Abstract:
Objective:To investigate the relationship between peritoneal thickness and baseline solute transport function in peritoneal dialysis (PD) patients, and analyze the factors affecting the function of peritoneal transport.Methods:Non-diabetic end-stage renal disease (ESRD) patients admitted to the Second Hospital of Longyan City from January 2017 to June 2019 were enrolled in this study. The thickness of the peritoneal membrane was measured by color ultrasound instrument before the peritoneal catheterization. Standard peritoneal equilibration test (PET) was performed after one month of peritoneal dialysis. The ratio of corrected creatine in 4 h dialysate to 2 h serum creatine (D/Pcr) was used as a solute baseline transport index, and according to the D/Pcr evaluation results, the patients were divided into high/high average transfer (H) group (D/Pcr≥0.65) and low/low average transfer (L) group (D/Pcr<0.65). The clinical data, peritoneal thickness and peritoneal dialysis related indicators between the two groups of patients were compared. Binary logistic regression was used to analyze the factors affecting the function of peritoneal transport.Results:The amount of peritoneal ultrafiltration in H group was significantly lower than that in L group, intraperitoneal creatinine clearance (Ccr) and peritoneal thickness were significantly higher than those in L group (both P<0.05). Pearson and Spearman correlation results showed that the thickness of peritoneal membrane positively correlated with D/Pcr ( r=0.673, P<0.05), peritoneal Ccr ( r=0.261, P<0.05), and negatively correlated with ultrafiltration of peritoneal dialysis ( r=-0.365, P<0.05). Partial correlation analysis showed that the peritoneal thickness was positively correlated with the solute transport index D/Pcr ( r=0.539, P<0.05) and the peritoneal Ccr ( r=0.338, P<0.05). Binary logistic regression results showed that peritoneal thickening was a risk factor affecting peritoneal transport function ( OR=1.175, 95% CI 1.009-1.369, P<0.05). Conclusions:There is a positive correlation between the peritoneal membrane thickness and the baseline solute transport index in patients with non-diabetic peritoneal dialysis. Peritoneal thickening is a risk factor affecting peritoneal transport function.
