Özet

AIM: Rapid diagnosis of infectious meningitis and encephalitis (ME) is essential for appropriate treatment. Rapid

syndromic tests are important tools to ensure the necessary timely diagnosis. This study evaluated the one-year

performance of the QIAstat-Dx ME panel in the routine diagnostic workflow at a university hospital.

METHODS: A total of 107 CSF samples were analyzed with the QiaStat Dx ME (QS-ME) panel between January

2022 and January 2023. Simultaneously, microscopic evaluation, biochemical analyzes and bacterial, fungal and

mycobacterial cultures were performed in CSF according to the physician’s order.

RESULTS: CSF samples were obtained from patients aged between 0 days and 90 years (mean: 28,9). Nine viruses

(Ct >20) and three bacteria (Ct <20) were detected by the panel in 12 of 107 (11.2%) samples. Detected pathogens

were: enterovirus (n:5) and parechovirus (n:1) in the infant group; HHV-6 (n:1) in the child group, HSV-1 (n:1),

S.pneumoniae (n:1) and N.meningitidis (n:1) in the adult group; VZV (n:1) and S.pneumoniae (n:1) in the elderly

group. Sample with N. meningitidis was culture negative due to antibiotic use before the lumber puncture. No

culture positive PCR negative samples were detected for the bacteria covered by the panel. The QS-ME panel was

operated 24/7, and the average time between sample acceptance and reporting of the result was 122 minutes.

CONCLUSIONS: QS-ME panel enabled the detection of pathogens in 10 samples that could not be diagnosed with

routine conventional diagnostic tests in the laboratory and provided results 24/7, within an average of 2 hours.
