#1530 Studying parenteral nutrition in patients with dialysis stage chronic kidney disease

Abstract

Abstract Background and Aims Hemodialysis is associated with high rates of morbidity and mortality, as well as poor quality of life. Changes in nutritional status and loss of protein and energy are important indicators of these risks. Maintaining optimal nutritional status in hemodialysis patients is an important but sometimes overlooked aspect of treatment. In some cases, intradialytic parenteral nutrition is possible, but lack of knowledge about the practical aspects of administration is rarely discussed. The purpose of our study was to study the age-related characteristics of the nutritional status in patients with CKD of the dialysis stages who are on parenteral nutrition. Method The study included 40 patients with stage C5 CKD. Glomerular filtration rate (eGFR) was estimated using the CKD-EPI formula (2011) [11]. Anthropometric data were studied: height, weight, body mass index (BMI), mid-thigh circumference and mid-upper arm circumference, as well as laboratory data: urea, creatinine, electrolytes, albumin, total protein, hemoglobin. All patients underwent instrumental research methods: ECG, EchoCG. The patients were divided into 2 groups – with and without PEM. Statistical data processing was carried out according to standard methods using a computer program package. Results Total body water (TBW) (P = 0.026) and triceps skinfold thickness (P < 0.05) were higher in the hemodialysis group. BMI and other anthropometric parameters showed no significant differences between the two groups. Total caloric intake (P < 0.05) and total cholesterol (P < 0.05) were higher in patients with PEM. Intake of other nutrients, including proteins, lipids, microelements and vitamins, did not show significant differences between the two groups. Only 24% of patients were malnourished. Triglyceride levels were higher in non-malnourished patients, but HDL levels were higher in malnourished patients. Some anthropometric indicators were significantly higher in patients not suffering from PEM. It is worth noting that malnourished patients consumed more calories and nutrients, including proteins, plant lipids, animal lipids and carbohydrates. Conclusion Compared with malnutrition patients and non-malnutrition patients, several anthropometric parameters, including subiliac skinfold thickness and MAC, were significantly lower in the malnutrition group. These values can be measured using simple methods and are used as a useful method for assessing malnutrition. Interestingly, patients with malnutrition and lower BMI albumin actually consumed more calories and nutrients from food. This means that malnutrition in dialysis patients is not simply caused by low food intake.
