Reduced neutrophil production of leukotriene B4 associated with AIDS

AIDS. 1989 Oct;3(10):651-3. doi: 10.1097/00002030-198910000-00006.

Abstract

Neutrophils from 10 homosexual men with evidence of HIV infection and 10 healthy controls were tested for their capacity to generate leukotriene B4. Neutrophils from patients with AIDS produced less leukotriene immunoreactivity when appropriately stimulated than neutrophils from healthy controls, whereas no significant difference could be detected between HIV-antibody-positive individuals without AIDS and healthy controls. This observation may be pertinent to the recurrence of some of the opportunistic infections associated with AIDS but more importantly, if reflecting a general defect in leukotriene production, it may provide further understanding of the mechanism which leads to reduced natural killer-cell activity, interleukin-2 and interferon-gamma production in AIDS.
