[Successful treatment with chloramphenicol in four pediatric cases of intractable bacterial meningitis].

Chloramphenicol (CP) is recently one of the rarely-used antibiotics. In this study, we present four patients with intractable bacterial meningitis, who were successfully treated with CP and discuss the therapeutic indications of CP in these pediatric cases. The patients were diagnosed as bacterial meningitis at the ages ranging from 2 months to 1 year and 4 months. The causative organisms found in three of the patients were H. influenzae and in the fourth patient, S. pneumoniae. According to the microbial sensitivity tests, these organisms were highly sensitive to antibiotics including ceftriaxone, meropenem and/or panipenem/betamipron. Treatment with these antibiotics was initially effective; however, recurrences of meningitis appeared in all patients. Administration of CP (100 mg/kg/day) started between the 11th and the 58th days, and was continued for 9 days up to 19 days. Their fever had disappeared within four days after the administration of CP, and it was confirmed that all patients completely recovered from meningitis. Two of the patients developed a mild degree of anemia, but soon recovered after the discontinuation of CP. None of them had neurological sequela. We recommend CP as one of the choices for the treatment of intractable bacterial meningitis.
