title: Evaluation of 25-hydroxyvitamin D and vitamin D binding protein losses in thirteen children on continuous ambulatory peritoneal dialysis.
abstract: Thirteen children, 6 females, 7 males, aged 2 to 13 years were studied. At the time of study they were on continuous ambulatory peritoneal dialysis (CAPD) for 1 to 22 months. 25-(OH)D loss in daily dialysate fluids represented 2 to 22 micrograms/day. A significant correlation was found between 25-(OH)D plasma concentration and 25-(OH)D dialysate concentration. 25-(OH)D clearance was correlated to 25-(OH)D binding protein clearance (p less than 0.001). These findings of important 25-(OH)D losses in the dialysate fluid of children on CAPD demonstrate the necessity of carefully adapted vitamin D intakes with such a treatment.
