Objective: To evaluate oxidative stress in uremia and dialysis and chromogranin A, a stress hormone that could be related to oxidative processes. Methods: Plasma oxidative stress biomarkers (-SH, 8-OHdG, and ox-LDL) and chromogranin A were measured in 89 outpatients (21 uremic patients, 17 in peritoneal dialysis, and 51 in haemodialysis), and in 18 subjects with normal renal function. Results: -SH groups were significantly reduced in heamodialysis, peritoneal, and uremic patients as compared with the control group (p=0.01), while 8-OHdG was increased (p<0.01). No differences were observed for ox-LDL. Chromogranin A was increased in uremic, peritoneal and haemodialysis patients (p<0.01), showing a positive correlation to 8-OHdG (p<0.01). Conclusion: Oxidative stress biomarkers and chromogranin A levels differ between control subjects when compared to both uremic and dialysis patients. No differences were observed between uremic and dialysis patients, suggesting that uremia is the major source of the increase in oxidative stress and CgA levels in patients with end stage renal disease. © 2010.

Abstract

Objective: To evaluate oxidative stress in uremia and dialysis and chromogranin A, a stress hormone that could be related to oxidative processes. Methods: Plasma oxidative stress biomarkers (-SH, 8-OHdG, and ox-LDL) and chromogranin A were measured in 89 outpatients (21 uremic patients, 17 in peritoneal dialysis, and 51 in haemodialysis), and in 18 subjects with normal renal function. Results: -SH groups were significantly reduced in heamodialysis, peritoneal, and uremic patients as compared with the control group (p=0.01), while 8-OHdG was increased (p<0.01). No differences were observed for ox-LDL. Chromogranin A was increased in uremic, peritoneal and haemodialysis patients (p<0.01), showing a positive correlation to 8-OHdG (p<0.01). Conclusion: Oxidative stress biomarkers and chromogranin A levels differ between control subjects when compared to both uremic and dialysis patients. No differences were observed between uremic and dialysis patients, suggesting that uremia is the major source of the increase in oxidative stress and CgA levels in patients with end stage renal disease. © 2010.
