摘要:
目的 探讨病情快速进展对男男性行为者(men who have sex with men,MSM)HIV/AIDS患者高效抗逆转录病毒治疗(highly active anti-retroviral therapy, HAART)后免疫重建效果的影响。 方法 将108例MSM HIV/AIDS患者分为快速进展组(68例)、非快速进展组(40例),对2组HAART启动后24个月免疫重建相关指标的恢复情况进行分析。 结果 随着HAART的进行,2组的CD4+T淋巴细胞(CD4)计数、CD4/CD8+T淋巴细胞(CD8)(CD4/CD8比例)比例均逐渐回升,在HAART启动后24个月,快速进展组的CD4/CD8比例(0.62±0.29)低于非快速进展组(0.84±0.33)(F=4.244, P=0.042); 快速进展组的基线CD8计数(933±430) 个/μL低于非快速进展组(1 248±476) 个/μL(t=3.515, P=0.001),之后2组CD8计数逐渐回落至相似水平(F=0.110, P=0.741),快速进展组的回落幅度小于非快速进展组。 结论 对于MSM HIV/AIDS患者,病情快速进展将对HAART免疫重建效果造成负性影响。 -

Abstract:Objective To explore the effect of rapid disease progression on immune reconstitution after highly active anti-retroviral therapy (HAART) in HIV/AIDS MSM. Methods A total of 108 HIV/AIDS MSM were divided into rapid progression group (n=68) and non-rapid progression group (n=40). The recovery of immune reconstitution related indexes in two groups after HAART 24 months were statistically analyzed. Results During the progress of HAART, CD4+T cell (CD4) count and CD4/CD8+T cell (CD8) ratio in both groups gradually increased, and CD4/CD8 ratio in rapid progression group was lower than that in non-rapid progression group (0.62±0.29 vs. 0.84±0.33, F=4.244, P=0.042) after 24 months of HAART initiation. The baseline CD8 count in rapid progression group (933±430) was lower than that in non-rapid progression group (1 248±476) (t=3.515, P=0.001), and then CD8 count in both groups gradually decreased to a similar level (F=0.110, P=0.741), with smaller decline in rapid progression group than in non-rapid progression group. Conclusion For HIV/AIDS MSM, the rapid disease progression will have a negative effect on immune reconstitution of HAART. -
