AB HIV-1 infection and the HIV gp120 have been shown to induce an IL-10
increase in cultured peripheral blood mononuclear cells. Furthermore,
the expression of this cytokine has been reported to increase in
lymphnodes of infected patients along the disease course, and a shift
from the TH-1 towards the TH-0/TH-2 phenotypes (with subsequent IL-10
release) has been hypothesized to underly AIDS progression. In this
study the serum IL-10 levels found in 30 HIV-negative controls and in 65
HIV-positive patients, untreated with AZT and negative for HBsAg and
HCV-Ab have been compared, using a commercial, competitive ELISA method
based on a polyclonal anti-IL-10 serum. With this test, HIV-positive sea
showed IL-10 levels significantly higher than those found in the
controls. In addition the IL-10 levels progressively increased in the
subsequent CDC stages, without further changes from the stage III to the
stage IV. Accordingly, patients evaluated two times in CDC stage II,
with a time interval of at least one year, showed significant IL-10
increases, even more pronounced when the same patients passed from CDC
stage II to stage III. Furthermore, a significant, negative correlation
was observed between the circulating IL-10 levels and the patients'
CD4/CD8 ratios. These data may be important from a clinical point of
view since IL-10 monitoring could be considered as a surrogate marker
for evaluating the disease progression. In addition, several
immunological abnormalities present in HIV positive patients, such as
the monocyte/macrophage impairment and the hypergammaglobulinemia could
be related to the enhanced IL-10 expression.
