The CSF of all patients was collected when virus infection-like symptoms (T >38°C, headache, etc) were present. DNA sequences were extracted from samples and amplified by Applied Biosystems
TM 7500 RT-qPCR instrument (Thermo Fisher Scientific, USA). The CSF of all patients was collected when bacterial infection-like symptoms (T >38°C, neck stiffness, etc) were present, and transferred to different culture bottles (
Bactec Plus Aerobic/F,
Bactec Lytic/10 Anaerobic/F,
Bactec Peds Plus/F) (Becton, Dickinson and Company Sparks, MD 21152 USA) immediately, and underwent etiology inspection by Bacrec
TM FX automated blood culture system (Becton, Dickinson and Company, USA) in microbiological laboratory. All serum and CSF samples from patients with AE were evaluated for NSAbs by
IIF kits (Euroimmun, Lübeck, Germany) and CBA kits (Euroimmun, Lübeck, Germany) according to the manufacturer’s instructions. All patients underwent serum and CSF laboratory tests, including all of the following: CSF examinations included: Pandy test, intracranial pressure, WBC counts, protein levels, chloride, glucose, lactate dehydrogenase (LDH), lactic acid (Lac), adenosine deaminase (ADA) and C-reactive protein (CRP). Blood examinations included: leukocyte, erythrocyte and platelet counts, and the levels of sodium, potassium, calcium, and chlorine.
