Abstract:
Objective To analyze retrospectively the relationship between protein nutrition index (PNI) and survival conditions in patients with peritoneal dialysis (PD).Methods Various clinical and laboratory indexes of patients with chronic kidney disease from January 2004 to January 2014 were analyzed retrospectively.PNI score was determined by serum albumin (ALB),normalized protein nitrogen presentation rate (nPNA),lean body mass (LBM).According to PNI score,PD patients were divided into four groups:good nutrition status,nutrition status in general,poor nutrition,PEW status.Linear regression analysis was used to analyze determine factors of PNI;analysis of Kaplan-Meier was applied to examine relationship between the protein nutrition status and survival rate;COX regression analysis was used to analyze the risk factors for survival in patients with PD.Results All the indexes,age,complications index,serum Cr,K-Kt/V,T-Kt/V had a linear relationship with PNI.5-year survival rate in the four groups were respectively 95％,92％,65％,23％.Age,complications,PNI index were the survival risk factors of PD patients.Conclusions According to PNI score,evaluation of protein nutritional status of patients with PD could predict survival conditions of PD patients,the higher PNI score,the higher survival rate.
