[Duration of the treatment of meningitis except in the neonatal period].

Optimal treatment of bacterial meningitis raises three questions: which antibiotic? which dosage? which duration? The overall duration of antibiotherapy has been shortened since the last decade. If a short-course treatment shows similar efficacy and rate of relapse, unnecessary prolonged course of treatment exposes to increased cost, duration of hospitalization and secondary effects. From 1979, Gold et al in Toronto treated all uncomplicated cases of meningitis for seven days and obtained satisfactory results. The first randomized trials evaluating optimal duration of treatment in meningitis were performed in 1985 by Lin et al: they showed no difference in terms of efficacy and complications between conventional and short-term treatment. Current rules in meningococcal meningitis consist of seven days or less on therapy, and 7-10 days for pneumococcal or Haemophilus meningitis. The sequential follow-up of C-reactive protein (CRP) levels seems a useful tool for the management of bacterial meningitis.
