Human immunodeficiency virus type 1 (HIV) primary drug resistance mutations (DRMs) influence the long-term therapeutic effects of antiretroviral treatment (ART). Drug-resistance genotyping based on polymerase gene sequences obtained by next-generation sequencing (NGS) was performed using samples from 10 ART-naïve HIV-infected men who have sex with men (MSM; P1-P10) from the acute/early to chronic stage of infection. Three of the 10 subjects exhibited the presence of major (abundance, ≥ 20%) viral populations carrying DRM at early/acute stage that later, at the chronic stage, dropped drastically (V106M) or remained highly abundant (E138A). Four individuals exhibited additional DRMs (M46I/L; I47A; I54M, L100V) as HIV minority populations (abundance, 2–20%) that emerged during the chronic stage but ephemerally.

从未接受过抗逆转录病毒疗法治疗的艾滋病毒感染男性中从感染初期到慢性的体内耐药性突变动态
人类1型免疫缺陷病毒(HIV)原发性耐药突变(DRM)影响抗逆转录病毒治疗(ART)的长期治疗效果。使用由10名未接受过ART感染的男性艾滋病毒感染男性患者(MSM; P1-P10)从急性/早期到慢性进行的样本,基于通过下一代测序(NGS)获得的聚合酶基因序列进行耐药基因分型感染阶段。10名受试者中有3名在早期/急性阶段表现出存在携带DRM的主要(大量,≥20%)病毒种群,后来在慢性阶段,其急剧下降(V106M)或保持高度丰富(E138A)。有四个个体表现出其他DRM(M46I / L; I47A; I54M,L100V)作为HIV少数群体(数量丰富,占2%至20%),这些个体出现在慢性阶段,但短暂出现。
