Low posaconazole plasma concentrations (PPCs) have been associated with breakthrough invasive fungal infections. We assessed the correlation between pre-steady-state PPCs (obtained between days 3 and 5) and PPCs obtained during steady state in 48 patients with underlying hematological malignancies receiving posaconazole oral-solution prophylaxis. Pre-steady-state PPCs correlated significantly with PPCs obtained at steady state (Spearman r = 0.754; P < 0.001). Receiver operating characteristic (ROC) curve analysis of pre-steady-state PPCs revealed an area under the curve (AUC) of 0.884 (95% confidence interval [CI], 0.790 to 0.977) for predicting satisfactory PPCs at steady state.
泊沙康唑血浆浓度(PPCs)较低与侵袭性真菌感染的突破性发作有关。我们评估了48例接受泊沙康唑口服溶液预防的血液系统恶性肿瘤患者在达到稳态前(第3至5天)的PPCs与稳态时获得的PPCs之间的相关性。达到稳态前的PPCs与稳态时获得的PPCs显著相关(斯皮尔曼r = 0.754;P < 0.001)。对达到稳态前的PPCs进行的受试者工作特征(ROC)曲线分析显示,预测稳态时PPCs达到满意水平的曲线下面积(AUC)为0.884(95%置信区间[CI],0.790至0.977)。
