Abstract

HIV-1 infection causes a severe T-cell impairment with alteration of immune response. However, in children the natural decline of lymphocytes and CD4 cells in early life makes it more difficult to monitor immunocompetence and progression of HIV-infection. Aim of this study was to characterize the CD8 response in non-vertically HIV-infected children exposed persistently to viremia and in HIV-infected children controlling efficiently viremia by ART, by analysing the effect of persistent viremia on CD4 and CD8 T-cells count, HIV-specific immune-response and naive/memory pattern of CD8 T-cell. Whereas, no differences of CD4 count between viremic patients and viral controllers were observed (1046.9±472.1 cells/pl vs 1101.3±415.4 cells/μl; p>0.05), CD8 count was higher in the viremic patients (1080.6±652.1 cells/pl vs 747.5±389.9 cells/pl, p
