In Papua New Guinean (PNG) children with acute bacterial meningitis (ABM), all Haemophilus influenzae isolates were resistant to chloramphenicol. Although Streptococcus pneumoniae isolates had a median chloramphenicol MIC of 3 μg/ml, it was ≥4 μg/ml in 42.8%, and the likelihood of an area under the 24-hour concentration-time curve/MIC ratio of >100 h at a MIC of ≥4 μg/ml was approximately 50%. All isolates were ceftriaxone sensitive. These data support ceftriaxone rather than conventional chloramphenicol for all PNG children with suspected ABM.
在巴布亚新几内亚(PNG)患有急性细菌性脑膜炎(ABM)的儿童中,所有流感嗜血杆菌分离株均对氯霉素耐药。虽然肺炎链球菌分离株的氯霉素 MIC 中位数为 3μg/ml,但有 42.8%的分离株的 MIC 为≥4μg/ml,在 MIC 为≥4μg/ml 时,24 小时浓度-时间曲线下面积/ MIC 比值>100 h 的可能性约为 50%。所有分离株均对头孢曲松敏感。这些数据支持对所有疑似患有 ABM 的 PNG 儿童使用头孢曲松,而不是传统的氯霉素。
