Dietary sodium and clinical outcome in hemodialysis: where do we stand and what is next?

The association of dietary sodium and outcome is widely studied in the general population, but less is known in hemodialysis patients. The evidence supporting daily dietary sodium intake of 2g on hemodialysis is not strong. Mc Causland et al. found that higher dietary sodium intake was marginally associated with a higher ultrafiltration requirement and mortality, but not with blood pressure. Well-designed clinical trials are needed to examine the association of dietary sodium modification and outcomes in hemodialysis patients
