Abstract

Assessing treatment adherence and quantifying exposure to anti-tuberculosis drugs among children is challenging. We undertook a 'proof of concept' study to assess the drug concentrations of isoniazid (INH) in hair as a therapeutic drug monitoring tool. Children aged <12 years initiated on a thrice-weekly treatment regimen including INH (10 mg/kg) for newly diagnosed tuberculosis were enrolled. INH concentrations in hair were measured using liquid chromatography-tandem mass spectrometry at 1, 2, 4 and 6 months after initiating anti-tuberculosis treatment. We found that INH hair concentrations in all children on thrice-weekly INH were detectable and displayed variability across a dynamic range.

摘要

评估儿童的治疗依从性以及量化其抗结核药物暴露情况具有挑战性。我们开展了一项“概念验证”研究,以评估头发中异烟肼(INH)的药物浓度作为一种治疗药物监测工具。纳入了年龄小于12岁、开始接受包括INH(10mg/kg)在内的每周三次治疗方案用于新诊断结核病的儿童。在开始抗结核治疗后的1、2、4和6个月,使用液相色谱-串联质谱法测量头发中的INH浓度。我们发现,所有接受每周三次INH治疗的儿童头发中的INH浓度均可检测到,并且在动态范围内呈现出变异性。
