Naples Prognostic Score for Graft Functions After Renal Transplantation: A Retrospective Analysis

BACKGROUND: The Naples prognostic score is a comprehensive measure of patients’ inflammation and nutritional status, consisting of serum albumin, total cholesterol, neutrophil/lymphocyte ratio (NLR), and lymphocyte/monocyte ratio (LMR). We compared the Naples prognostic scores of kidney transplant patients with a creatinine reduction ratio of less than 30% vs those with greater than 30%. MATERIAL/METHODS: We conducted a retrospective study on 93 patients who received kidney transplants at our hospital from January 2020 to January 2023. Naples prognostic scores were used to calculate the preoperative condition of transplant recipients. The patients were divided into 2 groups based on their creatinine reduction ratio on the second day after surgery. Group A consisted of patients with a ratio above 30%, while group B consisted of those with a ratio below 30%. RESULTS: Our analysis revealed that the total cholesterol and albumin values of groups A and B showed no substantial difference. Group B had clearly more patients with Naples prognostic score 3–4 compared to the other group (P=0.032). Multivariate analysis determined that patients with Naples prognostic score 3–4 had a 3.151-fold higher likelihood of experiencing creatinine reduction below 30% (95% CI 1.209–8.215, P value 0.019). CONCLUSIONS: The preoperative inflammatory and nutritional status of patients may have an impact on the functioning of grafts during the postoperative period. A high Naples prognostic score may be linked with a decrease in creatinine reduction ratio in post-transplant kidneys, which could lead to graft dysfunction.
