Coronavirus Disease 2019 (COVID-19) Associated With Febrile Status Epilepticus in a Child

Purpose. There is a lack of knowledge on consecutive patients with epilepsy associated with bilateral hippocampal sclerosis (BHS). We aimed to investigate the differentiating features of BHS in comparison with unilateral HS (UHS). Method. We investigated our database for patients with epilepsy fulfilling the major magnetic resonance imaging criteria for BHS; namely, presence of bilateral atrophy and high signal changes on T2 and FLAIR series in the hippocampi. UHS patients seen in past 2 years were included as the control group. Clinical, EEG, and other laboratory findings, data on treatment response and epilepsy surgery were investigated from their files. Results. A total of 124 patients (31 with BHS and 93 with UHS; 49 right-sided and 44 left-sided) were included. We found that 16.1% of the BHS and 18.3% of the UHS groups were not drug-refractory. A binary logistic regression analysis performed with significant clinical features disclosed that history of febrile status epilepticus, mental retardation, and status epilepticus were statistically more common in BHS group. Moreover, diagnosis of psychosis established by an experienced psychiatrist and slowing of the EEG background activity were both found significantly more frequent in BHS. 66.67% of the operated BHS patients showed benefit from epilepsy surgery. Conclusions. BHS is a heterogeneous group, showing significant differences such as increased frequencies of mental retardation, status epilepticus, febrile status epilepticus and psychosis, in comparison to UHS. In all, 16.1% of the BHS cases showed a benign course similar to the UHS group and some patients with drug-resistant epilepsy may show benefit from epilepsy surgery.

Febrile Status Epilepticus

Background: Risk factors identification associated with status epilepticus is valuable in order to prevent morbidity and mortality in children. This study aimed to consider the etiology, risk factors, morbidity and mortality in children with status epilepticus. Methods: This retrospective cross-sectional study was performed on 119 patients aged from one month old to 15 years old. Patients’ data were recorded, including basic demographic, etiology and clinical information. The different risk factors correlated to morbidity and mortality were evaluated in this study. Results: The most common etiologies were acute symptomatic and febrile status epilepticus by 32.8% and 22.7%, respectively. Abnormal brain imaging results were reported far more frequently in patients with a history of neurodevelopmental delay and previous status epilepticus (p<0.001). The overall morbidity and mortality rates were 18.9% and 10.9%, respectively; while these rates in patients with delayed development (45.16% and 18.42%, respectively) were significantly higher than patients with normal development (8% and 7.4%, respectively). The morbidity rates in patients with previous seizures and previous status epilepticus were remarkably higher than those without previous history of seizure (26.41% vs 11.32%; p=0.047) and without previous status epilepticus (36.36% versus 14.28%; p=0.018). The length of hospital stay in patients with mortality was considerably longer than patients without mortality (12.30 ± 16.1 days vs 7.29 ± 6.24 days; p=0.033). The mortality rate in patients with normal Lumbar Puncture result was notably lower than those with abnormal LP result (2.9% vs 50%). The morbidity rate in patients with abnormal brain imaging results (p<0.001) was significantly greater than those in patients with normal results. The mortality rate was relatively higher in patients with abnormal imaging results compared to those normal results. Etiology was an important predictor of mortality and morbidity rates; acute symptomatic (32.8%), febrile status epilepticus (22.7%) and remote symptomatic (16.8%) etiologies were the most common underlying causes of S.E. While in children less than 3 years old, the acute symptomatic etiology and febrile status epilepticus etiologies were estimated as the most common, in most patients older than 3 years old the most common etiology of status epilepticus was unknown. Congenital brain defects etiology had the highest mortality (36.36%) and morbidity (42.85%) rate. The lowest morbidity (3.84%) and mortality (0%) rates were for patients with febrile status epilepticus etiology. Conclusion: Age, developmental delay, history of previous status epilepticus, the length of hospital stay, abnormal brain imaging results and the underlying etiology of status epilepticus were associated with increased morbidity and mortality among children with status epilepticus.
