title: Uveitis and arthritis induced by adjuvant: clinical, immunologic and histologic characteristics.
abstract: The intradermal administration of complete Freund's adjuvant (CFA) containing Mycobacterium butyricum to Sprague-Dawley (SD) and Lewis strain rats results in polyarthritis and uveitis. Over 90% of the eyes examined from the SD rats given CFA had histologic evidence of anterior uveitis, clinically evident in only 20 to 28%. Many rats developed arthritis without clinical uveitis, but uveitis was rare in the absence of arthritis. Histologically, the ocular inflammation was characterized by a polymorphonuclear, and later, a lymphocytic infiltration of the iris and ciliary body with cells and fibrinous exudate in the anterior chamber and cells in the vitreous. Antibodies and cellular immunity to ocular (S antigen, alpha crystallin), articular (type II collagen, proteoglycan) and bacterial components (MDP), were demonstrated in some rats, but positive tests did not correlate with either articular or ocular disease. Ten percent of rats given type II collagen in incomplete Freund's adjuvant developed uveitis. Thus, the pathogenesis of the arthritis and uveitis in the adjuvant model may be mediated by lymphocytes which exhibit crossreactivity with antigens in these structures, although the specificity of such antigens has not been identified in our studies.
