Abstract

To gain insight into determinants that define the duration of the asymptomatic period preceding AIDS, groups of long-term asymptomatic (LTA) person (> 7 years of follow-up) and slow and rapid progressors of human immunodeficiency virus infection were studied. LTAs had no clinical manifestations of AIDS or immunologic abnormalities in 7 years of follow-up. RNA copy numbers, gag- and env-specific, and neutralizing antibody titers in serum were determined 1 and 5 years after seroconversion or entry into the cohort. Early in infection, before immunologic markers or clinical manifestations allowed group discrimination, subjects who were later classified as LTAs had significantly less serum viral RNA than progressors. No significant increase in virus load was found in progressors, indicating that the initial load defines clinical outcome. In slow progressors, high virus load was associated with high p24-specific antibody titers, suggesting that delay of clinical manifestations of AIDS may be related to the presence of high levels of p24-specific but not V3-specific antibodies
