Abstract:
Objective:To investigate the relationship between triglyceride glucos (TyG), C-reaction protein/albumin (CRP/Alb), 25-hydroxy vitamin D[25(OH)D] and the prognosis of patients with continous ambulatory peritoneal dialysis (CAPD).Methods:A total of 220 CAPD patients in the Affiliated Hospital of Jining Medical University from January 2017 to March 2020 were prospectively selected and divided into death group and survival group according to the 6-month prognosis. The peritoneal urea clearance index (Kt/V urea), TyG, CRP/Alb, 25(OH)D were compared between the two groups. Logistic regression was used to analyze the prognostic factors of CAPD patients. The predictive value of TyG, CRP/Alb and 25(OH)D on the prognosis of CAPD patients was analyzed by receiver operating characteristic (ROC) curve. Results:After 3 months and 6 months of dialysis, the peritoneal Kt/V urea in the death group [(1.21±0.18)ml/(s·1.73 m 2), (1.02±0.14)ml/(s·1.73 m 2)] was significantly lower than that in the survival group [(1.57±0.40)ml/(s·1.73 m 2), (1.49±0.42)ml/(s·1.73 m 2)] (all P<0.05). After 3 months and 6 months of dialysis, the TyG [(8.79±0.86), (9.24±1.03)] and CRP/Alb [(4.98±0.94)×10 -4, (5.14±1.39)×10 -4] in the death group were higher than those in the survival group [(8.03±0.60), (7.26±0.93), (3.57±1.19)×10 -4, (3.07±0.88)×10 -4], while the 25(OH)D [(19.14±2.29)ng/ml, (17.79±3.17)ng/ml] was lower than that of survival group [(22.67±3.03)ng/ml, (24.31±2.51)ng/ml] (all P<0.05). TyG and CRP/Alb at 3 months and 6 months of dialysis were negatively correlated with Kt/V urea, while the 25(OH)D was positively correlated with Kt/V urea (all P<0.05). Logistic regression analysis showed that Kt/Vurea, TyG, CRP/Alb and 25(OH)D were associated with prognosis in the two groups after 3 and 6 months of dialysis (all P<0.05). The AUC of TyG, CRP/Alb and 25(OH)D at 6 months of dialysis combined to predict the prognosis of CAPD patients was the highest, which was 0.911. Conclusions:TyG, CRP/Alb and 25(OH)D are associated with all-cause mortality in CAPD patients. High TyG and CRP/Alb and low 25(OH)D suggest a higher risk of all-cause mortality. Combined detection of all indicators can effectively predict the prognosis of CAPD, which is convenient for early clinical intervention.
