Glycopeptides which have excellent in vitro activity against the Gram-positive causal agents of meningitis unfortunately have a poor CSF penetration. Vancomycin distribution into CSF is improved when administered by a continuous intravenous route and staphylococcal shunt related infection have been reported to be cured. Teicoplanin has good in vitro activity against a lot of staphylococci, and activity superior to vancomycin, against streptococci and is less toxic. In three children with shunt ventriculitis (S epidermidis 2, S. faecalis 1) despite a continuous infusion, vancomycin 15 mg/kg over 60 minutes onset, then 50 mg/kg/day was clinically and bacteriologically ineffective with very poor CSF levels even if high blood levels. After failure of vancomycin we used teicoplanin as a continuous i.v. infusion 6 mg/kg over 60 mn onset, then 12 mg/kg/day. This treatment was quickly effective and well tolerated.
糖肽类药物虽然对引起脑膜炎的革兰氏阳性病原体具有出色的体外活性,但不幸的是其脑脊液穿透性较差。通过持续静脉给药时,万古霉素在脑脊液中的分布会得到改善,并且有报道称与葡萄球菌分流相关的感染已被治愈。替考拉宁对许多葡萄球菌具有良好的体外活性,对链球菌的活性优于万古霉素,且毒性较小。在三名患有分流性脑室炎的儿童(表皮葡萄球菌2例,粪肠球菌1例)中,尽管持续输注万古霉素,剂量为15mg/kg,60分钟内输注完毕,然后50mg/kg/天,但临床和细菌学上均无效,即使血液中药物浓度很高,脑脊液中的药物浓度也极低。在万古霉素治疗失败后,我们使用替考拉宁持续静脉输注,起始剂量为6mg/kg,60分钟内输注完毕,然后12mg/kg/天。该治疗迅速起效且耐受性良好。
