Since the SCN1A protein is expressed predominately in GABAergic interneurons as opposed to excitatory pyramidal neurons, Dravet syndrome is considered a genetic dysfunction of inhibitory interneurons [8], [11]. 1.2. clinical trials with SSRIs should be considered in Dravet syndrome and other types of epilepsy. strong class=”kwd-title” Abbreviations: AED, antiepileptic drug; SSRI, selective serotonin reuptake inhibitor; SCN1A, sodium-channel gene alpha subunit; SMEI, severe myoclonic epilepsy of infancy; GEF?+, genetic epilepsy with febrile seizures plus strong class=”kwd-title” Keywords: Dravet syndrome, Seizures, Epilepsy, Serotonin, Selective serotonin reuptake inhibitor, Antidepressant 1.?Introduction Dravet syndrome is Mouse monoclonal to CD62P.4AW12 reacts with P-selectin, a platelet activation dependent granule-external membrane protein (PADGEM). CD62P is expressed on platelets, megakaryocytes and endothelial cell surface and is upgraded on activated platelets.This molecule mediates rolling of platelets on endothelial cells and rolling of leukocytes on the surface of activated endothelial cells an epileptic encephalopathy, which was first described in 1978 [1], [2]. It is a spectrum of conditions with variability in severity and manifestations but usually with catastrophic consequences [3]. 1.1. Etiology Mutations in the voltage-gated sodium-channel gene alpha subunit (SCN1A) were discovered in an epileptic syndrome called genetic epilepsy with febrile seizures plus (GEF?+) including some patients with severe myoclonic epilepsy of infancy (SMEI) in GEF?+ families [4], [5], [6]. Later, new SCN1A mutations were found in nonfamilial SMEI [7]; these mutations were de novo and more severe than those associated with GEF?+ [8]. Because some patients with the epileptic encephalopathy do not exhibit myoclonus, the disorder is now known as Dravet syndrome. Approximately 90% of patients with Dravet syndrome have de novo mutations, about 75% of patients with Dravet syndrome have mutations in the gene encoding SCN1A, and over 300 SCN1A mutations on chromosome 2q24 have been found [8], [9]. Other genes implicated in Dravet syndrome include PCDH19, GABRG2, and SCN1B [8]. Animal models exhibit the characteristic temperature/age dependent seizures seen in humans, and there is a 50% reduction in sodium current in heterozygous SCN1A mutations [10]. Since the SCN1A protein is expressed predominately in GABAergic interneurons as opposed to excitatory pyramidal neurons, Dravet syndrome is considered a genetic dysfunction of inhibitory interneurons [8], [11]. 1.2. Clinical manifestations Onset is typically in the first year of life in a previously healthy infant who experiences a seizure associated with fever, vaccination, or illness [8]. Initial seizures are generalized or hemiclonic, and the first seizure may be status epilepticus. Over the next few years, other seizure types usually develop, which may include atypical absence, focal (with impaired consciousness), myoclonic, atonic, and tonic seizures and convulsive or nonconvulsive status. Seizures may be triggered by fever, fatigue, photosensitivity, or excitement [2]. By the age of 2?years, developmental delay is usually apparent. Deterioration occurs from ages 1 to 4?years with the occurrence of psychomotor, behavioral, and gait abnormalities [2]. After age 5, convulsive seizures usually decrease and may happen primarily in sleep [2]. Cognitive and behavioral problems stabilize and may improve to a degree, but at least half of individuals remain seriously impaired. Magnetic resonance imaging shows only diffuse atrophy, and EEG may have diffuse slowing with generalized spike and polyspike and wave discharges and/or multifocal epileptiform discharges [8]. The seizures are typically medically resistant. Carbamazepine, lamotrigine, and phenytoin may exacerbate seizures. Valproate, benzodiazepines, stiripentol, and topiramate are the most effective antiepileptic drugs. However, seizures persist into adulthood [8]. Mortality is about 15% by adulthood in individuals with Dravet syndrome [8]. 2.?Case statement The case statement described here was carried out in accordance with the Code of Ethics of the World Medical Association (Declaration of Helsinki). DL is definitely a 27-year-old female with Dravet syndrome. She has a confirmed SCN1A mutation with deletion of 1 1?bp of C nucleotide position 1650, codon 550. Her 1st seizure occurred at age 4?weeks after a diphtheriaCpertussisCtetanus vaccination without fever; it consisted of some left-arm jerks. She experienced her 1st convulsion at age 6?months and her first episode of status epilepticus at age 3?years after which her development was noted to be distinctly abnormal. Over the years, DL suffered from multiple seizure types including generalized tonicCclonic, focal (with impaired consciousness), and myoclonic seizures and atonic drop attacks. Seizures were improved with fever and later on inside a catamenial pattern. Her seizures failed to improve with multiple antiepileptic medicines including carbamazepine, clobazam, clonazepam, clorazepate, felbamate, lamotrigine, levetiracetam, lorazepam, phenobarbital, phenytoin, primidone, retigabine, stiripentol, tiagabine, topiramate, valproate, and zonisamide. A rigid ketogenic diet and vagal nerve activation also failed to improve her seizures. Magnetic resonance imaging showed only diffuse atrophy. Electroencephalograms and video-EEGs exposed multifocal spikes and polyspikes interictally, and recorded generalized tonicCclonic seizures experienced ictal onsets with diffuse decrement. Her genetic diagnosis was made at age 21?years. In late July 2009, DL was started on fluoxetine 20?mg daily in an attempt to reduce stereotypic actions characterized as strenuous back-and-forth head shaking, which was sometimes associated with facial grimace and raising of her legs into a flexed position. These behaviors occurred multiple times per day but did.However, seizures persist into adulthood [8]. severity and manifestations but usually with catastrophic effects [3]. 1.1. Etiology Mutations in the voltage-gated sodium-channel gene alpha subunit (SCN1A) were discovered in an epileptic syndrome called genetic epilepsy with febrile seizures plus (GEF?+) including some individuals with severe myoclonic epilepsy of infancy (SMEI) in GEF?+ family members [4], [5], [6]. Later on, fresh SCN1A mutations were found in nonfamilial SMEI [7]; these mutations were de novo and more severe than those associated with GEF?+ [8]. Because some individuals with the epileptic encephalopathy do not show myoclonus, the disorder is now known as Dravet syndrome. Approximately 90% of individuals with Dravet syndrome possess de novo mutations, about 75% of individuals with Dravet syndrome possess mutations in the gene encoding SCN1A, and over 300 SCN1A mutations on chromosome 2q24 have been found [8], [9]. Additional genes implicated in Dravet syndrome include PCDH19, GABRG2, and SCN1B [8]. Animal models show the characteristic heat/age dependent seizures seen in humans, and there is a 50% reduction in sodium current in heterozygous SCN1A mutations [10].

Over the next few years, other seizure types usually develop, which may include atypical absence, focal (with impaired consciousness), myoclonic, atonic, and tonic seizures and convulsive or nonconvulsive status. Seizures may be brought on by fever, fatigue, photosensitivity, or enjoyment [2]. By the age of 2?years, developmental delay is usually apparent. Deterioration occurs from ages 1 to 4?years with the occurrence of psychomotor, behavioral, and gait abnormalities [2]. After age 5, convulsive seizures usually decrease and may occur mainly in sleep [2].

DL is usually a 27-year-old woman with Dravet syndrome. She has a confirmed SCN1A mutation with deletion of 1 1?bp of C nucleotide position 1650, codon 550. Her first seizure occurred at age 4?months after a diphtheriaCpertussisCtetanus vaccination without fever; it consisted of some left-arm jerks. She had her first convulsion at age 6?months and her first episode of status epilepticus at age 3?years after which her development was noted to be distinctly abnormal. Over the years, DL suffered from multiple seizure types including generalized tonicCclonic, focal (with impaired consciousness), and myoclonic seizures and atonic drop attacks. Seizures were increased with fever and later in a catamenial pattern. Her seizures failed to improve with multiple antiepileptic drugs including carbamazepine, clobazam, clonazepam, clorazepate, felbamate, lamotrigine, levetiracetam, lorazepam, phenobarbital, phenytoin, primidone, retigabine, stiripentol, tiagabine, topiramate, valproate, and zonisamide. A rigid ketogenic diet and vagal nerve stimulation also failed to improve her seizures. Magnetic resonance imaging showed only diffuse atrophy. Electroencephalograms and video-EEGs revealed multifocal spikes and polyspikes interictally, and recorded generalized tonicCclonic seizures had ictal onsets with diffuse decrement. Her genetic diagnosis was made at age 21?years. In late July 2009, DL was started on fluoxetine 20?mg daily in an attempt to reduce stereotypic actions characterized as vigorous back-and-forth head shaking, which was sometimes associated with facial grimace and raising of her legs into a flexed position. These behaviors occurred multiple times per day but did not occur out of sleep. The family thought that they could sometimes be interrupted with distraction. At the time, DL’s medications included felbamate (2400?mg/day), levetiracetam (1000?mg/day; higher dosages were ineffective and caused behavioral problems), diazepam PR PRN, lorazepam PO PRN, fexofenadine PRN,.Other genes implicated in Dravet syndrome include PCDH19, GABRG2, and SCN1B [8].

Clinical manifestations Starting point is normally in the 1st year of existence inside a previously healthful infant who encounters a seizure connected with fever, vaccination, or disease [8]. Preliminary seizures are generalized or hemiclonic, as well as the 1st seizure could be position epilepticus. Over another few years, additional seizure types generally develop, which might include atypical lack, focal (with impaired awareness), myoclonic, atonic, and tonic seizures and convulsive or nonconvulsive position. Seizures could be activated by fever, exhaustion, photosensitivity, or exhilaration [2]. By age 2?years, developmental hold off is normally apparent. Deterioration happens from age groups 1 to 4?years using the event of psychomotor, behavioral, and gait abnormalities [2]. After age group 5, convulsive seizures generally decrease and could occur primarily in rest [2]. Cognitive and behavioral complications stabilize and could improve to a qualification, but at least fifty percent of individuals remain seriously impaired.

Etiology Mutations in the voltage-gated sodium-channel gene alpha subunit (SCN1A) had been discovered within an epileptic symptoms called hereditary epilepsy with febrile seizures plus (GEF?+) including some sufferers with serious myoclonic epilepsy of infancy (SMEI) in GEF?+ households [4], [5], [6]. Afterwards, brand-new SCN1A mutations had been found in non-familial SMEI [7]; these mutations had been de novo and more serious than those connected with GEF?+ [8]. Because some sufferers using the epileptic encephalopathy usually do not display myoclonus, the disorder is currently referred to as Dravet symptoms. Around 90% of sufferers with Dravet symptoms have got de novo mutations, about 75% of sufferers with Dravet symptoms have got mutations in the gene encoding SCN1A, and over 300 SCN1A mutations on chromosome 2q24 have already been discovered [8], [9].
