 AB    The relationship between cell-associated infectious human
       immunodeficiency virus type 1 (HIV) load (infectious units/10(6)
       peripheral blood mononuclear cells [IUPM]) and phenotypes of CD4+ and
       CD8+ lymphocytes was studied. IUPM were measured in 242 HIV-infected
       homosexual men by quantitative microculture and T cell subsets by
       two-color flow cytometry. In multivariate analysis, IUPM correlated
       negatively with CD4+ lymphocyte level and with a diagnosis of AIDS and
       positively with the proportion of CD8+ lymphocytes expressing the
       activation marker CD38. After adjusting for level of CD4+ lymphocytes,
       men with AIDS had significantly lower IUPM than those without AIDS. The
       correlation between IUPM and CD4+ lymphocyte level was largely explained
       by correlation with level of CD4+ lymphocytes with resting phenotypes
       (HLA-DR-, CD38-) rather than with those expressing HLA-DR and CD38.
       Thus, subsets of CD4+ lymphocytes may vary in cell-associated infectious
       HIV content at different stages of HIV infection.
