目的:评估齐多夫定、去羟肌苷、拉米夫定和沙奎那韦联合用药 8 周后对血浆、外周血单个核细胞 (PBMC) 和淋巴结单个核细胞 (LNMC) 的抗逆转录病毒作用。方法:10 名未接受过 HIV-1 抗逆转录病毒治疗的患者接受口服齐多夫定(200 mg,每天 3 次)、口服去羟肌苷(200 mg,每天两次)、口服拉米夫定(150 mg,每天两次)和口服沙奎那韦(600 mg,每天 3 次)的联合治疗。 HIV-1 血浆 RNA 通过定量逆转录酶 (RT)-聚合酶链反应 (PCR) 进行测量。通过共培养技术测量 PBMC 和 LNMC 中的感染性 HIV-1。通过 RT-PCR 定量 PBMC 和 LNMC 中的 HIV-1 RNA。通过终点稀释 PCR 测量 PBMC 和 LNMC 中的前病毒 DNA 滴度。通过流式细胞术分析 CD4 T 细胞。结果:所有患者的 CD4 细胞计数均有所上升(平均增加 125 ± 71 CD4 细胞 × 106/l),并且对于 CD4 细胞少于 350 × 106/l 的患者获益更大(平均增加 159 ± 74 CD4 细胞 × 106/l)。所有患者的血浆 HIV-1 RNA 均呈指数下降(8 周后平均下降 3.1 log10,平均半衰期为 2.2 ± 0.6 天)。 HIV-1 RNA 在 PBMC 中减少了 3.07 log10,在 LNMC 中减少了 2.1 log10。血浆 HIV-1 RNA 的减少与 LNMC 的减少一致相关。这些数据得到了 PBMC(平均下降 1.41 log10)和 LNMC(平均下降 2.54 log)中 HIV-1 感染滴度的伴随下降的支持。结论:这些数据显示这种四药组合在血液和淋巴组织中具有显着的抗逆转录病毒作用。然而,与淋巴结细胞相比,PBMC 和血浆中的 HIV-1 RNA 减少幅度更大。
Objective: To assess the antiretroviral effect of a combination of zidovudine, didanosine, lamivudine and saquinavir in plasma, peripheral blood mononuclear cells (PBMC) and lymph‐node mononuclear cells (LNMC) after 8 weeks. Methods: Ten HIV‐1 antiretroviral therapy‐naive patients were given a combination of oral zidovudine (200 mg three times daily), oral didanosine (200 twice a day), oral lamivudine (150 mg twice a day) and oral saquinavir (600 mg three times daily). HIV‐1 plasma RNA was measured by quantitative reverse transcriptase (RT)‐polymerase chain reaction (PCR). Infectious HIV‐1 in PBMC and LNMC was measured by a coculture technique. HIV‐1 RNA in PBMC and LNMC was quantified by RT‐PCR. Proviral DNA titres in PBMC and LNMC were measured by endpoint dilution PCR. CD4 T‐cells were analysed by flow cytometry. Results: CD4 cell counts rose in all patients (mean increase of 125 ± 71 CD4 cells × 106/l) and the benefit was greater for patients with fewer than 350 CD4 cells × 106/l (mean increase of 159 ± 74 CD4 cells × 106/l). Plasma HIV‐1 RNA decreased exponentially in all patients (mean decrease of 3.1 log10 after 8 weeks with a mean half‐life of 2.2 ± 0.6 days). HIV‐1 RNA showed a decrease of 3.07 log10 in PBMC and of 2.1 log10 in LNMC. The decrease in plasma HIV‐1 RNA was consistently associated with the decrease in LNMC. These data were supported by a concomitant drop of HIV‐1 infectious titres in PBMC (mean decrease of 1.41 log10) and in LNMC (mean decrease of 2.54 log). Conclusions: These data show a significant antiretroviral effect of this four‐drug combination in blood and lymphoid tissues. However, a greater decrease in HIV‐1 RNA was observed in PBMC and in plasma than in lymph node cells.
