RESUMO
OBJECTIVE: Patients with X linked agammaglobulinemia are susceptible to enterovirus (EV) infections. Similarly, severe EV infections have been described in patients with impaired B-cell response following treatment with anti-CD20 monoclonal antibodies (mAbs), mostly in those treated for haematological malignancies. We aimed to describe severe EV infections in patients receiving anti-CD20 mAbs for immune-mediated inflammatory diseases (IMIDs). METHODS: Patients were included following a screening of data collected through the routine surveillance of EV infections coordinated by the National Reference Center and a review of the literature. Additionally, neutralising antibodies were assessed in a patient with chronic EV-A71 meningoencephalitis. RESULTS: Nine original and 17 previously published cases were retrieved. Meningoencephalitis (n=21/26, 81%) associated with EV-positive cerebrospinal fluid (n=20/22, 91%) was the most common manifestation. The mortality rate was high (27%). EV was the only causal agents in all reported cases. Patients received multiple anti-CD20 mAbs infusions (median 8 (5-10)), resulting in complete B-cell depletion and moderate hypogammaglobulinemia (median 4.9 g/L (4.3-6.7)), and had limited concomitant immunosuppressive treatments. Finally, in a patient with EV-A71 meningoencephalitis, a lack of B-cell response to EV was shown. CONCLUSION: EV infection should be evoked in patients with IMIDs presenting with atypical organ involvement, especially meningoencephalitis. Anti-CD20 mAbs may lead to impaired B-cell response against EV, although an underlying primary immunodeficiency should systematically be discussed.

BACKGROUND: Meningoencephalitis of unknown origin is a common cause of severe neurological disease in dogs. The term covers a heterogeneous group of noninfectious inflammatory diseases, with immune dysregulation widely accepted as the underlying disease mechanism. Current treatment consists of immunosuppression, with corticosteroids being the mainstay of virtually all treatment regimens. However, side effects of corticosteroids can be severe, and might be the cause of death in some patients. This retrospective, multi-centric study aimed at describing a population of Scandinavian dogs with meningoencephalitis of unknown origin in regards to reported side effects and cause of death, and to highlight possible differences in survival, when comparing corticosteroid monotherapy with other treatment regimens. RESULTS: Within the 5-year study period, 63 dogs were included. Of these, 35 (49.3%) died or were euthanized during the study period. Median survival time from time of diagnosis based on Kaplan-Meier curves for the overall population was 714 days (equivalent to around 25 months, range 0-1678 days). There was no statistically significant difference (P = 0.31) in survival between dogs treated with corticosteroid monotherapy (n = 26, median survival time 716 days, equivalent to around 25 months, range 5-911 days), dogs receiving a combination of corticosteroids and ciclosporin (n = 15, median survival time 916 days, equivalent to around 31 months, range 35-1678 days), and dogs receiving corticosteroids combined with either cytosine arabinoside, leflunomide, or a combination of 2 or more add-on drugs (n = 13, median survival time 1186 days, equivalent to around 40 months, range 121-1640 days). Side effects were registered for 47/63 dogs. Polyphagia (n = 37/47), polyuria/polydipsia (n = 37/47), diarrhea (n = 29/47) and lethargy (n = 28/47) were most frequently reported. The most common cause for euthanasia was relapse (n = 15/35, 42.9%), followed by insufficient or lack of treatment response (n = 9, 25.7%). Side effects were the direct cause of euthanasia in 2/35 dogs (5.7%). CONCLUSIONS: A large proportion of dogs in the overall population were euthanized due to relapse, emphasizing a need for treatment regimens aimed at specifically preventing relapse for an improved long-term survival. Side effects in dogs receiving corticosteroid monotherapy were rarely a direct cause of death, but were reported for all dogs. No statistically significant difference in survival was found when corticosteroid monotherapy was compared to other treatment regimens.

Meningoencephalitis (ME) is potentially fatal and is caused by a wide array of pathogens. Diagnostic and health-care access gaps prevent accurate estimation of the pathogen-specific burden in low-resource settings. We present pathogen-specific etiologies among patients hospitalized with ME in Karachi, Pakistan. We performed a retrospective hospital database evaluation of pathogen etiology and outcomes of community-acquired infectious ME at a single tertiary care center in Karachi, Pakistan. Annual rates of hospitalization (ARH) were calculated by adjusting for missed cases and are reported per 100,000 population. From May 2017 to April 2020, 522 episodes of infectious ME were identified in 514 patients. The overall ARH from ME was 5.7/100,000 population (95% CI, 5.1-6.1). Among children younger than 5 years, the ARH was 9.8/100,000 population (95% CI, 8.1-11.8). Unknown causes of ME resulted in the greatest burden, with an ARH of 1.9/100,000 population (95% CI, 1.7-2.2). Among known causes, the greatest burden of hospitalizations resulted from tuberculous ME (0.8/100,000; 95% CI, 0.6-0.97), followed by pneumococcal and enteroviral ME (both 0.6/100,000 population; 95% CI, 0.5-0.8). The burden of ME caused by pathogens preventable through vaccination or public health measures outweighed that of ME from other causes (P = 0.0092, Fisher's exact test). We report a broad range of pathogens causing ME in southern Pakistan and show a high burden of preventable illness. Synergistic actions to improve diagnostic strategies, increase vaccinations, and introduce measures to reduce water-borne and vector-borne diseases are required to reduce the ME burden in Pakistan and prevent future outbreaks.

OBJECTIVE: Report a case of localized necrotizing meningoencephalitis as the cause of functional hearing loss after cochlear implant (CI) surgery. CASE REPORT: A 12-year-old with bilateral CI presented to our quaternary center due to severe functional hearing loss after 11 years since left ear CI surgery. CT with contrast was conducted showing a CPA tumor-like mass. Pre-operative computed tomography (CT) scans and magnetic resonance imaging (MRI) performed at the age of 1 year showed no inner ear abnormalities and in particular no evidence of a tumor in the cerebellopontine angle (CPA). CONCLUSION: Following removal of the CI and the mass, histopathological, immunohistochemical and cultural examinations revealed a necrotizing meningoencephalitis, with the CI electrode as the focus.

Many cases of aseptic meningitis or meningoencephalitis, unresponsive to antimicrobial treatments, have been reported recently in patients with established/new-onset central nervous system (CNS) inflammatory demyelinating diseases (CNSIDDs). Given the higher probability of infectious etiologies, CNSIDDs are rarely considered among the differentials in meningitis or meningoencephalitis cases. We gathered and tabulated cases of non-infectious, steroid-responsive meningitis or meningoencephalitis associated with neuromyelitis optica spectrum disorder (NMOSD) and myelin oligodendrocyte glycoprotein-associated disease (MOGAD). This conceptual review highlights the need to bolster routine infectious workups with immunological workups in cases of meningoencephalitis or meningitis where potential autoimmune etiologies can be suspected. Although differentiating CNSIDDs with meningeal involvement from infectious meningitis may not substantially affect acute treatment strategies, long-term management and follow-up of the two are entirely different. We also discuss future research directions and hypotheses on how CNSIDDs may be associated with meningitis-like presentations, e.g. overlapping glial fibrillary acidic protein astrocytopathy or autoimmune encephalitis, alterations in regulatory T-helper cells function, and undetected viral agents.

The topic of SARS-CoV-2 coronavirus infections in children is still complex and not fully understood. Acute meningoencephalitis (ME) was not considered a common presentation of COVID-19 in paediatrics, however, over time, several paediatric patients with ME associated with SARS-CoV-2 coronavirus infection have been described. The case report describes the clinical case of a newborn admitted to the Neonatal Intensive Care Unit (NICU) on 11th day of life due to severe SARS-CoV-2 coronavirus infection, who experienced multiple seizure episodes. The patient was diagnosed with ME and hydrocephalus. In the absence of clinical improvement, despite the use of standard treatment, acetazolamide (ACZ) was used, achieving complete relief of seizures and gradual regression of hydrocephalus. This means that ACZ can be considered as an add-on therapy to standard treatment in cases of ME and postinflammatory hydrocephalus in the course of COVID-19 disease.

INTRODUCCIÓN: La meningitis bacteriana aguda (MBA) y la encefalitis son infecciones graves y el retraso en el tratamiento determina mayor morbimortalidad. En 2015 la FDA. aprobó un panel de RPC múltiple, BioFire® Filmarray® meningitis-encefalitis (FA-ME), que desde el 2019 se encuentra disponible en nuestro hospital. OBJETIVOS: Estimar número de determinaciones positivas mediante FA-ME, evaluar concordancia con cultivo convencional (CC) y describir si FA-ME permitió realizar cambios en el tratamiento. MATERIAL Y MÉTODOS: Estudio retrospectivo, descriptivo, realizado durante 2019-2021 en el Hospital de Niños Pedro Elizalde. Se revisaron reportes de niños con meningitis, encefalitis y meningoencefalitis y líquido-cefalorraquídeo patológico a quienes se les realizó FA-ME. RESULTADOS: Se incluyó a 32 niños, edad promedio: 48 meses. Fueron positivas 13 determinaciones de FA-ME: siete bacterias y seis virus. En dos MBA obtuvo desarrollo mediante CC. Con FA-ME se ajustó el tratamiento en dos MBA y se acortó el tratamiento intravenoso (IV). DISCUSIÓN: Nuestro trabajo permitió conocer la etiología de cinco MBA con cultivo negativo, de las cuales dos habían recibido antimicrobianos, administrar quimioprofilaxis a contactos epidemiológicos, acortar el tratamiento IV y suministrar menos dosis de aciclovir; en concordancia con la literatura médica. CONCLUSIONES: FA-ME permitió identificar la etiología en cinco MBA que no desarrollaron en CC, ajustar tratamientos empíricos inadecuados y acortar duración del tratamiento parenteral.
BACKGROUND: Bacterial meningitis and encephalitis are life-threatening infections, a delay in its treatment is associated with high mortality. In 2015, FDA approved the Multiplex PCR FilmArray™ meningitis/encephalitis syndromic panel (FA-MEP), and it is available in our hospital since 2019. AIM: To estimate the number of positive FA-MEP, to evaluate the correlation to conventional culture (CC) results and to describe if the FA-MEP technology allowed changes in the treatment. METHODS: Retrospective analysis of children with meningitis, encephalitis and meningoencephalitis and pathological cerebrospinal fluid analysis between 2019-2021, who were subject to FA-MEP testing at the Pedro Elizalde Children's Hospital. RESULTS: 32 children, mean age: 48 months. 11 patients had positive FA-ME tests: 7 bacterial, 6 viral. 2 patients correlated with CC. Based on the FAMEP results, treatment was adjusted in 2 bacterial meningitis and the duration of intravenous treatment was shortened. DISCUSSION: Our study allowed to establish the etiology of 5 culture negative bacterial meningitis, (2 had prior antibiotics), administer chemoprophylaxis to close contacts, and to administer fewer doses of acyclovir. CONCLUSIONS: The FA-MEP allowed us to identify 5 bacterial meningitis that tested negative by CC and early adjustment of inappropriate empirical antibiotics and to shorten the duration of parenteral treatments.

Le Fort I osteotomies, although they are common procedures, carry a degree of risk of injury to the surrounding structures. Skull base fractures and cerebrospinal fluid rhinorrhoea are amongst the most serious on the list of complications. This is the first reported case of meningoencephalitis post Le Fort I osteotomy, shedding some light on its identification, causes, and management.

We herein report a 72-year-old woman with rheumatoid vasculitis who exhibited a depressed level of consciousness after receiving the first dose of the Pfizer-BioNTech mRNA BNT162b COVID-19 vaccine and was diagnosed with meningoencephalitis. Although there was no confirmatory examination, the diagnosis was based on magnetic resonance imaging (MRI) findings and etiological assessments, including microbiological and autoimmune investigations. Both intravenous steroid pulse and gammaglobulin therapies alleviated the patient's symptoms, and the MRI findings improved. Although the efficacy of COVID-19 vaccination has been widely accepted, such neurologic complications might occur in patients with rheumatoid diseases or vasculitis syndromes.

We report two patients with meningoencephalomyelitis without evidence of extra central nervous system (CNS) involvement. Brain MRI showed linear perivascular radial gadolinium enhancement patterns and spinal cord MRI showed longitudinal extensive T2-hyperintensity lesions. Pathological findings from brain biopsies were angiocentric T-cell predominant lymphoid infiltrates that lacked Epstein-Barr virus-positive atypical B cells. The patients were initially suspected to have isolated CNS-lymphomatoid granulomatosis (LYG). Thereafter, glial fibrillary acidic protein (GFAP)-immunoglobulin G were detected in their cerebrospinal fluid. This finding suggested autoimmune GFAP astrocytopathy. We speculate there is a link between isolated CNS-LYG and autoimmune GFAP astrocytopathy.

RATIONALE: Aseptic meningoencephalitis is a rare central nervous system complication of relapsing polychondritis (RP). PATIENT: We report a 61-year-old Japanese male patient with spiking fever and impaired consciousness. Neurological examination revealed meningealirritation, and cerebrospinal fluid (CSF) examination showed lymphocytic pleocytosis with elevated protein (199âmg/dL) and interleukin-6 (3810âpg/mL). Serological analysis showed high levels of anti-type II collagen antibodies, and the result of auricular biopsy was consistent with the diagnosis of RP showing cartilage degeneration surrounded by inflammatory cell infiltrations. DIAGNOSIS: A clinical diagnosis of RP was made according to the diagnostic criteria established by MacAdams et al. INTERVENTION: Steroid pulse therapy (methylprednisolone 1000âmg, consecutive 3âdays) followed by oral prednisolone (60âmg/day) resolved the patient's high fever and disturbance of consciousness. OUTCOMES: The patient rapidly improved after steroid treatments and has a normal quality of life under the maintenance dose of steroid plus methotrexate (4âmg/week). LESSONS: RP-associated meningoencephalitis is a rare complication with significant morbidity and mortality. It should be considered and differentiated in patients with RP with unexplained spiking fever and impaired consciousness. In addition, the assessment of cerebrospinal fluid interleukin-6 levels may be useful to investigate the disease activity of RP-related meningoencephalitis. Further prospective studies are required to confirm this result.

The frequency of bacterial factors causing central nervous system infections has decreased as a result of the development of our national immunization program. In this study, it is aimed to obtain the data of our local surveillance by defining the viral etiology in cases diagnosed with meningoencephalitis for 1 year. Previously healhty 186 children, who applied with findings suggesting viral meningoencephalitis to 8 different tertiary health centers between August 2018 and August 2019, in Istanbul, were included. The cerebrospinal fluid (CSF) sample was evaluated by polymerase chain reaction. The M:F ratio was 1.24 in the patient group, whose age ranged from 1 to 216 months (mean 40.2 ± 48.7). Viral factor was detected in 26.8%. Enterovirus was the most common agent (24%) and followed by Adenovirus (22%) and HHV type 6 (22%). In the rest of the samples revealed HHV type 7 (10%), EBV (6%), CMV (6%), HSV type 1 (6%), Parvovirus (4%) and VZV (2%). The most common symptoms were fever (79%) and convulsions (45.7%). Antibiotherapy and antiviral therapy was started 48.6% and 4% respectively. Mortality and sequela rate resulted 0.53% and 3.7%, respectively. This highlights the importance of monitoring trends in encephalitis in Turkey with aview to improving pathogen diagnosis for encephalitis and rapidly identifying novel emerging encephalitis-causing pathogens that demand public health action especially in national immunisation programme.

A 78-year-old woman was diagnosed with herpes zoster in the first branch of the trigeminal nerve and was treated with amenamevir. Subsequently, she was hospitalized for postherpetic neuralgia. Fever and unconsciousness were observed, and a diagnosis of varicella-zoster virus meningoencephalitis and vasculitis was made. In addition to the antithrombotic therapy, she was treated with intravenous acyclovir and steroid pulse therapy; however, her unconsciousness persisted. Amenamevir was not transferrable to the spinal fluid and resulted in an incomplete treatment of herpes zoster in the cerebral nerve region, suggesting that this case may be related to the severe course of the disease.

BACKGROUND: West Nile virus (WNV) infections have become increasingly prevalent in certain European countries, including Hungary. Although most human infections do not cause severe symptoms, in approximately 1% of cases WNV infections can lead to severe WNV neuroinvasive disease (WNND) and death. The goal of our study was to assess the neurological status changes of WNV -infected patients admitted to inpatient care and to identify potential risk factors as underlying reasons for severe neurological outcome. METHODS: We conducted a retrospective chart review of 66 WNV-infected patients from four Hungarian medical centers. Patients' neurological status at hospital admission and at two follow-up intervals (1st follow-up, within 60-90 days and 2nd follow-up, within 150-180 days, after hospital discharge) were assessed. All of the 66 patients in the initial sample had some type of neurological symptoms and 56 patients were diagnosed with WNND. The modified Rankin Scale (mRS) and the West Nile Virus Neurological Index (WNV-N Index), a scoring system designed for the purpose of this study, were used for neurological status assessment. Patients were dichotomized into two categories, "moderately severe" and "severe" based on their neurological status. Descriptive analysis for sample description, stratified analysis for calculation of odds ratio (OR) and logistic regression for continuous input variables, were performed. RESULTS: The average number of days between the onset of neurological symptoms and hospital admission (the neurological symptom interval) was 6.01 days. Complications during the hospital stay arose in almost a fifth of the patients (18.2%) and 5 patients died. Each day's increase in the neurological symptom interval significantly increased the risk for developing a severe neurological status following hospital admission (0.799-fold and 0.688-fold, based on the WNV-N Index and mRS, respectively). Patients' age, comorbidity, presence of complications and symptoms of malaise, and gait uncertainty were shown to be independent risk factors for severe neurological status. CONCLUSIONS: Timely hospital admission of patients with neurological symptoms as well as risk assessment by clinicians - possibly with an optimal assessment tool for estimating neurological status- could improve the neurological outcome of WNV-infected patients.

Burn patients with large burn surface area involvement are at increased risk of infection due to the presence of large wounds, multiple surgeries, prolonged intensive care unit admission, and immunosuppression. Pseudomonas aeruginosa is the most commonly isolated organism in this population. Even with frequent infections in the burn population, meningitis and encephalitis are rare, and ventriculitis is exceptional. We report the case of a 66-year-old woman who developed P. aeruginosa bacteremia during her hospital course, causing secondary meningoencephalitis with ventriculitis. She was admitted for partial- and full-thickness burns affecting the neck, chest, abdomen, upper medial arms, and bilateral anteromedial thighs for an estimated 20% total body surface area burn. She met sepsis criteria and broad-spectrum antimicrobial coverage was initiated. Magnetic resonance imaging of the brain, performed for altered mental status, revealed meningitis and ventriculitis. Cerebrospinal fluid analysis demonstrated findings consistent with bacterial meningitis, with cultures positive for P. aeruginosa. Serial neuroimaging with computerized tomography revealed new areas of ischemia concerning for septic emboli. In the presence of altered mental status and fever of unknown origin, workup should remain broad. Even in the presence of another source, it is important to keep an open mind for the rarer intracerebral infection as it requires different management, including urgent evaluation of antibiotic selection and dosing to ensure central nervous system penetration, and neurosurgical evaluation.
