Summary

Peritonitis significantly impacts peritoneal dialysis in children. Repeated peritoneal equilibration tests show decreased creatinine transport after peritonitis episodes, affecting long-term dialysis effectiveness.

Area of Science:

  • Pediatric Nephrology
  • Renal Replacement Therapy

Background:

  • Continuous peritoneal dialysis (CPD) is a key treatment for pediatric kidney failure.
  • Peritoneal equilibration test (PET) assesses peritoneal membrane function during dialysis.
  • Understanding longitudinal changes in PET is crucial for optimizing pediatric CPD therapy.

Purpose of the Study:

  • To evaluate longitudinal changes in the peritoneal equilibration test (PET) in children undergoing continuous peritoneal dialysis (CPD).
  • To investigate the impact of prolonged CPD and peritonitis episodes on PET parameters.

Main Methods:

  • PET was performed up to five times in 12 pediatric patients over a mean interval of 22.8 months.
  • Patients were divided into groups with and without peritonitis.
  • Dialysate/plasma (D/P) creatinine and dialysate/initial dialysate (D/Do) glucose ratios were analyzed.

Main Results:

  • In the peritonitis group (n=6), the 4-h D/P creatinine ratio decreased progressively over time.
  • The final D/P creatinine ratio was significantly lower than the initial PET in the peritonitis group (P < 0.01).
  • No significant changes in D/P creatinine or D/Do glucose ratios were observed in the non-peritonitis group (n=6).

Conclusions:

  • Prolonged CPD itself does not affect creatinine membrane permeability.
  • Peritonitis episodes lead to a decrease in peritoneal membrane permeability for creatinine over time.
  • PET is a valuable tool for monitoring sequential changes in peritoneal function in pediatric CPD patients.
