We investigated the in vitro activity of voriconazole compared to those of fluconazole and itraconazole against 566 clinical isolates of Cryptococcus neoformans from Africa (164) and the United States (402). Isolates were obtained from cerebrospinal fluid (362), blood (139), and miscellaneous sites (65). Voriconazole (MIC at which 90% of the isolates are inhibited [MIC90], 0.12 to 0.25 microg/ml) was more active than either itraconazole (MIC90, 0.5 microg/ml) or fluconazole (MIC90, 8.0 to 16 microg/ml) against both African and U. S. isolates. Isolates inhibited by >/=16 microg of fluconazole per ml were almost all (99%) inhibited by </=1 microg of voriconazole per ml. These results suggest that voriconazole may be useful in the treatment of cryptococcosis.
我们研究了伏立康唑与氟康唑和伊曲康唑相比,对来自非洲(164株)和美国(402株)的566株新生隐球菌临床分离株的体外活性。分离株取自脑脊液(362株)、血液(139株)和其他部位(65株)。伏立康唑(对90%分离株产生抑制作用的最低抑菌浓度[MIC90]为0.12至0.25微克/毫升)对非洲和美国的分离株的活性均高于伊曲康唑(MIC90为0.5微克/毫升)或氟康唑(MIC90为8.0至16微克/毫升)。每毫升氟康唑抑制浓度≥16微克的分离株几乎全部(99%)被每毫升伏立康唑抑制浓度≤1微克所抑制。这些结果表明伏立康唑可能对治疗隐球菌病有用。
