[THE IMMUNOMODULATORY ACTIVITY OF PLASMA OF PATIENTS INFECTED WITH HUMAN HIV VIRUS]

The study was carried out to investigate impact of plasma of patients infected with human HIV virus receiving and not receiving highly active antiviral therapy on: expression of phenotypic markers of lymphocytes (CD3+, CD3+/CD4+, CD3+/CD8+, CD19+, CD3-/CD (16+56)+, CD3+/CD(16+56)+, CD3+/HLA-DR+, CD4+/CD62L+, CD8+/CD38+) in mononuclear cells of blood of donors and secretion of pro-inflammatory (interleukin-1β, interferon-γ, tumor necrosis factor-α, interleukin-4 and interleukin-10) cytokines. After 24 hours of activation of mononuclear cells with plasmas it was demonstrated that as compared with control groups, in of plasmas of patients with highly active antiviral therapy increasing of number of CD4+ T-cells and decreasing of CD8+ T-cells is observed. The plasmas of patients with highly active antiviral therapy activate in most instances CD4+ T-cells whereas plasmas of patients without treatment--CD8+ T-cells. The results of detection of cytokines in blood indicate that in patients without treatment inflammatory potential is increased as compared with group of highly active antiviral therapy. The data concerning accumulation of interleukin-1β under cultivation of mononuclear cells with plasmas indicates at its role in preservation of vitality of natural killers. The analysis of immunomodulatory activity of plasma of patients infected with human HIV virus can be recommended as an additional technique of evaluation of functioning of immune system.
