%X Enteroviruses (EVs) constitute the most common cause of aseptic meningitis in both children and adults. Molecular techniques have now been recognized as the reference standard for the diagnosis of EV infections, and the rapidity of the molecular diagnosis of EV meningitis has been shown to be a determining factor in the management of patients. The rapid documentation of EV RNA in cerebrospinal fluid (CSF) is key to adapting patient management and the therapeutic regimen. To shorten the time needed for virological documentation, we implemented EV RNA detection in two point-of-care (POC) laboratories. Here, we present the results of the POC detection of EV RNA with the Xpert EV kit on the GeneXpert integrated system, and a comparison with the real-time RT-PCR (rtRT-PCR) assay routinely used in the core virology laboratory. From January to September 2009, a total of 310 CSF samples were tested. The rtRT-PCR gave 81 positive, 225 negative and four indeterminate results. POC results were concordant in 81.6% (253/310). Most of the discrepancies consisted of indeterminate results at the POC level (16%). Calculated performances (excluding the indeterminate results) of the Xpert EV kit on the GeneXpert system in POC settings were 100%, 98.9%, 97.6% and 100% for Sensibility, Specificity, positive predictive value and negative predictive value, respectively. Taken together, these results indicate that the implementation of POC detection of EV RNA can provide robust results in <4 h, and may have a significant impact on patient management, therapeutic attitude, and hospitalization costs.
