ABSTRACT
OBJECTIVE:
In order to assess the relationships between the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio, and systemic immune inflammatory index (SII) and the American Spinal Injury Association Impairment Scale (AIS) grade in patients with acute traumatic spinal cord injury (TSCI).METHODS:
We retrospectively investigated 526 patients with acute traumatic spinal cord injury admitted to the First Affiliated Hospital of Nanchang University between January 2012 and December 2021, and for whom routine blood tests were performed within 8 hours of injury. To assess the degree of impairment in TSCI patients using the American Spinal Cord Injury Association Impairment Scale. The patients were divided into 2 groups according to AIS grade as follows patients with an AIS grade of A-B (severe and critical TSCI, respectively) were distinguished from those with an AIS grade of C-E (minimal, mild, and moderate TSCI, respectively). The association between unfavorable outcomes and each indicator was examined separately through univariate logistic regression analysis. Correlations between variables and AIS grades were analyzed by Spearman's correlation test. The discriminative ability of predictive models was evaluated using the area under the curve.RESULTS:
The NLR, PLR, and SII were elevated in patients with spinal cord injury and exceeded the reference values in 95% of cases. The AIS grades were inversely correlated with the NLR, PLR, and SII. In the receiver operating characteristic curve analysis performed to confirm the utility of the NLR, PLR, and SII for predicting the AIS grade, the area under the curve values were 0.710 (95% confidence interval [CI], 0.666-0.755), 0.603 (95% CI, 0.554-0.651) and 0.638 (95% CI, 0.591-0.685), respectively. The optimal cut-off value for the NLR was 0.361 (sensitivity = 0.79, specificity = 0.57).CONCLUSIONS:
The analysis of changes in NLR, PLR, and SII as indicators of the novel systemic inflammatory can be an important complement to traditional methods for the assessment of severity and prognosis and the possible selection of patients for close monitoring. And, NLR showed higher diagnostic performance than PLR and SII.Palabras clave
