Evaluation of Interferon-gamma Responses to HCMV Infection in HIV Positive Individuals

The study is designed to evaluate interferon responses to CMV in HIV positive individuals and a component will look at interferon responses to CMV in HIV positive individuals over time after commencement of antiretroviral therapy. We will also look at the correlation between CD4 T cell numbers and HLA type with the interferon response.
