Summary

Peritoneal dialysis (PD) maintains stable balances and preserves residual renal function (RRF). Combining PD with hemodialysis (HD) when RRF declines offers a strategy for effective solute removal and ultrafiltration, potentially enabling daily dialysis.

Area of Science:

  • Nephrology
  • Renal Replacement Therapy

Background:

  • Peritoneal dialysis (PD) offers continuous solute, electrolyte, and fluid balance, preserving residual renal function (RRF).
  • Declining RRF in PD necessitates increased dialysis dose and ultrafiltration to prevent complications.
  • PD's limitations include decreasing ultrafiltration (UF) volume and solute removal over time, while hemodialysis (HD) is intermittent.

Purpose of the Study:

  • To propose a combined therapy strategy integrating PD and HD.
  • To optimize dialysis delivery by leveraging the strengths of both PD and HD.
  • To achieve enhanced solute removal and ultrafiltration, potentially leading to 'real' daily dialysis.

Main Methods:

  • Initiate PD at the start of dialysis to complement RRF.
  • Transition to combined PD and HD therapy as RRF declines.
  • Adjust PD prescription and increase HD frequency (e.g., three sessions/week) with low-volume PD on non-HD days.

Main Results:

  • The proposed integrated approach aims to compensate for PD's declining UF and solute removal.
  • It addresses HD's intermittent nature by providing continuous support.
  • Successful integration could lead to a 'real' daily dialysis regimen.

Conclusions:

  • Combined PD and HD therapy offers a structured approach to manage declining RRF.
  • This strategy leverages PD's continuous benefits and HD's solute clearance capabilities.
  • The integration holds promise for achieving effective and potentially daily dialysis treatments.
