Peritoneal dialysis-related peritonitis: can we predict it?

Abstract

Peritonitis complicating peritoneal dialysis represents a major cause of technique failure, hospitalization, and increased mortality. Peritonitis tends to be recurrent and clustered within particular patients at risk. The aim of this review is to evaluate the potential predictive factors for development of peritoneal dialysis-associated peritonitis based on currently available evidence. Risk factors were divided into medical and non-medical ones, and characterized by a schema of fixed versus modifiable factors. A new direction in the landscape change of the risk factors of peritonitis appears to focus on psychosocial aspects and patient training. Identification of these factors have important clinical implications because of the hitherto lack of well-established strategies to prevent peritonitis complicating peritoneal dialysis. It is hoped that better understanding of the risk factors will allow us to take tangible steps toward minimizing the infectious burden from the Achilles' heel of peritoneal dialysis.
