Correlation among the Expression of Serum SORT and IGF-1 Levels in Maintenance Hemodialysis Patients with End Stage Renal Disease and the Occurrence and Prognosis of Cardiovascular Diseases
摘要
Abstract
Objective To investigate the correlation between serum Sortilin(SORT)and insulin-like growth factor 1(IGF-1)levels and the occurrence and prognosis of cardiovascular disease(CVD)in maintenance hemodialysis(MHD)patients with end-stage renal disease(ESRD).Methods Eighty-four MHD patients with ESRD diagnosed and treated in the First People's Hospital of Kunshan from February 2017 to February 2018 were selected as the MHD group.With 5 years of follow-up,the MHD group was divided into the CVD group(n=35)and the non-CVD group(n=49)according to whether they had concurrent CVD,while 60 healthy individuals who underwent physical examination during the same period were used as the control group.Enzyme-linked immunosorbent assay was used to detect serum SORT and IGF-1 levels.Multivariate logistic regression analysis was conducted to investigate the influencing factors of CVD in MHD patients with ESRD.The predictive value of serum SORT and IGF-1 for CVD in MHD patients with ESRD was analyzed by the receiver operating characteristic curve.The correlation between serum SORT and IGF-1 levels and the survival rate of MHD patients with ESRD was analyzed by Kaplan-Meier survival analysis.Results Compared to the control group,the MHD group had higher serum SORT level(413.37±55.41 ng/L vs 81.27±24.69 ng/L)and lower serum IGF-1 level(117.64±18.42 μg/L vs 421.34±14.58 μg/L),with significant differences(t=43.416,106.122,all P＜0.001).The age,dialysis time,and serum SORT level(488.73±55.41ng/L vs 359.54±58.29ng/L)of patients in the CVD group were higher than those in the non-CVD group,while serum IGF-1 level(88.25±17.92 μg/L vs 138.63±19.55μg/L)was lower than that of the non-CVD group,with significant differences(t=2.896,2.588,10.221,12.050,all P＜0.05).Age(OR=1.548,P＜0.001),dialysis time(OR=1.616,P＜0.001)and serum SORT(OR=1.353,P＜0.001)were independent risk factors for CVD in MHD patients,while serum IGF-1(OR=0.742,P=0.000)was a protective factor for CVD in MHD patients.The area under the curve(95％CI)of the combined serum SORT and IGF-1 test for predicting concomitant CVD in MHD patients was 0.931(95％CI:0.895～0.961),which was greater than that of the single detection[0.843(0.810～0.889),0.887(0.833～0.921)],and the differences were statistically significant(Z=5.117,4.895,all P＜0.001).The five-year cumulative survival rate of MHD patients in the SORT high expression group(48.39％)was lower than that in the low expression group(84.81％),while the five-year cumulative survival rate of MHD patients in the IGF-1 low expression group(51.52％)was lower than that in the high expression group(84.31％),and the differences were significant(Log-Rank x2=18.670,8.900,all P＜0.01).Conclusion The serum SORT levels increased while IGF-1 levels decreased in MHD patients.The combined detection of the two has high predictive value for the occurrence of CVD in MHD patients with ESRD,which is associated with poor survival prognosis in MHD patients with ESRD.关键词
