ObjectiveTo explore the influence of peritoneal transport characteristics on the nutritional status of patients with continuous ambulatory peritoneal dialysis(CAPD).MethodsSeventy-three CAPD patients were involved in this cross-sectional study.According to the results of peritoneal equilibration test(PET),the patients were divided into high transport group with 43 cases and low transport group with 30 cases.Nutritional status was evaluated with the subjective global assessment (SGA) score and the differences were analyzed between two groups in the albumin (ALB),total protein (TP),hemoglobin (Hb),primary disease,age,weight,dialysis time,ultrafiltration,blood urea nitrogen ( BUN ),serum creatinine (SCr) and so on.Results There was no difference between two groups in age,weight,ultrafiltration,systolic blood pressure,diastolic blood pressure,Hb,SGA score,BUN and SCr (P＞0.05).However,the dialysis time,the case number of diabetic nephropathy (DN) as original disease,the case number of non DN as original disease,TP and ALB between high transport group and low transport group had significant differences [(14.35±13.88) months vs.(24.20 ±19.62) months,16 cases vs.12 cases,27 cases vs.18 cases,( 64.98±7.59 ) g/L vs.( 68.73 ± 6.96 ) g/L,( 34.61 ± 5.43) g/L vs.( 38.71±3.82 ) g/L,P ＜ 0.05 ].Conclusions The nutritional status of CAPD patients with different transport characteristics have significant differences.CAPD patients with high transport characteristics are complicated with worse nutritional status,compared with those patients with low transport characteristics.

Objective To evaluate the influence of peritoneal transport characteristics on nutritional status of peritoneal dialysis patients and estimate the role of peritoneal transport characteristics and nutritional status in evaluation of peritoneal dialysis adequacy. Methods Peritoneal transport properties (D/Pcr) were evaluated by Short Peritoneal Equilibration Test and then 53 cases were divided into high transport group (D/Pcr ≥0. 65) and low transport group (D/Pcr < 0. 65). Urea kinetics (Kt/v) and total clearance of creatinine (TCcr) were calcu- lated. Serum albumin (ALB), prealbumin, transferring (TF), hemoglobin (Hb), lean body mass (LBM) and LBM% were examined or calculated. Subjective global assessment (SGA) was used to evaluate the nutritional sta- tus of patients. Results There were 30 cases in high transport group and 23 cases in low transport group. D/Pcr (0. 82±0.15 vs. 0. 55±0. 08, P < 0. 01), TCcr (62. 93%±25. 98% vs. 49. 69%±16. 92% , P < 0. 05) and age were significantly higher in high transport group than those in low transport group, while ALB, TF, Hb, LBM% , and SGA were significantly lower than those in low transport group (P < 0.05). ALB was negatively cor-related with Kt/v (r= -0.2708, P<0. 05). Conclusions High peritoneal transport patients have better solute clearance but worse nourishment status compared with low transport ones. Nutritional status is one of the factors to evaluate dialysis adequacy. Nutrition management and guidance should be strengthened for the continuous ambula- tory peritoneal dialysis patients, especially for the elderly ones.
