Abstract
To our knowledge, there are no studies on advanced chronic kidney disease (CKD) analysing the impact of ageing on serum concentrations of uraemic toxins while adjusting for renal function. Knowledge of this feature, however, could influence prognostic assessment and therapeutic decision-making, e.g. about when to start dialysis or how intensive it should be. Indeed, the slowing down of metabolism with age may result in lower uraemic toxin concentrations, hence reducing their toxic effects. In this case, a later start of dialysis or less intensive dialysis may become justified in an already fragile population that might enjoy a better quality of life...
