 AB    We directly observed 31 API and 168 asymptomatic seroconversions (AS) in
       patients (pts) who were seronegative in the previous 12 months. API was
       more frequently seen in pts who had HIV-1 through sex (chi 2 = 29.1; p =
       .00000). Api clinical aspects ranged from flu-like syndrome to
       mononucleosis-like syndrome. Two pts had a polyneuropathy and 2 a
       meningitis. At onset, all the pts were anti-HIV-1Ab (ELISA) negative and
       27/32 had serum p24Ag. Serum p24Ag was found after immune complex
       dissociation in the other pts. CD4+/CD8+ ratio was low in most pts
       because of CD8+ increase, whereas CD4+ were slightly low. NK were also
       increased. Seroconversion with ELISA occurred in a mean time of 41.7 +/-
       15.3 days. HIV-1 with rapid-high syncytium inducing phenotype was
       isolated in 4/7 pts. At the onset, in 15 pts IL-2 serum levels was low,
       soluble CD8 antigen, IL-1 beta, IFN-gamma and 5'-neopterin were
       increased. Follow-up showed significant decrease of IL-1 beta levels and
       increase of IL-6. API pts resulted significantly at higher risk of
       developing AIDS than AS (43% vs 7% at 45 months; p = .00001). On the
       basis of our results the early administration of antiviral drugs and
       IL-2 is of interest.
