Correlates of progression of human immunodeficiency virus (HIV) infection to AIDS include the reduction in CD4+ T cells and the emergence of syncytium-inducing (SI) HIV variants. It has been suggested that progressive defects in interleukin 2 (IL-2), IL-12, and IFN- gamma production (type 1 cytokines), and increased production of IL-4 (and of IL-4-driven hyper-IgE), IL-6, and IL-10 (type 2 cytokines), could provide another correlate of disease progression.

In addition, we observed that the isolation of HIV SI and the production of high quantities of type 2 cytokines are correlated with increased loss of CD4 T cells in the 12 months preceding the determinations.

Abstract

Correlates of progression of human immunodeficiency virus (HIV) infection to AIDS include the reduction in CD4+ T cells and the emergence of syncytium-inducing (SI) HIV variants. It has been suggested that progressive defects in interleukin 2 (IL-2), IL-12, and IFN- gamma production (type 1 cytokines), and increased production of IL-4 (and of IL-4-driven hyper-IgE), IL-6, and IL-10 (type 2 cytokines), could provide another correlate of disease progression. To determine the possible association among these markers, viral phenotype, cytokine production, IgE serum concentration, and rate of CD4 depletion were analyzed in a cohort of vertically HIV-infected children. We report that significantly higher production of type 2 cytokines and augmented IgE concentration are observed in children in whom HIV SI is isolated. In addition, we observed that the isolation of HIV SI and the production of high quantities of type 2 cytokines are correlated with increased loss of CD4 T cells in the 12 months preceding the determinations. These data suggest that the virologic and immunologic parameters characteristic of advanced HIV infection may be associated in pediatric HIV infection, and indicate a virologic-immunologic pathogenesis leading to the appearance of AIDS.
