Abstract EN
During peritoneal dialysis (PD), the peritoneal membrane undergoes ageing processes that affect its function.
Here we analyzed associations of patient age and dialysis vintage with parameters of peritoneal transport of fluid and solutes, directly measured and estimated based on the pore model, for individual patients.
Thirty-three patients (15 females; age 60 (21–87) years; median time on PD 19 (3–100) months) underwent sequential peritoneal equilibration test.
Dialysis vintage and patient age did not correlate.
Estimation of parameters of the two-pore model of peritoneal transport was performed.
The estimated fluid transport parameters, including hydraulic permeability (LpS), fraction of ultrasmall pores ( α u ), osmotic conductance for glucose (OCG), and peritoneal absorption, were generally independent of solute transport parameters (diffusive mass transport parameters).
Fluid transport parameters correlated whereas transport parameters for small solutes and proteins did not correlate with dialysis vintage and patient age.
Although LpS and OCG were lower for older patients and those with long dialysis vintage, α u was higher.
Thus, fluid transport parameters—rather than solute transport parameters—are linked to dialysis vintage and patient age and should therefore be included when monitoring processes linked to ageing of the peritoneal membrane.
