This work aims to evaluate the effects of the association of green propolis extract with royal jelly on inflammation and oxidative stress in participants with chronic kidney diseases (CKD) and Systemic arterial hypertension (SAH), in a longitudinal, randomized, double-blind, placebo-controlled clinical trial that will be carried out for 2 months.

The aim of this study is to evaluate the effects of Brazil nut supplementation on inflammation, oxidative stress and intestinal microbiota in patients with chronic kidney disease undergoing conservative treatment.

The increase prevalence of chronic kidney disease (CKD) over the years represent a significant public health problem. The role of inflammation and oxidative stress in the pathophysiology of CKD, as well as progression and comorbidities, is already well consolidated. The gut microbiota composition imbalance may also be a risk factor contributing to the increased conditions mentioned above, and to uremic toxins release and endotoxemia. The literature has indicated the use of bioactive compounds as a nonpharmacological treatment strategies for the management of non-communicable diseases (NCDs), such as CKD and its complications. In this context, jaboticaba (Plinia Cauliflora) emerges as a potential therapeutic approach as it is a source of phenolic compounds, such as anthocyanins, flavonols, ellagitannins, and phenolic acids. Such phenolic compounds may have beneficial effects in patients with CKD, such as anti-inflammatory, antioxidant, modulation of the intestinal microbiota, hypotensive and hypoglycemic effects. These combined effects can help manage risk factors and CKD itself, and associated complications. Therefore, this research project aims to add scientific knowledge, providing a non-pharmacological therapeutic approach to be implemented in clinical practice and in the care of patients with CKD, with the aim of modulating inflammation, oxidative stress, microbiota composition, and improving the quality of life of these patients. Therefore, this study aims to evaluate the effects of jaboticaba (Plinia Cauliflora) supplementation on complications associated with CKD.
