Commentary for 'effect of frequent hemodialysis on residual kidney function': Frequent Hemodialysis Network (FHN) Trials

Abstract

This post hoc analysis of the recently reported Frequent Hemodialysis Network Trials suggests that frequent nocturnal treatment, unlike frequent daily treatment, may be associated with more rapid loss of residual kidney function than conventional hemodialysis. Differences in blood pressure control, among other factors, may be implicated. The study invites reflection on our current concepts of the importance of preserving residual kidney function and on the indications for frequent treatments, particularly nocturnal.
