Originally a definition of water quality for the semiconductor industry, the term ‘ultrapure’ has been adopted by the dialysis community. The discussion has developed from basic definitions and methods for quantification to clinical benefits and recommendations for implementation. Today, ultrapure dialysis fluid is subject to the demands of evidence-based medicine or at least evidence-based cos...
In patients with renal disease undergoing cardiovascular surgery, perioperative management continues to be a challenge. Traditional answers have turned into new questions with the introduction of new agents and the redesign of old techniques. For ARF prevention, early recognition of pending deleterious compensatory changes is critical. Theoretically, therapeutic intervention designed to prevent...
The objective of this study was to determine intradialytic blood levels of nitric oxide (NO), in patients undergoing chronic haemodialysis. This was done by detection of nitrosylhaemoglobin by a sensitive technique of spin trap electron paramagnetic resonance at 0, 5, 15, 60, 180 and 240 min of a 4-h standard bicarbonate dialysis, using the same dose (6000 U) of heparin and different dialysis m...
Anaemia secondary to chronic kidney disease is a complex syndrome. Adequate dialysis can contribute to its correction by removing small, and possibly middle/large molecules, that may inhibit erythropoiesis. A clear relationship between higher haemoglobin or haematocrit levels, lower recombinant human erythropoietin (epoetin) dose and increase in dialysis dose has been reported in a number of pr...
Background: The risk of atherosclerosis and cancer is high in hemodialysis (HD) patients. There is evidence that HD causes oxidative stress. However, the causative factors of oxidative stress are unknown. It has been suggested that HD imposes an additional oxidative stress on patients with chronic renal failure by activation of granulocytes on dialyzer membranes resulting in an imbalance betwee...
Background. A number of studies suggested that the type of dialysis membrane is associated with differences in long-term outcome of patients undergoing haemodialysis, both in terms of morbidity and mortality. In the majority of dialysis units, synthetic membranes are being used. However, no studies are available so far for comparison between different biocompatible membranes. Therefore, we stud...
In the last 10 years, the concept of biocompatibility as applied to haemodialysis membranes has gained a general clinical acceptance in light of the knowledge that the clinical expression of b2-microglobulin (b2m) amyloidosis found in long-term haemodialyzed patients was governed by the characteristics of dialysis membranes. Highly permeable and biocompatible synthetic membranes interfere with ...
