Rhabdomyolysis can occur because of multiple causes and account for 7% of all cases of acute kidney injury annually in the United States. Identification of specific cause can be difficult in many cases where multiple factors could potentially cause rhabdomyolysis. We present a case of 16-year-old male who had seizures and was given levetiracetam that resulted in rhabdomyolysis. This side effect has been rarely reported previously and like in our case diagnosis may be delayed.

PURPOSE: Status epilepticus (SE) requires not only urgent symptomatic treatment with antiepileptic drugs but also rapid identification and treatment of its cause. This narrative review summarizes the most important advances in classification and treatment of SE. METHOD: Data sources included MEDLINE, EMBASE, ClinicalTrials.gov, and back tracking of references in pertinent studies, reviews, and books. RESULTS: SE is now defined as "a condition resulting either from the failure of the mechanisms responsible for seizure termination or from the initiation of mechanisms, which lead to abnormally, prolonged seizures (after time point t1)...

BACKGROUND: Patients with severe motor and intellectual disabilities (SMID) are those who have both severe intellectual disabilities and severe physical disabilities. Intractable epilepsy is often associated with SMID. The purpose of this study was to elucidate the relationship between epilepsy associated with SMID and oxidative stress, and to clarify the safety and efficacy of the newer antiepileptic drugs (newer AEDs), lamotrigine and levetiracetam. METHODS: This study was conducted in 27 SMID patients with epilepsy who were treated with the newer AEDs...

BACKGROUND: Recent clinical evidence supports a targeted therapeutic approach for genetic epileptic encephalopathies based on the molecular dysfunction. PATIENT DESCRIPTION: A 2-day-old male infant presented with epileptic encephalopathy characterized by burst-suppression EEG background and tonic-clonic migrating partial seizures. The condition was refractory to phenobarbital, pyridoxine, pyridoxal phosphate and levetiracetam, but a dramatic response to an intravenous loading dose of phenytoin was documented by video-EEG monitoring...

About 30% of the patients with epilepsy do not respond to clinically established anticonvulsants, despite having effective concentrations of the antiepileptic drug in plasma. Therefore, new preclinical models of epilepsy are needed to identify more efficacious treatments. We describe here a new drug-resistant seizure model in mice to be used at the early stages of pre-clinical trials. This model consists in inducing daily generalized seizures for 23 consecutive days by administration of 3-mercaptopropionic acid (MP)...

The objective of this study was to determine the efficacy and safety of levetiracetam in treatment of neonatal seizures due to hypoxic ischemic encephalopathy. Seizures often persist in neonates with hypoxic ischemic encephalopathy despite phenobarbital. A retrospective single-center study was conducted in neonates ≥36 weeks gestation with hypoxic ischemic encephalopathy. A total of 127 neonates were identified born 2008-2015. Clinical seizures occurred in 83 infants. Fifty-one neonates (61%) had cessation of seizures with only phenobarbital...

OBJECTIVE: Prophylactic medications can be a source of preventable harm, potentially affecting large numbers of patients. Few data exist about how clinicians change prescribing practices in response to new data and revisions to guidelines about preventable harm from a prophylactic medication. We sought to determine the changes in prescribing practice of seizure medications for patients with intracerebral hemorrhage (ICH) across a metropolitan area before and after new outcomes data and revised prescribing guidelines were published...

SV2A is a glycoprotein present in the membranes of most synaptic vesicles. Although it has been highly conserved throughout evolution, its physiological role remains largely unknown. Nevertheless, Levetiracetam, a very effective anti-epileptic drug, has been recently demonstrated to bind to SV2A. At present, our understanding of the normal function of SV2A and its possible involvement in diseases like epilepsy is limited. With this study, we sought to develop a relevant model enabling analysis of SV2A's role in the occurrence or progression of epilepsy...

BACKGROUND: Perioperative seizure prophylaxis with antiepileptic drugs (AED) has been advocated in patients undergoing supratentorial craniotomy. The practice remains controversial. The reasoning presupposes that the possibility of an adverse drug reaction from the AED is lower than the probability of harm from a seizure. Even short periods of hypotension during the operation can lead to acute kidney and myocardial injury. We retrospectively evaluated cardiovascular effects and tolerability of Levetiracetam (LEV) alone, LEV and Lacosamid (LCM) as compared to Phenytoin (PHT)...

Gap junctions (GJs) in astrocytes and glioma cells are important channels for cell-to-cell communication that contribute to homo- and heterocellular coupling. According to recent studies, heterocellular gap-junctional communication (H-GJC) between glioma cells and their surrounding environment enhances glioma progression. Therefore, we developed a new in vitro model to examine H-GJC between glioma cells, astrocytes and microglia. Consequently, F98 rat glioma cells were double-labeled with GJ-impermeable (CM-DiI) and GJ-permeable dye (calcein AM) and were seeded on unlabeled astrocyte-microglia co-cultures...

Epilepsy is the most common neurological disorder affecting approximately 50 million people worldwide. In India, overall prevalence of epilepsy is reported to be 5.59/1000 population. Antiepileptic drugs (AEDs) constitute the main-stay of treatment with a large number of AEDs available in the market. High incidence of adverse effects is a major limitation with AEDs. One of the major concerns is significant metabolic effects on the bone. However, little attention has been paid to this issue because most of the bone effects remain subclinical for a long time and may take years to manifest clinically...

Idiosyncratic hepatotoxicity is one of the most common reasons for an approved drug being restricted. This article focuses on hepatotoxicity of selected and recently introduced agents, such as, tyrosine kinase inhibitors, monoclonal antibodies, novel oral anticoagulants, newer antiplatelets, antibiotics, anti-diabetics, anti-epileptics, anti-depressants, anti-psychotics and anti-retrovirals. Overall, the incidence of clinically relevant hepatotoxicity from newer agents seems to be lower than that of the older agents...

BACKGROUND & OBJECTIVES: Though newer antiepileptic drugs are considered safer than conventional antiepileptics, the effects of lamotrigine, levetiracetam and topiramate on neurobehavioural functions are yet to be established. This study evaluated neurobehavioural parameters and oxidative stress markers in brain tissue of rats treated with lamotrigine, levetiracetam and topiramate compared to sodium valproate . METHODS: Five groups of male Wistar rats were treated respectively with normal saline (control), sodium valproate (370 mg/kg), lamotrigine (50 mg/kg), levetiracetam (310 mg/kg) and topiramate (100 mg/kg) for 45 days...

OBJECTIVE: Neonatal seizures are a common problem in the neonatal intensive care unit and are frequently treated with antiepileptic drugs. Limited data exist on current or changing antiepileptic drug use for seizures in the neonatal intensive care unit.We sought to describe trends of antiepileptic drug exposure in a large volume of US neonatal intensive care unit from 2005 to 2014 and we hypothesized increasing levetiracetam exposure over the 10-year study period. STUDY DESIGN: Retrospective cohort study of infants from the Pediatrix Medical Group Clinical Data Warehouse, a large, multicenter, deidentified data set...

Levetiracetam (LEV) is an antiepileptic drug that is clinically effective in generalized and partial epilepsy syndromes. The use of this drug has been increasing in clinical practice and intra- or -interindividual variability has been exhibited for special population. For this reason, bioanalytical methods are required for drug monitoring in biological matrices. So this work presents a dispersive liquid-liquid microextraction method followed by gas chromatography-mass spectrometry (DLLME-GC-MS) for LEV quantification in human plasma...

BACKGROUND: There is evidence that certain antiepileptic drugs (AEDs) are teratogenic and are associated with an increased risk of congenital malformation. The majority of women with epilepsy continue taking AEDs throughout pregnancy; therefore it is important that comprehensive information on the potential risks associated with AED treatment is available. OBJECTIVES: To assess the effects of prenatal exposure to AEDs on the prevalence of congenital malformations in the child...

OBJECTIVE: Antiepileptic drug (AED) treatment failures may occur because there is insufficient drug in the brain or because of a lack of relevant therapeutic response. Until now it has not been possible to measure these factors. It has been recently shown that the combination of transcranial magnetic stimulation and electroencephalography (TMS-EEG) can measure the effects of drugs in healthy volunteers. TMS-evoked EEG potentials (TEPs) comprise a series of positive and negative deflections that can be specifically modulated by drugs with a well-known mode of action targeting inhibitory neurotransmission...
