Clinical Characteristics and Epidemiology of Enteroviral Meningitis Compared to Non-Enteroviral Meningitis in Infants under 3 Months of Age / 이화의대지

ABSTRACT

OBJECTIVES: To compare the epidemiology, clinical presentation, laboratory findings, seasonality and hospital course of enteroviral meningitis (EM) and non-enteroviral meningitis (NEM) cases in infants under 3 months of age. METHODS: A retrospective chart review was performed of infants under 3 months of age or less with viral meningitis admitted to Ewha Womans University Mokdong Hospital between January 2010 and December 2016. RESULTS: EM patients were more likely to have siblings compared with NEM. Most of EM was diagnosed during the summer season. Almost 80% of EM was diagnosed between July and September. Fever lasted longer in EM patients compared to NEM. White blood cell count (WBC) from the cerebrospinal fluid was higher in EM patients compared with NEM patients. WBC in blood were lower in EM patients compared with NEM patients. C-reactive protein was lower in EM patients compared with NEM patients. Most of the patients were initially started on antibiotics therapy to rule out bacterial meningitis. EM patients received shorter duration of antibiotic treatment compared with NEM patients. CONCLUSION: This study was conducted to augment the understanding of the incidence, epidemiology, transmission in infants, clinical presentation, laboratory findings, seasonality and hospital courses of enteroviral meningitis compared to NEM. Early recognition, rapid diagnosis and proper clinical management can reduce duration of antibiotic treatment.
