Pain in patients with HIV infection: issues for the new millennium

Pain is a common problem in people infected with the human immunodeficiency virus (HIV), particularly when they develop the acquired immune deficiency syndrome (AIDS). Until recently AIDS was a progressive fatal illness with a short prognosis, so the assessment and treatment of AIDS-related pain was logically based on the approach taken for the management of cancer pain. The cancer pain paradigm may no longer be appropriate for pain in patients with HIV infection, however, because the natural history of HIV disease has been transformed into a chronic illness by highly active anti-retroviral therapy (HAART), available since the late 1990s. In resource-poor countries of the Asia Pacific region where access to HAART is limited, the cancer pain paradigm may still be relevant. In this paper, the clinical characteristics of pain in HIV disease are described, along with current approaches to assessment and treatment. These are compared and contrasted with the characteristics, assessment and treatment of cancer pain. Data are presented which emphasize these similarities and differences, and highlight the need for a multidisciplinary, comprehensive approach to managing pain in HIV disease, now a chronic illness. There is a great need for more research on HIV-related pain in the HAART era. (C) 2001 European Federation of Chapters of the International Association for the Study of Pain.
