title: 875 cases of bacterial meningitis: diagnostic procedures and the impact of preadmission antibiotic therapy. Part III of a three-part series.
abstract: Data on the bacteriological findings, diagnostic measures and clinical course of 875 patients with bacterial meningitis are presented. Findings from the medical records and from a follow-up questionnaire survey of 667 of these cases revealed no significant difference between patients treated with antibiotics before admission (pretreated) and those who were not treated before admission (non-pretreated) with respect to clinical condition on admission, mortality and late sequelae. Pretreatment was, however, associated with a longer duration of symptoms. Apart from cases due to Neisseria meningitidis, there were no significant differences in diagnostic findings between pretreated and non-pretreated cases. In the group of pretreated meningococcal patients, however, positive blood cultures, pleiocytosis in the cerebrospinal fluid (CSF) and positive cultures from sites other than blood and CSF were less frequent than in the non-pretreated cases.
