 AB    In 8 patients with symptomatic, acute primary infection with human
       immunodeficiency virus (HIV), a dramatic and persistent decrease in CD4+
       lymphocytes was seen, accompanied by a marked increase in
       activated/memory CD8+ T cells (CD38+, CD45R0+, HLA-DR+, with high
       amounts of cell adhesion molecules), which represented most circulating
       lymphocytes, but no gross alterations in V beta T cell repertoire.
       Extremely high plasma levels of proinflammatory cytokines were observed.
       Three patients were followed for 2-3 years: The number of CD4+ cells,
       extremely low at first, increased significantly in a few months but
       decreased rapidly after a short stable period. Cytotoxic T lymphocytes
       bearing markers of immunologic activation/memory could play an important
       role in the earliest phases of the disease. It remains to be established
       how such a dramatic onset could determine the rapid progression of the
       infection that seems characteristic of patients with acute HIV syndrome.
