BACKGROUND: Low serum @entity1372 is uncommon in @entity298 ( @entity298 ), which is surprising in view of the important role of normal kidney function to regulate water and @entity1372 balance. METHODS: We report 2 cases of persistent @entity2753 with balance studies in Case 1. We performed measurements of dialysate @entity1372 and volume output over 24 hours in a group of chronic @entity298 @entity1 . RESULTS: The low serum @entity1372 concentration did not vary too much with overall fluid removal via dialysis in @entity1 1, mainly because large quantities of @entity1372 were removed in the dialysate. In the 24-hour studies, a significant relationship was found between net daily @entity298 @entity1372 removal and net daily dialysate volume removed (r = 0.65). There was no relationship between net daily @entity298 @entity1372 removal and serum @entity1372 concentration. There was a linear direct correlation between serum and dialysate @entity1372 concentration (r = 0.8) as shown by others previously. CONCLUSIONS: These results suggest that the main determinant of @entity298 @entity1372 loss is net dialysate ultrafiltration volume. Water loss via dialysis is necessarily associated with @entity1372 loss. In order to maintain a normal serum @entity1372 concentration salt intake must be proportional to the water loss induced by dialysis. The stimuli that allow dialysis @entity1 to maintain this delicate balance between water and salt intake are of considerable interest but remain undetermined.
