The relationship between serum levels of LOX-1, hs-cTnT, NGAL, and renal function, and their diagnostic value in patients with chronic kidney disease: a retrospective study.

Abstract

Background: The primary aim of this study is to explore the relationship between serum levels of LOX-1, hs-cTnT, and NGAL, and renal function in patients with CKD, as well as to evaluate their diagnostic value for early detection and monitoring of disease progression in CKD patients.

Methods: A retrospective study was conducted on 108 patients with chronic kidney disease admitted to our hospital from January 2023 to December 2023. The patients were divided into the mild renal insufficiency group (51 cases) and the severe renal insufficiency group (57 cases). The differences in serum levels of LOX-1, hs-cTnT, and NGAL between the two groups were compared, and Pearson correlation analysis was used to explore the relationship between the three levels and renal function. ROC analysis was used to evaluate the predictive value of the three markers for the diagnosis of CKD.

Results: The levels of LOX-1, hs-cTnT, and NGAL in the mild renal insufficiency group were lower than those in the severe renal insufficiency group (P < 0.05). Correlation analysis showed that serum levels of LOX-1, hs-cTnT, and NGAL were positively correlated with the deterioration of renal function (P < 0.001), indicating a significant correlation between LOX-1, hs-cTnT, NGAL levels, and the deterioration of renal function. ROC analysis showed that the AUC of serum levels of LOX-1, hs-cTnT, and NGAL were 0.859, 0.882, and 0.841, indicating a significant predictive value for the diagnosis of chronic kidney disease.

Conclusion: Serum levels of LOX-1, hs-cTnT, NGAL, and related markers demonstrate a direct association with the extent of renal impairment, offering predictive capabilities for diagnosing CKD.
