- 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.
