The enteric nervous system (ENS) and a glutamate receptor (GluR), N-methyl-D-aspartate receptor (NMDAR), participate in gastric acid secretion (GAS) regulation. NMDARs are localized in different stomach cells; however, knowledge of NMDAR expression and function in the ENS is limited. In the present study, we clarified the types of stomach cells that express the NMDARs that are involved in GAS regulation. The pharmacological method of isolated stomach perfusion by Ghosh and Shild combined with direct mapping of NMDARs by fluorescence microscopy in the rat stomach was employed...

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.

OBJECTIVE: Early diagnosis of autoimmune encephalitis (AE) to not delay treatment is challenging but needed in practice. Most previous evidences of electroencephalographic (EEG) findings in AE were derived from descriptive studies. Given paucity of evidence of specific EEG findings to help with early diagnosis of AE, this study aimed to ascertain specific EEG findings and assess their predictive values in diagnosis of AE. METHODS: We included all cases with AE in our institution from January 2013 to June 2017...

Anti-N-methyl-D-aspartic acid-receptor (NMDA-R) encephalitis is a novel disease discovered within the past 10 years. It is an autoimmune disease (AD) that has been associated with other ADs, such as Graves' disease. However, association with autoimmune polyglandular syndromes (APS) has not been previously described. A 58-year-old woman presented with altered mental status and an 8-month history of weight loss, apathy and somnolence. Laboratory evaluation confirmed Graves' disease with thyrotoxicosis and type 1 diabetes mellitus...

To facilitate the diagnosis of anti-NMDAR encephalitis presenting with brain lesions in unconventional locations (BLUL) on MRI, we retrospectively analyzed forty-five Chinese patients. Eighteen (40.0%) of their MRI initially exhibited one or more BLUL. These locations predominantly included cerebral gray matter (cortex, basal ganglia and thalamus), as well as white matter and brainstem. Due to these BLUL, thirteen (72.2%) patients were originally misdiagnosed with other diseases and developed poor clinical and imaging outcomes...

A 25-year-old woman in her 37 weeks and 5 days pregnant presented with abnormal behavior and memory impairment following a high fever. Her manifestations were diagnosed as limbic encephalitis, and she delivered a baby by Cesarean section. In the operation, bilateral ovarian tumors were found and resected, though they were revealed as non-teratoma afterward. After operation, she became agitated, and started to present oral dyskinesia, intractable systemic myoclonus, central hypoventilation, and autonomic manifestations such as labile blood pressure, but her symptoms responded well to immunotherapy...

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, this review was conducted to summarise published studies regarding the use of MRI and PET in the diagnosis of anti-NMDA receptor encephalitis...

OBJECTIVE: Anti-NMDA receptor encephalitis (NMDARE) may not respond to first line immunotherapy. Biomarkers to track disease course and guide escalation of immunotherapy are needed. We describe the evolution of EEG in four patients with NMDARE requiring prolonged intensive care. METHODS: Within a database of 121 patients with immune-mediated neurological disorders, ten with NMDARE were retrospectively identified. Four patients did not respond to first line immunotherapy...

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=1.22x10-17 , 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 in a cluster of zink-finger genes...

Anti-N-methyl D-aspartate receptor (NMDAR) encephalitis is a paraneoplastic, immune-mediated encephalopathy with a known association with ovarian teratomas. We present the first case in the UK of a 7-year-old patient presenting with this condition. Having been previously fit and healthy, the patient presented with an acute onset of cognitive disturbances. The initial suspicion was that of an infective encephalopathy; however, the lumbar puncture results were negative. Electroencephalography reported diffuse background slowing, supporting a diagnosis of encephalopathy...

This report describes a rare case presenting with dystonic seizures due to anti-N-methyl-D-aspartate (NMDA) receptor encephalitis. The patient was an 18-year-old woman with repeated right-dominant dystonic seizures even under sedation. Single-photon emission computed tomography (SPECT) showed intense hyperperfusion of the caudate nuclei, putamen, globus pallidus, thalamus, and insula on the left side, suggesting encephalitis. Antibodies against NMDA receptors were detected in the sera and cerebrospinal fluids...

N -methyl-d-aspartate receptors (NMDARs) are ionotropic glutamate receptors important for synaptic plasticity, memory, and neuropsychiatric health. NMDAR hypofunction contributes to multiple disorders, including anti-NMDAR encephalitis (NMDARE), an autoimmune disease of the CNS associated with GluN1 antibody-mediated NMDAR internalization. Here we characterize the functional/pharmacological consequences of exposure to CSF from female human NMDARE patients on NMDAR function, and we characterize the effects of intervention with recently described positive allosteric modulators (PAMs) of NMDARs...

PURPOSE OF REVIEW: Neuropsychiatric manifestations are one of the fatal complications in patients with systemic lupus erythematosus (SLE). However, the diagnosis and monitoring of that aspect of SLE is still challenging, as there are no reliable biomarkers linked to central nervous system (CNS) damage. This review emphasizes potential candidate autoantibodies that appear to be associated with development of behavioral and psychiatric manifestations in SLE patients. RECENT FINDINGS: Developments in the pathogenesis in SLE, not surprising for this immune disorder, point to specific, autoantibody toxicity...

Treatments for the anti-NMDA receptor encephalitis usually include steroids, intravenous immunoglobulin, plasma exchange, plasmapheresis, rituximab, cyclophosphamide and tumor resection. We aimed to compare the efficacy of the treatments including intravenous immunoglobulin, plasma exchange, plasmapheresis, rituximab or cyclophosphamide for male anti-NMDA receptor encephalitis patients without tumor and to discuss potential biomarkers for this disease. The Fisher exact test and the contingency table analysis were used to analyze the treatment efficacy for both male and female these patients...
