Azole resistance among clinical isolates of Aspergillus fumigatus is becoming a serious problem in Europe, but the status in Japan is not yet known in detail. The aim of this study was to determine the present status of azole resistance in A. fumigatus in Japan. We employed 171 clinical isolates of A. fumigatus sensu stricto collected from 1987 to 2008 at the Medical Mycology Research Center, Chiba University, Japan for azole resistance determination. Identification of all isolates were re-examined both from the aspect of morphology and molecular phylogeny. The antifungal susceptibility of these isolates was tested based on the CLSI M38-A2 broth microdilution method. In our collection, only 1 (0.6%) and 2 isolates (1.2%) showed elevated MIC to voriconazole and itraconazole, respectively.Our study disclosed that the frequency of azole resistance in A. fumigatus still remains low in this collection. 相似文献

Voriconazole is a broad-spectrum triazole antifungal used to treat invasive fungal infections. It is commonly used prophylactically in immunocompromized patient cohorts, including transplant recipients. Diffuse periostitis is a very rare complication of chronic voriconazole use. It is associated with diffuse bone pain, elevated serum alkaline phosphatase and fluorine levels. Characteristic imaging findings include periosteal thickening with a dense, nodular, irregular and often bilateral pattern. We describe the case of a 71-year-old female who presented with multifocal bone pain six years following double lung transplantation. Her post transplantation course had been complicated by a life threatening episode of sepsis secondary to Scedosporium apiospermum, a rare invasive fungal infection following which lifelong prophylaxis with oral Voriconazole was commenced. We discuss the characteristic clinical and imaging manifestations of this rare condition. 相似文献

BackgroundVoriconazole (VRCZ) is the first-line treatment for chronic pulmonary aspergillosis (CPA). VRCZ trough concentration monitoring is recommended for adequate therapy because VRCZ concentrations vary widely. However, factors associated with variations in VRCZ concentrations, especially in the same patient at different time points, have not been identified. The objective of this study was to identify factors influencing VRCZ trough concentrations.Patients and methodsThis single-center retrospective study conducted at our institute between April 2014 and August 2016 included patients with CPA who received VRCZ. Patient trough concentrations were measured more than twice while the patients received the same dose using the same administration route (defined as one series). A step-wise method and multiple regression analysis were used to test the effects of patient characteristics on VRCZ trough concentrations.ResultsSixty-nine series in 49 patients were analyzed. VRCZ was administered orally in 59 series, intravenously in 7 series, and by dry syrup in 3 series. The median VRCZ trough concentration and the median variation in VRCZ concentrations were 1.68 and 0.99 μg/ml, respectively. In the simple regression analysis, creatinine, alkaline phosphatase, C-reactive protein (CRP), and creatinine clearance significantly correlated with VRCZ concentrations. Multiple regression analysis demonstrated a significant positive correlation between CRP and VRCZ concentration (P < 0.0001).ConclusionIn patients with CPA, VRCZ concentration correlated with CRP levels in the same patients receiving the same dose of VRCZ at different time points. 相似文献
