Abstract
SummaryBackground: We aimed to determine the levels of total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI) and paraoxonase1/arylesterase levels in inflammatory bowel disease (IBD), and the relation be - tween these molecules and the activity index of the disease. Methods: Eighty IBD patients (ulcerative colitis (UC)/Crohn disease (CD) 40/40) and 80 control group participants were included in the study. Oxidative stress parameters were measured using the colorimetric method. As disease activity indexes, the endoscopic activity index (EAI) was used for UC and the CD activity index (CDAI) was used for CD. Results: In IBD patients, mean TAS (1.3±0.2 vs 1.9±0.2, respectively; p<0.001) and arylesterase (963.9±232.2 vs 1252.9±275, respectively; p<0.001) levels were found to be lower and TOS level (5.6±1.6 vs 4.0±1.0, respectively; p<0.001) and OSI rate (4.5±1.6 vs 2.2±0.8, respectively; p<0.001) were found to be higher compared to the control group. A strong positive correlation was found between EAI and TOS levels (r=0.948, p<0.001) and OSI rate (r=0.894, p<0.001) for UC patients. A very strong positive correlation was found between EAI and TOS levels (r=0.964, p<0.001) and OSI rate (r=0.917, p<0.001) for CD patients. It was found in a stepwise regression model that C-reactive protein, OSI and arylesterase risk factors were predictors of IBD compared to the control group. Conclusion: Increased oxidative stress level in IBD patients and the detection of OSI rate as an independent predictor for disease activity indexes lead to the idea that oxidative stress might be related to the pathogenesis of IBD.
