Abstract
Jordan and Palestine are tightly related countries as the same families live in the two adjacent countries. The present study sought to examine the prevalence and determinants of Post-Traumatic Stress Disorder (PTSD)symptoms, insomnia, and fatigue among a cohort of People with Epilepsy (PWE) in Jordan. This is a cross-sectional study with inclusion criteria. PTSD, insomnia, and fatigue were assessed using validated scales. Data were analyzed from 109 PWE, PTSD symptoms were screened in (35.5 %), and Insomnia was screened in 51.8 %, moreover, fatigue mean score ± SD was 44.64 ± 26.96. PTSD symptoms were significantly associated with "females" and "age above 30 years" Insomnia severity was associated with "females". Also, the regression results demonstrated that "abstinence from social media" was significantly related to lower insomnia severity. Higher fatigue severity was associated with "married" and "Generalized Tonic-Clonic Seizures", whereas, lower fatigue severity was associated with "males", and with "levetiracetam". Our findings indicate the need for actions to alleviate mental health deterioration in PWE.

Abstract
INTRODUCTION Severe traumatic brain injury (TBI) increases the risk of early posttraumatic seizures (EPTS). Guidelines suggest the use of prophylactic antiseizure agents, including levetiracetam. This study aims to evaluate the feasibility of using levetiracetam dosing based on Glasgow Comas Scale (GCS) scores with higher doses used for more severe TBI. METHODS Patients 6 months to 18 years old admitted to Penn State Hershey Children's Hospital (PSHCH) with a TBI who received levetiracetam for EPTS prophylaxis with at least one documented GCS score were included. Patients were divided into two cohorts: before and after implementation of the pediatric TBI Cerner PowerPlan at PSHCH which standardized levetiracetam dosing based on GCS scores. Primary outcome was appropriate dosing of levetiracetam based on GCS. Secondary outcomes included seizure occurrence and adverse effects. RESULTS Eighty-five patients were included: 42 in the pre-PowerPlan group and 43 in the post-PowerPlan group. Overall, 46 (54%) patients received the appropriate levetiracetam dose based on GCS (pre-PowerPlan, n = 19 [45%] vs. post-PowerPlan n = 27 [63%], p = 0.104). Sixty-four percent of severe TBI patients received appropriate levetiracetam dosing after implantation of the PowerPlan compared with 28% prior to the PowerPlan (p = 0.039). Three patients in each group experienced a seizure while on levetiracetam. Two patients experienced agitation and somnolence attributed to levetiracetam. CONCLUSION Levetiracetam dosing based on GCS scores in pediatric TBI patients is a novel approach, and dosing accuracy may be increased with use of a PowerPlan. Additional large-scale studies are needed to evaluate efficacy and safety of this approach prior to widespread implementation.

Abstract
OBJECTIVE The purpose of this article is to familiarize the reader with the spectrum of neurologic and medical complications relevant to the care of patients with neurologic cancer while highlighting best practices to prevent morbidity and mortality. Topics include tumor-related epilepsy, vasogenic edema, complications of corticosteroid use, disruption of the hypothalamic-pituitary axis, venous thromboembolism, and opportunistic infection. LATEST DEVELOPMENTS In 2021, a joint guideline from the Society for Neuro-Oncology and the European Association of Neuro-Oncology reaffirmed recommendations first established in 2000 that patients with newly diagnosed brain tumors should not be prescribed an antiseizure medication prophylactically. For those with tumor-related epilepsy, monotherapy with a non-enzyme-inducing anticonvulsant is the preferred initial treatment, and levetiracetam remains the preferred first choice. Surveys of physician practice continue to demonstrate excessive use of glucocorticoids in the management of patients with both primary and metastatic central nervous system malignancy. This is particularly concerning among patients who require checkpoint inhibitors as the efficacy of these agents is blunted by concomitant glucocorticoid use, resulting in a reduction in overall survival. Finally, direct oral anticoagulants have been shown to be safe in patients with brain tumors and are now favored as first-line treatment among those who require treatment for venous thromboembolism. ESSENTIAL POINTS Medical care for patients impacted by primary and secondary central nervous system malignancy is complex and requires a committed team-based approach that routinely calls upon the expertise of physicians across multiple fields. Neurologists have an important role to play and should be familiar with the spectrum of complications impacting these patients as well as the latest recommendations for management.

Abstract
Epilepsy is a chronic neurological disease characterized by the presence of spontaneous seizures, with a higher incidence in the pediatric population. Anti-seizure medication (ASM) may produce adverse drug reactions (ADRs) with an elevated frequency and a high severity. Thus, the objective of the present study was to analyze, through intensive pharmacovigilance over 112 months, the ADRs produced by valproic acid (VPA), oxcarbazepine (OXC), phenytoin (PHT), and levetiracetam (LEV), among others, administered to monotherapy or polytherapy for Mexican hospitalized pediatric epilepsy patients. A total of 1034 patients were interviewed; 315 met the inclusion criteria, 211 patients presented ADRs, and 104 did not. A total of 548 ASM-ADRs were identified, and VPA, LEV, and PHT were the main culprit drugs. The most frequent ADRs were drowsiness, irritability, and thrombocytopenia, and the main systems affected were hematologic, nervous, and dermatologic. LEV and OXC caused more nonsevere ADRs, and PHT caused more severe ADRs. The risk analysis showed an association between belonging to the younger groups and polytherapy with ADR presence and between polytherapy and malnutrition with severe ADRs. In addition, most of the severe ADRs were preventable, and most of the nonsevere ADRs were nonpreventable.

Abstract
OBJECTIVE Cognitive impairment is a potential drawback of antiseizure medications. This study aimed to evaluate the impact of different levetiracetam drug regimens on cognitive function. METHODS A retrospective analysis identified 221 patients diagnosed with seizures who underwent cognitive screening. Patients were categorized into four groups: no medications, non-levetiracetam medications, high and low dose levetiracetam. Composite scores determined low and high levetiracetam groups whereby one point was added for each increment in dosage, duration since uptake, and concurrent anti-seizure medication. Variables known to affect cognition were recorded and classified as demographic, seizure-related, diagnosis-related, and psychopathology. Logistic regression was used to identify variables associated with cognitive scores below cut-off. RESULTS Multivariable analysis found being male, non-active in the community, less than 12 years of education, left temporal lobe epilepsy, high seizure frequency, and depression were associated with poor cognitive performance. In a final regression analysis, the high levetiracetam group exhibited a 4.5-fold higher likelihood of scoring below cut-off than the medication-free group (OR 4.5, CI 1.5-13.6, p<.08). Depression (OR 2.1, CI 1.1-3.9, p<.03), being male (OR 2.2, CI 1.1-4.3, p<.02), and not being active in the community (OR 3.8, 1.6-8.7, p <.003) remained significant contributors to the model. Language (p<.05), attention (p<.05), and delayed recall (p<.001) were the most affected cognitive domains. SIGNIFICANCE When taken in small doses, for brief periods as monotherapy, levetiracetam minimally influences cognition. At higher doses, as part of long-term seizure management, in conjunction with multiple ASMs, LEV is associated with cognitive impairment.

A 5-Year Study of Antiseizure Medications (ASMs) Monitoring in Patients with Neuropsychiatric Disorders in an Italian Clinical Center. Pharmaceuticals (Basel) 2023; 16:945. [PMID: 37513857 PMCID: PMC10383891 DOI: 10.3390/ph16070945] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Revised: 06/23/2023] [Accepted: 06/27/2023] [Indexed: 07/30/2023] Open
Abstract
Despite receiving appropriate antiseizure medications (ASMs), a relevant percentage of neuropsychiatric patients do not benefit from this approach, and one reason is subtherapeutic ASMs plasma concentration (C(p)) due to improper drug adherence, interindividual pharmacokinetic differences, or metabolic interactions among different drugs. For these reasons, therapeutic drug monitoring (TDM) by measuring ASMs C(p) is an effective tool that improves pharmacological therapies in clinical practice. Based on these premises, in the present real-world study, we analyzed the C(p) of the most used ASMs in diverse medical conditions, which were assayed during the years 2018-2022 at the University Hospital of Pisa, including about 24,000 samples. This population was largely heterogeneous, and our database did not contain clinical information about the patients. The most used ASMs were Valproate (VPA: 54.5%) and Levetiracetam (LEV: 18.6%), followed by Oxcarbazepine (OxCBZ: 8.3%) and Carbamazepine (CBZ: 7.2%), whereas the associations LEV/VPA, Ethosuximide (ESM)/VPA, and CBZ/VPA were the most frequently proposed. In about 2/3 of assays, ASMs C(p) was in range, except for VPA, which was underdosed in almost half of the samples. Importantly, toxic levels of ASMs C(p) were found very rarely. For VPA, there was a decrease of mean C(p) across ages, from adolescents to older patients, while the C(p) of LEV, CBZ, OxCBZ, and Topiramate (TPM) showed a slight tendency to increase. When we compared females and males, we found that for VPA, the average age was higher for females, whereas women taking Lamotrigine (LTG) and OxCBZ were younger than men. Then, comparing ASMs used in neurologic and psychiatric disorders, based on the request form, it emerged that the mean C(p) of CBZ, OxCBZ, and LTG on samples collected in the Psychiatric Unit was lower compared to the Neurology and Child Neuropsychiatry Units. Finally, the ASMs subjected to multiple dosing starting from an initial subtherapeutic C(p) increased their level at different time points within a year, reaching the reference range for some of them. In conclusion, the present study suggests that TDM is widely applied to monitor ASMs C(p), finding many of them within the reference range, as a demonstration of its utility in clinical practice.

Abstract
PURPOSE To investigate the safety of perampanel in different disorders and doses. METHODS Embase, the Cochrane Library, Medline, and ClinicalTrials.gov were searched from inception to July 2022 for randomized controlled trials (RCTs). The meta-analysis was performed by using Review Manager 5.3 and R 4.2.1 software. RESULTS A total of 17 RCTs with 5711 subjects were included in the final analysis. The double-blind treatment phase was from 12 weeks to 48 weeks. Our results showed that 11 adverse events (aggression, ataxia, balance disorder, dizziness, fall, fatigue, irritability, rash, somnolence, vertigo, and weight increase) were statistically significantly associated with perampanel, and 4 of them (ataxia, dizziness, fatigue, and somnolence) showed a clear dose-response relationship. Psychiatric adverse events occurred most frequently among serious treatment-emergent adverse events (TEAEs). At 8 mg/day, seven adverse events (aggression, balance disorder, dizziness, fatigue, irritability, vertigo, and weight increase) occurred more frequently in patients with epilepsy than in patients with other disorders, whereas dose discontinuation rates due to adverse events were lower in patients with epilepsy than in patients with other disorders. CONCLUSION The safety profile of perampanel is dependent on diseases and dose. The risk of adverse events was statistically significantly higher, with doses exceeding 4 mg/day. Despite a higher risk of adverse events, patients with epilepsy had a lower perampanel discontinuation rate than patients with other disorders.

Abstract
BACKGROUND Levetiracetam, a widely used anticonvulsant drug in children and adolescents, has been associated with irritability, psychosocial symptoms, and low quality of life, which are also influenced by other epilepsy variables. PURPOSE The objective of this study was to investigate the level of treatment-related irritability in adolescents receiving levetiracetam, and to evaluate the relationship between irritability levels and psychosocial symptoms, and quality of life. METHODS A cross-sectional, case-control study was conducted. Consecutive adolescent patients with epilepsy aged 11-17 years with partial or generalized seizures, treated with either levetiracetam or valproic acid for at least 6 months, and healthy controls were recruited. The Affective Reactivity Index parent report and self-report, Strengths and Difficulties Questionnaire, and Pediatric Quality of Life Inventory-Psychosocial subscale were utilized to assess irritability, psychosocial symptoms, and functioning. RESULTS A total of 120 participants were analyzed; 33 patients in the LEV group, 45 patients in the VPA group, and 42 healthy controls. Both self and parent report irritability levels of the LEV group were found to be significantly higher than those of healthy controls. The irritability levels of the LEV and VPA groups were not statistically different, but still the LEV group had higher irritability levels on both scales. In the LEV group, irritability was positively correlated with behavioral, emotional, and attention/hyperactivity problems, and also negatively correlated with psychosocial quality of life. CONCLUSION Adolescents with epilepsy using LEV have a high level of irritability and this is associated with some psychosocial symptoms and poor quality of life.

Abstract
The developmental and epileptic encephalopathies encompass a group of rare syndromes characterised by severe drug-resistant epilepsy with onset in childhood and significant neurodevelopmental comorbidities. The latter include intellectual disability, developmental delay, behavioural problems including attention-deficit hyperactivity disorder and autism spectrum disorder, psychiatric problems including anxiety and depression, speech impairment and sleep problems. Classical examples of developmental and epileptic encephalopathies include Dravet syndrome, Lennox-Gastaut syndrome and tuberous sclerosis complex. The mainstay of treatment is with multiple anti-seizure medications (ASMs); however, the ASMs themselves can be associated with psychobehavioural adverse events, and effects (negative or positive) on cognition and sleep. We have performed a targeted literature review of ASMs commonly used in the treatment of developmental and epileptic encephalopathies to discuss the latest evidence on their effects on behaviour, mood, cognition, sedation and sleep. The ASMs include valproate (VPA), clobazam, topiramate (TPM), cannabidiol (CBD), fenfluramine (FFA), levetiracetam (LEV), brivaracetam (BRV), zonisamide (ZNS), perampanel (PER), ethosuximide, stiripentol, lamotrigine (LTG), rufinamide, vigabatrin, lacosamide (LCM) and everolimus. Bromide, felbamate and other sodium channel ASMs are discussed briefly. Overall, the current evidence suggest that LEV, PER and to a lesser extent BRV are associated with psychobehavioural adverse events including aggressiveness and irritability; TPM and to a lesser extent ZNS are associated with language impairment and cognitive dulling/memory problems. Patients with a history of behavioural and psychiatric comorbidities may be more at risk of developing psychobehavioural adverse events. Topiramate and ZNS may be associated with negative effects in some aspects of cognition; CBD, FFA, LEV, BRV and LTG may have some positive effects, while the remaining ASMs do not appear to have a detrimental effect. All the ASMs are associated with sedation to a certain extent, which is pronounced during uptitration. Cannabidiol, PER and pregabalin may be associated with improvements in sleep, LTG is associated with insomnia, while VPA, TPM, LEV, ZNS and LCM do not appear to have detrimental effects. There was variability in the extent of evidence for each ASM: for many first-generation and some second-generation ASMs, there is scant documented evidence; however, their extensive use suggests favourable tolerability and safety (e.g. VPA); second-generation and some third-generation ASMs tend to have the most robust evidence documented over several years of use (TPM, LEV, PER, ZNS, BRV), while evidence is still being generated for newer ASMs such as CBD and FFA. Finally, we discuss how a variety of factors can affect mood, behaviour and cognition, and untangling the associations between the effects of the underlying syndrome and those of the ASMs can be challenging. In particular, there is enormous heterogeneity in cognitive, behavioural and developmental impairments that is complex and can change naturally over time; there is a lack of standardised instruments for evaluating these outcomes in developmental and epileptic encephalopathies, with a reliance on subjective evaluations by proxy (caregivers); and treatment regimes are complex involving multiple ASMs as well as other drugs.

Abstract
INTRODUCTION Levetiracetam (LEV) is one of the most widely used anti-seizure medications (ASMs) in clinical practice. This is due both to a different mechanism of action when compared to other ASMs and its easy handling. Indeed, because of its interesting pharmacokinetic properties, it is often used outside of the labelled indications, notably in the neurocritical setting as prophylaxis of epileptic seizures. AREAS COVERED A literature search was conducted and the most relevant studies on the pharmacokinetic properties of LEV were selected by two independent investigators. Current evidence on the use of ASM prophylaxis in the neurocritical setting was also reviewed, highlighting and discussing the strengths and limits of LEV as drug of choice for anti-epileptic prophylaxis in this scenario. EXPERT OPINION LEV has a "near-ideal" pharmacokinetic profile, which makes it an attractive drug for ASM prophylaxis in neurocritical care. However, current recommendations restrict ASMs prophylaxis to very selected circumstances and the role of LEV is marginal. Moreover, studies are generally designed to compare LEV versus phenytoin, whereas studies comparing LEV versus placebo are lacking. Further randomized trials will be needed to better elucidate LEV utility and its neuroprotective role in the neurocritical setting.

A pharmacogenomic assessment of psychiatric adverse drug reactions to levetiracetam. Epilepsia 2022; 63:1563-1570. [PMID: 35298028 PMCID: PMC9321556 DOI: 10.1111/epi.17228] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Revised: 03/14/2022] [Accepted: 03/14/2022] [Indexed: 11/17/2022]
Abstract
OBJECTIVE Levetiracetam (LEV) is an effective antiseizure medicine, but 10%-20% of people treated with LEV report psychiatric side-effects, and up to 1% may have psychotic episodes. Pharmacogenomic predictors of these adverse drug reactions (ADRs) have yet to be identified. We sought to determine the contribution of both common and rare genetic variation to psychiatric and behavioral ADRs associated with LEV. METHODS This case-control study compared cases of LEV-associated behavioral disorder (n = 149) or psychotic reaction (n = 37) to LEV-exposed people with no history of psychiatric ADRs (n = 920). All samples were of European ancestry. We performed genome-wide association study (GWAS) analysis comparing those with LEV ADRs to controls. We estimated the polygenic risk scores (PRS) for schizophrenia and compared cases with LEV-associated psychotic reaction to controls. Rare variant burden analysis was performed using exome sequence data of cases with psychotic reactions (n = 18) and controls (n = 122). RESULTS Univariate GWAS found no significant associations with either LEV-associated behavioural disorder or LEV-psychotic reaction. PRS analysis showed that cases of LEV-associated psychotic reaction had an increased PRS for schizophrenia relative to contr ols (p = .0097, estimate = .4886). The rare-variant analysis found no evidence of an increased burden of rare genetic variants in people who had experienced LEV-associated psychotic reaction relative to controls. SIGNIFICANCE The polygenic burden for schizophrenia is a risk factor for LEV-associated psychotic reaction. To assess the clinical utility of PRS as a predictor, it should be tested in an independent and ideally prospective cohort. Larger sample sizes are required for the identification of significant univariate common genetic signals or rare genetic signals associated with psychiatric LEV ADRs.

Abstract
Valproic acid (VPA) and levetiracetam (LEV) are used in epilepsy treatment. However, their use to treat short-bowel syndrome has not been reported. We herein report a 68-year-old man who was hospitalized for symptomatic epilepsy following cerebral infarction. He had a history of superior mesenteric arterial occlusion, and only 30 cm of his jejunum was intact. VPA and LEV were administered, and good blood levels were achieved at clinical doses. This suggests that the gastrointestinal tract absorption of LEV and VPA is good even in patients with short-bowel syndrome and a 30-cm jejunum.

Abstract
Epilepsy is a chronic disease that affects millions of people worldwide. Antiepileptic drugs (AEDs) are used to control seizures. Even though parts of their mechanisms of action are known, there are still components that need to be studied. Therefore, the search for novel drugs, new molecular targets, and a better understanding of the mechanisms of action of existing drugs is still crucial. Levetiracetam (LEV) is an AED that has been shown to be effective in seizure control and is well-tolerable, with a novel mechanism of action through an interaction with the synaptic vesicle protein 2A (SV2A). Moreover, LEV has other molecular targets that involve calcium homeostasis, the GABAergic system, and AMPA receptors among others, that might be integrated into a single mechanism of action that could explain the antiepileptogenic, anti-inflammatory, neuroprotective, and antioxidant properties of LEV. This puts it as a possible multitarget drug with clinical applications other than for epilepsy. According to the above, the objective of this work was to carry out a comprehensive and integrative review of LEV in relation to its clinical uses, structural properties, therapeutical targets, and different molecular, genetic, and systemic action mechanisms in order to consider LEV as a candidate for drug repurposing.

Abstract
Excessive daytime sleepiness (EDS) and attentional deficits are often observed in people with epilepsy. They may be the consequence of seizures and subclinical discharges as well as of comorbid conditions as obstructive sleep apnea/hypopnea syndrome (OSAS), attention deficit hyperactivity disorder (ADHD), or other less frequent disorders. Excessive daytime sleepiness may also be caused or worsened by antiseizure medications (ASMs). Several meta-analyses suggested that lamotrigine, lacosamide, and perhaps eslicarbazepine are less sedative than other traditional and new ASMs and, in patients prone to somnolence, might be preferred over ASMs with more sedative properties. In patients with severe EDS and/or ADHD, advantages and risks of a treatment with a psychostimulant need to be considered. Methylphenidate, modafinil, armodafinil, pitolisant, and solriamfetol are authorized for use in ADHD and EDS in patients with narcolepsy and some of them also in OSAS. These agents are off-label for the treatment of EDS associated with epilepsy. They do not have proconvulsant effects, although there are several possible risks for patients with epilepsy. The risks of cardiovascular events and psychiatric symptoms should be carefully evaluated as such disorders can coexist with epilepsy and be triggered by these agents. Finally, combination of psychostimulants with ASMs may be associated with several pharmacokinetic drug-drug interactions.

Abstract
OBJECTIVE To evaluate the efficacy and safety of levetiracetam (LEV) in comparison to phenytoin (PHT) as second line antiseizure medication (ASM) for Pediatric convulsive status epilepticus (SE). DATA SOURCE PubMed, Embase, Google scholar/Google, Scopus, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Database of Systematic Reviews and Cochrane Central Register of Controlled Trials. STUDY SELECTION Randomized controlled trials (RCTs) assessing LEV and PHT as second line agent for convulsive SE in children <18 years published between 1 January 2000 and 30 November 2020. DATA EXTRACTION The data were pooled regarding the proportion of children achieving seizure cessation within 5-60 min of completion of study drug infusion (primary outcome); and seizure cessation within 5 min, time to achieve seizure cessation, seizure recurrence between 1 to 24 h, intubation and cardiovascular instability (secondary outcomes). Data were analyzed using RevMan version 5.4 and quality analysis was done using Cochrane risk-of-bias tool. The study protocol was registered with PROSPERO. DATA SYNTHESIS Twelve RCTs with 2293 children were included. Seizure cessation within 5-60 min was similar with both the drugs [82% in LEV vs. 77.5% in PHT, risk ratio (RR) = 1.04, 95% confidence interval (95% CI) 0.97-1.11, p = 0.30]. Seizure recurrences within 1-24 h was higher with PHT in comparison to LEV (16.6% vs. 9.7%, RR = 0.63, 95% CI 0.44-0.90, p = 0.01). Higher proportion of children in PHT group required intubation and mechanical ventilation (21.4% vs. 14.2%, RR = 0.54, 95% CI 0.30-0.98, p = 0.04). Seizure cessation within 5 min, time to achieve seizure cessation, and cardiovascular instability were similar with both the drugs. Three RCTs were at low risk of bias and nine were at high risk of bias. CONCLUSION The efficacy of LEV is similar to PHT as second line ASM for Pediatric convulsive SE. Seizure recurrences between 1 to24 h and requirement of intubation and mechanical ventilation were significantly higher with PHT in comparison to LEV.

Abstract
OBJECTIVE Studies of the effect of valproate (VPA) on the background EEG have shown varying results. Therefore, we compared the effect of VPA and levetiracetam (LEV) on the EEG alpha peak frequency (APF). METHODS We retrospectively examined the APF in resting-state EEG of patients undergoing inpatient video-EEG monitoring (VEM) during withdrawal of VPA or LEV. We assessed APF trends by computing linear fits across individual patients' APF as a function of consecutive days, and correlated the APF and daily antiseizure medication (ASM) doses on a single-patient and group level. RESULTS The APF in the VPA-group significantly increased over days with falling VPA doses (p = 0.005, n = 13), but did not change significantly in the LEV-group (p = 0.47, n = 18). APF correlated negatively with daily ASM doses in the VPA-group (average of r = -0.74 ± 0.12 across patients, p = 0.0039), but not in the LEV-group (average of r = -0.17 ± 0.18 across patients, p = 0.4072). CONCLUSIONS Our results suggest that VPA treatment slows the APF. This APF reduction correlates with the daily dose of VPA and is not present in LEV treatment. SIGNIFICANCE Our study identifies a VPA-related slowing of the APF even in patients without electroencephalographic or overt clinical signs of encephalopathy.

Abstract
PURPOSE Aggression-irritability is the most commonly encountered antiepileptic-drug-induced psychiatric adverse effects. In this cross-sectional study, we tried to assess antiepileptic-drug-induced aggression in patients with epilepsy (PWE) with a standardized rating scale. METHODS Two hundred sixty-six consecutive outpatients receiving treatment for epilepsy with antiepileptic drugs (AEDs) were initially examined, and the effects of the investigated drugs in regard to aggression were investigated using the Buss-Perry Aggression Questionnaire (BAQ). We compared BAQ scores as a function of a specific class of AEDs, levetiracetam (LEV), lacosamaide (LCM), perampanel (PER), and carbamazepine (CBZ), and determined whether AED type had a relationship with aggression. Additionally, the association of BAQ score with other clinico-demographic variables was also assessed. RESULTS One-way ANOVA revealed that the LEV group had a significantly higher mean BAQ score as compared to the CBZ (P = 0.001) and LCM (P = 0.029) groups for total score. In subscale analysis, the LEV group had higher scores than the CBZ group for the physical aggression (p = 0.01), verbal aggression (p = 0.02) and hostility (p = 0.01) subscales, while the LEV group had a significantly higher mean score than the LCM group for hostility (p = 0.025). In multiple regression analysis, LEV had a statistically significant impact on increased total BAQ score (B = 0.119, p = 0.049). In contrast, CBZ (B = -0.191, p = 0.002), older age at epilepsy onset (B = -0.269, p = 0.000) and female gender (B = -0.210, p = 0.000) had a significant association with lower total BAQ score. CONCLUSIONS Our results indicate that LEV is associated with increased aggression, while CBZ and LCM showed effects to reduce aggression.

Abstract
PURPOSE Although levetiracetam (LEV) is globally established as a leading antiseizure medication (ASM) it is still a controversial matter whether dose increases correspond with an increased efficacy if LEV in the recommended dose range did not show satisfying efficacy. In our clinical perception we questioned the value of dose increases in such non-responders. METHODS In this retrospective monocenter study we analyzed the data of adult people with epilepsies (PWE) with focal-onset seizures who had been treated at the department of adults of the Kork Epilepsy Center between 2009 and 2019, who had been on a stable daily LEV dose and in whom LEV was further increased due to further seizures in spite of baseline LEV in a recommended daily dose range. For reasons of data homogeneity, we included only PWE with at least two definite seizures during the hospital stay under the baseline LEV dose who were treated and observed as in-patients after the increase of LEV for a period at least three-fold longer than the baseline interval before. Additional data acquisition comprised clinical data including adverse events, serum concentrations of LEV and other ASMs, and additional laboratory findings. The primary outcome variable was the change of seizure frequency prior to and after the increase of LEV. RESULTS Out of 518 PWE who had been on LEV during their hospital stay, a total of 61 PWE fulfilled the inclusion criteria. After a gradual dose increment, 91,8 % of PWE showed a reduced seizure frequency, 73,8 % had a reduction of seizures of 50 % or more, and 21,3 % were seizure-free during the observation period. A significant seizure reduction could be shown with a seizure count of 2,5/week prior to the increment and 0,7/week after dose increment (p < 0,00001). Seven PWE reported minor adverse events and ten PWE showed slight laboratory changes (within normal levels). CONCLUSION Contrary to our long-term clinical impression, LEV dose increments were reasonable and improved the seizure situation in PWE, usually without additional safety hazards.

Abstract
BACKGROUND AND OBJECTIVE The optimal choice for first- and second-line antiseizure medications for pediatric patients with convulsive status epilepticus remains ambiguous. The present study aimed to estimate the comparative effect on the efficacy and safety of different antiseizure medications in pediatric patients with status epilepticus and provide evidence for clinical practice. METHODS We searched PubMed, EMBASE, and the Cochrane Library for eligible randomized controlled trials. Inclusion criteria included: (1) pediatric patients; (2) diagnosis of status epilepticus; and (3) randomized controlled trials. Exclusion criteria were: (1) mixed population without a pediatric subgroup analysis; (2) not status epilepticus; (3) received the study drug prior to admission; (4) sample size fewer than 30; and (5) not randomized controlled trials. Primary outcome was seizure cessation. Secondary outcomes were seizure recurrence within 24 h, respiratory depression, and admission to an intensive care unit. The hierarchy of competing antiseizure medications was presented using the surface under the cumulative ranking curve. RESULTS Eight first-line antiseizure medication studies involving 1686 participants and eight second-line antiseizure medication studies involving 1711 participants were eligible for analysis. Midazolam, diazepam, lorazepam, and paraldehyde were administered as first-line antiseizure medications. Valproate, phenobarbital, phenytoin, fosphenytoin, and levetiracetam were investigated as second-line antiseizure medications. No significant differences were observed across first- and second-line antiseizure medications. Midazolam ranked the best for primary and secondary outcomes among the first-line antiseizure medications. Phenobarbital ranked the best for seizure cessation and a lower risk of admission to the intensive care unit. Valproate had superiority in preventing recurrence within 24 h. Levetiracetam had the lowest probability of developing respiratory depression. CONCLUSIONS This study demonstrated the hierarchy of competing interventions. Midazolam could be a better option for first-line treatment. Phenobarbital, levetiracetam, and valproate had their respective superiority in the second-line intervention. This study may provide useful information for clinical decision making under different circumstances.

Behavioral alterations associated with levetiracetam in pediatric epilepsy. Epilepsy Behav 2020; 112:107472.

Abstract
Levetiracetam (LEV) has an improved pharmacological profile and is one of the most commonly used antiepileptic drugs (AEDs). However, associations between this pharmacological profile and behavioral side effects have been extensively reported in pediatric populations. We assessed behavioral changes after initiation of LEV, prescribed by the treating neurologist, in Chilean patients with epilepsy aged 4-15 years. A behavioral questionnaire was applied at baseline and at two, four, and twelve weeks of treatment. Thirty patients were enrolled: 16 males, 14 females, average age 8 years (range: 4-14). By week four, 23.3% of patients showed significant behavioral alterations that persisted throughout the observation period. No significant alterations emerged after four weeks in the remaining patients. Family history of psychiatric disease and prior behavioral difficulties were predisposing factors for adverse behavioral effects. Although previous studies associated adverse behavioral effects with LEV in pediatric patients with epilepsy, we believe that this is the first study to use a prospective methodology and standardized tools to quantify the symptomatology. Adverse behavioral effects may significantly affect quality of life for patients and families, diminishing the tolerability of treatment. To ensure successful therapy and improve medical decision-making, it is essential to consider predisposing factors for drug-related adverse effects and to regularly assess for behavioral alterations during treatment.

Levetiracetam Induced Behavioral Abnormalities in a Patient with Seizure Disorder: A Diagnostic Challenge. Case Rep Psychiatry 2020; 2020:8883802. [PMID: 32908767 PMCID: PMC7450317 DOI: 10.1155/2020/8883802] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Revised: 08/03/2020] [Accepted: 08/10/2020] [Indexed: 11/18/2022] Open
Abstract
Levetiracetam is a second-generation antiepileptic drug that is chemically unrelated to other antiepileptic drugs. Levetiracetam is a broad-spectrum antiseizure medication that is approved as an adjunctive therapy in the treatment of partial and generalized tonic-clonic seizures in children and adults with epilepsy. The mechanism by which Levetiracetam induces behavioral changes remains unknown. Its proposed mechanism of action involves binding to synaptic vesicle protein 2A (SV2A) and this leads to neuronal inhibition. Though, the drug has a convenient dosing regimen and is relatively well tolerated, neuropsychiatric side effects can emerge beyond the initial titration period and may be the most common reason for drug discontinuation. Levetiracetam has been reported to cause varying degrees of psychiatric adverse effects including behavioral disturbance such as agitation, hostility and psychosis, and mood symptoms and suicidality. It has been shown to induce psychiatric side effects in 13.3% of adults, with only 0.7% presenting with severe symptoms such as depression, agitation, or hostility. The prevalence rate of development of psychosis in these patients is estimated to be about 1.4%. A review of literature has demonstrated a relative correlation between Levetiracetam use and the development of neurobehavioral symptoms which is increased in predisposed individuals. This research describes the case of a 28-year-old woman with seizure disorder and a psychiatric history of schizoaffective disorder who developed aggressive behavior, paranoia, and severe hostility following administration of Levetiracetam 750 mg orally twice daily. She developed acute behavioral symptoms which were reversed with cessation of Levetiracetam. This report emphasizes the need for developing an appropriately high index of suspicion in promoting surveillance and prompt identification of behavioral adverse effects associated with Levetiracetam especially in high-risk patient population.

Abstract
OBJECTIVES Liver transplant is currently the most effective option for patients with end-stage liver disease. Seizures are the most common neurologic complication after liver transplant. Posterior reversible encephalopathy syndrome is a neurologic syndrome characterized by lethargy, seizures, visual disturbances, and radiologic findings of edema in the posterior regions of the cerebral hemispheres. Levetiracetam is prescribed for a broad spectrum of seizure types but does not have a specific indication for epilepsy in children after solid-organ transplant. Our aim was to investigate the efficacy and tolerability of levetiracetam in pediatric transplant recipients with posterior reversible encephalopathy syndrome and epilepsy. MATERIALS AND METHODS We reviewed records of patients treated for epilepsy due to posterior reversible encephalopathy syndrome after liver transplant seen at our pediatric neurology clinic between January 2010 and March 2019. Patients were assessed clinically and by neurologic examination, electroencephalography, and cerebral magnetic resonance imaging. RESULTS Among 134 children who had undergone liver transplant between 2010 and 2019, 10 patients (6 males, 4 females; age range,7-19 y) who were diag-nosed with posterior reversible encephalopathy syndrome and epilepsy were included in the study. All patients received levetiracetam at 20 mg/kg/day. After a mean follow-up of 28.9 months (range, 24-40 mo), 9 patients (90%) attained complete seizure freedom. One patient who had an underlying neurodegenerative disease (hemophagocytic syndrome) other than posterior reversible encephalopathy syndrome continued to have seizures under levetiracetam treatment. One patient had a mild adverse reaction (irritability) due to levetiracetam but did not require drug discontinuation. CONCLUSIONS In this study, 90% of patients with posterior reversible encephalopathy syndrome became seizure free with levetiracetam treatment. Our findings suggest that levetiracetam has a favorable efficacy for epilepsy due to posterior reversible encephalopathy syndrome in pediatric liver transplant recipients with tolerable adverse effects.

Abstract
A 62-year-old previously healthy male was admitted with new onset generalised tonic-clonic seizures. Treatment was initiated with the antiepileptic levetiracetam and he had no further episodes of seizures. Creatine kinase (CPK) level was 1812 IU/L 12-hour postadmission. Despite good hydration, his CPK levels continued to rise dramatically and reached a level of 19 000 IU/L on day 5. This rise was unexplained as he did not have any further seizures and had a normal renal function. In the absence of other risk factors, the rare possibility of levetiracetam being responsible for the disproportionately high CPK was considered. Within 12 hours of withdrawal of levetiracetam, there was a downward trend in the CPK levels, with a 10-fold decrease in CPK levels over the next 4 days. This is only the ninth case reported in literature regarding this rare and potentially serious adverse effect of levetiracetam.

Abstract
INTRODUCTION Benign epilepsy with centrotemporal spikes (BECTS) is a common epileptic syndrome in childhood, characterized by brief and infrequent partial motor seizures, with or without generalization and mostly recurring during sleep. Because of its favorable efficacy, tolerability, and safety profile, levetiracetam (LEV) monotherapy is often administered in these patients. Long-term effects of LEV therapy and its influence on cognitive functions remain controversial. PURPOSE This evaluated the changes in the cognitive profile of children with BECTS treated with LEV monotherapy for 2 years, compared with a control group of children with specific learning disabilities. METHOD Our patient cohort included 20 children aged 8-14 years diagnosed as having BECTS and administered LEV monotherapy and 10 age/sex-matched controls with specific learning disabilities. All participants underwent a standardized test for assessing cognitive profile (Wechsler Intelligence Scale for Children - Fourth Edition [WISC-IV]) before drug therapy and after 2 years of treatment. Average LEV blood level and electroencephalographic (EEG) recordings were periodically monitored. Several factors such as age, sex, response to therapy, and EEG pattern changes were considered. Statistical analysis was performed using Student's t-test for paired and independent samples. p < 0.05 was considered statistically significant. RESULTS Children administered LEV for 24 months showed a mild but statistically significant improvement in overall cognitive abilities. Verbal skills, visual-perceptual reasoning, working memory, and processing speed showed slight but significant improvement. In the control group, cognitive profile remained substantially unchanged at 2-year follow-up. CONCLUSIONS Not only do our data suggest a nonworsening of the cognitive profile in BECTS with LEV but, on the contrary, cognitive scores also improved over time, unlike the control group.

Abstract
PURPOSE The purpose of this analysis is to assess the effect of antiepileptics (AEDs) on seizure prevention and short and long term functional outcomes in patients with acute intracerebral hemorrhage. METHOD The meta-analysis was conducted using the PRISMA guidelines. A literature search was performed of the PubMed, the Cochrane Library, and EMBASE databases. Search terms included "Anticonvulsants", "Intracerebral Hemorrhage", and related subject headings. Articles were screened and included if they were full-text and in English. Articles that did not perform multivariate regression were not included. Overall effect size was evaluated with forest plots and publication bias was assessed with the Begg's and Egger's tests. RESULTS A total of 3912 articles were identified during the initial review. After screening, 54 articles remained for full review and 6 articles were included in the final analysis. No significant association between the use of AEDs after ICH and functional outcome (OR 1.53 [95%CI: 0.81-2.88] P = 0.18, I2 = 81.7%). Only one study evaluated the effect AEDs had in preventing post-ICH seizures. CONCLUSIONS The use of prophylactic AEDs was not associated with improved short and long outcomes after acute ICH. This analysis supports the 2015 AHA/ASA recommendation against prophylactic AEDs (class III; level of evidence b).

Abstract
INTRODUCTION Epilepsy is a chronic and debilitating neurological disease, with a peak of incidence in the first years of life. Today, the vast armamentarium of antiepileptic drugs (AEDs) available make even more challenging to select the most appropriate AED and establish the most effective dosing regimen. In fact, AEDs pharmacokinetics is under the influence of important age-related factors which cannot be ignored. Areas covered: Physiological changes occurring during development age (different body composition, immature metabolic patterns, reduced renal activity) can significantly modify the pharmacokinetic profile of AEDs (adsorption, volume of distribution, half-life, clearance), leading to an altered treatment response. We reviewed the main pharmacokinetic characteristics of AEDs used in children, focusing on age-related factors which are of relevance when treating this patient population. Expert opinion: To deal with this pharmacokinetic variability, physicians have at their disposal two tools: 1) therapeutic drug concentration monitoring, which may help to set the optimal therapeutic regimen for each patient and to monitor eventual fluctuation, and 2) the use of extended-release drug formulations, when available. In the next future, the development of 'ad-hoc' electronic dashboard systems will represent relevant decision-support tools making the AED therapy even more individualized and precise, especially in children.

Abstract
Excitotoxicity contributes to epileptogenesis after severe traumatic brain injury (sTBI). Demographic and clinical risk factors for post-traumatic seizures (PTS) have been identified, but genetic risk remains largely unknown. Thus, we investigated whether genetic variation in astroglial glutamate transporter genes is associated with accelerated epileptogenesis and PTS risk after sTBI. Adults (n = 267) 18-75 years old were assessed over a three-year period post-TBI. Single nucleotide polymorphisms (SNPs) throughout the SLC1A2 and SLC1A3 genes were assayed. Kaplan-Meier estimates and log-rank statistics were used to compare seizure frequencies by genotype. Multivariate Cox proportional hazards regression was used to estimate hazard ratios (HRs) for genotypes significant in Kaplan-Meier analyses. Thirty-nine tagging SNPs were examined (SLC1A2: n = 21, SLC1A3: n = 18). PTS developed in 57 (21.4%) individuals. Of those with PTS, n = 20 (35.7%) had an immediate/early seizure within the first seven days, and n = 36 (64.3%) had a late seizure occurring between eight days and three years post-TBI. When adjusting for multiple comparisons, rs4869682 genotypes (SLC1A3, GG vs. T-carriers) were associated with time to first seizure (p = 0.003). Median time until first seizure was 20.4 days for individuals with a GG genotype and 44.8 days for T-carriers. After adjusting for covariates, rs4869682 GG-homozygotes had a 2.05 times increased PTS risk versus T-carriers (aHR = 2.08, 95% confidence interval: 1.20, 3.62, p = 0.009). Variation within SLC1A3 is associated with accelerated epileptogenesis and clinical PTS development after sTBI. Future studies should validate these findings and examine how genetic variation at rs4869682 may be a target for PTS prevention and treatment.

Abstract
OBJECTIVE There is limited literature on cognitive, behaviour and sleep-related adverse effects of levetiracetam and oxcarbazepine among adult epilepsy patients, except for what is available from the initial efficacy trials. This study was initiated with the aim to evaluate the incidence and prevalence of various cognitive, behaviour and sleep-related adverse effects of levetiracetam versus oxcarbazepine among people with epilepsy. METHODS The study was conducted in two parts: part A was a cross-sectional study, and part B was a longitudinal study. Trail making test A & B, digit symbol substitution test, Stroop colour and word test, controlled oral word association test and PGI memory scale, Neuropsychiatric Inventory, sleep log and ESS-I were used for assessment of cognitive, behaviour and sleep-related adverse effects. RESULTS In the cross-sectional as well as prospective study, no significant difference was observed in the cognitive performance of patients in levetiracetam and oxcarbazepine group in any of the cognitive assessment. Among 120 patients enrolled in the cross-sectional study, significantly higher number of patients in the levetiracetam group compared to the oxcarbazepine group,had agitation/aggression (20% vs10%, p = 0.047) and irritability (26.7% vs 3.3%, p = 0.007).Among 132 patients enrolled in the prospective study, significantly higher increase in the domain score of agitation/aggression (14.5% vs 1.6%, p = 0.028) and irritability (17.7% vs 1.6%, p = 0.018) was observed in the levetiracetam group compared to oxcarbazepine group. A significantly higher proportion of patients in the oxcarbazepine group had hypersomnolence (11.3% vs 1.6%, p = 0.026), as compared to the levetiracetam group. SIGNIFICANCE On cross-sectional as well as on longitudinal assessment, nearly one-fifth of patients on levetiracetam have behaviour related adverse effects, with dose modification required for half among these. Nearly 11% of patients on oxcarbazepine reported sleep-related adverse effects (higher total sleep duration per 24 h).

Abstract
Juvenile myoclonic epilepsy (JME) constitutes about 10% of all epilepsies. Because of executive dysfunction, people with JME may be prone to impulsivity and risk-taking behavior. Our aim was to investigate whether psychosocial issues associated with impulsivity are more prominent in people with JME than in those with other types of genetic generalized epilepsy (GGE). Patients with GGE were recruited retrospectively through the Drammen Hospital records in Buskerud County, Norway, 1999-2013. They were invited to a semi-structured interview, either at the hospital or at home. Ninety-two patients with JME and 45 with other types of GGE were interviewed. Variables were evaluated in terms of their association with JME versus other GGE diagnosis using a logistic regression model. Juvenile myoclonic epilepsy was associated with use of illicit recreational drugs and police charges, although with borderline significance (odds ratio [OR] 3.4, p = 0.087 and OR 4.2, p = 0.095); JME was also associated with being examined for attention-deficit hyperactivity disorder (ADHD) in females (OR 15.5, p = 0.015), a biological parent with challenges like addiction or violent behavior (OR 3.5, p = 0.032), and use of levetiracetam (OR 5.1, p = 0.014). After controlling for group differences, we found psychosocial complications to be associated with JME, potentially influencing the lives of the individuals and their families to a greater extent than the seizures per se. Thus, JME should be considered a disorder of the brain in a broader sense than a condition with seizures only.

Abstract
OBJECTIVE To evaluate the efficacy, safety and economics of levetiracetam (LEV) for epilepsy. MATERIALS AND METHODS PubMed, Scopus, the Cochrane Library, OpenGrey.eu and ClinicalTrials.gov were searched for systematic reviews (SRs), meta-analyses, randomized controlled trials (RCTs), observational studies, case reports and economic studies published from January 2007 to April 2018. We used a bubble plot to graphically display information of included studies and conducted meta-analyses to quantitatively synthesize the evidence. RESULTS A total of 14,803 records were obtained. We included 30 SRs/meta-analyses, 34 RCTs, 18 observational studies, 58 case reports and 2 economic studies after the screening process. The included SRs enrolled patients with pediatric epilepsy, epilepsy in pregnancy, focal epilepsy, generalized epilepsy and refractory focal epilepsy. Meta-analysis of the included RCTs indicated that LEV was as effective as carbamazepine (CBZ; treatment for 6 months: 58.9% vs 64.8%, OR=0.76, 95% CI: 0.50-1.16; 12 months: 54.9% vs 55.5%, OR=1.24, 95% CI: 0.79-1.93), oxcarbazepine (57.7% vs 59.8%, OR=1.34, 95% CI: 0.34-5.23), phenobarbital (50.0% vs 50.9%, OR=1.20, 95% CI: 0.51-2.82) and lamotrigine (LTG; 61.5% vs 57.7%, OR=1.22, 95% CI: 0.90-1.66). SRs and observational studies indicated a low malformation rate and intrauterine death rate for pregnant women, as well as low risk of cognitive side effects. But psychiatric and behavioral side effects could not be ruled out. LEV decreased discontinuation due to adverse events compared with CBZ (OR=0.52, 95% CI: 0.41-0.65), while no difference was found when LEV was compared with placebo and LTG. Two cost-effectiveness evaluations for refractory epilepsy with decision-tree model showed US$ 76.18 per seizure-free day gained in Canada and US$ 44 per seizure-free day gained in Korea. CONCLUSION LEV is as effective as CBZ, oxcarbazepine, phenobarbital and LTG and has an advantage for pregnant women and in cognitive functions. Limited evidence supports its cost-effectiveness.

Abstract
OBJECTIVE Assessment of the relevance between serum drug concentration to its therapeutic response is a valid monitoring strategy for the clinical efficacy of antiepileptic drugs (AEDs). Levetiracetam (LEV) is a broad spectrum AED with a possible anti-inflammatory effect. We aimed to determine the relationship between LEV concentrations and its therapeutic response, and the effect of LEV on IL1-beta concentrations in patients with epilepsy. METHODS Patients on monotherapy (n = 7) or polytherapy (n = 15) with LEV for their seizures management were included. Blood samples of each patient were collected: just before LEV intake, 1 h, 2 h, 4 h and 8 h following the last dose. Serum LEV concentrations were measured by liquid chromatography mass spectrometry and IL1-beta concentrations by chemiluminescent immunometric assay. Concentration to dose (C/D) ratio values was used for analyses. LEV concentrations were compared between responders (≤1 seizure/month) and non-responders (>1 seizure/month) and patients with or without adverse reactions. IL1-beta concentrations before and at 2 h following LEV ingestion were compared in order to detect the effect of the increase in serum LEV concentration on IL1-beta. RESULTS Although there was no change in LEV (C/D) ratio or LEV maximum concentration (Cmax)/D ratio of the responders and non-responders, the C/D ratio following 1 h of LEV intake (2.17 ± 0.59 kg.day/L) and Cmax/D ratio (2.25 ± 0.56 kg.day/L) in the patients with adverse effects was significantly higher than for the patients without adverse effects (1.09 ± 0.12 kg.day/L and 1.49 ± 0.14 kg.day/L respectively). A statistically significant decrease was found in the IL1-beta concentration to LEV (C/D) ratio with the increase in LEV concentration in patients on LEV monotherapy. CONCLUSION The possible relationship between LEV Cmax and its therapeutic response or IL1-beta concentrations may be an importance indication of LEV antiepileptic efficacy. Consequently, monitoring LEV Cmax values may enhance LEV adherence because patients would be less likely to develop adverse effects.

Acute antiepileptic drug use in intensive care units. J Neurol 2018; 265:2841-2850.

Abstract
BACKGROUND In intensive care units (ICUs), antiepileptic drugs (AEDs) are used for manifold indications. This is the first study to assess the prevalence of acute AED use in ICUs and to identify associated clinical variables. METHODS All patients in seven adult ICUs of a German university hospital in 2016 were retrospectively evaluated. Data were extracted from the computerized critical care information system and manually reviewed. Acute AED treatments were defined as initiated during ICU treatment or ≤ 6 h before ICU admission, excluding benzodiazepines and sedatives. RESULTS Among 2335 patients evaluated, 8.8% received acutely started AEDs: 5.1% due to epileptic seizures, mostly acute symptomatic, and 3.7% for other indications like pain, post-hypoxic myoclonus, and singultus. Following multivariable analyses, acute AED use was independently associated with intracranial reasons for ICU admission and long durations of ICU stay, but not with increased disease severity scores or mortality. Levetiracetam was the substance most frequently used to treat epileptic seizures (88%) as was pregabalin for other conditions (49%). Among surviving patients, acute AEDs were continued beyond ICU discharge in 86% if seizure-related and in 78% if not seizure-related, even if there was no evident need for long-term AED treatment. CONCLUSIONS One out of eleven ICU patients receives acute AEDs, in almost half of cases for non-seizure indications. Acute AED use is a marker for intracranial ICU indications and prolonged ICU treatments. Usually, newer-generation AEDs are employed with favourable pharmacokinetic and safety profiles. However, whenever possible, acutely started AED should be discontinued before discharge from ICU.

Abstract
OBJECTIVES Prophylactic levetiracetam is currently used in ~40% of patients with intracerebral hemorrhage, and the potential impact of levetircetam on health-related quality of life is unknown. We tested the hypothesis that prophylactic levetiracetam is independently associated with differences in cognitive function health-related quality of life. DESIGN Patients with intracerebral hemorrhage were enrolled in a prospective cohort study. We performed mixed models for T-scores of health-related quality of life, referenced to the U.S. population at 50 ± 10, accounting for severity of injury and time to follow-up. SETTING Academic medical center. PATIENTS One-hundred forty-two survivors of intracerebral hemorrhage. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS T-scores of Neuro-Quality of Life Cognitive Function v2.0 was the primary outcome, whereas Neuro-Quality of Life Mobility v1.0 and modified Rankin Scale (a global functional scale) were secondary measures. We prospectively documented if prophylactic levetiracetam was administered and retrieved administration data from the electronic health record. Patients who received prophylactic levetiracetam had worse cognitive function health-related quality of life (T-score 5.1 points lower; p = 0.01) after adjustment for age (p = 0.3), National Institutes of Health Stroke Scale (p < 0.000001), lobar hematoma (p = 0.9), and time of assessment; statistical models controlling for prophylactic levetiracetam and the Intracerebral Hemorrhage Score, a global measure of intracerebral hemorrhage severity, yielded similar results. Lower T-scores of cognitive function health-related quality of life at 3 months were correlated with more total levetiracetam dosage (p = 0.01) and more administered doses of levetiracetam in the hospital (p = 0.03). Patients who received prophylactic levetiracetam were more likely to have a lobar hematoma (27/38 vs 19/104; p < 0.001), undergo electroencephalography monitoring (15/38 vs 21/104; p = 0.02), but not more likely to have clinical seizures (4/38 vs 7/104; p = 0.5). Levetiracetam was not independently associated with the modified Rankin Scale scores or mobility health-related quality of life (p > 0.1). CONCLUSIONS Prophylactic levetiracetam was independently associated with lower cognitive function health-related quality of life at follow-up after intracerebral hemorrhage.

Abstract
Levetiracetam (LEV) is effective for focal and generalized epilepsy and is used worldwide because of its relatively few drug interactions and favorable tolerability. However, some psychiatric adverse events (PAEs) have been reported, resulting in drug withdrawal. The pathophysiology of LEV-induced PAE has not yet been elucidated. In this study, we investigated the relationship between PAEs and human leukocyte antigen (HLA) genes. Eleven epilepsy patients, who developed PAEs after the administration of LEV and spontaneously improved after drug withdrawal, were enrolled retrospectively. Genomic DNA from the peripheral blood was extracted, and four-digit allele genotyping of HLA genes was performed. The genotype frequencies of HLA genes were compared to those of 80 patients in which LEV was well tolerated, as well as to 485 individuals from the general Korean population. The frequency of the HLA-A*1101 allele was significantly higher in the LEV-induced PAEs group compared to both the LEV-tolerant group (p = 0.021, OR 4.80, 95% CI 1.30-17.74) and the general Korean population (p = 0.015, OR 4.62, 95% CI 1.38-15.45). This study is the first attempt at investigating the relationship between the HLA system and LEV-induced PAE. The results of this study suggest that the HLA-A*1101 allele could be a risk factor for the development of PAEs.

Abstract
Anti-epileptic drugs (AEDs) have had a major impact on children, improving their quality of life and significantly reducing both morbidity and mortality. They are, however, associated with significant toxicity. Behavioural problems and somnolence are the most frequent adverse drug reactions for many AEDs. Unfortunately, the comparative risk of drug toxicity for different AEDs has been inadequately studied. Drug toxicity is poorly reported in randomised controlled trials. Prospective cohort studies are the best way to study drug toxicity. There have been a few prospective cohort studies of children with epilepsy, but the numbers of children have been small. Systemic reviews of the toxicity of individual AEDs have been helpful in identifying the risk of drug toxicity. Parents of children with epilepsy and the children and young people who are due to receive AED treatment have the right to know the likelihood of them experiencing drug toxicity. Unfortunately, the evidence base on which health professionals can provide such information is limited.

Abstract
OBJECTIVE To describe a serious adverse event as a result of rapid intravenous injection of undiluted levetiracetam in a dog. CASE SUMMARY An 8-year-old female spayed Chihuahua was evaluated for cluster seizures and tachypnea. The patient was administered an intravenous dose of undiluted levetiracetam (60 mg/kg) and immediately developed tachycardia, hyperglycemia, hypotension, and a dull mentation. The patient's blood pressure and mentation did not respond to intravenous fluid boluses but improved immediately after administration of epinephrine intravenously. The patient subsequently developed respiratory failure necessitating mechanical ventilation, prior to cardiac arrest. Necropsy examination noted a pulmonary inflammatory cell infiltrate, pulmonary edema, and interstitial pneumonia. NEW OR UNIQUE INFORMATION PROVIDED This report documents a serious adverse event associated with intravenous levetiracetam administration to a dog.

Abstract
PURPOSE Psychiatric and behavioral side effects (PBSEs) are common, undesirable effects associated with antiepileptic drug (AED) use. The objective of the study was to compare the PBSE profiles of older and newer AEDs in a large specialty practice-based sample of patients diagnosed with epilepsy. METHODS As part of the Columbia and Yale AED Database Project, we reviewed patient records including demographics, medical history, AED use, and side effects for 4085 adult patients (age: 18 years) newly started on an AED regimen. Psychiatric and behavioral side effects were determined by patient or physician report in the medical record, which included depressive mood, psychosis, anxiety, suicidal thoughts, irritability, aggression, and tantrum. Significant non-AED predictors of PBSE rate were first determined from 83 variables using logistic regression. Predictors were then controlled for in the comparison analysis of the rate of PBSEs and intolerable PBSEs (PBSEs that led to dosage reduction or discontinuation) between 18 AEDs. RESULTS Psychiatric and behavioral side effects occurred in 17.2% of patients and led to intolerability in 13.8% of patients. History of psychiatric condition(s), secondary generalized seizures, absence seizures, and intractable epilepsy were associated with increased incidence of PBSE. Levetiracetam (LEV) had the greatest PBSE rate (22.1%). This was statistically significant when compared with the aggregate of the other AEDs (P<0.001, OR=6.87). Levetiracetam was also significantly (P<0.001) associated with higher intolerability rate (17.7%), dose decreased rate (9.4%), and complete cessation rate (8.3%), when compared with the aggregate of the other AEDs. Zonisamide (ZNS) was also significantly associated with a higher rate of PBSE (9.7%) and IPBSE (7.9%, all P<0.001). On the other hand, carbamazepine (CBZ), clobazam (CLB), gabapentin (GBP), lamotrigine (LTG), oxcarbazepine (OXC), phenytoin (PHT), and valproate (VPA) were significantly associated with a decreased PBSE rates (P<0.001). Carbamazepine, GBP, LTG, PHT, and VPA were also associated with lower IPBSE rates when compared individually with the aggregate of other AEDs. All other AEDs were found to have intermediate rates that were not either increased or decreased compared with other AEDs. When each AED was compared to LTG, only CBZ had a significantly lower PBSE rate. The main limitations of this study were that the study design was retrospective and not blinded, and the AEDs were not randomly assigned to patients. CONCLUSIONS Psychiatric and behavioral side effects occur more frequently in patients taking LEV and ZNS than any other AED and led to higher rates of intolerability. Lower PBSE rates were seen in patients taking CBZ, CLB, GBP, LTG, OXC, PHT, and VPA. Our findings may help facilitate the AED selection process.

Neuropsychiatric adverse events of antiepileptic drugs in brain tumour-related epilepsy: an Italian multicentre prospective observational study. Eur J Neurol 2017; 24:1283-1289.

Abstract
BACKGROUND AND PURPOSE We assessed the prevalence and magnitude of neuropsychiatric adverse events (NPAEs) associated with antiepileptic drugs (AEDs) among patients with brain tumour-related epilepsy (BTRE). METHODS This observational, prospective, multicentre study enrolled 259 patients with BTRE after neurosurgery. All patients received AED monotherapy. Efficacy was assessed through clinical diaries, whereas NPAEs were collected using the Neuropsychiatric Inventory Test-12 questionnaire at baseline and after 5 months. RESULTS Tumour localization in the frontal lobe was associated with a higher prevalence of NPAEs (odds ratio, 7.73; P < 0.001). Independent of tumour localization, levetiracetam (LVT) treatment was associated with higher prevalence and magnitude of NPAEs (odds ratio, 7.94; P < 0.01) compared with other AEDs. Patients with oligodendroglioma reported more NPAEs than patients with other tumour types. NPAEs were not influenced by chemotherapy, radiotherapy or steroid treatment. Evaluating non-neurobehavioural adverse events of AEDs, no significant differences were found among AEDs, although patients treated with old AEDs had a higher prevalence of adverse events than those treated with new AEDs. CONCLUSIONS Both tumour localization in the frontal lobe and LVT treatment are associated with a higher risk of NPAEs in patients with BTRE. LVT is regarded as a first-line option in patients with BTRE because of easy titration and few significant drug-to-drug interactions. Thus, as NPAEs lead to poor compliance and a high dropout rate, clinicians need to accurately monitor NPAEs after AED prescription, especially in patients with frontal lobe tumours receiving LVT.

Abstract
The aim of this study was to evaluate the risk factors, clinical implications, and prognosis of new-onset seizures that occurred after pediatric liver transplantation, and to assess the efficacy of levetiracetam treatment. The clinical and laboratory data of liver transplanted 28 children who had seizures after liver transplantation and specifically of 18 children who received levetiracetam were analyzed retrospectively. Sixteen patients (88.9%) remained seizure-free and in 2 (11.1%), more than 50% reduction in seizures were detected with levetiracetam treatment. In conclusion, seizures are generally the most common complication by a spectrum of seizure types, and sometimes cause symptomatic epilepsy. The most common risk factors for seizures in transplant recipients is immunosuppressant toxicity. Currently, there isn't a specific treatment involving the transplant patient population. Levetiracetam may be preferable in pediatric patients as it's reliable for liver disease and has advantages in the treatment of postoperative seizures due to its intravenous usage.

Abstract
AIMS Experimental studies show that some antiepileptic drugs (AEDs) may modify natural immune defences, thus influencing the risk of developing infectious diseases. The aim of this meta-analysis was to explore whether AEDs as a class of drugs or singularly may increase risk of infectious diseases. METHODS A meta-analysis of all randomized, double-blind, placebo-controlled trials (RCTs) investigating any AED in any condition was performed. All terms that could be coded in the System Organ Classes (SOCs) of infections and infestations using the Medical Dictionary for Regulatory Activities were recorded. Additional subanalyses were performed also pooling together AEDs sharing similar mechanisms of action. RESULTS Two hundreds and sixty-nine double-blind, placebo-controlled studies were identified and, among them, 127 RCTs with 16 AEDs (brivaracetam, gabapentin, lacosamide, levetiracetam, lamotrigine, oxcarbazepine, perampanel, pregabalin, phenytoin, remacemide, retigabine, rufinamide, tiagabine, topiramate, valproate, zonisamide) reported at least one of 19 symptoms or diseases that could be included in the Medical Dictionary for Regulatory Activities SOC term infections and infestations. These terms were singularly recorded and then pooled together in the SOC term infection and infestation. Topiramate was significantly associated with an increased risk of infection (risk difference = 0.04; 95% confidence interval = 0.01/0.06), while oxcarbazepine was significantly associated with a lower risk (-0.005; -0.09/-0.01). Risk difference of all studies with all AEDs showed a slight, but significantly increased risk of infection (0.01; 0.00/0.002). Levetiracetam and brivaracetam RCTs, when pooled together, were associated with a significantly increased risk of infection (0.03; 0.01/0.05). CONCLUSIONS Some AEDs are associated with a mild increased risk of infection.
