Patients with chronic kidney disease (CKD) experience many complications related to inflammation and oxidative stress that are closely related to the progression of kidney failure and increased mortality. Furthermore, these patients may have intestinal dysbiosis associated with persistent uremia, generating greater production of uremic toxins arising from the metabolism of intestinal bacteria and also helping to maintain the inflammatory process and oxidative stress. In this context, some nutritional strategies have been proposed as an adjuvant therapeutic alternative to modulate inflammation and improve the antioxidant response of patients with CKD, and even more so to modulate the intestinal microbiota. Based on the consolidated knowledge of the role of nutrients and bioactive compounds on the expression of genes related to inflammation, oxidative stress, and also the modulation of the intestinal microbiota, cinnamon, a member of the Lauraceae family, has been widely used as a spice and traditional herbal medicine for centuries and has indicated beneficial benefits in cardiovascular diseases, obesity, diabetes. The bioactive compounds in cinnamomum, such as cinnamaldehyde, cinnamic acid, and cinnamate, can attenuate oxidative stress, inflammation, hyperglycemia, intestinal dysbiosis, and dyslipidemia, which are common complications in CKD patients. Therefore, the present project proposes a longitudinal clinical trial study that aims to evaluate the effects of cinnamomum on transcription factors and inflammatory markers, oxidative stress and modulation of intestinal health in patients with CKD on hemodialysis.
