Optimizing haemodialysate composition.

Survival and quality of life of dialysis patients are strictly dependent on the quality of the haemodialysis (HD) treatment. In this respect, dialysate composition, including water purity, plays a crucial role. A major aim of HD is to normalize predialysis plasma electrolyte and mineral concentrations, while minimizing wide swings in the patient's intradialytic plasma concentrations.

Current Evidence in Haemodiafiltration.

Background: Standard low-flux haemodialysis (HD) is not very efficacious, and patient morbidity and mortality rates are still very high. According to the initial study design, the MPO study reported that high-flux HD (hf-HD) showed a significant 37% relative risk reduction of mortality in patients with serum albumin ≤4 g/dl; online haemodiafiltration (HDF) is considered the most efficient technique of using high-flux membranes, as clearances of small solutes, like urea, are higher than in haemofiltration and clearances of middle solutes, like β2-microglobulin, are higher than in hf-HD.

Summary: Three randomized trials have recently been published analysing the effect of online HDF on mortality.

Phosphate binders for the treatment of hyperphosphatemia in chronic kidney disease patients on dialysis: a comparison of safety profiles.

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

Renal sympathetic nerve ablation for the treatment of difficult-to-control or refractory hypertension in a haemodialysis patient.

Haemodialysis patients show sympathetic hyperactivity. Hyperactivation of the sympathetic nervous system aggravates hypertension and it is related to left ventricular hypertrophy, heart failure, arrhythmias and atherogenesis. We report the first use of renal sympathetic nerve ablation for correction of uncontrolled hypertension in an end-stage renal disease patient on maintenance dialysis.

Palifermin in the management of mucositis in hematological malignancies: current evidences and future perspectives.

Background: In the management of hematological malignancies, chemotherapy-induced mucositis is an increasingly recognized problem, leading to potentially severe clinical complications, treatment delays, increased costs and impairment of patient's quality of life. Many forms of cytotoxic treatments given in this setting may induce several degrees of mucositis. In particular, conditioning therapy with hematopoietic stem cell transplantation (HSCT) induces a disruption of the mucosal barrier function throughout the entire gastrointestinal tract facilitating the spreading of bacteria and endotoxin with subsequent increased risk of septicemia and, in the allogeneic setting, a worsening of Graft Versus Host Disease (GVHD).
