Objectives: To identify factors that predict the occurrence of seizures in patients with aneurysmal subarachnoid hemorrhage (SAH) and to evaluate the efficacy of antiepileptic drugs (AEDs) in preventing in-hospital seizures among patients who undergo clip occlusion of ruptured intracranial aneurysms. Methods: In this retrospective study, the medical charts of 205 patients admitted for aneurysmal SAH in Philippine General Hospital (PGH) and who underwent craniotomy and clipping of aneurysm from January 2011 to June 2014 were reviewed. Demographic, radiologic, and clinical factors were converted into categorical variables and their association with the occurrence of seizures analyzed. The incidence of seizures among patients who received an AED (AED cohort) and those who did not receive an AED (No AED cohort) were compared. Secondarily, the effects of seizures and AED use on early postoperative outcomes were determined using the Glasgow Outcome Scale (GOS) on the day of discharge. Results: Among 205 patients with aneurysmal SAH, 31 (15.1%) developed seizures. 21 (10.2%) had seizures at onset of SAH and only seven (3.4%) had in-hospital seizures. Aneurysm re-rupture (OR 5.26, p-value 0.045) and the presence of a parenchymal clot (OR 2.90, p-value 0.043) were independent predictors for seizure occurrence. There was no significant difference in the incidence of seizures in the AED cohort and in the No AED cohort (4/100, 4% vs. 3/99, 3%, p-value 0.714). AED use was associated with a higher proportion of patients with a discharge GOS score of 3 or less (28.0% vs 12.1%, p-value 0.005). Conclusion The results of the study do not support the routine use of AEDs in patients with aneurysmal SAH.

OBJECTIVES: To study the efficacy and safety of domestic generic levetiracetam in replacement of brand-name levetiracetam in the treatment of children with epilepsy. METHODS: A retrospective analysis was performed on the medical data of 154 children with epilepsy who received domestic generic levetiracetam in the inpatient or outpatient service of Guangdong Provincial People's Hospital from May 2019 to December 2020. Domestic generic levetiracetam and brand-name levetiracetam were compared in terms of efficacy and safety. RESULTS: For these 154 children, the epilepsy control rate was 77.3% (119/154) at baseline. At 6 months after switching to domestic generic levetiracetam, the epilepsy control rate reached 83.8% (129/154), which showed a significant increase (P<0.05). There was no significant change in the frequency of seizures from baseline to 6 months after switching (P>0.05). The incidence of refractory epilepsy in children with no response after switching treatment was significantly higher than that in children with response (P<0.05). Before switching, only 1 child (0.6%) experienced somnolence, while after switching, 3 children (1.9%) experienced mild adverse drug reactions, including dizziness, somnolence, irritability, and bad temper. CONCLUSIONS Switching from brand-name to generic levetiracetam is safe and effective and holds promise for clinical application, but more prospective randomized controlled trials are required in future.

OBJECTIVE: To systematically evaluate the efficacy and safety of levetiracetam (LEV) versus phenytoin (PHT) as second-line drugs for the treatment of convulsive status epilepticus (CSE) in children. METHODS: English and Chinese electronic databases were searched for the randomized controlled trials comparing the efficacy and safety of LEV and PHT as second-line drugs for the treatment of childhood CSE. RevMan 5.3 software was used for data analysis. RESULTS: Seven studies with 1 434 children were included. The Meta analysis showed that compared with the PHT group, the LEV group achieved a significantly higher control rate of CSE ( CONCLUSIONS LEV has a better clinical effect than PHT in the treatment of children with CSE and does not increase the incidence rate of adverse events.

Background: Few studies have been published on new-onset geriatric epilepsy especially in older Chinese people. This study was to have a comprehensive understanding of new-onset geriatric epilepsy and find a more reasonable diagnosis and management of epilepsy in older people. Methods: One hundred and three patients with onset age 60 years and older were admitted between January 2008 and December 2016. Electronic medical records were reviewed to collect information. Results: There were 103 older patients with new-onset epilepsy. The mean age of the patients was 68.5 ± 6.4 years (range: 60-89 years), and there were 67 (65%) men and 36 (35%) women. The mean onset age was 67.9 ± 6.2 years (range: 60-89 years). The most common identifiable etiology of symptomatic seizures was autoimmune epilepsy in 43 (41.7%) patients. The second most common etiology was stroke in 15 (14.6%) patients. Seven (6.8%) older patients with acute seizures present with status epilepticus and 26 (25.2%) patients experienced clustered seizures (more than three events in 24 h) at seizure onset. Focal seizures (96.1%) were more common than generalized seizures (3.9%). Fifty-three (51.5%) patients had an abnormal brain magnetic resonance imaging (MRI) scan. Among them, video-electroencephalogram findings in 31 (30.1%) patients correlated with MRI abnormalities. Levetiracetam was the most used drugs before admission, in hospital, and during follow-up. Conclusions Autoimmune encephalitis is becoming an increasing risk factor of subsequent epilepsy in older people. Older patients with new epilepsy are more likely to respond to antiepileptic drugs, and drug-resistant epilepsy is uncommon.

BACKGROUND: Studies on the relationship between antiepileptic drug (AED) administration and clinical outcomes in patients with mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) remain scarce. Levetiracetam (LEV) is an AED that is neuroprotective in various neurologic disorders. This study aimed to determine the impact of LEV on the outcome of MELAS. METHODS: A retrospective, single-center study was performed based on a large cohort of patients with MELAS with a history of seizures (n = 102). Decisions on antiepileptic therapies were made empirically. Patients were followed up for 1 to 8 years (median, 4 years) and divided into 2 groups based on whether LEV was administered (LEV or non-LEV). The modified Rankin scale (mRS) scores and mortality risks were analyzed in all patients. RESULTS: LEV, carbamazepine, benzodiazepines, topiramate, oxcarbazepine, valproate, and lamotrigine were administered in 48, 37, 18, 13, 11, 9, and 9 patients, singly or in combination, respectively. The mean mRS score of the LEV group (n = 48) was lower than that of the non-LEV group (n = 54; mean ± standard deviation, 2.79 ± 1.47 vs. 3.83 ± 1.93, P = 0.006) up to the end of the study. Nevertheless, there was no difference in the proportion of subjects without disability (mRS ranging 0-1) between the groups (P = 0.37). The multivariate regressions revealed that LEV treatment was associated with lower mRS scores (odds ratio 0.32, 95% confidence interval [CI] 0.15-0.68, P = 0.003) and mortality rates (hazard ratio 0.24, 95% CI 0.08-0.74, P = 0.013). There was a significant difference in the Kaplan-Meier survival curves between the groups (χ = 4.29, P = 0.04). CONCLUSIONS The LEV administration is associated with lower mortality in patients with MELAS in this retrospective study. Further laboratory research and prospective cohort studies are needed to confirm whether LEV has neuroprotective effects on patients with mitochondrial diseases.
