Vitamins and continuous ambulatory peritoneal dialysis (CAPD)

The authors assessed vitamin A, and its protein carriers vitamins C and E in serum and dialysis fluid of 10 patients with chronic renal failure during 6–12 months of continuous ambulatory peritoneal dialysis.Vitamin A and its protein carriers and serum vitamin E were elevated throughout the long-term investigation of continuous ambulatory peritoneal dialysis despite the fact that vitamin A and its protein carriers have a relatively great peritoneal transfer and loss into the dialysis fluid. The oral dose of 200 mg of vitamin C per day, despite the great peritoneal transfer and loss into the dialysis fluid, prevented the development of hypovitaminosis C. Assessment of vitamins B₁, B₂ and B₆ revealed that the supplementation with these vitamins is adequate for patients during continuous ambulatory peritoneal dialysis.
