Abstract
It has been well-known for many years now that vitamin E is an essential nutrient; however, some of the physiological functions of this vitamin are still far from being understood. In recent years, a series of preclinical and clinical studies proposed a protective role of vitamin E on acute kidney injury (AKI), which has a high morbidity rate and mortality rate in clinical investigations. Based on the benefits associated with vitamin E, such as strong antioxidant function, low toxicity, rare side-effects, and low cost, this therapy strategy has garnered an extensive amount of interest in the scientific community for the development of new therapy modes against AKI. In this review, a concise overview of the application of vitamin E in the treatment of AKI is provided as well as a summary of a series of published data regarding the combination therapy modes and detailed therapy mechanisms of vitamin E-based therapy against AKI. At present, there are critical points of this therapy mode that are still in need of further clarification, meaning the current understanding of the role of vitamin E in the treatment of AKI remains incomplete. However, the development of more reliable pharmacological or biotechnical strategies with vitamin E for the eventual treatment of patients with AKI may guide the next chapter of vitamin E research.
