Abstract
Appropriate treatment of neonatal seizures with an effective therapy is important in reducing long-term neurologic disabilities. Sixty-seven neonates, who received intravenous (IV) levetiracetam (LEV) as first-line therapy for treating seizures between 2013 and 2017 were evaluated retrospectively to investigate the efficacy of LEV and its neurodevelopmental outcome at 12 months of age. Of the 67 neonates (44 preterm and 23 term babies) evaluated for seizures, 55 (82%) had a defined etiology. EEG confirmation was obtained in 36 (57.1%) of the neonates with clinical seizures. On the 7th day of the treatment (mean seizure control time 7.4 ± 15.1 days), LEV was effective as monotherapy in 43 (64%), whereas add-on therapy was required in 24 (36%) neonates. At the 1-year follow-up, 76% of infants achieved drug-free state, nine (18%) infants remained on LEV monotherapy and three (6%) needed add-on therapy. Neurodevelopmental outcome of the infants was assessed with Ankara Development Screening Inventory and results suggested favorable neurodevelopmental outcome in 69.7% of the infants with at the end of the 1-year follow-up with LEV monotherapy. In conclusion, this retrospective cross-sectional study demonstrated that IV LEV is an effective first-line therapy for treating neonatal clinical seizures and LEV monotherapy effect was sustained during the first year follow-up.

Abstract
Aim The existing treatment options for neonatal seizures have expanded over the last few decades, but no consensus has been reached regarding the optimal therapeutic protocols. We systematically reviewed the available literature examining neonatal seizure treatments to clarify which drugs are the most effective for the treatment of specific neurologic disorders in newborns. Method We reviewed all available, published, literature, identified using PubMed (published between August 1949 and November 2020), that focused on the pharmacological treatment of electroencephalogram (EEG)-confirmed neonatal seizures. Results Our search identified 427 articles, of which 67 were included in this review. Current knowledge allowed us to highlight the good clinical and electrographic responses of genetic early-onset epilepsies to sodium channel blockers and the overall good response to levetiracetam, whose administration has also been demonstrated to be safe in both full-term and preterm newborns. Interpretation Our work contributes by confirming the limited availability of evidence that can be used to guide the use of anticonvulsants to treat newborns in clinical practice and examining the efficacy and potentially harmful side effects of currently available drugs when used to treat the developing newborn brain; therefore, our work might also serve as a clinical reference for future studies.

Abstract
Context: Seizures are the most frequent neurological disturbance in the neonatal period, and there are no evidence-based guidelines for the treatment of neonatal seizures. Here we report a study on the use of levetiracetam as second-line therapy in the treatment of seizures in term and preterm neonates. Aim: The aim of this study was to assess the efficacy and safety of levetiracetam for seizures of term and preterm neonates. Settings and Design: We retrospectively analyzed data of the patients who had seizures and who were treated with levetiracetam as an add-on therapy to phenobarbital during the neonatal period. Statistical Analysis: The Statistical Package for the Social Sciences (SPSS) software, version 15.0 (SPSS, Chicago, Illinois), was used for statistical analysis. Continuous variables were expressed as mean values and standard deviations. Results: Thirty-six patients (8 term and 28 preterm) received levetiracetam. Mean dose of levetiracetam was 31.67 ± 14.83mg/kg/day. Twenty-five of the patients (69.4%) were seizure free with levetiracetam treatment. Electroencephalography recordings improved in 28 (77.8%) of the patients after levetiracetam. No severe adverse effects were observed. Conclusion: Our data suggest that levetiracetam may be a safe and effective treatment for neonatal seizures, which are unresponsive to phenobarbital.

Abstract
INTRODUCTION Therapeutic schedules for treating neonatal seizures remain elusive. First-line treatment with phenobarbital is widely supported but without strong scientific evidence. Levetiracetam (LEV) is an emerging and promising antiepileptic drug (AED). The aim of this phase II trial is to determine the benefits of LEV by applying a strict methodology and to estimate the optimal dose of LEV as a first-line AED to treat seizures in newborns suffering from hypoxic-ischaemic encephalopathy. METHODS AND ANALYSIS LEVNEONAT-1 is an open and sequential LEV dose-finding study. The optimal dose is that which is estimated to be associated with a toxicity not exceeding 10% and an efficacy higher than 60%. Efficacy is defined by a seizure burden reduction of 80% after the loading dose. Four increasing dose regimens will be assessed including one loading dose of 30, 40, 50 or 60 mg/kg followed by eight maintenance doses (ie, a quarter of the loading dose) injected every 8 hours. A two-patient cohort will be necessary at each dose level to consider an upper dose level assignment. The maximal sample size expected is 50 participants with a minimum of 24 patients or fewer in the case of a high rate of toxicity. Patients will be recruited in five neonatal intensive care units beginning in October 2017 and continuing for 2 years. In parallel, the LEV pharmacokinetics will be measured five times (ie, 30 min; 4 and 7 hours after the loading dose; 1-3 hours and 12-18 hours after the last maintenance dose). ETHICS AND DISSEMINATION Ethics approval has been obtained from the regional ethical committee (2016-R25) and the French Drug Safety Agency (160652A-31). The results will be published in a peer-reviewed journal. The results will also be presented at medical meetings. TRIAL REGISTRATION NUMBER NCT02229123; Pre-results.

Abstract
Nowadays, no general consensus was achieved regarding neonatal status epilepticus and its definition. Indeed, different criteria (mainly based on seizure duration) were used. Whereas a recent proposal has been developed to define status epilepticus in older ages, it seems that the peculiar characteristics of neonatal seizures and of the immature brain make difficult to find a tailored definition for this period of life. Achieving a consensus on this entity would mean to make the first step toward a targeted therapeutic strategy of intervention.
