We undertook this study to evaluate the relationship between PON1, SOD and metabolic syndrome (MetS) in pediatric patients undergoing peritoneal dialysis, hemodialysis and patients in early stages of CKD. We carried out an analytical cross-sectional study of 134 children 6-17 years old. We registered anthropometric variables, vital signs, basic biochemical parameters, intact PTH (iPTH), high sensitivity CRP (hs-CRP), paraoxonase-1; SOD; PON1/HDL-cholesterol and homocysteine. For statistical analyses we used t test, Mann Whitney U test, χ(2), Fisher exact test, linear or logistic regression models, using SPSS v.16.0. p values
