Abstract:
Objective The plasma levels of interleukin 6 (IL-6),high sensitive C reactive protein (hs-CRP) and the level of T cell activation were detected in the peripheral blood inflammatory factors of acquired immunodeficiency syndrome (AIDS) patients,and the relationship with opportunistic infection and prognosis was analyzed.Methods 79 human immunodeficiency virus (HIV)-positive/aids cases from May 2014 to January 2015 in first hospital of Changsha were enrolled in the study.They were divided into three groups:HIV-infected without opportunistic infections group (n =20),HIV-infected with infections group (n =43,including HIV-infected with tuberculosis group,HIV-infected with merge fungus group.HIV combined hepatitis C),death group (n =16).Serum IL-6 and the concentration of hs-CRP were detected by enzyme-linked immunosorbent assay (ELISA).Flow cytometry was used to test the CD3 + CD4 + cell count,the percentage of CD4 + CD38 + cell and CD8 + CD38 + cell in peripheral blood mononuclear cell (PBMC).Compare the differences among the three groups.Results The results showed that:the concentration of hsCRP and IL-6 in peripheral blood of HIV death group was significantly higher than that in other three groups (P ＜ 0.05).The concentration of hs-CRP and IL-6 in the peripheral blood of the HIV-infected with tuberculosis group and HIV-infected with merge fungus group were significantly higher than that in the HIV-infected without opportunistic infections group (P ＜ 0.05),and the hs-CRP in the peripheral blood of the HIV combined with the hepatitis C group was higher than that in the HIV-infected without opportunistic infections group (P ＜ 0.05).The number of CD3,CD4T lymph nodes in the death group and the combined opportunistic infection group was significantly lower than that in the HIV-infected without opportunistic infections group (P ＜ 0.05).The HIV-RNA expression in peripheral blood of the death group and the combined opportunistic infection group was significantly lower than that in the HIV-infected without opportunistic infections group (P ＜ 0.05).The expression of CD8+CD38+ on PBMC in the HIV-infected without opportunistic infections group was significantly lower than that in the death group,the tuberculosis group,the fungus group and the hepatitis C group (P ＜ 0.05).The expression of CD4+ CD38 + on PBMC in the HIV-infected without opportunistic infections group was higher than that in the death group (P ＜ 0,05).Conclusions The concentration of inflammatory cytokines (IL-6,hs-CRP) and the expression level of T cell surface CD8 + CD38 + related to immune activation were associated with opportunistic infection and prognosis of AIDS.
