2017年1月,发表在《J Antimicrob Chemother》的一项由乌干达、瑞士和美国科学家进行的研究考察了TB/HIV共感染患者中,抗TB药物浓度和药物相关毒性。

背景:因抗TB治疗而引起的毒性频繁在TB/HIV共感染患者中出现。

目的:旨在确定TB/HIV共感染患者中,抗TB药物浓度与肝毒性和周围神经病变发生率之间的关系。

方法:根据WHO指南,TB/HIV共感染患者开始标准剂量的抗TB治疗。抗TB药物浓度通过HPLC检测,检测时间为药物摄入后的1、2和4小时以及初始TB治疗后的2、8和24周。使用艾滋病科毒性表评估参与者的肝毒性,使用肌腱反射、振动感觉或症状的临床评估评价参与者的周围神经病变。Cox回归用于确定毒性和药物浓度间的相关性。

结果:268名患者入组,其中的58%为男性,中位34岁。无肝毒性或肝毒性为轻度、中度和重度的参与者中,其中位Cmax分别为6.57(IQR,4.83~9.41)μg/mL、7.39(IQR,5.10~10.20)μg/mL、7.00(IQR,6.05~10.95)μg/mL和3.86(IQR,2.81~14.24)μg/mL。具有肝毒性和不具有肝毒性的患者中,利福平的中位Cmax无差异(P=0.322)。周围神经病变和无周围神经病变的患者中,异烟肼的中位Cmax无差异,分别为2.34(1.52~3.23)μg/mL和2.21(1.45~3.11)μg/mL(P=0.49)。

结论:TB/HIV共感染患者中,利福平浓度和肝毒性,以及异烟肼浓度和周围神经病变之间无相关性。
