New aspects of prevention and therapy of meningitis.

Cefotaxime and ceftriaxone are currently the agents of first choice for empiric treatment of bacterial meningitis in children. Further studies are necessary to determine the optimal antibiotic therapy for meningitis caused by Streptococcus pneumoniae isolates relatively or fully resistant to penicillin. The Haemophilus influenzae type b capsular polysaccharide-protein conjugate vaccines undoubtedly will alter the relative importance of the three common meningeal pathogens in pediatrics and make additional studies of the adjunctive use of dexamethasone in the treatment of bacterial meningitis even more critical.
