OBJECTIVE: To compare the efficacy and safety of lacosamide (LCM) and sodium valproate (SVA) in lorazepam (LOR)-resistant status epilepticus (SE). METHODS: Patients with LOR-resistant SE were randomized to intravenous LCM 400 mg at a rate of 60 mg/kg/min or SVA 30 mg/kg at a rate of 100 mg/min. The SE severity score (STESS), duration of SE and its etiology, and magnetic resonance imaging (MRI) findings were noted. Primary outcome was seizure cessation for 1 h, and secondary outcomes were 24 h seizure remission, in hospital death and severe adverse events (SAEs)...

PURPOSE: Valproate is one of the most commonly used anticonvulsive drugs. Despite its significant benefits, the teratogenicity of valproate is a relevant problem in the treatment of women of childbearing age. In addition to major congenital malformations, such as neural tube defects, reduced intelligence and attention after intrauterine valproate exposure are reported. Until now the mechanisms of teratogenicity of VPA are poorly understood and concepts how to reduce valproate teratogenicity are lacking...

Nitric oxide (NO), an important intracellular signaling molecule is involved in modulation of neuronal transmission. The NO level increases during epileptic activity in animal models of epilepsy. However, its role in epileptic activity remains controversial. Spermine is an endogenous polyamine; possesses anti-oxidant property and has ability to modulate ion channels and NO synthase activity. Therefore, the present study was designed to investigate the role of NO pathway in the neuroprotective effect of spermine, in Pentylenetetrazol (PTZ) induced kindling epilepsy in mice...

Stevens-Johnson syndrome is one of the few dermatological emergencies in clinical practice. The syndrome is often secondary to the usage of drugs, of which allopurinol, penicillins, sulfa drugs, ibuprofen, sodium valproate, phenytoin, lamotrigine and carbamazepine are commonly implicated. Agranulocytosis is the existence of a clinically significant reduction in neutrophil count. This condition is a serious threat to the patient, as he/she is at a greater risk of contracting bacterial or fungal infections, which may prove to be fatal...

Endoplasmic reticulum (ER) stress-induced apoptosis plays an important role in a range of neurological disorders, such as neurodegenerative diseases, spinal cord injury, and diabetic neuropathy. Valproate (VPA), a typical antiepileptic drug, is commonly used in the treatment of bipolar disorder and epilepsy. Recently, VPA has been reported to exert neurotrophic effects and promote neurite outgrowth, but its molecular mechanism is still unclear. In the present study, we investigated whether VPA inhibited ER stress and promoted neuroprotection and neuronal restoration in SH-SY5Y cells and in primary rat cortical neurons, respectively, upon exposure to thapsigargin (TG)...

BACKGROUND: This is an updated version of the original Cochrane review originally published in 2003, Issue 3, and updated in 2005, Issue 4.Absence seizures are brief epileptic seizures which present in childhood and adolescence. Depending on clinical features and electroencephalogram (EEG) findings they are divided into typical, atypical absences, and absences with special features. Typical absences are characterised by sudden loss of awareness and an EEG typically shows generalised spike wave discharges at three cycles per second...

Background and Aims: Drug-induced steatosis is a major reason for drug failure in clinical trials and post-marketing withdrawal; and therefore, predictive biomarkers are essential. These could be particularly relevant in non-alcoholic fatty liver disease (NAFLD), where most patients show features of the metabolic syndrome and are prescribed with combined chronic therapies, which can contribute to fatty liver. However, specific biomarkers to assess the contribution of drugs to NAFLD are lacking. We aimed to find microRNAs (miRNAs) responsive to steatotic drugs and to investigate if they could become circulating biomarkers for drug-induced steatosis...

The regulatory paradigm in cardiac hypertrophy involves alterations in gene expression that is mediated by chromatin remodeling. Various data suggest that class I and class II histone deacetylases (HDACs) play opposing roles in the regulation of hypertrophic pathways. To address this, we tested the effect of magnesium valproate (MgV), an HDAC inhibitor with 5 times more potency on Class I HDAC. Cardiac hypertrophy was induced by Partial abdominal aortic constriction in wistar rats, and at end of 6 weeks, we evaluated hypertrophic, hemodynamic and oxidative stress parameters, and mitochondrial DNA concentration...

Studies have suggested the involvement of inflammatory processes in the physiopathology of bipolar disorder. Preclinical evidences have shown that histone deacetylase inhibitors may act as mood-stabilizing agents and protect the brain in models of mania and depression. The aim of the present study was to evaluate the effects of sodium butyrate (SB) and valproate (VPA) on behavioral changes, histone deacetylase activity, and the levels of cytokines in an animal model of mania induced by dextroamphetamine (d-AMPH)...

BACKGROUND: Valproate acid (VPA), a commonly used antiepileptic medicine, is found to be linked to developing dysmetabolic risk. However, the proposed mechanism remains completely unknown. METHODS: In this study, we collected data from patients with epilepsy and further investigated the preclinical study in mice. RESULTS: As results, the clinical data showed that VPA-used patients resulted in higher levels of blood glucose, urine acid, triglyceride (TG), and immune cells (leucocyte, neutrophil leucocyte) when compared to clinically diagnosed references, while circulating apolipoprotein A1 (Apob A1) and fatty acid binding protein 4 (FABP4) were reduced without visible drug-induced liver injury (DILI)...

BACKGROUND: Valproate (VPA) as a first-line antiepileptic drug is useful for the most types of epileptic seizure treatment. Previous studies observed that VPA influenced one-carbon metabolism (OCM), consequently, DNA methylation. However, other individual genetic variations, as well as VPA, modify DNA methylation. OBJECTIVE: In this study, we investigated associations between genetic variations in OCM and leukocyte DNA methylation in VPA-treated patients with epilepsy...
