[Nutrition problems in kidney diseases].

The practice of dietetic therapy is unusual today for patients suffering from renal failure without hypertension and reduction of glomerular filtration rate. Specific treatment is needed, however, for arterial hypertension, uremia, calculus and uralith disease. Experiments in rats showed, that a lot of uremic symptoms following poorly functioning kidneys are partly at least caused by disturbances in amino acid metabolism. Uremia patients with dysfunctioning plasma protein metabolism (transferrin, complement, cholinesterase, prealbumin and retinolbinding protein) need oral, respectively parenteral substitution of essential amino acids. This substitution is very important under catabolic stress conditions in uremic syndrome with and without vividialysis treatment.
