    Clinical characteristics of severe influenza as a risk factor for febrile seizures in children: a retrospective analysis by Peng Li, Peng Li, Mei Chen, Mei Chen, Daobin Wang, Xue Zhang, Ruiyang Sun, Wanyu Jia, Shuqin Fu, Junhao Cui, Chunlan Song, Chunlan Song

    Published 2024-10-01
    “…The predictive efficacy was evaluated by receiver operating characteristic (ROC) curve analysis.Results(1) Multiple logistic regression analysis revealed that C-reactive protein (CRP) levels, Serum interleukin 6 (IL-6) levels, Days from onset of Flu symptoms to hospitalization, cerebrospinal fluid protein (CSF-TP) levels and the influenza virus type A (FluA) infection rate were found to be independent risk factors for severe influenza combined with febrile seizures in children. (2) ROC curve analysis showed that the cut-off value of CRP, Serum IL-6, Days from onset of Flu symptoms to hospitalization and CSF-TP were 7.57 mg/L, 9.84 pg/ml, 4.5 days and 194.8 mg/L, respectively.ConclusionChildren with severe influenza with CRP ≥ 7.57 mg/L, Serum IL-6 ≥ 9.84 pg/ml, Days from onset of Flu symptoms to hospitalization ≤4.5 days, CSF-TP ≥ 194.8 mg/L and FluA had a significantly increased risk of febrile seizures. …”
