Sažetak
Introduction: It is well established that nutritional status is an important factor affecting the outcome and recovery from disease or injury. Assessment of nutritional status is an integral part of care for patients with chronic kidney disease, especially for those treated with dialysis procedures. According to available literature, 18%-80% of patients on dialysis have some form of nutritional deficiency. Furthermore, in patients treated with dialysis procedures there is a rule called ‘reverse epidemiology’, according which patients with better nutritional status have better survival rate. Therefore, nutritional assessment should detect malnutrition and rate the overall nutritional status of each patient through clinical data categories: medical history, physical examination, nutrition physical examination, psychosocial history, demographics, physical activity, and current medical/surgical issues. Consequently, the main aim of our study was to analyze the nutritional status of our patients treated with hemodialysis procedures. Another aim was to analyze the applicability of measuring skinfold by caliper as a method of nutritional status assessment. Subjects and Methods: During a six-month period, we analyzed 129 patients (57.4% of men and 42.6% of women), mean age 68.1±12.4 years, treated with hemodialysis procedures (24.8% of patients were treated with online hemodiafiltration and 75.2% with standard, conventional hemodialysis) as the method of choice of renal replacement therapy (RRT) for more than 6 months. All patients were dialyzed three times a week for four hours on biocompatible synthetic membranes. The patients treated with online hemodiafiltration were dialyzed on high-flux helixone membranes, while those treated with standard, conventional hemodialysis were dialyzed on polysulfone membranes and helixone low-flux membranes. The mean time of RRT was 71.2±56.7 months. During the study period, in each patient we followed medical history, and clinical and laboratory parameters of nutritional status at 3 and 6 months. To assess the nutritional status, we used dry weight (DW), body mass index (BMI), skinfold caliper measurement (result is correlated with total body fat, FAT), and common laboratory indicators of nutritional status (serum albumin and cholesterol). Results: Analyzing the efficiency of skinfold thickness measurement with caliper, we found that the FAT obtained by caliper showed a statistically significant positive correlation with clinical indicators of nutritional status, and with BMI (r=0.364, p<0.0001), DW (r=0.206, p=0.005) and volume of muscle circumference (r=0.399, p<0.0001). Also, FAT showed statistically significant positive correlation with laboratory indicators of nutritional status, including serum albumin (r=0.299, p=0.01) and cholesterol (r=0.225, p=0.002). There was no statistically significant correlation between the duration of RRT and FAT (p=NS). Conclusion: In clinical practice, as well as for regular evaluation of nutritional status, it is important that the method we used proved efficient, precise, relatively fast and posing less economic burden. From our experience, the measurement of skinfold with caliper is an applicable, relatively quick and inexpensive method for regular assessment of nutritional status in patients treated with hemodialysis procedures. Therefore, all patients treated with RRT should undergo nutritional screening and expert help should be available from dietitians or nutritional support teams in order to identify this problem properly in its early stage and to reduce its high prevalence.
