We performed bedaquiline broth microdilution susceptibility testing using Clinical and Laboratory Standards Institute (CLSI) guidelines on 103 respiratory isolates of Mycobacterium avium complex (MAC), including multidrug-resistant isolates. Approximately 90% of isolates had bedaquiline MICs of ≤0.008 μg/ml, and 102/103 isolates had MICs of ≤0.015 μg/ml. Bedaquiline has excellent potential for use in patients with MAC infections, although for reasons of its metabolism by the cytochrome P450 system, it should not be given with rifampin.
我们按照临床和实验室标准协会(CLSI)的指南,对103株鸟分枝杆菌复合群(MAC)呼吸道分离株,包括耐多药分离株,进行了贝达喹啉肉汤微量稀释药敏试验。约90%的分离株贝达喹啉最低抑菌浓度(MIC)≤0.008μg/ml,103株中有102株MIC≤0.015μg/ml。贝达喹啉在MAC感染患者中具有很好的应用潜力,不过由于其经细胞色素P450系统代谢,不应与利福平合用。
