Herpes simplex type 1 encephalitis in acquired immunodeficiency syndrome.

ABSTRACT

A severe acute necrotizing herpes simplex virus type 1 encephalitis, apparently mediated by macrophages or cytokines or both, was seen in a patient with acquired immunodeficiency syndrome. The necrosis had a distribution similar to that seen in immunocompetent subjects. Viral inclusions were abundant and meningeal reaction was minimal, as previously described in one anergic patient.
