Abstract
Objective Meningitis and encephalitis are neurological emergencies requiring rapid diagnosis and treatment. The performance of the FilmArray® Meningitis/Encephalitis (ME) panel, a multiplex polymerase chain reaction test, and conventional methods for diagnosing meningitis and encephalitis was compared. Methods This retrospective study assessed 20 patients diagnosed with meningitis or encephalitis according to clinical symptoms and laboratory examination findings between January 2018 and December 2019. The results of the FilmArray® ME panel were compared with those of conventional methods. Results Pathogens were identified in 11 (55%) patients using the FilmArray® ME panel and in nine (45%) patients using conventional methods. The test identified herpes simplex virus type 1 in two patients, herpes simplex virus type 2 in one, varicella-zoster virus in four, Streptococcus pneumoniae in three, and Cryptococcus neoformans in one. Furthermore, additional pathogens were detected (n = 1, S. pneumoniae and n = 1, varicella-zoster virus). The median times to pathogen identification were 2 hours using the FilmArray® ME panel and 96 hours with conventional methods. Conclusions The sensitivity of the FilmArray® ME panel for rapidly detecting the most common pathogens was similar to that of conventional methods. Hence, this method could decrease the time to definitive diagnosis and treatment initiation.
