Ultrapure dialysis fluid contains less than 0.1 CFU/mL and 0.03 EU/mL and can be prepared by ultrafiltration of standard‐quality dialysis fluid. Today, the use of ultrapure dialysis fluid is widely recommended based on our awareness of potential transfer of bacterial products across dialysis membranes. Early observations associated improved fluid quality with reduced incidence of the carpal tunnel syndrome, but provided no proof of mechanism. Recent clinical studies in hemodialysis patients have shown that the introduction of ultrapure dialysis fluid brings about significant improvements in a number of inflammation‐related parameters. Levels of C‐reactive protein and IL‐6 are reduced, anemia management is achieved using less EPO or reaching higher hemoglobin levels, nutritional indices are improved, and β 2 ‐microglobulin levels have been observed to decline, when ultrapure dialysis fluid is used in comparison with standard‐quality fluid. In addition, some studies have documented reduced levels of advanced glycation end products and delayed decline of residual renal function in patients using ultrapure dialysis fluid. Although further evidence is needed before we can assess the long‐term benefits associated with improved fluid quality, there should be sufficient data available today to support our efforts toward gradual improvement of the microbiological quality of dialysis fluid.
