 AB    To define virologic and immunologic differences in patients with acute
       symptomatic and asymptomatic primary human immunodeficiency virus type 1
       (HIV-1) infection, sequential plasma specimens were obtained
       longitudinally for 1-2 years postseroconversion from subjects with
       well-documented time of seroconversion. Thirteen of them had an acute
       symptomatic primary infection, eight subjects had asymptomatic primary
       infection and long-term follow-up, and 27 had asymptomatic
       seroconversion and short-term follow-up. Quantitative plasma HIV-1 RNA
       levels, CD4+ lymphocyte counts, and levels of antibodies to gp120, p66,
       p41, p31, p24, and p17 were measured. At the time of seroconversion,
       there was no significant difference in HIV-1 RNA levels and CD4+ counts
       between symptomatic (n = 13) and asymptomatic (n = 27) subjects.
       Subsequently, however, establishment of low levels of plasma HIV-1 RNA
       was seen significantly more frequently in asymptomatic (n = 8) than in
       symptomatic (n = 13) primary infection; this correlated with higher
       levels of some (anti-gp120 and anti-p31) anti-HIV-1 antibodies and a
       slower decline in CD4+ lymphocyte counts. These results indicate that
       immunologic control of viremia early after infection may be a critical
       determinant to subsequent clinical course of HIV-1 infection. They also
       suggest that persons with acute symptomatic primary infection may
       generally progress to having acquired immune deficiency syndrome (AIDS)
       more rapidly than people with low-grade symptoms or asymptomatic primary
       infection.
