RESUMO
INTRODUCTION: Osteomyelitis (OM) is a local or generalized infection of the bone and bone marrow which may be multifactorial in its causation. Chronic infection is characterised by sequestrum and involucrum formation. AIM: The present study has been carried out for assessing the oxidative stress in chronic OM by measurement of serum oxidants {such as malondialdehyde (MDA), protein carbonyl (PC), nitrite} and the serum antioxidants {such as ascorbic acid, superoxide dismutase (SOD), ceruloplasmin (Cp), blood glutathione} by spectrophotometric method. MATERIALS AND METHODS: This was a case control study. About 5 ml of venous blood was collected for the estimation of biochemical parameters. This study comprised of 50 OM patients diagnosed at SSLH Hospital, Varanasi and 50 healthy ages (15-35 y) and sex matched individuals. RESULTS: Significantly increased (p<0.0001) levels of serum oxidants and significantly decreased (p<0.0001) levels of all serum antioxidants except ceruloplasmin indicated significantly increased (p<0.0001) levels in response to infections in chronic OM patients as compared to the healthy controls. CONCLUSION: These results suggest that there occurs an imbalance between oxidants and antioxidants, especially an increase in oxidative stress, as measured by the levels of the parameters: serum MDA, serum protein carbonyl and serum nitrite.
