New scenarios in secondary hyperparathyroidism: etelcalcetide. Position paper of working group on CKD-MBD of the Italian Society of Nephrology.

Bone mineral abnormalities (defined as Chronic Kidney Disease Mineral Bone Disorder; CKD-MBD) are prevalent and associated with a substantial risk burden and poor prognosis in CKD population. Several lines of evidence support the notion that a large proportion of patients receiving maintenance dialysis experience a suboptimal biochemical control of CKD-MBD. Although no study has ever demonstrated conclusively that CKD-MBD control is associated with improved survival, an expanding therapeutic armamentarium is available to correct bone mineral abnormalities.

Sodium removal and plasma tonicity balance are not different in hemodialysis and hemodiafiltration using high-flux membranes.

Background: The clinical benefits of on-line hemodiafiltration (HDF) versus high-flux membranes hemodialysis (hf-HD) are still debated. In fact, although a superiority of one treatment over the other, especially in terms of mortality, did not emerge from the analysis of clinical trials, improved intradialytic vascular stability and cardiovascular mortality have been observed in patients undergoing HDF rather than hf-HD; the lower removal of sodium (Na) during HDF seems to play a major role. The plasma concentration of Na is the major determinant of plasma tonicity, which, by determining the flow of water between the intracellular and the extracellular compartment, contributes to the vascular refilling process and the maintenance of blood pressure during the hemodialysis treatment.

Current and potential treatment options for hyperphosphatemia.

Introduction: Hyperphosphatemia is common in late stages of chronic kidney disease and is often associated with elevated parathormone levels, abnormal bone mineralization, extra-osseous calcification, and increased risk of cardiovascular events and death. Several classes of oral phosphate binders are available to help control plasma phosphorus levels. Although effective at lowering serum phosphorus, they all have safety, tolerability, and compliance issues that need to be considered when selecting which one to use.

Predictors of first ischemic lower limb ulcer in dialysis patients: an observational cohort study.

Background: Lower limb ischemia affects the quality of life, physical activity and life expectancy of dialysis patients. The aim of this study was to investigate the risk factors associated with ischemic foot ulcers considering clinical, laboratory and therapeutic domains.

Methods: This observational cohort study was based on data from the Nephrology and Dialysis Department database of Alessandro Manzoni Hospital, Lecco (Italy).
