The Naples Prognostic Score (NPS), a composite prognostic indicator integrating inflammatory and nutritional status, demonstrates that elevated scores reflect a deteriorating inflammatory-nutritional profile and are independently associated with adverse clinical outcomes in patients with chronic kidney disease (CKD). Percutaneous transluminal angioplasty (PTA) is an important method for evaluating hemodialysis dysfunction. We investigated factors associated with Naples Prognostic Score (NPS) and post-PTA primary patency rate in patients with arteriovenous fistula (AVF), including the Naples Prognostic Score (NPS) and previously reported factors. Previous studies have established the clinical significance of inflammatory biomarkers and nutritional status on arteriovenous fistula (AVF) patency, yet comprehensive assessment integrating both inflammatory and nutritional parameters remains underexplored in patients undergoing percutaneous transluminal angioplasty (PTA). Therefore, this study investigates the impact of the Naples Prognostic Score (NPS)—a composite indicator reflecting systemic inflammation and malnutrition—on 1-year vascular access patency following PTA.
The medical records at our hospital were collected to retrospectively identify and analyze general information, clinical characteristics, and hemodialysis-related factors for post-PTA primary patency in a cohort of 104 patients with AVF who underwent PTA after vascular access construction between January 2019 and December 2024. They were followed up for 12 months. When the patients needed to treat with PTA or AVF reconstruction due to re-occlusion, follow-up was terminated. However, this method is technically difficult, invasive, and unsuitable for frequent clinical use to manage both inflammatory and nutritional parameters. To resolve these problems, the NPS was defined based on ALB, TC, NLR, and LMR. As described in previous literature, participants with serum albumin ≥ 40 g/L, TC > 180 mg/dL, NLR < 2.96, or LMR > 4.44 were assigned a score of 0, while those with serum albumin < 40 g/L, TC ≤ 180 mg/dL, NLR ≥ 2.96, or LMR ≤ 4.44 were assigned a score of 1. The NPS is calculated as the sum of scores for each of the four factors.
Multivariate analysis with the Cox proportional hazard model showed that post-PTA primary patency in patients with AVF is significantly associated with the NPS (hazard ratio 6.331, 95% confidence interval 1.555 ~ 25.767, P<0.05). ROC curve analysis showed that NPS was statistically significant (AUC=0.657, 95% confidence interval 0.560~0.754; P<0.05) and had predictive value. Sensitivity 0.814 (95% CI 0.723 - 0.905), Specificity 0.500 (95% CI 0.332 - 0.668), PPV 0.770 (95% CI 0.674 - 0.866), 净现值 0.567 （95% CI 0.389 - 0.744）.
The Naples Prognostic Score (NPS) is an important predictive factor for post-PTA primary patency in patients with AVF.
