Unique Identifier : AIDSLINE ICA10/94369794 AB A randomized double-blind controlled trial was conducted to determine the long term efficacy of passive immunotherapy (PI) in the treatment of symptomatic HIV infection. This prospective trial (IPOO2) included symptomatic patients randomized in 2 groups. One group received plasma rich in anti-p24 antibody (HIV+P), the other received standard seronegative plasma (HIV- P). Each patient in both groups received a 300 mL infusion every 14 days over a one-year period, in addition to zidovudine and other prophylactic treatments. To obtain HIV+P, donors were selected among symptomless anti-HIV+ individuals with a CD4 count > or = 400 and a high concentration of anti-p24 antibody. The plasmas were heated before infusion. Upon the advice of the independent committee, the inclusion of new patients ceased in July 1993. At this time, 86 patients had been included. A significant difference was observed between both groups in the delay of appearance of the onset of the first AIDS defining event (p < 0.009) and in the cumulative number of events (p < 0.0008) over the study period of one-year; 18 deaths occurred within the study period, 7 in the treated group and 11 in the controls (p = .27). The number of days of hospitalisation was 679 in the treated group and 1379 in the control group. Infusions of HIV+P every two weeks may favorably modulate the natural history of infection and improve the quality of life of AIDS patients.
