Brief Summary

Patients with Chronic Kidney Disease (CKD) have many complications associated with inflammation, oxidative stress and intestinal dysbiosis, which are closely related to the progression of kidney failure and cardiovascular disease. Sulforaphane, an isothiocyanate found in cruciferous vegetables (Family: Brassicaceae) is recognized as one of the most important activators of erythroid nuclear factor 2 related to factor 2 (Nrf2). However, clinical evidence to assess the effects of sulforaphane in patients with CKD is scarce, and there are no studies that have investigated its effects on the expression of genes and markers related to inflammation in these patients. Thus, the present project proposes a longitudinal study of the clinical trial type that aims to evaluate the effects of sulforaphane on transcription factors and inflammatory markers in patients with CKD.

Study Arms (2)

Sulforaphane Group

EXPERIMENTAL

Administration of 4g L-sulforaphane per day, for 2 months and after the washout period (2 months) the groups will be crossed and will receive the same amount of placebo as the other group for 2 months.

Dietary Supplement: L-sulforaphane 1%

Placebo Group

PLACEBO COMPARATOR

Administration of 4g of corn starch colored with chlorophyll, per day, for 2 months and then after the washout period (2 months) the groups will be crossed and will receive the same amount of sulfarophane as the treatment group.

Dietary Supplement: Placebo Group
