Purpose: Cardiovascular diseases are the main causes of morbidity and mortality in children with end-stage renal disease and the relationships among several relevant potential biomarkers were investigated in pediatric peritoneal dialysis patients.Methods: Serum homocysteine, von Willebrand factor (vWF), apolipoproteins A and B, lipoprotein-a, high sensitive-CRP, hemoglobin, phosphorus and parathyroid hormone (PTH) levels, systolic (SBP) and diastolic (DBP) blood pressure, carotid intima-media thickness (cIMT) and left ventricular mass index (LVMI) were measured in 21 pediatric peritoneal dialysis patients and control subjects. Results: All risk factors were higher in patients than controls. LVMI values were negatively correlated with hemoglobin and positively correlated with PTH and phosphorus levels (p=0.007, r= - 0.573; p=0.013, r= 0.532 and p=0.035, r= 0.461, respectively). cIMT was negatively associated with serum albumin and positively correlated with vWF levels and with SBP and DBP (p=0.006, r= - 0.578; p=0.039, r= 0.453; p=0.02, r= 0.503; p=0.024, r= 0.491, respectively). Robust regression analyses showed that hemoglobin was an independent predictor of LVMI and serum albumin was an independent predictor of cIMT. Conclusion: Only uremia-related factors were independent risk factors for predicting LVMI and cIMT. Hemoglobin level may be a critical factor in the development of left ventricular hypertrophy; therefore, effective treatment of anemia is crucial. Low serum albumin and high hsCRP and vWF levels, and their correlations with cIMT, indicate these patients could be at risk of developing malnutrition–inflammation–atherosclerosis syndrome and suggest that serum albumin and vWF levels may be useful markers for early detection of vascular damage.
