The Nutritional and Inflammatory Evaluation in Dialysis patients (NIED) study: overview of the NIED study and the role of dietitians.

The absolute majority of maintenance hemodialysis (MHD) patients die within 5 years of commencing dialysis treatment, mostly because of cardiovascular (CV) disease. The strongest and most common correlates of death in MHD patients are not conventional CV risk factors, but markers of protein-energy malnutrition and inflammation, together also known as malnutrition-inflammation complex syndrome (MICS). Paradoxically, classic risk factors such as obesity and hypercholesterolemia are associated with better survival in MHD patients.
