Telomere length (TL) and immune activation markers were measured in a cohort of HIV-infected (n = 102) and age-matched non-HIV-infected (n = 41) men. TL was significantly shorter in HIV-infected compared with non-HIV-infected subjects (P = 0.04). Univariate analysis revealed a strong inverse relationship of TL to sCD163, and thus, monocyte/macrophage activation, among the HIV group (ρ = -0.30, P = 0.003). In multivariate modeling among the whole group, HIV-positive serostatus (P = 0.06) and sCD163 (P = 0.05) remained predictors of TL controlling for age and smoking status. Our data demonstrate that increased immune activation relates to shorter TL in HIV.
在一组感染HIV的男性(n = 102)和年龄匹配的未感染HIV的男性(n = 41)中测量了端粒长度(TL)和免疫激活标志物。与未感染HIV的受试者相比,感染HIV的受试者的TL显著更短(P = 0.04)。单因素分析显示,在HIV组中,TL与sCD163呈强烈负相关,因此与单核细胞/巨噬细胞激活呈负相关(ρ = -0.30,P = 0.003)。在整个组的多变量建模中,HIV阳性血清状态(P = 0.06)和sCD163(P = 0.05)仍然是控制年龄和吸烟状态后端粒长度的预测因素。我们的数据表明,免疫激活增加与HIV患者端粒长度缩短有关。
