Clinical Trial Summary

The objective of this study is to evaluate the supplementation with tocotrienol, a vitamin E compound on inflammation, oxidative stress, and microbiota on Chronic Kidney Disease patients.

Description:

In Chronic Kidney Disease (CKD), inflammation and oxidative stress are common statuses, which are aggravated by renal replacement therapy such as hemodialysis. Currently, intestinal microbiota imbalance has been associated with both inflammation and oxidative stress. In this regard, strategies in the management of this framework are necessary. It has been observed that vitamin E plays an important role in the modulation of transcription factors involved in inflammation such as NF-kB and Nrf2, acting on cell membrane protection and tissue recovery. Its benefits have been proven both in renal and intestinal health, however, studies analyzing the vitamin E supplementation in the modulation of intestinal microbiota with consequent effect on CKD and its reflexes are scarce. Thus, the current randomized, double-blind, placebo-controlled study will evaluate the effects of vitamin E supplementation on the modulation of the expression of nuclear cytokine (NF-kB e Nrf2), activators and inhibitors, as well as, on inflammation and oxidative stress and on the modulation of the intestinal microbiota in patients CKD.
