九个实验室对 6 种血浆人类免疫缺陷病毒 1 型 (HIV-1) RNA 定量程序进行了评估。这些程序的不同之处在于样品体积、样品制备以及扩增和检测方法。 HIV-L 加标血浆的 IO 倍稀释系列中的编码样本通过所有六种程序均被正确排序。随后,使用一套通用标准对来自 16 名 HIV-1 感染患者的编码重复血浆样本进行了测试。几个 HIV-1 RNA 程序具有足够的可重复性,因此经验性的 4 倍变化可以被视为显着。患者中的HIV-1 RNA水平(高达370,000 RNA拷贝/mL)与前病毒HIV-1 DNA相关,并且与CD4细胞计数呈负相关; HIV-1 RNA 检测比血浆病毒血症、标准 p24 抗原或免疫复合物解离的 p24 抗原检测更敏感。这项研究表明,几种 HIV-1 RNA 定量测定方法已准备好用于临床试验。
Six procedures for quantifying plasma human immunodeficiency virus type 1 (HIV-1) RNA were evaluated by nine laboratories. The procedures differed in their sample volume and preparation of samples and methods of amplification and detection. Coded samples in a IO-folddilution series of HIV-L-spiked plasma were correctly ranked by all six procedures. Subsequently, coded duplicate plasma samples from 16 HIV-I-infected patients were tested using a common set of standards. Several HIV-1 RNA procedures were sufficiently reproducible so that an empiric 4-fold change could be viewed as significant. HIV-I RNA levels in the patients (up to 370,000 RNA copiesjmL) correlated with proviral HIV-I DNA and were inversely correlated with CD4 cell counts; HIV-1 RNA assays were more sensitive than plasma viremia, standard p24 antigen, or immune complex-dissociated p24 antigen assays. This study demonstrated that several HIV-1 RNA quantitative assays are ready for use in clinical trials.
