The effects of stressful life events, coping, and cortisol on HIV infection.

What is the role of stress and coping in changes in immunologic and clinical indicators of human immunodeficiency virus disease progression? There is substantial evidence that stressful life events and passive coping strategies, such as denial, may have a detrimental effect on HIV disease progression. Given the harmful effects of stress and passive coping, the author reviews the limited research testing the efficacy of interventions, such as cognitive-behavioral therapies for HIV-infected persons. Finally, in trying to understand psychoimmune relationships in HIV, the evidence is examined for the mediating and direct effects of cortisol, a hormone associated with stress, on HIV disease progression. Delineating the role of psychosocial factors and cortisol on HIV disease progression may aid in the development of new interventions for this devastating disease.
