AB During the symposium on surrogate markers of HIV, the Scientific
Advisory Committee posed the following question: Which surrogate markers
currently deserve the greatest commitment of investigative resources to
validate them in a clinical setting? The Committee concluded that for
antiretroviral drugs measurements of HIV RNA in plasma deserve the
greatest priority, and for immune-based therapies assessing viral load
still had the highest priority. But it was recognized that assessing
viral load should not be restricted to plasma RNA because the primary
mechanisms of action are different from antiretroviral drugs. Thus, the
Committee voted that based on current knowledge, investigating the
clinical relevance of changes in HIV-1 DNA and RNA copy number in
peripheral blood mononuclear cells (PBMCs) with validated assays should
be given equal focus for immune-based therapies. This article reviews
the rationale for using HIV-1 DNA and RNA load in PBMCs for the
monitoring of clinical trials and presents recent data that indicate
that the postseroconversion level and the dissemination of proviral DNA
in the blood cells have prognostic value, i.e., high levels correlate
with disease progression. In addition, longitudinal studies show that an
increase in proviral DNA and/or HIV mRNA load correlates with disease
progression. We present evidence that these markers are relevant
activity markers for anti-HIV therapies. Changes in both DNA and RNA
load can be achieved using either antiretroviral drugs or immune-based
therapies. These results suggest that these markers should be evaluated
in clinical studies to firmly establish their value as surrogates of
clinical progression.
