[Determination of the plasma aluminum concentration of hemodialysis patients]

Plasma aluminium concentration was followed up in 28 patients with chronic renal insufficiency, treated with hemodialysis in the course of four years. Increased value of plasma aluminium was established as compared with a control group of healthy subjects, not observing any clinical signs of dialysis dementia. Slight increase of plasma aluminium at the end of the dialysis, was observed when the dialysis solution was prepared with non-purified potable water. When purified water, by reverse osmosis, was used the plasma aluminium concentration of the patients was not changed during the dialysis (the differences observed were not statistically significant). That fact provided grounds the authors to admit that the reason for the plasma aluminium increase during dialysis was the aluminium found in the dialysis solution, which necessitates water meeting the standard requirements for the allowable aluminium content, to be used for the needs of hemodialysis.
