It has been increasingly apparent that wasting and cardiovascular disease (CVD) is associated with a persistent systemic inflammatory response in end-stage renal disease (ESRD) patients. The reasons for the increased risk of inflammation in ESRD patients appear to be complex, including non-dialysis as well as dialysis-related factors. The combination of an(More)
INTRODUCTION Uremic toxins play a pivotal role in the development of systemic complications of chronic kidney disease (CKD), which are largely mediated by the activation of the immune system. Triggers of inflammation in CKD are largely unknown and strategies aiming to reduce circulating ligands that could start the inflammatory response are potentially(More)
BACKGROUND The mortality rate is high among end-stage renal disease (ESRD) patients, and recent evidence suggests that this may be linked to inflammation. The activity of interleukin-6 (IL-6) and its soluble receptor (sIL-6R) are markedly up-regulated in ESRD patients, and plasma IL-6 levels predict outcome in haemodialysis (HD) patients. However, it has(More)
BACKGROUND Circulating levels of cytokines and other inflammation markers are markedly elevated in patients with chronic renal failure. This could be caused by increased generation, decreased removal, or both. However, it is not well established to what extent renal function per se contributes to the uremic proinflammatory milieu. The aim of the present(More)
From the immunologic viewpoint, chronic kidney disease (CKD) is characterized by disorders of both the innate and adaptive systems, generating a complex and still not fully understood immune dysfunction. Markers of a chronically activated immune system are closely linked to several complications of CKD and represent powerful predictors for mortality in the(More)
OBJECTIVE To investigate if intraperitoneal and systemic interleukin-6 (IL-6) and soluble IL-6 receptor (sIL-6R) are related to each other and to peritoneal solute transport rate (PSTR). DESIGN Longitudinal study in retrospectively selected patients. SETTING Peritoneal dialysis (PD) unit of a university-based hospital. PATIENTS AND METHODS 31 PD(More)
Symptomatic intradialytic hypotension (IH) continues to be an important complication of hemodialysis treatment. It has been suggested that patients with left ventricular (LV) diastolic dysfunction may be more sensitive to the effects of reduced cardiac filling. Left atrial volume index (LAVi) reflects the chronicity of exposure to elevated LV filling(More)
BACKGROUND AND OBJECTIVES Peritonitis remains as the most frequent cause of peritoneal dialysis (PD) failure, impairing patient's outcome. No large multicenter study has addressed socioeconomic, educational, and geographic issues as peritonitis risk factors in countries with a large geographic area and diverse socioeconomic conditions, such as Brazil.

Chronic kidney disease (CKD) is highly prevalent and a multiplier of cardiovascular disease (CVD) and cannot be completely explained by traditional Framinghan risk factors. Consequently, greater emphasis has been placed in nontraditional risk factors, such as inflammation, endothelial dysfunction, sympathetic overactivation, protein-energy wasting oxidative(More)
