The Naples prognostic score as a nutritional and inflammatory biomarkers of stroke prevalence and all-cause mortality: insights from NHANES.

Abstract

Background: Stroke is a complex neurological condition characterized by high rates of incidence, recurrence, disability, and mortality, making it one of the leading causes of death and disability worldwide. The Naples prognostic score (NPS), an index that combines markers of inflammation and nutritional status, has demonstrated prognostic value in various diseases. This research investigated the relationships among NPS, stroke prevalence, and overall mortality in stroke individuals, drawing on data from the National Health and Nutrition Examination Survey from 2007 to 2018.

Methods: The cross-sectional analysis included 20,798 participants aged beyond 40 years with 1155 persons with stroke analyzed for mortality. Stroke prevalence was self-reported, and the NPS was derived from serum albumin, total cholesterol, the neutrophil-to-lymphocyte ratio, and the lymphocyte-to-monocyte ratio (Galizia et al. in Cancer 60:1273-1284, 2017). Weighted Logistic regression and Cox models assessed associations among NPS, stroke, and mortality, adjusting for demographic and clinical factors.

Results: Higher NPS scores were linked to increased stroke prevalence (OR 3.573, 95% CI 2.745-4.652, P < 0.001) and elevated all-cause mortality risk (HR 3.281, 95% CI 1.978-5.442, P < 0.001) in stroke individuals. The triglyceride-glucose index (TYG) significantly modified the relationship between the NPS and stroke prevalence.

Conclusion: This study supports the clinical utility of the NPS as a predictor of both stroke prevalence and all-cause mortality. The NPS may serve as a valuable tool for risk stratification in stroke prevention and long-term prognosis.
