Malnutrition-Inflammation-Atherosclerosis (Mia) Syndrome in Hemodialysis Patients

Abstract

Background: Mortality resulting from cardiovascular disease in patients with end-stage renal disease (ESRD) is high. In this study we study characteristics of the malnutrition, inflammation, atherosclerosis (MIA) syndrome; relationship between MIA syndrome and the cardiovascular events in hemodialysis patients. Subjects and methods: A total of 61 hemodialysis patients were enrolled. Inflammatory marker (hs CRP) and nutritional parameters (albumin, prealbumin, BMI) were determined. Carotid atherosclerosis was investigated by ultrasonographically evaluated carotid intima-media thickness (cIMT). Results: -The characteristics of the malnutrition, inflammation, atherosclerosis(MIA) syndrome in in peritoneal dialysis patients: + MIA2-3 group had an average age lower than MIA0 group + MIA2-3 group had lower albumin levels and BMI than MIA0 group. + The prevalence of malnutrition (50.8%), inflammation (27.9%), and atherosclerosis (52.5%); 24 (39.3%) of the patients had one risk factor; 22 (36.1%) of the patients had two risk factors; 4 (6.6%) of the patients had all three risk factors. No signs of either malnutrition, inflammation or atherosclerosis were seen in 11 (18.0%) of patients. Note that a considerable number of patients with malnutrition (23/31 patients) had signs of inflammation or atherosclerosis or both; 12/32 patients with atherosclerosis had signs of inflammation or malnutrition or both. - The relationship between MIA syndrome and the cardiovascular events in peritoneal dialysis patients: We have found the relationship between component M (malnutrition) and the cardiovascular events in syndrome MIA (HR: 4.23 95% CI: 1.89-9.50). Our study suggests that high risk cardiovascular events in patients with 2 or more elements in MIA syndrome (HR: 2.40 95% CI: 1.16-5.00). Conclusion: We had demonstrated an association between malnutrition, inflammation and atherosclerosis; component M (malnutrition) and the cardiovascular events in hemodialysis patients; high risk cardiovascular events in patients with 2 or more elements in MIA syndrome.
