Clinical Comparison among Patients with Enteroviral Meningitis According to the Presence of CSF Pleocytosis / 대한소아신경학회지

ABSTRACT

PURPOSE: The aim of this study was to evaluate the difference of clinical features among patients with enteroviral mengitis according to the presence of cerebrospinal fluid (CSF) pleocytosis. METHODS: This was a retrospective analysis of the patients' data diagnosed with enteroviral meningitis by CSF reverse transcriptase polymerase chain reaction (RT-PCR). We reviewed the medical records of children younger than 16 years who visited Korea University Ansan Hospital and Guro Hospital for meningitis or encephalitis between March 2013 and August 2013. Clinical and laboratory variables were compared with regard to the presence of CSF pleocytosis. RESULTS: Among 49 patients with enteroviral meningitis, eight of 49 (16.3%) did not have pleocytosis. The enteroviral meningitis patients without pleocytosis had lower CSF protein level than patients with pleocytosis (18.9+/-4.3 vs 34.9+/-18.3 mg/dL; P=0.002). Age, duration of hospital stay, severity of clinical symptom, peripheral white cell blood counts, absolute neutrophil counts and CSF/serum glucose ratio were not different between two groups. CONCLUSION: Enteroviral meningitis could manifest without pleocytosis. We therefore think that CSF RT-PCR is helpful for the diagnosis, especially in suspected cases, which leads to shorter hospital stay and minimal use of antibiotics.
