Enterovirus associated neurological disease in an HIV-1 infected man

We report a case of relapsing multifocal neurological disease associated with CNS echovirus 6 infection in an HIV-1-infected individual with no evidence of immunoglobulin deficiency, The illness was initially characterized by optic and cranial neuropathies and myelopathy; concurrent granulomatous hepatitis suggested disseminated viral infection. Treatment with combination nucleoside analogues led to partial remission, but a demyelinating polyneuropathy subsequently developed, There was improvement and sustained remission in the polyneuropathy following treatment with intravenous immunoglobulin. Neurotropic enterovirus infection may be involved in the pathogenesis of certain HIV-associated neurological syndromes.
