The influence of peritoneal transport characteristics on the nutritional status of patients with continuous ambulatory peritoneal dialysis

Abstract

Objective To explore the influence of peritoneal transport characteristics on the nutritional status of patients with continuous ambulatory peritoneal dialysis(CAPD).Methods Seventy-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.
