[Autoimmune rheumatic diseases associated with HIV infection and its pathogenesis].

In autoimmune rheumatic diseases, retroviruses have been repeatedly discussed as important etiologic factors. However, despite a considerable amount of indirect evidence that retroviruses might indeed be involved in triggering or initiating autoimmune rheumatic diseases, clear cut direct evidence is still missing. Studies on autoimmune or rheumatic disorders associated with HTLV-I or HIV-I infection as well as new data from the autoimmune rheumatic mouse (MLR/1pr mouse) model might help to answer the questions how and what mechanisms retroviral infection may lead to autoimmune rheumatic diseases. From data obtained in patients with HIV-I infection, apoptosis and molecular mimicry to autoantigens opens new approaches to the study of rheumatic disease pathogenesis.
