AB 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 10-fold dilution
series of HIV-1-spiked plasma were correctly ranked by all six
procedures. Subsequently, coded duplicate plasma samples from 16
HIV-1-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-1 RNA levels
in the patients (up to 370,000 RNA copies/mL) correlated with proviral
HIV-1 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.
