy ages (25-55 years) and sex-matched individuals. Antioxidant enzyme levels were significantly lower in patients with OM, whereas MDA and oxidative DNA damage levels were significantly higher.ConclusionThe results obtained from this study have shown that the oxidant-antioxidant balance is impaired in patients with chronic osteomyelitis. It also supports that chronic osteomyelitis has associated with oxidative DNA damage.© 2021 John Wiley & Sons Ltd.
