Abstract
Radiographs of symptomatic joints were retrospectively evaluated in 24 patients with inflammatory arthritis and human immunodeficiency virus (HIV) infection. Clinically, 20 patients had a seronegative arthritis including Reiter syndrome (54%), psoriatic arthritis (17%), and undifferentiated forms of spondyloarthropathy (13%). These patients were indistinguishable radiographically from patients with typical seronegative disorders except for the predominance of lower-extremity abnormalities. Four patients (17%) had a rheumatoidlike arthritis defined as acute symmetric polyarthritis (ASP). With the exception of extensive proliferative periostitis, ASP simulated classic rheumatoid arthritis. HIV-associated arthritis was manifest during various stages of HIV infection. It preceded acquired immunodeficiency syndrome in 64% of patients with stage IV HIV infection. Awareness of the coexistence of HIV infection in patients with the above-mentioned arthritides is important, since immunosuppressive therapy, commonly used in the treatment of arthritis, can have detrimental effects in patients with HIV infection.
