Abstract

Advanced glycation endproducts (AGEs) accumulate in uraemia as a consequence of diminished clearance of low molecular weight forms which retain their reactivity and may subsequently combine with circulating and tissue macromolecules. Successful renal transplantation is the only form of renal replacement therapy which effectively clears these circulating AGEs; both haemodialysis and peritoneal dialysis are comparatively ineffective although high-flux haemodialysis confers some benefits. De novo AGE formation may be accelerated in uraemia due to carbonyl and oxidative stress leading to further accumulation. The consequences for the patient with chronic renal failure may be acceleration of vascular disease, renal failure progression and dialysis-related amyloidosis. Accelerated peritoneal AGE formation as a consequence of treatment with peritoneal dialysis fluids may be detrimental to peritoneal membrane function but does not appear to contribute to systemic elevation of AGEs.
