Abstract

Background: Chronic exposure to peritoneal dialysis (PD) fluid is associated with development of functional and structural alterations of the peritoneal membrane. The exact time point at which these changes actually occur is not known. Whether changes to the peritoneum occur immediately after installation of PD fluids and whether there is a difference between neutral-pH, low glucose degradation product (low-GDP) PD fluids and conventional PD fluids is not known either. Materials and methods: We performed an observational study. Markers related to inflammation, fibrosis, mesothelial activation, and cytokines/growth factors were measured in effluents immediately after PD-catheter insertion and during the first days and weeks of PD treatment in patients using either dianeal ® or physioneal®. Results: Peritoneal response was observed instantly upon insertion of the PD catheter and instillation of PD fluids and persisted during daily PD therapy. Particularly during the first contacts of the peritoneum with PD fluids, high levels of cytokines and biomarkers were observed. In general, CA125 is slightly higher with dianeal. There is no difference between the fluids in hyaluronic acid (HA), IL-6, IL-8, MCP-1, VEGF, and TGFβ-1 levels. Conclusion: Implantation of the Tenckhoff catheter and installation of PD fluids induce inflammation, which in the first days resembles an acute inflammatory response. More continuous infusion of PD fluids further enhances peritoneal inflammation. The use of the bicarbonate/ lactate-buffered, neutral-pH, low-GDP PD fluid physioneal exerts lower CA125 levels, lower D/P4 creatinine, but similar inflammatory response compared to conventional dianeal PD fluids in this early stage of PD therapy.
