Dialysis modality and quality of life: more answers yet more questions.

Abstract

Persons with end-stage kidney disease treated with dialysis experience distressing reductions in quality of life and increased mortality. Few large, randomized trials in nephrology have reported on health-related quality of life. Rose et al. report beneficial effects of high-volume hemodiafiltration versus high-flux hemodialysis on secondary end points of health-related quality of life in the CONVINCE trial (Comparison of High Dose Hemodiafiltration with High Flux Hemodialysis Trial). These results raise questions regarding hemodiafiltration as a potential modality to preserve health-related quality of life in end-stage kidney disease.
