Design outcomes

Primary

MeasureTime frame
The primary endpoint of this study is the antioxidant effect by oral L-cysteine on peritoneal dialysis patients. Blood reduced glutathione/oxidized glutathione ratio, serum MDA-LDL and plasma homocysteine are measured after six-month oral L-cysteine treatment.

Secondary

MeasureTime frame
The secondary end point of this study is the preservation of residual renal function and peritoneal function by oral L-cysteine on peritoneal dialysis patients. Beta2-microglobulin and Cystatin C levels are measured after six-month oral L-cysteine treatment as residual renal function. Ay the same time, weekly urea Kt/V and creatinine clearance are assessed as peritoneal dialysis function.
