AB Changes in viral load have been reported to reflect disease progression
or response to therapy; however, the stability of HIV DNA levels in
HIV-infected individuals has not been extensively studied. Cellular HIV
DNA levels in infected individuals were evaluated over a short time
period to determine degree of variability as well as any correlation
with other measurements of virus load or immune status. Peripheral blood
mononuclear cells (PBMC) were obtained several times over 1 month from
32 asymptomatic or symptomatic non-AIDS, HIV-infected individuals
currently on AZT therapy. PCR amplification of the HIV gag region was
performed with DNA from PBMC lysates and the PCR amplified products
quantitated by liquid phase hybridization. HIV DNA levels in the
majority of the patients were relatively stable, with 26 of 32 persons
having less than threefold change. Changes over the study period were
both positive and negative, and the median change in HIV DNA levels was
68.6%. These changes were found to positively correlate with
fluctuations in plasma p24 levels. In contrast, no correlations were
found with other measurements of immune system activity, including
changes in CD4 number, CD4 percent, and beta 2-microglobulin when
compared with provirus changes. This study shows that levels of HIV DNA
can be relatively stable over short periods in most non-AIDS,
HIV-infected persons.
