Abstract
- <bold>Objective: </bold>To explore the association between infections with HIV and Schistosoma japonicum, and to determine the influences of the HIV-S. japonicum coinfections on the immune system of Yi people.<bold>Methods: </bold>A block design study was conducted in a Yi county in southwestern China, one of the endemic areas of both HIV/AIDS and S. japonicum in China. All participants were screened for HIV antibodies and S. japonicum antibodies (SjAb) and were classified into four groups: HIV(+)/S. japonicum(-), HIV(-)/S. japonicum (+), HIV(+)/S. japonicum(+), and HIV(-)/S. japonicum(-).<bold>Results: </bold>There were significant differences among the four groups in both CD4+ T lymphocytes and CD8+ T lymphocytes, but no significant difference in CD3+ T lymphocytes. Both the CD4+ T lymphocyte counts and the ratio of CD4+/CD8+ were lower in HIV-infected people compared with those uninfected. People infected with S. japonicum had increased CD4+ T lymphocyte counts but reduced CD8+ T lymphocyte counts. Similarly, the ratio of CD4+/CD8+ was higher in S. japonicum-infected people compared with those uninfected. People coinfected with HIV and S. japonicum had lower CD4+ T lymphocyte counts, lower ratio of CD4+/CD8+, and higher CD8+ T lymphocyte counts compared with those infected with HIV only or S. japonicum only. People infected with HIV only and those coinfected with HIV and S. japonicum had a higher level of IFN-γ compared with people with no infection. There were no significant differences between people infected with HIV only and with S. japonicum only in the levels of IFN-γ and IL-10.<bold>Conclusions: </bold>People coinfected with HIV and S. japonicum might have a suppressed immune function because of a decrease in CD4+ T lymphocyte counts, a lowered ratio of CD4+/CD8+, and an increase in CD8+ T lymphocyte counts. Coinfection with HIV and S. japonicum would alter the level of IFN-γ in plasma. [ABSTRACT FROM AUTHOR]
