[Trace element changes in the serum of dialysis patients].

In 60 patients of our dialysis program lowered zinc levels as well as increased chromium levels were observed in serum. These alterations were compared to the parameters of glucose and lipid metabolism. Furthermore, a negative correlation of chromium and HDL-cholesterol levels could be observed. Our results could not be confirmed in patients with renal insufficiency under conservative treatment. These findings make it apparent that a substitution of the dialysis fluid with trace elements has to be discussed.
