Introduction
• Malnutrition in hemodialysis (HD) is a well-described condition, often co-existing with inflammation
• It affects 50 to 75% of HD, depending on the diagnostic tool used.

Aim of the study
• Explore the prevalence of malnutrition using the malnutrition inflammation score (MIS) and Phase Angle (PhA)
• Compare their concordance with the new Global Initiative on Malnutrition (GLIM) criteria for the diagnosis of malnutrition.

Methods • Design and sample
– Cross sectional study
– Randomly recruited HD unit in United Arab Emirates
• Outcome variables
– MIS, malnourished >10
– Malnutrition assessment based on GLIM criteria
• FFMI for men <17kg/m2 , <15kg/m2
– Phase angle (PhA), derived from BIA analysis
• Statistical analysis
– Independent – test and Mann-Whitney U non parametric test, SPSS 21
– Receiver Operating Characteristic (ROC curves), Medcalc software

Conclusions
• Malnutrition is highly prevalent in the HD patients studied.
• MIS performed slightly better than PhA in the diagnosis of malnutrition
when using GLIM as a reference
• Both tools may perform equally on a large sample.
• Prioritizing malnutrition screening in this population, and integrating cost-
effective, sensitive and specific tools within routine practice is essential for
this population
