Analysis of Adverse Drug Reactions in Pediatric Patients with Epilepsy: An Intensive Pharmacovigilance Study. CHILDREN (BASEL, SWITZERLAND) 2023; 10:1775. [PMID: 38002866 PMCID: PMC10670375 DOI: 10.3390/children10111775] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/08/2023] [Revised: 10/27/2023] [Accepted: 10/30/2023] [Indexed: 11/26/2023]
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
OBJECTIVES Levetiracetam is an anticonvulsive drug increasingly used in paediatric populations. Ontogenesis may alter its pharmacokinetics, demanding dose individualisation of levetiracetam in paediatric populations. We therefore aimed to explore levetiracetam pharmacokinetics and to propose its optimal dosing in the paediatric population. METHODS Individual levetiracetam pharmacokinetic parameters were calculated based on therapeutic drug monitoring data, using a one-compartmental model, and regression models were used to explore possible covariates. RESULTS 56 patients aged from 47 days to 18 years were included in the analysis. The median (IQR) volume of distribution and clearance of levetiracetam were 0.7 (0.58-0.85) L/kg and 0.123 (0.085-0.167) L/hour/kg, respectively. Levetiracetam pharmacokinetics were influenced by postnatal age, body size descriptors and renal functional status. CONCLUSIONS Based on observed relationships, an individualised loading dose of 26.2 mg/kg body weight and maintenance dose of 20.7 mg/mL/min of estimated glomerular filtration rate were calculated as optimal. Since we observed increased levetiracetam clearance in association with valproate co-medication, caution should be used when combining these two drugs.

[PMID: 36878742 DOI: 10.1016/j.braindev.2023.02.007] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Revised: 02/09/2023] [Accepted: 02/13/2023] [Indexed: 03/08/2023]
Abstract
OBJECTIVE Perampanel (PER) is a novel antiepileptic drug. The efficacy, tolerability and safety of PER in children and adolescents with epilepsy are still unclear. We aimed to study the efficacy and safety of PER in children and adolescents with epilepsy. METHODS We searched PubMed, Embase and Cochrane Library for relevant literature up to November 2022. Then we extracted the relevant data from eligible literature for systematic review and meta-analysis. RESULT Twenty-one studies involving 1968 children and adolescent patients were included. A reduction in seizure frequency of at least 50 percent occurred in 51.5% (95% confidence interval [CI] [47.1%, 55.9%]) of patients. Complete seizure cessation occurred in 20.6% (95%CI [16.7%, 25.4%]). The incidence of adverse events was 40.8% (95%CI [33.8%, 48.2%]). The most common adverse events were drowsiness 15.3% (95% CI [13.7%, 16.9%]), irritability 9.3% (95%CI [8.0%, 10.6%]), dizziness 8.4% (95% CI [7.2%, 9.7%]). The incidence of drug discontinuation due to adverse events was 9.2% (95% CI [7.0%, 11.5%]). CONCLUSION PER is generally well tolerated and effective in the treatment of epilepsy in children and adolescents. Larger studies are still needed to explore the application of PER in children and adolescents. RISK OF BIAS AND LIMITATION The funnel plot suggests that there may be publication bias in our meta-analysis, and most of the included studies were Asian, so there may be some racial differences.

Epilepsy Behav 2023; 140:109065. [PMID: 36791631 DOI: 10.1016/j.yebeh.2022.109065] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Revised: 12/17/2022] [Accepted: 12/17/2022] [Indexed: 02/17/2023]
Abstract
BACKGROUND Levetiracetam (LVT), while an effective treatment for multiple seizure types, is associated with a high incidence of neuropsychiatric adverse events (NPAEs). In predominantly retrospective studies, supplementation with pyridoxine/vitamin B6 (PN) was associated with improvement in NPAEs in some people. A previous review highlighted a lack of double-blind, controlled trials of PN for the treatment of NPAEs in individuals treated with LVT. The current paper updates the findings from the previous review to include evidence from studies published since June 2019. METHODS An updated systematic review of the published literature was performed in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, Embase, the Cochrane Library, and Google Scholar were searched to identify studies published between June 2019 and 2nd November 2022 in which supplementary PN was initiated for the treatment of LVT-associated NPAEs. All study types were eligible. The risk of bias in randomized trials was assessed using the Cochrane risk-of-bias tool. RESULTS Seven additional studies were identified: two double-blind, randomized controlled trials (RCTs), four retrospective studies, and one retrospective case series. One RCT reported significant improvements from baseline in behavioral adverse events (BAEs) in both the intervention (PN) group and the low-dose control group (both p < 0.05), with a significantly greater improvement in the intervention group (p < 0.001). In the second RCT, differences in BAE severity between PN and placebo groups at the endpoint were not statistically significant. In one retrospective study, subjective irritability was reported to have improved from baseline in 9/20 individuals (45%) treated with supplementary PN. Data for systematic assessments (PHQ-9 and GAD-7) were available for 10 individuals. Assessment by PHQ-9 showed that six individuals improved, two worsened and two had no change. Based on the GAD-7, three people improved, two worsened and five had no change. In the second retrospective study, 18/41 individuals (44%) who commenced PN following the emergence of BAEs showed "significant" improvement. In a separate group of individuals with pre-existing behavioral problems in whom PN treatment was initiated at the same time as commencing LVT, 3/18 (16.7%) developed BAEs. This compared with 79/458 people (17.2%) who were initially treated only with LVT. The third retrospective study compared treatment-related irritability in individuals who had been treated with both LVT and perampanel, either sequentially or concomitantly. Two people who developed irritability while receiving LVT monotherapy were able to continue treatment with the addition of PN. The fourth study reported a significantly lower LVT discontinuation rate in individuals taking PN and a higher rate of improved behavior in those who were able to continue LVT. The case series reported improvements in behavioral symptoms in six people within two to three weeks of commencing supplementary PN. CONCLUSION Data published within the last three years add to earlier evidence suggesting that PN might be effective in the treatment of NPAEs associated with LVT. However, the quality of evidence remains poor and only a few prospective trials have been published. Data from placebo-controlled trials are still largely lacking. Currently, there is insufficient evidence to justify any firm recommendation for PN supplementation to treat NPAEs associated with LVT. Further well-designed, prospective trials are warranted.

Abstract
Objectives Pharmaceutical allergic reactions due to antiseizure medications (ASMs) are one of the major concerns in the management of patients. Finding an alternative ASM which does not cause allergic reactions and has acceptable effectiveness can be difficult. In this regard, the present study attempts to investigate the cross-reactivity between phenobarbital and levetiracetam in children under treatment for seizure control. Materials & Methods The present study is a prospective, observational independent assessor study. 30 children with epilepsy who were hypersensitive to phenobarbital therapy were studied. In order to evaluate the cross-reactivity of the drugs, levetiracetam replaced phenobarbital to control seizure. Within 6 months, any allergic reactions and seizure recurrences were evaluated in the patients. Results 53 % of the children in this study were female. The mean age of patients was 42.4 months. In patients' follow up no cross-reactive responses were observed in any of the patients. Seizure recurrence rate was 30 % in the first six months of follow up that with increasing dosage in the second six months of follow-up, decreased to 10 %. Conclusion Based on the results of this study, in children with epilepsy controlled by phenobarbital if allergic reactions to phenobarbital occur, levetiracetam may be used as a suitable alternative medicine.

Abstract
Background Febrile-infection related epilepsy syndrome (FIRES) is a rare epilepsy syndrome in which a previously healthy individual develops refractory status epilepticus in the setting of a preceding febrile illness. There are limited data regarding detailed long-term outcomes. This study aims to describe the long-term neuropsychological outcomes in a series of pediatric patients with FIRES. Methods This is a retrospective multi-center case series of pediatric patients with a diagnosis of FIRES treated acutely with anakinra who had neuropsychological testing at least 12 months after status epilepticus onset. Each patient underwent comprehensive neuropsychological evaluation as part of routine clinical care. Additional data collection included the acute seizure presentation, medication exposures, and outcomes. Results There were six patients identified with a median age of 11.08 years (IQR: 8.19-11.23) at status epilepticus onset. Anakinra initiation was a median of 11 days (IQR: 9.25-13.50) after hospital admission. All patients had ongoing seizures and none of the patients returned to baseline cognitive function with a median follow-up of 40 months (IQR 35-51). Of the five patients with serial full-scale IQ testing, three demonstrated a decline in scores over time. Testing results revealed a diffuse pattern of deficits across domains and all patients required special education and/or accommodations for academic learning. Conclusions Despite treatment with anakinra, neuropsychological outcomes in this series of pediatric patients with FIRES demonstrated ongoing diffuse neurocognitive impairment. Future research will need to explore the predictors of long-term neurocognitive outcomes in patients with FIRES and to evaluate if acute treatment interventions improve these outcomes.

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.

CNS Drugs 2022; 36:1079-1111.

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
OBJECTIVES Levetiracetam (LEV) is an anti-seizure medication (ASM) known to have significant behavioral side effects in children with epilepsy. These side effects may be improved by supplemental vitamin B6 (pyridoxine) use. Our research aimed to study risk factors for LEV side effects and the role of vitamin B6 in altering this risk. METHODS We retrospectively analyzed the demographic and clinical profile of all pediatric patients on LEV treatment between July 2019 and December 2020. T-tests, Chi-square and Fisher exact tests were used to assess predictors of LEV discontinuation. A p-value of <0.05 was considered statistically significant. RESULTS 150/240 (62%) children were on additional medications besides LEV for epilepsy management. Thirty-five percent children reported side effects, especially behavioral and mood concerns. Of the patients who reported side effects on LEV, 71% were taking vitamin B6 (n = 59). The rate of LEV discontinuation was significantly lower for children on vitamin B6 than children not taking B6, regardless of monotherapy or polypharmacy (49% v 88% respectively, p = 0.001). Over half of the patients who were able to remain on LEV reported improved behavior with B6 supplementation as compared to those who were unable to continue LEV (17/30, 57% versus 0/26, 0%; p < 0.001). CONCLUSIONS Levetiracetam side effects significantly impact the tolerability of this ASM in children with epilepsy. Our results suggest that vitamin B6 supplementation can significantly reduce the odds of discontinuing LEV due to its behavioral side effects.

Yang C, Yang Y, Peng Y, Zhang L, Yu D. Efficacy and safety of lacosamide in pediatric patients with epilepsy: A systematic review and meta-analysis. Epilepsy Behav 2022; 134:108781. [PMID: 35914435 DOI: 10.1016/j.yebeh.2022.108781] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2022] [Revised: 05/16/2022] [Accepted: 05/30/2022] [Indexed: 02/08/2023]
Abstract
OBJECTIVE Lacosamide (LCM), is a third-generation antiseizure medicine, with limited clinical evidence for use in pediatric populations. We aimed to evaluate evidence for the efficacy and safety of LCM in pediatric patients with epilepsy. METHODS A systematic review was performed using literature published from inception to February 2022 identified in MEDLINE, Embase, Cochrane Library, and four Chinese databases. Efficacy and safety outcome data were collected, and a meta-analysis was performed. RESULT Twenty-one studies involving 1230 pediatric patients were included. The median percent reduction in seizure frequency per 28 days from baseline to maintenance was 33.1% (95% confidence interval [CI] 22.7%, 43.5%). After 6 months of treatment, the 50%, 75%, and 100% responder rates were 53.3% (95% CI 40.7%, 65.9%), 28.3% (95% CI 20.8%, 35.8%), and 20.4% (95% CI 12.6%, 28.2%), respectively. After 12 months of treatment, the 50%, 75%, and 100% responder rates were 42.0% (95% CI 29.5%, 54.5%), 19.5% (95% CI 11.1%, 27.8%), and 15.2% (95% CI 6.6%, 23.8%), respectively. The most common adverse events (AEs) were drowsiness (15.0%), dizziness (9.9%), and somnolence (8.3%). CONCLUSION Lacosamide is generally effective and well tolerated to use in children with epilepsy. However, further research with high-quality data and long-term follow-up of LCM use in pediatric populations is needed.

Abstract
There are numerous potential factors that may affect growth in children with epilepsy, and these must be evaluated in any child with appetite and weight concerns. Antiseizure medications (ASMs) have potential adverse effects, and many may affect appetite, thus impacting normal growth and weight gain. The aim of this review is to focus on the impact of both epilepsy and ASMs on appetite and weight in children. We systematically reviewed studies using Medline assessing the impact of ASMs on appetite and weight in children. Eligible studies included randomized controlled trials and open-label studies (open-label extension and interventional) that targeted or included the pediatric population (0-18 years of age). Each study was classified using the American Academy of Neurology (AAN) Classification of Evidence for Therapeutic Studies, and the level of evidence for impact on appetite and weight in children was graded. ASMs associated with decreased appetite and/or weight loss include fenfluramine, topiramate, zonisamide, felbamate, rufinamide, stiripentol, cannabidiol, brivaracetam and ethosuximide; ASMs with minimal impact on weight and appetite in children include oxcarbazepine, eslicarbazepine, lamotrigine, levetiracetam, lacosamide, carbamazepine, vigabatrin and clobazam. The ASM most robustly associated with increased appetite and/or weight gain is valproic acid; however, both pregabalin and perampanel may also lead to modest weight gain or increased appetite in children. Certain ASMs may impact both appetite and weight, which may lead to increased morbidity of the underlying disease and impaired adherence to the treatment regimen.

Abstract
Aims This multicenter, open‐label, randomized study (Registration No. ChiCTR‐OCH‐14004528) aimed to compare the efficacy and effects of oxcarbazepine (OXC) with levetiracetam (LEV) as monotherapies on patient quality of life and mental health for patients with newly diagnosed focal epilepsy from China. Methods Patients with newly diagnosed focal epilepsy who had experienced 2 or more unprovoked seizures at greater than a 24‐h interval during the previous year were recruited. Participants were randomly assigned to the OXC group or LEV group. Efficacy, safety, quality of life, and mental health were evaluated over 12‐week and 24‐week periods. Results In total, we recruited 271 newly diagnosed patients from 23 centers. Forty‐four patients were excluded before treatment for reasons. The rate of seizure freedom of OXC was significantly superior to that of LEV at 12 weeks and 24 weeks (p < 0.05). The quality of life (except for the seizure worry subsection) and anxiety scale scores also showed significant differences from before to after treatment in the OXC and LEV groups. Conclusions OXC monotherapy may be more effective than LEV monotherapy in patients with newly diagnosed focal epilepsy. Both OXC and LEV could improve the quality of life and anxiety state in adult patients with focal epilepsy.

The Comparison of Levetiracetam and Piracetam Effectiveness on Breath-Holding Spells in Children: A Randomized Controlled Clinical Trial. Adv Biomed Res 2022; 10:47. [PMID: 35127574 PMCID: PMC8781912 DOI: 10.4103/abr.abr_234_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2020] [Revised: 01/12/2021] [Accepted: 02/03/2021] [Indexed: 11/04/2022] Open
Abstract
Background: We aimed to compare the effectiveness of Levetiracetam and Piracetam on the severity and frequency of spells in children with severe breath-holding spells (BHS), i.e. bening, paroxysmal, and nonepileptic events that are common in early childhood. Materials and Methods: This study is a randomized controlled clinical trial in 71 children from 6 months to 6 years of age with BHS. They were randomly assigned to the two study groups (Levetiracetam and Piracetam group). The frequency and severity of BHS and the response to treatment were recorded on monthly visits during our 3 months follow-up. Results: There was a significant decline in the average number of frequency of spells before and after 3 months of treatment in each group in this study. Levetiracetam had significant effects on the average incidence of the loss of consciousness and seizure-like movements in our study, while Piracetam had no significant effect on the loss of consciousness. Our result showed better response in the Levetiracetam group (88.9% partial or complete response after treatment) compared with the Piracetam group (77.1% partial or complete response after treatment); however, it was not significant. It seems that Levetiracetam had better effect than Piracetam in some aspects in the treatment of BHS. Conclusions: Both Piracetam and Levetiracetam are safe and had significant effects on the frequency of BHS in our study, however, levetiracetam showed superior effects on the severity of BHS.

Abstract
BACKGROUND Contemporary research indicates the role of neuroinflammation/inflammatory markers in epilepsy. In addition, comorbidities such as anxiety and poor health-related quality of life are vital concerns in clinical care of pediatric patients with epilepsy. This open-label, prospective, observational study evaluated the effect of valproate and add-on levetiracetam on serum levels of C-C motif ligand 2 (CCL2) and Interleukin-1 beta (IL-1β) in pediatric patients with epilepsy. We also studied effect of valproate and add-on levetiracetam on anxiety and health-related quality of life (HRQoL) in specified age subgroups. METHODS Children aged 1 to 12 years, diagnosed with epilepsy (generalized or focal seizures), treated with valproate (n = 40) and valproate with add-on levetiracetam (n = 40) were included. All patients were followed up for 16 weeks and assessed for changes in serum CCL2 and IL-1β levels. Spence Children Anxiety Scale short version (SCAS-S) and QOLCE-16 scales were used to measure anxiety and HRQoL, respectively, in specific age groups. RESULTS The serum CCL2 level decreased significantly (p < .001) from 327.95 ± 59.07 pg/ml to 207.02 ± 41.50 pg/ml in the valproate group and from 420.65 ± 83.72 pg/ml to 250.06 ± 46.05 pg/ml in the add-on levetiracetam group. Serum IL-1β level did not change significantly in both groups. Spence Children Anxiety Scale short version scores were decreased and QOLCE-16 scores were increased significantly (p < .001) in both valproate and add-on levetiracetam groups. CONCLUSIONS The results of our study suggest that valproate and levetiracetam led to decrease serum CCL2 levels without any change in serum IL-1β levels in children with epilepsy. Anti-inflammatory property of valproate and levetiracetam might underlie their antiepileptic effect and CCL2 could be a potential marker of drug efficacy in epilepsy. Also, valproate and levetiracetam reduced anxiety and improved quality of life in children with epilepsy in the age groups evaluated.

A Randomized Double Blind Controlled Study. Pediatr Neurol 2021; 119:15-21.

Abstract
BACKGROUND Levetiracetam is a relatively new-generation antiseizure drug approved for the treatment of focal and generalized seizures. Despite its favorable side effect profile and minimal drug-drug interactions, neuropsychiatric side effects are reported in up to 13% of children. A few case series have suggested that supplementation of pyridoxine may mitigate these side effects, but controlled trials are lacking. To address this issue, a randomized interventional study was carried out in a pediatric tertiary hospital to qualify and quantify the potential beneficial effect of pyridoxine in attenuating the neuropsychiatric side effects of levetiracetam in children. METHODS A total of 105 children with epilepsy who were taking levetiracetam (as a monotherapy or an adjunct) who showed behavioral symptoms coinciding with the start of levetiracetam, were included. Patients randomly and blindly received either a therapeutic (pyridoxine group, 46 of 105, 44%) or a homeopathic dose of pyridoxine (placebo, 59 of 105, 56%). A 30-item behavioral checklist was used to qualify and quantify the behavioral side effects at baseline and at different time points following initiation of treatment. RESULTS Both placebo and pyridoxine groups experienced a statistical reduction in behavioral scores when compared with baseline. Our study indicated that although there was a placebo effect, the improvement in neuropsychiatric symptoms was more prominent in children who received therapeutic doses of pyridoxine. CONCLUSIONS These data provide clinicians with pertinent evidence-based information that suggests that a trial of pyridoxine in patients who experience behavioral side effects due to the use of levetiracetam may avoid unnecessary change of antiseizure medications.

Abstract
OBJECTIVES Levetiracetam (LEV) is a second-generation antiepileptic drug with high efficacy and tolerability in children and adults with epilepsy. We aimed to retrospectively assess the long-term efficacy, tolerability, and safety of LEV monotherapy in children with epilepsy. METHODS All patients who received LEV monotherapy at the Ankara University Children Hospital between January 2010 and June 2020 were evaluated. This retrospective pediatric cohort study determined the efficacy and safety of LEV monotherapy in 281 outpatients with epilepsy. RESULTS There were 281 patients, 50.5% female, aged 5 months to 18 years with a mean age of 9 years. Of these, 48% of patients had idiopathic epilepsy, 40.6% had symptomatic epilepsy, and 11,4% had cryptogenic/genetic epilepsy. Primary generalized seizures occurred in 61.6% of patients, focal seizures in 19.6%, both generalized and focal seizures in 15,3%, focal to bilateral tonic-clonic seizures in 2.5%, and undefined type of seizure in 1.1%. A total of 22.8% patients had an accompanying extra neurological disease, mostly cardiological and hematological. The range of final daily dose was 10-71 mg/kg/day, with mean 29.5 mg/kg/day. Duration of therapy ranged from 7 days to 96 months, with median 12 months (IQR: 6-22). For the all cohort, a 6th month retention rate was 81%, a 12th month retention rate was 71.4%, and a 24th month retention rate was 61.8%. Eighty five percent of the patients had a seizure reduction of at least 50% and 55.9% of patients remained seizure-free for median 12 months treatment duration with LEV monotherapy. Improvement of electroencephalography (EEG) findings was found in 42% of patients on control EEGs. A total of 67 adverse events were documented in 45 (16%) patients. The most common adverse events were behavioral problems such as aggression (n:18) and irritability (n:17). The discontinuation rate due to adverse events was 2.5%, and due to inefficacy was 5.3%. CONCLUSION The present study suggests that the high retention rates, high percentage of seizure reduction, the low discontinuation rate due to adverse events and inefficacy, and the relatively benign and transient profile of adverse events make LEV preferable as monotherapy in the pediatric population.

Abstract
Introduction: Management of individuals with Dravet Syndrome has evolved significantly over the past 10 years. Progress has been made in understanding the pathophysiology, the long-term outcome and possible consequences of inappropriate therapies, new drugs have been approved by the regulatory authorities and patients and families expressed their needs beyond seizures' control.Areas covered: The authors aimed at providing an overview of the main antiseizure medications used in Dravet syndrome with a particular focus on safety considerations. As the highly active phase of seizures takes place before the age of 5 years, the characteristics of antiseizure medications in infancy and childhood have also been considered due to their impact on antiseizure medication safety.Expert opinion: Recent treatments, evaluated via randomized clinical trials, are promising in terms of efficacy and safety in individuals with DS. However, the balance between expected benefits and risks taken must be accurately assessed on an individual basis. There is a lack of data to understand the needs of patients and families, a major point particularly in this population, where the evaluation of efficacy and safety beyond seizures is difficult due to cognitive delay and behavioral disorders and where this evaluation is coming almost exclusively from caregivers.

Abstract
This study examines an 11-year-old boy with a known history of a large previously asymptomatic arachnoid cyst (AC) presenting with acute onset of right facial droop, hemiplegia, and expressive aphasia. Shortly after arrival to the emergency department, the patient exhibited complete resolution of right-sided hemiplegia but developed headache and had persistent word-finding difficulties. Prior to symptom onset while in class at school, there was an absence of reported jerking movements, headache, photophobia, fever, or trauma. At the time of neurology consultation, the physical exam showed mildly delayed cognitive processing but was otherwise unremarkable. The patient underwent MRI scanning of the brain, which revealed left convexity subdural hematohygroma and perirolandic cortex edema resulting from ruptured left frontoparietal AC. He was evaluated by neurosurgery and managed expectantly. He recovered uneventfully and was discharged two days after presentation remaining asymptomatic on subsequent outpatient visits. The family express concerns regarding increased anxiety and mild memory loss since hospitalization.

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. [PMID: 33181889 DOI: 10.1016/j.yebeh.2020.107472] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2020] [Revised: 09/04/2020] [Accepted: 09/06/2020] [Indexed: 11/22/2022]
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.

Safety of azithromycin in pediatrics: a systematic review and meta-analysis. Eur J Clin Pharmacol 2020; 76:1709-1721. [PMID: 32681202 PMCID: PMC7661415 DOI: 10.1007/s00228-020-02956-3] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Accepted: 07/06/2020] [Indexed: 02/07/2023]
Abstract
Purpose To evaluate the toxicity of azithromycin in neonates, infants, and children. Methods A systematic review was performed for relevant studies using Medline (Ovid), PubMed, Cochrane Central Register of Controlled Trials, EMBASE, CINAHL, and International Pharmaceutical Abstracts. We calculated the pooled incidence of adverse drug reactions (ADRs) associated with azithromycin based on prospective studies (RCTs and prospective cohort studies) and analyzed the risk difference (RD) of ADRs between azithromycin and placebo or other antibiotics using meta-analysis of RCTs. Results We included 133 studies with 4243 ADRs reported in 197,675 neonates, infants, and children who received azithromycin. The safety of azithromycin as MDA in pediatrics was poorly monitored. The main ADRs were diarrhea and vomiting. In prospective non-MDA studies, the most common toxicity was gastrointestinal ADRs (938/1967; 47.7%). The most serious toxicities were cardiac (prolonged QT or irregular heart beat) and idiopathic hypertrophic pyloric stenosis (IHPS). Compared with placebo, azithromycin did not show increased risk ADRs based on RCTs (risk difference − 0.17 to 0.07). The incidence of QT prolonged was higher in the medium-dosage group (10–30 mg/kg/day) than that of low-dosage group (≤ 10 mg/kg/day) (82.0% vs 1.2%). Conclusion The safety of azithromycin as MDA needs further evaluation. The most common ADRs are diarrhea and vomiting. The risk of the most serious uncommon ADRs (cardiac-prolonged QT and IHPS) is unknown.

Abstract
In veterinary medicine levetiracetam (LEV) is a well-tolerated antiepileptic drug (AED) with only mild to moderate side effects. Behavioral changes are rarely reported in animals. In contrast, in human medicine the impact of LEV on behavior has frequently been described. Since in the Clinic for Small Animals at the University of Veterinary Medicine Hannover single canine patients were observed with behavioral abnormalities after LEV treatment, it was hypothesized that levetiracetam induces behavioral changes or causes an intensifying of pre-existing behavioral abnormalities in dogs with epileptic seizures. This monocentric retrospective study evaluated the incidence of behavioral changes in epileptic dogs treated with the antiepileptic drug LEV based on information obtained in a questionnaire completed by dog owners. Eighty-four client-owned dogs with recurrent seizures receiving LEV as monotherapy, add on treatment or pulse therapy met inclusion criteria. Approximately half of the dogs in the study population were reported to have preexisting behavioral changes before treatment with LEV, and some of these dogs were reported to experience a worsening of behavioral changes (14/44) or the emergence of new behaviors after initiation of LEV therapy (4/44). One quarter of the dogs without pre-existing behavioral abnormalities developed behavioral changes associated with the administration of LEV (10/40). Based on these results, the authors conclude that behavioral changes can occur in dogs being administered LEV, and this should be taken into consideration when discussing treatment options with owners.

Safety and tolerability of adjunctive brivaracetam in children with focal seizures: Interim analysis of pooled data from two open-label trials. Eur J Paediatr Neurol 2020; 25:68-76. [PMID: 31810577 DOI: 10.1016/j.ejpn.2019.11.007] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2019] [Revised: 06/27/2019] [Accepted: 11/17/2019] [Indexed: 12/28/2022]
Abstract
OBJECTIVE To evaluate long-term safety and tolerability of adjunctive brivaracetam (BRV) in children with epilepsy. METHODS This was an interim analysis (cut-off March 15, 2017) of pooled data from two open-label, single-arm, multicentre trials. N01263 (NCT00422422) was a 3-week trial of BRV 0.8-4 mg/kg/day in patients (1 month-<16 years) with epilepsy. Patients who completed this trial could continue into a long-term follow-up trial (N01266, NCT01364597) which also directly enrolled patients (4-<17 years) with focal seizures. After dose-escalation, patients received BRV 1-5 mg/kg/day (maximum 200 mg/day) during long-term evaluation. Data are reported for patients aged 4 to <16 years with focal seizures. RESULTS The safety set comprised 149 patients: 34 from the initial trial (26 entered long-term trial) and 115 directly enrolled into the long-term trial. At the cut-off, 90 patients were receiving BRV (total exposure: 299.4 patient-years). Treatment-emergent adverse events (TEAEs) were reported by 140/149 (94.0%) patients, most commonly (≥20%) nasopharyngitis (24.8%), pharyngitis (22.1%), convulsion (21.5%), and pyrexia (20.1%). TEAEs considered drug-related by the investigator were reported by 56/149 (37.6%) patients, most commonly somnolence (6.0%). Two patients died; neither death was considered related to BRV. Mean changes from baseline in child behaviour rating scales were small; most patients remained in their baseline category. CONCLUSION In this pooled analysis of two open-label trials including long-term data, adjunctive BRV was generally well tolerated in children aged 4 to <16 years with focal seizures. These findings supported approval of BRV as a new therapy option for children aged ≥4 years with focal seizures.

Abstract
In contrast to epilepsy in adolescents and adults, neonatal seizures and early onset epilepsy poses unique challenges with significant repercussion for treatment choices. Most importantly, high seizure burden and epileptic encephalopathy are associated with developmental, behavioural and cognitive problems. The causes are multifactorial and include etiology, seizure burden, epileptic encephalopathy, but also antiseizure medication. In contrast to adults and older children only very few drugs have been licenced for infants and neonates, and after a long delay. Very recently, extrapolation of adult data has become possible as a path to speed up drug development for younger children but this is not necessarily possible for infants and neonates. With the advances in understanding the molecular basis of many epilepsies, targeted therapies become available, for example for KCNQ2 mutation related epilepsies, Dravet syndrome or tuberous sclerosis complex. Drug trials in neonates are particularly challenging because of their inconspicuous clinical presentation, the need for continuous EEG monitoring, high co-morbidity, and poor response to antiepileptic drugs. There is an urgent need for development of new drugs, evaluation of safety and efficacy of current antiseizure drugs, as well as for national policies and guidelines for the management of seizures and epilepsy in neonates and infants. This article is part of the special issue entitled 'New Epilepsy Therapies for the 21st Century - From Antiseizure Drugs to Prevention, Modification and Cure of Epilepsy'.

Abstract
PURPOSE OF REVIEW Children surviving the pediatric intensive care unit (PICU) with neurologic illness or injury have long-term morbidities in physical, cognitive, emotional, and social functioning termed postintensive care syndrome (PICS). In this article, we review acute and longitudinal management strategies available to combat PICS in children with acquired brain injury. RECENT FINDINGS Few intervention studies in this vulnerable population target PICS morbidities. Small studies show promise for both inpatient- and outpatient-initiated therapies, mainly focusing on a single domain of PICS and evaluating heterogeneous populations. While evaluating the effects of interventions on longitudinal PICS outcomes is in its infancy, longitudinal clinical programs targeting PICS are increasing. A multidisciplinary team with inpatient and outpatient presence is necessary to deliver the holistic integrated care required to address all domains of PICS in patients and families. While PICS is increasingly recognized as a chronic problem in PICU survivors with acquired brain injury, few interventions have targeted PICS morbidities. Research is needed to improve physical, cognitive, emotional, and social outcomes in survivors and their families.

Cognitive profile in BECTS treated with levetiracetam: A 2-year follow-up. Epilepsy Behav 2019; 97:187-191. [PMID: 31252277 DOI: 10.1016/j.yebeh.2019.05.046] [Citation(s) in RCA: 26] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2019] [Revised: 05/24/2019] [Accepted: 05/31/2019] [Indexed: 11/22/2022]
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
INTRODUCTION Epilepsy causes serious suffering in children and is associated with high morbidity and increased mortality. It impairs children's quality of life and places a heavy burden on healthcare resources. Levetiracetam has been used to prevent and treat paediatric epilepsy for years. To date, a number of systematic reviews have been performed to assess the efficacy and safety of levetiracetam in a variety of clinical settings. Conflicting outcomes have been reported for the same clinical issues. Our objective is to provide a comprehensive overview of the literature for clinicians and policymakers via an umbrella review that assesses the efficacy and safety of levetiracetam in children with epilepsy. METHODS AND ANALYSIS We will follow the Joanna Briggs Institute's guidelines for umbrella reviews and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. The following seven databases will be searched from 1990 to February 2019: PubMed, Embase, Cochrane Database of Systematic Reviews, JBISRIR, EPPI, Epistemonikos and PROSPERO. We will provide evidence from existing systematic reviews and meta-analyses of randomised controlled trials regarding the use of levetiracetam in children with epilepsy. The intervention of interest is levetiracetam monotherapy and add-on therapies for prevention or treatment purposes. Studies will be individually selected and assessed by two reviewers. The primary outcomes of interest are epilepsy control, the efficacy of prophylaxis for provoked seizures and the mortality rate of children with epilepsy who received levetiracetam treatment. The secondary outcomes are adverse events and withdrawal rates due to adverse effects. The methodological quality of all reviews will be individually assessed by two reviewers using the 'A Measurement Tool to Assess Systematic Reviews' instrument. The Grading of Recommendations Assessment, Development and Evaluation assessment will be applied to evaluate the quality of evidence for each outcome of interest. A narrative description of an analysis of the systematic reviews will be tabulated to address objective and specific questions. Information from each review will be detailed in a table including the population, number of studies, total number of participants, year range of the trials, study designs of the primary trials, countries and settings of the trials, heterogeneity of results and assessment tools. Recommendations regarding each outcome of levetiracetam will be categorised based on a protocol. ETHICS AND DISSEMINATION This umbrella review will inform clinical and policy decisions regarding the efficacy and safety of levetiracetam for preventing and treating paediatric epilepsy. The results will be disseminated through a peer-reviewed publication and conference presentations. Ethical approval is not required for this study.

Abstract
OBJECTIVE The objective of this study was to investigate the efficacy and safety profile of levetiracetam as add-on therapy in patients with refractory epilepsy. METHODS Web of Science, MEDLINE (Ovid and PubMed), Cochrane Library, EMBASE, and Google Scholar were systematically searched to identify potential eligible randomized controlled trials by two reviewers independently. Pooled estimates of risk ratios (RRs) for 50%, 75%, and 100% reduction from baseline were calculated using the fixed-effect model or random-effect model. Quality of included studies was assessed with the Cochrane Collaboration's Risk of Bias tool. Serious adverse events and withdrawals induced by interventions and the most common side effects were analyzed. RESULTS Seventeen trials with a total of 3,205 participants were included in this meta-analysis, including 14 trials for adulthood and three trials for children. Pooled estimates suggested that levetiracetam was an effective anti-epileptic drug at 1,000-3,000 mg/day (RR =2.00 for 1,000 mg/day, RR =2.68 for 2,000 mg/day, RR =2.18 for 3,000 mg/day) for adults and 60 mg/kg/day (RR =2.00) for children compared to placebo in terms of 50% reduction from baseline. Likewise, as for seizure freedom rate, levetiracetam had an advantage over placebo at 1,000-3,000 mg/day (RR =5.84 for 1,000 mg/day, RR =4.55 for 2,000 mg/day, RR =4.57 for 3,000 mg/day, respectively) for adults and 60 mg/kg/day (RR =4.52) for children. Regarding safety profile, patients treated with levetiracetam had significantly higher occurrence than placebo for somnolence, asthenia, dizziness, infection, nasopharyngitis, anxiety, and irritability; however, most studies reported that these adverse events were mild and transient. CONCLUSION Levetiracetam is an effective anti-epileptic drug for both adults and children with generalized or partial-onset refractory seizures at 1,000-3,000 or 60 mg/kg/day, with a favorable adverse event profile.

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. REGISTERED NUMBER PROSPERO (No CRD 42017069367).

Abstract
INTRODUCTION Treatment of pediatric epilepsy requires a careful evaluation of the safety and tolerability profile of antiepileptic drugs (AEDs) to avoid or minimize as much as possible adverse events (AEs) on various organs, hematological parameters, and growth, pubertal, motor, cognitive and behavioral development. AREAS COVERED Treatment-emergent AEs (TEAEs) reported in the literature 2000-2018 regarding second- and third-generation AEDs used in the pediatric age, with exclusion of the neonatal period that exhibits specific peculiarities, have been described on the basis of their frequency, severity/tolerability, and particular association with a given AED. EXPERT OPINION Somnolence/sedation and behavioral changes, like irritability and nervousness, are among the most commonly observed TEAEs associated with almost all AEDs. Lamotrigine, Gabapentin, Oxcarbazepine, and Levetiracetam appear to be the best-tolerated AEDs with a ≤2% withdrawal rate, while Tiagabine and Everolimus are discontinued in up to >20% of the patients because of intolerable TEAEs. For some AEDs, literature data are scanty to draw a high-level evidence on their safety and tolerability profile. The reasons are: insufficient population size, short duration of treatments, or lack of controlled trials. A future goal is that of identifying clearer, easier, and more homogeneous methodological strategies to facilitate AED testing in pediatric populations.

Abstract
AIM This paper presents the prevalence of antiepileptic polytherapy at a single tertiary institution and systematically reviews the evidence base for its efficacy and neurobehavioural safety in children. METHOD Prevalence of antiepileptic polypharmacy was determined from pharmacy dispensing records at a paediatric tertiary hospital and neurobehavioural comorbidities quantified through casenote review; comparison is made with studies evaluating the neurobehavioural safety of antiepileptic polytherapy, identified via systematic literature review. RESULTS Amongst 262 patients at the hospital, 117 (44.7%) were prescribed polytherapy; with patients having an intellectual disability statistically more likely to be prescribed polytherapy than those without (70.5% vs 40.6%; p < 0.0001). Systematic review identified no trials addressing the efficacy or neurobehavioural outcomes of polytherapy as a primary outcome. Several observational studies identified associations between polytherapy and neurobehavioural adverse outcomes such as anxiety and behavioural disturbance. Observational studies also suggest that a reduction in polytherapy load is generally not associated with worsening seizure control. CONCLUSION Whilst antiepileptic polytherapy is common practice within paediatric epilepsy cohorts attending tertiary care institutions, evidence is lacking to support its efficacy. There are significant practical difficulties to undertaking randomised controlled trials within this population. Nonetheless, clinicians must consider that adverse neurobehavioural consequences of polytherapy might outweigh benefits to seizure control.

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
INTRODUCTION Ceftriaxone is widely used in children in the treatment of sepsis. However, concerns have been raised about the safety of ceftriaxone, especially in young children. The aim of this review is to systematically evaluate the safety of ceftriaxone in children of all age groups. METHODS AND ANALYSIS MEDLINE, PubMed, Cochrane Central Register of Controlled Trials, EMBASE, CINAHL, International Pharmaceutical Abstracts and adverse drug reaction (ADR) monitoring systems will be systematically searched for randomised controlled trials (RCTs), cohort studies, case-control studies, cross-sectional studies, case series and case reports evaluating the safety of ceftriaxone in children. The Cochrane risk of bias tool, Newcastle-Ottawa and quality assessment tools developed by the National Institutes of Health will be used for quality assessment. Meta-analysis of the incidence of ADRs from RCTs and prospective studies will be done. Subgroup analyses will be performed for age and dosage regimen. ETHICS AND DISSEMINATION Formal ethical approval is not required as no primary data are collected. This systematic review will be disseminated through a peer-reviewed publication and at conference meetings. PROSPERO REGISTRATION NUMBER CRD42017055428.

Abstract
BACKGROUND In pediatric epilepsy, neurodevelopmental comorbidities could be sometimes even more disabling than seizures themselves, therefore it is crucial for the clinicians to understand how to benefit these children, and to choose the proper antiepileptic drug for the treatment of epilepsy associated to a specific neurodevelopmental disorder. Aim of this paper is to discuss the potential impact on cognition and behavior of new and newest AEDs and to guide the choice of the clinicians for a targeted use in epilepsy associated with specific neurodevelopmental disorders. METHODS Information in this review is mainly based on peer-reviewed medical publications from 2002 until October 2016 (PubMed). We choose to include in our review only the AEDs of second and third generation approved for pediatric population. RESULTS Vigabatrin, lamotrigine, topiramate, levetiracetam, oxcarbazepine, zonisamide, rufinamide, lacosamide, eslicarbazepine, and perampanel have been included in this review. The most tolerated AEDs from a cognitive and behavioral point of view are lamotrigine and rufinamide, thus representing optimal drugs for children with cognitive and/or attention problems. DISCUSSION Most of the new AEDs are initially licensed for adult patients. Data on children are usually very limited, both in terms of efficacy and safety, and the use standardized cognitive and behavioral outcome measures are very limited in pediatric clinical trials. CONCLUSION Several factors including polytherapy, administration of AEDs with the same mechanism of action and the dose and titration of the drug, should be considered as important in the development of cognitive and behavioral side effects.

Abstract
BACKGROUND Epilepsy is a common chronic disease of children that can be treated with anti-epileptic drugs (AEDs). AEDs, however, have significant side effects. Newer AEDs are thought to have fewer side effects. There have, however, been few comparative studies of AED toxicity. The aim is to compare the safety profile of the most frequently used AEDs by performing a multicentre prospective cohort study. This protocol describes the planned study. DESIGN A multicentre prospective cohort study of children on AED treatment in hospitals across the UK. Ethical approval will be obtained. SAMPLE SIZE Three thousand children on treatment for epilepsy will be recruited from paediatric clinics. It is expected that this sample size will have the potential to compare toxicity between the most frequently used AEDs. DURATION OF STUDY 24 months. OUTCOME MEASURE Adverse drug reactions (ADRs) to AEDs. These will be identified by the use of a validated questionnaire, the Paediatric Epilepsy Side Effect Questionnaire. They will be evaluated using the Naranjo algorithm. Preventability will be assessed using the Schumock and Thornton scale. DISCUSSION Toxicity of individual AEDs when given as monotherapy and polytherapy will be determined. Additionally, discontinuation rates due to ADRs will be determined. The data will assist clinicians in choosing AEDs with the least toxicity.
