我们研究了7例重度预处理的HIV-2感染患者,这些患者在接受含雷特格韦的补救治疗方案时表现出病毒学失败。在病毒学失败时,观察到不同的抗性遗传途径:T97 A-Y143 C、Q148 K、Q148 R、G140 S-Q148 R、E92 Q-Y143 R-N155 H和T97 A-N155 H。因此,尽管HIV-1和HIV-2之间整合酶基因存在40%的差异,但导致雷特格韦耐药的遗传途径相似。
We studied seven heavily pretreated HIV-2-infected patients exhibiting a virological failure while receiving a salvage raltegravir-containing regimen. At the time of virological failure, different resistance genetic pathways were observed: T97A-Y143C, Q148K, Q148R, G140S-Q148R, E92Q-Y143R-N155H, and T97A-N155H. Thus, despite a 40% difference in integrase genes between HIV-1 and HIV-2, the genetic pathways leading to raltegravir resistance are similar.
