AbstractNeisseria meningitidis and Streptococcus pneumoniae are the most frequent causes of bacterial meningitis. The incidence of Haemophilus meningitis in the Netherlands is low due to successful Haemophilus influenzae type b vaccination. This implies that there is no need to take account into this microorganism in using initial empiric antimicrobial therapy for bacterial meningitis. Vomiting (especially children), headache, fever, and a stiff neck characterize acute bacterial meningitis. However, even without these signs a patient may still have acute bacterial meningitis. The characteristics in neonates are less specific. An emergency lumbar puncture should be performed in all patients with meningeal irritation or other signs of bacterial meningitis. Examination of the CSF is not indicated for convulsive children (between the ages of 6 months and 6 years) who do not exhibit other clinical signs. In patients who respond adequately to the treatment, it is not necessary to examine the CSF again. Papilloedema or focal neurological symptoms contraindicate a lumbar puncture in patients with bacterial meningitis, until CT results justify that it can be performed safely. Antibiotic treatment should not be delayed until after the CT. General practitioners should treat their patients with suspected meningococcus infection by admitting them to the hospital without first injecting antibiotics. In the Netherlands, patients with suspected pneumococcus meningitis may still be treated with benzylpenicillin. Patients with bacterial meningitis have no fluid restrictions; only in case of the syndrome of inadequate secretion of antidiuretic hormone is fluid reduction indicated. The physician is responsible for prescribing prophylaxis to family members. The Regional Health Services organize chemoprophylaxis for classmates. The latter is only indicated if at least 2 related cases occur in one month.
