Abstract:
ObjectiveTo evaluate the characteristics of patients on long-term peritoneal dialysis (PD). MethodsPatients who started PD since 1994 and received PD for at least one year were included in this study. According to dialysis duration, patients were divided into two groups. Group A (long-term) was defined as patients survived on PD for more than 5 years. Group B (short-term) was defined as patients who died or switched to bemodialysis within less than 5 years. Demography, biochemical indexes, dialysis prescription and adequacy were compared between two groups. ResultsThere were 68 patients in group A and 98 patients in group B. Mean followed-up period of group A and B was (84.80±19.42) months and (27.25±12.31) months, respectively. Younger, fewer episodes of diabetic comorbidity (group A 3/68 vs group B 18/98, P ＜0.05) and coronary heart disease (group A 6/68 vs group B 22/98, P＜0.05) were found in group A. Compared to group B, the level of serum albumin at the beginning of PD was much higher in group A [(35.56±4.74) g/L vs (33.69±5.45) g/L, P＜0.01). The levels of blood sugar, TC, TG, hemoglobin, calcium, phosphate and iPTH were not significantly different between two groups. Estimated GFR, renal Kt/V and renal Ccr at the beginning of dialysis were much higher in group A, however there was no significant difference in urinary volume between two groups. Both estimated GFR and urinary volume decreased more slowly in group A compared to group B. Peritonitis mobidity was lower in group A (1/81.22 months vs 1/29.03 months, P＜0.01). Conclusions In comparison to short-term survivors, long-term PD patients are characterized by being younger, less diabetic and coronary heart disease, fewer episodes of peritonitis, higher level of serum albumin, higher estimated GFR and less loss of residual renal function.
