AB Interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF-alpha) have
been implicated in the transition of nonreplicating latent human
immunodeficiency virus (HIV) infection to the replicating state of
productive infection. In HIV infection increased concentrations of these
cytokines in serum have also been found in association with
hypergammaglobulinemia. We have analyzed the ability of peripheral blood
mononuclear cells (PBMC) of HIV-infected children to secrete IL-6 and
TNF-alpha. In kinetic studies, optimum spontaneous IL-6 secretion by 1 x
10(6) PBMC was achieved at 24 hours. The mean spontaneous IL-6 and
TNF-alpha concentrations secreted by PBMC of known HIV-infected children
(age range, 8 months to 11 years) were 1686 and 131 pg/ml, respectively,
compared with 56 and 45 pg/ml, respectively, in normal healthy controls.
No significant correlation was observed between spontaneously secreted
IL-6 and TNF-alpha in culture supernatants with CD4 or CD8 numbers; with
serum IgG, IgA and IgM concentrations; or with lymphoproliferative
responses to recall antigens. There was, however, an association between
ability to secrete IL-6 with HIV-specific in vitro antibody production.
Spontaneous IL-6 secretion decreased transiently after initiation of
antiretroviral therapy, returning to original values with continued
treatment. Cytokine derangement in HIV-infected children includes
PBMC-derived spontaneous IL-6 and TNF-alpha secretion.
