title: Relapse of Hemophilus influenzae type b meningitis after combined antibiotic therapy: report of a case.
abstract: Antibiotic therapy of bacterial meningitis is being reevaluated due to reports of ampicillin-resistant strains of Hemophilus influenzae type b. The infant reported had a relapse of H. influenzae type b meningitis after an excellent clinical and bacteriologic response to an initial course of combined antibiotic therapy including chloramphenicol. This relapse is postulated to be due to localized cerebral vasculitis which was not treated for a sufficient period of time during the initial course of therapy. The patient responded well to a second course of penicillin and chloramphenicol. Since the use of pencillin and chloramphenicol will be increasing, the clinician should be aware that bacteriologic relapse of H. influenzae type b meningitis may occur with chloramphenicol therapy.
