Background We aimed to assess the kinetics of drug-resistant viral variants (DRVs) harboring the M184V mutation in proviral DNA of long-term virally suppressed patients, and factors associated with DRV persistence. Methods Human immunodeficiency virus (HIV) DNA from blood cells stored in 2016 and 2019 was sequenced using Sanger and ultradeep sequencing (SS and UDS; detection threshold 1%) in antiretroviral therapy (ART)-treated patients with HIV RNA < 50 copies/mL for at least 5 years, with past M184V mutation documented in HIV RNA. Results Among 79 patients, by combining SS and UDS, M184V was found to be absent in 26/79 (33%) patients and persistent in 53/79 (67%). M184V-positive patients had a longer history of ART, lower CD4 nadir, and higher pretherapeutic HIV RNA. Among 37 patients with viral sequences assessed by UDS, the proportion of M184V-positive DRVs significantly decreased between 2016 and 2019 (40% vs 14%, P = .005). The persistence of M184V was associated with duration and level of HIV RNA replication under lamivudine/emtricitabine (3TC/FTC; P = .0009 and P = .009, respectively). Conclusions While it decreased over time in HIV DNA, M184V mutation was more frequently persistent in HIV DNA of more treatment-experienced patients with longer past replication under 3TC/FTC.

经历过治疗的病毒抑制 HIV 感染患者中存档 M184V 突变的动力学

背景 我们旨在评估长期病毒抑制患者的前病毒 DNA 中含有 M184V 突变的耐药病毒变体 (DRV) 的动力学,以及与 DRV 持续存在相关的因素。方法 使用 Sanger 和超深度测序(SS 和 UDS;检测阈值 1%)对 2016 年和 2019 年储存的血细胞中的人类免疫缺陷病毒 (HIV) DNA 进行测序,用于接受抗逆转录病毒治疗 (ART) 治疗的 HIV RNA < 1% 的患者。50 拷贝/mL 至少 5 年,过去的 M184V 突变记录在 HIV RNA 中。结果 79 例患者中,SS 和 UDS 联合发现 M184V 在 26/79 (33%) 患者中不存在,在 53/79 (67%) 患者中持续存在。M184V 阳性患者的 ART 病史较长,CD4 最低点较低,治疗前 HIV RNA 较高。在 UDS 评估的 37 名病毒序列患者中,2016 年至 2019 年间,M184V 阳性 DRV 的比例显着下降(40% 对 14%,P = .005)。M184V 的持续存在与拉米夫定/恩曲他滨下 HIV RNA 复制的持续时间和水平相关(3TC/FTC;分别为 P = .0009 和 P = .009)。结论 虽然 M184V 突变在 HIV DNA 中随时间减少,但在 3TC/FTC 下,M184V 突变在更多经历过治疗且过去复制时间更长的患者的 HIV DNA 中更频繁地持续存在。
