Baseline peritoneal solute transport rate (PSTR) as measured by the peritoneal equilibration test (PET) within 6\u2009months after PD initiation varies between patients. Sodium is reported to be stored in the skin or muscle of dialysis patients. This study investigated whether excessive salt intake in uremic mice caused peritoneal alterations without exposure to PD fluid.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Sham-operated (Sham) and subtotal nephrectomized (Nx) mice were randomly given tap water or 1% sodium chloride (NaCl)-containing water for 8\u2009weeks.

Blockade of interleukin (IL)-6 signaling rescued peritoneal transport function in Nx\u2009+\u2009salt mice. In cultured Met-5A, additional NaCl in the medium upregulated IL-6 as well as vascular endothelial growth factor-A, associated with increased expression and nuclear translocation of tonicity-responsive enhancer binding protein (TonEBP). Knockdown of TonEBP lowered the induction caused by high tonicity. Peritoneal TonEBP expression was higher in Nx\u2009+\u2009salt mice, while removal of high-salt diet lowered TonEBP level and improved peritoneal transport function.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Excessive dietary salt intake caused peritoneal membrane functional and structural changes under uremic status.
