Articular manifestations of human immunodeficiency virus infection.

Prospective studies of HIV-positive and HIV-negative individuals, longitudinal prospective studies of HIV-positive patients and the African experience with spondyloarthropathies have provided support for a direct role of HIV infection in producing a variety of articular manifestations. The most common manifestations are arthralgia and the spectrum of spondyloarthropathies, but distinct entities such as HIV-associated arthritis and the painful articular syndrome have also been reported. Although initial reports described patients with mainly asymmetric oligoarthritis, a polyarticular presentation is now seen frequently. In Caucasians, HIV-associated reactive arthritis resembles reactive arthritis in non-HIV-infected persons. Reactive arthritis, psoriatic arthritis and undifferentiated spondyloarthropathy were uncommon in Africa and are now detected more often with the HIV epidemic. Although early reports in Western communities reported asymmetrical oligoarthritis as the usual pattern, polyarticular involvement is now seen frequently. Intravenous drug abuse is the most likely risk factor for septic arthritis, even in HIV-infected persons in Western communities, while HIV infection itself may be more important in developing countries where most patients do not receive highly active antiretroviral therapy (HAART). Recent reports have drawn attention to the development of avascular necrosis of the bone in HIV-positive patients and the risk factors include HAART itself, complications of HAART, HIV infection per se or concomitant conventional risk factors. Many patients respond to conventional symptomatic therapy, and disease-modifying drug therapy is necessary for patients who have persistent and progressive arthritis. The use of HAART can modify the prevalence or expression of the articular syndromes.
