Özet
Objective: We have measured ischemia-modified albumin (IMA), total antioxidant status (TAS), total oxidant status (TOS) and high-sensitivity C-reactive protein (hsCRP) levels in obese and normal-weight subjects to investigate if IMA can be used as a biomarker of oxidative stress and inflammation and if IMA was an independent determinant of obesity or not. Methods: The study was performed on 92 obese subjects (20 male, 72 female) aged 38 +/- 11 years and 78 normal-weight controls (19 male, 59 female) aged 37 +/- 11 years. Serum lipids, IMA, TAS, TOS, and hsCRP levels of the subjects were measured. Results: IMA (p < 0.05), TOS (p < 0.001), and hsCRP (p < 0.001) levels of the obese subjects were significantly higher, whereas TAS levels were significantly lower (p < 0.05) than those of the controls after adjustment for age and gender. In the linear regression analysis, waist circumference (r(2) = 0.139, p < 0.01), BMI (r(2) = 0.136, p < 0.01) and insulin (r(2) = 0.120, p < 0.05) were shown to be significant independent determinants of IMA levels. Conclusions: We have found that oxidative stress and inflammation were increased and antioxidative defense was decreased, which resulted in increased levels of IMA, a biomarker of ischemia, in obese subjects. Also, obesity and insulin were found to be independent determinants of IMA. Thus, obese subjects are under high risk of ischemia, and IMA may be used as a biomarker of oxidative stress and ischemia. Further larger investigations are needed to confirm this opinion. Copyright (C) 2012 S. Karger GmbH, Freiburg
