Oxidative stress and inflammatory parameters in adult patients presenting with celiac disease

Celiac disease is a chronic small intestinal inflammatory condition caused by an inappropriate immune response to gluten of wheat, rye and barley, with a prevalence of about 1: 100 in the Caucasian population when occurs a inflammatory response and seems to involve high levels of interleukins. Objective: Determine the presence of oxidative stress and inflammation in the gut of patients with CD. Methods: Transversal study that included patients undergoing upper gastrointestinal (GI) endoscopy was performed. The study population consisted 24 cases and 26 controls. The duodenal levels of protein carbonyls, thiobarbituric acid reactive species (TBARS), as well as catalase (CAT), superoxide dismutase (SOD) activities were measured. Gut levels of interleukin (IL) 6, 10 and 8 were also determined. The Marsh classification was recorded and used as a parameter of disease severity. Results: Both IL-6 and IL-10, but not IL8, were increased in CD patients when compared to healthy individuals. Oxidative damage parameters were increased while antioxidant defenses were decreased in our sample. Both IL6 levels and SOD activity were related to Marsh score. Conclusions: Different markers of inflammation and oxidative stress are altered in the gut of CD patients, and some of them are related to disease severity.
