Dysfunction of the central nervous system (CNS) is a prominent feature of the acquired immune deficiency syndrome (AIDS). Many of these patients have a subacute encephalitis consistent with a viral infection of the CNS. We studied the brains of 12 AIDS patients using in situ hybridization to identify human immunodeficiency virus [HIV, referred to by others(More)
Monocytes are one of the predominant cell types in the peripheral blood that are infected by human cytomegalovirus (HCMV). Although virus can be detected in these cells in vivo, HCMV replication in cultured monocytes has been unsuccessful. In this study, we demonstrate efficient HCMV replication in cultured monocytes. HCMV permissiveness in these cells was(More)
BACKGROUND Host genetic factors are important determinants for risk of HIV-1 infection and disease progression. This study examined associations of host genetic variants and neurocognitive impairment in Chinese individuals infected through contaminated blood products. METHODS Two hundred and one HIV-infected patients from Anhui, China, had(More)
Approximately one-half of autopsied acquired immune deficiency syndrome (AIDS) patients demonstrate probable human cytomegalovirus (CMV) infection of the central nervous system (CNS). Because CMV in brain tissue or cerebrospinal fluid is difficult to culture, we used antisera, and radioactive probes to diagnose CMV infection in the brain of an autopsied(More)
PURPOSE To investigate immune and viral contributions to the pathogenesis of immune recovery uveitis (IRU), which presents as vitritis, macular edema, or formation of epiretinal membranes, and develops in patients with acquired immunodeficiency syndrome (AIDS) who experienced cytomegalovirus (CMV) retinitis before antiretroviral treatment (ART) induced(More)
To characterize the influence of highly active antiretroviral therapy (HAART) on cell-mediated immunity (CMI) to Mycobacterium avium complex (MAC), we measured immune responses to M. avium in human immunodeficiency virus (HIV)-infected individuals before and during HAART, in subjects with a history of disseminated MAC (DMAC), and in HIV-uninfected control(More)
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(More)
BACKGROUND HIV associated neurocognitive disorders (HAND) continue to affect cognition and everyday functioning despite anti-retroviral treatment (ART). Previous studies focused on mechanisms related to monocyte/macrophage mediated inflammation. However, in the ART era, there is increasing evidence for the involvement of CD8+ T-cells in CNS pathogenesis. (More)
To investigate the association of antigen specific CD4 T cell activation with HIV disease progression and AIDS-related central nervous system damage, T cell proliferation responses to HIV, CMV, and HSV were evaluated in infected individuals. CD4 T cell loss and neurocognitive impairment were assessed at 6-mo intervals. Individuals with known times of(More)
CMV retinitis develops in 28-35% of all AIDS patients at later stages of disease, often leading to blindness. To determine whether the subset of AIDS patients who developed CMV retinitis (CMV-R) were immunologically predisposed, T cell proliferation responses to CMV were examined prospectively in an HIV infected, HLA typed, longitudinal study population.(More)
