Serum Chromium Levels Are Higher in Peritoneal Dialysis than in Hemodialysis Patients.

An elevation in serum chromium levels in individuals treated with renal replacement therapy has been previously described, but chromium levels have not been systematically studied in patients treated with different dialysis modalities. The aim of this study was to compare serum chromium levels in patients treated with chronic peritoneal dialysis (PD) and hemodialysis (HD).We studied 169 chronic dialysis patients in a single medical center, of which 148 were treated with HD and 21 with PD.

N-acetylcysteine improves residual renal function in peritoneal dialysis patients: a pilot study.

Background: Preservation of peritoneal membrane function and residual renal function is important for the optimal care of peritoneal dialysis patients. N-Acetylcysteine may ameliorate oxidative stress, which is thought to be involved in peritoneal membrane dysfunction. In addition, N-acetylcysteine may have a positive effect on renal function in the setting of nephrotoxic contrast media administration.
