RESUMO
OBJECTIVES: To characterize the clinical features and to identify the predictors of recurrence of histiocytic necrotizing lymphadenitis (HNL) in Chinese children. STUDY DESIGN: This study retrospectively analyzed the clinical characteristics, laboratory and pathological findings, and recurrence status of children diagnosed with HNL at a single center in China from January 2018 to May 2023. Logistic regression analysis was employed to identify predictors of HNL recurrence. RESULTS: 181 Chinese children with histopathologically confirmed HNL were enrolled (121 males and 60 females). The mean age was 9.3 ± 2.9 years. The most prominent clinical features were fever (98.9%) and cervical lymphadenopathy (98.3%). Aseptic meningitis was the most frequent complication (38.5%), while hemophagocytic lymphohistiocytosis and autoimmune disease were rare (1.7% and 1.2%, respectively). Recurrence occurred in 12.7% of patients. Erythrocyte sedimentation rate (> 30 mm/h) was the significant predictors of HNL recurrence, with odds ratios of 6.107, respectively. CONCLUSION: Our study demonstrates that fever and cervical lymphadenopathy are the most frequent clinical manifestations of HNL in Chinese children, which often coexist with aseptic meningitis. HNL patients with risk factors require follow-up for recurrence.

The aetiology of chronic aseptic meningitis is difficult to establish. Candida meningitis in particular is often diagnosed late, as cerebrospinal fluid (CSF) work-up and imaging findings are nonspecific. A 35-year-old patient with chronic aseptic meningitis, for which repeated microbiological testing of CSF was unrevealing, was finally diagnosed with Candida albicans (C. albicans) meningitis with cauda equina involvement using metagenomic next-generation sequencing (mNGS). This report highlights the diagnostic challenges and the difficulties of treating shunt-associated fungal meningitis.

The constellation of fevers accompanied by headache and vomiting is a red flag for clinicians that appropriately triggers evaluation for meningitis and other life-threatening diagnoses. When symptoms persist even after these conditions are ruled out, patient care becomes more challenging. We present the case of a 6-year-old male with a history of autism spectrum disorder who presented with 6 months of headaches and associated vomiting and intermittent fevers with negative infectious workup despite cerebrospinal fluid pleocytosis. Serial neuroimaging and laboratory evaluation ultimately led to a diagnosis of myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) presenting as aseptic meningitis. The clinical and radiographic findings of MOGAD are widely variable and overlap with several other inflammatory conditions, which makes diagnosis challenging. This case highlights the importance of recognizing this rare MOGAD presentation as an infectious meningitis mimic.

An acute aseptic meningitis has been occasionally observed on intravenous polyclonal human immunoglobulin therapy. Since case reports cannot be employed to draw inferences about the relationships between immunoglobulin therapy and meningitis, we conducted a systematic review and meta-analysis of the literature. Eligible were cases, case series, and pharmacovigilance studies. We found 71 individually documented cases (36 individuals ≤ 18 years of age) of meningitis. Ninety percent of cases presented ≤ 3 days after initiating immunoglobulin therapy and recovered within ≤ 7 days (with a shorter disease duration in children: ≤ 3 days in 29 (94%) cases). In 22 (31%) instances, the authors noted a link between the onset of meningitis and a rapid intravenous infusion of immunoglobulins. Cerebrospinal fluid analysis revealed a predominantly neutrophilic (N = 46, 66%) pleocytosis. Recurrences after re-exposure were observed in eight (N = 11%) patients. Eight case series addressed the prevalence of meningitis in 4089 patients treated with immunoglobulins. A pooled prevalence of 0.6% was noted. Finally, pharmacovigilance data revealed that meningitis temporally associated with intravenous immunoglobulin therapy occurred with at least five different products. In conclusion, intravenous immunoglobulin may cause an acute aseptic meningitis. The clinical features remit rapidly after discontinuing the medication.

Meningitis, though commonly caused by various infectious agents, may also have non-infectious aetiologies. The clinical presentation, however may be identical to infectious meningitis. We present a case of a female in her 50s who presented with fever, headache, vomiting and neck rigidity. She had features of inflammatory polyarthritis, cold sensitivity, puffy digits, alopecia and easy fatigability. No evidence of infection was found, and serological features consistent with mixed connective tissue disease (MCTD) were revealed, which led to the diagnosis of MCTD-related aseptic meningitis.

Drug-induced aseptic meningitis (DIAM) or chemical meningitis following spinal anaesthesia has rarely been reported. DIAM is caused by meningeal inflammation due to intrathecally administered drugs or secondary to systemic immunological hypersensitivity. We hereby present a case of a young adult with aseptic meningitis following neuraxial anaesthesia possibly provoked by bupivacaine. The initial cerebrospinal fluid (CSF) picture revealed neutrophilic pleocytosis and normal glycorrhachia. CSF culture was negative. The patient was put on invasive mechanical ventilation and started on intravenous antibiotics. There was a rapid improvement in clinical condition without any residual neurological deficit within the next few days. Aseptic meningitis following neuraxial anaesthesia can be prevented by strict aseptic protocols and careful inspection of visible impurities while administering the intrathecal drug. Detailed history taking, clinical examination, and focused investigations can distinguish between bacterial and chemical meningitis. Appropriate diagnosis of this entity may guide the treatment regimen, reducing hospital stay and cost.

BACKGROUND: This case report describes a rare instance of drug-induced aseptic meningitis after an interlaminar lumbar epidural steroid injection. CASE PRESENTATION: A 74 year-old female patient presented to the ED post-procedure day three after an L4-L5 interlaminar lumbar epidural steroid injection with fever, nausea, and vomiting. The patient had previously undergone numerous lumbar epidurals without complications and used identical medications, which included 1% lidocaine, iohexol contrast, methylprednisolone (Depo-medrol), and normal saline. Pertinent labs included a WBC of 15,000 cells/µL. Lumbar MRI revealed L4-S1 aseptic arachnoiditis. Two bone scans with Gallium and T-99 confirmed no infectious process. The patient then had a second admission months later with similar presenting symptoms and hospital course after repeating the lumbar epidural steroid injection. Lumbar MRI and CSF studies confirmed aseptic meningitis. CONCLUSION: This patient's repeated admissions from aseptic meningitis were likely caused by irritation of the meningeal layers from a medication used during the procedure.

Aseptic meningitis represents a diagnostic challenge for the clinician. Cytological and chemical parameters are key in the differential diagnosis. Hypoglycorrhachia is a strong predictor of a bacterial origin for aseptic meningitis. We report a 44-year-old male with a history of recurrent febrile headaches admitted with fever and delirium. The initial cerebrospinal fluid (CSF) analysis showed low glucose levels. Magnetic resonance imaging did not show abnormalities. The patient was discharged but was admitted again three weeks later with fever, headache and a stiff neck. The CSF was inflammatory with low glucose levels. Serology for brucellosis was positive. The patient was treated with ceftriaxone and rifampicin with a good clinical response.

La enfermedad de Behçet (EB) es un trastorno de vasculitis sistémica poco frecuente, de etiología desconocida, que se caracteriza por la presencia de aftas bucales, úlceras genitales y uveítis recurrentes. Afecta los sistemas nerviosos central y periférico; raramente se produce durante la niñez. La meningitis aséptica aguda aislada es muy poco frecuente. En este artículo, se describe el caso de una paciente de 14 años con diagnóstico de enfermedad de Behçet con afectación neurológica (neuro-Behçet). La paciente tenía cefalea aguda, diplopia, papiledema e irritación meníngea. Tenía antecedentes de úlceras bucales recurrentes. Las imágenes por resonancia magnética de cerebro revelaron paquimeningitis. Los hallazgos en el líquido cefalorraquídeo fueron pleocitosis y aumento de la presión. Pese al tratamiento médico, sus síntomas no se resolvieron. No se detectó uveítis y la prueba de patergia fue negativa. El alelo HLA-B51 fue positivo. Se consideró que los hallazgos apuntaban a la poco frecuente enfermedad de Behçet con afectación neurológica. La paciente mejoró drásticamente luego del tratamiento con corticoesteroides. En el diagnóstico diferencial de meningitis, se debe considerar la EB, a menos que se demuestre la presencia de un agente infeccioso. Hasta donde sabemos, anteriormente no se había descrito un caso de paquimeningitis con neuro-Behçet en la población pediátrica.
Behçet's disease (BD) is a rare systemic vasculitis disorder of unknown etiology characterized by recurrent oral and genital apthae and uveitis. It involves the central or peripheral nervous system; occurs rarely during childhood. Isolated acute aseptic meningitis is extremely uncommon. We report here a case of Neuro-Behçet disease (NBD) diagnosed in a 14-year-old girl. The patient presented acute headache, diplopia, papilla edema, and meningeal irritation. She had a history of recurrent oral ulcers. Brain magnetic resonance imaging revealed pachymeningitis. Pleocytosis and pressure increase were the cerebrospinal fluid findings. Although medical therapy, her complaints were not resolved. Uveitis was not detected, pathergy test was negative. HLA-B51 allele was positive. The findings were considered to unusual NBD. The patient improved dramatically after steroid therapy. BD should be considered in differential diagnosis of meningitis unless an infectious agent is demonstrated. To our knowledge, a case of pachymeningitis with NBD, was not described in children.

ABSTRACT Objective: To report a case of a male adolescent with the diagnosis of ibuprofen-induced meningitis. We discuss themain causes of drug-induced aseptic meningitis (DIAM) and highlight the importance of early recognition of DIAM, sothat the offending drug can be withdrawn, and recurrences prevented. Only few DIAM cases have been reported in pediatric age. Case description: A healthy 15-year-old boy presented to the emergency department with headache, nausea, dizziness, fever, conjunctival hyperemia and blurred vision 30 minutes after ibuprofen-intake. During his stay, he developed emesis and neck stiffness. Cerebrospinal fluid analysis excluded infectious causes, and DIAM was considered. He totally recovered after drug withdrawal. Comments: DIAM is a rare entity, that should be considered in the differential diagnosis of an aseptic meningitis. The major causative agents are nonsteroidal anti-inflammatory drugs, particularly ibuprofen. Suspicion is made by the chronologic link between drug intake and the beginning of symptoms, but infectious causes should always be ruled out.
RESUMO Objetivo: Descreve-se o caso de um adolescente do sexo masculino com diagnóstico de meningite asséptica por ibuprofeno. Discutem-se as causas de meningite asséptica induzida por medicamentos (MAIM) e a importância do reconhecimento precoce dessa situação, para que a medicação envolvida seja suspensa e as recorrências prevenidas. Poucos casos foram descritos em idade pediátrica. Descrição do caso: Adolescente de 15 anos, gênero masculino, saudável, procurou o serviço de urgência por cefaleia, náuseas, tonturas, febre, hiperemia conjuntival e visão desfocada 30 minutos após o uso de ibuprofeno. Durante a internação, iniciou vômitos e rigidez na nuca. A análise do líquido cefalorraquidiano excluiu causas infeciosas, e considerou-se como diagnóstico mais provável a MAIM. A recuperação foi total após a suspensão do medicamento. Comentários: A MAIM é rara, mas deve ser considerada no diagnóstico diferencial de meningite asséptica. A principal causa são os anti-inflamatórios não esteroides, principalmente o ibuprofeno. A suspeita clínica é evocada pela relação temporal entre o uso do medicamento e o início dos sintomas, mas as causas infeciosas devem ser sempre excluídas.

A meningite recorrente linfocítica benigna ou meningite de Mollaret, inicialmente descrita pelo neurologista francês Pierre Mollaret em 1944, é uma condição relativamente rara, benigna mas incapacitante durante os seus períodos de agudização. Trata-se de quadro inï¬amatório meníngeo recorrente devido a reativação de infecção pelo herpes simples vírus, particularmente o herpesvirus do tipo 2 (HSV-2). Pode ser reconhecida a partir do seu quadro clínico de meningismo agudo, perfil liquórico linfocítico e identificação do genoma viral por PCR no líquor. Aciclovir e seus derivados podem ser utilizado no seu tratamento ou na sua profilaxia. Sua identificação é importante no sentido de se excluir outras causas de quadros meníngeos recorrentes.
Benign recurrent lymphocytic meningitis or Mollaret's meningitis (MM) was frst described by the French neurologist Pierre Mollaret in 1944. MM is a relatively rare, benign but disabling condition. MM is a recurrent meningeal inï¬ammatory illness due to reactivation of herpes simplex virus infection, particularly herpesvirus type 2 (HSV-2). It can be recognized from its clinical picture of acute meningism, lymphocytic CSF profle and by the identifcation of the viral genome in the CSF by PCR. Acyclovir and its derivatives may be used for its treatment or prophylaxis. The identifcation of MM is important in order to exclude other causes of recurrent meningeal conditions.

Aproximadamente 90% de las meningitis asépticas son causadas por enterovirus (EV), miembro de la familia de los picornavirus. Los EV son ubicuos, se diseminan por vía fecal-oral y contacto directo, responsables de brotes o casos esporádicos con importante morbilidad. El diagnóstico se basa en la presentación clínica, imágenes, estudio citoquímico del líquido cefalorraquídeo (LCR) y la Reacción en Cadena de la Polimerasa (PCR), gold estándard que reemplaza al aislamiento viral y la serología. El objetivo de este estudio descriptivo de corte transversal fue determinar la presencia de EV por RT-PCR en el LCR de pacientes con sospecha clínica de meningitis aséptica, internados en servicios públicos y privados de Asunción y departamento Central del Paraguay de noviembre de 2007 a noviembre de 2014. El material genético fue extraído mediante el mini kit ADN y ARN Qiagen® que fue sometido a RT-PCR. Se incluyeron LCR de 203 pacientes, 124 (61%) niños (4 días-15 años) y 79 (39%) adultos (16-81 años). Setenta y siete (38%) provenían de servicios públicos y 126 (62%) de privados; 115 (57%) fueron varones. Se detectó RNA de EV en 166 (82%) pacientes, 90 niños y 76 adultos, y mayor número de casos entre los meses de octubre a abril. Este es el primer trabajo en el país y muestra una importante participación del EV en pacientes por infecciones del SNC compatibles con meningitis asépticas de etiología viral. La sospecha clínica fue mayor en niños, sin embargo la proporción de resultados positivos fue mayor en adultos. Se observó mayor circulación en los meses cálidos(AU)

Mycoplasma pneumoniae (Mp) es el agente causal de un 30% de las manifestaciones respiratorias de la población general. La neumonía ocupa el primer lugar dentro de este grupo. Las manifestaciones neurológicas representan las formas más frecuentes de presentación clínica extrapulmonar (40%). Las encefalitis y meningoencefalitis son las formas más habituales de sintomatología neurológica asociada a infección por Mp. La presentación de más de una variante clínica en un mismo paciente asociada a primoinfección por Mp es posible. El diagnóstico serológico plantea, habitualmente, controversias en su interpretación. A partir del caso de una niña de 7 años con inyección conjuntival, adenopatía cervical, rash descamativo y fotofobia con "pseudoedema de papila bilateral", que desarrolla durante su evolución parálisis facial periférica y meningitis aséptica, se analizarán las controversias que se plantean en relación con la interpretación diagnóstica asociada al compromiso neurológico por Mp.
Mycoplasma pneumoniae (Mp) is responsible for 30% of the respiratory manifestations of the general population. Pneumonia occupies the first place within this group. Among the extra-respiratory forms (40%), the neurological ones are the most frequent. Meningoencephalitis and aseptic meningitis are the most common. The presentation of more than one clinical variant in the same patient associated with primoinfection by Mp is possible. In relation to the serological diagnosis, controversies in interpretation sometimes occur. This is a 7-year-old girl with conjunctival injection, cervical adenopathy, photophobia with bilateral papilla pseudoedema, and scaly rash that develops peripheral facial paralysis and aseptic meningitis. We will discuss diagnostic controversies.

RESUMO Objetivo: Avaliar o Escore para Meningite Bacteriana (EMB) isolado e associado ao valor do lactato no líquor para diferenciar meningite bacteriana (MB) e meningite asséptica (MA). Métodos: Foram selecionadas crianças com meningite atendidas em hospital terciário privado entre janeiro de 2011 e dezembro de 2014. Os dados foram obtidos na admissão. Utilizou-se o EMB com: coloração de Gram no líquor (2 pontos); neutrófilos no líquor ≥1.000 células/mm3 (1 ponto); proteína no líquor ≥80 mg/dL (1 ponto); neutrófilos no sangue periférico ≥10.000 células/mm3 (1 ponto); e convulsão durante/antes da chegada (1 ponto). Analisou-se também o lactato no líquor (elevado: ≥30 mg/dL). Avaliaram-se sensibilidade, especificidade e valor preditivo negativo de diversos valores de corte do EMB e do EMB associado ao lactato elevado para prever MB. Resultados: Dos 439 pacientes elegíveis, 94 não tinham todos os dados necessários para o escore, sendo 345 pacientes selecionados: 7 no grupo de MB e 338 no de MA. Como preditivos de MB, o EMB ≥1 mostrou sensibilidade de 100% (intervalo de confiança de 95% - IC95% 47,3-100), especificidade de 64,2% (58,8-100) e valor preditivo negativo de 100% (97,5-100), enquanto o EMB ≥2 ou EMB ≥1 associado a lactato liquórico ≥30 mg/dL mostrou sensibilidade de 100% (47,3-100), especificidade de 98,5% (96,6-99,5) e valor preditivo negativo de 100% (98,3-100). Conclusões: O EMB com 2 pontos associado à dosagem de lactato no líquor manteve a sensibilidade e o valor preditivo negativo, ao passo que aumentou a especificidade para identificar meningites bacterianas em relação à utilização do EMB com 1 ponto.
ABSTRACT Objective: To evaluate Bacterial Meningitis Score (BMS) on its own and in association with Cerebrospinal Fluid (CSF) lactate dosage in order to distinguish bacterial from aseptic meningitis. Methods: Children diagnosed with meningitis at a tertiary hospital between January/2011 and December/2014 were selected. All data were obtained upon admission. BMS was applied and included: CSF Gram staining (2 points); CSF neutrophil count ≥1,000 cells/mm3 (1 point); CSF protein ≥80 mg/dL (1 point); peripheral blood neutrophil count ≥10,000 cells/mm3 (1 point) and seizures upon/before arrival (1 point). Cutoff value for CSF lactate was ≥30 mg/dL. Sensitivity, specificity and negative predictive value of several BMS cutoffs and BMS associated with high CSF lactate were evaluated for prediction of bacterial meningitis. Results: Among 439 eligible patients, 94 did not have all data available to complete the score, and 345 patients were included: 7 in bacterial meningitis group and 338 in aseptic meningitis group. As predictive factors of bacterial meningitis, BMS ≥1 had 100% sensitivity (95%CI 47.3-100), 64.2% specificity (58.8-100) and 100% negative predictive value (97.5-100); BMS ≥2 or BMS ≥1 associated with high CSF lactate also showed 100% sensitivity (47.3-100); but 98.5% specificity (96.6-99.5) and 100% negative predictive value (98.3-100). Conclusions: 2 point BMS in association with CSF lactate dosage had the same sensitivity and negative predictive value, with increased specificity for diagnosis of bacterial meningitis when compared with 1-point BMS.

ABSTRACT Objective To measure the role of enterovirus detection in cerebrospinal fluid compared with the Bacterial Meningitis Score in children with meningitis. Methods A retrospective cohort based on analysis of medical records of pediatric patients diagnosed as meningitis, seen at a private and tertiary hospital in São Paulo, Brazil, between 2011 and 2014. Excluded were patients with critical illness, purpura, ventricular shunt or recent neurosurgery, immunosuppression, concomitant bacterial infection requiring parenteral antibiotic therapy, and those who received antibiotics 72 hours before lumbar puncture. Results The study included 503 patients. Sixty-four patients were excluded and 94 were not submitted to all tests for analysis. Of the remaining 345 patients, 7 were in the Bacterial Meningitis Group and 338 in the Aseptic Meningitis Group. There was no statistical difference between the groups. In the Bacterial Meningitis Score analysis, of the 338 patients with possible aseptic meningitis (negative cultures), 121 of them had one or more points in the Bacterial Meningitis Score, with sensitivity of 100%, specificity of 64.2%, and negative predictive value of 100%. Of the 121 patients with positive Bacterial Meningitis Score, 71% (86 patients) had a positive enterovirus detection in cerebrospinal fluid. Conclusion Enterovirus detection in cerebrospinal fluid was effective to differentiate bacterial from viral meningitis. When the test was analyzed together with the Bacterial Meningitis Score, specificity was higher when compared to Bacterial Meningitis Score alone.
RESUMO Objetivo Avaliar o papel da pesquisa de enterovírus no líquido cefalorraquidiano em comparação com o Escore de Meningite Bacteriana em crianças com meningite. Métodos Coorte retrospectiva, realizada pela análise de prontuários, incluindo pacientes pediátricos, com diagnóstico de meningite e atendidos em um hospital privado e terciário, localizado em São Paulo, entre 2011 e 2014. Foram excluídos os pacientes com doença crítica, púrpura, derivação ventricular ou neurocirurgia recente, imunossupressão, outra infecção bacteriana concomitante que necessitasse de antibioticoterapia parenteral e aqueles que receberam antibiótico 72 horas antes da punção lombar. Resultados Foram incluídos no estudo 503 pacientes. Destes, 64 foram excluídos e 94 não realizaram todos os exames para análise. Dos 345 pacientes restantes, 7 ficaram no Grupo de Meningite Bacteriana e 338 no Grupo de Meningite Asséptica. Não houve diferença estatística entre os grupos. Na análise do Escore de Meningite Bacteriana, dos 338 pacientes com possível meningite asséptica (culturas negativas), 121 deles tiveram um ou mais pontos para o Escore de Meningite Bacteriana, com valor de sensibilidade de 100%, especificidade de 64,2% e valor preditivo negativo de 100%. Dos 121 pacientes com Escore de Meningite Bacteriana positivo, 71% (86 pacientes) tiveram a pesquisa de enterovírus positiva no líquido cefalorraquidiano. Conclusão A pesquisa de enterovírus no líquido cefalorraquidiano mostrou-se eficaz em diferenciar a meningite bacteriana da viral. Analisada junto com o Escore de Meningite Bacteriana, a especificidade foi maior em comparação ao Escore de Meningite Bacteriana isolado.

Meningitis is the leading infectious syndrome that affects the central nervous system, and most cases are caused by viral infections, mainly enterovirus. The clinical diagnosis for meningitis etiology still presents major challenges. The analysis of polymerase chain reaction (PCR), white blood cells, red blood cells, glucose, protein, and lactate in the cerebrospinal fluid (CSF) provides the first clues to the diagnosis. However, the reference values of some parameters can suffer changesOBJECTIVE: Analyze the laboratory parameters of CSF in patients with enterovirus meningitis, and then, theirrelationship by age groupMETHODS: A descriptive study was conducted based on data from a CSF reference service, located in São Paulo, Brazil, on 202 individuals who had enterovirus meningitis.

The Meningitis-Retention Syndrome associates aseptic meningitis and neurogenic bladder, with a vesical dysfunction that outlasts meningitis widely. Urodynamic assessment shows a detrusor palsy with normal function of the external sphincter. We report a 24-year-old male admitted for headache, fever, myalgias and acute urinary retention, which was diagnosed as a urinary tract infection. Worsening of symptoms and slight meningeal signs prompted for a lumbar puncture that yielded a cerebrospinal fluid with 94 lymphocytes, in which etiological evaluation was inconclusive. Meningeal syndrome and myalgia subsided by the fifth day, while urinary retention persisted. A magnetic resonance imaging of the brain and spinal cord done at the fifth day, showed high intensity signals in basal ganglia and central spinal cord, not altered by contrast. These images disappeared in the imaging control performed two months later. Bladder dysfunction lasted at least until the second month of follow up.

JUSTIFICATIVA E OBJETIVOS: As meningites assépticas (MA) representam a grande maioria das meningites presentes em nosso meio. Os principais causadores dessa doença são os enterovírus. O quadro clínico caracteriza-se por cefaleia, fotofobia, sinais de irritação meníngea, náuseas, vômitos e febre. A grande dificuldade diagnóstica é que estes mesmos sintomas são encontrados nos quadros de meningites bacterianas, mais graves, demandando condutas mais agressivas. O objetivo deste estudo foi rever o assunto, destacando o manuseio dos casos suspeitos bem como suas etiologias e fisiopatologias. CONTEÚDO: Conceitos de MA, suas etiologias virais e não virais, incluindo àquelas causadas pela utilização de medicamentos. CONCLUSÃO: Devido às sobreposições sintomatológicas, introduziu-se empiricamente a antibioticoterapia intra-hospitalar no momento da suspeita de infecção meníngea, observando a evolução clínico-laboratorial do paciente.
BACKGROUND AND OBJECTIVES: The aseptic meningitis (AM) representing the vast majority of meningitis in our society. The main cause of this disease is the enteroviruses. The clinical picture is characterized by headache, photophobia, and signs of meningeal irritation, nausea, vomiting and fever. The diagnostic difficulty is that these same symptoms are found in the tables of bacterial meningitis, the most serious, demanding more aggressive treatment. This article aims to review the issue, emphasizing the management of suspected cases as well as its etiology and pathophysiology. CONTENTS: Address the concept of AM, its viral and nonviral etiologies, including those caused by medication use. CONCLUSION: Due to the overlap of the symptoms, we introduced an empirical intrahospital antibiotic treatment at the moment we suspect meningeal infection, observing the evolution of clinical and laboratory signs.

Cytokines are molecules that act as mediators of immune response; cerebral spinal fluid (CSF) IL-6 is found in all meningeal inflammatory diseases, but IL-8 is associated with acute bacterial meningitis (ABM). A case control study was done to ascertain the discriminatory power of these cytokines in differentiating ABM from aseptic meningitis (AM); IL-6 and IL-8 CSF concentrations were tested through ELISA in samples collected from patients who underwent investigation for meningitis. Sixty patients, 18 with AM, nine with bacteriologic confirmed ABM and 33 controls, assisted in 2005 (MA and controls) and 2007 (ABM) were included. Differently from controls, IL-6 concentrations were increased both in MA and ABM patients (p < 0.05). CSF IL-8 levels were higher in ABM than in AM and controls (p < 0.05). Discriminatory power in ABM as assessed by the area under receiver operator (ROC) curve was 0.951 for IL-8, using a cut-off of 1.685 ng/dL (100 percent of sensitivity and 94 percent of specificity). The CSF concentration of both IL-6 and IL-8 are increased in the presence of meningeal inflammation, IL-8 could be an important tool to differentiate ABM from AM.
