A low CD4/CD8 ratio during treated HIV infection reflects heightened immune activation and predicts death. The effects of different antiretroviral therapy regimens on CD4/CD8 ratio recovery remains unclear. We performed a analysis of the MERIT study, a randomized, double-blind trial of maraviroc versus efavirenz in combination with zidovudine-lamivudine in treatment-naive HIV-infected individuals. We found higher rates of CD4/CD8 ratio normalization with efavirenz, which was driven by a greater CD8 T-cell decline.
在治疗后的 HIV 感染中,CD4/CD8 比值较低反映了免疫激活增强,并预测死亡。不同抗逆转录病毒治疗方案对 CD4/CD8 比值恢复的影响尚不清楚。我们对 MERIT 研究进行了 分析,该研究是一项在初治 HIV 感染者中比较马拉维若与依非韦伦联合齐多夫定-拉米夫定的随机、双盲试验。我们发现依非韦伦组的 CD4/CD8 比值正常化率更高,这是由于 CD8 T 细胞下降更大所致。
