Comparison of the efficacy and safety of ceftriaxone to ampicillin/chloramphenicol in the treatment of childhood meningitis.

Ceftriaxone is a new cephalosporin with a broad spectrum of antibacterial activity and unique serum and CSF pharmacokinetics. The drug was compared in a randomized fashion with ampicillin and chloramphenicol in the treatment of 19 children with Haemophilus influenzae type b meningitis. Ceftriaxone was also administered non-randomly to six other patients including three children with Gram-negative meningitis. Among the children with H. influenzae meningitis, no deaths were noted and the outcomes of the study and the control groups were similar. Ninety per cent of the isolates of H. influenzae were inhibited by 0.0625, 1 and 1 mg/l of ceftriaxone, ampicillin and chloramphenicol respectively. One child with pneumococcal meningitis and two children with meningococcal meningitis recovered rapidly and without incident during ceftriaxone therapy. Three children with Gram-negative meningitis caused by multiply-drug resistant organisms were bacteriologically cured within five days of the onset of therapy. Persistent pleocytosis and neurological disabilities were noted in two at the conclusion of therapy. Ceftriaxone, as a single agent, was comparable in efficacy with traditional antimicrobial therapy usually employed in childhood meningitis.
