Recent advances in the management of peritoneal dialysis patients

Abstract

Peritoneal dialysis is a form of kidney dialysis that is used to remove accumulated metabolic waste products and water in patients with end stage kidney disease. Long-term exposure to high concentrations of glucose and its by-products, both found in peritoneal dialysis fluid, has been implicated in contributing to peritoneal damage over time, in turn limiting long-term use of the technique. Newer peritoneal dialysis solutions have been developed in the hope of reducing the unfavorable effects of peritoneal dialysis solutions. In vitro and in vivo studies have suggested that newer peritoneal dialysis fluids have salutary effects on the peritoneal membrane. Short-term clinical studies have also found some metabolic benefits of glucose-sparing regimens in chronic peritoneal dialysis. Mixed results have been found in studies examining whether newer peritoneal dialysis fluids reduce peritonitis rates. Long-term studies are needed to investigate whether newer peritoneal dialysis fluids provide better peritoneal dialysis technique and/or patient survival, compared to standard glucose-based peritoneal dialysis fluids.
