BACKGROUND Treatment of secondary hyperparathyroidism with vitamin D and calcium in patients receiving dialysis is often complicated by hypercalcemia and hyperphosphatemia, which may contribute to cardiovascular disease and adverse clinical outcomes. Calcimimetics target the calcium-sensing receptor and lower parathyroid hormone levels without increasing(More)
To investigate the possible role of cytokines in the mediation of glomerular injury in the nephrotic syndrome, the levels of interleukin (IL)-1 beta, IL-2, interferon (IFN)-alpha, IFN-gamma, and tumor necrosis factor-alpha (TNF-alpha) were measured in patients with primary nephrotic syndrome. These patients had minimal change nephropathy (MCN), focal and(More)
The clinical benefits of using "biocompatible" neutral pH solutions containing low levels of glucose degradation products for peritoneal dialysis compared with standard solutions are uncertain. In this multicenter, open-label, parallel-group, randomized controlled trial, we randomly assigned 185 incident adult peritoneal dialysis patients with residual(More)
BACKGROUND/AIMS Darbepoetin alfa is an erythropoiesis-stimulating protein that works via the same mechanism and has a threefold longer serum half-life than recombinant human erythropoietin (rHuEPO). The objective of this study was to evaluate extending the dosing interval of darbepoetin alfa to once every other week administration for the treatment of(More)
BACKGROUND Patients with end-stage renal disease requiring hemodialysis are frequently treated with epoetin alfa (recombinant human erythropoietin, rHuEPO) for anemia. The aim of this study was to determine whether successful management of anemia could be maintained by changing the dosing schedule of epoetin alfa from 2 or 3 times per week to once-weekly(More)
We report the case of a patient on dialysis for 13 years, including continuous ambulatory peritoneal dialysis (CAPD) for 11 years, who developed sclerosing peritonitis with gross peritoneal calcification. The patient first presented with abdominal pain in January 1990, when peritoneal calcification was detected for the first time. Her symptoms settled(More)
BACKGROUND Current clinical practice guidelines recommend a native arteriovenous fistula (AVF) as the vascular access of first choice. Despite this, most patients in western countries start hemodialysis therapy using a catheter. Little is known regarding specific physician and system characteristics that may be responsible for delays in permanent access(More)
BACKGROUND A kidney transplant recipient inadvertently contracted donor-origin melanoma, which was found to be very advanced at presentation. Withdrawal of immunosuppression failed to induce rejection, and interferon-alpha was required. When florid allograft rejection was in progress, the allograft was removed, before it was recognized that the transplanted(More)
OBJECTIVE Research into the association between psychosocial factors and depression in End-Stage Renal Disease (ESRD) has expanded considerably in recent years identifying a range of factors that may act as important risk and protective factors of depression for this population. The present study provides the first systematic review and meta-analysis of(More)
