Abstract
Behavioral factors may have an effect on the course of infection in HIV-1 infected individuals. These effects can be mediated by the immune system of the host, which, based on psychoneuroimmunologic findings, can be affected by some psychosocial factors. We present a short review of some putative psychoneuroimmunologic pathways and their possible implications for HIV-1 infected individuals. We next summarize the findings of recent psychoimmunological work with HIV-1 seropositives and discuss the methodological problems in studying the psychoneuroimmunologic aspects of HIV-1 infection. Psychoneuroimmunologic research in HIV-1 seropositives is a rapidly developing field, yielding contradictory findings so far, but which in the long run could provide important knowledge for psychoimmunologic interventions, targeted at improving or preserving immune status and retarding disease progression, as well as optimizing psychosocial functioning.
