Disseminated Kaposi's sarcoma in patients with HIV infection correlates to high serum levels of IL-10.

Abstract

Human herpesvirus 8 (HHV-8) is the etiologic agent of all Kaposi's sarcoma (KS), the outcome of which is associated with immuno-dysregulation, resulting in the abnormal production of inflammatory cytokines and chemokines. We quantified by enzyme-linked immunosorbent assay serum levels of interleukin (IL)-10, IL-17, interferon (IFN)-γ, and tumor necrosis factor (TNF)-α from patients with KS-AIDS, classic KS, and human immunodeficiency virus (HIV) without KS. A correlation between HHV-8 molecular detection and cytokine production was also performed. We observed that IL-10 production was higher in patients with KS-AIDS when compared to those with classic KS or HIV. However, no significant differences were seen for IFN-γ, TNF-α, or IL-17 production between studied groups. When patients with KS-AIDS were analyzed according to lesion topography, IL-10 levels were higher in patients with disseminated disease than those observed in patients with only cutaneous lesions or cutaneous and digestive and/or respiratory tract lesions. Finally, patients with KS-AIDS that presented viral DNA for HHV-8 in serum showed a higher production of IL-10 when compared with those patients with a negative result for nested polymerase chain reaction for the virus. The results presented here are the first to demonstrate that there exists a stratification of patients with KS-AIDS according to lesion topography where IL-10 levels are higher in those individuals with disseminated disease than those with only localized lesions.
