背景:以多替拉韦(DTG)为基础的抗逆转录病毒疗法(ART)在未使用过整合酶链转移抑制剂(INSTI)的艾滋病病毒感染者(PLWH)中很少导致病毒学失败(VF)和耐药性。因此,关于含DTG的抗逆转录病毒疗法方案所筛选出的与INSTI相关的耐药突变(DRMs)的数据有限。 方法:我们回顾了截至2023年7月发表的研究,以确定那些报告在未使用过INSTI的接受DTG治疗的PLWH中出现主要的与INSTI相关的DRMs的研究,以及那些使用标准化检测方法包含体外DTG敏感性结果的研究。 结果:我们确定了36篇出版物,报告了99名在含DTG的治疗方案中出现主要的非多态性与INSTI相关的DRMs的PLWH,以及21篇包含269个体外DTG敏感性结果的出版物。DTG筛选出的DRMs聚类为四个基本不重叠的突变途径,其特征是在四个关键位置发生突变:R263K、G118R、N155H和Q148H/R/K。82个(82.8%)病毒仅包含一种关键的DRM,包括R263K(n = 40)、G118R(n = 24)、N155H(n = 9)和Q148H/R/K(n = 9)。9个(9.1%)包含≥1种关键的DRM,8个(8.1%)仅包含其他DRMs。R263K和G118R相互呈负相关,且与N155H和Q148H/K/R呈负相关。单独的R263K使DTG敏感性中位数降低2.0倍(四分位距:1.8 - 2.2)。单独的G118R使DTG敏感性中位数降低18.8倍(四分位距:14.2 - 23.4)。单独的N155H使DTG敏感性中位数降低1.4倍(四分位距:1.2 - 1.6)。单独的Q148H/R/K使DTG敏感性中位数降低0.8倍(四分位距:0.7 - 1.1)。当关键的DRMs与其他与INSTI相关的DRMs同时出现时,敏感性降低的程度往往更高。 结论:在出现VF且治疗过程中出现与INSTI相关的DRMs的未使用过INSTI的PLWH中,大多数出现了四种关键的DRMs中的一种,最常见的是R263K或G118R。G118R与DTG敏感性的降低程度比R263K大得多。
Background: Dolutegravir (DTG)-based antiretroviral therapy (ART) rarely leads to virological failure (VF) and drug resistance in integrase strand transfer inhibitor (INSTI)-naïve persons living with HIV (PLWH). As a result, limited data are available on INSTI-associated drug resistance mutations (DRMs) selected by DTG-containing ART regimens. Methods: We reviewed studies published through July 2023 to identify those reporting emergent major INSTI-associated DRMs in INSTI-naïve PLWH receiving DTG and those containing in vitro DTG susceptibility results using a standardized assay. Results: We identified 36 publications reporting 99 PLWH in whom major nonpolymorphic INSTI-associated DRMs developed on a DTG-containing regimen and 21 publications containing 269 in vitro DTG susceptibility results. DTG-selected DRMs clustered into four largely non-overlapping mutational pathways characterized by mutations at four signature positions: R263K, G118R, N155H, and Q148H/R/K. Eighty-two (82.8%) viruses contained just one signature DRM, including R263K (n = 40), G118R (n = 24), N155H (n = 9), and Q148H/R/K (n = 9). Nine (9.1%) contained ≥1 signature DRM, and eight (8.1%) contained just other DRMs. R263K and G118R were negatively associated with one another and with N155H and Q148H/K/R. R263K alone conferred a median 2.0-fold (IQR: 1.8–2.2) reduction in DTG susceptibility. G118R alone conferred a median 18.8-fold (IQR:14.2–23.4) reduction in DTG susceptibility. N155H alone conferred a median 1.4-fold (IQR: 1.2–1.6) reduction in DTG susceptibility. Q148H/R/K alone conferred a median 0.8-fold (IQR: 0.7–1.1) reduction in DTG susceptibility. Considerably higher levels of reduced susceptibility often occurred when signature DRMs occurred with additional INSTI-associated DRMs. Conclusions: Among INSTI-naïve PLWH with VF and treatment emergent INSTI-associated DRMs, most developed one of four signature DRMs, most commonly R263K or G118R. G118R was associated with a much greater reduction in DTG susceptibility than R263K.
