성인 무균성 수막염 환자의 뇌척수액으로부터 Enteroviruses 의 분리

Background: The enteroviruses are the most common etiologic agent of aseptic meningitis in adults and children. The incidence of enteroviral meningitis in childhood meningitis is up to 80%, but in adults is not known, worldwidely. In Korea, where tuberculosis is endemic, the rapid and accurate diagnostic method for enteroviral meningitis is required especially because early differential diagnosis of viral meningitis from tuberculous meningitis is very important. The aims of this study were the demonstration of enteroviruses from cerebrospinal fluid (CSF) of adult patients with aseptic meningitis by PCR/Southern hybridization and the verification of the usefulness of PCR/southern hybridization as a rapid diagnostic tool. Methods: From July 1992 to June 1995, total 34 CSF samples (10 from children, 24 from adults) of patients with aseptic meningitis were studied. As a control group, 15 patients with tuberculous meningitis and 15 patients with bacterial meningitis were studied. Viral RNA was extracted from CSF, reverse transcriptied into cDNA and amplified. The PCR products were Southern hybridizied with enteroviruses-specific digoxigenin-labelled probe. Results: 16/24(66.7%) samples of adult patients with aseptic meningitis were positive for enteroviruses, while in child patients with aseptic meningitis, 9/10(90%) samples were positive. And in one patient, PCR was positive from asymptomatic, onset-7th day CSF sample. Conclusion: Enteroviruses were the most common causative organisms of adult aseptic meningitis in Korea. And, this study showed the usefulness of PCR/Southern hybridization of enteroviruses from CSF for etiologic diagnosis of adult aseptic meningitis in subclinical, asymptomatic period.
