Activated human T cells, B cells, and monocytes produce brain-derived neurotrophic factor in vitro and in inflammatory brain lesions: a neuroprotective role of inflammation? (1/1379)

Brain-derived neurotrophic factor (BDNF) has potent effects on neuronal survival and plasticity during development and after injury. In the nervous system, neurons are considered the major cellular source of BDNF. We demonstrate here that in addition, activated human T cells, B cells, and monocytes secrete bioactive BDNF in vitro. Notably, in T helper (Th)1- and Th2-type CD4(+) T cell lines specific for myelin autoantigens such as myelin basic protein or myelin oligodendrocyte glycoprotein, BDNF production is increased upon antigen stimulation. The BDNF secreted by immune cells is bioactive, as it supports neuronal survival in vitro. Using anti-BDNF monoclonal antibody and polyclonal antiserum, BDNF immunoreactivity is demonstrable in inflammatory infiltrates in the brain of patients with acute disseminated encephalitis and multiple sclerosis. The results raise the possibility that in the nervous system, inflammatory infiltrates have a neuroprotective effect, which may limit the success of nonselective immunotherapies.  (+info)

Serum gelatinase B, TIMP-1 and TIMP-2 levels in multiple sclerosis. A longitudinal clinical and MRI study. (2/1379)

Metalloproteinases have been implicated in the pathogenesis of multiple sclerosis. We report longitudinal serum levels of gelatinase B and of the tissue inhibitors of matrix metalloproteinases (TIMP), TIMP-1 and TIMP-2, in 21 patients with relapsing multiple sclerosis. Patients had monthly clinical and gadolinium-enhanced MRI follow-up for 10 months. Longitudinal samples in nine healthy controls and cross-sectional samples from 12 patients with inflammatory CNS disease and 15 patients with other neurological diseases were used for comparison. Average serum gelatinase B, TIMP-1 and TIMP-2 levels were significantly higher in multiple sclerosis patients and those with other neurological diseases than in healthy controls. In the patients with multiple sclerosis, gelatinase B levels were significantly higher during clinical relapse compared with periods of clinical stability. Multiple sclerosis patients with high mean serum gelatinase B levels had significantly more T1-weighted gadolinium-enhancing MRI lesions than those with mean levels within the control range. TIMP-1 levels were not different during relapse and between relapses. There was a trend for TIMP-2 levels to be lower during relapse compared with non-relapse periods. For similar levels of serum gelatinase B, associated TIMP-1 levels were significantly lower and TIMP-2 levels significantly higher in multiple sclerosis patients compared with the inflammatory CNS control group. We propose that an abnormality in the inhibitory response to metalloproteinases may play an aetiological role in the chronicity of multiple sclerosis.  (+info)

Progressive multifocal leukoencephalopathy after autologous bone marrow transplantation and alpha-interferon immunotherapy. (3/1379)

A patient with a stage IV mantle cell lymphoma (according to the REAL classification) was treated with high-dose chemotherapy and autologous bone marrow transplantation. One year later while on alpha-interferon immunotherapy she suffered from progressive loss of short-term memory and reported difficulties in recognizing objects. Magnetic resonance imaging (MRI) showed a vast ring-enhancing lesion of the left postcentral parietal area. Serial stereotactic biopsies disclosed progressive multifocal leukoencephalopathy without JC-virus in the cerebrospinal fluid. Therapy with subcutaneous interleukin-2 (IL-2) every other day and intrathecal cytarabine once a week was started. After 4 weeks the patient refused further treatment. Nevertheless her condition improved over the next 8 months and MRI scans showed a marked improvement in the lesions.  (+info)

Inhibition of inducible nitric oxide synthase exacerbates chronic cerebral toxoplasmosis in Toxoplasma gondii-susceptible C57BL/6 mice but does not reactivate the latent disease in T. gondii-resistant BALB/c mice. (4/1379)

Infection of C57BL/6 mice with Toxoplasma gondii leads to progressive and ultimately fatal chronic Toxoplasma encephalitis (TE). Genetic deletion or inhibition of inducible nitric oxide synthase (iNOS) from the beginning of infection increased the number of T. gondii cysts in the brain and markedly reduced the time-to-death in this mouse strain. In the present study, we addressed whether iNOS also contributes to the control of intracerebral parasites in a clinically stable latent infection that develops in T. gondii-resistant BALB/c mice after resolution of the acute phase of TE. iNOS was expressed in the inflammatory cerebral infiltrates of latently infected BALB/c mice, but the number of iNOS+ cells was significantly lower than in the brains of chronically infected T. gondii-susceptible C57BL/6 mice. In BALB/c mice with latent TE (> 30 days of infection), treatment with the iNOS inhibitors L-N6-iminoethyl-lysine or L-nitroarginine-methylester for < or = 40 days did not result in an increase of the intracerebral parasitic load and a reactivation of the disease, despite the presence of iNOS-suppressive inhibitor levels in the brain. However, L-nitroarginine-methylester treatment had remarkably toxic effects and induced a severe wasting syndrome with high mortality. In contrast to BALB/c mice, L-N6-iminoethyl-lysine treatment rapidly exacerbated the already established chronic TE of C57BL/6 mice. Thus, the containment of latent toxoplasms in T. gondii-resistant BALB/c mice is independent of iNOS, whereas the temporary control of intracerebral parasites in T. gondii-susceptible C57BL/6 mice with chronic TE requires iNOS activity.  (+info)

Acute hemorrhagic leukoencephalitis in patients with acute myeloid leukemia in hematologic complete remission. (5/1379)

The authors describe the cases of three patients affected by acute myeloid leukemia, in complete remission, who rapidly developed neurologic symptoms leading to death. Neither clinical characteristics, nor radiological or microbiological procedures, allowed an etiological diagnosis of the neurologic syndrome. Post-mortem examination of the brain showed both macroscopic and microscopic findings compatible with acute hemorrhagic leukoencephalitis. The difficulty in distinguishing this entity from other CNS disease-related complications (e.g. leukemia infiltration, drug toxicity, hemorrhages) should not lead to an underestimation of the true incidence of this complication. We believe that with more attention to the possibility of this complication there would probably be both a greater possibility of collecting clinical informations about the real impact of this dramatic disease and a stronger hope of finding the right treatment for it.  (+info)

Serum antibodies to Balamuthia mandrillaris, a free-living amoeba recently demonstrated to cause granulomatous amoebic encephalitis. (6/1379)

Free-living amoebae cause three well-defined disease entities: a rapidly fatal primary meningoencephalitis, a chronic granulomatous amoebic encephalitis (GAE), and a chronic amoebic keratitis. GAE occurs in immunocompromised persons. Recently, another type of free-living amoeba, Balamuthia mandrillaris, has been shown to cause GAE. The finding that this amoeba has caused infection in some healthy children has raised the possibility that humans may lack immunity to B. mandrillaris. Human serum was examined for the presence of surface antibodies specific for this amoeba by immunofluorescence. Sera from adults contained titers of 1/64-1/256 of anti-B. mandrillaris antibodies (IgM and IgG classes), which did not cross-react with other amoebae. Cord blood contained very low antibody levels, but levels similar to those in adults were seen in serum of 1- to 5-year-old children.  (+info)

MR line scan diffusion imaging of the brain in children. (7/1379)

BACKGROUND AND PURPOSE: MR imaging of the self-diffusion of water has become increasingly popular for the early detection of cerebral infarction in adults. The purpose of this study was to evaluate MR line scan diffusion imaging (LSDI) of the brain in children. METHODS: LSDI was performed in four volunteers and 12 patients by using an effective TR/TE of 2736/89.4 and a maximum b value of 450 to 600 s/mm2 applied in the x, y, and z directions. In the volunteers, single-shot echo planar imaging of diffusion (EPID) was also performed. The patients (10 boys and two girls) ranged in age from 2 days to 16 years (average age, 6.6 years). Diagnoses included acute cerebral infarction, seizure disorder, posttraumatic confusion syndrome, complicated migraine, residual astrocytoma, encephalitis, hypoxia without cerebral infarction, cerebral contusion, and conversion disorder. In all patients, routine spin-echo images were also acquired. Trace images and apparent diffusion coefficient maps were produced for each location scanned with LSDI. RESULTS: In the volunteers, LSDI showed less chemical-shift and magnetic-susceptibility artifact and less geometric distortion than did EPID. LSDI was of diagnostic quality in all studies. Diffusion abnormalities were present in five patients. Restricted diffusion was present in the lesions of the three patients with acute cerebral infarction. Mildly increased diffusion was present in the lesions of encephalitis and residual cerebellar astrocytoma. No diffusion abnormalities were seen in the remaining seven children. CONCLUSION: LSDI is feasible in children, provides high-quality diffusion images with less chemical-shift and magnetic-susceptibility artifact and less geometric distortion than does EPID, and complements the routine MR examination.  (+info)

Molecular characterization of the myxosporean associated with parasitic encephalitis of farmed Atlantic salmon Salmo salar in Ireland. (8/1379)

During seasonal epizootics of neurologic disease and mass mortality in the summers of 1992, 1993 and 1994 on a sea-farm in Ireland, Atlantic salmon Salmo salar smolts suffered from encephalitis associated with infection by a neurotropic parasite. Based on ultrastructural studies, this neurotropic parasite was identified as an intercellular presporogonic multicellular developmental stage of a histozoic myxosporean, possibly a Myxobolus species. In order to generate sequence data for phylogenetic comparisons to substantiate the present morphological identification of this myxosporean in the absence of detectable sporogony, polymerase chain reaction (PCR), Southern blot hybridization, dideoxynucleotide chain-termination DNA sequencing, and in situ hybridization (ISH) were used in concert to characterize segments of the small subunit ribosomal RNA (SSU rRNA) gene. Oligonucleotide primers were created from sequences of the SSU rRNA gene of M. cerebralis and were employed in PCR experiments using DNA extracted from formalin-fixed paraffin-embedded tissue sections of brains from Atlantic salmon smolts in which the myxosporean had been detected by light microscopy. Five segments of the SSU rRNA gene of the myxosporean, ranging in length from 187 to 287 base pairs, were amplified, detected by hybridization with sequence-specific probes, and sequenced. Consensus sequences from these segments were aligned to create a partial sequence of the SSU rRNA gene of the myxosporean. Assessments of sequence identity were made between this partial sequence and sequences of SSU rRNA genes from 7 myxosporeans, including Ceratomyxa shasta, Henneguya doori, M. arcticus, M. cerebralis, M. insidiosus, M. neurobius, and M. squamalis. The partial SSU rRNA gene sequence from the myxosporean had more sequence identity with SSU rRNA gene sequences from neurotropic and myotropic species of Myxobolus than to those from epitheliotropic species of Myxobolus or Henneguya, or the enterotropic species of Ceratomyxa, and was identical to regions of the SSU rRNA gene of M. cerebralis. Digoxigenin-labeled oligonucleotide DNA probes complementary to multiple segments of the SSU rRNA gene of M. cerebralis hybridized with DNA of the parasite in histologic sections of brain in ISH experiments, demonstrating definitively that the segments of genome amplified were from the organisms identified by histology and ultrastructural analysis. Based on sequence data derived entirely from genetic material of extrasporogonic stages, the SSU rDNA sequence identity discovered in this study supports the hypothesis that the myxosporean associated with encephalitis of farmed Atlantic salmon smolts is a neurotropic species of the genus Myxobolus, with sequences identical to those of M. cerebralis.  (+info)

Rasmussens encephalitis, also known as chronic focal encephalitis (CFE), is a rare inflammatory neurological disease, characterized by frequent and severe seizures, loss of motor skills and speech, hemiparesis (weakness on one side of the body), encephalitis (inflammation of the brain), and dementia. The illness affects a single cerebral hemisphere and generally occurs in children under the age of 15. The condition mostly affects children, with an average age of 6 years. However, one in ten people with the condition develops it in adulthood. There are two main stages, sometimes preceded by a prodromal stage of a few months. In the acute stage, lasting four to eight months, the inflammation is active and the symptoms become progressively worse. These include weakness of one side of the body (hemiparesis), loss of vision for one side of the visual field (hemianopia), and cognitive difficulties (affecting learning, memory or language, for example). Epileptic seizures are also a major part of the ...

Brain infections such as meningitis and encephalitis are highly debilitating diseases, and an accurate diagnostic is essential to give patients the best treatment available. For cryptococcal meningitis, clinical trials focus on prevention, for an early diagnosis, and novel ways to use existing treatments or repurpose old drugs.
Today is World Encephalitis Day - the global awareness day for people who have been affected by encephalitis. Founded by The Encephalitis Society in 2014, the day has subsequently helped to raise awareness among millions of people. This year the society is aiming to shine a light on this devastating condition which affects 500,000 people each year by illuminating iconic landmarks, local buildings and homes across the globe. While we are unable to light up our own offices, we are proud to help spread the word about encephalitis.. Encephalitis is an inflammation of the brain. The inflammation is caused either by an infection invading the brain (infectious); or through the immune system attacking the brain in error (post-infectious or autoimmune Encephalitis). Some types of encephalitis are spread by mosquitoes (such as Japanese encephalitis), ticks (such as tick-borne encephalitis) and mammals (such as rabies).. Encephalitis sometimes starts off with flu-like symptoms, such as a high temperature ...
The RE Childrens Project was founded in 2010 to increase awareness regarding Rasmussens Encephalitis (RE) for the primary purpose of supporting scientific research directed towards a cure.
World Encephalitis Day is held on February 22 each year and is designed to raise awareness of encephalitis, an inflammation of the brain. The global awareness day was created by The Encephalitis Society, a UK registered charity, and announced in October 2013. The inaugural World Encephalitis Day operated under the tagline, Make Today your First, and highlighted the fact that many people would hear about encephalitis for the first time in a hospital waiting room. Supporters were encouraged to share information on encephalitis to raise awareness globally. One of those supporters was Simon Hattenstone, a survivor of encephalitis and journalist with The Guardian, who wrote: Encephalitis is such a cruel disease because it is often misdiagnosed - even today. And that delay in diagnosis can have fatal consequences. The Society teamed up with the Institute of Infection and Global Health at the University of Liverpool to break a world record for the largest human image of an organ when 687 people ...
1 the world mourned the death of Knut the polar bear, who had stolen the hearts of everyone who had visited the Berlin Zoo or who had followed his high profile career of modeling alongside celebrities like Leonardo DiCaprio. In 2012, Sussanah Calahan released her memoir Brain on Fire: My Month of Madness, which chronicled her struggle with NMDA receptor mediated-encephalitis. It was soon discovered that the same disease that Sussanah Calahan wrote about was the very disease that resulted in the death of Knut the bear. In this blog we will discuss what encephalitis is, and more specifically what NMDA receptor mediated encephalitis is. What is encephalitis?. Very simply put, encephalitis is a sudden onset inflammation of the brain or regions of the brain. While relatively rare, the incidence of the disease varies throughout the world, with approximately 7.4 new cases of acute encephalitis per 100,000 per year in the Western countries. Patients with encephalitis can present with a variety of ...
BACKGROUND: Encephalitis has many causes, but for most patients the cause is unknown. We aimed to establish the cause and identify the clinical differences between causes in patients with encephalitis in England. METHODS: Patients of all ages and with symptoms suggestive of encephalitis were actively recruited for 2 years (staged start between October, 2005, and November, 2006) from 24 hospitals by clinical staff. Systematic laboratory testing included PCR and antibody assays for all commonly recognised causes of infectious encephalitis, investigation for less commonly recognised causes in immunocompromised patients, and testing for travel-related causes if indicated. We also tested for non-infectious causes for acute encephalitis including autoimmunity. A multidisciplinary expert team reviewed clinical presentation and hospital tests and directed further investigations. Patients were followed up for 6 months after discharge from hospital. FINDINGS: We identified 203 patients with encephalitis. Median
Encephalitis is inflammation of the brain. It is usually caused by a viral infection. Examples of viral infections that can cause encephalitis include herpes simplex virus (the virus that causes cold sores and genital herpes), varicella zoster virus (the chickenpox virus), mumps virus, measles virus and flu viruses. Most cases of encephalitis are caused by the virus directly infecting the brain. However, sometimes encephalitis can develop if your immune system tries to fight off a virus and, at the same time, attacks the nerves in your brain in error. This is known as post-infectious or autoimmune encephalitis. What is the difference between encephalitis and meningitis?. Meningitis is an inflammation of the lining that covers the brain and spinal cord (the meninges). It is usually caused by a bacterial or viral infection. Sometimes you can have both encephalitis and meningitis at the same time. This is called meningoencephalitis.. You are also more likely to develop encephalitis if your immune ...
Encephalitis is a devastating condition whose impact upon people should not be underestimated. It robs people of abilities most of us take for granted, it leaves people without their loved ones, and even in those families where the person affected survives the person they once knew can be dramatically changed. Life After Encephalitis provides a unique insight into the experiences of those affected by encephalitis, sharing the rich, perceptive, and often powerful, narratives of survivors and family members. It shows how listening to patient and family narratives can help us to understand how they make sense of what has happened to them, and also help professionals better understand and engage with them in practice. The book will also be useful for considering narratives associated with brain injuries from other causes, for example traumatic brain injury. Life After Encephalitis will appeal to a wide range of professionals working in rehabilitation settings, and also to and survivors of encephalitis,

It could be the fact that in our work we deal with many people with acquired brain injuries, some with encephalitis, for whom we strive to secure compensation intended to improve quality of life. Yet we realise that it is only a very small proportion of those affected who we can help directly, not every person with encephalitis can bring a claim. Maybe supporting The Encephalitis Society is our way of giving a bit back to those who we cant help but we realise have exactly the same needs as our clients. Perhaps it is a combination of all of the above. Perhaps it doesnt matter why. As long as the end result is improved quality of life of all people affected directly and indirectly by Encephalitis, that in itself is enough ...

Autoimmune encephalitis associated with antibodies to leucine-rich glioma inactivated 1 (LGI1) is recently described and there is a lack of detailed reports on the treatment of relapsing or refractory cases and long-term outcomes. Two case reports are presented. Both cases had faciobrachial dystonic seizures (FBDS) and received rituximab after relapsing or refractory disease. Both cases achieved sustained clinical remission of up to 15 and 56 months respectively. Rituximab use allowed withdrawal of corticosteroids and was well tolerated. Randomized clinical trials are needed in LGI1 encephalitis and other autoimmune encephalitides.

Herpes simplex encephalitis is a severe viral infection of the central nervous system. Herpes simplex encephalitis may be classified according to origin of disease into two subtypes: oral (HSV-1) and genital (HSV-2). The exact pathogenesis of herpes simplex encephalitis is not fully understood.[1] Herpes simplex encephalitis must be differentiated from other diseases that cause fever, headache, and altered mental status. Physical examination findings for herpes simplex encephalitis are generally unspecific. Herpes simplex encephalitis constitutes a medical emergency. If left untreated, approximately 70% patients with herpes simplex encephalitis progress to mortality.[2] Common complications of herpes simplex encephalitis include meningitis, increased intracranial pressure, and coma. Laboratory findings consistent with the diagnosis of herpes simplex encephalitis include increased leukocytes in cerebrospinal fluid.[3] Polymerase chain reaction is critical in the diagnosis of herpes simplex ...
Hemispherotomy is the currently preferred surgical treatment option for refractory unihemispheric epilepsies. The incidence of hydrocephalus is greatly reduced in this disconnective procedure when compared with the resective procedure of anatomical hemispherectomy. We describe the occurrence of ipsilateral trapped lateral ventricle months after hemispherotomy for Rasmussens encephalitis. There is enough evidence to suggest that this rare and interesting complication is due to the local inflammatory changes associated with the surgical trauma. ...

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a well-defined autoimmune disorder. Hashimotos encephalopathy (HE) is a still controversial entity, lacking definite diagnostic criteria. We described a 14-year-old-girl presenting with a clinical picture consistent with the diagnosis of anti-NMDAR encephalitis, confirmed by NMDAR antibody testing. Four years earlier, she had presented a similar episode of acute encephalopathy diagnosed as HE. Anti-NMDAR encephalitis and HE share similar clinical features so that the differential diagnosis can be difficult if specific antibodies are not tested. The correct diagnosis of anti-NMDAR encephalitis is crucial to plan the appropriate management and follow-up, namely in term of oncological screening, since it can be paraneoplastic in origin. We suggest to re-evaluate the clinical history of all subjects with previous HE diagnosis in order to evaluate the possible diagnosis of anti-NMDAR encephalitis and plan the appropriate management of these patients

Rasmussen encephalitis (RE) is a devastating but important cause of medically intractable epilepsy in children, first described by Rasmussen et al in 1958 at the Montreal Neurological Institute. Since then, there has been progress in our understanding of the clinical evolution and pathology. However, progress in comprehending the underlying triggers, pathophysiology, and effective early therapies ...
Anti-epileptic drugs are frequently helpful but usually do not entirely control seizures. Recent studies have shown some success with treatments that suppress or modulate the immune system, in particular those that use corticosteroids, intravenous immunoglobulin, or tacrolimus. Surgery to control seizures may be recommended, particularly in children where recovery potential is high. Some centers suggest early surgery for RE as a way to treat the seizures and to take advantage of developmental neuroplasticy, where different parts of the brain learn new connections following injury or trauma. Surgical procedures, such as functional hemispherectomy (surgery to remove the part of the hemisphere where the seizures start) and functional hemispherotomy (surgically severing all connections between the right and left halves of the brain), may reduce the frequency of seizures and also improve behavior and cognitive abilities. ...

Investigators at Universities of Barcelona, Pennsylvania, Oviedo, and Valencia, and the Spanish NMDAR Encephalitis Work Group report the clinical features of 20 pediatric patients with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis seen in a single center in Spain in the last 4 years. Median patient age was 13 years (range, 8 months-18 years); 70% were female. Initial symptoms were neurologic (dyskinesias or seizures) in 12 (60%) and psychiatric in 40%. By one month after disease onset, all had involuntary movements and changes in behavior and speech. All patients received steroids, IV immunoglobulin or plasma exchange, and 7 rituximab or cyclophosphamide. At a median follow-up of 17.5 months, 85% had substantially recovered, 10% had moderate or severe deficits, and 1 had died. Three patients had previous episodes compatible with anti-NMDAR encephalitis, and 2 had additional relapses. Ovarian teratoma was identified in 2 patients (10%), 1 at disease onset and the other one-year later. A ...
Pearls Anti-NMDA receptor encephalitis can coexist with an overlapping demyelinating syndrome. An atypical presentation of a single autoimmune disorder should prompt investigation for coexistent autoimmune disorders. Discovery of overlap syndromes is important because the management and prognosis may be different. Oysters In autoimmune encephalitis, shorter time from symptom onset to treatment initiation has been associated with better outcome.1 Treatment should not be delayed until the result of autoantibody testing is available. Case report A 31-year-old man developed a subacute onset of headache, left-sided numbness, and anterograde amnesia. In the following 2 weeks, he experienced personality changes, anxiety, paranoid thoughts, 7 kg weight loss, and worsening cognitive changes. He said that he felt as though he was trapped in a time loop, meaning that events seemed to be constantly recurring to him. He denied fever, night sweats, viral prodromal symptoms, or recent vaccinations. He was ...
Background: Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a recently described life-threatening autoimmune disorder associated with a characteristic multi-stage neuropsychiatric syndrome. Although it is known that the majority of patients experience neuropsychological disturbance post-treatment, some aspects of the cognitive profile remain unclear. Methods: This study sought to investigate patterns of cognitive functioning in a sample of anti-NMDAR encephalitis patients. Seven (6F:1M; mean age, 26.4 years; range, 16-37 years) treated patients completed a comprehensive set of neurocognitive and social functioning measures. Performance was analyzed using normative data (where available), and comparison with matched controls (10F:4M; mean age, 25.8 years; range, 16-38 years). Results: Individual cognitive profiles ranged from within normal limits to extensive dysfunction. Relative to controls, the patient groups performance was affected in the domains of verbal/ visual memory, working ...
Encephalitis with antibodies against N-methyl D-aspartate receptor (NMDAR) is recognized as a group of antibody-mediated neuropsychiatric syndromes, which occurs with and without a tumor association. Neoplasm may contribute to the pathogenesis of Anti-NMDAR encephalitis in tumor-positive patients. However, the underlying causes in tumor-negative patients are largely unknown. This is the first report, of which we are aware, of two cases of anti-NMDAR encephalitis after the resection of melanocytic nevus. We describe 2 female patients in their 20s confirmed with anti-NMDAR encephalitis. They shared two points in common: About several weeks (2 weeks and 5 weeks respectively) before the initial symptom, both of them underwent a resection of melanocytic nevi; the screening tests for an ovarian teratoma and other tumors were all negative. A 25 year-old woman presented with seizure, psychiatric symptoms and behavioral change for 2 weeks. Electroencephalogram indicated electrographic seizures. Anti-NMDAR

In their JNNP paper, Shu et al investigated whether anti-NMDAR encephalitis was associated with any HLA alleles, utilising samples from 61 patients with anti-NMDAR encephalitis and 571 healthy controls from the Chinese Han population.4 In this study, six HLA loci (HLA-A, HLA-B, HLA-C, HLA-DRB1, HLA -DQA1 and HLA -DQB1) were typed using a PCR sequence-based typing method, while the German study mentioned above imputed HLA alleles from single nucleotide polymorphisms (SNPs) genotyped on a genome-wide SNP chip array.2 Shu et al demonstrated that the HLA-DRB1*16:02 allele was associated with disease susceptibility (allele frequency: 14.75% in cases vs 4.82% in controls; OR 3.42 (95% CI 1.82 to 6.17)) and the association did not depend on the positivity of tumours. Furthermore, the patients with anti-NMDAR encephalitis with HLA-DRB1*16:02 tended to respond less efficiently to treatment, suggesting that certain genetic backgrounds may contribute to distinct disease development.. Although replication ...
Anti-N-methyl-D-aspartate-receptor (NMDAR) encephalitis is a severe autoimmune condition, which typically affects young females. The long-term clinical consequences and brain morphology changes after anti-NMDAR encephalitis are not well known. We present clinical and neuroimaging follow-up data on a 25-year female patient with typically presenting anti-NMDAR encephalitis. Longitudinal analyses of brain morphology were done using 3 T structural magnetic resonance imaging (sMRI) and Freesurfer analysis at the time of diagnosis and after symptomatic remission. The presented case attained good functional recovery after standard immunoglobulin-corticosteroid treatment but elevated serum NMDAR antibody levels persisted. The patient had no symptomatic relapses during a 3-year clinical follow-up. In the baseline brain sMRI scan there were no marked volume changes. However, a follow-up sMRI after 9 months indicated clear volume reductions in frontal cortical regions compared to matched controls with identical

Chronic Focal Encephalitis (Rasmussens Encephalitis) is a condition characterized by a progressive hemiparesis, cognitive decline (including loss of language skills if the language dominant hemisphere is involved) and epileptic seizures that are typically refractory to medical treatment (Rasmussen). Attempts to control the seizures with anticonvulsants are ineffective and the only effective treatment to date is a hemispherectomy (surgical removal of half of the brain). Children with CFE who undergo cortical resections or hemispherectomies demonstrate an inflammatory histopathology consisting of perivascular lymphocytic cuffing, gliosis, neuronal loss, microglial nodules and later laminar necrosis and spongy degeneration. Rituximab is a genetically engineered, chimeric; murine/human monoclonal antibody directed against the CD20 antigen found on the surface of normal and malignant pre-B and mature B cells. It was approved by the FDA in 1997 for the treatment of relapsed or refractory low grade or ...
As part of the reseach group of Hans Lassmann my main research focus is the pathogenesis of inflammatory diseases of the nervous system. In this large area of research my special interest is the role of cytotoxic T lymphocytes. Cytotoxic T cell mediated tissue damage in the nervous system is studied in various human inflammatory diseases. One of these diseases studied is Rasmussen encephalitis, a epileptic disorder of unknown etiology mostly found in children. These pathological studies of Rasmussen encephalitis are performed in close cooperation with Dr. Christian Bien from the department of epileptology in Bonn. Cytotoxic T cell mediated tissue damage furthermore is studied in paraneoplastic encephalitis and virus-induced encephalitis. The study of T cell cytotoxicity in human diseases is complemented by the study of various models of autoimmune or virus induced inflammatory CNS disease. These studies are performed in long-term collaboration with the research groups of Dr. Roland Liblau ...

Our data suggest that the most important initial investigation is an MRI scan as the presence of a well-defined lesion involving noneloquent cortex such as DNET, or MTS (Cendes et al., 2000; Cukiert et al., 2002). Rasmussens encephalitis or hemimegalencephaly in a child with a clear history of stereotyped seizures may mean that no further investigation for localization of the seizure focus is required. This group of children accounts for the large majority of children who are offered epilepsy surgery. The spectrum of operations carried out is shown in Fig. 1 which is similar to those published by North American groups (Wyllie et al., 1998; Sinclair et al., 2003).. Given that our outcome data (Doring et al., 1999; Cross, 2002; Devlin et al., 2003; Mclellan et al., 2005) are similar to those reported by other units, and that there is excellent concordance (Haut et al., 2002) across epilepsy surgery programs for the decision to offer epilepsy surgery, a change in approach as suggested above is ...

The brains of people with lentiviral-associated encephalitis contain a good amount of activated and contaminated macrophages. not really in nonencephalitic macaques. At necropsy, macaques with SIVE acquired more contaminated macrophages in peripheral organs, apart from lymph nodes. T NK and cells cells with cytotoxic potential were even more loaded in brains with encephalitis; nevertheless, T-cell and NK-cell infiltration in SIVE and individual immunodeficiency pathogen encephalitis was even more modest than that observed in classical acute herpes simplex virus encephalitis. These findings support the hypothesis that inherent differences in host systemic and CNS monocyte/macrophage viral production are associated with the development of encephalitis. Prior to the era of highly active antiretroviral therapy (HAART), approximately 25% of human immunodeficiency computer virus (HIV)-infected individuals exhibited the pathological hallmarks of HIV encephalitis (HIVE) at autopsy: microglial nodules, ...
Herpes simplex virus 1 (HSV-1) encephalitis (HSE) is the most common sporadic viral encephalitis in Western countries. Over the last 15 years, human g
In this study, anti-NMDARE cases had a higher prevalence of HSV-1 IgG antibodies than age-matched controls in two separate cohorts. Antibodies to unrelated viruses (CMV and EBV-VCA) were not elevated in anti-NMDARE participants, suggesting that this finding is selective for HSV-1. HSV-1 IgG seroprevalence is greater than 60% by mid-adulthood.6 Therefore, we evaluated the association between HSV-1 infection and anti-NMDARE in children, in which reported HSV-1 IgG seroprevalence is only 26% at age 7 years.7 The rate of positive HSV-1 IgG antibodies detected in our participants with anti-NMDARE is elevated compared with this population statistic and the age-matched control group described here. In this retrospective study, with limited demographic information available, we were unable to control for race or socioeconomic status. However, HSV-1 seropositivity in anti-NMDARE participants was greater than that reported for any demographic group in this age range.7 Prospective studies may better ...
One article on anti-NMDA receptor encephalitis noted that the N-methyl-D-aspartate (AKA NMDA) receptor is, an important protein found on the surface of many nerve cells that allows them to receive signals from other nerve cells. The receptor is found throughout the brain and is involved in the formation of new memories as well as in perception and judgement. In anti-NMDA receptor encephalitis a persons immune system for some reason begins creating antibodies that cap the ends of some neurons, preventing nerve signals from crossing the synapses that normally allow the transmission of signals from neuron to neuron. When that happens, the symptoms of schizophrenia or bipolar disorder can appear ...
The clinical, neuropsychological and neuroradiological features of two patients affected by herpes simplex virus type 1 (HSV-1) encephalitis are described. An experimental study for the assessment of naming, recognition and description displayed in one patient a persistent significant impairment in naming living things. The other patient showed a failing semantic memory for the same categories, although a significant impairment emerged only for plants. In both patients, the late neuroradiological sequelae were localised mainly in the inferior and middle gyri of the left temporal lobe and in the left-side insula. In one patient, the right-side insula was also involved. The selective cerebral damage induced by HSV-1 is stressed and a correlation between the neuroradiological and neuropsychological findings is attempted. The stereotyped anatomical and neuropsychological changes lead to the belief that the virus may recognise, within the limbic system, particular cellular strains on the basis of ...
INTRODUCTION: Infectious and immune-mediated encephalitides are important but under-recognised causes of morbidity and mortality in childhood, with a 7% death rate and up to 50% morbidity after prolonged follow-up. There is a theoretical basis for ameliorating the immune response with intravenous immunoglobulin (IVIG), which is supported by empirical evidence of a beneficial response following its use in the treatment of viral and autoimmune encephalitis. In immune-mediated encephalitis, IVIG is often used after a delay (by weeks in some cases), while diagnosis is confirmed. Wider use of IVIG in infectious encephalitis and earlier use in immune-mediated encephalitis could improve outcomes for these conditions. We describe the protocol for the first ever randomised control trial of IVIG treatment for children with all-cause encephalitis. METHODS AND ANALYSIS: 308 children (6 months to 16 years) with a diagnosis of acute/subacute encephalitis will be recruited in ∼30 UK hospitals and randomised to
Encephalitis is a severe inflammatory disorder of the brain with many possible causes and a complex differential diagnosis. Advances in autoimmune encephalitis research in the past 10 years have led to the identification of new syndromes and biomarkers that have transformed the diagnostic approach to these disorders. However, existing criteria for autoimmune encephalitis are too reliant on antibody testing and response to immunotherapy, which might delay the diagnosis. We reviewed the literature and gathered the experience of a team of experts with the aims of developing a practical, syndrome-based diagnostic approach to autoimmune encephalitis and providing guidelines to navigate through the differential diagnosis. Because autoantibody test results and response to therapy are not available at disease onset, we based the initial diagnostic approach on neurological assessment and conventional tests that are accessible to most clinicians.

Individuals with encephalitis are usually hospitalized for treatment. The specific treatment is determined by the cause of the illness. Some viral infections are treatable with medication, and all patients are treated with supportive care until they recover. The patients chance of recovery depends on the specific cause of the illness and the severity of the swelling in the brain and surrounding tissues and fluids. The prognosis for viral encephalitis varies. Some cases are mild and patients recover fully. Other cases are more severe, and permanent damage or death is possible. The most severe phase of viral encephalitis may last for one to two weeks, with fever and neurologic symptoms improving gradually or suddenly. Neurologic symptoms may require many months before full recovery, and patients may require rehabilitative services. ...
Activity:. Bed rest and a 2 to 3 week recovery. You should be as active as your strength and feeling of well-being allow.. Diet:. No special diet. May require intravenous fluids. Medical personnel will monitor fluid and electrolyte levels.. Possible Complications :. Varies depending on the cause of the encephalitis. Usually a very small percentage of patients suffer permanent brain damage that impairs mental or muscle functions.. Prognosis. Mild viral encephalitis is common and may go unnoticed. Severe cases usually require hospitalization. Complications and fatalities from encephalitis are most common in infants and the elderly. People in other age groups usually recover completely. Unless the attack is severe, you can expect full recovery within 2 to 3 weeks.. Other. Nothing Specified. ...

Tour 1: Next/Previous/Start: Herpes Simplex Virus (HSV) encephalitis has its own neuroanatomy. It tends to attack a part of the brain known as the limbic system, a set of interconnected brain structures responsible for the integration of emotion, memory, and complex behavior. This disease is important to recognize because there is an effective drug treatment, acyclovir. We will see the limbic system on this tour, as shown by the lesions of a typical case of HSV encephalitis. HSV is ubiquitous, but fortunately, only 1 or 2 cases per million infected individuals develop the encephalitis of HSV each year in the US. It is the most frequently fatal of all encephalitides. In this set of images, there is a region of very bright signal on MR (and high blood flow on SPECT; use the buttons at right) in the medial temporal lobe at left (patients right). This corresponds to an area of active viral leptomeningeal and brain tissue infection. Hemorrhage can occur acutely, but is not seen in this case. You ...

We have presented a series of 13 consecutive infants with confirmed HPeV infection who were prospectively identified with suspected encephalitis through the ACE study, including 12-month neurodevelopmental follow-up by using a well-validated screening tool. HPeV accounted for 10% of total suspected encephalitis cases identified over the surveillance period, during which a large outbreak of HPeV3 infection occurred in Eastern Australia.38 Nine infants had confirmed HPeV encephalitis. Most were girls and born preterm. Key features included generalized seizures, lethargy (decreased arousability), an absence of CSF pleocytosis, and subcortical WM changes on MRI. In addition, all HPeV encephalitis cases required intensive care support, emphasizing the severity of the disease. We have observed a high proportion with neurodevelopmental sequelae at 12 months follow-up. We acknowledge that we cannot draw definitive genotype-specific conclusions because HPeV genotyping was not performed on cases outside ...
Encephalitis is an acute clinical syndrome of the central nervous system (CNS), often associated with fatal outcome or permanent damage, including cognitive and behavioural impairment, affective disorders and epileptic seizures. Infection of the central nervous system is considered to be a major cause of encephalitis and more than 100 different pathogens have been recognized as causative agents. However, a large proportion of cases have unknown disease etiology. We perform hierarchical cluster analysis on a multicenter England encephalitis data set with the aim of identifying sub-groups in human encephalitis. We use the simple matching similarity measure which is appropriate for binary data sets and performed variable selection using cluster heatmaps. We also use heatmaps to visually assess underlying patterns in the data, identify the main clinical and laboratory features and identify potential risk factors associated with encephalitis. Our results identified fever, personality and behavioural change,
