Precision Diagnosis of Acute Infectious Diseases; Neuroinflammatory Cohort (PDAID)
Encephalitis, Meningitis
About this trial
This is an interventional diagnostic trial for Encephalitis focused on measuring metagenomic next-generation sequencing, microbiological diagnosis, bacterial infections, viral infections, fungal infections, parasitic infections
Eligibility Criteria
Exclusions:
- Patients on a 5150 or 5250 psychiatric hold
- Prisoners
- University of California employees / students or close associates of any of the key personnel on the study
- Outpatients and/or patients with chronic illness
Inclusion:
Demographic Criteria
- Age: any (no age limit)
- Language: any (with the use of interpreting services for obtaining consent)
For the following, the infectious syndromes include meningitis, encephalitis, fever, sepsis, and pneumonia:
Clinical Criteria
Hospital admission or transfer with diagnosis of an presumed infectious syndrome or clinical presentation consisting with an infectious syndrome, as defined below:
- Meningitis: fever >38°C and abnormal imaging or CSF pleocytosis (CSF white blood cell count (WBC) > 5 /mm^3) +/- stiff neck, +/- headache, +/- seizure
- Encephalitis: pleocytosis and at least one of the following: altered mental status, seizures, new onset of focal neurologic findings, abnormal EEG, acute brain abnormalities on neuroimaging
- No known diagnosis of non-infectious etiology responsible for symptoms
- Time of enrollment: within 7 days of onset of symptoms, either initial presentation or acute exacerbation of presumed infectious syndrome.
Specimen Criteria
- cerebrospinal fluid available within 7 days of symptom onset AND within 3 days of hospital admission or transfer unless evidence for acute exacerbation as defined by abrupt decline in clinical status, worsening pleocytosis or other laboratory parameters
- Minimum of 600 microliters (uL) of clinical sample, stored at 4 degrees Celsius (C) no more than 5 days (ideally frozen in -70 degrees Celsius within 24 hours of collection)
- No more than 3 freeze-thaw cycles

Arms of the Study
Arm 1
Experimental
patients enrolled for mNGS testing
Patients with meningitis and/or encephalitis will be enrolled in this study in order to analyze the clinical utility of mNGS for pathogen detection. There is no control group for this study (Investigators will identify historical controls by retrospective chart review and clinical reimbursement documents).
