Development of a Risk Prediction Model for Acute Necrotizing Encephalopathy in Children With Influenza A Virus Infection
To investigate the clinical characteristics,laboratory findings,and prognosis of acute necrotizing encephalopathy(ANE) in children with influenza A virus infection,and to develop a risk prediction model for ANE occurrence.
Methods
2
A retrospective analysis was performed for 92 children from January to December 2023,among whom 40 had influenza alone and 52 had influenza with complications (34 with influenza-associated encephalopathy [IAE] and 18 with acute necrotizing encephalopathy[ANE]). Clinical features,laboratory markers,and prognosis were compared between groups,and multivariable logistic regression analysis was used to identify independent risk factors,and the receiver operating characteristic(ROC) curve was used to evaluate the predictive performance of the model.
Results
2
No significant differences were observed among the uncomplicated influenza,IAE,and ANE groups in age,sex,or peak body temperature(all
P
>
0.05),whereas mental status differed significantly among the three groups(
P
<
0.001). White blood cell count (WBC),platelet count(PLT),C-reactive protein(CRP),and lactate differed significantly between the ANE and IAE groups(
P
<
0.05 or
P
<
0.001). The ANE group had a low recovery rate and a high mortality rate,whereas all patients in the IAE group recovered without death. Multivariable logistic regression analysis identified WBC,PLT,CRP,and lactate as independent predictors for ANE. The prediction model based on these variables yielded an area under the curve (AUC) of 0.940,indicating good discriminative ability.
Conclusion
2
Children with influenza A virus infection complicated by ANE exhibit distinct clinical and laboratory features and have a poor prognosis. The prediction model based on routine hematological,inflammatory,and metabolic indicators demonstrated good performance in identifying children at high risk for ANE in this cohort,providing a useful reference for early clinical intervention. However,its generalizability still requires further validation in multicenter studies.
