BACKGROUND We conducted a pilot trial to compare the effectiveness and safety of 2 different treatments in patients with membranous nephropathy and nephrotic syndrome. METHODS To validate the hypothesis that the 2 treatments were equivalent, patients with biopsy-proven membranous nephropathy and nephrotic syndrome were randomly assigned to(More)
Autologous arteriovenous fistulas (AVF) have the best 5-yr patency and the lowest complication rate among hemodialysis vascular accesses. However, maturation requirements to optimize survival are unknown. A longitudinal cohort study was conducted to ascertain risk factors for failure, maturation time, and survival of the first AVF. All patients who(More)
In the last years, the number of hemodialysis (HD) patients with erythropoietin (rHuEPO) resistance is increasing. Probably, central venous catheters (CVCs) contribute to this resistance by inducing inflammation and oxidative stress. This study was aimed to compare vitamin E-bonded dialyzer (PSVE) versus polyethersulfone membrane. Sixteen subjects with CVCs(More)
Bioimpedance is a simple and non-invasive method of assessing body fluid composition. The aim of our study was to evaluate the reilability of impedance: a) to measure urea distribution volume considered to be coextensive with total body water (TBW); b) to assess the changes in body fluid compartments before and after dialysis; c) to predict hypotensive(More)
Blood flow rate is a critical factor in the achievement of an adequate dialysis dose. The aim of this review is to evaluate the possibility of optimizing dialysis dose in terms of Kt/V in patients with reduced vascular access (VA) flow rate, considering effective blood flow (Qb eff), recirculation, access flow and hemodialyzer. In patients where the(More)
BACKGROUND Leptin is a protein produced by fat cells and involved in body weight regulation. In patients with normal kidney function, leptin has been considered an independent predictor of cardiovascular events. In uremic patients, leptin in plasma serum was assumed to be associated with malnutrition, inflammation and atherosclerosis. Because of its(More)
BACKGROUND Arteriovenous fistulae survive longer than grafts and catheters. However, their short term outcomes may not be as good. We sought to determine whether fistulae created in patients referred to a nephrologist less than 3 months before dialysis start show higher risk of unsuccessful use and early failure. METHODS All patients receiving a new(More)
This paper presents an overview of the project carried out by the Vascular Access (VA) Working Group of the Italian Society of Nephrology with the aim of developing 4 position papers at the national level on how to choose, use, and implant the different, possible types of vascular access. The topics of the project are: 1) recommendations on the use of(More)
UNLABELLED Permanent dual lumen catheters (PDLC) provide an alternative vascular access in patients considered unsuitable for arteriovenous fistula, graft or peritoneal dialysis. However, the use of PDLC is often complicated by inadequate blood flow. The aim of this study was to identify catheter dysfunctions. We studied prospec-tively 57 chronic(More)
