BACKGROUND
The aim of this study was to evaluate oxidative stress and to determine the activity of paraoxonase and arylesterase in patients with osteomyelitis compared to healthy controls.
METHODS
In total, 30 patients diagnosed with osteomyelitis and 30 healthy volunteers were enrolled in the study. Paraoxonase and arylesterase activities were measured spectrophotometrically. Serum lipid hydroperoxide (LOOH) concentrations were measured by ferrous oxidation with xylenol orange (FOX) assay as markers of oxidative stress.
RESULTS
Serum paraoxonase and arylesterase activities were significantly lower in patients with osteomyelitis compared to control individuals (all p < 0.05). Serum LOOH concentrations were significantly higher in patients with osteomyelitis than those in controls (p < 0.05). Arylesterase activity was inversely correlated with triglyceride (r =- 0.49; p = 0.005) and cholesterol concentrations (r =- 0.41; p = 0.025).
CONCLUSIONS
In light of the findings obtained from the present study, it may be assumed that decreased activity of serum paraoxonase and increased concentrations of LOOH observed in osteomyelitis patients appear to be related to the increased oxidative stress and inflammatory conditions present in these patients, and may cause a much more severe status of the disease.
