Malnutrition-inflammation score and endothelial dysfunction in hemodialysis patients.
OBJECTIVE
The aim of this study was to find out the relationship between Malnutrition-Inflammation score (MIS) and the endothelial function parameters, including measurements of flow-mediated vasodilatation (FMD) in the brachial artery and serum vascular cell adhesion molecule-1 (VCAM-1). Furthermore, predictors of FMD were also assessed.


METHODS
A total of 70 anuric hemodialysis patients were enrolled in this cross-sectional study. Measurements of FMD, serum VCAM-1, oxidized low density lipoprotein cholesterol (oxLDL) were done before the mid-week dialysis session from all participants at the time of MIS calculation. Patients were divided into 3 groups according to MIS (the MIS was ≤4 in group I, 4< and ≤7 in group II, and >7 in group III) and compared for above parameters.


RESULTS
Patients with higher MIS had higher serum high sensitive C-reactive protein, oxLDL and VCAM-1 levels whereas these patients had lower serum albumin, hemoglobin levels, and FMD rates. MIS was positively correlated with high sensitive C-reactive protein, oxLDL and VCAM-1 levels. However, there was a negative correlation between MIS and FMD. MIS and oxLDL were found as an independent significant predictors of FMD (P = .014 and P = .018, respectively) in a multivariate analysis.


CONCLUSIONS
MIS is a useful tool in prediction of the severity of endothelial dysfunction. Furthermore, decrease in MIS by the modifiable parameters and also treatment of oxLDL could be expected to improve endothelial dysfunction in hemodialysis patients.
