Hypothesis

Can metagenomic next-generation sequencing (mNGS) accurately detect varicella zoster virus (VZV) in cerebrospinal fluid for diagnosing encephalitis?

Conclusion

Metagenomic next-generation sequencing provides a rapid and accurate method for diagnosing varicella zoster virus-related encephalitis from cerebrospinal fluid samples.

Supporting Evidence

  • VZV-RE presented with common symptoms like headaches (81.2%) and fever (42.9%).
  • All patients received empiric treatment with acyclovir or valacyclovir.
  • mNGS confirmed VZV-RE within three days of admission.

Takeaway

Doctors can use a special test called metagenomic sequencing to quickly find out if a virus is causing brain problems in patients.

Methodology

This retrospective study analyzed clinical characteristics and laboratory evaluations of 28 patients diagnosed with neurological disorders using mNGS techniques applied to cerebrospinal fluid.

Limitations

The sample size was insufficient for epidemiological analysis and group comparisons, and all subjects underwent mNGS testing only without PCR confirmation.

Participant Demographics

The cohort included 11 females and 17 males with a median age of 65 years.
