Vitamin, mineral and trace element supplementation of children on chronic peritoneal dialysis

This study was initiated to assess the dietary intakes of particular vitamins (A, D, B,2) and trace minerals (iron, zinc and copper) which we do not routinely supplement in children undergoing chronic peritoneal dialysis. Eight children were studied and all were receiving protein and energy supplements. The mean dietary intakes of the above micronutrients with the exception of Vitamins A and B₁₂ were below UK RDA values for chronological age but all were comparable to age and sex matched controls. No clinical deficiencies were detected in the short term but patients on long-term dialysis may require a more comprehensive vitamin and trace mineral supplement.
