Effects of Jaboticaba (Plinia Cauliflora) Supplementation in Chronic Kidney Disease Patients

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.

Beetroot Extract Supplementation Associated With an Exercise Protocol for Chronic Kidney Disease Patients

Chronic kidney disease (CKD) patients often present systemic inflammation and oxidative stress, resulting in metabolic disorders and high rates of disease-associated cardiovascular death. The literature has indicated that dietary control, the use of bioactive compounds, and the practice of regular physical exercise are essential for the prevention and management of CKD and its complications. In this context, beetroot (Beta vulgaris rubra) deserves attention as it is a source of several bioactive compounds, such as nitrate, betaine, and betalain, with beneficial effects for CKD patients, including anti-inflammatory, antioxidant effects, reduction of blood pressure, and vasodilatory action. The antioxidant and anti-inflammatory properties, in addition to their vasodilatory and antihypertensive capacity, can make supplementation of beetroot an excellent nutritional strategy to help in the treatment of CKD patients. So, this research project will bring contributions to the scientific world, providing strategies for application in clinical practice and the care of patients with CKD, on the use of beetroot associated with an exercise protocol as a non-pharmacological strategy in modulating inflammation, oxidative stress, and improved functional capacity. Furthermore, when supplemented hours before physical training, has been identified as an important factor in improving performance in these activities. Therefore, this study aims to evaluate the effects of supplementation (acute and chronic) of beetroot extract associated with an exercise protocol on complications associated with CKD.
