OBJECTIVE: To provide a practical overview of methods for assessing and monitoring nutritional status in patients undergoing PD, as well as the main dietary strategies aimed at preventing or correcting malnutrition. METHODS: A literature search was conducted in the PubMed and Embase databases for publications published between 2000 and 2025. The search included the following keywords: peritoneal dialysis, nutrition, protein-energy wasting, nPNA, dietary management, and nutritional assessment. International guidelines from the Kidney Disease Outcomes Quality Initiative (KDOQI), the International Society of Renal Nutrition and Metabolism (ISRNM), and the French National Authority for Health (HAS), together with observational studies, clinical trials, and relevant reviews on nutritional monitoring in PD, were analyzed. RESULTS: Nutritional assessment in PD relies on a multidimensional approach combining biological markers (albumin and prealbumin, interpreted in the context of inflammation); composite indices including the malnutrition-inflammation score (MIS), prognostic nutritional index (PNI), and subjective global assessment (SGA); evaluation of dietary intake; and functional tools such as handgrip strength and bioimpedance analysis. Calculation of normalized protein nitrogen appearance (nPNA) provides a useful indicator of protein intake and helps guide nutritional prescriptions. Current recommendations advocate a protein intake of approximately 1.2-1.3 g/kg/day, adjusted ...
