Elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) is a potent fixed-dose, once-daily regimen for HIV-1 treatment and has rare emergence of drug resistance. We report a potential drug-drug interaction in 2 female patients both receiving treatment for HIV and cerebral toxoplasmosis: one case between E/C/F/TAF with calcium carbonate and a second case involving leucovorin as calcium salt. Both cases resulted in rise in HIV RNA levels and emergence of M184 V mutation and resistance to elvitegravir and raltegravir. To the best of our knowledge, these 2 cases are the first reports of rapid emergence of mutation from coadministration of E/C/F/TAF and calcium.
艾维雷韦/考比司他/恩曲他滨/替诺福韦艾拉酚胺(E/C/F/TAF)是一种强效的固定剂量、每日一次的HIV-1治疗方案,耐药情况罕见。我们报告了2例同时接受HIV和脑弓形虫病治疗的女性患者中可能存在的药物相互作用:1例是E/C/F/TAF与碳酸钙之间的相互作用,另1例涉及亚叶酸钙盐。两例均导致HIV RNA水平升高,出现M184V突变,并对艾维雷韦和拉替拉韦产生耐药。据我们所知,这2例是E/C/F/TAF与钙共同给药后迅速出现突变的首例报告。
