Fulminant course in a patient with anti-N-methyl-D-aspartate receptor encephalitis with bilateral ovarian teratomas: A case report and literature review.

Anti-N-methyl-D-aspartate (NMDA) receptor encephalitis is an autoimmune disorder that can be controlled and reversed by immunotherapy. The presentation of NMDA receptor encephalitis varies, but NMDA receptor encephalitis is seldom reported in patients with both bilateral teratomas and preexisting brain injury.

Anti-N-methyl-D-aspartate receptor encephalitis associated with acute Toxoplasma gondii infection: A case report.

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis has been recognized as the most frequent autoimmune encephalitis in children. Several infectious agents have been implicated in anti-NMDA encephalitis.

An anti-NMDA receptor encephalitis mimicking an HIV encephalitis.

The incidence of HIV associated neurocognitive disorders (HAND) were reduced with the use of antiretroviral therapy. In case of neuropsychiatric symptoms, after elimination of all infections, auto-immune encephalitis could be evocated as a differential diagnosis. We describe a case of anti-N-Methyl-d-Aspartate receptor encephalitis in an HIV-1 infected woman.

Genetic predisposition in anti-LGI1 and anti-NMDA receptor encephalitis.

We performed a genome-wide-association study in 1,194 controls and 150 patients with anti-N-methyl-D-aspartate receptor (anti-NMDAR, n=96) or anti-leucine-rich glioma-inactivated1 (anti-LGI1, n=54) autoimmune encephalitis. Anti-LGI1 encephalitis was highly associated with 27 SNPs in the HLA-II region (leading SNP rs2858870 P=1.22x10, OR=13.66 [7.50-24.87]). Potential associations, below genome-wide significance, were found with rs72961463 close to the doublecortin-like kinase 2 gene (DCLK2) and rs62110161 i...

Magnetic resonance imaging and positron emission tomography in anti-NMDA receptor encephalitis: A systematic review.

Due to a variety of clinical manifestations anti-N-methyl-d-aspartate (NMDA) receptor encephalitis may be difficult to diagnose. Magnetic resonance imaging (MRI) may be used as a component of the workup for encephalopathy. However, the use of MRI in anti-NMDA encephalitis is complicated by wide-ranging reports regarding the frequency of normal MRI findings in this disease. Positron emission tomography (PET) is a modality of imaging that may assess functional rather than structural disturbances. Therefore, t...

18F-FDG PET/CT in Anti-NMDA Receptor Encephalitis: Typical Pattern and Follow-up.

We report the case of a 28-year-old woman presenting behavior disorders of subacute onset. She was referred in our institution for a suspicion of limbic encephalitis. F-FDG PET/CT did not show any mesiotemporal abnormality but depicted a decreased uptake of bilateral parietal and occipital lobes. This atypical pattern was compatible with an anti-N-methyl-D-aspartate receptor encephalitis that was later confirmed.

Thyroid Function and Autoimmune Indications in Patients with Anti-N-Methyl-D-Aspartate Receptor Encephalitis.

Previous studies have shown that functional abnormalities of the thyroid are associated with the pathogenesis of several neurological diseases. However, their relationship in patients with anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis remains to be defined.

Nonsteroidal anti-inflammatory drug, indomethacin improves spatial memory and NMDA receptor function in aged animals.

A redox-mediated decrease in N-methyl-D-aspartate (NMDA) receptor function contributes to psychiatric diseases and impaired cognition during aging. Inflammation provides a potential source of reactive oxygen species for inducing NMDA receptor hypofunction. The present study tested the hypothesis that the nonsteroidal anti-inflammatory drug indomethacin, which improves spatial episodic memory in aging rats, would enhance NMDA receptor function through a shift in the redox state. Male F344 young and aged rats...

Anti-NMDA receptor antibody-positive meningoencephalitis with SIADH and CNS demyelination: A case report.

After a 34-year-old female developed a headache and high fever, she was diagnosed with aseptic meningitis. On admission, neurological examinations revealed cerebellar limb ataxia, horizontal gaze paretic nystagmus, and pyramidal tract signs. Laboratory tests showed hyponatremia (129 mEq/l). Five days after admission, convulsions in the upper limbs due to the severe hyponatremia (108 mEq/l) were noted. In addition, serum antidiuretic hormone levels were markedly increased to 18.5 pg/ml. Brain MRI showe...

Neuropsychological assessment as an objective tool to monitor treatment response in anti-N-methyl-D-aspartate receptor encephalitis.

We report a 1-year follow-up of a young woman with anti-N-methyl-D-aspartate receptor encephalitis. Management of autoimmune encephalitis remains challenging as objective and clinically relevant biomarkers are sought, which allow for the monitoring of treatment response. While further investigation is required, we believe that this case highlights the importance of following a comprehensive neuropsychological profile as a clinically relevant biomarker to guide therapeutic decision-making. By relying on the ...

Plasma cell depletion with bortezomib in the treatment of refractory NMDAR-antibody encephalitis. Rational developments in neuroimmunological treatment.

To assess the therapeutic potential of bortezomib in treatment refractory NMDA receptor (NMDAR) antibody encephalitis and its potential in other immune mediated, B-cell driven neurological diseases.

NMDA Receptor Autoantibodies in Autoimmune Encephalitis Cause a Subunit-Specific Nanoscale Redistribution of NMDA Receptors.

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a severe neuropsychiatric disorder mediated by autoantibodies against the GluN1 subunit of the NMDAR. Patients' antibodies cause cross-linking and internalization of NMDAR, but the synaptic events leading to depletion of NMDAR are poorly understood. Using super-resolution microscopy, we studied the effects of the autoantibodies on the nanoscale distribution of NMDAR in cultured neurons. Our findings show that, under control conditions, NMDARs form n...

Acute encephalitis - diagnosis and management.

Encephalitis, inflammation of the brain, is most commonly caused by a viral infection (especially herpes simplex virus [HSV] type 1 in the UK) although autoimmune causes, such as N-methyl D-aspartate receptor (NMDAR) antibody encephalitis, are increasingly recognised. Most patients present with a change in consciousness level and may have fever, seizures, movement disorder or focal neurological deficits. Diagnosis hinges crucially on lumbar puncture and cerebrospinal fluid (CSF) examination, but imaging and...

Breakthrough treatment with bortezomib for a patient with anti-NMDAR encephalitis.

After its discovery, anti-N-methyl-d-aspartate receptor encephalitis is now an established neuroinflammatory disorder, for which various immune-suppressive strategies have been successfully proposed. The most commonly applied therapy includes high dose cortico-steroids, as well as plasma exchange procedures (PLEX), and subsequently either oral immunosuppressants, such as azathioprine or B-cell depletion by the anti- CD20 monoclonal antibody rituximab. However, in rare cases we are faced with patients who do...

Clinical significance of IgM and IgA class anti-NMDAR antibodies in herpes simplex encephalitis.

Herpes simplex encephalitis (HSE) is a devastating disease, often leaving patients with severe disabilities. It has been shown that IgG anti-N-methyl-d-aspartate receptor (NMDAR) antibodies appear in approximately 25% of HSE patients and could be associated with impaired recovery of cognitive performance.

A Systematic Review of the Neuropsychological Sequelae of People Diagnosed with Anti N-Methyl-D-Aspartate Receptor Encephalitis in the Acute and Chronic Phases.

A systematic review was conducted to investigate the emerging cognitive profile for people diagnosed with anti-N-methyl-d-aspartate receptor (anti-NMDAR) encephalitis.

Multistage neurorehabilitation of an adolescent with severe anti-N-methyl-D-aspartate receptor encephalitis: a case report.

We report on a 15-year-old girl with severe anti-N-methyl-D-aspartate receptor encephalitis who had initial poor prognostic factors. We delineate the unique challenges faced in the rehabilitation of our patient including sleep disruption and food aversion. After 20 months of hospitalization and intensive rehabilitation, there was a significant improvement in functional abilities and self-care skills. However, she had residual neurocognitive deficits, visual perceptual, and motor coordination difficulties th...

Coexistence of Lambert-Eaton myasthenic syndrome and autoimmune encephalitis with anti-CRMP5/CV2 and anti-GABAB receptor antibodies in small cell lung cancer: A case report.

Autoimmune encephalitis and Lambert-Eaton myasthenic syndrome are classic paraneoplastic neurological conditions common in patients with small cell lung cancer.

Development of an improved RT-qPCR Assay for detection of Japanese encephalitis virus (JEV) RNA including a systematic review and comprehensive comparison with published methods.

Japanese encephalitis virus (JEV) is a major cause of encephalitis in Asia, and the commonest cause of mosquito-borne encephalitis worldwide. Detection of JEV RNA remains challenging due to the characteristic brief and low viraemia, with 0-25% of patients positive, and the mainstay of diagnosis remains detection of anti-JEV IgM antibody.

Anti-NMDAR encephalitis as a serious adverse event probably related to yellow fever vaccination.

We present a case of a 17-year-old female with anti-NMDAR encephalitis probably associated with vaccination against yellow fever. Her symptoms occurred 27 days after vaccination against yellow fever. Anti-NMDAR encephalitis manifested as acute psychosis, memory loss and catatonia following fever with complex partial epileptic seizures. Interictal electroencephalogram showed slow-wave delta background activity with "delta brushes". The diagnosis was confirmed by NMDAR antibody positivity in serum and cerebro...

Autoimmune encephalitis associated with two antibodies.

•In patients presenting with clinical manifestations of encephalitis without clinical or laboratory signs of infection, an autoimmune etiology should be suspected.•Antibodies for various neural antigens may coexist, thus a complete and clinically-guided autoimmune panel must be done in suspected cases of autoimmune encephalitis.•Tumor resection, if applicable, combined with high dose steroids and immunotherapy are effective treatment strategies for autoimmune encephalitis with coexisting antibodies.

Beyond the limbic system: disruption and functional compensation of large-scale brain networks in patients with anti-LGI1 encephalitis.

Hippocampal inflammation in anti-LGI1 encephalitis causes memory deficits, seizures and behavioural abnormalities. Recent findings suggest that extralimbic brain areas are additionally affected and that patients also suffer from non-limbic cognitive symptoms. Moreover, up to 60% of patients show no structural MRI abnormalities in the acute disease stage. We therefore investigated whether functional connectivity analyses can identify brain network changes underlying disease-related symptoms.

EGFR gene copy number decreases during anti-EGFR antibody therapy in colorectal cancer.

Epidermal growth factor receptor (EGFR) gene copy number (GCN) increase is associated with a favourable anti-EGFR antibody treatment response in RAS wild-type metastatic colorectal cancer. However, there are limited comparative data regarding the EGFR GCN in primary colorectal cancer tumours and corresponding metastases or the effect of anti-EGFR antibody treatment on EGFR GCN in recurrent disease. Additionally, little is known about the potential EGFR GCN changes during anti-EGFR therapy in comparison to o...

Anti-N-methyl-D-aspartate receptor encephalitis relapse in the brainstem.

Fast changes of NMDA and AMPA receptor activity under acute hyperammonemia in vitro.

It was established in experiments on cell cultures of neurons and astrocytes that ammonium ions at concentrations of 4 - 8 mM cause hyperexcitation of the neuronal network, as a result of which there is a disturbance of calcium homeostasis, which can lead to the death of neurons. In the present study, we investigated the effect of toxic doses of ammonium (8 mM NHCl) on the activity of NMDA and AMPA receptors and the role of these receptors in spontaneous synchronous activity (SSA). In a control experime...
