title: Rheumatoid arthritis: an immune disease in search of an etiology.
abstract: The current knowledge of the immunologic and etiologic factors which play a role in rheumatoid arthritis is reviewed and extrapolated to the systemic effects of rheumatoid disease. The disease process is viewed as the incidental result of an atypical immuno-inflammatory mechanism initiated by an unidentified antigenic stimulus.
