Disturbances of trace element concentrations in plasma of patients with chronic renal failure.
Plasma concentrations of 6 essential trace elements were measured in undialyzed and hemodialyzed patients with chronic renal failure (CRF) and in healthy volunteers by tube-excited X-ray fluorescence analysis and atomic absorption analysis. The influences of hemodialysis on plasma concentrations of Al, Zn, Cu and Br were also studied. High plasma concentrations of Al and Cu and low concentrations of plasma Zn were found in nondialyzed patients with CRF. Plasma concentrations of Al and Cu increased and Zn and Br decreased in the hemodialyzed patients with CRF. An elevated concentration of plasma Al may be primarily caused by permeation from dialysate across the dialyzer membrane. The use of water produced by reverse osmosis will prevent the elevation of plasma Al concentration in patients with CRF.
