A patient with azole-refractory thrush-esophagitis responded initially to caspofungin, but the treatment eventually failed. In a murine model, caspofungin was effective against two early isolates for which the MICs of caspofungin were low, but it was less effective against a late isolate for which the MIC of caspofungin was greater. We concluded that there is a correlation between in vivo failure and rising in vitro caspofungin MICs.
一名患有唑类难治性鹅口疮食管炎的患者最初对卡泊芬净有反应,但治疗最终失败。在小鼠模型中,卡泊芬净对两种早期分离株有效,其对卡泊芬净的最低抑菌浓度较低,但对一种晚期分离株效果较差,该分离株对卡泊芬净的最低抑菌浓度较高。我们得出结论,体内治疗失败与体外卡泊芬净最低抑菌浓度升高之间存在相关性。
