ABSTRACT: Objective: A case-control study of Influenza-Associated Necrotizing Encephalopathy (IANE) in children was conducted to explore the risk factors for the diagnosis of IANE, and to provide a predictive reference for the diagnosis of IANE. Methods: The children with IANE who received treatment in our hospital from January 2016 to December 2020 were selected as the study group, and the children with Influenza-Associated Encephalopathy (IAE) group who received treatment in the same period were selected as the control group. The blood biochemical, coagulation function and cerebrospinal fluid test results of the two groups were analyzed by univariate analysis. Receiver Operating Characteristic curve (ROC) analysis was used to determine the optimal threshold point of each index for the indicators with statistically significant differences in univariate analysis results, and multivariate Logistic stepwise regression analysis was performed according to the optimal threshold points. Results: In the IANE group, there were 32 children, including 20 males and 12 females, aged 60 (35, 84) months. There were 40 children in IAE group, including 26 males and 14 females, aged 58 (23, 97) months. Univariate results showed that serum Lactate Dehydrogenase (LDH), Cerebrospinal Fluid Lactate Dehydrogenase (CSF LDH) and Cerebrospinal Fluid Protein (CSF PRO) in the IANE group were significantly higher than those in the IAE group, and the difference between the two groups was statistically significant (P 535 U/L (OR = 31.264, 95% CI: 5.892 - 165.878, P 0.49 g/L (OR = 7.695, 95% CI: 1.052 - 56.305, P = 0.044) were independent risk factors for IANE. Conclusion: For children with influenza whose neurological symptoms appear rapidly and persist in the early stages of the disease, blood LDH > 535 U/L and CSF PRO > 0.49 g/L are independent risk factors for IANE.
