• W2920787719 abstract "Objective Malnutrition is a frequent complication in patients on hemodialysis (HD), even if its adequate appraisal remains one of the most complicated challenges in the HD scenario because of the limits of current malnutrition biomarkers. The aim of our study was to assess the relation of subjective nutritional tools Subjective Global Assessment (SGA) and Dialysis Malnutrition Score (DMS) with the objective malnutrition tool Geriatric Nutritional Risk Index (GNRI) in elderly patients on HD. Methods This is a cross-sectional study involving 71 patients on maintenance HD. Mann-Whitney U and chi-square tests were used to compare data of male and female patients on HD. Linear and logistic regression models were used to assess the variables tested in all patients. Results GNRI was not different between male and female patients on HD, and it was negatively related to SGA and DMS: B, −0.05 (95% confidence interval, −0.08 to −0.02) P = 0.00 and B, −0.30 (95% confidence interval, −0.47 to −0.14) P = .00, respectively. Both continuous and categorical GNRI data were predictive of SGA = 3: Odds Ratio (OR), 0.74 (0.63 to 0.87) P = 0.00 and OR, 6.74 (1.54 to 29.45) P = 0.01, respectively. Similarly, GNRI data were related to DMS > 13: OR, 0.85 (0.76 to 0.85) P = 0.00 and 3.29 (1.08 to 10.05) P = 0.03, respectively. Continuous GNRI data remained significant in both male and female patients separately, whereas categorical GNRI data, only in male patients. Conclusions GNRI is a reliable nutritional tool predictive of subjective malnutrition scores SGA and DMS, pointing out a relation between objective and subjective malnutrition indexes in both genders.
