Nutrition in Peritoneal Dialysis.
Malnutrition and protein-energy wasting are increasingly recognized, multifactorial complications in peritoneal dialysis patients, and this review emphasizes structured nutritional assessment alongside updated targets for caloric, protein, and micronutrient intake.
Background
Peritoneal dialysis (PD) is associated with improved quality of life, cost-effectiveness, and outcomes for patients with kidney failure, but many PD patients face nutritional challenges. As PD use grows worldwide, malnutrition and protein-energy wasting have become increasingly recognized concerns that the nephrology community must identify and treat to maintain optimal nutritional status.
Key recommendations
The review summarizes contributors to malnutrition and protein-energy wasting in PD, including inadequate nutrient intake, inflammation, dialysate protein losses, and continuous glucose absorption from PD solutions. It examines the benefits and limitations of nutritional parameters used to assess protein-calorie malnutrition and emphasizes updated guidance on daily caloric, protein, and micronutrient recommendations and their effects on electrolyte homeostasis. Adequate dietary protein intake is highlighted as central; supporting cohort evidence has linked intakes below roughly 0.8 g/kg/day to worse survival in PD populations.
Clinical implications
Clinicians caring for PD patients should perform careful and periodic nutritional assessment and apply individualized dietary counseling to prevent and treat protein-energy wasting. Where intake remains insufficient, oral nutritional supplements and, in selected patients, parenteral approaches may be considered. As a narrative review, the work synthesizes existing recommendations rather than reporting new trial data.
