Rationale: Malnutrition represents a critical prognostic factor in patients with end-stage kidney disease. The aim of our retrospective study was to evaluate the nutritional status of patients on the transplant waiting list and identify key factors leading to the development of malnutrition in the pre-transplant period.

Methods: In our retrospective single-center study a total of 313 patients (198 men and 115 women) on the kidney transplant waiting list at the University Hospital Olomouc over the past 25 years were included. Due to the absence of a validated tool for assessing malnutrition risk in patients with kidney disease, we also chose to compare individual scoring systems, utilizing the laboratory PNI and CONUT scores. Nutritional status was further evaluated using a scoring system combining anthropometric parameters (BMI), biochemical markers (albumin, cholesterol, absolute lymphocyte count), and clinical data (duration of dialysis treatment). Based on the final score, patients were stratified into three groups: Group 1 (n=32) with low risk, Group 2 (n=174) with moderate risk, and Group 3 (n=107) with high risk of malnutrition.

Results: More than half of the kidney graft recipients reached moderate-to-high malnutrition risk with results varying depending on the scoring system used. The strongest risk factors included the duration of dialysis treatment, lower levels of cholesterol, albumin, absolute lymphocyte count and BMI.

Conclusion: Systematic nutritional risk stratification is essential for the early identification of high-risk kidney transplant candidates. Targeted nutritional intervention in the pre-transplant phase can significantly reduce morbidity and improve the metabolic stability of patients during the perioperative period. Nutritional screening should be an integral part of the pretransplant care protocol.
