For both immunocompromised and immunocompetent persons,
bacterial encephalitis resulted in the longest hospital stays (34.5 and 16.5 days, respectively).
Twenty-eight patients (53.8%) were diagnosed with antibody-positive encephalitis (including anti-NMDAR, anti-GABA [sub]B , anti-Lgi1, anti-CV2, and anti-Ro), whereas 24 patients (46.2%) had antibody-negative encephalitis (including autoimmune, viral, and
bacterial encephalitis).
A high proportion (80%) of
bacterial encephalitis cases in the PHE data were unmatched, whereas a lower proportion of PHE cases designated as immune-mediated encephalitis (22%) or herpes simplex virus (HSV) encephalitis (33%) were unmatched.
