Malnutrition-Inflammation Score: A Valid Tool to Assess Nutritional Status in Patient with End-stage Renal Disease

Nutritional assessment is a basic and necessary process in the nutritional management of dialysis patients. Malnutrition is a prevalent complication in patients on maintenance hemodialysis (HD). The study aimed to evaluate its relationship with the duration of dialysis, demographic and socioeconomic profile of HD patients, and to assess malnutrition inflammation score (MIS) in HD patients. In this descriptive-analytical study, 153 HD patients were selected with random sampling. All the patients were interviewed and the MIS of the patients was recorded. Evaluate the relationship of malnutrition with the duration of dialysis, demographic and socioeconomic profile of HD patients, and to assess MIS in HD patients. Patients were followed up for 3 months. Data were analyzed with Chi-square and t-tests and Pearson correlation coefficient. A total of 153 patients were studied, 53 (34.64%) patients had good nutritional status and 100 (65.35%) patients had malnutrition. The mean of patients MIS score was 10.71 ± 5.14. Malnutrition rates in males and females were not significantly different. There was a positive and significant relationship between age and MIS score (P = 0.035). There was also a significant correlation between the level of education and MIS score (P = 0.042). The mean dialysis duration was 25.52 ± 2 6.27 months. There was a significant difference in the duration of dialysis in mild to severely malnourished patients (P = 0.002). A significant correlation between MIS score and the serum calcium and serum iron results (r = 0.402). The rise in serum prealbumin level was significantly greater at 3 months. MIS score is the best tool to assess nutritional status in patients with ESRD undergoing HD, because it can recognize various degrees of malnutrition that may remain undetected by a single laboratory assessment. The correlation between MIS score and age and dialysis period was significant.
