Small solute transport and fluid kinetics in 23 patients investigated with an extended transport analysis using intraperitoneally administered dextrana

ParameterAll Patients (n = 23)CAPD (n = 9)APD (n = 14)PD ≥40 mo (n = 12)PD <40 mo (n = 11)Peritonitis Episodes >10 (n = 10)Peritonitis Episodes =0 (n = 13)
a CAPD, continuous ambulatory peritoneal dialysis; APD, automated peritoneal dialysis; PD, peritoneal dialysis; BSA, body surface area; CrCl creatinine clearance; Kt/V, urea removal index; GFR, glomerular filtration rate [CrCl + urea clearance)/2] D/P ratio, dialysat/plasma ratio of creatinine; MTAC, mass transfer area coefficient; LAR, lymphatic absorption rate; TCUF, transcapillary ultrafiltration; UF, effective ultrafiltration.
b P ≤ 0.01 between long-term and short-term PD patients.
c P ≤ 0.05 between patients with and without a peritonitis episode. After correction for different treatment time (62 ± 9 versus 29 ± 6 mo), no significance was found between patients with or without an episode of peritonitis.
d P ≤ 0.05 between long-term and short-term PD patients.
