The quantification of voriconazole concentration in lung epithelial lining fluid to facilitate the management of pulmonary fungal colonisation or aspergillosis is of increasing interest. An accurate and reproducible high-performance liquid chromatography method to quantify voriconazole in human bronchoalveolar lavage (BAL) fluid was developed and validated. BAL samples were concentrated by freeze-drying and reconstituted with water prior to deproteinisation. Separation was achieved with a C18 column employing fluorescence detection (excitation: 260nm, emission: 370nm). The calibration curves were linear from 2.5 to 500ng/mL. The intra- and inter-day precisions were within 7%. Accuracies ranged from 102% to 107%. The clinical applicability was established by successful measurement of voriconazole concentrations in lung transplant recipients. The assay provides an alternative approach for those with negligible access to liquid chromatography-tandem mass spectrometry instrumentation.
定量检测肺部上皮衬液中的伏立康唑浓度,有助于管理肺部真菌感染或曲霉菌感染,这引起了越来越多的关注。本研究开发并验证了一种准确且可重现的高效液相色谱法,用于检测人支气管肺泡灌洗液(BAL)中的伏立康唑浓度。BAL 样本通过冷冻干燥浓缩,并用去蛋白水复溶。采用 C18 柱,荧光检测(激发波长:260nm,发射波长:370nm)实现分离。校准曲线在 2.5 至 500ng/mL 范围内呈线性。日内和日间精密度均在 7%以内。准确度在 102%至 107%之间。该方法在肺移植受者中成功测量了伏立康唑浓度,证实了其临床适用性。该检测方法为那些几乎无法使用液相色谱-串联质谱仪器的人提供了一种替代方法。
