%X Resveratrol, a phenolic compound found in various plants, including grapes, berries, and peanuts, shows promise for the treatment of cancer, aging, type 2 diabetes, and cardiovascular diseases. Resveratrol can promote transcription factor nuclear factor-erythroid 2-related factor 2 (Nrf2) activation, increase the expression level of SIRT-1, which is a sirtuin family protein, and reduce mTOR pathway signaling. This compound has anti-inflammatory properties in that it inhibits or antagonizes the nuclear factor- B (NF- B) activity, which is a redox-sensitive transcription factor that coordinates the inflammatory response. Inflammation and oxidative stress, which are common features in patients with chronic kidney disease (CKD), are interrelated and associated with cardiovascular disease and the progression of CKD itself. Because of the modulation of the mechanisms involved in the inflammatory-oxidative stress cycle, resveratrol could play an important role in controlling CKD-related metabolic derangements. Although resveratrol supplementation in theory is a promising therapy in this patient group, there are no studies evaluating its effects. Thus, the present review aims to describe the role of resveratrol in inflammation and oxidative stress modulation and its possible benefits to patients with CKD. 1. Introduction Systemic inflammation and oxidative stress are nontraditional risk factors that are associated with premature cardiovascular disease commonly observed in patients with chronic kidney disease (CKD) [1, 2]. Oxidative stress, which is characterized by an imbalance between oxidative free radical production and antioxidant capacity, appears to be the link between inflammation and cardiovascular disease in dialysis patients [3]. Moreover, in nondialysis CKD stage, oxidative mechanisms can be involved in renal tissue injury, in which the oxidative stress is associated with the progression of CKD itself [4, 5]. Resveratrol, a phenolic compound that is found in various plants, especially including red grapes and their derivatives [6], has demonstrated many beneficial effects, including anti-inflammatory and antioxidant roles by enhancing the production of antioxidant enzymes [7] and modulating nuclear factors involved in the inflammation-oxidative stress cycle [8, 9]. However, no study has investigated the effects of resveratrol on patients with CKD. This review presents exciting evidence of the positive role of resveratrol in inflammation and oxidative stress control, and the study argues how resveratrol may represent an important link in the puzzle of
