[Analysis of the food rations of predialysis patients with chronic renal failure receiving essential amino acid ketoanalogues]. / Analiza racji pokarmowych osób z przewlekla niewydolnoscia nerek leczonych zachowawczo z zastosowaniem ketoanalogów aminokwasów egzogennych.

The aim of the study was to analyse daily food rations of patients with chronic renal failure (CRF) receiving a supplement containing essential amino acid ketoanalogues (EAAK). The study was carried out on 60 patients with CRF of different etiology. During the progression of CRF, decline of consumption of products being the source of protein and limitation of consumption of products high in energy were observed. This can lead to protein-energy malnutrition. The results of the research emphasize the necessity of providing patients with CRF constant dietician care that would assure possibility to adjust diet to individual needs of every patient as well as to modify it, if necessary, and that would have significant influence on prolongation of the phase of predialysis treatment as well as on better preparation to dialysis.

Analysis of the intake of protein and energy by predialysis patients with chronic renal failure receiving essential amino acid ketoanologues.

The aim of the study was to evaluate daily dietary intake of energy and protein by predialysis patients with chronic renal failure (CRF) receiving a supplement containing essential amino acid ketoanalogues. The study was carried out on 60 patients with CRF of different etiology. Low intake of energy (88% of tested patients) and animal protein (23% of tested patients) were observed, whereas total protein level was too high (33% of tested patients). As a consequence, the analyzed diets were not properly balanced. Our data strongly suggest that constant dietician care is essential to correct protein and energy intake in patients with CRF and can protect them against malnutrition and progression of CFR.
