Markers of Oxidative Stress in Inflammatory Bowel Diseases: Risk Factors and Implications for a Dietetic Approach

Plain-language summary

Inflammatory bowel disease (IBD), including Crohn's disease (CD), Ulcerative Colitis (UC) and IBD-unclassified (IBD-U) is a chronic inflammatory intestinal disorders that affect both children and adults. Patients with IBD can present with severe gastrointestinal symptoms, require frequent hospitalizations, expensive medical treatments and can develop invalidating complications requiring surgery. The incidence of IBD is increasing worldwide. The pathogenesis is multifactorial with immunological, environmental and genetic factors contributing to the disease. There is evidence that oxidative stress (OS) imbalance is involved in IBD onset and evolution, although the exact contribution to the pathogenes is unclear. An antioxidant dietetic approach is promising as an adjunctive treatment of IBD. The main aims of this project are to characterize the OS imbalance in IBD in relation to disease's features and to genetic factors and to evaluate the efficacy of an antioxidant dietetic treatment
