Long-term continuous ambulatory peritoneal dialysis (CAPD) patients maintain stable nutritional status. Older patients may require lower protein intake to preserve serum albumin levels.

Area of Science:

  • Nephrology
  • Nutritional Science

Background:

  • Continuous ambulatory peritoneal dialysis (CAPD) is a treatment for end-stage renal disease.
  • Nutritional status is a critical factor in long-term CAPD patient outcomes.
  • Understanding protein and nutrient metabolism in CAPD patients is essential for optimizing care.

Purpose of the Study:

  • To evaluate nutritional markers, including normalized urea nitrogen appearance (NUNA), normalized protein catabolic rate (NPCR), and normalized daily creatinine excretion (NDCE), in long-term CAPD patients.
  • To assess changes in serum albumin and transferrin over time in these patients.
  • To investigate the relationship between nutritional markers, patient age, and duration of CAPD.

Main Methods:

  • Studied 21 CAPD patients (15 men, 6 women; mean age 63 years) with over 4 years of dialysis.

  • Measured NUNA, NPCR, NDCE, serum albumin, and serum transferrin.
  • Compared current data with initial measurements from the same patients.

    • Main Results:

    • Long-term CAPD (mean 80 months) showed stable NUNA, NPCR, and NDCE.
    • NPCR correlated with NUNA and NDCE.
    • NPCR decreased with increasing patient age, but serum albumin and transferrin remained stable over time.
    • No significant changes in NUNA, NPCR, or NDCE were observed when comparing current data to initial measurements.

    Conclusions:

    • Long-term CAPD does not inherently compromise nutritional status.
    • Older CAPD patients may maintain stable serum albumin with reduced protein intake compared to younger patients.
    • Nutritional markers remain stable over extended periods of CAPD therapy.
