Point-of-care multiplexed diagnosis of meningitis using the FilmArray® ME panel technology.

Abstract : Infectious meningitis is a medical urgency and rapid detection of the causative pathogen into the cerebrospinal fluid (CSF) is mandatory to guide the management of patients. We compared the performances of the multiplexed PCR FilmArray® ME panel with standard microbiological analyses, for rapid diagnosis of infectious meningitis. All the CSF samples received in our routine laboratory for the diagnosis of infectious meningitis were prospectively analyzed by the FilmArray® ME panel for the detection of fourteen targets in parallel to standard routine real-time PCR assays and bacterial culture. We reviewed clinical and biological records of patients for whom a discrepant result was obtained to achieve a definite diagnosis. Among 1124 CSF samples tested over a 43-week period, 113 (10.1%) and 87 (7.74%) were positive using the FilmArray® ME panel and the standard techniques, respectively. Among 40 CSF samples which yielded discrepant results, 34 were positive only using the FilmArray® ME panel and 6 were positive only using standard techniques. A total of 16/34 (47.1%) FilmArray® ME panel-positive CSF, and 6/6 (100%) of standard technique-positive CSF were interpreted as true positive. We were able to estimate the sensitivity, the specificity, the positive predictive value, and the negative predictive value of the FilmArray® ME panel at 94.2%, 98.2%, 84.3%, and 99.4%, respectively. The FilmArray® ME panel is an efficient tool for the rapid diagnosis of infectious meningitis at the point-of-care. Its higher sensitivity compared with that of standard molecular biology and culture techniques yields an increase of true positive diagnosis.
