Abstract:
Objective:To explore the relationship between end-dialysis over-weight (edOW) in initial stage of hemodialysis and long-term prognosis in maintenance hemodialysis patients.Methods:The data of initial uremia patients receiving hemodialysis in the First Affiliated Hospital, College of Medicine, Zhejiang University from January 1, 2008 to April 30, 2017 were retrospectively analyzed. The end point of follow-up was death or until April 30, 2018. The general data including age, gender, body mass index, primary disease, complications and laboratory indicators of the patients and the related parameters of dialysis from four to twelve months were collected. Kaplan-Meier method was used to analyze survival rate. Cox multivariate regression was used to analyze the relationship between edOW and all-cause mortality and cardiovascular disease (CVD) mortality.Results:A total of 469 patients (300 males, 64.0%) were enrolled, with age of (56.9±17.1)years old. During the follow-up period of (4.1±2.4) years (1.0-10.3 years), 102 patients died. The main cause of death was cardiovascular and cerebrovascular events, accounting for 44.1% (45/102). The value of edOW was (0.28±0.02) kg. The patients were divided into edOW<0.28 kg group ( n=292) and edOW≥0.28 kg group ( n=177) according to the mean value of edOW. Kaplan-Meier survival analysis showed that the long-term survival rate in edOW<0.28 kg group was higher than that in edOW≥0.28 kg group (Log-rank χ2=4.134, P=0.043), and the CVD mortality in edOW≥0.28 kg group was significantly higher than that in edOW<0.28 kg group (Log-rank χ2=11.136, P=0.001). Cox multivariate regression analysis showed that high edOW was an independent influencing factor for all-cause death and CVD death in hemodialysis patients ( HR=1.541, 95% CI 1.057-2.249, P=0.025; HR=1.930, 95% CI 1.198-3.107, P=0.007). Conclusion:High edOW in early phase is an independent influencing factor of all-cause and CVD death in hemodialysis patients.
