Abstract: Background: Malnutrition-Inflammation Score (MIS) has been proposed as a new quantitative system for assessment of malnutrition and inflammation, which are common important risk factors for increased morbidity and mortality in maintenance hemodialysis (MHD) patients. Objective: To determine the MIS and related it to the presence of atherosclerosis, and the morbidity and mortality rate. Material and Method: The inflammatory and nutritional status in 100 MHD patients was evaluated by serum high-sensitivity C-reactive protein (hs-CRP), Subjective Global Assessment (SGA), and MIS. Atherosclerosis was defined by a history of cardiovascular disease or presence of carotid plaque by B-mode ultrasonography. Twelve-month prospective hospitalization and mortality rates were recorded. Results: The MIS score was significantly higher in patients with atherosclerosis (5.5 ± 2.3 vs. 3.0 ± 1.7, p = 0.003) and modestly correlated with serum ferritin level (r = 0.304, p = 0.03), but did not correlated with hs-CRP. The SGA was not associated with hs-CRP level and atherosclerosis. Over a 12-month follow-up period, 4 patients died and 28 were hospitalized at least once. Compared to the survivor group, MIS in the deceased group was significantly higher (8.0 ± 1.4 vs. 5.1 ± 2.3, p = 0.01) while SGA, hs-CRP and other biochemical markers were not significantly different. The Receiver Operating Characteristics Curves for the prediction of 1-year mortality from the MIS score identified the optimal cut-off value of 7.5 with sensitivity of 75% and specificity of 88%. There was no association between MIS or SGA and hospitalization. Conclusion: MIS is a useful tool for the assessment of malnutrition and inflammatory status. It is superior to the conventional SGA as a predictor of short-term outcome in MHD patients.
