Abstrakt: To better understand the relation of cytomegalovirus (CMV)-specific CD4+ T lymphocyte immunity and clinical outcome in AIDS-related CMV end-organ disease, 2 patient groups were prospectively studied: patients recently diagnosed with active CMV end-organ disease and survivors of CMV retinitis who had responded to highly active antiretroviral therapy and had quiescent retinitis when anti-CMV therapy was discontinued. Most patients with active CMV disease had negative CMV-specific CD4+ T lymphocyte responses at diagnosis, as measured by lymphoproliferation (7/7) or cytokine flow cytometry (3/5) assays. In contrast, all 10 subjects with quiescent retinitis and >150 absolute CD4+ T lymphocytes/microL whose anti-CMV therapy was discontinued during 6 months of follow-up had positive CMV-specific immune responses at least once by each assay. However, 6 of these 10 subjects also had negative CMV-specific immune responses > or =1 time. Such patients may be at risk for future CMV disease progression and should be closely monitored.
