    Abstract:
    AIM: To assess the rate and clinical significance of impaired nutritional status and impact of low-protein diet on inhibition of renal insufficiency in patients of stage III-IV chronic disease of the kidneys (CDK). MATERIAL AND METHODS: A total of 200 patients with CDK stage III-IV were randomized into three groups: group 1 consisted of 123 patients with chronic glomerulonephritis (73 with stage III and 50 with stage 1V), group 2--45 patients with systemic diseases (30 with stage III and 15 with stage IV), group 3 (a comparison group)--32 patients with CGN (17 with stage 111 and 15 with stage IV). Patients of groups 1 and 2 received low-protein diet (0.6 g protein kg/day) balanced by either high-calorie mix containing protein SUPRO 760 or ketosteril for 24-48 months. The nutritional status was studied by anthropometric data, absolute number of lymphocytes, levels of blood albumin and transferring, intake of protein, food calorie value according to 3-day diaries. RESULTS: Among 200 patients impaired nutritional status was detected in 22 (11.0%) patients. More than half of them had glomerulonephritis in systemic diseases (SLE, systemic vasculitis). Only in patients with systemic diseases nutritional disorders manifested at stage III. These disorders grew with progression of renal insufficiency and were detected primarily in patients with stage IV CDK. Patients with CGN on low-protein diet for a year and longer demonstrated slowing of the fall of the glomerular filtration rate (GFR). CONCLUSION: Early (predialysis) use of low-protein diet balanced by addition of amino- and keto-acids and high-energy nutritional mixes has a positive influence on nutritional status of patients with chronic renal insufficiency and can inhibit GFR lowering.
