BACKGROUND: N-methyl-D-aspartate (NMDA) receptor encephalitis is an immune-mediated condition that has a broad spectrum of manifestations, including seizures, coma, psychosis, and focal neurological deficits. Although usually a diffuse process, unihemispheric involvement mimicking early stages of Rasmussen encephalitis can occur. Rasmussen's encephalitis is a unique syndrome characterized by progressive hemiplegia, drug-resistant focal epilepsy, cognitive decline, and hemispheric brain atrophy contralateral to the hemiplegia...

The epidemics of Chikungunya virus (CHIKV) and Zika virus (ZIKV) infections have been considered the most important epidemiological occurrences in the Americas. The clinical picture of CHIKV infection is characterized by high fever, exanthema, myalgia, headaches, and arthralgia. Besides the typical clinical picture of CHIKV, atypical manifestations of neurological complications have been reported: meningo-encephalitis, meningoencephalo-myeloradiculitis, myeloradiculitis, myelitis, myeloneuropathy, Guillain-Barré syndrome and others...

AIM: A systematic literature review of intravenous immunoglobulin (IVIG) treatment of paediatric neurological conditions was performed to summarize the evidence, provide recommendations, and suggest future research. METHOD: A MEDLINE search for articles reporting on IVIG treatment of paediatric neuroinflammatory, neurodevelopmental, and neurodegenerative conditions published before September 2015, excluding single case reports and those not in English. Owing to heterogeneous outcome measures, meta-analysis was not possible...

Tick-borne encephalitis (TBE) is a potentially lethal neuroinfection in humans, caused by TBE virus (TBEV). Currently, there are no approved therapeutic agents to treat TBE. Previously, it was suggested that application of high dose intravenous immunoglobulin (IVIG) may pose potentially successful treatment for severe cases of TBE. In this study, we determined the titers of TBEV-neutralizing antibodies in two IVIG lots originating from the same manufacturer, and tested their ability to treat a lethal TBEV-infection in a mouse model...

Anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis has been shown to be a treatable form of autoimmune encephalitis, but there remains no standardized approach to immunotherapy. We designed an anonymous survey sent to members of the Child Neurology Society to identify the current practices among child neurologists. A total of 151 pediatric neurologists responded to the survey. With these responses we were able to highlight areas of practice uniformity, including first-line treatment with intravenous immunoglobulin and intravenous methylprednisone and initiation of disease-modifying therapy with rituximab alone...

BACKGROUND: Anti-N-Methyl-D-Aspartate receptor (anti-NMDAR) encephalitis is responsive to immunotherapy and removal of tumor, but there is no consensus in the treatment of severe anti- NMDAR encephalitis with prolonged refractory status epilepticus (SE). CASE REPORT: A 17-year-old girl presented as acute psychosis, refractory seizures, hyperkinesia, autonomic instability, and soon progressed to a dissociative state of coma. Anti-NMDAR antibodies were positive in serum and CSF...

Since the outbreak of the enterovirus 71 (EV71) infection in Malaysia in 1997, large epidemics of EV71 have occurred in the Asia-Pacific region. Many children and infants have died from serious neurological complications during these epidemics, and EV71 infection has become a serious public health problem in these areas. EV71 infection causes hand, foot and mouth disease (HFMD) in children, and usually resolves spontaneously. However, EV71 occasionally involves the central nervous system (CNS), and induces diverse neurological complications such as brainstem encephalitis, aseptic meningitis, and acute flaccid paralysis...

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...

Identical twin brothers developed mild encephalopathy at the age of 7.0 and 9.7 years (Patient 1) and 10.7 years (Patient 2). Patient 1 had influenza A at the time of his second episode, but triggering agents were not evident at the first episode. The triggering agents in Patient 2 were unclear. The neurological features of both patients included transient facial numbness, left arm paresis, dysarthria, and gait disturbance. Diffusion-weighted images from magnetic resonance imaging showed high signal levels at the splenium of corpus callosum and in the bilateral cerebral deep white matter...

A 40-year-old man presented with a series of generalized tonic-clonic seizures after febrile illness. He developed status epilepticus and required mechanical ventilation with anesthetics. Steroid pulse, intravenous immunoglobulin, and immunoadsorption therapy were administrated, and the status epilepticus improved; however, drug-resistant seizures remained. Despite the use of several antiepileptic drugs, seizures frequently occurred. Additional administration of potassium bromide resulted in significant suppression of seizures...

Most non-immune individuals exposed to the highly contagious measles virus will develop measles. Complications, such as encephalitis and bacterial infections due to measles virus-induced immunomodulation, account for an acute mortality rate of approximately 0.1% (1). It has been calculated that measles-related immunomodulation may last for several years and may contribute to child mortality on a larger scale than acute measles-related mortality (2). Since humans provide the only host for the virus, and an efficient vaccine is available, it is possible to eliminate measles...

To date, only 1 case of BK polyomavirus (BKPyV) encephalitis combined with transplant-associated thrombotic microangiopathy has been reported in a hematopoietic stem cell transplantation (HCT) recipient. We report the case of a HCT recipient who developed thrombotic microangiopathy and subsequent BKPyV encephalitis. She died despite treatment with cidofovir, ciprofloxacin, and intravenous immunoglobulin without improvement in mental status. Early suspicion of BKPyV encephalitis in a HCT recipient presenting with altered mentality and hemorrhagic cystitis is important...

Five consecutive cases of anti-NMDA-receptor encephalitis that we encountered were marked by a rapidly fluctuating level of consciousness associated with psychotic and delirious mental states. Opisthotonus, catatonia, and rhythmic and non-rhythmic involuntary movements of the mouth and jaw were also characteristic features of these particular cases. Serious and potentially fatal problems included epilepsia partialis continua, partial and generalized seizures, and respiratory depression, resembling the symptoms of encephalitis lethargica...

INTRODUCTION: Enterovirus may result in a devastating chronic encephalitis in immunocompromised patients, particularly in patients with X-linked agammaglobulinemia. Prognosis for patients with chronic enterovirus encephalitis is poor, almost invariably resulting in mortality without specific treatment. There are currently no approved antiviral agents for enterovirus, but the antidepressant drug fluoxetine has been identified through library-based compound screening as a potential anti-enteroviral agent in vitro...

Japanese encephalitis virus (JEV), West Nile virus (WNV), and dengue virus (DenV) are causal agents of Japanese encephalitis, West Nile fever, and dengue fever, respectively. JEV is considered to be indigenized and widespread in Japan, whereas WNV and DenV are not indigenized in Japan. Globulin products seem to reflect the status of the donor population according to antivirus neutralization activity. However, the anti-JEV, -WNV, and -DenV neutralization activities of globulin products derived from donors in Japan have not been clarified...
