The Immunotherapy of HIV Infection with Drugs

  • John W. Hadden

Abstract

The history of the effort to treat HIV infection with immunotherapeutic drugs has been a frustrating one. Soon after the onset of this epidemic in 1981, there were extensive efforts to use a long list of drugs being employed in cancer immunotherapy to treat AIDS. As predicted (Hadden, 1985), these attempts failed (Hadden, 1991; Specter and Hadden, 1992). The problem, quite simply, related to the predicted inability of any drug to increase T-cell number by any mechanism other than the inhibition of HIV replication. In approaching this discussion, I recognize that this topic is not in vogue. In fact, in some recent reviews, the subject of immunotherapeutic drugs is not even mentioned (Laurence, 1995; Lederman, 1995). I take a different view (Hadden, 1991). I would contend that the efforts using some of the drugs have taught that not only are they safe but also that they can reduce the development of AIDS-defining clinical events and can often delay the predicted decline in CD4 T lymphocytes. Nevertheless, the efforts have not demonstrated a convincing mechanism of action. The problem remains to be properly phrased: What can immunotherapeutic drugs be expected to do for HIV infection? and How do we measure the effect by other than clinical endpoints?, i. e., how can we prove the mechanism of action? It will be the purpose of this chapter to review the progress of efforts to employ such drugs in HIV infection prior to the development of AIDS and to delineate prospects for better defining and improving such treatment.
