Oxidative stress plays a significant role in the pathogenesis of inflammatory bowel disease (IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC). IBD is a chronic immune-mediated condition affecting the digestive system, with the exact cause still unclear. However, dysfunctional immunoregulation, particularly involving reactive oxygen species (ROS) and reactive nitrogen species (RNS), is believed to be a key factor. These molecules are produced in abnormally high levels in IBD and contribute to disease initiation and progression by damaging the gut lining and activating inflammatory pathways. Oxidative stress markers such as malondialdehyde (MDA), 8-hydroxy-2'-deoxyguanosine (8-OHdG), and serum-free thiols (R-SH) are elevated in IBD patients and correlate with disease severity. These markers can be used for diagnosis and monitoring treatment response. Antioxidants such as vitamin C, vitamin E, glutathione, and N-acetylcysteine are being explored as potential treatments for IBD. Oxidative stress in IBD is associated with the overproduction of ROS, damage to biomolecules, mitochondrial dysfunction, immune cell recruitment, and impaired antioxidant defense. ROS can damage lipids, proteins, and DNA, leading to oxidative stress and inflammation. Mitochondrial dysfunction is also implicated in IBD, with studies showing that mitochondrial dysfunction can contribute to the disease's pathogenesis. The activation of inflammatory pathways, such as NF-κB and Nrf2, is also linked to oxidative stress in IBD. These pathways regulate gene expression and inflammatory responses, contributing to the disease's progression. The role of oxidative stress in IBD is complex, with ROS and RNS playing a critical role in the development and progression of the disease. The overproduction of ROS and RNS in IBD leads to oxidative and nitrosative stress, which can damage the gut lining and activate inflammatory signaling pathways. Oxidative stress markers can be used for diagnosis and monitoring treatment response, and antioxidant therapies are being explored as potential treatments for IBD. The study highlights the importance of understanding the mechanisms of oxidative stress in IBD and developing targeted therapies to manage and treat the disease.Oxidative stress plays a significant role in the pathogenesis of inflammatory bowel disease (IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC).
