Abstract

Background

The GNRI (Geriatric Nutritional Risk Index1) is an index used in geriatrics to predict the risk of complications and mortality associated with malnutrition. It considers serum albumin levels and the ratio of current weight or BMI to the ideal theoretical weight/BMI.

Aim

The aim of this study was to evaluate this index in a population of metabolically stable chronic hemodialysis patients aged > 60 years and associate it with other nutritional markers.

Methods

The studied patient cohort was divided into two groups based on their Geriatric Nutritional Risk Index (GNRI) scores: Gr 1 with GNRI score < 97 and Gr 2 with GNRI ≥ 97. We registered the anthropometric, clinical, and biological data of the study population.

Results

One hundred seventy-seven patients (102 M-75F) undergoing chronic hemodialysis were included. There were no differences in age, muscle mass estimated by bioimpedance analysis, potassium levels, phosphorus levels, and nPCR between the groups. However, there were significant differences between the two groups concerning the primary disease. Gr 1 presented with a higher prevalence of diabetes and cardiovascular comorbidities. Additionally, Gr 1 presented with lower handgrip strength (Mean ± standard deviation in kg, 19.79 ± 9.37 vs. 26.83 ± 11.63, p = 0.05), lower fat mass index estimated by bioimpedance analysis (Mean ± standard deviation in kg/m2, 7.31 ± 4.55 vs. 15.24 ± 6.47, p < 0.001), and higher CRP levels (Mean ± standard deviation in mg/l, 22.27 ± 23.49 vs. 8.13 ± 10.14, p < 0.001).

Conclusion

In conclusion, the GNRI, an easy calculation tool for nutrition assessment, is associated with important nutritional status parameters in chronic hemodialysis patients.

慢性血液透析患者老年营养风险指数（GNRI）与其他营养指标的相关性

背景：GNRI（老年营养风险指数1）是一个用于预测与营养不良相关的并发症风险和死亡率的指标。它考虑血清白蛋白水平和当前体重或体重指数与理想理论体重/体重指数之比。目的：本研究的目的是评估代谢稳定的60岁慢性血液透析患者的这一指标，并将其与其他营养指标联系起来。方法：根据患者的老年营养风险指数（GNRI）评分将患者队列分为两组：gr1组，GNRI评分结果：纳入177例（102 M-75F）慢性血液透析患者。两组之间的年龄、生物阻抗分析估计的肌肉质量、钾水平、磷水平和nPCR没有差异。然而，两组在原发疾病方面存在显著差异。1型糖尿病和心血管合并症的患病率较高。此外，Gr 1表现出较低的握力（平均±标准差为kg， 19.79±9.37 vs. 26.83±11.63,p = 0.05），生物阻抗分析估计的脂肪质量指数较低（平均±标准差为kg/m2, 7.31±4.55 vs. 15.24±6.47,p）结论：GNRI是一种简便的营养评估计算工具，与慢性血液透析患者的重要营养状态参数相关。

期刊介绍： Hemodialysis International was originally an annual publication containing the Proceedings of the International Symposium on Hemodialysis held in conjunction with the Annual Dialysis Conference. Since 2003, Hemodialysis International is published quarterly and contains original papers on clinical and experimental topics related to dialysis in addition to the Annual Dialysis Conference supplement. This journal is a must-have for nephrologists, nurses, and technicians worldwide. Quarterly issues of Hemodialysis International are included with your membership to the International Society for Hemodialysis. The journal contains original articles, review articles, and commentary to keep readers completely updated in the field of hemodialysis. Edited by international and multidisciplinary experts, Hemodialysis International disseminates critical information in the field.
