Abstract

Background and AimsWe 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.MethodsWe 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, χ2, Fisher exact test, linear or logistic regression models, using SPSS v.16.0. p values <0.05 were considered as significant.ResultsThere were 66 (49.3%) females; 39 (29.1%) had CKD stages 2-4 (predialysis), 42 (31.3%) on hemodialysis (HD) and 53 (39.6%) on automated peritoneal dialysis (PD). Time from diagnosis was 26 months. Significant differences were observed in mean, systolic and diastolic blood pressure, C-peptide, triglycerides, and HDL-cholesterol as well as PON1/HDL-cholesterol ratio and SOD.ConclusionsThis study demonstrates that PON1 and SOD may be predictors for the presence of MetS in pediatric patients under treatment with peritoneal dialysis. The positive correlation observed in PON1/HDL-cholesterol ratio may reflect the protector effect of HDL-cholesterol in patients with CKD according with the modality of treatment.
