In order to evaluate the grounds for the reduced plasmatic concentration of Zn in elderly patients undergoing hemodialysis, we studied 9 elderly patients (age > 53 years) suffering from chronic uremia, who underwent extracorporeal dialysis 3 times a week. In these patients we evaluated the nutritional status, the plasmatic concentration of Zn (before and after dialysis), the intake of the phosphorus-chelating agents and the protein catabolic rate (PCR). Our data show that, in dialysed patients, the values of Zn (68.9 ± 19.3 mcg/dl) are lower than the normal values reported for that age. The reduced plasmatic levels of Zn should not be ascribed to a lower nutritional intake, taking into account the good nutritional status and the normal values of PCR, but to a different compartmentalization of this micronutrient and to a reduced enteral absorption determined by the intake of the phosphorus-chelating agents.
