NUTRITIONAL DISTURBANCES IN PATIENTS WITH CHRONIC KIDNEY DISEAS STAGE WHO ARE TREATED BY PERITONEAL DIALYSIS AND ITS RELATIONSHIPS WITH HYDRATION STATUS

Abstract
The aim of the study was to estimate the nutritional status of patients with chronic kidney disease who are treated by CAPD, the prevalence of its disorders according to functional methods. To study the relationship between nutritional status and hydration. Materials and Methods: During the observational one-stage study, 105 patients with CKD 5D stage who were treated by CAPD were included. To assess the NS, serum albumin and body mass index were determined, functional methods were used, namely, SGA and dietary diary analysis. The status of hydration was assessed by clinical examination and bioimpedance analysis. The study was carried out in two stages. At the first, the definition of laboratory and functional indicators of the National Assembly, assessment of the balance of water sectors was carried out. At the second stage, for further analysis, the patients were divided into four groups according to the condition of the NS, determined on the basis of the SGA: the first group (n = 54) consisted of patients without disturbance of nutrition, the second (n = 27) with mild disruption of nutrition, the third (n = 13) — with an average degree, and the fourth (n = 11) - with a severe degree of malnutrition. Results: Weight loss and subcutaneous fat mass for the past 6 months were detected in 43.8% and 37.14% of patients, respectively. Gastrointestinal disorders and loss of muscle mass were detected in 58.1% and 74.3% of patients, respectively. According to the SGA, nutritional disorders were detected in 51 (48.6%) patients. An easy degree of malnutrition was diagnosed in 25.71% of patients, medium and severe — in 12.38% and 10.48% of patients, respectively. For compare of the data obtained from the survey on the composition of water sectors with reference values allows one to assert the presence of hyperhydration in the examined population. A statistically significant difference is achieved by the volume of extracellular fluid, the volume of circulating blood and plasma. These parameters significantly increase depending on the degree of disturbance of the NS (p
