我们观察了 36 名 HIV 感染者,以评估基线时外周血单核细胞 (PBMC) 中串联 2 长末端重复环状未整合 HIV-1 DNA (2-LTR) 的存在是否与 HIV 疾病的加速相关。基线时 2-LTR 的检测与高血浆 HIV-1 RNA 水平 (p<. 01)、血浆中可培养 HIV-1 的恢复 (p=. 02) 以及随访期间进展为 AIDS (p=. 01) 相关。在随访的前 18 个月中,有 2-LTR 的患者 (68%) 比没有 2-LTR 的患者 (31%) 的 CD4 水平下降 > 50 个细胞/mm 3 更多 (p=. 04),有 2-LTR 的患者的年平均 CD4 下降率为 35%,而没有 2-LTR 的患者则为 16% (p= 0.06)。在基线时主要为非合胞体诱导 (NSI) 分离株的患者队列中,基线时 PBMC 中 2-LTR 的检测是高血浆 HIV-1 RNA 水平和随后的 CD4 细胞下降的独立预测因子。 PBMC 中 2-LTR 的存在似乎反映了正在进行的 HIV-1 复制(通过血浆 HIV-1 RNA 水平测量),并识别出处于免疫和临床衰退风险的人。
We observed 36 HIV-infected patients to evaluate whether the presence of tandem 2-long terminal repeat circular unintegrated HIV-1 DNA (2-LTR) in peripheral blood mononuclear cells (PBMC) at baseline was associated with acceleration of HIV disease. Detection of 2-LTR at baseline correlated with high plasma HIV-1 RNA levels (p<. 01), recovery of culturable HIV-1 from plasma (p=. 02), and progression to AIDS during follow-up (p=. 01). More patients with 2-LTR (68%) than without 2-LTR (31%) had a decline in CD4 levels of> 50 cells/mm 3 over the first 18 months of follow-up (p=. 04), and the average annual CD4 decline was 35% in patients with 2-LTR compared with 16% in those without 2-LTR (p= 0.06). Detection of 2-LTR in PBMC at baseline was an independent predictor of high plasma HIV-1 RNA levels and subsequent CD4 cell decline in this cohort of patients with predominantly nonsyncytium-inducing (NSI) isolates at baseline. The presence of 2-LTR in PBMC appears to be reflective of ongoing HIV-1 replication, as measured by plasma HIV-1 RNA levels, and identifies persons at risk for immunologic and clinical decline.
