BACKGROUND Automatic systems for stabilizing blood pressure (BP) during dialysis are few and only control those variables indirectly related to BP. Due to complex BP regulation under dynamic dialysis conditions, BP itself appears to be the most consistent input parameter for a device addressed to preventing dialysis hypotension (DH). METHODS An automatic(More)
We report a case of deep vein thrombosis in a young man with idiopathic nephrotic syndrome and resistance to activated protein C. We postulate that patients with concurrent nephrotic syndrome and factor V may have an increased risk of thrombosis. Screening for factor V Leiden may be indicated in patients with idiopathic nephrotic syndrome.
Dual-lumen cuffed central venous catheter proved an important alternative vascular access compared to conventional arteriovenous (Cimino-Brescia) shunt in a selected group of patients on regular dialysis treatment. Typically, these catheters are used as bridging access, until fistula or graft is ready for use, or as permanent access when an arteriovenous(More)
We report the case of a patient with Takayasu's arteritis, nephrotic syndrome, and pANCA. The kidney biopsy specimen showed the classic features of IgA nephropathy. The course of this patient supports the view that the glomerular and vasculitic involvements of Takayasu's arteritis may result from a common immunologic mechanism, and cases with urinary(More)
Twenty uremic patients submitted to three different dialytic procedures (6 patients to acetate dialysis, 8 patients to bicarbonate dialysis, 6 patients to hemofiltration) were monitored in respect to the hemodynamic parameters recorded with a thermistor Swan-Ganz catheter. During acetate dialysis there was an increment of cardiac index (CI) up to positive(More)
In this work the production of auto-assembled nanoparticles obtained by the mixing of chitosan and lecithin is presented. The size and surface charge of the nanoparticles were studied as function of the weight ratio between components, the viscosity of the polysaccharide and the pH of the colloidal suspension. In order to elucidate the structure of(More)
The internal jugular vein (IJV) should be the preferred form of venous vascular access for the placement of dialysis catheters. 'Blind' puncture or 'skin mark' ultrasound technique puncture present multiple complications due to the significant variations in IJV location in normal subjects and even more so in uremic pa-tients. The aim of this study is to(More)
