万古霉素(VM)被用作细菌性脑膜炎(BM)的经验疗法。我们研究了VM对BM的微生物功效与VM最低抑制浓度(MICVM)、血清VM谷浓度(VMser)和脑脊液(CSF)蛋白(P)/血清白蛋白(SA)比的关系,这可能反映了血脑屏障(BBB)破坏的程度。12例BM患者入组,其中7例(58.3%)VM微生物有效。VMser、MICVM和CSF-P/SA比值与VM的微生物功效无关。与MICVM相比,VM的微生物功效与CSF-P/SA比值(η = 0.61,p= 0.04)显著相关。这些结果表明,VMser、MICVM和血脑屏障破坏程度的组合参数可能与VM在BM患者中的微生物功效有关。
Vancomycin (VM) is used as empirical therapy for bacterial meningitis (BM). We investigated the relationship of the microbiological efficacy of VM for BM with VM minimum inhibitory concentration (MICVM), serum VM trough concentration (VMser) and cerebrospinal fluid (CSF) protein (P)/serum albumin (SA) ratio, which may reflect the extent of blood–brain barrier (BBB) disruption. Twelve BM patients were enrolled and VM was microbiologically effective in seven (58.3%). VMser, MICVM, and CSF-P/SA ratio were not associated with the microbiological efficacy of VM. The microbiological efficacy of VM was significantly associated with CSF-P/SA ratio multiplied by VMserrelative to the MICVM(η = 0.61,p= 0.04). These results indicate that the parameter combining VMser, MICVM, and the extent of BBB disruption could be associated with the microbiological efficacy of VM in BM patients.
