Cerebrospinal fluid (CSF) was taken from 19 children with bacterial meningitis treated with cefotaxime (300 mg/kg of body weight/day) and vancomycin (60 mg/kg/day). Median levels of drugs in CSF were smaller than expected, as follows: 4.4 microg/ml for cefotaxime, 3.2 microg/ml for desacetylcefotaxime, and 1.7 microg/ml for vancomycin. The median CSF bactericidal titer against an intermediately cefotaxime-resistant pneumococcus was 1:4. Our data suggest at least an additive interaction between the drugs used in this study.
从19名接受头孢噻肟(300mg/kg体重/天)和万古霉素(60mg/kg/天)治疗的细菌性脑膜炎患儿中采集脑脊液(CSF)。脑脊液中药物的中位水平低于预期,具体如下:头孢噻肟为4.4μg/ml,去乙酰头孢噻肟为3.2μg/ml,万古霉素为1.7μg/ml。针对对头孢噻肟中度耐药的肺炎球菌的脑脊液杀菌效价中位数为1:4。我们的数据表明本研究中使用的药物之间至少存在相加作用。
