ABSTRACT
Imbalance in the immune response is one of the main pathogenic mechanisms of diseases related with human immunodeficiency virus (HIV)/human gammaherpesvirus 8 (HHV-8) coinfection, such as Kaposi's sarcoma (KS), primary effusion lymphoma (PEL), multicentric Castleman disease (MCD) and the Kaposi's sarcoma-associated herpesvirus inflammatory cytokine syndrome (KICS). However, significant changes in pro- and anti-inflammatory cytokine levels may be observed in HIV/HHV-8 individuals who are negative for KS, PEL, MCD, and/or KICS. In this study, serum levels of interleukin-2 (IL-2), IL-4, IL-6, IL-10, tumor nucrosis factor α (TNF-α) and interferon γ (IFN-γ) were assessed in 69 HIV and 48 HIV/HHV-8 individuals, all negatives for HHV-8-related diseases. The cytokines were measured by flow cytometry and analyzed by the Mann-Whitney test. The p < .05 and 95% confidence interval were considered in all analyzes. IL-4 (p = .0155), IL-6 (p = .0036), and IL-10 (p = .0036) levels were significantly higher in HIV/HHV-8 patients than in the HIV group. On the other hand, IL-2 (p = .2295), TNF-α (p = .1216) and IFN-γ (p = .1178) did not differ between the groups analyzed. To our knowledge, to date, this is the first report on significant differences in the levels of IL-4 and IL-6 in HIV versus HIV/HHV-8 individuals. Finally, these early findings are important as a prognostic tool and contribute to clarifying the HHV-8-host interaction.
