Abstract

Chronic peritoneal dialysis (PD) can result in several peritoneal alterations of varying degree, which lead to progressive reduction in dialytic efficacy. Although its pathogenesis has not been clarified yet, it has been proposed that high glucose induced oxidative stress generation within the peritoneal membrane plays an important role in leading to membrane alterations. The aim of this study was to investigate the effect of oxidative stress inhibition on peritoneal alterations induced by hypertonic PD solutions in rats. The rats were divided into three groups receiving no treatment (the control group), hypertonic PD solution intraperitoneally (ip) only (the hypertonic dextrose group) and hypertonic PD solution ip plus trimetazidine (TMZ) orally (TMZ group). After 4 weeks, a one-hour peritoneal equilibration test (PET) was performed. Dialysate-to-plasma urea ratio (D/P urea), glucose reabsorption (D(1)/D(0) glucose), ultrafiltration volume (UF) and the level of dialysate protein were determined. The levels of malondialdehyde (MDA), vascular endothelial growth factor (VEGF) and the activity of glutathione peroxidase (GPx) were investigated in the peritoneal tissue lysates. The peritoneal membrane was evaluated histologically by...Continue Reading
