title: Neutralizing antibody responses in patients with AIDS with neurologic complications.
abstract: Although the human immunodeficiency virus type 1 (HIV-1) is frequently isolated from the cerebrospinal fluid of infected patients, only a small percentage of patients are found to have clinical dementia or neuropathies (or both). The reasons for this remain unclear. In our study, serum neutralizing antibody titers against the human T cell leukemia virus-IIIB isolate of HIV-1 were tested in 10 patients with acquired immunodeficiency syndrome (AIDS) with neurologic complications and 20 patients with HIV infection without neurologic complications. Titers were significantly lower in the neuro-AIDS group, suggesting that impaired neutralizing antibody responses in this subpopulation of patients may be involved in the immunopathogenesis of AIDS encephalopathy.
