Abstract:
PURPOSE: The aim of this study was to define the reference range of the peritoneal solute transfer in Korean CAPD patients and to investigate the change in peritoneal kinetics in long-term patients. METHODS: Routine PET was done 14 days after catheter break-in in 102 new CAPD patients and using our reference range of PET, the patients were categorized into 4 groups as described by Twardow- ski. In 35 long-term (>3 yrs) CAPD patients, D/Pcr, D/D0 glucose and drain volume in last follow- up (mean duration, 60+/-23 months) PET were compared with those in initial PET. RESULTS: Dialysate to Plasma creatinine ratio (D/ Pcr) at 0 hour, 2 hours and 4 hours was 0.045+/-0.062, 0.408+/-0.151 and 0.612+/-0.154, respectively. D/D0 glucose at 2 hours and 4 hours was 0.594+/-0.129 and 0.398+/-0.121, respectively. Peritoneal solute transfer rate in Korean patients was slightly lower than previously reported results in North American patients (P=0.08). Mean drain volume was 2360+/-270ml and mean residual volume was 436+/-178ml. Drain volume was well correlated with D/D0 glucose (positively, r=0.375, P<0.01) and D/Pcr (negatively, r=-0.345, P<0.01). There were no difference in peritoneal solute transfer, drain volume and residual volume according to sex, age, body surface area and diabetes. In initially high and high average trans- porters, solute transfer rate decreased significantly in followup PET. Out of 7 initially high transporters, 3 remained in high and 4 became high average transporters. Out of 12 initially high average transporters, 3 became low average transporters. Out of 8 initially low average transporters, 2 became high average transporters. And out of 8 initially low transporters, 2 became high average and 1 became high transporters. The number of episodes of perito- nitis do not significantly correlated with the changes of peritoneal solute transport rate. CONCLUSION: These data suggest that peritoneal solute transfer rate in Korean patients is slighthly lower compared with that in North American patients and in long-term CAPD patients the peri- toneal solute transport rate changed to centropetal directions (towards to mean) according to initial PET result.
