AB These studies were undertaken to examine whether the presence of human
immunodeficiency virus type 1 (HIV-1)-neutralizing antibodies in sera of
infected individuals would alter the rate of disease progression.
HIV-1-infected individuals (n = 87) were initially examined for
neutralizing activity in vitro against both laboratory and tissue
culture-adapted clinical heterologous HIV-1 isolates. The neutralizing
activities of sera were determined by a 90% or greater reduction in
HIV-1 p24 levels in vitro. In a cross-sectional analysis of all infected
individuals, we observed that sera from asymptomatic individuals
neutralized a significantly greater number of heterologous HIV-1
isolates than sera from symptomatic patients. Patients who could be
followed up longitudinally (n = 24) were then studied to determine the
impact of neutralizing antibodies on the rate of disease progression. We
observed no significant difference between the numbers of HIV-1 isolates
neutralized in vitro by sera from patients who remained clinically
stable and by those from patients who progressed rapidly. Our data
indicated that the presence or absence of neutralizing antibodies to
heterologous HIV-1 isolates was not associated with the rate of disease
progression.
