Impact of personalized nutritional intervention on nutritional status and quality of life of maintenance hemodialysis patients with protein energy wasting

BACKGROUND: Protein energy wasting (PEW) is a common multifactorial problem affecting maintenance hemodialysis (MHD) patients. OBJECTIVES: We aimed to explore the impact of personalized nutritional intervention on nutritional status and quality of life (QOL) in MHD patients. METHODS: Interventional study included 18 MHD patients suffering from PEW. They were subjected to personalized nutritional intervention for 6 months according to Kidney Disease Outcomes Quality Initiative (KDOQI) Clinical Practice Guidelines (2000). QOL was evaluated by using the Kidney Disease Quality of Life (36 KDQOL-36). Nutritional status and QOL of those patients were re-assessed after 6 months and compared to those at the baseline. RESULTS: Fourteen patients completed six months of the study. Following such intervention, half of these patients became no longer suffering from PEW (responder group). Most of the nutritional and QOL data improved in the responder in contrary to the non-responder group of patients. The baseline level of parathyroid hormone (PTH) was significantly higher but physical health was significantly lower in non-responder than responder groups. CONCLUSIONS: Implementation of an internationally acknowledged nutritional program could improve the nutritional status and QOL of MHD patients with PEW. Moreover, PTH level, and physical health of the studied patients could contribute to the positive response to nutritional intervention.
