Abstract
Purpose
The main purpose of this study is to correlate the significance of the malnutrition inflammation score (MIS) and the waist-to-hip ratio (WHR) in the prediction of mortality in hemodialysis patients.
Methods
The study was conducted from March 2016 to April 2020, covering 100 hemodialysis patients. Anthropometric measures (Waist circumference (WC), Hip circumference (HC), Waist-to-hip ratio (WHR), Caliper and BMI) and biomarkers of inflammation (IL6, hsCRP) and nutrition (Transfferin, Albumin) were determined and for the above-mentioned biomarkers, we monitored all-cause mortality for 4 years. The hemodialysis patients were divided in three groups based on their MIS score.
Results
In this prospective, longitudinal study, we enrolled 100 patients (54 males and 46 females) with a median age of 58 (51–65) years. All patients were divided into three groups according to MIS score values. We performed univariate Cox regression survival analysis for a period of 4 years, and then included for multivariate survival Cox regression analysis well-defined nutritional markers: BMI, mid-arm circumference, WHR and MIS score. The MIS score was demonstrated to be the best independent predictor of 4-year mortality in our study (p < 0.001).
Conclusion
The results of our study have shown that there is no significance of WHR in the prediction of mortality in hemodialysis patients, but that the MIS score is a strong, independent predictor of all-cause 4-year mortality.
