Y1 - 201/07/01 UR - //www.qdcxjkg.com/content/58/1/2000955.abstract N2背景越来越多的数据表明,更高剂量的利福平更有效,缩短结核病(TB)治疗时间。本研究评估了增加利福平剂量的安全性、耐受性、药代动力学和7天和14天早期杀菌活性(EBA)。在这里,我们报告了PanACEA HIGHRIF1的最终队列结果,这是一项针对未接受治疗的涂片阳性成人结核病患者的剂量递增研究。方法患者在连续队列中接受40或50 mg·kg−1利福平单药治疗(第1 - 7天),每日1次,并在第8 - 14天之间补充标准剂量异烟肼、吡嗪酰胺和乙胺丁醇。结果在40 mg·kg−1队列(n=15)中,13例患者在单药治疗期间共发生36例不良事件,导致1例治疗中断。在50 mg·kg−1组(n=17)中,所有患者在单药治疗期间均发生不良事件,共93例;11例患者退出或停止研究用药。不良事件多为轻/中度和耐受性,与安全性无关,如胃肠道疾病、瘙痒炎、高胆红素血症和黄疸。50 mg·kg−1组与40 mg·kg−1组相比,在时间0 - 12 h (AUC0-24 h)血浆浓度-时间曲线下的利福平几何平均面积呈不成比例的增加;571 mg·L(320-995范围)vs 387(201-847范围)mg·L - 1·h,而峰值暴露量呈比例增加。 Protein-unbound exposure after 50 mg·kg−1 (11% (range 8–17%)) was comparable with lower rifampicin doses. Rifampicin exposures and bilirubin concentrations were correlated (Spearman's ρ=0.670 on day 3, p<0.001). EBA increased considerably with dose, with the highest seen after 50 mg·kg−1: 14-day EBA −0.427 (95% CI −0.500– −0.355) log10CFU·mL−1·day−1.Conclusion Although associated with an increased bactericidal effect, the 50 mg·kg−1 dose was not well tolerated. Rifampicin at 40 mg·kg−1 was well tolerated and therefore selected for evaluation in a phase IIc treatment-shortening trial.While bactericidal activity continues to increase with dose, for the first time we identified dose-limiting intolerability for rifampicin dosed at 50 mg·kg−1; 40 mg·kg−1 seems the optimal tolerable dose for evaluation in TB treatment-shortening trials https://bit.ly/37dUIuB ER -
