Indoxyl sulfate (IS) is a uremic toxin that accelerates the progression of chronic kidney disease (CKD). AST-120 (Kremezin®; Kureha Corporation, Tokyo, Japan) removes indole, which is the precursor of IS, in the intestine, and reduces the accumulation of IS. This drug has been shown to retard the deterioration of renal function in CKD patients through reducing the levels of IS. IS was reported to promote aortic calcification and stimulate the proliferation of vascular smooth muscle cells (VSMC). IS also inhibits endothelial proliferation and wound repair. With this background, the investigators will performed the study whether AST-120 improve the endothelial dysfunction in CKD patients.
Introduction: Chronic Kidney Disease (CKD) is considered an important public health problem, with prevalence of 9.6% in our population. The CKD has as main symptoms fatigue, muscle weakness and poor exercise tolerance, which directly contribute to physical inactivity and low mobility, increasing the risk of morbidity and mortality in CKD patients with significant impact on quality of life of these patients. Thus, patients with CKD have poor quality of life, high incidence of cardiovascular diseases, high prevalence of endothelial dysfunction, the consequent increase in arterial stiffness and serum concentration of asymmetric dimethylarginine (ADMA). It is believed that the conditioning of these patients may reduce cardiovascular risks and improve the quality of life. Aim of the study: Evaluate the impact of exercise training in relation to functional capacity, quality of life, pulse wave velocity and ADMA in patients with CKD on dialysis. Materials and methods: Is a randomized controlled study, with 34 CKD patients on conservative treatment, divided into control group (with stretching exercises and metabolic exercises) and training group, those undergoing physical training, aerobic and resistance during six months. Before and after exercise training, patients will be assessed using the SF-36 and IPAQ. Also be held assessment of pulse wave velocity, measurement of serum ADMA and spirometry testing. Statistical analysis consisted of t test for independent data or chi-square when appropriate.
