Serum KIM-1, NGAL, and NAG Levels and Correlation with the Diagnostic Value in Patients with Fracture Traumatic Shock

Abstract

Traumatic shock is the most common cause of serious adverse outcomes in patients with severe traumatic diseases such as fractures, and some studies here have shown that the main cause of death from traumatic shock is the impairment of organ function that occurs after shock. In this study, we explored the role of serum kidney injury molecule-1 (KIM-1), neutrophil gelatin-related lipid transporter protein (NGAL), and N-acetyl-β-D-glucosidase (NAG) levels in evaluating and diagnosing the condition of patients with fracture traumatic shock based on the goal of contributing to the clinical diagnosis of the patient’s condition as soon as possible and taking measures to alleviate its progress. 96 patients with fracture traumatic shock were included in the study as the observation group and 58 healthy examiners as the control group, and the observation group was divided into 69 cases in the mild-moderate group and 27 cases in the severe group according to the Acute Physiology and Chronic Health Status Scale (APACHE-II). In this study, we detected and analyzed the differences in serum KIM-1, NGAL, and NAG levels between the observation group and the control group and the observation group with different disease levels. We found that the observation group was significantly higher than the control group, and the severe patients were higher than the mild to moderate patients, and we observed that serum KIM-1, NGAL, and NAG are significantly correlated with the condition of patients with fracture traumatic shock after further analysis using the Pearson model. In addition, the diagnostic value of receiver operating characteristic curve analysis showed that the AUC of serum KIM-1 for the diagnosis of fracture traumatic shock was 0.755, the AUC of serum NGAL was 0.750, the AUC of serum NAG was 0.772, and the AUC of the combination of the three indicators was 0.915. The results of this study thus suggest the possibility of serum KIM-1, NGAL, and NAG as clinical indicators for evaluating the condition of patients with fracture traumatic shock and the possibility of a combined test of serum KIM-1, NGAL, and NAG for diagnosing the condition.
