    Abstract:
    OBJECTIVE: To evaluate the diagnostic potential of previously published enterovirus (EV) reverse transcription polymerase chain reaction (RT-PCR) assay in detection of EV in CSF samples from children with a diagnosis of aseptic meningitis and to investigate the clinical characteristics of the patients seen in Shandong. METHODS: EV RNA was detected in 187 CSF samples and serum and/or urine samples of a part of patients by RT-PCR and viral culture technique. RESULTS: RT-PCR was positive in all 62 CSF specimens which were positive by cell culture (100%). In addition, 93 of 125 (74.4%) CSF samples negative by cell culture were RT-PCR positive. In 4 of these 93 (4.3%) patients, viral culture of specimens from other sites (serum or urine) was also positive. The sensitivity of CSF RT-PCR based on clinical diagnosis in patients with meningitis of negative bacterial culture results was 82.9% (155/187), which was considerably higher than the sensitivity of CSF virus culture 33.2% (62/187). The results of RT-PCR can be reported within 4 hours, whereas the viral culture of CSF requires 4.6 days for a cytopathic effect to develop. EV meningitis occurred in a sporadic form and in some areas there were outbreaks. The clinical characteristics of 155 patients with EV meningitis were different in different age groups. CONCLUSION: EV was one of the most common causes of aseptic meningitis in Shandong area. The RT-PCR assay was rapid, sensitive and specific for the diagnosis of EV meningitis and may be a potential tests to shorten hospital stay and reduce the use of antibiotics.
