Antibodies (Ab) that induce antibody-dependent cell-mediated cytotoxicity (ADCC) against non-T lymphocytes, anti-HLA class II specific Ab and anti-PMN were tested in hemophilic (He) patients who were alloimmunized because they had received replacement treatment with blood derivates and become infected with HIV, as well as in those who remained seronegative. In addition, the serum reactivity of spouses of HIV+ individuals and their children was studied to determine the effect of HIV infection in the absence of concomitant alloimmunization. The results of this study indicate that ADCC Ab were already present in HIV- He, suggesting the influence of alloimmunization. Their titer increased after appearance of HIV disease. While low reactivity against class II antigens was observed in HIV- He, activity augmented sharply after HIV infection and increased further with disease progression. Anti-PMN reactivity followed a similar pattern. Anti-class II, ADCC Ab and anti-PMN were also detected in the asymptomatic HIV+ spouses of HIV+ patients in titers that were similar to those of asymptomatic HIV+ He. In children born to HIV+ mothers in whom HIV infection was confirmed, anti-class II, ADCC Ab and anti-PMN reactivity were also observed, and activity increased after the onset of disease. These results suggest that induction of anti-leukocyte Ab occurs in the absence of massive allostimulation after HIV infection. HIV infection may enhance preexisting class II and anti-leukocyte response in allostimulated individuals.
