The aim of this double-blind randomized clinical trial is to determine the effects of isoflavones on serum concentrations of fructoseamine and advanced glycated end products in peritoneal dialysis patients. Forty-four patients from shafa clinic will randomly assign to either isoflavone or placebo group. The patients in isoflavone group will receive 100 mg soy isoflavone (as 2 capsules) daily for 8 weeks, while the placebo group will receive identical placebo. At the baseline and the end of the study,7 ml blood will be collected from each patient after a 12-14-hours fasting and serum concentrations of fructoseamine, carboxymethyl lysine, pentosidine, glucose will be measured. Furthermore, blood pressure measurements will be performed twice with a ten-minute interval between testing
