Abstract

We studied the effect of hepatitis C virus coinfection on T cell subpopulations in HIV-infected patients receiving antiretroviral therapy. Coinfection with hepatitis C virus was followed by a decrease in the number of naive CD4(+) T cells and an increase in the count of central CD8(+) memory T cells in these patients. Hepatitis C virus had no effect on the number of CD4(+) memory T cells (main target for HIV). This can explain the absence of strong negative effect of hepatitis C virus on the course of HIV infection.

Keywords: HCV coinfection; HIV infection; T cell subpopulations; antiretroviral therapy.
