Zusammenfassung:Kaposi's sarcoma-associated herpesvirus (KSHV) specific T cell responses and KSHV viremia were analyzed in seven HIV-infected patients with active Kaposi's sarcoma lesions who initiated highly active antiretroviral therapy, and were compared between patients with improved Kaposi's sarcoma and those with progressive Kaposi's sarcoma requiring further systemic chemotherapy. Patients with controlled Kaposi's sarcoma disease demonstrated undetectable Kaposi's sarcoma viremia together with KSHV-specific CD8 T cells secreting interferon-gamma and tumor necrosis factor-alpha, whereas progressors showed increasing viremia with weak or no T-cell responses. These data point toward a potential role of KSHV-specific immunity in the control of AIDS-associated Kaposi's sarcoma.
