We retrospectively investigated prognostic factors of 27 consecutive patients with bacterial meningitis seen at Niigata University Medical and Dental Hospital between 1980 and 2006. Patients were divided into the two categories using the Glasgow outcome scale (GOS) at discharge; the poor outcome group (GOS=1 to 4; n=15) and the good outcome group (GOS=5; n=12). Poor outcome was significantly associated with the severe consciousness disturbance, and the presence of intracranial (brain swelling, seizure, cerebral hemorrhage) or systemic (pneumonia) complications. The clinical features of patients who died of bacterial meningitis (GOS=1) were almost identical to those of patients with poor outcome (GOS=1 to 4); however, the protein and sugar content in the cerebrospinal fluid in the patients who died were significant compared to the patients with good outcome (GOS=5). Pneumococcal infection was also considered to be a poor prognostic factor. Future prospective studies should be performed on a larger group of patients for establishing the prognostic factors of adult bacterial meningitis.
