本文对血清β2-微球蛋白、新喋呤、免疫球蛋白A、G、M、腺苷脱氨酶和CD_4 ~+淋巴细胞计数等指标进行了评价,以作为HIV-1感染进展为AIDS的预测指标。对HIV-1血清阳性、最初无症状的男性(n=213)和女性(n=101)人群进行了季度随访。我们使用精算方法估计无艾滋病时间(中位生存时间47.2个月)。考克斯比例风险分析显示,所有研究的标志物与进展为AIDS相关均具有显著性(p<0.05)。预测AIDS进展的最佳指标依次为CD 4+淋巴细胞计数、β2-微球蛋白、伊加、新喋呤、IgG、IgM和腺苷脱氨酶。在将群体分层为四组(在第25、50和75个等级处划分-从具有最接近参考范围的值的第1组到具有最异常值的第4组)时,我们观察到除腺苷脱氨酶之外的所有标记物的统计学显著差异(p<0.05)。使用来自考克斯比例风险模型的相对风险来量化最佳标志物的效果,并与第1组中获得的风险进行比较。CD 4+淋巴细胞计数是进展为AIDS的最佳预测因子。当同时考虑β2-微球蛋白和CD 4+时,CD 4+细胞计数最低组(第4组)的相对风险范围为25. 6%(β2-微球蛋白值较低)至41. 1%(β2-微球蛋白值较高)。当同时考虑新蝶呤和CD 4+时,获得了类似的结果。在CD 4+淋巴细胞计数中加入β2-微球蛋白或新喋呤值可提高CD 4+淋巴细胞计数的预测价值。
Abstract Serum β2-microglobulin, neopterin, immunoglobulins A, G and M, adenosine deaminase and CD4+ lymphocyte count were evaluated as predictors of progression of HIV-1 infection to AIDS. A population of HIV-1 seropositive, initially asymptomatic men (n=213) and women (n=101) was followed up quarterly. We estimated the AIDS-free time using the actuarial method (median survival time 47.2 months). Cox proportional hazard analysis revealed that all markers studied were significant (p<0.05) in relation to progression to AIDS. The best markers for predicting progression to AIDS were, in descending order, CD4+ lymphocyte count, β2-microglobulin, IgA, neopterin, IgG, IgM and adenosine deaminase. On stratifying population into four groups (devided at percentiles 25, 50 and 75—from group 1, with values nearest to reference ranges, to group 4, with most abnormal values) we observed statistically significant differences (p<0.05) for all markers except for adenosine deaminase. The relative risk from the Cox proportional hazards model were used to quantify the effects of the best markers and compared to the risk obtained in group 1. CD4+ lymphocyte count was the best predictor of progression to AIDS. When considering β2-microglobulin and CD4+ together, the relative risk in the group with lowest CD4+ cell count (group 4) ranged from 25.6% (with lower β2-microglobulin values) to 41.1% (with higher β2-microglobulin values). Similar results were obtained when considering neopterin and CD4+ together. The addition of β2-microglobulin or neopterin values to CD4+ lymphocyte count improved the predictive value of CD4+ lymphocyte count.
