Spontaneous in vitro anti-human immunodeficiency virus type 1 antibody secretion by peripheral blood mononuclear cells is related to disease progression in zidovudine-treated adults.
As part of a continuous search for surrogate markers of therapeutic efficacy in AIDS, spontaneous in vitro production by peripheral blood mononuclear cells of antibody to human immunodeficiency virus type 1 (HIV-1) was investigated in 50 HIV-1-infected adults. It was independent of CD4+ cell counts, p24 antigenemia, serum beta 2-microglobulin concentration, and clinical status of the patients. The effect of zidovudine on this antibody secretion and the appearance of signs or symptoms of HIV-1 disease progression were evaluated in 20 patients over 24 weeks. Anti-HIV-1 antibody secretion decreased significantly (P = .002) as of the first month of zidovudine treatment only in the 13 HIV-1-infected patients without disease progression. This is earlier than the occurrence of variations in CD4+ cell count and serum beta 2-microglobulin concentration. These results suggest that in vitro antibody production could be a surrogate marker for evaluation of the in vivo antiretroviral efficacy of zidovudine, even in p24 antigen-negative patients.
