Background For some patients with end-stage renal disease (ESRD), providing conservative care until death may be an acceptable alternative for renal replacement therapy (RRT). We aimed to estimate the occurrence of conservative care in Europe and evaluated opinions about which factors nephrologists consider important in their decision not to offer RRT. Methods With a web-based survey sent to nephrologists in 11 European countries, we inquired how often RRT was not started in 2009 and how specific factors would influence the nephrologists’ decision to provide conservative care. We compared subgroups by nephrologist and facility characteristics using chi-square tests and Mann–Whitney U tests. Results We received 433 responses. Nephrologists decided to offer conservative care in 10% of their patients [interquartile range (IQR) 5–20%]. An additional 5% (IQR 2–10%) of the patients chose conservative care as they refused when nephrologists intended to start RRT. Patient preference (93%), severe clinical conditions (93%), vascular dementia (84%) and low physical functional status (75%) were considered extremely or quite important in the nephrologists’ decision to provide conservative care. Nephrologists from countries with a low incidence of RRT, not-for-profit centres and public centres more often scored these factors as extremely or quite important than their counterparts from high-incidence countries, for-profit centres and private centres. Conclusions Nephrologists estimated conservative care was provided to up to 15% of their patients in 2009. The presence of severe clinical conditions, vascular dementia and a low physical functional status are important factors in the decision-making not to start RRT. Patient preference was considered as a very important factor, confirming the importance of extensive patient education and shared decision-making. [ABSTRACT FROM PUBLISHER]

Background. Strict control of serum calcium and phosphate concentrations is paramount to prevent secondary hyperparathyroidism in haemodialysis (HD) patients. Standard intermittent low-flux HD (Lf-HD) is not sufficient to reach this goal. The aim of this study was to evaluate the effect of on-line haemodiafiltration (Ol-HDF) on serum calcium (sCa), phosphate (sPO4) and parathyroid hormone (PTHint) concentrations.Methods. Of the 220 patients screened, 65 met the inclusion criteria for the study; 30 of whom agreed to participate in the study (Study group), the others were considered as the control group (Controls). Protocol for Study the group consisted of 6 months conventional Lf-HD (Period 1) and 6 months of post-dilutional Ol-HDF (Period 2). Controls continued their usual Lf-HD and were followed for 12 months. The main variables evaluated at the start and at the end of each period were sCa, sPO4 and PTHint.Results. The switchover from Lf-HD to Ol-HDF resulted in a significant reduction of sPO4 (from 5.1 ± 1.0 to 4.0 ± 0.7; P < 0.0001) and PTHint concentrations (from 307 ± 167 to 194 ± 98; P < 0.0001), no significant changes were found in both sCa concentrations (from 9.1 ± 0.7 to 8.9 ± 0.6) and phosphate binder dose. Kt/Vurea increased significantly, and beta2 microglobulin concentrations decreased significantly. In the Controls, no significant variations of the same variables were observed over time, except for a significant increase in sevelamer intake.Conclusion. This study supports the idea that Ol-HDF could be better than Lf-HD in controlling mineral metabolism in HD patients. [ABSTRACT FROM PUBLISHER]

Background. Dialysis increases patient life expectancy but is associated with clinically severe and costly complications. Health and economic benefits could derive from postponing dialysis with a supplemented very low-protein diet (sVLPD). [ABSTRACT FROM PUBLISHER]

Background. The effect of the adequacy of dialysis on the response to recombinant human erythropoietin (rHuEpo) therapy is still incompletely understood because of many confounding factors such as iron deficiency, biocompatibility of dialysis membranes, and dialysis modality that can interfere.
