[Epidemiological and clinical features of enteroviral meningitis: a case series of 59 adult patients]

To describe the epidemiological and clinical features of enteroviral meningitis as well as the biological profile of the cerebrospinal fluid (CSF).A retrospective study conducted in a single centre between 2004 and 2008. All aseptic meningitis due to Enterovirus were included.Fifty-nine patients were included. The triad including fever, headache and neck stiffness was reported in 62% of patients. Twelve patients (20%) had a neutrophilic leukocytosis and 23 (39%) an elevated CRP level. Twenty-eight patients (47%) had a prominent neutrophilic reaction in the CSF and nine (15.2%) had a low glucose concentration. A presumptive anti-bacterial treatment was initiated in 47 patients (80%) for an average of 3.2 days.Due to the lack of specificity of clinical features and biological manifestations of Enterovirus meningitis, the widespread use of real-time Enterovirus PCR is a priority for reducing the number of unnecessary anti-bacterial treatment. Guidelines based on clinical and biological features may be associated to help physicians in the differential diagnosis between bacterial and viral meningitides.
