| Summary: | Background: Our objective was to examine the association between the Geriatric Nutritional Risk Index (GNRI) and Total lymphocytes count (TLC) with mortality in Korean Hemodialysis Patients. Methods: We examined the GNRI and TLC of 120 maintenance hemodialysis patients and followed these patients for 120 months. Predictors for all-cause death were examined using life table analysis and the Cox proportional hazards model. Results: Life table analysis revealed that subjects with a GNRI < 90 (n = 19) had a lower survival rate than did those with a GNRI ≥ 90 (n = 101) (Wilcoxon test, P = 0.048), but subjects with a TLC < 1500/mm3 (n = 76)had a similar survival rate compared those with a TLC ≥ 1500/mm3 (n = 44) (Wilcoxon test, P = 0.500). Multivariate Cox proportional hazards analyses demonstrated that the GNRI was a significant predictor of mortality [hazard ratio (HR) 9.315, 95% confidence interval (CI) 1.161–74.753, P = 0.036], after adjusting for age, sex, presence of type 2 diabetes mellitus, Kt/V, nPCR and TLC. The association of a GNRI ≥ 90 with a TLC ≥ 1500/mm3 seemed to exclude the occurring of complications with moderate reliability.
Conclusion: These results demonstrate that the GNRI may be a significant predictor of mortality in Korean hemodialysis patients. However, the use of TLC might improve the evaluation of nutritional risk and the identification of patients at risk of malnutrition.Figure 1.
