Abstract: In order to determine whether there exists a distinct immunological profile that discriminates between healthy homosexual men and those expressing persistent generalized hyperplastic lympadenopathy GHL and which of the observed abnormalities in GHL would be most indicative of patients who would eventually develop AIDS, we evaluated T lymphocyte subset and in vitro proliferative responses. The respective profiles of 44 symptom free homosexual men (HC), 42 patients with GHL and 30 cases of AIDS were compared to that of blood bank volunteers (BBV) and to each other, using stepwise discrimination analysis. HC, GHL and AIDS patients demonstrated upon their first investigation varying degrees of the same type of abnormal immunological characteristics. The percentage of OKT4+ cells was the most discriminant variable between BBV and HC, GHL or AIDS. GHL was distinguished from HC primarily by a higher percentage of OKT8+ cells and from AIDS by higher T lymphocyte counts, while the OKT4+ cell count discriminated between AIDS and HC. However, none of these major discriminant variables could classify correctly more than 71% within the HC and the two patient groups. Thus, there exists a continuity between GHL and AIDS in the range of observed immunological abnormalities without clearcut boundaries. This, together with the existence of abnormal background values in HC will not permit a single investigation of T lymphocyte immune parameters to provide substantial diagnostic and prognostic evidence.
