ABSTRACT
Viral meningitis is a common infectious disease of the central nervous system (CNS) that occurs worldwide. The aim of this study was to identify the etiologic agent of lymphomonocytary meningitis in Curitiba, PR, Brazil. During the period of July 2005 to December 2006, 460 cerebrospinal fluid (CSF) samples with lymphomonocytary meningitis were analyzed by PCR methodologies. Fifty nine (12.8 percent) samples were positive. Enteroviruses was present in 49 (83 percent) samples and herpes virus family in 10 (17 percent), of these 6 (10 percent) herpes simplex virus, 1 (2 percent) Epstein Barr virus, 2 (3 percent) human herpes virus type 6 and 1 (2 percent) mixed infection of enterovirus and Epstein Barr virus. As conclusion enterovirus was the most frequent virus, with circulation during summer and was observed with higher frequency between 4 to 17 years of age. PCR methodology is an important method for rapid detection of RNA enterovirus and DNA herpesvirus in CSF.
RESUMO
A meningite viral é uma síndrome infecciosa comum do sistema nervoso central (SNC), que ocorre no mundo inteiro. O objetivo deste estudo foi identificar o agente etiológico de meningite linfomonocitária em Curitiba, PR, Brasil. Durante o período de julho de 2005 a dezembro de 2006, 460 amostras com meningite linfomonocitária foram analisadas por metodologias de PCR. Cinquenta e nove (12,8 por cento) amostras foram positivas. Enterovirus estava presente em 49 (83 por cento) amostras e herpes vírus em 10 (17 por cento), destas 6 (10 por cento) HSV, 1 (2 por cento) EBV, 2 (3 por cento) HHV- 6 e 1 (2 por cento) infecção mista de enterovírus e EBV. Conclui-se que o enterovirus foi o vírus mais frequente, com a circulação durante o verão. Houve maior número de amostras positivas entre 4 a 17 anos. A metodologia de PCR é um importante método para a detecção rápida de RNA de enterovirus e DNA do herpesvirus no LCR.
