Popis: The aim of this work was to analyze the effects of highly active antiretroviral therapy on the chronically activated immune system of 26 antiretroviral-naive HIV-1-infected patients. Samples from baseline to week 24 or 36 of treatment were tested for serum levels of beta2-microglobulin, tumor necrosis factor alpha and soluble tumor necrosis factor alpha receptor type II, as well as for human leukocyte antigen-DR expression on T cells. After starting therapy, the mean HIV-1 RNA serum levels decreased and the mean CD4 + cell counts increased from baseline to week 36 (P0.001). Mean levels of tumor necrosis factor alpha receptor type II, tumor necrosis factor alpha and beta2-microglobulin as well as expression of human leukocyte antigen-DR were significantly reduced at the end of follow-up (P0.01). Deactivation kinetics of these parameters was similar in patients with CD4+ counts200 cells/microl at baseline versus those with CD4 + counts200 cells/microl at baseline, despite higher activation at baseline in the group with200 cells/microl. In summary, this study shows that highly active antiretroviral therapy is able to induce a strong deactivation of the immune system of HIV-1-infected patients.
