Clinical Causes of Inflammation in Peritoneal Dialysis Patients

Table 1

Summary of proposed mechanisms underlying clinical causes of inflammation in peritoneal dialysis patients and possible treatment options.

Clinical causes of inflammationProposed mechanismPossible treatment options

Loss of residual renal function(i) Impaired renal clearance of inflammatory cytokines
(ii) Direct stimulation of cytokine generation by uraemic milieu
(iii) Adverse effect of inflammation on residual renal function
Strategies to improve residual renal function, such as
(i) avoidance of nephrotoxic agents or acute kidney injuries
(ii) use of biocompatible PD solutions

Peritoneal dialysis: use of conventional peritoneal dialysis solutions(i) Cumulative peritoneal membrane injury
(ii) Glucose degradation product mediated nephrotoxicity
Use of biocompatible solutions characterised by neutral pH, low glucose degradation product content

Peritoneal dialysis cathetersBiofilm formation within the catheter lumenUse of catheters resistant to biofilm formation

Peritoneal dialysis-related peritonitisInduces acute inflammatory response Peritonitis prevention strategies:
(i) disconnect systems (twin-bag and Y-set)
(ii) preoperative administration of intravenous antibiotics prior to PD catheter insertion
