Abstract:
Objective:To explore the correlation between protein energy wasting(PEW)and frailty in elderly patients on maintenance hemodialysis(MHD)and influencing factors of frailty.Methods:Clinical data of patients over 60 who had received regular hemodialysis treatment at Beijing Huairou Hospital between September to December 2021 were collected.According to Fried's evaluation criteria, patients were divided into a frailty group and a non-frailty group, and differences between the two groups were compared.Spearman correlation analysis was conducted to assess the correlation between protein energy wasting and frailty.Logistic regression was used to analyze the influencing factors of frailty in elderly patients on MHD.Results:A total of 81 MHD patients enrolled in this study, with 36 in the frailty group.The frailty group was older, had a higher proportion of patients with PEW, and underwent more months of dialysis, with a higher proportion of patients with diabetic nephropathy as the primary disease, having high levels of C-reactive protein(CRP), and having low KT/V, hemoglobin, albumin, body mass index(BMI), mid-arm circumference(MAC)and mid-arm muscle circumference(MAMC), and the differences with the control group were statistically significant(all P<0.05). The Fried frailty phenotype was positively correlated with age( r=0.021, P=0.047), but negatively associated with HGB( r=-0.329, P=0.003), albumin( r=0.021, P=0.047), BMI( r=0.021, P=0.047), TSF( r=-0.274, P=0.013), MAC( r=-0.554, P<0.001)and MAMC( r=-0.293, P=0.008). A Logistic regression equation was constructed using frailty as the dependent variable.The results showed that age, months of dialysis, KT/V, serum albumin and CRP were independent factors influencing the development of frailty in elderly patients with MHD. Conclusions:PEW and frailty coexist and interact with each other in elderly patients with MHD.Clinicians should place emphasis on the assessment of frailty and protein energy wasting in elderly dialysis patients and achieve early detection and intervention to avoid adverse clinical outcomes.
