Abstract
The relationship between immunity disorders, destruction of intestinal barrier and development of systemic inflammation during antiviral therapy in patients with HIV infection is a topical issue in terms of suppression of virus replication and reduction of its role in the pathological process. Blood of HIV-infected patients given antiretroviral therapy (n = 21) and non-infected volunteers (n = 20). Identification of cells among CD4⁺ and CD8⁺ T-lymphocytes expressing markers of activation (CD38, HLA-DR), depletion (PD-1), and interleukin (IL) 7 receptor (CD127); measurement of blood levels of IL-6, neopterin, soluble CD14 (sCD14), intestinal fatty acid-binding peptide (I-FABP), and bacterial lipopolysaccharide. Correlation analysis of the dependence between cell immunity and systemic inflammation was performed. HIV-infected patients had more activated CD4⁺ and CD8⁺ T-lymphocytes and CD4⁺ T-cells expressing PD-1 marker than non-infected subjects but less CD4⁺ and CD8+ T-lymphocytes expressing CD127. Blood IL-6, neopterin, soluble CD14, I-FABP and bacterial lipopolysaccharide levels in the former were higher than in the latter HIV-infected patients showed significant correlation of cell immunity parameters with blood neopterin and FABP levels. The process of activation, depletion, and regeneration of T-lymphocytes in. HIV infection are related to the destruction of intestinal barrier and systemic macrophage activation.
