Autoimmune epilepsy in children

C Nalli, A Iodice, L Andreoli, J Galli, A Lojacono, M Motta, E Fazzi, A Tincani
Background Systemic lupus erythematosus (SLE) and antiphospholipid antibody syndrome (APS) are autoimmune diseases that affect women of childbearing age. Maternal IgG antiphospholipid antibodies (aPL) can cross the placenta during pregnancy and theoretically reach the fetal brain. Some studies showed an increased number of learning disabilities in these children. Objectives To evaluate the long-term neurodevelopmental outcome of 40 children (median age 7.4 years) born to mothers with SLE and/or APS carrying positive IgG aPL during the third trimester of pregnancy...

PURPOSE: Because immune mediated mechanisms are suspected in epileptogenesis, IVIg and corticosteroids have been used as alternatives to treat refractory seizures. We present our experience treating intractable epileptic children with IVIg and prednisone. METHODS: Children with intractable epilepsy treated with prednisone or IVIg between 2005-2016 were reviewed retrospectively. Children with infantile spasms and autoimmune epilepsy were excluded. Data analyzed include epilepsy type and etiology, duration of epilepsy prior to treatment, seizure outcome, time to best seizure outcome, and adverse effects...

AIM: Intravenous immunoglobulin (IVIG) is an expensive therapy used in immunodeficiency and autoimmune disorders. Increasing demands and consequent shortages result in a need for usage to conform to guidelines. METHOD: We retrospectively evaluated IVIG use for neuroimmunological indications and adherence to existing guidelines in a major Australian paediatric hospital between 2000 and 2014. RESULTS: One-hundred and ninety-six children (96 male, 100 female; mean age at disease onset 6y 5mo [range 3mo-15y 10mo], mean age at first IVIG dose 7y 2mo [range 3mo-16y 5mo]) received IVIG for neuroimmunological indications during the study period (28...

Voltage-gated potassium channel (VGKC)-complex antibodies are defined by the radioimmunoprecipitation of Kv1 potassium channel subunits from brain tissue extracts and were initially discovered in patients with peripheral nerve hyperexcitability (PNH). Subsequently, they were found in patients with PNH plus psychosis, insomnia, and dysautonomia, collectively termed Morvan's syndrome (MoS), and in a limbic encephalopathy (LE) with prominent amnesia and frequent seizures. Most recently, they have been described in patients with pure epilepsies, especially in patients with the novel and distinctive semiology termed faciobrachial dystonic seizures (FBDS)...

Multiple factors such as genetic and extraneous causes (drugs, toxins, adverse psychological events) contribute to neuro-psychiatric conditions. In a subgroup of these disorders, systemic folate deficiency has been associated with macrocytic anemia and neuropsychiatric phenotypes. In some of these, despite normal systemic levels, folate transport to the brain is impaired in the so-called cerebral folate deficiency (CFD) syndromes presenting as developmental and psychiatric disorders. These include infantile-onset CFD syndrome, infantile autism with or without neurologic deficits, a spastic-ataxic syndrome and intractable epilepsy in young children expanding to refractory schizophrenia in adolescents, and finally treatment-resistant major depression in adults...

Nonrapid eye movement (NREM) or arousal parasomnias are prevalent conditions in children and young adults, apparently provoked by any medical, physical, mental, or pharmacologic/toxic agent disturbing normal biorhythm and causing sleep fragmentation or abundant amount of slow wave sleep. The nadir and the ascending slope of the first sleep cycle of night sleep are the typical periods when NREM parasomnias, especially sleepwalking may occur on sleep-microstructural level; microarousals are the typical moments allowing NREM parasomnias...

PURPOSE OF REVIEW: Autoimmune epileptic encephalopathy is a potentially treatable neurological syndrome characterized by the coexistence of a neuronal antibody in serum and, often, cerebrospinal fluid. Patients present with combinations of seizures, neuropsychiatric features, movement disorder, and cognitive decline, but some patients have isolated seizures either at first presentation or during their illness. This review summarizes our current understanding of the roles of specific neuronal antibodies in epilepsy-related syndromes and aims to aid the clinician in diagnosis and treatment...

BACKGROUND: A syndrome of young-onset diabetes mellitus associated with microcephaly, epilepsy and intellectual disability caused by mutations in the tRNA methyltransferase 10 homologue A (TRMT10A) gene has recently been described. CASE REPORT: We report two siblings from the fourth family reported to have diabetes mellitus as a result of a TRMT10A mutation. A homozygous nonsense mutation p.Glu27Ter in TRMT10A was identified using targeted next-generation sequencing and confirmed by PCR/Sanger sequencing...

Though the mechanisms of action of intravenous immunoglobulins (IVIG) are not completely understood, these drugs are widely used in treatment of autoimmune diseases. In this review, we have analyzed the literature on the use of IVIG in the treatment of autoimmune diseases of the nervous system in children and discuss the management of patients basing on the recommendation of the European Federation of Neurological Societies. The efficacy of IVIG in children has been shown as first line treatment in Guillain-Barre syndrome, chronic inflammatory demyelinating polyneuropathy, multifocal motor neuropathy, dermatomyositis as a second-line drug in the combination with prednisolone or immunosuppressors in patients refractory to treatment with corticosteroids and cytostatics, myasthenic crisis in myasthenia gravis, exacerbations and short-term treatment of severe forms, non-responsiveness to acetylcholinesterase inhibitors, multiple sclerosis as second or third line of treatment in patients with relapsing-remitting course with intolerance to standard immunomodulatory therapy, acute multiple encephalomyelitis with no response to the treatment with high doses of corticosteroids, paraneoplastic syndromes, pharmacoresistant epilepsy and autoimmune encephalitis...

BACKGROUND: Anti-Ma2-associated encephalitis is a rare paraneoplastic neurological syndrome characterized by isolated or combined limbic, diencephalic, or brainstem dysfunction. It is rarely reported in children. CASE STUDY: We describe the clinical data of a 2-year-old girl referred to our department for refractory focal seizures associated with fever, followed by behavioural changes, speech disturbances and confusional episodes. Brain magnetic resonance imaging (MRI) showed left temporoparietal brain involvement...

INTRODUCTION: Psychotic manifestations in childhood are not infrequent, yet the existing literature dealing with the neurological appraisal of children and adolescents with a clinical picture of psychosis is very scant. AIM: To conduct a non-systematic review of the literature that provides an answer to these three questions: When must a neurological appraisal be performed in a child with psychotic traits? What medical conditions can include signs and symptoms of psychosis in their development? And, what diagnostic procedure should be followed? DEVELOPMENT: The diseases that can present psychotic symptoms at onset or during their course are reviewed and grouped by pathologies: inborn errors of metabolism, genetic diseases, autoimmune and infectious diseases, malformations of the central nervous system, epilepsy, vascular pathology, rheumatologic processes, brain tumours, and psychoactive substances and drugs...

UNLABELLED: Linear scleroderma en coup the sabre (LSCS), progressive facial hemiatrophy (PFH) and autoimmune encephalitis are distinct clinical entities, although patients with overlapping features have been reported. We performed a multicenter retrospective review of a series of children with LSCS and/or PFH to explore the relation between these entities. The files of 16 children were reviewed, 11 presented with LSCS, 5 with PFH, with time overlapping cutaneous features were seen. Extracutaneous signs were found in both groups...

Autoimmunity and inflammation have been implicated as causative factors of seizures and epilepsy. Autoimmune disorders can affect the central nervous system as an isolated syndrome or be part of a systemic disease. Examples of systemic autoimmune disorders include systemic lupus erythematosus, antiphospholipid syndrome, rheumatic arthritis, and Sjögren syndrome. Overall, there is a 5-fold increased risk of seizures and epilepsy in children with systemic autoimmune disorders. Various etiologic factors have been implicated in causing the seizures in these patients, including direct inflammation, effect on blood vessels (vasculitis), and production of autoantibodies...

There is emerging interest in autoimmune epilepsy, which represents a small but potentially treatable form of epilepsy. Most insights into autoimmune epilepsy derive from the recent descriptions of autoimmune encephalitis that takes two general forms: a focal encephalitis (such as limbic) or a diffuse encephalitis (such as anti-N-methyl-D-aspartate receptor [NMDAR] encephalitis). The features of autoimmune epilepsy include acute or subacute onset of seizures, usually in the context of encephalopathy, and inflammation of the central nervous system on testing cerebrospinal fluid or magnetic resonance imaging...

Status epilepticus (SE) is a medical emergency with increased risk of morbidity and mortality in all age groups. Recent research has identified a variety of new genes implicated in disorders with severe epilepsies as a prominent feature. Autoimmune mechanisms have also been recently recognised as a cause of epilepsies with SE as a characteristic symptom. Knowledge about the aetiology potentially underlying SE may help to guide diagnostics and eventually influence treatment decisions. This review recapitulates, in brief, the risk of SE in specific clinical settings, provides an overview of paediatric epilepsy syndromes more commonly, or by definition, associated with SE, and summarizes some recent research data on genetic defects and disease mechanisms implicated in the pathogenesis of epilepsies frequently accompanied by SE...

A wide range of clinical presentations including neuromuscular disorders and autoimmune encephalopathies is being recognized to be associated with various autoantibodies. Glycine receptor (GlyR) antibodies have so far been found mainly in adult patients with phenotypes comprising progressive encephalomyelitis with rigidity and myoclonus or stiff-person syndrome. We report a four-year-old boy who presented with a two-year-history of drug-resistant focal epilepsy with unusual seizure semiology, temper tantrums, headache, clumsiness, and intermittently impaired speech...

Gender differences in the incidence and clinical course of acquired and "cryptogenic" epilepsy are reviewed based on a literature search. We emphasized incidence and population-based studies because they are best suited to assess the effect of gender on susceptibility and clinical evolution of these epilepsies and may control for potential confounding factors. However, such studies were only available for a few acquired etiologies. These included tumor, prenatal and perinatal brain insults, cerebrovascular disease, infection, trauma, neurodegenerative disease, and autoimmune disorders...
