We describe an unusual pathway of human immunodeficiency virus type 1 reverse transcriptase resistance during therapy with tenofovir-emtricitabine, characterized initially by the mutations K70E and M184V and later by K70G and M184V, with the two mutations coexisting on the same viral genome. Phenotypic resistance to lamivudine, emtricitabine, abacavir, didanosine, and tenofovir was observed, whereas susceptibility to zidovudine and stavudine was preserved.
我们描述了在使用替诺福韦-恩曲他滨治疗期间,人类免疫缺陷病毒1型逆转录酶产生耐药性的一种不寻常途径,其最初特征为K70E和M184V突变,随后为K70G和M184V突变,这两种突变共存于同一病毒基因组上。观察到对拉米夫定、恩曲他滨、阿巴卡韦、去羟肌苷和替诺福韦具有表型耐药性,而对齐多夫定和司他夫定仍保持敏感性。
