Some individuals have higher efavirenz plasma concentrations during rifampin-containing tuberculosis (TB) therapy, contrary to the expected induction effect of rifampin. Among HIV-infected patients without (n = 38) and with TB on rifampin-containing therapy (n = 18), we tested the hypothesis that drug-gene interaction may explain the highly variable drug interactions. Two-way analysis of variance revealed a significant interaction between CYP2B6 516G→T polymorphism and rifampin-containing therapy, suggesting that efavirenz dose adjustment may need to be individualized on the basis of the patient's genotype.
在利福平含结核病(TB)治疗期间,一些个体的依非韦伦血浆浓度升高,与利福平预期的诱导作用相反。在未接受(n = 38)和接受利福平含治疗的 HIV 感染患者中(n = 18),我们检验了药物-基因相互作用可能解释这种高度可变的药物相互作用的假设。双向方差分析显示 CYP2B6 516G→T 多态性与利福平含治疗之间存在显著相互作用,表明可能需要根据患者的基因型来个体化调整依非韦伦剂量。
