AB Non-Hodgkin's (1ii)lymphoma is an AIDS-defining event in a significant
percent of U.S. patients infected with the human immunodeficiency virus
(HIV). Advances in anti-retroviral treatment and management of
opportunistic infection have been accompanied by an increase in the
incidence of these lymphomas. In the immunocompromised state of patients
late in the course of HIV infection, these lymphomas represent a
complication of HIV infection that is associated with an extremely poor
prognosis. Currently, there is little understanding of the pathogenesis
of HIV-associated lymphomas, which are nearly exclusively of B-cell
origin. Experimental data do not support HIV infection in these
lymphomas. While some lymphomas show evidence of EBV infection, the
majority do not. Polyclonal B-cell hyperactivity during the early phases
of HIV infection argues that chronic B-cell stimulation may be the major
process predisposing B-cells in the HIV-infected individual to malignant
transformation. The mechanism of this stimulation of normal B cells and
its relationship to AIDS-associated lymphomas remain poorly understood.
In this review, we will summarize current information on HIV-associated
B lymphoma and then discuss our views on the association and regulation
of HIV-related hyperactivity on the pathogenesis of this lymphoma.
