disorders

The human T-lymphotropic virus type III (HTLV-III) is the primary cause of
the acquired immunodeficiency syndrome (AIDS) and related disorders (ARC).
Prior studies have reported that nearly all symptomatic patients with AIDS
or ARC manifest antibody to HTLV-III. This observation has engendered
efforts to screen for HTLV-III, especially prior to blood donation, with
assays for antibody to HTLV-III. We report the first two cases, one with
AIDS and one with ARC, that are HTLV-III virus positive but antibody
negative. Accurate diagnosis of HTLV-III infection in some cases may
require direct virus culture or tests for antigen. In addition, lack of
HTLV-III antibody may indicate an atypical clinical course of AIDS.
