ABSTRACT

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.

ABSTRACT

Introducción: la meningitis es un síndrome clínico que conlleva riesgos en la morbimortalidad sobre todo en edad pediátrica, la variabilidad de las manifestaciones clínicas dependientes de la edad, ha permitido el empleo de scores que permitan objetivar la toma de decisiones sobre posibilidades etiológicas y criterios terapéuticos, tal es el caso del "Score de Boyer". Objetivo: determinar la validez del Score de Boyer y la utilidad en el diagnóstico diferencial de meningitis bacteriana y no bacteriana. Material y métodos: el presente estudio es de tipo analítico, longitudinal, prospectivo, realizado en el periodo de marzo del 2014 a enero del 2015 en el Hospital del Niño Manuel Ascencio Villarroel. La muestra fue conformada por de 32 pacientes entre las edades de 1 mes a 15 años, los cuales fueron diagnosticados de meningitis por clínica, laboratorio, y por citoquímico de líquido cefalorraquídeo. Resultados: se encontró que el 25% de la población presento el diagnóstico de meningitis bacteriana confirmado con cultivo de LCR positivo. El score de Boyer en este estudio demostró una especificidad del 92% y una sensibilidad del 100% para el diagnóstico diferencial de meningitis bacteriana. Conclusión: el Score de Boyer es una herramienta útil, rápida, fácil para el diagnóstico diferencial de la etiología de la meningitis, en cuya asociación con otros marcadores biológicos aumenta su sensibilidad y especificidad.


Introduction: meningitis is a clinical syndrome that carries risks in morbidity and mortality especially in pediatric patients, the variability of the dependent clinical manifestations of age, has allowed the use of scores that allow objectify decisions on etiological possibilities and therapeutic criteria, as in the case of "Boyer Score". Objective: to determine the validity of Score Boyer and utility in the differential diagnosis of bacterial and non-bacterial meningitis. Methods: this study is analytical, longitudinal, prospective, conducted in the period from March 2014 to January 2015 in the Children's Hospital Manuel Ascencio Villarroel. The study group was made up of 32 patients between the ages of 1 month to 15 years who were diagnosed with meningitis by clinical, laboratory, and cytochemical CSF. Results: we found that 25% of the population presented the diagnosis of bacterial meningitis confirmed positive CSF culture. Boyer's score in this study showed a specificity of 92% and a sensitivity of 100 % for the differential diagnosis of bacterial meningitis. Conclusion: the Score Boyer is a useful, fast, easy for the differential diagnosis of the etiology of meningitis, whose association with other biological markers increases the sensitivity and specificity tool.

ABSTRACT

Objetivo: comprobar si un predominio de polimorfonucleares en el líquido cefalorraquídeo de pacientes neonatales con meningitis aséptica es frecuente y si tiene relación con el tiempo de evolución de la infección. Métodos: estudio retrospectivo de recién nacidos con meningitis aséptica, que ingresaron en el Servicio de Neonatología del Hospital Pediátrico Universitario "Juan M. Márquez", entre los años 1992-2007. Se analizaron las características de los leucocitos en el examen citoquímico del líquido cefalorraquídeo y su relación con el tiempo de evolución de la infección. Resultados: la mayoría de los 291 pacientes mostraron conteo de leucocitos del líquido cefalorraquídeo con valores en la mediana discretamente elevados. Los valores medios para el porcentaje de leucocitos polimorfonucleares estuvieron por debajo del 40 % para cualquiera de los intervalos de progresión de tiempo en la evolución de la infección. El análisis del tiempo de duración de la infección previa al diagnóstico de meningitis aséptica con el conteo de leucocitos y conteo absoluto y diferencial de polimorfonucleares en el líquido cefalorraquídeo, mostró que no hay relación estadística significativa, por lo que no dependen linealmente del tiempo de duración de la infección. Conclusiones: el predominio de polimorfonucleares en el líquido cefalorraquídeo no se circunscribe a las primeras horas de la infección y no depende del tiempo de duración de la infección.


Objective: to confirm whether polymorphonuclear leukocytes frequently predominate in the cerebrospinal fluid of neonates with aseptic meningitis and whether there is association between this predominance and time of the infection progression. Methods: a retrospective study of newborns with aseptic meningitis, who were admitted to the neonatology service of "Juan M. Marquez" university pediatric hospital from 1992 to 2007. The characteristics of leukocytes were analyzed in the cytochemical test and their association with the time of infection progression. Results: most of the 291 patients had slightly high median values in their leukocyte count. Regarding the percentage of polymorphonuclear leukocytes, the average values were below 40 % for any of the time intervals of the infection progression. The analysis of the infection duration prior to the diagnosis of aseptic meningitis with leukocyte count and with absolute and differential polymophonuclear count in the cerebrospinal fluid showed that there was neither significant statistical association nor linear dependence on the length of time of infection duration. Conclusions: the predominance of polymorphonuclears in the cerebrospinal fluid is not restricted to the first hours of infection and does not depend on the time of infection duration.

ABSTRACT

Objetivo: exponer las características clínicas y epidemiológicas de la meningitis aséptica, probablemente enteroviral, en recién nacidos atendidos en nuestro servicio de neonatología. Métodos: estudio retrospectivo de 291 pacientes recién nacidos ingresados en el servicio de neonatología del Hospital Pediátrico Universitario "Juan M. Márquez", entre los años 1992-2009, con el diagnóstico de meningitis aséptica. La información se obtuvo de una base de datos creada para una investigación sobre meningitis neonatal. Se analizaron diversas variables clínicas y epidemiológicas de presentación de esta enfermedad. Resultados: ocurrieron picos de incremento de la incidencia de la meningitis aséptica, con una tendencia estadísticamente significativa a disminuir en el transcurso de los 18 años (p= 0,00027). La frecuencia de presentación mostró una agrupación de casos hacia los meses de junio a noviembre. La fiebre estuvo presente en todos los pacientes, seguida por la irritabilidad y la presencia de diversas manifestaciones del aparato respiratorio. La apariencia de niño enfermo y las convulsiones fueron manifestaciones poco frecuentes. Exceptuando la pleocitosis, los indicadores convencionales en el líquido cefalorraquídeo y la relación glucosa líquido cefalorraquídeo/sangre tuvieron una mediana dentro de los límites normales para el período neonatal, sin embargo, los rangos fueron amplios. Hubo pacientes con pleocitosis importante, otros con predominio de los polimorfonucleares en una proporción mayor del 50 % y también con relación glucosa líquido cefalorraquídeo/sangre baja. La evolución clínica de todos los pacientes fue favorable sin secuelas neurológicas inmediatas aparentes. Conclusiones: los episodios de meningitis aséptica ocurridos siguen un patrón característico de las infecciones enterovirales con agrupación de casos estacional y picos epidémicos periódicos. La expresión clínica de la infección y los resultados en los exámenes de biometría hemática y del examen citoquímico del líquido cefalorraquídeo, aunque característicos de una infección de esta índole, tienen amplia variabilidad, pues puede haber pacientes que presenten hallazgos que se asemejan a los observados en pacientes con meningitis bacteriana, lo cual puede crear incertidumbre clínica al médico que evalúa el paciente.


Objective: to show the clinical and epidemiological features of the aseptic meningitis, potentially by enterovirus in newborns seen in our service of Neonatology. Methods: a retrospective study was conducted in 291 neonatal patients admitted in the Neonatology service of the "Juan Manuel Márquez" Children Hospital from 1992 to 2009, diagnosed with aseptic meningitis. Information was collected from a database created for a research on neonatal meningitis. Different clinical and epidemiological variables of presentation of this disease were analyzed. Results: there were peaks of increase in the incidence of the aseptic meningitis with a statistically significant trend to decrease within the 18 years old (p= 0.00027). The frequency of presentation showed a grouping of cases towards June to November. The fever was present in all patients, followed by irritability and presence of different manifestations of respiratory tract. The appearance of the sick child and the convulsions were no more frequent manifestations. Excepting for the pleocytosis, the conventional indicators in the cerebrospinal fluid/blood had a mean within the normal limits for the neonatal period, however, the ranks were wide. There were patients presenting with a significant pleocytosis, other with predominance of polimorphonuclear ones in a ratio higher than 50 % and also a low relation of glucose-cerebrospinal fluid/blood. The natural history of all patients was favorable without neurological immediate obvious sequelae. Conclusions: the episodes of aseptic meningitis occurred have a pattern characteristic of the enterovirus infections with seasonal grouping of cases and periodical epidemic peaks. The clinical expression of the infection and the results in examinations of hematic biometry and the cytochemistry examination of the cerebrospinal fluid, although characteristic of a infection like this, have a wide variability, since could to be patients with findings resembling that observed in patients presenting with bacterial meningitis, creating a clinical uncertainty for physician assessing the patient.

ABSTRACT

Human herpesvirus 7 (HHV-7) may cause encephalomyelitis in immune competent adults. We report two patients infected by the virus. A 34-year-old male presenting with paraparesis and a sensitive deficiency located in D6 dermatome. Cerebrospinal fluid had 35 white blood cells per mm³ and 75 mg protein per dl. A PCR-microarray examination was positive for HHV-7. The patient was treated with prednisolone and ganciclovir with full recovery. A 27-year-old male presenting with headache, fever and diarrhea. Cerebrospinal fluid analysis showed 160 cells per mm³ and 75 mg protein per dl. Viral RNA detection was positive for HHV-7. The patient was managed with analgesia and rest and was discharged with the diagnosis of viral meningitis. Our communication supports the notion that HHV-7 may be considered as pathogen factor in humans, even in immune competent ones.

ABSTRACT

INTRODUCCIÓN. Trabajos publicados recientemente han destacado el hallazgo de meningitis aséptica (MA) en lactantes pequeños, concomitante con infección del tracto urinario (ITU). El objetivo de esta investigación fue determinar la frecuencia de tal presentación. MÉTODOS. Se realizó un estudio descriptivo, retrospectivo que incluyó a 626 recién nacidos con ITU, ingresados en el Hospital Pediátrico Universitario Juan Manuel Márquez entre febrero de 1992 y diciembre de 2008, y a quienes se les realizó una punción lumbar. Se comparó la frecuencia de MA e ITU con los informes documentados en la literatura médica. RESULTADOS. La frecuencia de MA concomitante con ITU fue del 7,0 por ciento (IC 95 por ciento: 4,9-9,1 por ciento). Los resultados promedio del examen citoquímico del líquido cefalorraquídeo mostraron que la pleocitosis fue el indicador más notable entre los que comúnmente se miden. La frecuencia encontrada fue similar a la de los informes internacionales. CONCLUSIONES. Es llamativa la incidencia de MA concomitante con ITU en los recién nacidos y en concordancia con lo reportado internacionalmente. La concomitancia de MA e ITU puede ser multifactorial, y es posible que se presenten factores causales en algunos pacientes, o casuales en otros casos


INTRODUCTION. Papers recently published have emphasized the finding of the aseptic meningitis (AM) in small infants, concomitant with a urinary tract infection (UTI). The aim of present research was to determine the frequency of this type of presentation. METHODS. A retrospective and descriptive study was conducted including 626 newborns presenting with UTI, admitted in the Juan Manuel Márquez University Children Hospital between February, 1992 and December, 2008 who underwent a lumbar puncture. The AM and UTI frequency was compared with informed reports in medical literature. RESULTS. The frequency of AM concomitant with UTI was of 7.0 percent (95 percent CI. 4,9-9,1 percent). The mean results of cytochemical examination of cerebrospinal fluid (CSF) showed that pleocytosis was the more remarkable indicator among those usually measured. The frequency found was similar to that of international reports. CONCLUSIONS. It is interesting the incidence of AM concomitant with UTI in newborns and in concordance with that reported at international level. The AM and UTI concomitant feature may be multifactor, and it is possible the presence of causal factors in some patients or casual in other cases.

ABSTRACT

INTRODUCCIÓN. El objetivo de esta investigación fue presentar la experiencia en antibioticoterapia en recién nacidos (RN) febriles con pleocitosis del líquido cefalorraquídeo (LCR) y presunción médica de meningitis viral. MÉTODOS. Se realizó un estudio retrospectivo con 310 RN con diagnóstico de meningitis aséptica, ingresados en el Servicio de Neonatología del Hospital Pediátrico Universitario Juan Manuel Márquez entre 1992 y 2009. Se determinó, utilizando estadística descriptiva, la indicación o no de tratamiento antibiótico, momento y motivos de la indicación. RESULTADOS. Hubo 204 RN (65,8 por ciento) con meningitis aséptica que egresaron favorablemente sin haber recibido tratamiento antibiótico. En 106 RN (34,2 por ciento) se indicaron antibióticos (en 76 inmediatamente al diagnóstico de meningitis y en 30 casos, mediatamente por diversos motivos). Los motivos para tratamiento inmediato fueron principalmente los resultados del examen citoquímico del LCR muy semejantes a los de una meningitis de causa bacteriana y los antecedentes de fiebre elevada o persistente. En la indicación mediata el principal motivo fue la concurrencia de infección del tracto urinario. En los pacientes que nunca recibieron tratamiento antibiótico, la mediana de estadía hospitalaria fue de 4 días (intervalo intercuartil 3-5 días) y para los que sí lo recibieron fue de 5 días (intervalo intercuartil 4-7 días) (p < 0,0001). CONCLUSIONES. Es aconsejable revisar el enfoque de utilizar tratamiento antibiótico ante todo RN proveniente de la comunidad cuando se encuentra pleocitosis del LCR y se presume la existencia de una meningitis viral, siempre y cuando existan condiciones de vigilancia profesional calificada y continua, y un laboratorio de microbiología con recursos suficientes para respaldar una estrategia de tratamiento con uso racional de la antibioticoterapia


INTRODUCTION. The aim of present research was to present the antibiotic-therapy experience in febrile newborn (NB) presenting with cerebrospinal fluid pleocytosis (CSFP) and supposed viral meningitis. METHODS. A retrospective study was conducted in 310 NB diagnosed with aseptic meningitis admitted in the Neonatology Service of the Juan Manuel Márquez Children University Hospital between 1992 and 2009. Using the descriptive statistic method the indication or not of antibiotic treatment, moment and indication reasons were determined. RESULTS. There were 204 NB (65,8 percent) presenting with aseptic meningitis favorably discharged without antibiotic treatment. In 106 NB (34,2 percent) antibiotics were prescribed (in 76 immediately to be diagnosed with meningitis and in 30 cases, due to different reasons. The reasons for immediate treatment were mainly the results of cytochemical examination of CSF very similar to that of bacterial meningitis and backgrounds of a high or persistent fever. In mediate indication the main reason was the concurrence urinary tract infection. In patients that never were received antibiotic treatment, the hospital stay mean was of 4 days (inter-quartile interval 3-5 days), and for those that received treatment it was of 5 days (inter-quartile 3-7 days) (p < 0,0001). CONCLUSIONS. It is advisable to review the approach to use the antibiotic treatment in the case of a NB from the community when there is CSF pleocytosis and the supposed existence of viral meningitis provided that there are conditions of qualified and continuous professional surveillance and a laboratory with enough resources to support a treatment strategy with a rational use of the antibiotic therapy

ABSTRACT

El objetivo de este trabajo fue evaluar los aspectos clínicos, análisis de laboratorio, el perfil etiológico y las características evolutivas de los distintos tipos de meningitis aguda atendidos en un Servicio de Pediatría de un Hospital Público Universitario. Fueron evaluados a partir de un estudio descriptivo y retrospectivo de niños atendidos en el Servicio de Pediatría del Hospital de Clínicas de la Universidad Federal del Paraná, durante el periodo entre enero 2003 a enero 2007, con el diagnóstico probable de meningitis basado en manifestaciones clínicas y en alteraciones citológicas y bioquímicas del LCR. Se diagnosticó meningitis viral (MV) en 140 niños (45%), meningitis bacteriana (MB) en 58 (19%) y en 114 la etiología fue indeterminada (36%). Entre las MB el agente etiológico más frecuente fue Neisseria meningitidis (25 casos). Lo datos clínicos predominantes fueron fiebre, vómitos y cefalea. En el LCR de la MB hubo predominio de polimorfonucleares, proteína elevada y glucosa baja. En la MV predominaron los mononucleares. Las complicaciones neurológicas fueron más frecuentes en la MB, siendo la convulsión el hallazgo más común (6/58 pacientes). El óbito ocurrió en un caso en la MV y tres en la MB. Se llegó a la conclusión de que la clásica tríada fue la manifestación clínica más común, las anormalidades citológicas y bioquímicas fueron típicas auxiliando en la diferenciación entre las MB y MV, aunque un gran número de casos haya quedado sin definición etiológica; las complicaciones neurológicas inmediatas y los óbitos han sido pocos frecuentes en esta muestra.


The aim of this study is to evaluate the clinical and laboratorial aspects, as well as the etiological profile and the evolution characteristics, of the diverse types of severe meningitis treated at a Pediatric Clinic of a public university hospital. From a descriptive and retrospective study, 312 children at the Pediatric Clinic of the Hospital de Clínicas of the Federal University of Paraná were evaluated between January 2003 and January 2007. All of them had a probable diagnosis of meningitis based on clinical signs, and on the cytological and biochemical alterations in the cerebrospinal fluid routine examination. Viral meningitis (VM) was present in 140 children (45%), 58 had bacterial meningitis (BM - 19%) and etiology was undetermined in 114 (36%). In MB, Neisseria meningitidis was the most frequent etiological agent (25 cases). Predominant clinical symptoms were fever, sickness and headache. The cerebrospinal fluid test showed a high number of polymorphonuclear leukocytes, high protein and low glucose level in MB; mononuclear cells were predominant in VM. Neurological complications were more frequent in BM, and convulsion the most common symptom (6/58 patients). Death happened to one case in VM and 3 in BM. Our conclusions were that the classical triad (headache, vomiting and fever) was the most common clinical manifestation, the cytological and biochemical abnormalities were typical, helping in the differentiation of MB from VM, although a good number of cases ended up with no etiological definition and, finally, immediate neurological complications and death were rare.

ABSTRACT

OBJECTIVE: To compare children with confirmed bacterial meningitis (CBM) and those with culture- and latex-negative meningitis (CLN). METHODS: Children 1 to 59 months of age admitted to three major referral hospitals in Guatemala City with clinical signs compatible with bacterial infections were evaluated prospectively between 1 October 1996 and 31 December 2005. Bacterial cultures and latex agglutination antigen testing were performed on samples of cerebrospinal fluid (CSF). RESULTS: The case-fatality rate was significantly higher in the 493 children with CBM than in the 528 children with CLN (27.6 percent and 14.9 percent, respectively; P < 0.001). Children with CBM were less likely to have received antibiotics and more likely to have seizures, shock, or coma on admission than children with CLN. Among the 182 CBM survivors and 205 CLN survivors studied between October 2000 and December 2005, clinically observed sequelae were present at discharge in a higher percentage of the CBM than of the CLN group (78.6 percent and 46.8 percent, respectively; P < 0.0001). CSF glucose < 10 mg/dL, peripheral neutrophils < 2 000 cells/mm³, coma or shock at admission, and concurrent sepsis or pneumonia were risk factors for mortality in children with CBM; only coma or shock at admission predicted mortality in children with CLN. CONCLUSIONS: The high case-fatality and sequelae rates suggest that many children with CLN may have had bacterial meningitis. Estimates based on confirmed meningitis alone underestimate the true vaccine-preventable disease burden. Additional studies to determine etiologies of CLN in this population are indicated.


OBJETIVO: Comparar los casos infantiles de meningitis bacteriana confirmada (MBC) y meningitis negativa a pruebas de látex y de cultivo (MNLC). MÉTODOS: Se evaluaron los niños de 1 a 59 meses de edad ingresados en tres grandes hospitales de referencia de la Ciudad de Guatemala entre el 1 de octubre de 1996 y el 31 de diciembre de 2005 con signos clínicos de infección bacteriana. Se realizaron cultivos bacterianos y pruebas de aglutinación antigénica con látex en muestras de líquido cefalorraquídeo (LCR). RESULTADOS: La tasa de letalidad fue significativamente mayor en los 493 niños con MBC que en los 528 niños con MNLC (27,6 por ciento y 14,9 por ciento, respectivamente; P < 0,001). Los niños con MBC tuvieron menor probabilidad de recibir antibióticos y mayor de sufrir convulsiones, choques o entrar en coma al ser ingresados que los niños con MNLC. Se observó un mayor porcentaje de manifestaciones clínicas de secuelas al alta hospitalaria en los 182 niños sobrevivientes con MBC que en los 205 sobrevivientes con MNLC estudiados entre octubre de 2000 y diciembre de 2005 (78,6 por ciento y 46,8 por ciento, respectivamente; P < 0,0001). Los factores de riesgo de muerte en los niños con MBC fueron: glucosa en LCR < 10 mg/dL, neutrófilos periféricos < 2 000 células/mm³, coma o choque al ingreso, y sepsis o neumonía concurrentes; solo el coma y el choque al ingreso predijeron la muerte en niños con MNLC. CONCLUSIONES: Las altas tasas de letalidad y de secuelas indican que muchos niños con MNLC pueden haber tenido meningitis bacteriana. Las estadísticas basadas solamente en los casos confirmados de meningitis subestiman la verdadera carga de enfermedad prevenible mediante vacuna. Se deben emprender estudios adicionales para determinar las etiologías de la MNLC en esta población.

ABSTRACT

Los Enterovirus, agentes más frecuentes de meningitis virales, circulan durante todo el año en los países del trópico, pudiendo ocasionar un aumento en el número de casos esperados. Confirmar la existencia de un brote de meningitis viral en el Distrito Metropolitano. Descripción de las características demográficas y epidemiológicas de los niños de 1 mes a 12 años que egresaron con diagnóstico de meningitis aséptica, entre marzo y agosto de 2007, de los hospitales Universitario de Caracas y Elías Toro. Un total de 195 niños con edad promedio de 6.05 años y procedentes de 14 parroquias del Distrito Metropolitano cumplieron con los criterios (142 del HUC y 53 HET). Las características clínicas y paraclínicas de los niños coincidieron con lo reportado en la literatura. El núcleo familiar estuvo conformado en promedio por 3 adultos y 3 niños. El consumo de agua fue directamente del chorro o pipotes en 37 por ciento de las familias. El 63 por ciento restante refirieron agua hervida, filtrada o comercializada. En 2 niños se registró el inicio de los síntomas dentro de los 7 días del retorno al área Metropolitana. De 261 punciones realizadas, se estudiaron 54 en LCR para aislamiento viral: 17 con Enterovirus no polio, 4 Echovirus 30 y dos muestras con Echovirus 25. Se demostró un brote de meningitis viral en el Distrito Metropolitano, causado por Echovirus 25 y 30. Mantener informado al médico ante situaciones de brote, a fin de disminuir la transmisión del virus.

ABSTRACT

Se realizó un estudio retrospectivo a fin de describir un brote epidémico de meningitis causado por enterovirus, que comprometió a 143 niños de 1 mes a 14 años internados en el Hospital Pediátrico de Posadas (Misiones) con diagnóstico de meningitis aséptica, entre agosto y diciembre de 2005. Se observó un aumento de casos entre las semanas 33 a 50, con un pico máximo entre las semanas 47 y 48, lo que confirmó el brote. La mediana de edad de los niños afectados fue de 8 años y el 55,2% fueron varones. El 80% de los casos se observó entre escolares (5 a 14 años). El promedio del tiempo de internación fue de 4,5 ± 1,7 días, y no se registraron fallecidos. Los LCR se estudiaron mediante examen citoquímico y estudios bacteriológicos y virológicos (aislamiento viral, RT- PCR anidada e identificación molecular mediante secuenciación génica). Los recuentos de células en LCR variaron entre 6 y 5040 células /mm3, el 92% fueron inferiores a 500 células/mm3 y el 43,5% mostró predominio linfocitario. El 56% presentó concentraciones de glucosa normal, con proteínas ligeramente elevadas. El 28% de las muestras estudiadas por cultivo (17/60) mostró efecto citopático, compatible con enterovirus. La RT-PCR anidada permitió detectar enterovirus en un 73% de las muestras (43/59), con 6 casos que se tipificaron como echovirus tipo 4. El índice de positividad al combinar ambas técnicas alcanzó el 83%.


A descriptive retrospective study was carried out to describe an epidemic outbreak of enteroviral meningitis in Misiones. We reviewed records of 143 children from 1 month to 14 years of age who were hospitalized with aseptic meningitis in the Pediatric Hospital of Posadas from August to December 2005. Increased number of cases was observed between weeks 33 to 50 which reached a maximum peak in weeks 47 and 48, confirming an outbreak. The median of age was 8 years old, 55.2% were males. Eighty percent of cases were in 5 to 14 years old children. The average length of time spent in the hospital was 4.5±1.7 days, no deaths were reported. We performed cell counts, chemical and bacterial studies of CSF, and culture or RT-Nested/PCR for enteroviruses. Isolates were serotyped by RT-PCR amplification and genetic sequencing. Cell counts were from 6 to 5040 cells/mm3. Ninety two percent had less than 500 cells/mm3 and 43.5% had lymphocyte predominance. Glucose levels were normal with slightly elevated protein counts in 56% of cases. Of the cultured samples, 28% (17/60) showed cytopathic effect compatible with enterovirus. RT-n-PCR detected enterovirus in 73% (43/59) of the analyzed CSF. Echovirus type 4 was identified in 6 of them. The positive indicator obtained by combining both techniques was 83% (58/70).

ABSTRACT

Objective To analyze clinical materials and follow-up results of acute ECHO viral encephalitis in 35 children for improving recognition of this disease.Methods A total of 35 cases of acute ECHO viral encephalitis were retrospectively analyzed and followed-up,which were diagnosed.Results The clinical manifestations were as follows:headache(35 cases,100%),fever(35 cases,100%),vomiting(27 cases,77%),convulsion(8 cases,23%), positive meningeal irritation syndrome(30 cases,85%);the number of cells was(0~0.136)?10~9/L and the peak of protein was 0.8g/L in spinal fluid.30 cases(86%)had abnormal electroencephalogram,10 of which had abnormal CT scanning.18 patients were followed up,and 3(11%)of them had epilepsy seizure.The time of recovery of elec- troencephalogram was different and the longest time was 8 months.Conclusion The clinical features of ECHO viral encephalitis are non-specific of which mainly is meningoencephalitis with slighter state and better comprehensive treatment.The time for recovery of electroencephalogram is longer.Only few patients have epilepsy sequelae.

ABSTRACT

Viral meningitis is an infected central nervous system, common in children. There are many causes of disease with different incidences depended on the climate, geographical position. The most causes are Enterovirus, Arborvirus... Diagnosis is based on epidemiological, clinical, and paraclinical factors. There isn't specific treatment, only managements of symptoms, so preventive methods such as immune prevention, isolation... are very important
