Peritoneal fibrosis is one of the major causes of technical failure in patients on peritoneal dialysis (PD) for long period of time. Although the exact mechanisms of peritoneal damage during PD still remain unclear, generation of reactive oxygen species may be responsible for progressive membrane dysfunction. N-acetylcysteine (NAC)is a powerful antioxidant shown to protect peritoneal fibrosis in peritoneal dialysis animal model. In this study the researchers investigated the hypothesis that NAC protect peritoneal membrane damage.

Primary Outcome Measures:
  • Peritoneal membrane function [ Time Frame: 6 months ]
    Changes in peritoneal membrane function (Δ D/Pcreatinine, ΔD/Purea) with peritoneal equilibrium test

Secondary Outcome Measures:
  • Oxydative stress status [ Time Frame: 6 months ]
    Measurement of oxydative stress status with plasma and RBC (GSH/GSSG, 8-OHdG)

  • Mesothelial cell transformation (Epithelial to Mesenchymal Transition) [ Time Frame: 6 month ]
    Morphology was analysed with peritoneal dialysate isolated mesothelial cell

  • Residual renal function [ Time Frame: 6 month ]
    Changes in residual renal function (ΔKt/Vurea, ΔeGFR)

  • Peritoneal membrane function [ Time Frame: 2 months ]
    Changes in peritoneal membrane function (Δ D/Pcreatinine, ΔD/Purea) with peritoneal equilibrium test

Estimated Study Completion Date: December 2011
Estimated Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Control
Age and sex matched peritoneal dialysis patients
Experimental: N-acetylcysteine
N-acetylcysteine in stable peritoneal dialysis patients
Drug: N-acetylcysteine
N-acetylcysteine (200 mg/capsule) 1200 mg/day (600 mg bid) for 6 months

Inclusion Criteria:

  • Maintenance peritoneal dialysis at least 3 months
  • Patients who are able and willing to understand, sign and date an informed consent document, and authorize access to protected health information

Exclusion Criteria:

  • Episode of peritonitis at least 3 months
