BACKGROUND To compare standard heparin (SH) and low molecular weight heparin (LMWH) in terms of anticoagulation, platelet activation and lipid metabolism, we selected 54 patients who had been on 4-hour hemodialysis three times weekly for at least 12 months, without bleeding disorders or dyslipidemic diseases. 28 were on hemodialysis with Polysulfone(More)
BACKGROUND While chronic renal damage is a condition with low-grade inflammation, the potential role of inflammation in kidney disease as a marker of cardiovascular damage is of current interest. This study analyzed the relationship between renal dysfunction, chronic inflammation, and extension of coronary atherosclerosis in patients with non-ST-segment(More)
The incidence of intradialytic disequilibrium syndrome and symptomatic hypotension has increased significantly among dialysis patients over the last ten years. Profiled hemodialysis (PHD) is a new technique, based on the intradialytic modulation of dialysate sodium concentration, which aspires to reduce to previous imbalances. This paper presents a new(More)
A mathematical model of solute kinetics for the improvement of hemodialysis treatment is presented. It includes a two-compartment description of the main solutes and a three-compartment model of body fluids (plasma, interstitial and intracellular). The main model parameters can be individually assigned a priori, on the basis of body weight and plasma(More)
A simple mathematical model of the intradialytic relationship between natraemia and dialysate sodium concentration is presented. The model includes a bicompartmental description of sodium, urea and fluid kinetics and an algebraic characterization of diffusive/convective mass-transfer across the dialysis membrane. Its ability to provide realistic responses(More)
BACKGROUND Among dialysis patients in the last 10 years the incidence of intradialytic dysequilibrium syndrome and symptomatic hypotension has increased significantly. Profiled haemodialysis (PHD), a new dialysis technique based on intradialytic modulation of the dialysate sodium concentration according to pre-elaborated individual profiles, has been set up(More)
Diseases of the cardiovascular system are a common cause of death in renal transplanted patients. In this study we assessed the echocardiographic morphological and functional findings after renal transplantation of two homogenous groups of transplanted patients with normal renal function. The first (A) with spontaneously normotensive patients, the second(More)
BACKGROUND Kidney transplant recipients (KTRs) manifest hypercoagulable state that contributes to an increased incidence of deep vein thrombosis (DVT), not only early but also late in their course. KTRs display an imbalance of hemostatic mechanisms with a multifactorial rise in procoagulant factors, partly related to traditional risk factors and partly to(More)
